Project Description

CO2MPAS is backward-looking longitudinal-dynamics CO2 and fuel-consumption simulator for light-duty M1 & N1 vehicles (cars and vans), specially crafted to calculate CO2 emissions of a vehicle subject to a NEDC test using the results of a WLTP test, according to the EU legislation (see History section, below).

It is an open-source project developed with Python-3.5+, using WinPython & Anaconda under Windows 7, Anaconda under MacOS, and standard python environment under Linux. It runs either as a console command or as a desktop GUI application, and it uses Excel-files for its input & output data.

Quick Start

You may find usage Guidelines in the wiki: https://github.com/JRCSTU/CO2MPAS-TA/wiki/CO2MPAS-user-guidelines

IF you are familiar with Python, AND IF you already have a full-blown python-3 environment (i.e. Linux or the all-in-one archive), AND IF you have familiarity with previous releases, THEN you can immediately start working with the following bash commands; otherwise follow the detailed instructions under sections ref: install and ref: usage.

## Install co2mpas:
$ pip uninstall co2mpas
$ pip install co2mpas

## Create a template excel-file for inputs:
$ co2mpas template vehicle_1.xlsx

###################################################
## Edit generated `./input/vehicle_1.xlsx` file. ##
###################################################

## Launch GUI, select the edited template as Input, and click `Run`:
$ co2gui

And the GUI pops up:

Further command-line alternatives:

## To synchronize the Dyno and OBD data with the theoretical:
$ datasync template --cycle wltp.class3b template.xlsx
$ datasync -O ./output times velocities template.xlsx#ref! dyno obd -i alternator_currents=integral -i battery_currents=integral

## Run batch simulator.
$ co2mpas batch vehicle_1.xlsx -O output -f

###################################################
## Inspect generated results inside `./output/`. ##
###################################################

## Run type approval command.
$ co2mpas ta vehicle_1.xlsx -O output -f

## Start using the DICE command-line tool:
$ co2dice --help

History

The European Commission has introduced the WLTP as test procedure for the type I test of the European type-approval of Light-duty vehicles as of September 2017. Its introduction has required the adaptation of CO2 certification and monitoring procedures set by European regulations (443/2009 and 510/2011). European Commission’s Joint Research Centre (JRC) has been assigned the development of this vehicle simulator to facilitate this adaptation.

The European Regulation setting the conditions for using CO2MPAS can be found in the Comitology Register after its adoption by the Climate Change Committee which took place on June 23, 2016.

For recent activity, check the changes.

Licensing

The CO2MPAS application, both executable and its sources, is distributed under the EUPL license. EUPL is “eventually” compatible with all major open-source licenses, whether copy-lefted or not, but in reality CO2MPAS does not contain any prior code to derive from - all the code is a property of JRC’s and covered by the said license.

The ALLINONE archive contains many python libraries installed in its standard python -folder, (co2mpas_ALLINONE-XXX\Apps\WinPython\python-YYY.amd64\Lib\) so CO2MPAS only “links dynamically” to them. A non-exhaustive list of python-libraries contained is listed in WinPython site plus those manually installed by JRC when installing CO2MPAS in ALLINONE. We are certain that all of them are open-source and can be freely re-distributed.

The ALLINONE contains also “external programs”, all of them open-source, except from the MS redistributable (Apps/vc_redist.x64.exe file) which is explicitly exempted from the usual restrictive MS Licenses.

All the logo and graphic work is our own, but without having registered for trademark; we are discouraged by the EU guidelines on the subject; subsequently we discourage their use without our consent, beyond their intended usage, which is to run CO2MPAS.

Install

On Windows you may install the latest all-In-One archive and ensure it contains (or upgrade to) the latest CO2MPAS python package; alternatively, you may install the developer version.

Tip

Installing and using ALLINONE is the official procedure for running CO2MPAS for Type Approval (TA).

All-In-One Installation under Windows

  • Download all-in-one archive from https://github.com/JRCSTU/CO2MPAS-TA/releases/ (it only runs on 64bit PCs).

    Tip

    Search in older releases if the latest does not contain an ALLINONE archive, and remember to upgrade CO2MPAS afterwords.

  • Use the original “7z” extractor, since “plain-zip” application produces out-of-memory errors when expanding long directories.

    Note

    Prefer to extract it in a folder without any spaces in its path.

  • Run INSTALL.bat script contained in the root of the unzipped folder. It will install links for commons CO2MPAS tasks under your Windows Start-Menu.

  • You can start CO2MPAS from Windows start-menu by pressing the [WinKey] and start typing ‘co2mpas’, or by selecting the CO2MPAS menu item from All Programs.

    Alternatively, advanced users may continue to use the Console.

Note

If you have downloaded an all-in-one from previous version of CO2MPAS you may upgrade CO2MPAS contained within. Follow the instructions in the “Upgrade” section, below.

Upgrade CO2MPAS

Uninstall and re-install it from the CO2MPAS CONSOLE:

pip uninstall co2mpas
pip install co2mpas

Tip

Don’t forget verify that the installed version is the correct one by checking the output of this command:

co2mpas -vV

Upgrade CO2MPAS in a corporate environment

Note

This option has been retracted - please either download ALLINONE or just the wheel from https://pypi.org/project/co2mpas/ and install it, asuming that no other dependencies have changed.

Generic Tips

  • You may freely move & copy this folder around. But prefer NOT TO HAVE SPACES IN THE PATH LEADING TO IT.

  • To view & edit textual files, such as .txt, .bat or config-files starting with dot(.), you may use the “ancient” Window notepad editor, but it will save you from a lot of trouble if you download and install notepad++ from: http://portableapps.com/apps/development/notepadpp_portable (no admin-rights needed).

    Even better if you combine it with the “gem” file-manager of the ‘90s, TotalCommander, from http://www.ghisler.com/ (no admin-rights needed). From inside this file-manager, F3 key-shortcut views files.

  • The Cygwin POSIX-environment and its accompanying bash-shell are a much better choice to give console-commands compare to cmd.exe prompt, supporting auto-completion for various commands (with [TAB] key) and enhanced history search (with [UP]/[DOWN] cursor-keys).

    There are MANY tutorials and crash-courses for bash:

  • The console automatically copies into clipboard anything that is selected with the mouse. In case of errors, copy and paste the offending commands and their error-messages to emails sent to JRC.

  • When a new CO2MPAS version comes out it is not necessary to download the full ALLINONE archive, but you choose instead to just upgrade co2mpas.

    Please follow the upgrade procedure in the main documentation.

Usage

The sections below constitute a “reference” for CO2MPAS - a tutorial is maintained in the wiki for this project at: https://github.com/JRCSTU/CO2MPAS-TA/wiki/CO2MPAS-user-guidelines

CO2MPAS GUI

>From “Rally” release, CO2MPAS can be launched through a Graphical User Interface (GUI). Its core functionality is provided from within the GUI. Just ensure that the latest version of CO2MPAS is properly installed, and that its version is the latest released, by checking the “About” menu, as shown in the animation, below:

Alternatively, open the CONSOLE and type the following command:

## Check co2mpas version.
$ co2mpas -V
co2mpas-1.5.5.post0

CO2MPAS command syntax

To get the syntax of the CO2MPAS console-command, open a console where you have installed CO2MPAS (see ref: install above) and type:

    # Run co2mpas with ta cmd:
    co2mpas  batch  input/co2mpas_demo-0.xlsx  -O output

    # or launch the co2mpas GUI:
    co2mpas  gui

    # View all model defaults in yaml format:
    co2maps modelconf -O output

Input template

The sub-commands batch (Run) and ta (Run TA) accept either a single input-excel-file or a folder with multiple input-files for each vehicle. You can download an empty input excel-file from the GUI:

Or you can create an empty vehicle template-file (e.g., vehicle_1.xlsx) inside the input-folder with the template sub-command:

$ co2mpas template input/vehicle_1.xlsx -f
Creating TEMPLATE INPUT file 'input/vehicle_1.xlsx'...

The generated file contains descriptions to help you populate it with vehicle data. For items where an array of values is required (e.g. gear-box ratios) you may reference different parts of the spreadsheet following the syntax of the “xlref” mini-language.

Tip

For an explanation of the naming of the fields, read the ref: excel-model section

Demo files

The simulator contains demo-files that are a nice starting point to try out. You can download the demo vehicles from the GUI:

Or you can create the demo files inside the input-folder with the demo sub-command:

Synchronizing time-series

The model might fail in case your time-series signals are time-shifted and/or with different sampling rates. Even if the run succeeds, the results will not be accurate enough, because the data are not synchronized with the theoretical cycle.

As an aid tool, you may use the datasync tool to “synchronize” and “resample” your data, which have been acquired from different sources.

To get the syntax of the datasync console-command, open a console where you have installed CO2MPAS and type:

## datasync help.
$ datasync --help

Shift and resample excel-tables; see http://co2mpas.io/usage.html#Synchronizing-time-series.

Usage:
  datasync template [-f] [--cycle <cycle>] <excel-file-path>...
  datasync          [-v | -q | --logconf=<conf-file>] [--force | -f]
                    [--interp <method>] [--no-clone] [--prefix-cols]
                    [-O <output>] <x-label> <y-label> <ref-table>
                    [<sync-table> ...] [-i=<label=interp> ...]
  datasync          [-v | -q | --logconf=<conf-file>] (--version | -V)
  datasync          (--interp-methods | -l)
  datasync          --help

Options:
  <x-label>              Column-name of the common x-axis (e.g. 'times') to be
                         re-sampled if needed.
  <y-label>              Column-name of y-axis cross-correlated between all
                         <sync-table> and <ref-table>.
  <ref-table>            The reference table, in *xl-ref* notation (usually
                         given as `file#sheet!`); synced columns will be
                         appended into this table.
                         The captured table must contain <x_label> & <y_label>
                         as column labels.
                         If hash(`#`) symbol missing, assumed as file-path and
                         the table is read from its 1st sheet .
  <sync-table>           Sheets to be synced in relation to <ref-table>, also in
                         *xl-ref* notation.
                         All tables must contain <x_label> & <y_label> as column
                         labels.
                         Each xlref may omit file or sheet-name parts; in that
                         case, those from the previous xlref(s) are reused.
                         If hash(`#`) symbol missing, assumed as sheet-name.
                         If none given, all non-empty sheets of <ref-table> are
                         synced against the 1st one.
  -O=<output>            Output folder or file path to write the results

SUB-COMMANDS:
    template             Generate "empty" input-file for the `datasync` cmd as
                         <excel-file-path>.


Examples::

    ## Read the full contents from all `wbook.xlsx` sheets as tables and
    ## sync their columns using the table from the 1st sheet as reference:
    datasync times velocities folder/Book.xlsx

    ## Sync `Sheet1` using `Sheet3` as reference:
    datasync times velocities wbook.xlsx#Sheet3!  Sheet1!

    ## The same as above but with integers used to index excel-sheets.
    ## NOTE that sheet-indices are zero based!
    datasync times velocities wbook.xlsx#2! 0

    ## Complex Xlr-ref example:
    ## Read the table in sheet2 of wbook-2 starting at D5 cell
    ## or more Down 'n Right if that was empty, till Down n Right,
    ## and sync this based on 1st sheet of wbook-1:
    datasync times velocities wbook-1.xlsx  wbook-2.xlsx#0!D5(DR):..(DR)

    ## Typical usage for CO2MPAS velocity time-series from Dyno and OBD
    ## (the ref sheet contains the theoretical velocity profile):
    datasync template --cycle wltp.class3b template.xlsx
    datasync -O ./output times velocities template.xlsx#ref! dyno obd -i alternator_currents=integral -i battery_currents=integral

Datasync input template

The sub-command datasync accepts a single input-excel-file. You can download an empty input excel-file from the GUI or you can use the template sub-command:

Or you can create an empty datasync template-file (e.g., datasync.xlsx) inside the sync-folder with the template sub-command:

$ datasync template sync/datasync.xlsx --cycle wltp.class3b -f
2016-11-14 17:14:00,919: INFO:__main__:Creating INPUT-TEMPLATE file 'sync/datasync.xlsx'...

All sheets must share 2 common columns times and velocities (for datasync cmd are <x-label> and <y-label>). These describe the reference signal that is used to synchronize the data.

The ref sheet (<ref-table>) is considered to contain the “theoretical” profile, while other sheets (dyno and obd, i.e. <sync-table> for datasync cmd) contains the data to synchronize and resample.

Run datasync

Fill the dyno and obd sheet with the raw data. Then, you can synchronize the data, using the GUI as follows:

Or you can synchronize the data with the datasync command:

datasync times velocities template.xlsx#ref! dyno obd -i alternator_currents=integral -i battery_currents=integral

Note

The synchronized signals are added to the reference sheet (e.g., ref).

  • synchronization is based on the fourier transform;
  • resampling is performed with a specific interpolation method.

All tables are read from excel-sheets using the xl-ref syntax.

Run batch

The default sub-command (batch) accepts either a single input-excel-file or a folder with multiple input-files for each vehicle, and generates a summary-excel-file aggregating the major result-values from these vehicles, and (optionally) multiple output-excel-files for each vehicle run.

To run all demo-files (note, it might take considerable time), you can use the GUI as follows:

Note

the file co2mpas_simplan.xlsx has the flag.engineering_mode set to True, because it contains a “simulation-plan” with non declaration data.

Or you can run CO2MPAS with the batch sub-command:

$ co2mpas batch input -O output
2016-11-15 17:00:31,286: INFO:co2mpas_main:Processing ['../input'] --> '../output'...
  0%|          | 0/11 [00:00<?, ?it/s]: Processing ../input\co2mpas_demo-0.xlsx
...
...
Done! [527.420557 sec]

Note

For demonstration purposes, some some of the actual models will fail; check the summary file.

Run Type-Approval (ta) command

The Type Approval command simulates the NEDC fuel consumption and CO2 emission of the given vehicle using just the required declaration inputs (marked as compulsory inputs in input file version >= 2.2.5) and produces an NEDC prediction. If CO2MPAS finds some extra input it will raise a warning and it will not produce any result. The type approval command is the CO2MPAS running mode that is fully aligned to the WLTP-NEDC correlation Regulation.

The sub-command ta accepts either a single input-excel-file or a folder with multiple input-files for each vehicle, and generates a summary-excel-file aggregating the major result-values from these vehicles, and multiple output-excel-files for each vehicle run.

Note

The user can insert just the input files and the output folder.

To run the type approval command you can use the GUI as follows:

Or you can run CO2MPAS with the ta sub-command:

$ co2mpas ta input -O output
2016-11-15 17:00:31,286: INFO:co2mpas_main:Processing ['../input'] --> '../output'...
  0%|          | 0/1 [00:00<?, ?it/s]: Processing ../input\co2mpas_demo-0.xlsx
...
...
Done! [51.6874 sec]

Output files

The output-files produced on each run are the following:

  • One file per vehicle, named as <timestamp>-<inp-fname>.xls: This file contains all inputs and calculation results for each vehicle contained in the batch-run: scalar-parameters and time series for target, calibration and prediction phases, for all cycles. In addition, the file contains all the specific submodel-functions that generated the results, a comparison summary, and information on the python libraries installed on the system (for investigating reproducibility issues).
  • A Summary-file named as <timestamp>-summary.xls: Major CO2 emissions values, optimized CO2 parameters values and success/fail flags of CO2MPAS submodels for all vehicles in the batch-run.

Custom output xl-files as templates

You may have defined customized xl-files for summarizing time-series and scalar parameters. To have CO2MPAS fill those “output-template” files with its results, execute it with the -D flag.output_template=file/path.xlsx option.

To create/modify one output-template yourself, do the following:

  1. Open a typical CO2MPAS output-file for some vehicle.

  2. Add one or more sheets and specify/referring CO2MPAS result-data using named-ranges.

    Warning

    Do not use simple/absolute excel references (e.g. =B2). Use excel functions (indirect, lookup, offset, etc.) and array-functions together with string references to the named ranges (e.g. =indirect("output.prediction.nedc_h.pa!_co2_emission_value")).

  3. (Optional) Delete the old sheets and save your file.

  4. Use that file together with the -D flag.output_template=file/path.xlsx argument.

Simulation plan

It is possible to launch CO2MPAS once, and have it run the model multiple times, with variations on the input-data, all contained in a single (or more) input file(s).

The data for base model are contained in the regular sheets, and any variations are provided in additional sheets which names starting with the plan. prefix. These sheets must contain a table where each row is a single simulation, while the columns names are the parameters that the user want to vary. The columns of these tables can contain the following special names:

  • id: Identifies the variation id.
  • base: this is a file path of a CO2MPAS excel input, this model will be used as new base vehicle.
  • run_base: this is a boolean. If true the base model results are computed and stored, otherwise the data are just loaded.

You can use the GUI as follows:

Note

the file co2mpas_simplan.xlsx has the flag.engineering_mode set to True, because it contains a “simulation-plan” with non declaration data.

Or you can run CO2MPAS with the batch sub-command:

$ co2mpas batch input/co2mpas_simplan.xlsx -O output
2016-11-15 17:00:31,286: INFO:co2mpas_main:Processing ['../input/co2mpas_simplan.xlsx'] --> '../output'...
  0%|          | 0/4 [00:00<?, ?it/s]: Processing ../input\co2mpas_simplan.xlsx
...
...
Done! [180.4692 sec]

Launch CO2MPAS from Jupyter(aka IPython)

You may enter the data for a single vehicle and run its simulation, plot its results and experiment in your browser using IPython.

The usage pattern is similar to “demos” but requires to have ipython installed:

  1. Ensure ipython with notebook “extra” is installed:

    Warning

    This step requires too many libraries to provide as standalone files, so unless you have it already installed, you will need a proper http-connectivity to the standard python-repo.

    $ pip install ipython[notebook]
    Installing collected packages: ipython[notebook]
    ...
    Successfully installed ipython-x.x.x notebook-x.x.x
    
  2. Then create the demo ipython-notebook(s) into some folder (i.e. assuming the same setup from above, tutorial/input):

    $ pwd                     ## Check our current folder (``cd`` alone for Windows).
    .../tutorial
    
    $ co2mpas ipynb ./input
    
  3. Start-up the server and open a browser page to run the vehicle-simulation:

    $ ipython notebook ./input
    
  4. A new window should open to your default browser (AVOID IEXPLORER) listing the simVehicle.ipynb notebook (and all the demo xls-files). Click on the *.ipynb file to “load” the notebook in a new tab.

    The results are of a simulation run already pre-generated for this notebook but you may run it yourself again, by clicking the menu:

    "menu" --> `Cell` --> `Run All`
    

    And watch it as it re-calculates cell by cell.

  5. You may edit the python code on the cells by selecting them and clicking Enter (the frame should become green), and then re-run them, with Ctrl + Enter.

    Navigate your self around by taking the tutorial at:

    "menu" --> `Help` --> `User Interface Tour`
    

    And study the example code and diagrams.

  6. When you have finished, return to the console and issue twice Ctrl + C to shutdown the ipython-server.

Debugging and investigating results

  • Make sure that you have installed graphviz, and when running the simulation, append also the -D flag.plot_workflow=True option.

    $ co2mpas batch bad-file.xlsx -D flag.plot_workflow=True
    

    A browser tab will open at the end with the nodes processed.

  • Use the modelgraph sub-command to plot the offending model (or just out of curiosity). For instance:

    $ co2mpas modelgraph co2mpas.model.physical.wheels.wheels
    

    code-block:: co2mpas

    code-block:: d
    alt:Flow-diagram Wheel-to-Engine speed ratio calculations.
    height:240
    width:320
    >>> import co2mpas
    >>> d = co2mpas.model.physical.wheels.wheels()
    
  • Inspect the functions mentioned in the workflow and models and search them in CO2MPAS documentation ensuring you are visiting the documents for the actual version you are using.

Model

Execution Model

The execution of CO2MPAS model for a single vehicle is a stepwise procedure of 3 stages: precondition, calibration, and prediction. These are invoked repeatedly, and subsequently combined, for the various cycles, as shown in the “active” flow-diagram of the execution, below:

code-block:: co2mpas

code-block:: dsp
opt:depth=-1
alt:Flow-diagram of the execution of various Stages and Cycles sub-models.
width:640
>>> import co2mpas
>>> dsp = co2mpas.model.model()

Tip

The models in the diagram are nested; explore by clicking on them.

  1. Precondition: identifies the initial state of the vehicle by running a preconditioning WLTP cycle, before running the WLTP-H and WLTP-L cycles. The inputs are defined by the input.precondition.wltp_p node, while the outputs are stored in output.precondition.wltp_p.
  2. Calibration: the scope of the stage is to identify, calibrate and select (see next sections) the best physical models from the WLTP-H and WLTP-L inputs (input.calibration.wltp_x). If some of the inputs needed to calibrate the physical models are not provided (e.g. initial_state_of_charge), the model will select the missing ones from precondition-stage’s outputs (output.precondition.wltp_p). Note that all data provided in input.calibration.wltp_x overwrite those in output.precondition.wltp_p.
  3. Prediction: executed for the NEDC and as well as for the WLTP-H and WLTP-L cycles. All predictions use the calibrated_models. The inputs to predict the cycles are defined by the user in input.prediction.xxx nodes. If some or all inputs for the prediction of WLTP-H and WLTP-L cycles are not provided, the model will select from `output.calibration.wltp_x nodes a minimum set required to predict CO2 emissions.

Excel input: data naming conventions

This section describes the data naming convention used in the CO2MPAS template (.xlsx file). In it, the names used as sheet-names, parameter-names and column-names are “sensitive”, in the sense that they construct a data-values tree which is then fed into into the simulation model as input. These names are split in “parts”, as explained below with examples:

  • sheet-names parts:

                base.input.precondition.WLTP-H.ts
                └┬─┘ └─┬─┘ └────┬─────┘ └─┬──┘ └┬┘
    scope────────┘     │        │         │     │
    usage──────────────┘        │         │     │
    stage───────────────────────┘         │     │
    cycle─────────────────────────────────┘     │
    sheet_type──────────────────────────────────┘
    

    First 4 parts above are optional, but at least one of them must be present on a sheet-name; those parts are then used as defaults for all parameter-names contained in that sheet. type is optional and specify the type of sheet.

  • parameter-names/columns-names parts:

                   plan.target.prediction.initial_state_of_charge.WLTP-H
                   └┬─┘ └─┬─┘ └────┬────┘ └──────────┬──────────┘ └──┬─┘
    scope(optional)─┘     │        │                 │               │
    usage(optional)───────┘        │                 │               │
    stage(optional)────────────────┘                 │               │
    parameter────────────────────────────────────────┘               │
    cycle(optional)──────────────────────────────────────────────────┘
    

    OR with the last 2 parts reversed:

                  plan.target.prediction.WLTP-H.initial_state_of_charge
                                         └──┬─┘ └──────────┬──────────┘
    cycle(optional)─────────────────────────┘              │
    parameter──────────────────────────────────────────────┘
    

Note

  • The dot(.) may be replaced by space.
  • The usage and stage parts may end with an s, denoting plural, and are not case-insensitive, e.g. Inputs.

Description of the name-parts

  1. scope:

    • base [default]: values provided by the user as input to CO2MPAS.
    • plan: values selected (see previous section) to calibrate the models and to predict the CO2 emission.
    • flag: values provided by the user as input to run_base and run_plan models.
  2. usage:

    • input [default]: values provided by the user as input to CO2MPAS.
    • data: values selected (see previous section) to calibrate the models and to predict the CO2 emission.
    • output: CO2MPAS precondition, calibration, and prediction results.
    • target: reference-values (NOT USED IN CALIBRATION OR PREDICTION) to be compared with the CO2MPAS results. This comparison is performed in the report sub-model by compare_outputs_vs_targets() function.
    • config: values provided by the user that modify the model_selector.
  3. stage:

    • precondition [imposed when: wltp-p is specified as cycle]: data related to the precondition stage.
    • calibration [default]: data related to the calibration stage.
    • prediction [imposed when: nedc is specified as cycle]: data related to the prediction stage.
    • selector: data related to the model selection stage.
  4. cycle:

    • nedc-h: data related to the NEDC High cycle.
    • nedc-l: data related to the NEDC Low cycle.
    • wltp-h: data related to the WLTP High cycle.
    • wltp-l: data related to the WLTP Low cycle.
    • wltp-precon: data related to the preconditioning WLTP cycle.
    • wltp-p: is a shortcut of wltp-precon.
    • nedc [default]: is a shortcut to set values for both nedc-h and nedc-l cycles.
    • wltp [default]: is a shortcut to set values for both wltp-h and wltp-l cycles.
    • all: is a shortcut to set values for nedc, wltp, and wltp-p cycles.
  5. param: any data node name (e.g. vehicle_mass) used in the physical model.

  6. sheet_type: there are three sheet types, which are parsed according to their contained data:

    • pl [parsed range is #A1:__]: table of scalar and time-depended values used into the simulation plan as variation from the base model.
    • pa [parsed range is #B2:C_]: scalar or not time-depended values (e.g. r_dynamic, gear_box_ratios, full_load_speeds).
    • ts [parsed range is #A2:__]: time-depended values (e.g. times, velocities, gears). Columns without values are skipped. COLUMNS MUST HAVE THE SAME LENGTH!
    ..note:: If it is not defined, the default value follows these rules:

    When scope is plan, the sheet is parsed as pl. If scope is base and cycle is missing in the sheet-name, the sheet is parsed as pa, otherwise it is parsed as ts.

Calibrated Physical Models

There are potentially eight models calibrated from input scalar-values and time-series (see reference):

  1. AT_model,
  2. electric_model,
  3. clutch_torque_converter_model,
  4. co2_params,
  5. engine_cold_start_speed_model,
  6. engine_coolant_temperature_model,
  7. engine_speed_model, and
  8. start_stop_model.

Each model is calibrated separately over WLTP_H and WLTP_L. A model can contain one or several functions predicting different quantities. For example, the electric_model contains the following functions/data:

  • alternator_current_model,
  • alternator_status_model,
  • electric_load,
  • max_battery_charging_current,
  • start_demand.

These functions/data are calibrated/estimated based on the provided input (in the particular case: alternator current, battery current, and initial SOC) over both cycles, assuming that data for both WLTP_H and WLTP_L are provided.

Note

The co2_params model has a third possible calibration configuration (so called ALL) using data from both WLTP_H and WLTP_L combined (when both are present).

Model selection

Note

Since v1.4.1-Rally, this part of the model remains disabled, unless the flag.use_selector is true.

For the type approval mode the selection is fixed. The criteria is to select the models calibrated from WLTP_H to predict WLTP_H and NEDC_H; and from WLTP_L to predict WLTP_L and NEDC_L.

While for the engineering mode the automatic selection can be enabled adding -D flag.use_selector=True to the batch command. Then to select which is the best calibration (from WLTP_H or WLTP_L or ALL) to be used in the prediction phase, the results of each stage are compared against the provided input data (used in the calibration). The calibrated models are THEN used to recalculate (predict) the inputs of the WLTP_H and WLTP_L cycles. A score (weighted average of all computed metrics) is attributed to each calibration of each model as a result of this comparison.

Note

The overall score attributed to a specific calibration of a model is the average score achieved when compared against each one of the input cycles (WLTP_H and WLTP_L).

For example, the score of electric_model calibrated based on WLTP_H when predicting WLTP_H is 20, and when predicting WLTP_L is 14. In this case the overall score of the the electric_model calibrated based on WLTP_H is 17. Assuming that the calibration of the same model over WLTP_L was 18 and 12 respectively, this would give an overall score of 15.

In this case the second calibration (WLTP_L) would be chosen for predicting the NEDC.

In addition to the above, a success flag is defined according to upper or lower limits of scores which have been defined empirically by the JRC. If a model fails these limits, priority is then given to a model that succeeds, even if it has achieved a worse score.

The following table describes the scores, targets, and metrics for each model:

Developers Installation

Python Installation

If you already have a suitable python-3 installation with all scientific packages updated to their latest versions, you may skip this 1st stage.

Note

Installing Python under Windows:

The program requires CPython-3, and depends on numpy, scipy, pandas, sklearn and matplotlib packages, which depend on C-native backends and need a C-compiler to install from sources.

In Windows it is strongly suggested NOT to install the standard CPython distribution that comes up first(!) when you google for “python windows”, unless you are an experienced python-developer, and you know how to hunt down pre-compiled dependencies from the PyPi repository and/or from the Unofficial Windows Binaries for Python Extension Packages.

Therefore we suggest that you download one of the following two scientific-python distributions:

  1. WinPython python-3 (64 bit)
  2. Anaconda python-3 (64 bit)

Install WinPython

The WinPython distribution is just a collection of the standard pre-compiled binaries for Windows containing all the scientific packages, and much more. It is not update-able, and has a quasi-regular release-cycle of 3 months.

  1. Install the latest python-3.4+ 64 bit from https://winpython.github.io/. Prefer an installation-folder without any spaces leading to it.

  2. Open the WinPython’s command-prompt console, by locating the folder where you just installed it and run (double-click) the following file:

    <winpython-folder>\"WinPython Command Prompt.exe"
    
  3. In the console-window check that you have the correct version of WinPython installed, and expect a similar response:

    > python -V
    Python 3.4.3
    
    REM Check your python is indeed where you installed it.
    > where python
    ....
    
  4. Use this console and follow ref: install-co2mpas-package instructions, below.

Install Anaconda

The Anaconda distribution is a non-standard Python environment that for Windows containing all the scientific packages we need, and much more. It is not update-able, and has a semi-regular release-cycle of 3 months.

  1. Install Anaconda python-3.4+ 64 bit from http://continuum.io/downloads. Prefer an installation-folder without any spaces leading to it.

    Note

    When asked by the installation wizard, ensure that Anaconda gets to be registered as the default python-environment for the user’s account.

  2. Open a Windows command-prompt console:

    "windows start button" --> `cmd.exe`
    
  3. In the console-window check that you have the correct version of Anaconda-python installed, by typing:

    > python -V
    Python 3.4.3 :: Anaconda 2.3.0 (64-bit)
    
    REM Check your python is indeed where you installed it.
    > where python
    ....
    
  4. Use this console and follow ref: install-co2mpas-package instructions, below.

Install CO2MPAS package

  1. Install CO2MPAS executable internally into your python-environment with the following console-commands (there is no prob if the 1st uninstall command fails):

    > pip uninstall co2mpas
    > pip install co2mpas
    Collecting co2mpas
    Downloading http://pypi.co2mpas.io/packages/co2mpas-...
    ...
    Installing collected packages: co2mpas
    Successfully installed co2mpas-1.5.5.post0
    

    Warning

    Installation failures:

    The previous step require http-connectivity for pip command to Python’s “standard” repository (https://pypi.python.org/). In case you are behind a corporate proxy, you may try one of the methods described in section Alternative installation methods, below.

    If all methods to install CO2MPAS fail, re-run pip command adding extra verbose flags -vv, copy-paste the console-output, and report it to JRC.

  2. Check that when you run CO2MPAS, the version executed is indeed the one installed above (check both version-identifiers and paths):

    > co2mpas -vV
    co2mpas_version: 1.5.5.post0
    co2mpas_rel_date: 2017-02-10 19:31:55
    co2mpas_path: d:\co2mpas_ALLINONE-64bit-v1.4.1\Apps\WinPython\python-3.4.3\lib\site-packages\co2mpas
    python_path: D:\co2mpas_ALLINONE-64bit-v1.4.1\WinPython\python-3.4.3
    python_version: 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:44:40) [MSC v.1600 XXX]
    PATH: D:\co2mpas_ALLINONE-64bit-v1.4.1\WinPython...
    

    Note

    The above procedure installs the latest CO2MPAS, which might be more up-to-date than the version described here!

    In that case you can either:

    1. Visit the documents for the newer version actually installed.
    2. “Pin” the exact version you wish to install with a pip command (see section below).

Install extras

Internally CO2MPAS uses an algorithmic scheduler to execute model functions. In order to visualize the design-time models and run-time workflows you need to install the Graphviz visualization library from: http://www.graphviz.org/.

If you skip this step, the modelgraph sub-command and the --plot-workflow option would both fail to run (see ref: debug).

Upgrade CO2MPAS (with internet connectivity)

  1. Uninstall (see below) and re-install it.

Uninstall CO2MPAS

To uninstall CO2MPAS type the following command, and confirm it with y:

> pip uninstall co2mpas
Uninstalling co2mpas-<installed-version>
...
Proceed (y/n)?

Re-run the command again, to make sure that no dangling installations are left over; disregard any errors this time.

Alternative installation methods

You may get multiple versions of CO2MPAS, from various places, but all require the use of pip command from a console to install:

Tip

In all cases below, remember to uninstall CO2MPAS if it’s already installed.

Remember also to store the installation logs with the -v --log options, particularly if you install a specific version from GitHub

  • Latest STABLE: use the default pip described command above.

  • Latest PRE-RELEASE: append the --pre option in the pip command.

  • Specific version: modify the pip command like that, with optionally appending --pre:

    pip install co2mpas==1.0.1 --process-dependency-links ... # Other options, like above.
    
  • Specific branch from the GitHub-sources:

    pip install -v log pip.log git+https://github.com/JRCSTU/co2mpas.git@dev --process-dependency-links
    
  • Specific commit from the GitHub-sources:

    pip install -v log pip.log git+https://github.com/JRCSTU/co2mpas.git@2927346f4c513a --process-dependency-links
    
  • Speed-up download: append the --use-mirrors option in the pip command.

  • (for all of the above) When you are behind an http-proxy: append an appropriately adapted option --proxy http://user:password@yourProxyUrl:yourProxyPort.

    Important

    To avert any security deliberations for this http-proxy “tunnel”, JRC cryptographically signs all final releases with one of those keys: - GPG key ID: 9CF277C40A8A1B08 form @ankostis - GPG key ID: 1831F9C2294A33CC for @vinci1it2000

    Your IT staff may validate their authenticity and detect man-in-the-middle attacks, however impossible.

  • (for all of the above) Without internet connectivity or when the above proxy cmd fails:

    1. Use an existing Python-3.5 environment; that might be an older ALLINONE, WinPython, Anaconda or Linux’s standard python environment.

    2. With with a “regular” browser and when connected to the Internet, pre-download locally and unzip the respective co2mpas_DEPENDENCIES-vX.X.XXX.7z file from the latest ALLINONE release (e.g. http://github.com/JRCSTU/CO2MPAS-TA/releases/). This archive contains all the dependent packages of CO2MPAS.

    3. Install CO2MPAS, referencing the above folder. Assuming that you unzipped the packages in the folder path/to/co2mpas_packages, use a console-command like this:

      pip install co2mpas  --no-index  -f path/to/co2mpas_packages --process-dependency-links
      

Install Multiple versions in parallel

In order to run and compare results from different CO2MPAS versions, you may use virtualenv command.

The virtualenv command creates isolated python-environments (“children-venvs”) where in each one you can install a different versions of CO2MPAS.

Note

The virtualenv command does NOT run under the “conda” python-environment. Use the conda command in similar manner to create child conda-environments instead.

  1. Ensure virtualenv command installed in your “parent” python-environment, i.e the “WinPython” you use:

    > pip install virtualenv
    

    Note

    The pip command above has to run only once for each parent python-env. If virtualenv is already installed, pip will exit gracefully.

  2. Ensure CO2MPAS uninstalled in your parent-env:

    > pip uninstall co2mpas
    

    Warning

    It is important for the “parent” python-env NOT to have CO2MPAS installed! The reason is that you must set “children venvs” to inherit all packages installed on their “parent” (i.e. numpy and pandas), and you cannot update any inherited package from within a child-env.

  3. Move to the folder where you want your “venvs” to reside and create the “venv” with this command:

    > virtualenv --system-site-packages co2mpas_v1.0.1.venv
    

    The --system-site-packages option instructs the child-venv to inherit all “parent” packages (numpy, pandas).

    Select a venv’s name to signify the version it will contains, e.g. co2mpas_v1.0.1.venv. The .venv at the end is not required, it is just for tagging the venv folders.

  4. “Activate” the new “venv” by running the following command (notice the dot(.) at the begining of the command):

    > .\co2mpas_v1.0.1.venv\Scripts\activate.bat
    

    Or type this in bash:

    $ source co2mpas_v1.0.1.venv\Scripts\activate.bat
    

    You must now see that your prompt has been prefixed with the venv’s name.

  1. Install the CO2MPAS version you want inside the activated venv. See the ref: install-co2mpas-package section, above.

    Tip

    Always store the installation logs, particularly if you install a specific version from GitHub:

    pip install -v log pip.log ...  ## co2mpas specifiers follows here...
    

    Don’t forget afterwards to check that what you get when running CO2MPAS is what you installed.

  2. To “deactivate” the active venv, type:

    > deactivate
    

    The prompt-prefix with the venv-name should now dissappear. And if you try to invoke CO2MPAS, it should fail.

Tip

  • Repeat steps 2–>5 to create venvs for different versions of co2mpas.
  • Use steps (6: Activate) and (9: Deactivate) to switch between different venvs.

Autocompletion

In order to press [Tab] and get completions, do the following in your environment (ALLINONE is pre-configured with them):

  • For the Clink environment, on cmd.exe, add the following lua script inside clink’s profile folder: clink/profile/co2mpas_autocompletion.lua

    --[[ clink-autocompletion for CO2MPAS
    --]]
    local handle = io.popen('co2mpas-autocompletions')
    words_str = handle:read("*a")
    handle:close()
    
    function words_generator(prefix, first, last)
        local cmd = 'co2mpas'
        local prefix_len = #prefix
    
        --print('P:'..prefix..', F:'..first..', L:'..last..', l:'..rl_state.line_buffer)
        if prefix_len == 0 or rl_state.line_buffer:sub(1, cmd:len()) ~= cmd then
            return false
        end
    
        for w in string.gmatch(words_str, "%S+") do
            -- Add matching app-words.
            --
            if w:sub(1, prefix_len) == prefix then
                clink.add_match(w)
            end
    
            -- Add matching files & dirs.
            --
            full_path = true
            nf = clink.match_files(prefix..'*', full_path)
            if nf > 0 then
                clink.matches_are_files()
            end
        end
        return clink.match_count() > 0
    end
    
    sort_id = 100
    clink.register_match_generator(words_generator)
    
  • For the bash shell just add this command in your ~/.bashrc (or type it every time you open a new console):

    complete -fdev -W "`co2mpas-autocompletions`" co2mpas
