Lightweight Embedded Assisted Driving System

LEADS: Lightweight Embedded Assisted Driving System

LEADS is a system designed for VeC.

LEADS only supports two drive-wheel configurations: single rear wheel (SRW) mode and dual rear wheel (DRW) mode.

Python is generally not the best choice for writing embedded systems. We made this decision for the following reasons.

• Data analysis
• Short development cycle
• Official support for Raspberry Pi
• Low difficulty in getting started for team members

This project aims to implement the following functions:

• A basic instrumentation system
• A basic communication system
• A basic control system
• A data recording system with the following components
  • A speed recording system
  • A G force recording system
  • A GPS recording system
  • A battery voltage recording system
• A control system with the following components
  • DTCS (Dynamic Traction Control System)
  • ABS (Anti-lock Braking System)
  • EBI (Emergency Braking Intervention)
  • ATBS (Automatic Trail Braking System)

Installation

Note that LEADS requires Python >= 3.11.

pip install pysimplegui keyboard pyserial leads

numpy will be automatically installed with leads.

pysimplegui, keyboard, and pyserial are optional.

If you need only the skeleton, run the following.

pip install leads

Quickstart

Main

python -m leads_vec

Remote Server (Remote)

python -m leads_vec --remote

Optional Arguments

Configuration File

python -m leads_vec config=path/to/the/config/file

If not specified, all configurations will be default values.

To learn about the configuration file, read Configurations.

Issues

Our team management completely relies on GitHub. Tasks are published and assigned as issues. You will be notified if you are assigned to certain tasks. However, you may also choose to join other discussions for which you are not responsible.

There are a few labels that classify the issues.

• bug reports a bug
• code review discusses a code review or comment
• documentation suggests a documentation enhancement
• duplicate marks that a similar issue has been raised
• enhancement proposes a new feature or request
• help wanted means that extra attention is needed to this issue
• invalid marks that the issue is in valid format
• question requests further information
• report starts a periodic report discussion
• todo creates a new task
• wontfix marks that the issue is ignored

Label your issue with at least one of the labels above before you submit.
