ECU_TEST 使用说明
1. 包简介
ECU_TEST 是一个基于 Python 的 ECU 测试辅助包
2. 环境要求
请先确认环境中已经安装:
- Python 3.10+
- 依赖的构建工具(如有需要)
- Vector 驱动 / Vector 硬件(如果要实际通过 Vector 设备通信)
如果没有安装 Vector 驱动,初始化时可能会出现连接失败或无法收发数据的问题。
3. 安装方式
在项目根目录执行:
pip install .
如果你希望在开发模式下使用:
pip install -e .
4. 导入方式
安装完成后,可以这样导入:
from ecu_test import UDS, CANape, CANoe
5. 基本使用示例
5.1 配置参数
config = {
"tr_id": "0x7E0",
"rx_id": "0x7E8",
"ch": 1,
"fd": False,
"app_name": "CANoe",
"bitrate": 500000,
"stmin": 20,
"mask": "0xFF",
"pad": "0x55",
}
5.2 初始化 UDS 对象
uds = UDS(config, log_path="uds.log")
5.3 发送 UDS 请求
resp = uds.send_req("10 01", dlc=8, t=30)
print(resp)
5.4 初始化 CANape / CANoe 对象
canape = CANape()
canoe = CANoe()
5.5 CANape 使用说明
from ecu_test import CANape
canape = CANape(
path=r"E:\CANape\",
cna=r"E:\CANape\config.cna",
)
canape.set_log(r"E:\CANape\logs\test.mf4")
canape.start_mse()
value = canape.get_sig("SignalName")
canape.set_sig("SignalName", 1.23)
canape.stop_mse()
canape.close()
常用方法:
CANape(path, cna)set_log(file)start_mse()stop_mse()get_sig(sig)set_sig(sig, val)close()
5.6 CANoe 使用说明
from ecu_test import CANoe
canoe = CANoe(
path=r"D:\CANoe\CANoe_Test\CANoe_Test.cfg",
log_path="canoe.log",
)
canoe.open()
canoe.start_mse()
value = canoe.get_sig("CAN", "MessageName", "SignalName")
canoe.set_sig("CAN", "MessageName", "SignalName", 1.23)
env_value = canoe.get_env("Namespace", "VariableName")
canoe.set_env("Namespace", "VariableName", 42)
canoe.set_log(r"D:\CANoe\logs\test.blf")
canoe.stop_mse()
canoe.close()
常用方法:
CANoe(path)open()start_mse()stop_mse()is_running()get_sig(ch, msg, sig)set_sig(ch, msg, sig, val)get_env(ns, var)set_env(ns, var, val)set_log(file)close()
