opendbc

opendbc is a Python API for your car. Read the speed, steering angle, and more. Send gas, braking, and steering commands.

Structure

• opendbc/dbc/ is a repository of DBC files
• opendbc/can/ is a library for parsing and building CAN messages from DBC files
• opendbc/car/ is a high-level library for interfacing with cars using Python

Quick start

git clone https://github.com/commaai/opendbc.git cd opendbc # Install the dependencies pip3 install -e .[testing,docs] # Build scons -j8 # Run the tests pytest . # Run the linter pre-commit run --all-files

examples/ contains small example programs that can read state from the car and control the steering, gas, and brakes. examples/joystick.py allows you to control a car with a joystick.

Roadmap

This project was pulled out from openpilot. We're still figuring out the exact API between openpilot and opendbc, so some of these may end up going in openpilot.

• Extend support to every car with LKAS + ACC interfaces
• Automatic lateral and longitudinal control/tuning evaluation
• Auto-tuning for lateral and longitudinal control
• Automatic Emergency Braking
• pip install opendbc
• 100% type coverage
• 100% line coverage
• Make car ports easier: refactors, tools, tests, and docs
• Expose the state of all supported cars better: #1144
