opendbc
A Python API and CAN database for controlling and reading data from modern cars with ADAS interfaces.
What is opendbc?
opendbc is a Python API and database for interacting with a car's internal network (CAN bus). It allows developers to read vehicle data like speed and steering angle, and send commands to control steering, acceleration, and braking. The project serves as the foundational layer for the openpilot ADAS system, enabling aftermarket advanced driver-assistance features on supported vehicles.
Automotive engineers, researchers, and hobbyists interested in vehicle reverse engineering, developing ADAS features, or integrating custom software with modern car electronics. It's particularly relevant for those contributing to or building upon the openpilot ecosystem.
Developers choose opendbc because it provides a well-documented, safety-focused, and community-vetted open-source interface to vehicle CAN buses. Its extensive library of DBC files and structured porting framework significantly lowers the barrier to adding support for new car models compared to starting from scratch.
