- johschmitz 9mo agoThe control messages are transmitted via CAN bus https://en.wikipedia.org/wiki/CAN_bus https://en.wikipedia.org/wiki/CAN_bus The exact message content and protocols are reverse engineered. Some cars use FlexRay instead of CAN bus but that has only experimental support.
- grepfru_it 9mo agoFlexray is supported only on Audi on a specific Flexray-canbus integration board that was just end of lifed and Comma has no desire to support other boards. It was a proof of concept for anyone wishing to implement the same
- ActorNightly 9mo agoIt requires a car with lane centering capabilities -i.e a module that commands the steering angle through canbus. Thats why not all cars are supported.
- georgehotz 9mo agoYea most modern cars have a Python API. https://github.com/commaai/opendbc https://github.com/commaai/opendbc
