Open Source Car Control (OSCC) provides developers with a collection of firmware and hardware designs for computer control of their autonomous development vehicles. It's a modular, stable way of using software to interface with a vehicle’s communications network and control systems.
OSCC allows developers to:
- Send control commands to the vehicle
- Read control messages from the vehicle’s OBD-II CAN network
- Forward reports for current vehicle control states (e.g. steering angle & wheel speeds)
Control commands are issued to the vehicle component ECUs via the steering wheel torque sensor, throttle position sensor, and brake position sensor. (Because the petrol Kia Soul isn’t brake by-wire capable, an auxiliary actuator is added to enable braking.) This low-level interface means that OSCC offers full-range control of the vehicle without altering the factory safety-case, spoofing CAN messages, or hacking ADAS features.
Although we currently support only the 2014+ Kia Soul (w/ Kia Soul EV coming soon), the API and firmware have been designed to make it relatively easy to add functionality to any by-wire, OBD-II capable vehicle. Additionally, the separation between API and firmware means it's easier to modify and test parts of your program without having to update the flashed OSCC modules.
