Abstract: Improvements to steering functionality and safety thereof for a vehicle are disclosed. In particular, disclosed embodiments monitor and diagnose steering commands received by an in-vehicle controller from a remote server. The steering commands may be evaluated with respect to rationality and context. For example, a steering angle indicated by the steering command is compared to a current vehicle steering angle and/or to other steering angles indicated by preceding and/or subsequent steering commands. Based on diagnosis of the steering commands, an in-vehicle controller can permit or prevent engagement of autonomous vehicle operation, which applies the steering commands. In an autonomous mode, invalid steering commands can trigger a minimal risk condition (MRC) maneuver for the vehicle.
