1. A device comprising:
a brake position sensor operationally coupled to a brake and providing a brake position signal, and
a controller including
a communication module structured to interpret the brake position signal,
a collection module structured to collect vehicle dynamics information,
a vehicle dynamics module structured to interpret the vehicle dynamics information, and
a sensor diagnostics module structured to determine a failure of the brake position sensor in response to the vehicle dynamics information and the brake signal,
wherein the vehicle dynamics module is further structured to determine the presence of at least one of a vehicle acceleration event and a vehicle deceleration event, and
wherein the sensor diagnostics module is further structured to determine the failure of the brake sensor in response to the at least one of the vehicle acceleration event and the vehicle deceleration event, and to determine a duration of the brake position signal indicating engagement of a service brake.
