Abstract
A vehicle speed module includes a speed arbitration module that receives at least two of a wheel speed, a transmission output speed (TOS), and an electric motor speed (EMS), and that determines a vehicle speed based on a comparison of the at least two of the wheel speed, the TOS, and the EMS. A speed diagnostic module selectively diagnoses a fault in one of a wheel speed sensor, a TOS sensor, and an EMS sensor based on the comparison.
