摘要:
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.

摘要:
A control system comprising a powertrain relay diagnostic module that determines a single continuous period that a powertrain relay voltage is less than an ignition relay voltage, that compares the single continuous period to a single predetermined period, and that diagnoses a powertrain relay out of correlation (OOC) error when the single continuous period is greater than or equal to the single predetermined period, and an ignition relay diagnostic module that diagnoses an ignition relay OOC error when the ignition relay voltage is less than the powertrain relay voltage for a first predetermined cumulative period within a first predetermined total period.
