Abstract: A powertrain system is configured to transfer propulsion torque to a driveline of a vehicle. A method for controlling the powertrain system includes determining a magnitude of unintended vehicle motion based upon a difference between a change in actual vehicle acceleration and a change in an operator-intended vehicle acceleration. Propulsion torque to the driveline is limited when a fault associated with unintended vehicle motion is detected and the magnitude of unintended vehicle motion is less than a predetermined first threshold.

Abstract: An electric machine electrically connects to an inverter via a multi-phase power circuit. A method for monitoring the multi-phase power circuit includes non-intrusively adjusting a commanded AC electric current from the inverter after a prescribed time period and comparing a measured magnitude of AC electric current in the multi-phase power circuit with a minimum threshold. Presence of an open circuit fault in the multi-phase power circuit can be detected based upon the comparison.

Abstract: A system according to the principles of the present disclosure includes an acceleration delta module and a remedial action module. The acceleration delta module determines an acceleration delta of a vehicle based on a difference between an actual acceleration of the vehicle and a desired acceleration of the vehicle. The acceleration delta module also determines an average value of the acceleration delta corresponding to at least one of a first predetermined period and a predetermined number of samples of the acceleration delta. The remedial action module, based on the average value of the acceleration delta and independent of a torque command generated to accelerate the vehicle, selectively takes a remedial action by adjusting operation of at least one of an engine and an electric motor.
