Abstract:
Methods and systems are provided for propelling a hybrid electric vehicle under circumstances where a torque degradation event associated with an electric machine that is used for propulsive effort is indicated. In one example, a method may include propelling the vehicle at least in part via a first electric machine that provides torque to front wheels and/or via a second electric machine that provides torque to rear wheels of the vehicle, and continuing to propel the vehicle via adjusting operation of both the first and the second electric machine in response to an indication of a torque degradation event associated with one of the electric machines. In this way, a vehicle shutdown event may be avoided.
