Abstract
Systems and methods for monitoring electrified vehicle powertrain propulsive torque and taking remedial action when needed involve continuously monitoring an error between the actual and requested propulsive torques and comparing the error to various threshold values. Error exceeding a particular threshold could be indicative of a malfunction, and the vehicle could be afforded an opportunity to regain equilibrium by temporarily decreasing torque output. When the error continues to exceed the threshold or another threshold, however, further remedial action could be required, such as shutting down the vehicle.
