Abstract
Powertrain propulsive torque monitoring and remedial action techniques for a cruise control mode of an electrified vehicle comprise obtaining a set of inputs indicative of a driver torque request and a state/grade of a road along which the vehicle is traveling, operating in a cruise control mode including determining a total torque request for an electrified powertrain, determining and commanding a distribution of the total torque request to the electrified powertrain, and determining the road state/grade based on at least some of the set of inputs, and monitoring the operating in the cruise control mode including determining an actual torque being generated by the electrified powertrain, determining upper and lower acceptable torque limits for the cruise control mode based on the road state/grade, and taking remedial action regarding the cruise control mode when the actual torque is outside of the upper and lower acceptable torque limits.
