BELT LOSS CONSIDERATION FOR DETERMINATION OF ELECTRIC MOTOR TORQUE SPLIT

Torque control techniques for a multi-motor electrified powertrain of an electrified vehicle include determining a total torque request to be satisfied by the multi-motor electrified powertrain, wherein a first electric motor is connected to a crankshaft of an engine via a belt as part of a belt-driven starter-generator (BSG), estimating a torque loss associated with the belt based on stored data and an engine speed or a BSG speed, determining an optimized torque split of the total torque request between the first electric motor and a second electric motor based on the estimated belt torque loss and to minimize battery power, determining torque commands for the engine and the first and second electric motors based on the determined optimized torque split, and controlling the multi-motor electrified powertrain based on the determined torque commands for the engine and the first and second electric motors.
