Predictive torque split for engine torque determination in multi-motor electrically all-wheel drive vehicles

A torque control method for a multi-motor range-extended electrified vehicle (REEV) having an electric all-wheel drive (eAWD) system, the torque control method comprising:

• obtaining, by a control system and from an input device, an unfiltered driver demand indicative of a torque request to be satisfied by an electrified powertrain of the REEV, wherein the electrified powertrain includes at least one electric motor associated with each of front and rear axles of the REEV and an engine and a generator configured to provide electrical energy to a battery system that powers the electric motors;
• utilizing, by the control system, the unfiltered driver demand for engine torque determination and for predicting a front and rear axle torque split;
• obtaining, by the control system, a filtered driver demand that is damped or delayed compared to the unfiltered driver demand;
• and
• utilizing, by the control system, the filtered driver demand for controlling the front and rear axle torque split by actuating the electric motors,
• wherein an engine torque delay is mitigated or eliminated thereby increasing the electrical energy to the battery system for increased availability in actuating the electric motors to control the front and rear axle torque split.
