TECHNIQUES FOR DYNAMIC WHEEL SLIP TARGET CONTROL IN MULTI-MOTOR ELECTRIFIED VEHICLES

Dynamic slip target control systems and method for a multi-motor electrified powertrain of an electrified vehicle including a driveline having four wheels involve determining (i) a steering angle of the driveline of the electrified vehicle, (ii) a vehicle speed of the electrified vehicle, and (iii) a wheel speed of each the four wheels of the driveline, dynamically determining a target wheel slip based on a wheel speed model with inputs including the steering angle and vehicle speed, determining an expected differential speed based on the dynamically determined target wheel slip, determining a torque bias adjustment based on a difference between wheel speed errors and the expected differential speed, and controlling two or more electric motors of the multi-motor electrified powertrain based on an estimated torque bias and the torque bias adjustment.
