Abstract:
A system includes a reference speed module and a motor control module. The reference speed module is configured to determine a reference speed range based on a speed of a left wheel of a pair of front or rear wheels of a vehicle and a speed of a right wheel of the pair of front or rear wheels. The right wheel is disconnected from the left wheel. The motor control module is configured to control at least one of a first electric motor and a second electric motor based on the reference speed range. The first electric motor is connected to the left wheel. The second electric motor is connected to the right wheel.
