Abstract: A control system for a vehicle includes wheel slip control loop including a wheel slip controller configured to control wheel slip based on wheel speed measured at one or more wheels of the vehicle. A wheel flare control loop includes a wheel flare controller configured to control wheel flare based on transmission output speed at an output of a transmission of the vehicle. A controller is configured to select one of the wheel slip controller to control the wheel slip and the wheel flare controller to control the wheel flare during operation of the vehicle.

Abstract: A wheel speed sensor is configured to generate pulses based on teeth that rotate with a wheel passing the wheel speed sensor. A wheel speed module is configured to receive first and second pulses, retrieve from memory a previous compensated wheel speed determined for the second time, determine a measured wheel speed at the first time and a previous measured wheel speed at the second time based on the first and second pulses, and determine a present compensated wheel speed for the first time based on (a) the measured wheel speed at the first time, (b) the previous compensated wheel speed for the second time and (c) a measurement latency of the wheel speed sensor. A control module is configured to actuate an actuator of the vehicle based on the present compensated wheel speed.

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.
