Abstract
A method of reducing wheel slip and wheel locking in an electric traction vehicle includes receiving in a first controller a first signal value representative of a first amount of torque to be applied to at least one wheel of the electric traction vehicle by a motor coupled to the wheel and to the first controller, and a second signal value representative of a reference speed of the electric traction vehicle. The first and second signal values are generated by a second controller in communication with the first controller. The method also includes receiving in the first controller a third signal value representative of a speed of the at least one wheel, determining in the first controller a torque output signal using the first, second, and third signal values; and transmitting the torque output signal from the first controller to the motor.
