SYSTEM AND METHOD FOR REDUCING WHEEL SLIP AND WHEEL LOCKING IN AN ELECTRIC VEHICLE

摘要

A method of reducing wheel slip and wheel locking in an electric tractionvehicle includes receiving in a first controller a first signal valuerepresentative of a first amount of torque to be applied to at least one wheelof the electric traction vehicle by a motor coupled to the wheel and to thefirst controller, and a second signal value representative of a referencespeed of the electric traction vehicle. The first and second signal values aregenerated by a second controller in communication with the first controller.The method also includes receiving in the first controller a third signalvalue representative of a speed of the at least one wheel, determining in thefirst controller a torque output signal using the first, second, and thirdsignal values; and transmitting the torque output signal from the firstcontroller to the motor.
