Abstract:
A wheel stability control system for an electric vehicle including an electric motor, a drive inverter, and an electronic control unit (ECU) including a computer readable, non-transitory memory (memory) and an electronic processing unit (EPU). The memory stores information including an optimal acceleration and deceleration curve and the electrical characteristics of the electric motor. The EPU calculates the electrical moment of the electric motor from inputs from the drive inverter and the electrical characteristics of the electric motor. The ECU compares the electrical moment and the angular speed of the motor with the optimal acceleration and deceleration curve, and if the acceleration or deceleration of the electric motor is out of a predetermined range when compared to the optimal acceleration and the optimal deceleration, it reduces the electrical moment applied by the electric motor.
