Novel skid detection method without vehicle chassis speed for electric vehicle

Abstract A novel wheel skid detection method without chassis velocity for electric vehicle (EV) is proposed. The proposed method can sense the skid with only the values of current and rotating velocity of the motor. The output torque of the motor is easily comprehensible, and the proposed method utilizes this advantage of EV. Estimation of vehicle chassis velocity or wheel absolute velocity is not required. The experiments were carried out with laboratory-made electric vehicle “UOT Electric March I”, and the results show the effectiveness of this method. We also carried out some simulations to discuss how to prevent the wheel skid with this skid detector.
