The adhesion control is the basic technology of active safety for the four-wheel driven EV. In this paper, a novel adhesion control method based on fuzzy logic control is proposed. The control system can maximize the adhesion force without road condition information and vehicle speed signal. Also, the regulation torque to prevent wheel slip is smooth and the vehicle driving comfort is greatly improved. For implementation, only the rotating speed of the driving wheel and the motor driving torque signals are needed, while the derived information of the wheel acceleration and the skid status are used. The simulation and road test results have shown that the adhesion control method is effective for preventing slip and lock on the slippery road condition.

An anti-slip control strategy based on fuzzy logic is proposed in this paper for electric vehicle individually driven by in-wheel-motor. In the control system, according to the angular speed of in-wheel-motor and the motor output torque, the motor torque can be regulated to prevent wheel slip, while the road maximum adhesion force can be fully utilized without road condition information and vehicle speed signal. The simulation and road test results have shown that the fuzzy control algorithm is effective for anti-slip on the slippery road condition.

A new adhesion control method based on fuzzy control is proposed in this paper for in-wheel-motor-driven electric vehicle without using road condition information. In the control system, the input signals are angular speed and motor output torque of the wheel, and the output signal is the torque regulation command of the in-wheel-motor. The offline simulation and hardware-in-loop experiment results showed that the new control method is effective for wheel skid on the slippery road condition and the road maximum adhesion force can be fully utilized without road condition information.
