Abstract: This paper is concerned with the design of traction force control of an electric vehicle in 2WS-4WD mode using fuzzy reasoning. The electric vehicle is in a motor-in-wheel system, and the traction force in each wheel can be determined independently. The yaw moment is regulated by the motor torque to improve the handling and stability of the vehicle as well as the skidding of lyres. The input variables in the fuzzy control rules are treated as the error of yaw ratio and its time difference, and the slip ratio. The simulation results show that the proposed traction force control improves the performance more than the traction force without control.

Keywords: electric vehicles; fuzzy reasoning; vehicle handling; slip ratio; traction force control; yaw moment; fuzzy logic; fuzzy control; simulation; vehicle design.
