For fully taking the advantage of independently controllable of torque of Four-wheel Independent Drive Electric Vehicle to enhance its stability,a 2-DOF vehicle reference model is set up based on Vehicle Dynamics foundation.On this basis,a variable universe fuzzy control strategy witch chose yaw rate as the control variable is designed.thus,For four-wheel motor torque adjustments are applied to adjust the yaw moment of the vehicle and achieved its stability control target.The variable universe fuzzy control method is verified by using Matlab/Simulink and CARSIM co-simulation environment.The results show that the variable universe fuzzy control strategy can makes the yaw rate and sideslip angle in the range of stable and enhances the handling stability of vehicle.
