Research on Joint Control of Four-Wheel Steering and Electronic Differential on Account of Pavement Parameter Identification

The joint control strategy of four-wheel steering and electronic differential on account of pavement parameter identification is proposed in the manuscript. On account of fuzzy control theory, the four-wheel steering and the electronic differential controllers are designed. By controlling the rear wheel rotation angle and reasonable distributing the driving torque, makes the vehicle actual values of parameters follow the ideal values. This strategy is verified by the joint simulation experiment of Carsim and Matlab/Simulink. The results show that the joint control strategy can ensure the stability of the vehicle.
