To improve the stability and maneuverability of the vehicle when steering, a joint deflection-slip control strategy is proposed for a 4WD electric wheel vehicle(EWV)model. A vehicle two-track 2-degree-of-freedom dynamics model is established, and a sliding-mode controller based on the isokinetic convergence law is designed with the vehicle's transverse moment as the control target, the transverse target moment is obtained by adjusting the left and right wheel hub motor drive and braking torque, and a combined Carsim/Simulink simulation model is built to complete the simulation verification. The results show that with the application of deflection slip steering, the vehicle steering radius and the mass lateral deflection angle and transverse sway angle generated during steering are reduced, which enhances the steering stability and maneuverability of the vehicle.
