【Abstract】 A practical nonlinear model and its dynamic equations for 4WS vehicles are established. The model can reflects the effects of main factors in practical structures on the vehicle motion. The nonlinear model presented here is proved be a feasible 4WS vehicle model for emergency maneuvers (greater lateral accelerations,possibly combined with longitudinal acceleration or braking),and is of greater precision and can be instructive to engineering practice.更多还原
