| Abstract: | The sensitivities and perturbation amount of vehicle motion stability were analyzed when several parameters of the vehicle varied simultaneously. The analysis is based on the model of driver vehicle with 4WS closed loop system and the nonsymmetrical matrix perturbation method. Some inherent relations of motion stability were revealed quantitatively for vehicle with 4WS and vehicle with front wheel steering system by simulation examples. The results show that the present method can direct the selection of vehicle design parameters, thus the handling and stability of vehicle can be enhanced. |
