摘要
系统地分析了二自由度四轮转向汽车模型的运动方程 ,得出了质心侧偏角、横摆角速度与前轮转角的传递函数。在此基础上 ,对四轮转向样车进行了前后轮转角成比例控制的四轮转向车辆 (4WS)的运动学仿真 ,并针对仿真结果进行了系统的分析。结果阐明了四轮转向车辆与前轮转向车辆 (2WS)相比的优势 ,并提出其发展方向。
The equations of 2DOF Four wheel steering vehicle model are systemically analyzed,and the transfer functions about sideslip angle of mass center and yaw velocity to front wheel steering angle are deduced.The locomotion simulations were processed according to the parameters of the four wheel steering model vehicle in my lab whose control strategy is proportional control.The systemic analysis was done on the base of the results of simulation.And the advantages of 4WS vs.2WS were showed evidently.Finally,the developing directions of 4WS are put forward.
