| 摘 要： | 建立了线控转向系统的数学模型,对前轮转角采用基于理想变传动比的前馈控制和期望横摆角速度反馈控制的动态校正控制算法,从而确定合适的前轮转角,实现前轮主动转向,在一定程度上减轻驾驶员负担。通过对两种附着系数路面进行仿真研究,可以得出采用该控制策略可以缩短车辆的反应时间,减小质心侧偏角稳态值及超调量,使线控转向车辆转向更加平稳,提高抗干扰性,改善车辆的操纵稳定性。

| Abstract: | A mathematical model of the steer-by-wire system was established,in which dynamic correction control algorithm based on feedforward control of the ideal variable ratio and the feedback control of yaw rate was adopted to determine the front wheel angle so that active steering of the front wheels was realized and the burden of the driver was reduced to some extent.A simulation study on two kinds of road with different friction coefficient shows that the control strategy can decrease the response time of vehic... |
