| 摘 要： | 为改善车辆的转向特性,提出了线控转向理想转向传动比控制规律的3种方案:方案1为期望横摆角速度增益不变的变传动比控制规律,方案2为期望侧向加速度增益不变的变传动比控制规律,方案3是由方案1与方案2按照一定的比例综合得到的控制规律.将这3种传动比控制规律引入整车模型,在Matlab/Simulink中对整车模型进行仿真,分析了不同传动比控制对整车操纵稳定性的影响,得到了各种变传动比控制规律的优缺点.仿真结果表明方案3的整体性能最优.

| Abstract: | In order to improve the steering behavior of the vehicle,three control programs of ideal steering ratio of steer-by-wire system(SBW) are introduced: the first is deduced by yaw rate,the second deduced by lateral acceleration,and the third deduced by yaw rate and lateral acceleration.The three control programs are brought into vehicle model and Matlab/Simulink. Influence of variable steering ratio control on vehicle handling stability is then analyzed,and the merits and drawbacks of the three programs are compared.Simulation results showed that the third program synthesizes the former two programs,and has the best integral performance. |
