摘要
描述了电动助力转向器的构造及其工作原理,对EPAS系统模型进行了简化,建立了EPAS机械动力学方程,推导出了电流比例控制策略下汽车转向灵敏度的传递函数方程,并在Matlab中进行了仿真计算,定性地阐述了电动机转动惯量等参数在汽车转向盘角阶跃输入下对系统响应特性的影响。
The main structure and operating principle of EPAS were described,the ERAS model was simplified, EPAS mechanism dynamics equation was established,the transfer function equation of steering sensitivity under the current proportion control strategy was deduced,and the simulation computation in the Matlab were carried out,and qualitative elaborated the influence of systematic response characteristics when the same structural parameters was applied to EPAS under the condition of steering wheel angle step input.
