摘　　要：为解决道路模拟试验中无法验证转向电控系统的问题,基于汽车道路模拟耐久性试验技术和汽车总线通信原理,提出了一种转向系统道路模拟台架试验方案进行转向系统的精确验证。首先在道路模拟试验台架中搭建转向系统的控制电路,然后使用总线工具软件按照时间顺序输出转向系统控制器控制信号至转向系统,最后,通过转向系统应变和转向盘力矩信号进行试验方案有效性验证。结果表明,该方法可在传统台架有效启动电动助力转向(EPS)系统的转向助力功能。In order to solve the problem that steering electric control system cannot be validated in road simulation test,this paper proposed a road simulation test bench test scheme of the steering system to verify the accuracy of the steering system based on the automobile road simulation durability test technology and the principle of automobile bus communication.Firstly,the control circuit of the steering system was built in the road simulation test bench;Then,the bus tool software was used to output the control signal of the steering system controller into the steering system according to time sequence;Finally,the effectiveness of the test scheme was verified by the strain of the steering system and the torque signal of the steering wheel.The result shows that the method enables to activate the EPS function in the traditional test rig.
