摘　　要：为了满足EPS系统的性能和功能安全集成开发要求,建立EPS机电耦合HIL测试系统尤为重要。泛亚汽车整合MTS转向性能试验台和dSPACE实时仿真器,集成整车Carsim动力学模型,搭建了全新的EPS机电耦合HIL测试台架。基于该台架,对某项目EPS系统进行转向中心区(OC)操稳性能和轮速有效位故障模拟双移线(DLC)工况进行联合仿真HIL测试,获得了EPS系统OC工况性能客观试验数据和DLC轮速故障工况驾驶员避障峰值扭矩值,在没有物理样车的情况下对EPS系统性能集成和功能安全策略进行了提前测试验证。To meet the performance development and function safety requirement of EPS system,it is important to build up the effective EPS electronic testing system.PATAC integrate MTS steering performance bench with dSPACE HIL simulator,embed Carsim model to build new EPS HIL test system.Based on this bench,do On Center(OC)handling stability test and Double Lane Change(DLC)test with simulating wheel speed fault for a project.Get the objective test data of OC and the peak torque value of driver obstacle avoidance of DLC,which effectively supports the performance integrated development and functional safety verification of EPS before the real vehicle is available.
