摘　　要：目前,电动汽车结构呈现多样化,且研发周期越来越短。传统的测试台架已无法满足其测试需求。结合电动汽车发展现状及实际测试需求,为了在实验室环境下对动力总成各部件性能进行整车级集成测试,提出了整车仿真测试与试验台架相结合的设计方法,将虚拟现实驾驶模拟系统和台架动态加载控制系统集成,最大限度地模拟实车运行状况,检验关键部件的协调工作,以提升台架测试效率和产品开发周期。最后,以EM-CVT台架测试为例,验证了该台架测控系统的可行性。At present,the structure of electric vehicles is diversified,and the research and development cycle is getting shorter and shorter.Traditional test benches will be unable to meet the testing needs.In combination with the development status of electric vehicles and actual test requirements,and in order to carry out vehicle-level integration testing of the performance of powertrain components in a laboratory environment,a design method combining vehicle simulation test and test bench is proposed to simulate drive virtual reality.The simulation system and the platform dynamic loading control system are integrated to maximize the simulation of the actual vehicle running condition,by which to check the coordination of key compon ents,thus improving the bench testing efficiency and product development cycle.Finally,the EM-CVT bench test is taken as an example to verify the feasibility of the bench measurement and control system.
