Abstract: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 components, 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.
