Simulation technology plays an important role in research and development process of control strategy for Hybrid Electric Vehicles（ HEVs）. Compared with offline simulation,the driver-in-the-loop real-time simulation can verify the control strategy＇s correctness and real-time more effectively. A novel driver-in-the-loop real-time simulation platform for HEVs was built up based on the D2 P product-level controller and NI Lab VIEW system,which has the advantages of low cost and easy to implementation. Taking a series-parallel HEV for example,this paper described the building process of the simulation platform in detail,and analyzed the real-time simulation of the series-parallel HEV. By comparing the real-time simulation data with the offline simulation results,it is found that the proposed platform has a good simulation precision.
