Funded by the project of National Nature Science Foundation "ISG speedMulti-coupling hybrid drivetrain Physics Simulation and Integrated Control ShiftStrategy study (project number:51075411)", a human-computer interacted driver-vehicle-road closed-loop simulation system is constructed in this article. Then weconducte a research on the HIL(hardware in loop) system together with its applicationtechnology. Besides, a test and simulation platform is built for the design of planetarygear coupling hybrid system with single motor as well as the validation andimprovement of the energy management strategy. The main works of this article arelisted as follows:①We first make an introduction of the research significance and importance of HILsimulation test method, based on which, we analyze the development process of vehiclecontrol system and the basic structure of HIL simulation system. Then according to thedevelopment history and research situation of HIL simulation system home and abroad,the main contents and the key technologies of human and hardware in the loop (H2IL)system is studied. At last, we confirmed the main works of this article.②The relationship of driver-vehicle-road system, especially the effect of driver’scontrolling-intent on the controlling-system is researched. Based on the system designmethod and the long-term development goal, we analyze the existing real-time-systemwhich is the key link of H2IL simulation system, and make a selection of the systemtype.③The structure of planetary gear coupling hybrid system with ISG single motor isanalyzed. Then we make a parts selection based on the vehicle performance afterstudying the drive mode of system. Finally the real-time simulation model of thecomplete vehicles and system unit is built based on control design and simulationtoolkit of LabVIEW.④The requirement of H2IL simulation system is analyzed, also the systemimplementation scheme is designed under realistic condition. A thorough research ofPXI real-time system is conducted, including the characters, applied occasion, as well asthe selection and hardware configuration of data acquisition card. Then aiming at thehardware constructure of real-time system, the development process and applicationmethod of FPGA and RT module is detailedly studied based on the LabVIEW development procedures. Besides, we build a operating environment of the driver anda virtual driving sence, to achieve the integration of driver-vehicle-road closed-loopsystem. At last, an initial structure of the H2IL simulation system is proposed.⑤B ased on the built H2IL system, the driver-vehicle-road closed-loop simulationof the vehicle energy management strategy is completed. the real driver involvedNEDC driving cycle follow speed test results show that the H2IL simulation systemdesigned in this article is effective，and the real time simulation model of the vehiclegoes well. The Driver-vehicle-road closed-loop simulation can be done in the H2ILsystem.
