The pure electric vehicle model plays an important role in the HIL(Hardware-In-Loop)test of the control system.Based on the dSPACE real-time simulation platform,this paper establishes a vehicle model for HIL testing,and conducts closed-loop testing with a rapid prototype controller.Firstly,the vehicle subsystem model is established based on the researched vehicle structure and parameters.Then,in order to realize the closed-loop test with the vehicle control system,the interface between the model and the vehicle control system was configured.Finally,based on dSPACE&s SCALEXIO simulation simulator and MicroAutobox rapid prototyping controller,a hardware-in-the-loop test platform was established to conduct open-loop and closed-loop tests between the vehicle controlled object model and control strategy.The results show that the vehicle HIL model built in this paper can realize real-time simulation based on the dSPACE platform,which can reflect the performance of the vehicle,and can be applied to the HIL test of the vehicle control system.
