【Abstract】 Based on analysis of the pure electric vehicle electrical construction,this paper discusses one simulation architecture and realization which could meet the requirements of digital simulation and hardware in the loop simulation. This simulation system with higher simulation precision provides simulation environment for development and performance evaluation of drive strategy. This paper describes the compositions of simulation system. On this basis,the simulation system is established by application high precision vehicle dynamics model,battery experimental model,motor model,the actual sensors and actuators and real-time simulation system dSPACE. This realization could improve accuracy simulation of dynamic characteristics and make the simulation environment consistent with the actual vehicles. Then riding conditions of simulation system for vehicle control is simulated by starting,accelerating,and braking operations. By comparing the simulation data with the experiment data,the results show that the models built in this paper is validated.更多还原
