电动汽车动力参数匹配及性能仿真

Parameter Matching of Power Train and Simulation of Performance for Pure Electric Vehicle

以某轻型客车为研究对象,采用理论设计方法对其动力传动系参数进行合理选型设计,应用电动汽车仿真软件ADVISOR建立该电动汽车的整车模型并进行了动力性能仿真计算。通过将仿真结果与理论计算结果比较表明:电动汽车动力性能主要技术指标的仿真值与理论计算值相比,误差控制在5%以内,从而验证动力传动系参数设计的合理性和整车仿真模型的正确性。

Based on a light bus, the parameters of power train were selected and designed reasonably by the method of theoretical design. The dynamic performance of the vehicle was built and simulated by using the simula- tion software of ADVISOR, which was an advanced simulator for electric vehicle. The comparison of the simulation results with the theoretical design results showed that the error was less than 5%. So the rationality of the designed parameters of the power train and the correctness of the simulation model are demonstrated.
