基于Cruise的电动车整车性能参数匹配及仿真分析

Electric Vehicle Parameters Matching of Vehicle Performance and Simulation Analysis Based on Cruise

根据整车参数和整车性能指标对电动车的电机、电池以及传动比进行动力匹配设计,利用Cruise仿真软件建立整车模型、电机以及电池模型,对其动力性和经济性进行仿真分析。由仿真结果可知,最高车速、0~75 m加速时间、0~80 km/h加速时间以及续驶里程均符合初步设计要求。对电动车的动力性及经济性进行道路试验,对比道路试验与仿真分析的结果,发现道路试验所测数据与仿真结果基本符合,验证了基于Cruise的整车性能参数匹配的合理性和所建模型的准确性。

The power matching of the electric motor, battery and transmission ratio is designed according to the vehicle parameters and the vehicle performance indicators. The vehicle simulation model, the electric motor and the battery model were built for analyzing the power performance and the economy performance based on the Cruise simulation software. Results show that the maximum velocity, the acceleration time of the 0 -75 m and the 0 -80km/h, and the driving range act well with the design specification. Lastly, real ve-hicle test about the power performance and the economy performance were carried out on the car and the results were basically consist-ent with the simulation results. This further demonstrated the validity of the power system design based on Cruise simulation software.
