摘要
文章描述了一种纯电动汽车陡坡缓降控制系统的实现方法,为了分析该系统制动和能量回收功能的性能,建立了该系统的仿真模型并进行了仿真分析。结果表明,纯电动汽车在执行陡坡缓降控制功能的过程中,可以使得车速逐渐减小到目标值,实现陡坡缓降控制系统的制动功能。同时,在实现制动功能的过程中,能够进行能量回收。说明该系统在一定程度上提高了纯电动汽车的安全性、舒适性以及续航里程。
An implementation method of a hill descent control system for electric vehicles was described in this paper. In order to analyze the braking and energy recovery performance of the system, a simulation model of the system was established and the simulation analysis was carried out.The results show that when the electric vehicle implements hill descent control function, the vehicle speed can be gradually reduced to the target value and the braking function can be realized. At the same time, in the process of braking the vehicle, it can also realize the function of energy recovery. It shows that the system improves the safety, comfort and driving range of the electric vehicle.
