摘要
换档规律是自动变速器控制系统的核心技术,其控制参数选择的合理性直接影响纯电动汽车的动力性、舒适性和续驶里程.用纯电动汽车行驶加速度和加速踏板位置作为换挡控制参数,分别设计出动力性和经济性两种换挡规律,并用CRUISE软件进行仿真和优化,得出适合某型电动汽车变速器的换挡规律,实现了节能与增加续驶里程的目的.
Shift schedule as the core technology of the automatic transmission control sys reasonable choice of its control parameters , will directly affect the dynamic performance, comfort and the driving range of the vehicle. By using the method of combing the theoretical and the trial, of vehicle acceleration and accelerator pedal position as shift control parameters, the reasonable shift schedules which are suitable for the certain type of transmission, so as to the purpose of saving energy and increasing the driving range of the electric vehicle. tem, the the ride research designs achieve
