自动变速器换档规律研究

Shifting Rule of Automatic Transmission

对于特定的车辆参数,通过对自动变速器换档规律进行研究,从不同油门开度下的最大牵引力,得出整车最佳动力性换档规律;从不同油门开度下的最小牵引功率比油耗,得出最佳经济性换档规律,满足整车动力性和经济性的驾驶要求。

With regard to a specific vehicle parameter,through the study on shifting rule of automatic transmission,this paper obtains optimal power shifting rule of vehicle from the maximum traction force under different opening degree of throttle,and obtains best economical shifting rule from minimum traction power oil consumption under different opening degree of throttle,which meet power and economy performance requirements of vehicle driving.
