The invention discloses a pure electric vehicle AMT gear shifting process control method based on driving style recognition. The method comprises the following steps: 1, collecting the opening degreeof a vehicle accelerator pedal, the vehicle speed and the vehicle acceleration of a current driver in the time period of [0, T]; 2, obtaining the average value of the opening degree of the vehicle accelerator pedal, the maximum value of the opening degree of the vehicle accelerator pedal, the average value of the vehicle speed, the maximum value of the vehicle speed, the average value of the vehicle acceleration and the maximum value of the vehicle acceleration in the time period [0, T]; 3, if G is larger than or equal to 0 and smaller than or equal to beta, determining that the driving styleof the driver is comfortable; if beta < G < = 100%, determining that the driving style of the driver is a sports type, wherein beta is the critical value of driver driving style comfort and sports type recognition, and G is the driver driving style recognition degree; and 4, through the driving style of the driver, obtaining the torque reduction rate, the speed regulation rate and the torque recovery rate of the driving motor in the gear shifting process. The method has the characteristic of improving the intelligent level of gear shifting.

    本发明公开一种基于驾驶风格识别的纯电动汽车AMT换挡过程控制方法,包括如下步骤:步骤1、采集当前驾驶员在[0,T]时间段内汽车加速踏板开度、汽车车速和汽车加速度;步骤2、得到[0,T]时间段内汽车加速踏板开度的平均值、汽车加速踏板开度的最大值、汽车车速的平均值、汽车车速的最大值、汽车加速度的平均值和汽车加速度的最大值;步骤3、若0≤G≤β,则该驾驶员驾驶风格为舒适型;若β<G≤100%,则该驾驶员驾驶风格为运动型;其中,β为驾驶员驾驶风格舒适型与运动型识别的临界值,G为驾驶员驾驶风格识别度;步骤4、通过驾驶员驾驶风格,得到换挡过程中驱动电机降扭速率、驱动电机调速速率和驱动电机扭矩恢复速率。本发明具有提升换挡智能化水平的特点。
