The invention discloses a pure electric vehicle transmission system control method and a pure electric vehicle. The pure electric vehicle transmission system control method comprises the steps that when the vehicle loosens an accelerator pedal in a driving mode or the vehicle loosens a brake pedal in a brake recovery mode; judging whether the vehicle enters a delay mode or not according to whether the brake pedal is stepped on or not, the depth change rate of the brake pedal, whether the accelerator pedal is stepped on or not, the depth change rate of the accelerator pedal, the current gear state and the current vehicle speed; if the vehicle enters the time delay mode, timing is started, and the time is the timing duration; meanwhile, the required pre-tightening torque of the vehicle is determined according to the current vehicle speed of the vehicle; the motor outputs required pre-tightening torque; and judging whether the vehicle exits the delay mode or not according to the timing duration, whether the brake pedal is treaded or not and whether the accelerator pedal is treaded or not. The method is simple in structure and high in control precision, can effectively improve the phenomenon that the vehicle generates abnormal sound in the torque sudden change process of the vehicle, improves the driving comfort, and improves the safety.
本发明公开了纯电车传动系控制方法及纯电车辆,该纯电车传动系控制方法包括:车辆在驱动模式下松开加速踏板或车辆在刹车回收模式下松开刹车踏板时,依据是否踩刹车踏板及刹车踏板深度变化率、是否踩踏加速踏板及加速踏板深度变化率、当前的挡位状态,以及当前的车速判断车辆是否进入延时模式;若车辆进入延时模式,则开始计时,为计时时长;与此同时,依据车辆当前的车速确定车辆的需求预紧扭矩;电机输出需求预紧扭矩;依据计时时长、是否踩刹车踏板以及是否踩踏加速踏板判断车辆是否退出延时模式。控制精度高,能够有效改善车辆在扭矩突变过程中造成的车辆产生异响的现象,提升了驾驶舒适度,提升了安全性。
