The invention discloses an electric vehicle creeping control method. The method specifically comprises the following steps: S1, based on a received creeping signal, detecting whether an electric vehicle currently meets a creeping enabling condition or not; and S2, if so, recognizing expected actions of the driver based on the change rate of a brake pedal, and controlling output of the creeping torque based on the expected actions, wherein the expected actions include rapid braking, creeping deceleration, creeping acceleration, parking and constant-speed creeping. The creeping driving torque isassociated with the stroke of the brake pedal, so that the driver can well control the vehicle speed in a half-brake state; and by changing the change rate of the brake pedal, the control intention of the driver can be accurately recognized, and the driving experience is improved.
本发明公开了一种电动车蠕行控制方法,该方法具体包括如下步骤:S1、基于接收到的蠕行信号,检测电动车当前是否满足蠕行使能条件;S2、若检测结果为是,基于刹车踏板的变化率来识别驾驶员的期望动作,基于期望动作来控制蠕行扭矩的输出,所述期望动作包括:快速制动、蠕行减速、蠕行加速、停车及定速蠕行。将蠕行驱动扭矩与刹车踏板行程相关联,使驾驶员在半刹车状态下也能很好控制车速;通过对刹车踏板变化率的变化,能够准确识别驾驶员的控制意图,提升驾驶体验。
