The embodiment of the invention discloses an electric vehicle single pedal control method and device. The method comprises steps that the current speed of an electric vehicle at a current moment and the current pedal opening degree of a single pedal are obtained when a single pedal mode is detected to be activated; based on a preset torque corresponding table, the target torque corresponding to the current vehicle speed and the current pedal opening degree is determined, the preset torque corresponding table comprises the corresponding relation among the vehicle speed, the pedal depth and thetorque, and the target torque is driving torque or braking torque; and when the target torque is the braking torque, a target braking mode is determined based on the target torque, and the target braking mode is an electric braking mode and/or a mechanical braking mode. According to the method, different target torques can correspond to different braking modes, the situation that the feeling of adriver is poor due to electric braking is avoided, gentle and stable braking process can be guaranteed, and driving feeling of the driver is improved.

    本说明书实施例公开一种电动车单踏板的控制方法及装置,所述方法包括:在检测到单踏板模式被激活时,获取当前时刻电动车的当前车速以及单踏板的当前踏板开度;基于预设的扭矩对应表,确定与当前车速以及当前踏板开度对应的目标扭矩,预设的扭矩对应表中包括车速、踏板深度以及扭矩之间的对应关系,目标扭矩为驱动扭矩或制动扭矩;在目标扭矩为制动扭矩时,基于目标扭矩,确定目标制动方式,目标制动方式为电制动方式和/或机械制动方式。上述方案中,不同的目标扭矩可以对应不同的制动方式,避免了仅由电制动造成了驾驶员感受较差,能够保证制动过程的平缓稳定,改善了驾驶员的驾驶感受。
