The invention provides an electric vehicle speed limiting method and system, a readable storage medium and an electric vehicle, and the method comprises the steps: obtaining a speed limiting signal of the vehicle, and obtaining an induction distance between the vehicle and a target object in real time; when the sensing distance is within a first preset threshold value range, controlling a motor of the vehicle to be in a torque mode, and controlling the torque of the motor to be smaller than or equal to a preset torque threshold value; and when the sensing distance is within a second preset threshold value range, controlling a motor of the vehicle to be in a rotating speed mode, controlling the rotating speed of the vehicle to be a preset rotating speed threshold value, and the upper limit value of the second threshold value range is smaller than the lower limit value of the first threshold value range. The motor mode of the vehicle is determined according to the sensing distance between the vehicle and the target object, so that the vehicle is controlled to enter different motor modes corresponding to different sensing distances, the running speed of the vehicle is limited, and potential safety hazards caused by overspeed of the vehicle are avoided.

    本发明提供一种电动车辆限速方法、系统、可读存储介质及电动车辆,所述方法包括:获取所述车辆的限速信号,并实时获取所述车辆与所述目标物体之间的感应距离;当所述感应距离在第一预设阈值范围内时,控制所述车辆的电机为扭矩模式,且控制所述电机的扭矩小于或等于预设扭矩阈值;当所述感应距离在第二预设阈值范围内时,控制所述车辆的电机为转速模式,且控制所述车辆的转速为预设转速阈值,所述第二阈值范围的上限值小于所述第一阈值范围的下限值。本发明根据车辆与目标物体之间的感应距离来决定车辆的电机模式,以控制所述车辆进入不同的感应距离所对应的不同的电机模式,从而达到限制车辆的行驶速度,避免因车辆超速带来的安全隐患。
