The invention relates to a speed limiting method and device of an electric vehicle, a vehicle and a storage medium, and the method comprises the steps that voice information of a user or triggering information of a speed limiting key is received; a speed limiting instruction of the vehicle is generated according to the voice information or the triggering information, a speed limiter of the vehicle is started in response to the speed limiting instruction, and a target speed limiting value of the vehicle is obtained according to the speed limiting instruction; and under the condition that the current speed of the vehicle reaches the target speed limit value, the speed of the vehicle is limited according to the speed limit torque, so that the vehicle is controlled to run at the target speed. According to the embodiment of the invention, the speed of the vehicle can be limited according to the speed limiting torque under the condition that the current speed of the vehicle reaches the target speed limiting value, so that the vehicle is effectively controlled to run at the target speed. According to the embodiment of the invention, all-road-condition self-adaptive speed limiting can be realized, so that a driver does not need to pay attention to overspeed during driving, the fatigue degree of the driver is relieved, and the sense of safety of the driver and passengers is improved.

    本申请涉及一种电动汽车的限速方法、装置、车辆及存储介质,其中,方法包括:接收用户的语音信息或者限速按键的触发信息;根据语音信息或者触发信息生成车辆的限速指令,并响应于限速指令,启动车辆的限速器,并根据限速指令得到车辆的目标限速值;在车辆的当前车速达到目标限速值的情况下,根据限速扭矩对车辆进行限速,以控制车辆维持在目标车速行驶。本申请实施例可以在车辆的当前车速达到目标限速值的情况下,根据限速扭矩对车辆进行限速,从而有效控制车辆维持在目标车速行驶。本申请实施例可以全路况自适应限速,使驾驶员在行车时不必时刻关注车速超速,减轻了驾驶员的疲劳程度,提升了驾驶员和乘客的安全感。
