The invention provides a method and a device for controlling the maximum speed limit of an electric vehicle. The method and the device are used for setting the maximum speed limit of the vehicle by a user. The control method comprises the following steps: setting the maximum speed limit based on user selection when the vehicle is static; acquiring the current running speed of the vehicle; adjusting the maximum output torque coefficient of the vehicle based on the relationship between the current driving speed of the vehicle and the maximum speed limit; and controlling the current maximum output torque of the vehicle to be the product of the factory maximum output torque and the maximum output torque coefficient.

    本发明提供了一种电动汽车最高限速的控制方法及装置,用于由用户自行设置车辆的最高限速,控制方法包括:在车辆静止时基于用户选择设定最高限速;获取车辆当前行驶速度;基于车辆的当前行驶速度与最高限速之间的关系,调节车辆的最大输出扭矩系数;以及控制车辆当前的最大输出扭矩为出厂最大输出扭矩乘以最大输出扭矩系数。
