The invention provides a speed control technology for an electric vehicle in a crawling state, the electric vehicle is driven by a driving motor, and a control unit comprises a control module for controlling the vehicle to run in a forward gear or a reverse gear, a judgment module for judging whether the vehicle is in the crawling state or not, and a checking module for checking the current running gear of the vehicle. The storage module is used for storing a preset forward gear maximum speed value DV and a preset reverse gear maximum speed value RV, and the DV is larger than the RV. The problem that the crawling speed is the same when the electric vehicle advances and retreats is solved.

    本申请提供一种电动车辆蠕行状态的速度控制技术,所述电动车辆通过驱动电机驱动,所述控制单元包括控制车辆以前进挡或后退挡运行的控制模块,及判断车辆是否处于蠕行状态的判断模块,及检查车辆当前行驶挡位的检查模块,及存储预设的前进挡最大速度值DV及后退挡最大速度值RV的存储模块,其中DV大于所述RV。以解决电动车辆在前进和后退时蠕行速度相同的问题。
