The invention discloses a remote control method for electric vehicle driving speed. The remote control method comprises the steps that a server receives positioning information, sent by an electric vehicle remote communication terminal T-Box, of the electric vehicle and the current driving speed of the electric vehicle; comparing the electric vehicle positioning information with the road map information to determine the road characteristics of the road section where the current position of the electric vehicle is located, wherein the road characteristics comprise static road characteristics and dynamic road characteristics; adjusting the speed limit value of the electric vehicle on the current driving road section in real time according to the road characteristics; and sending the speed limit value to the T-Box so that the controller of the electric vehicle can control the current driving speed of the electric vehicle according to the speed limit value. With application of the method,the dynamic speed limiting function is added to the electric vehicle, the speed of the electric vehicle is effectively controlled and the probability of traffic accidents is reduced.

    本申请公开了一种电动车行车速度的远程控制方法,包括:服务器接收电动车远程通信终端T‑Box发送的电动车的定位信息、电动车当前行驶速度。将电动车定位信息与道路地图信息进行对比,确定电动车当前位置所处路段的道路特征。道路特征包括静态道路特征、动态道路特征。根据道路特征,实时调整电动车在当前行驶路段的限速值。将限速值发送给T‑Box,以便电动车的控制器根据限速值控制电动车的当前行驶速度。本申请通过上述方法使电动车增加了动态限速功能,实现了电动车车速的有效控制,同时降低了交通事故发生的几率。
