The invention relates to a vehicle speed control method, device and system for remote driving. The method comprises the following steps: acquiring position information of obstacles around a vehicle detected by a vehicle end; comparing the position information of the obstacle with a dangerous area corresponding to the current speed of the vehicle, and judging whether the position information of the obstacle is located in the dangerous area or not, wherein the range of the dangerous area is correspondingly adjusted according to the current vehicle speed and the corresponding braking time; and when the position information of the obstacle is determined to be located in the dangerous area, sending a deceleration signal to the vehicle end so that the vehicle end reduces the current vehicle speed according to the deceleration signal. According to the scheme provided by the invention, the cloud can adjust the speed of the vehicle in time according to the judgment result so that the controlled vehicle is prevented from colliding with the obstacle, and the traffic safety problem caused by collision with the obstacle is prevented.
本申请涉及一种远程驾驶的车速控制方法、装置及系统。该方法包括:获取来自车端检测的车辆周围的障碍物的位置信息;将障碍物的位置信息与车辆的当前车速对应的危险区域进行比较,判断障碍物的位置信息是否位于危险区域内;其中,危险区域的范围根据当前车速及对应的制动时间对应调整;当确定障碍物的位置信息位于危险区域内时,发送减速信号至车端,以使车端根据减速信号降低当前车速。本申请提供的方案,云端可以及时根据判断结果来调整车辆的车速,从而避免被控车辆碰撞障碍物,防止因碰撞障碍物而产生的交通安全问题。
