The invention relates to the technical field of vehicle control, in particular to an intersection vehicle speed guiding method based on V2X, which comprises steps of judging a scene where the main vehicle HV is located, if the scene is the scene 1, calculating a recommended vehicle speed V1 according to the speed in the main vehicle BSM, and the stop line position, the lamp phase information and the remaining time information of the traffic light broadcast, enabling the main vehicle HV to pass through the traffic light intersection without stopping according to the recommended vehicle speed V1, and when only the main vehicle HV and the traffic light exist in the scene, judging that the current scene is the scene 1. When what is predicted is that the vehicle arrives at the stop line and is a red light, the recommended vehicle speed V1 is calculated according to the speed in the main vehicle BSM and the stop line position, the lamp phase information and the remaining time information broadcasted by the traffic light, a reasonable driving speed can be recommended to the vehicle, and the vehicle can pass through the traffic light intersection without stopping.
本发明涉及汽车控制技术领域,具体涉及一种基于V2X的交叉路口车速引导方法。判断主车HV所处场景;若场景为场景一,则根据主车BSM中的速度,以及红绿灯广播的停止线位置、灯相位信息、剩余时间信息,计算出推荐车速V1;主车HV根据推荐车速V1不停车通过红绿灯路口;当场景中只有主车HV和红绿灯时,判断当前场景为场景一。当预测到车辆到达停止线时为红灯时,根据主车BSM中的速度,以及红绿灯广播的停止线位置、灯相位信息、剩余时间信息,计算出推荐车速V1,可以为车辆推荐一个合理的行车速度,使得车辆可以不停车地通过红绿灯路口。
