The invention relates to the technical field of intelligent network connection automobiles, and discloses a vehicle speed planning method and device considering the influence of traffic lights in a vehicle following scene and a medium, and the method comprises the steps: obtaining the time sequence data of a front vehicle, and predicting the vehicle speed of the front vehicle at the next moment through a speed prediction model; establishing a traffic light decision model according to the state information of the vehicle and the traffic light information, and obtaining the state of the vehicle passing through the next traffic light; the safety, comfort and economical efficiency of the vehicle are comprehensively considered through the model prediction controller, the speed of the vehicle is planned according to the output result of the traffic light decision model, the state information of the vehicle and the road information, and the optimal speed of the vehicle when the vehicle safely passes through the traffic light or is safely parked in front of the traffic light is obtained. By comprehensively considering the influence of the previous vehicle information and the traffic light information, the optimal vehicle speed of the vehicle is planned, so that the vehicle can safely pass through the traffic light along with the vehicle, and the economical efficiency and comfort of the vehicle are further improved.

    本发明涉及智能网联汽车技术领域,公开了跟车场景下考虑交通灯影响的车速规划方法、设备及介质,方法包括:获取前车的时间序列数据,通过速度预测模型预测前车下一时刻的车速;根据自车的状态信息和交通灯信息建立交通灯决策模型,并得到自车通过下一个交通灯的状态;通过模型预测控制器综合考虑车辆的安全性、舒适性和经济性,根据交通灯决策模型输出的结果、自车的状态信息以及道路信息对自车的车速进行规划,得到自车安全通过该交通灯或自车安全停在该交通灯前的最优车速。通过综合考虑前车辆信息和交通灯信息的影响,规划得到车辆的最优车速,使车辆能够安全跟车通过交通灯,并进一步提升车辆的经济性和舒适性。
