The invention discloses a vehicle auxiliary driving decision-making method and device, terminal equipment and a storage medium, and the method comprises the steps: constructing a transverse safety potential energy field of a road through structured road information; determining a relative safe distance between the to-be-controlled vehicle and the front target vehicle through the vehicle speed information and the acceleration information of the to-be-controlled vehicle and the relative vehicle speed information of the to-be-controlled vehicle and the front target vehicle; and establishing a longitudinal safe potential energy field through the relative safe distance to determine a vehicle driving decision of the to-be-controlled vehicle according to the potential energy of the to-be-controlled vehicle in the potential energy field so as to perform auxiliary control on the to-be-controlled vehicle. Through the implementation of the invention, the relative relationship between the to-be-controlled vehicle and the front target vehicle and the road can be directly judged through the constructed safety potential energy field, so that the optimal driving decision of the to-be-controlled vehicle can be quickly determined, the traffic jam auxiliary function of the vehicle on the urban road is realized, and the driving safety of the vehicle is improved.
本发明公开了一种车辆辅助驾驶决策方法、装置、终端设备及存储介质,所述方法包括:通过结构化道路信息,构建道路的横向安全势能场;通过待控制车辆的车速信息和加速度信息,以及与前方目标车辆的相对车速信息,确定待控制车辆与前方目标车辆的相对安全距离;再通过相对安全距离,建立纵向安全势能场,以根据待控制车辆在势能场中的势能,确定待控制车辆的车辆驾驶决策,进而对待控制车辆进行辅助控制。通过实施本发明,能够直接通过构建的安全势能场判断待控制车辆与前方目标车辆和道路的相对关系,以快速确定最优的待控制车辆的驾驶决策,实现车辆在城市道路的交通拥堵辅助功能,从而提高了车辆的行驶安全性。
