The embodiment of the invention provides a vehicle control method, device and equipment and a medium, relates to the technical field of intelligent driving, and can be used for scenes such as ports, mines, expressways and urban traffic. The method comprises the steps that according to the current position and the driving route of a vehicle, the target gradient at the set distance in front of the current position on the driving route is obtained from a high-precision map, the gradient in front can be determined in advance, and the driving speed of the vehicle is determined according to the corresponding relation between the gradient stored in advance and the driving speed. The first target driving speed is rapidly determined in a query mode, the calculation process is omitted, the time delay is lower, the response is faster, the timeliness of vehicle speed determination is ensured, the target gradient in front of the driving route is obtained in advance, vehicle speed control is carried out, and the vehicle speed control efficiency is improved. Therefore, the control accuracy can be ensured to a certain extent.

    本申请实施例提供了一种车辆控制方法、装置、设备及介质,涉及智能驾驶技术领域,可用于港口、矿山、高速、城市交通等场景。该方法包括:根据车辆的当前位置及行驶路线,从高精地图中获取该行驶路线上的当前位置的行驶前方设定距离处的目标坡度,可以提前确定前方的坡度,并通过预先保存的坡度与行驶车速的对应关系,通过查询的方式快速确定第一目标行驶车速,省去了计算过程,时延更低,响应更加快速,从而保证车速确定的及时性,并且本申请实施例中预先获取了行驶路线上行驶前方的目标坡度,从而进行车速控制,因此可以从一定程度上保证控制的准确性。
