The invention relates to the technical field of engine starting and stopping, and discloses a method and device for controlling starting and stopping of a vehicle engine, an automobile and a storage medium, and the method comprises the steps that under the condition that the automobile is in a braking static state, static road condition information and dynamic road condition information around the automobile are obtained based on a high-precision map module preloaded on the automobile; and on the basis of the dynamic road condition information and the static road condition information around the vehicle, the start-stop state of a vehicle engine is controlled. According to the method, the start-stop control of the vehicle engine adapts to the driving road condition of the vehicle, so that the situation that the engine is shut down in the scene that a user does not need to shut down due to simple start-stop judgment conditions is avoided, the start-stop function of the vehicle is more intelligent, and the driving experience of the user is improved; in addition, fuel economy control can be conducted on starting and stopping of the engine according to road conditions, the engine is prevented from being shut down in some scenes not beneficial to the fuel economy, and the fuel economy of the engine is truly achieved.

    本发明涉及发动机启停技术领域,公开了一种用于控制车辆发动机启停的方法、装置、汽车及存储介质,该方法包括:在车辆处于刹停静止状态的情况下,基于车辆上预载的高精度地图模块,获取车辆周围的静态路况信息和动态路况信息;基于车辆周围的动态路况信息和静态路况信息,控制车辆发动机的启停状态。本公开使得车辆发动机的启停控制与车辆的行驶路况相适应,从而避免了因为启停判断条件简答而导致发动机在用户不需要关停场景下被关停的情况,让汽车启停功能更加智能,提高了用户的驾驶体验;此外,车辆还能够根据路况对发动机启停进行燃油经济性控制,防止在一些不利于燃油经济性场景下关停发动机,正真做到了发动机的燃油经济性。
