The invention provides an engine starting control method and system, a vehicle and a storage medium, and the control method comprises the steps that according to a received sliding starting instruction, a gearbox is controlled to be switched to a preset gear; after the gearbox is switched to the preset gear, a clutch is controlled to slide and rub so as to drag an engine to rotate; and after the rotating speed of the engine reaches the starting rotating speed, the engine is controlled to enable oil injection ignition, so that the engine is started. According to the engine starting control method, due to the fact that no starting motor load exists, it can be guaranteed that the dangerous situation that a whole automobile control system is reset due to the starting motor load in the sliding starting and stopping process of a traditional automobile is avoided. Besides, the scheme provided by the invention does not involve any hardware change, can be realized only by performing software change on the gearbox and the engine, is low in cost and good in realizability, and is suitable for traditional automobiles and hybrid vehicles with various topological structures.

    本发明提供了一种发动机启动控制方法、系统、车辆和存储介质,所述控制方法包括:根据接收到的滑行启动指令,控制变速箱切换至预设档位;待所述变速箱切换至所述预设档位后,控制离合器进行滑磨以拖动发动机进行转动;待所述发动机的转速达到启动转速后,控制所述发动机使能喷油点火,以启动所述发动机。本发明提供的发动机启动控制方法由于没有启动电机负载,也能保证传统汽车在滑行启停过程不会因启动电机负载而发生整车控制系统重置的危险情况。另外,本发明提出的方案不涉及任何硬件更改,只需对变速箱以及发动机进行软件变更即可实现,成本低且可实现性好,适用于传统汽车以及各种拓扑结构的混动车辆。
