The invention discloses a vehicle, an engine control method and device of the vehicle, a storage medium and a whole vehicle controller, the vehicle comprises a range extender, an engine is applied to the range extender, the range extender further comprises a generator, and the starting control method of the vehicle engine comprises the steps that when the vehicle meets the range extending requirement, the starting target rotating speed and the ignition rotating speed of the engine are obtained; and controlling the generator to drag the engine to perform multi-stage acceleration according to the starting target rotating speed and the ignition rotating speed until the rotating speed of the engine is the starting target rotating speed. Therefore, the rotating speed of the engine can quickly reach the ignition rotating speed and slowly rise to the highest starting rotating speed, so that the starting efficiency is improved, the starting smoothness is improved, the noise, vibration and sound vibration roughness performance of the whole vehicle is effectively improved, and more comfortable and cheerful driving experience is brought to a driver.

    本发明公开了一种车辆及其发动机控制方法和装置、存储介质、整车控制器,其中,车辆包括增程器,发动机应用于增程器,增程器还包括发电机,车辆发动机的启动控制方法包括:在车辆满足增程需求时,获取发动机的启动目标转速和点火转速;根据启动目标转速和点火转速控制发电机拖动发动机进行多段加速,直至发动机的转速为启动目标转速。由此,可以使发动机的转速快速达到点火转速,且平缓的上升至最高启动转速,从而提高启动效率,以及提升了启动平顺性,并有效改善了整车的噪音、振动与声振粗糙度性能,为驾驶者带来更加舒适与愉悦的驾乘体验。
