The invention discloses a hybrid power vehicle, an engine starting method and device thereof and a storage medium, and the method comprises the steps that when it is detected that the vehicle currently meets a driving motor reverse dragging condition, a motor target gear is sent to a transmission controller, wherein the motor target gear is used for indicating a transmission controller to control a transmission executing mechanism to engage a motor reverse dragging gear; and when it is judged that the current motor gear is the motor reverse dragging gear and the clutch state is closed, the driving motor is controlled to load the motor torque to reversely drag the engine. According to the method, the engine can be rapidly and stably started, the problems that a BSG starting belt is prone to breakage, low in transmission efficiency and poor in reliability are solved, the cost is reduced, and the system reliability is improved.

    本申请公开了一种混合动力车辆及其发动机起动方法、装置和存储介质,其中,方法包括:在检测到车辆当前满足驱动电机反拖条件时,向变速器控制器发送电机目标挡位;其中,电机目标挡位用于指示变速器控制器控制变速器执行机构挂电机反拖挡位;在判断当前电机挡位为电机反拖挡位,且离合器状态为闭合时,控制驱动电机加载电机扭矩进行反拖发动机。该方法可快速平稳地起动发动机,规避了BSG起动皮带易断裂、传递效率低、可靠性差的问题,降低了成本,提高了系统可靠性。
