The invention discloses a starting method and device of a hybrid power engine, a vehicle and a medium, and relates to the technical field of vehicles. The method comprises the steps that whether the vehicle enters an emergency state or not is judged; the emergency state represents that the vehicle cannot enter a high-voltage working state; under the condition that it is confirmed that the vehicle enters the emergency state, power is supplied to a high-voltage system of the vehicle based on a low-voltage storage battery of the vehicle; according to the low-voltage starting parameters, an engine of the vehicle is controlled to be started; wherein the low-voltage starting parameter is smaller than the high-voltage starting parameter; the low-pressure starting parameters represent parameters required for starting an engine in a low-pressure working state; the high-pressure starting parameters represent parameters required for starting the engine in a high-pressure working state. By adopting the method, the engine can be started through the electric quantity output by the low-voltage storage battery under the condition that the high-voltage battery cannot work normally.

    本发明公开了涉及车辆技术领域的一种混合动力发动机的启动方法、装置、车辆和介质,所述方法包括:判断车辆是否进入应急状态;所述应急状态表征所述车辆无法进入高压工作状态;在确认所述车辆进入所述应急状态的情况下,基于所述车辆的低压蓄电池向所述车辆的高压系统供电;根据低压启动参数,控制所述车辆的发动机启动;其中,所述低压启动参数小于高压启动参数;所述低压启动参数表征在低压工作状态下启动发动机需求的参数;所述高压启动参数表征在高压工作状态下启动发动机需求的参数。采用该方法能够在高压电池无法正常工作的情况下,通过低压蓄电池输出的电量启动发动机。
