The invention provides an engine misfire processing method and a hybrid vehicle, and the method comprises the steps: responding to a misfire processing request signal through a vehicle control unit, and executing a misfire processing strategy; the misfire treatment strategy comprises the steps that whether the current rotating speed of the engine is within a preset resonance rotating speed interval or not is judged; and if the current rotating speed of the engine is within the preset resonance rotating speed interval, the rotating speed of the engine is adjusted, so that the engine runs at the rotating speed avoiding the preset resonance rotating speed interval. According to the engine misfire treatment method, the engine does not resonate with the power assembly system when the engine misfire phenomenon occurs, the vehicle can be protected, and the riding experience of a user can be improved.

    本申请提供一种发动机失火的处理方法、混合动力车辆,所述方法包括:通过所述整车控制器响应于失火处理请求信号,执行失火处理策略;其中,所述失火处理策略包括:判断所述发动机的当前转速是否处于预设共振转速区间内;以及,若所述发动机的当前转速处于所述预设共振转速区间内,则调节所述发动机的转速,使得所述发动机以避开所述预设共振转速区间的转速来运行。本申请提供的发动机失火的处理方法能够让发动机在出现失火现象时不与动力总成系统共振,不仅能够对车辆起到保护作用,还能够提升用户的乘坐体验。
