The invention relates to the technical field of hybrid vehicles, and discloses a hybrid vehicle engine limp control method and device, a vehicle and a medium, and the method comprises the following steps: carrying out limp fault diagnosis on the vehicle; when the vehicle has the limp fault, the engine is made to enter an engine limp state; monitoring the whole vehicle information, and judging whether the whole vehicle information triggers a preset fault reset condition or not; and when the whole vehicle information triggers a preset fault reset condition, the limp fault is reset, so that the engine enters the normal state from the engine limp state. The problem that normal running of the vehicle is affected by continuous limp of the engine is solved.

    本发明涉及混动车辆技术领域,公开了一种混动汽车发动机跛行控制方法、装置、车辆及介质,方法包括:对车辆进行跛行故障诊断;当车辆存在跛行故障时,令发动机进入发动机跛行状态;监测整车信息,并判断整车信息是否触发预设故障复位条件;当整车信息触发预设故障复位条件时,对跛行故障进行复位,以使发动机从发动机跛行状态进入发动机正常状态。本发明解决发动机持续跛行影响车辆正常行驶的问题。
