The invention relates to the technical field of vehicle control, and discloses a hybrid vehicle engine control method and device, a hybrid vehicle, a medium and a program.The hybrid vehicle engine control method comprises the steps that when the vehicle runs in a hybrid power mode, the temperature of cooling liquid of a vehicle engine is monitored in real time, and the current remaining electric quantity of a vehicle battery is obtained; if it is detected that the temperature of the cooling liquid is larger than a first temperature threshold value and the duration time is larger than a first time threshold value, based on the current remaining electric quantity, a corresponding mileage threshold value of the vehicle in a pure electric mode is determined, an engine is controlled to stop, and the stop time of the engine and the pure electric mileage of the vehicle after the engine stops are recorded; and if it is detected that the shutdown time of the engine is larger than the second time threshold value or the pure electric driving mileage reaches the driving mileage threshold value, the engine is controlled to be started, so that engine cylinder rushing damage caused by cooling liquid overtemperature faults is avoided, the service life of the engine is prolonged, and the maintenance cost is greatly reduced.

    本发明涉及车辆控制技术领域,公开了混动车辆发动机控制方法、装置、混动车辆、介质及程序,包括:在车辆运行在混合动力模式下时,实时监测车辆发动机的冷却液温度,并获取车辆电池的当前剩余电量;若检测到冷却液温度大于第一温度阈值且持续时间大于第一时间阈值,基于当前剩余电量,确定车辆在纯电模式下对应的行驶里程阈值,并控制发动机停机,记录发动机停机时间以及车辆在发动机停机后的纯电行驶里程;若检测到发动机停机时间大于第二时间阈值或纯电行驶里程达到行驶里程阈值,控制发动机启动,从而避免冷却液超温故障导致的发动机冲缸损坏,有利于延长发动机的使用寿命,大大降低了维修成本。
