The embodiment of the invention provides a plug-in hybrid electric vehicle control method and system and a storage medium. The method comprises the steps that fuel oil liquid level data are obtained; in the operation process of the engine, when flameout of the engine is monitored based on the working condition information of the engine, if it is determined that the real-time fuel oil liquid level is larger than or equal to the preset low oil level based on the fuel oil liquid level data, a component fault processing flow is triggered, and the engine is requested to be started; in the operation process of the engine, when flameout of the engine is monitored based on the working condition information of the engine, if it is determined that no component fault exists and it is determined that the real-time fuel oil liquid level is smaller than the preset low oil level based on the fuel oil liquid level data, the fuel oil depletion fault processing flow is triggered, and starting of the engine is not requested any more. By implementing the method, fuel oil in the fuel tank can be utilized as much as possible, meanwhile, physical damage of the electric oil pump is avoided, and vehicle driving safety is guaranteed.

    本申请实施例提供的一种插电式混合动力汽车控制方法、系统及存储介质,该方法包括获取燃油液位数据;发动机运行过程中,在基于发动机工况信息监测到发动机熄火时,若基于燃油液位数据确定实时燃油液位大于或等于预设低油位,则触发部件故障处理流程,并请求启动发动机;发动机运行过程中,在基于发动机工况信息监测到发动机熄火时,若确定无部件故障、且基于燃油液位数据确定实时燃油液位小于预设低油位,则触发燃油耗尽故障处理流程,并不再请求启动发动机。该方法的实施能够尽可能多的利用燃油箱内的燃油的同时,避免电动油泵的物理损坏,保障车辆行驶安全。
