Hybrid vehicle engine state monitoring and fault handling method

The invention discloses a hybrid vehicle engine state monitoring and fault handling method. The hybrid vehicle engine state monitoring and fault handling method comprises the following steps that S10, a power assembly mode of a hybrid vehicle is set up; S20, an engine operating state is built, and an engine fault state is determined; and S30, a corresponding fault handling method is selected according to the identified engine fault state. According to the hybrid vehicle engine state monitoring and fault handling method of the embodiment, by setting up the vehicle power assembly mode, the power assembly operating state is specified, meanwhile the engine operating state and the engine fault state are built, the engine current conditions are classified, the current engine operating state and the fault state are accurately judged out in real time through the vehicle power assembly mode, an engine starting request, an engine rotating speed, engine torque, power motor torque and the like, and then corresponding fau
