ELECTRIC DEVICE CONTROL METHOD AND ELECTRIC DEVICE

In an electric device control method and an electric device according to the present invention, when the generation of electric power is carried out by a first electric motor receiving drive torque of an internal combustion engine that is rotatably supported relative to a drive shaft of a hybrid vehicle, the rotational speed of the internal combustion engine is set higher as the speed of the vehicle increases, and when the driving force required by a second electric motor that is connected to the drive shaft becomes zero or negative, if the vehicle speed is greater than or equal to a first threshold value, the internal combustion engine is stopped; and if the vehicle speed is less than the first threshold value, the power generation is continued.
