An electric device control method controls an electric device that includes an internal combustion engine, a first electric motor that receives a driving force of the internal combustion engine to carry out power generation, and a second electric motor connected to a drive shaft. The method sets a rotational speed of the internal combustion engine to increase as a vehicle speed of the vehicle increases while the power generation is carried out by the first electric motor. Where the driving force required by the second electric motor becomes zero or negative while the first electric motor is carrying out power generation by the driving force of the internal combustion engine, the internal combustion engine is stopped where the vehicle speed is greater than or equal to a first threshold value, and the power generation is continued where the vehicle speed is less than the first threshold value.
An electric device control method for controlling an electric device that includes an internal combustion engine of a vehicle, a generator configured receive a driving force of the internal combustion engine to carry out power generation, and a drive motor connected to a drive shaft that is rotatable relative to the internal combustion engine, the electric device control method comprising:

This application is a U.S. national stage application of International Application No. PCT/JP2019/023688, filed on Jun. 14, 2019.
The present invention relates to an electric device control method and an electric device.
Japanese Laid-Open Patent Application No. 8-317505 (Patent Document 1) discloses a hybrid vehicle that, when the accelerator is off and the remaining battery capacity is less than or equal to a prescribed value, carries out charging by continuing electric power generation by means of the drive torque of the engine.
Referring now to the attached drawings which form a part of this original disclosure.
FIG. 1 is a block diagram illustrating the configuration of a hybrid vehicle that includes the electric device according to one embodiment of the present invention.
FIG. 2 is a block diagram illustrating the functional constituent elements of a vehicle controller.
An embodiment of the present invention will now be described with reference to the drawings. In the description, the same elements have been designated by the same reference numerals, and redundant explanations have been omitted.
Configuration of the Electric Device
The configuration of a hybrid vehicle that includes an electric device according to the present embodiment will be described with reference to FIG. 1. The hybrid vehicle according to the present embodiment comprises an engine 1 (internal combustion engine), a generator 4 (first electric motor), a battery 5 (power storage device), a drive motor 6 (second electric motor), and wheels 7 (drive wheels). The wheels 7 of the hybrid vehicle are not driven by the engine 1, but rather the wheels 7 are driven by the drive motor 6 using electric power from the battery 5, and because the engine 1, the battery 5, the drive motor 6, and the wheels 7 are connected in series (series connection), the hybrid vehicle is called a series hybrid vehicle.
