Patent number: 12090990Abstract: It is determined whether fuel efficiency of a vehicle is improved by operating a first rotating machine to generate electricity to such an extent that an electrical path amount becomes a desired electrical path amount for controlling an operating point of an engine to a desired operating point and driving and operating a second rotating machine as a second power source, the electrical path amount being a magnitude of electric power in an electrical path through which the electric power is transferred between the first rotating machine and the second rotating machine. When the electronic control device determines that the fuel efficiency of the vehicle is improved, the first rotating machine is operated to generate electricity to such an extent that the electrical path amount becomes the desired electrical path amount and the second rotating machine is driven and operated as the second power source.Type: GrantFiled: April 20, 2022Date of Patent: September 17, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Atsushi Tabata, Koichi Okuda, Koji Takaira, Tatsuya Imamura, Yohei Habata
