Patent number: 11427182Abstract: A control device for a hybrid vehicle is provided. When a first drive mode is selected as the drive mode of the hybrid vehicle, a control section shifts the drive mode to a second drive mode when a charge amount of a battery for an electric motor becomes smaller than or equal to a determination charge amount. The first drive mode operates the electric motor while an internal combustion engine is stopped. The second drive mode permits the operation of the internal combustion engine. The control section executes a shifting process when the upper limit system output is lower than or equal to a startup determination output even though the charge amount of the battery is greater than the determination charge amount. The shifting process shifts the drive mode to the second drive mode to start the internal combustion engine.Type: GrantFiled: March 11, 2020Date of Patent: August 30, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yohei Moriyama, Shigeki Nakayama, Ikuma Tsuzuki
