Patent number: 11623632Abstract: A vehicle control device includes a control unit. In a state where a first electric motor generates electricity by rotating an internal combustion engine and a target driving force is decided based on an operation for an accelerator pedal, the control unit performs a first driving control in which driving of a vehicle by a first driving force, which is a driving force of a first driving device including the internal combustion engine and the first electric motor, is prioritized. In a state where the first electric motor generates electricity by rotating the internal combustion engine and the target driving force is decided without being based on the operation for the accelerator pedal, the control unit performs a second driving control in which driving of the vehicle by a second driving force, which is a driving force of a second driving device including a second electric motor, is prioritized.Type: GrantFiled: August 13, 2020Date of Patent: April 11, 2023Assignee: Honda Motor Co., Ltd.Inventors: Atsuki Iwamitsu, Yuki Nakada, Takumi Kawano, Takaaki Kuwabara, Shigeki Kazehare

Patent number: 10029692Abstract: A vehicle drive system includes an internal combustion engine, a clutch, an engine rotation speed detector, an output shaft rotation speed detector, and a processor. The internal combustion engine includes cylinders and a crankshaft. The clutch is connected to the crankshaft via a torsion element and includes an output shaft. The engine rotation speed detector detects a crankshaft rotation speed. The output shaft rotation speed detector detects an output shaft rotation speed. The processor is configured to calculate a torque generated in each of the cylinders based on the crankshaft rotation speed. The processor is configured to decrease transmission torque of the clutch so that a difference between the crankshaft rotation speed and the output shaft rotation speed to be a target value when misfiring occurs. The processor is configured to identify a misfiring cylinder among the cylinders based on the torque calculated while the transmission torque is decreased.Type: GrantFiled: March 10, 2017Date of Patent: July 24, 2018Assignee: HONDA MOTOR CO., LTD.Inventors: Yasushi Nakoji, Takaaki Kuwabara, Takashi Hoshi
