  • Patent number: 11623632
    Abstract: 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.

  • Patent number: 11370448
    Abstract: A vehicle control device is equipped with a travel control unit which, in the case that a user-requested driving force exceeds a system-required driving force in a state in which a user is not in contact with an operating element, performs a travel control on the basis of a limited driving force obtained by applying a limit to the user-requested driving force, whereas in the case that the user-requested driving force exceeds the system-required driving force in a state in which the user is in contact with the operating element, performs the travel control on the basis of the user-requested driving force without applying the limit to the user-requested driving force.

  • Publication number: 20210046921
    Abstract: A vehicle control device controls a vehicle including a first driving device and a second driving device having a maximum driving force that is smaller than a maximum driving force of the first driving device. The vehicle control device includes a control unit configured to, in a state where the vehicle is driven by a second driving force, if a determination unit determines that there is a step on the route of the vehicle, drive the vehicle by at least a first driving force.

  • Patent number: 10882390
    Abstract: Provided is a vehicle in which an internal combustion engine can be suitably assisted by a rotating electrical machine. The vehicle is provided with an internal combustion engine, a rotating electrical machine, a transmission, a clutch placed between the transmission and the combination of the internal combustion engine and rotating electrical machine, and a motive power control device that controls the motive power of the internal combustion engine and the rotating electrical machine. The motive power control device calculates additional motive power for the rotating electrical machine on the basis of the difference between the motive-power-transmitting capacity of the clutch and the motive power of the internal combustion engine.

  • Patent number: 10189345
    Abstract: In a vehicle, a first rotating electrical machine, is connected to first wheels via a clutch, and second rotating electrical machines are connected to second wheels or the first wheels without going through the clutch. A power control device allocates electric power to the second rotating electrical machines with higher priority over the first rotating electrical machine when adding additional power to power of an internal combustion engine, thereby generating power of the second rotating electrical machines with higher priority over power of the first rotating electrical machine.
