  • Patent number: 10933801
    Abstract: A vehicle control device which at least partially automatically performs travel control of a vehicle includes processor(s) which diagnose failure of functions related to automated driving and to continue the automated driving with the functions partially stopped when a failure is diagnosed, and a light emission unit which provides notification to a surrounding of the vehicle by light emission that the vehicle is controlled in a fallback operation. The processor(s) detect an operation state of the light emission unit, permit execution of the automated driving when the light emission unit operates normally and prohibits the automated driving when the light emission unit does not operate normally.

  • Patent number: 10759333
    Abstract: A vehicle control device of the present invention at least partially automatically performs drive control for a vehicle by self-drive and is provided with: a hazard lamp for notification around the vehicle; and a light emitting control unit which, when a predetermined condition is satisfied during self-drive, performs light emitting control causing the hazard lamp to emit light. The light emitting control unit, as well as causing the hazard lamp to emit light, performs light emitting control whereby a lighting member, different from the hazard, for notification around the vehicle is caused to emit light when the hazard lamp is not normal.

  • Patent number: 10710606
    Abstract: An electric power supply apparatus for a vehicle includes a second switch for performing ON/OFF switching of electric power supply from a second power supply to a second control unit, a third switch for performing ON/OFF switching of a first drive signal to the second switch, and a switch control circuit for outputting a second drive signal to the second switch when predetermined conditions are satisfied. The second switch is turned on when the first drive signal or the second drive signal is input, and the second switch is turned off when the first drive signal and the second drive signal are not input.

  • Patent number: 10246124
    Abstract: An electric power steering device includes a main power supply unit capable of supplying power to a load; an auxiliary power supply unit connected to the main power supply unit and capable of supplying charged power to the load; a boosting circuit capable of boosting a voltage supplied from the main power supply unit and applying a resulting voltage to the auxiliary power supply unit; a circuit switching unit interposed between the main power supply unit and the load and closing one of a first connection circuit extending from the main power supply unit to the load and a second connection circuit extending from the main power supply unit to the load via the auxiliary power supply unit; and a controller performing switching control on the circuit switching unit so as to close the second connection circuit if the magnitude of power required by the load exceeds a first threshold.

  • Publication number: 20100211261
    Abstract: Provide is a vehicle behavior control system that can achieve a rear wheel steering control demonstrating a high rate of response at all times without requiring the actuator for the rear wheels to be steered to be unduly increased. A control unit (20) for controlling the rear wheel steering angle is configured to reduce the effective stiffness of the rear wheel suspension systems while increasing the effective stiffness of the front wheel suspension systems when an increase in the road contact load of one of the rear wheels is detected or estimated. Thereby, an actuator (8) for the rear wheel is enabled to steering the rear wheels without involving any undue time delay with a minimum power requirement.
