Abstract: A vehicle control device includes a main control device, a sub-control device, and a temperature detection unit. The main control device includes a recognition unit that recognizes a peripheral situation of a vehicle, a driving control unit that controls steering and acceleration/deceleration of the vehicle independently from an operation of a driver, and a mode determination unit that determines a driving mode of the vehicle. The sub-control device is capable of controlling the vehicle in place of the main control device. The temperature detection unit detects a temperature of a second battery that is different from a first battery supplying power to the main control device and supplies power to the sub-control device. The mode determination unit changes the driving mode of the vehicle from the second driving mode to the first driving mode when a temperature of the second battery is lower than a predetermined temperature.

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.

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.

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.
