  • Patent number: 11097625
    Abstract: A vehicle includes a battery, an electric power acquirer, a power supply unit, first and second relays, and a controller. The first relay connects and disconnects the battery to and from a power supply line. The second relay connects and disconnects the electric power acquirer to and from the power supply line. The controller executes a first switching control including switching the second relay to a connected state with the first relay kept in a connected state. In the switching of the second relay to the connected state in the first switching control, the controller reduces a difference between a potential of the second relay on the side on which the electric power acquirer is disposed and a potential of the second relay on the side on which the battery is disposed, using electric power inputted from the electric power acquirer.

  • Publication number: 20210083723
    Abstract: A vehicle control apparatus is to be provided in a vehicle including a wireless charger that charges a mobile device placed on the wireless charger. The vehicle control apparatus includes an interruption detector, a cause determination unit, and a notification controller. The interruption detector detects interruption of charging of the mobile device by the wireless charger, based on an operating state of the wireless charger. The cause determination unit determines whether a cause of the interruption of the charging is a first or second cause. The first cause is that the mobile device is moved by inertia during traveling. The second cause is that the mobile device is moved by a passenger. When the cause is determined as being the first cause, the notification controller notifies information about the interruption of the charging in a more prominent manner than when the cause is determined as being the second cause.

  • Publication number: 20210039645
    Abstract: A vehicle includes a controller and an operating unit. The controller controls an automatic vehicle hold (AVH) system maintaining the brake of the vehicle even after an operation of the brake pedal is canceled, and an idling stop system (ISS) stopping idling of an internal combustion engine. The operating unit switches the AVH and ISS between an enabled state and a disabled state in response to an occupant's operation. When the vehicle comes to a stop, the controller activates the AVH in a case where the operation of the brake pedal satisfies a first operation condition, and activates the ISS in a case where the operation of the brake pedal satisfies a second operation condition. The controller changes at least one of the first operation condition or the second operation condition when the AVH and the ISS are both switched to the enabled state by the operating unit.

  • Publication number: 20210031748
    Abstract: A vehicle control apparatus includes a controller that switches a vehicle between an HEV traveling mode and an EV traveling mode. When the output current of a DC-to-DC converter becomes equal to or higher than a threshold, the controller decreases the output current by decreasing the output voltage of the DC-to-DC converter through output regulation control. The controller makes switching between a normal setting in which the threshold for the output regulation control is set to a reference threshold and a boost setting in which the threshold is set to a boost threshold higher than the reference threshold. The controller prohibits the boost setting when a power margin for boosting becomes equal to or lower than a first power margin value in the HEV traveling mode and when the power margin for the boosting becomes equal to or lower than a second power margin value in the EV traveling mode.

  • Publication number: 20210009000
    Abstract: An electric vehicle includes a power receiver, a controller, an error detector, and a record processor. The power receiver wirelessly receives electric power from power transmission equipment disposed outside the vehicle. The controller controls the reception of the electric power via the power receiver. The error detector detects an error in power transmission from the power transmission equipment to the power receiver during the control of the reception of the electric power by the controller. The record processor records error history information regarding the error detected by the error detector and causes a data volume of the error history information retrievable from the record processor to be smaller when the error is due to a foreign object present between the power transmission equipment and the vehicle than when the error is not due to the foreign object.
