  • Patent number: 11584247
    Abstract: A wireless power feeding control apparatus for a vehicle includes a positioning unit and an examination unit. The vehicle is provided with a power receiving coil that wirelessly receives electrical power from a power transmitting coil of a power transmission facility, a parking lock mechanism, and a parking lock sensor that outputs an electrical signal corresponding to a locked state of a wheel established by the parking lock mechanism. The positioning unit positions the power transmitting coil or assists in positioning the power transmitting coil on the basis of a quantity of electricity generated by the power receiving coil receiving a magnetic field from the power transmitting coil subjected to weak excitation weaker than excitation during electrical power transmission. The examination unit checks the locked state of the wheel after the weak excitation is stopped and before the electrical power transmission is started.

  • Patent number: 11414078
    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.

  • Patent number: 11302937
    Abstract: The electric power supply control apparatus for a vehicle executes a driving prioritizing mode in which a supply of driving electric power is prioritized over a supply of temperature controlling electric power, and a temperature control prioritizing mode in which the supply of the temperature controlling electric power is prioritized over the supply of the driving electric power. While the modes are switched over, the apparatus controls the driving electric power or the temperature controlling electric power so that a sum of the powers stays at an upper limit value or smaller.

  • Patent number: 11247684
    Abstract: An electric power supply control apparatus for a vehicle decreases a first electric power prior to switching the modes, when a sum of a request value of a second electric power and the first electric power exceeds a total electric power upper limit value in the mode before the switching, and switches the modes after the sum of the decreased first electric power and the request value of the second electric power becomes equal to or smaller than the total electric power upper limit value.

  • Patent number: 11059385
    Abstract: There is provide an electric power supply control apparatus for a vehicle comprising a battery, an electric motor, and a temperature controller, the electric power supply control apparatus sets one of upper limit values of driving electric power and temperature controlling electric power at a predetermined value that is equal to or smaller than a total electric power upper limit value without being limited by the other one of the driving electric power and the temperature controlling electric power, and sets the upper limit value of the other one of electric power in a way such that a sum of the upper limit value of the other one of electric power and the one of electric power is equal to or smaller than the total electric power upper limit value.
