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.

Wireless power feeding control apparatus for vehicle and wireless charge system for vehicle

A vehicle includes a battery, an electric power acquirer, a power supply unit, first and second relays, a charging controller, and a first notification processor. The first relay connects the battery to a power supply line or disconnects the battery from the power supply line. The charging controller switches, on a request for charging of the battery with the first relay in a connected state, the first relay to a disconnected state, brings the second relay to a connected state, and switches the first relay to a connected state to start the charging of the battery. The first notification processor gives, on the request for the charging of the battery, a user a notification of temporary shutdown of the power supply unit at a start of the charging of the battery.

Vehicle

A control apparatus of a plug-in hybrid electric vehicle that is provided with a fuel tank, an engine, a battery, and an electric motor. The battery is chargeable by an external power source. The control apparatus includes a fuel deterioration determiner and a regeneration amount limiter. The fuel deterioration determiner determines whether a fuel stored in the fuel tank is deteriorated. The regeneration amount limiter reduces, when the fuel is determined by the fuel deterioration determiner as being deteriorated, a regeneration amount to be less than the regeneration amount of a case where the fuel is determined by the fuel deterioration determiner as not being deteriorated. The regeneration amount is an amount of regeneration of electric power generated by the electric motor upon deceleration of the plug-in hybrid electric vehicle.

Control apparatus of plug-in hybrid electric vehicle

A vehicle includes a battery, an electric power acquirer, a power supply unit, first and second relays, a controller, a vehicle controller, and a first determination unit. The first determination unit makes a determination, at a system start-up, as to whether or not a power receiving coil of the electric power acquirer is in position to be available for electric power reception from a power transmitting coil of ground facilities. The controller changes, at the system start-up, a switching procedure of the first relay and the second relay on the basis of a result of the determination of the first determination unit.

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.

A vehicle includes a battery, an electric power acquirer, a power supply unit, first and second relays, and a controller. The electric power acquirer acquires charging electric power from outside. The power supply unit is able to provide a power supply from the battery to a device other than a traveling motor. 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 changes a switching procedure of the first relay and the second relay, in accordance with a state of use of the power supply unit, at an end of charging of the battery through the electric power acquirer.
