Abstract: A vehicle 2 includes a power receiving unit 11 which receives electrical power sent from a power supply unit 4; a relative position acquisition unit 21 which acquires a relative position of the power receiving unit 11 relative to the power supply unit 4; and an alignment aid unit 22 which aids in alignment of the power receiving unit 11 relative to the power supply unit 4, by notifying to the driver of information relative to displacement of the power receiving unit 11 relative to the power supply unit 4, based on the relative position acquired by the relative position acquisition unit 21. The alignment aid unit 22 is switchable between a first notification which notifies the information relative to displacement by way of an image display device 12, and a second notification which notifies the information relative to displacement by way of a vehicle information presenting device 14.

Abstract: A parking aid system aids in alignment parking of a vehicle to a parking space. The vehicle includes: a power receiving unit which receives the electrical power for alignment by way of a power receiving coil; a voltage measuring unit which measures voltage of the power receiving coil; a coil type specifying unit which specifies a type of the power supply coil during the alignment parking; and an alignment aid unit which calculates a target position of the power receiving unit, based on a voltage measured value. The alignment aid unit, in a case of the type of the power supply coil being a DD-type coil, calculates the position of a first peak P1 in the voltage measured value when changing the relative position between the power supply unit and the power receiving unit, and then calculates the target position based on the position of the first peak P1.

Abstract: A relative position of a power receiving unit to a power transmitting unit, represented by alignment assistance information, is corrected through a distance corresponding to a display delay time ?t1 and a vehicle response delay time ?t2. The relative position of one unit to the other at time t=t0?(?t2+?t1) is corrected to the relative position taken when it is assumed that a vehicle moves through a correction distance ?P=?P1+?P2. Although a position of the power receiving unit is actually out of a chargeable area at each of the time t=t0?(?t2+?t1) and at time t=t0??t2, the alignment assistance information representing that the position of the power receiving unit is within the chargeable area is displayed on an image display device at the time t=t0??t2.

Abstract: A relative velocity vector V is obtained which represents a time-dependent change of a relative position of a power receiving unit to a power transmitting unit set as a reference. Whether a user of a vehicle intends to park the vehicle into a parking space is determined depending on whether a relative velocity vector V(?) after having been corrected in accordance with a steering angle ? of the vehicle is oriented toward the parking space. Parking assistance information is displayed on an image display device in accordance with an estimation result that the user of the vehicle intends to park the vehicle into the parking space.

Abstract: When a vehicle is parked while the position of a power-receiving unit with respect to a power-transmitting unit is adjusted, an ECU in a parking assistance apparatus implements first assistance control if it is determined that the power-receiving unit is within a first range and implements second assistance control for controlling the vehicle such that a displacement of the vehicle per unit time is less than that during the first assistance control if it is determined that the power-receiving unit is within a second range.

Abstract: A displacement of a foreign object is detected on the basis of a position of the foreign object at each of a starting time and a finishing time of a predetermined period. By delaying the timing for determining the displacement mode of the foreign object by the predetermined period (predetermined time), the timing for providing notification recommending the removal of the foreign object can be delayed. When after it is determined that displacement of the foreign object present around a power transmitting unit is present, the presence of the foreign object is not detected, that is, in a state where it is not necessary to provide the notification recommending that a user remove the foreign object, that notification is omitted.

Abstract: A vehicle includes a high-voltage battery, a vehicle-mounted charger, an inlet, a charging ECU that controls the vehicle-mounted charger, and a parking lock mechanism that causes a rotation shaft to enter the rotation capable state or the rotation incapable state. The rotation shaft is provided for a gearbox which transmits driving power to the driving wheels.
