1. A parking assistance apparatus comprising:
a relative-position-obtaining unit that obtains a relative position of a power-receiving unit that is mounted on a vehicle to a power-transmitting unit that transmits power to the power-receiving unit in a non-contact manner; and
a parking assistance control unit that implements parking assistance control for assistance in parking of the vehicle, based on the relative position, while adjusting the position of the power-receiving unit with respect to the power-transmitting unit,
wherein the parking assistance control unit comprises:
a first-range-determining unit that determines whether the power-receiving unit is within a first range in which the relative position of the power-receiving unit to the power-transmitting unit is obtainable,
a second-range-determining unit that determines whether the power-receiving unit is within a second range in which the power-receiving unit is positioned nearer than that in the first range to the power-transmitting unit when the first-range-determining unit determines that the power-receiving unit is within the first range,
a first assistance control unit that implements, when the first-range-determining unit determines that the power-receiving unit is within the first range, as the parking assistance control, first assistance control for controlling the vehicle such that a displacement of the vehicle per unit time is less than that in case where it is determined that the power-receiving unit is not within the first range, and
a second assistance control unit that implements, when the second-range-determining unit determines that the power-receiving unit is within the second range, as the parking assistance control, second assistance control for controlling the vehicle such that the displacement of the vehicle per unit time is less than that during implementing the first assistance control,
wherein the vehicle includes a brake device that outputs braking force of the vehicle in case where a driver of the vehicle performs a braking operation, and
wherein during implementing the second assistance control, the second assistance control unit controls the brake device such that an output ratio of the braking force with respect to the braking operation is higher than that during implementing the first assistance control.
