While the residual distance D is longer than a second distance D2 shorter than the first distance after becoming equal to or shorter than the first distance, the parking support apparatus allows the vehicle to travel at a second speed V2 lower than the first speed. After the residual distance D becomes equal to or shorter than the second distance D2, the parking support apparatus allows the vehicle to travel at a third speed V3 lower than the second speed V2. When the vehicle reaches a prescribed position in the parking section, or when determining that the wheel of the vehicle reaches the wheel stopper, the parking support apparatus stops the traveling of the vehicle to end the parking support control.SELECTED DRAWING: Figure 12
