Abstract

A parking assistance apparatus has a region detector capable of detecting a plurality of possible parking regions where a vehicle can park in at least one side to the left or right of the vehicle, a photographic image of the scenery surrounding the vehicle including the possible parking regions is displayed on a monitor device, the possible parking regions detected by the region detector are superimposed on the photographic image as graphic images showing parking target candidates in all of the corresponding positions, and one of the parking target candidates can be selected as a parking target on the basis of a command input from a driving device of the vehicle.

Claims

1. A parking assistance apparatus comprising:

a region detector capable of detecting a plurality of possible parking regions in which a vehicle can park in at least one side to the left or right of the vehicle;

photographic image acquisition part for acquiring a photographic image of the scene surrounding the vehicle;

a display controller for displaying the photographic image on a monitor device and superimposing graphic images showing parking target candidates in positions where the possible parking regions detected by the region detector correspond on the photographic image; and

a selection part capable of selecting one of the parking target candidates as a parking target on the basis of command input from a driving device of the vehicle,

wherein

the driving device is a steering device of the vehicle, and

the selection part selects as the parking target a parking target candidate in a position that is nearer to the vehicle when, based on an operated amount of the steering device, the operated amount is greater.

2. The parking assistance apparatus according to claim 1, wherein the selection part is capable of selecting one of a plurality of the parking target candidates as the parking target in at least one side to the left or right of the vehicle.

3. The parking assistance apparatus according to claim 1, wherein the selection part selects, as the parking target, the parking target candidate located in the steering direction of the steering device.

4. The parking assistance apparatus according to claim 3, wherein a photographic image displayed in the monitor device is a photographed image of the rear of the vehicle reflected left-to-right as in a mirror, and one of the parking target candidates superimposed on the photographic image is selected as the parking target.

5. The parking assistance apparatus according to claim 1, wherein the selection part, when the region detector has detected the possible parking regions to both the left and right of the vehicle, selects as the parking target the parking target candidate in the direction corresponding to the steering direction of the steering device from among the parking target candidates corresponding to the detected possible parking regions.

6. The parking assistance apparatus according to claim 1, wherein the operated amount of the steering device when the parking target is selected is treated as an initial steering angle during guidance along a parking route to the parking target.
