Abstract

A parking assist device comprises an image obtaining portion for obtaining a surrounding image of a vehicle, a display controlling portion for displaying the surrounding image and a pair of vehicle width extended lines on a displaying device provided at an interior of the vehicle in such a way that the pair of vehicle width extended lines is superposed on the surrounding image, the vehicle width extended lines serving as indicative lines for notifying a driver of a width of the vehicle and a stall line detecting portion for detecting a pair of stall lines indicating a parking stall, wherein, when the pair of the stall lines is detected, the display controlling portion changes a distance between the vehicle width extended lines corresponding to a distance between the stall lines.

Claims

1. A parking assist device comprising:

an image obtaining portion for obtaining a surrounding image of a vehicle, the surrounding image captured by an imaging device provided at the vehicle;

a display controlling portion for displaying the surrounding image and a pair of vehicle width extended lines on a displaying device provided at an interior of the vehicle in such a way that the pair of vehicle width extended lines is superposed on the surrounding image, the vehicle width extended lines serving as indicative lines for notifying a driver of a width of the vehicle; and

a stall line detecting portion for detecting a pair of stall lines in the surrounding image, the stall lines indicating a parking stall;

wherein, when the pair of the stall lines is detected by the stall line detecting portion, the display controlling portion changes a distance between the vehicle width extended lines corresponding to a distance between the stall lines.

2. The parking assist device according to claim 1, wherein the display controlling portion changes the distance between the vehicle width extended lines in a case where the distance between the stall lines is greater than the width of the vehicle.

3. The parking assist device according to claim 1, wherein a distance between outer sides of the vehicle width extended lines is set to the distance between the vehicle width extended lines, and a distance between inner sides of the stall lines is set to the distance between the stall lines.

4. The parking assist device according to claim 2, wherein a distance between outer sides of the vehicle width extended lines is set to the distance between the vehicle width extended lines, and a distance between inner sides of the stall lines is set to the distance between the stall lines.

5. The parking assist device according to claim 1, wherein the display controlling portion displays a pair of vehicle width elongated lines indicating the width of the vehicle, together with the vehicle width extended lines so as to be superposed on the surrounding image.

6. The parking assist device according to claim 2, wherein the display controlling portion displays a pair of vehicle width elongated lines indicating the width of the vehicle, together with the vehicle width extended lines so as to be superposed on the surrounding image.

7. The parking assist device according to claim 3, wherein the display controlling portion displays a pair of vehicle width elongated lines indicating the width of the vehicle, together with the vehicle width extended lines so as to be superposed on the surrounding image.

8. The parking assist device according to claim 4, wherein the display controlling portion displays a pair of vehicle width elongated lines indicating the width of the vehicle, together with the vehicle width extended lines so as to be superposed on the surrounding image.

9. The parking assist system according to claim 1, wherein the display controlling portion changes the distance between the vehicle width extended lines when the steering angle is return to an approximate neutral position during the parking assist operation.

10. The parking assist system according to claim 1, wherein the display controlling portion changes the distance between the vehicle width extended lines so that the vehicle width extended lines contacts with inner sides of the stall lines.
