Abstract

There is provided a parking guidance method for a vehicle, of displaying a guidance line for guidance of perpendicular, parallel parking in an AVM synthetic image to provide parking guidance. The method includes entering a parking support mode, displaying parking type information in the parking support mode to select a parking type, displaying a parking reference region or a parking reference line with regard to a parking target space in which the vehicle is to be parked depending on the parking type, displaying a parking alignment reference line when the vehicle travels at a relatively low speed and a steering angle thereof is changed by a threshold value or more, and guiding the vehicle to be aligned such that the parking alignment reference line coincides with a parking section line based on the parking reference region or the parking reference line.

Claims

1. A parking guidance method for a vehicle, using an around view monitor (AVM) comprising:

entering a parking support mode;

displaying parking type information in the parking support mode to select a parking type;

displaying a parking reference region or a parking reference line with regard to a parking target space in which the vehicle is to be parked depending on the parking type;

displaying a parking alignment reference line when the vehicle travels at a relatively low speed and a steering angle thereof is changed by a threshold value or more; and

guiding the vehicle to be aligned such that the parking alignment reference line coincides with a parking section line based on the parking reference region or the parking reference line.

2. The method of claim 1, wherein when the parking type is perpendicular parking, the parking reference region is displayed, and the parking reference region and the parking alignment reference line are represented in a single direction based on the vehicle.

3. The method of claim 2, wherein a message guiding that the parking reference region is to be positioned on the central part of the parking target space is displayed.

4. The method of claim 2, wherein a message guiding the vehicle to travel forward until the parking alignment reference line coincides with the parking section line of the parking target space and then stop is displayed.

5. The method of claim 1, wherein when the parking type is parallel parking, the parking reference line is displayed, and the parking reference line is displayed in a ‘

T’

form to be mapped with the parking section line of the parking target space.

6. The method of claim 5, wherein the parking reference line and the parking alignment line are displayed in directions opposite to each other based on the vehicle.

7. The method of claim 5, wherein a message guiding that the parking reference line is to be positioned at a front side of the parking section line of the parking target space is displayed.

8. The method of claim 5, wherein a message guiding the vehicle to reverse until the parking alignment reference line coincides with the parking section line of the parking target space and then stop is displayed.

9. The method of claim 1, wherein in the case of one of cases in which a steering wheel of the vehicle is in neutral, a vehicle speed exceeds a threshold value, the shift lever of the vehicle is positioned at a p-gear position, and a parking completion button has a button input applied thereto, a parking guidance is completed.

10. A parking guidance method for a vehicle, using an around view monitor (AVM), comprising:

(a) displaying at least one or more of a parking reference region and a parking reference line to be superimposed on a top view image;

(b) guiding the vehicle to be disposed at an initial position through the parking reference region or the parking reference line;

(c) guiding a driver to turn a steering wheel of the vehicle to a predetermined angle in a first direction when the vehicle is disposed at the initial position;

(d) displaying a parking alignment reference line to be superimposed on the top view image, the parking alignment reference line being set based on an expected inner trajectory of turning of the vehicle when the steering wheel is turned to a predetermined angle in a second direction opposite to the first direction and the vehicle is back turning;

(e) guiding the vehicle to be disposed at a reverse position by aligning the parking alignment line with a parking section line; and

(f) guiding the driver to turn the steering wheel of the vehicle to a predetermined angle in the second direction when the vehicle is disposed at the reverse position.

11. The method of claim 10, further comprising a step of selecting a parking type prior to (a) step, wherein the parking type includes at least one of perpendicular parking (left), perpendicular parking (right), parallel parking (left) and parallel parking (right).

12. The method of claim 11, wherein when the parking type is selected as the perpendicular parking (left) or the perpendicular parking (right), (e) step is performed to guide the vehicle to travel forward in a state in which the steering wheel is turned to the predetermined angle in the first direction such that the parking alignment reference line is aligned with the parking section line.

13. The method of claim 11, wherein when the parking type is selected as the parallel parking (left) or the parallel parking (right), (e) step is performed to guide the vehicle to travel backward in the state in which the steering wheel is turned to the predetermined angle in the first direction such that the parking alignment reference line is aligned with the parking section line.

14. The method of claim 10, wherein the (c) step is performed to guide the driver to fully turn the steering wheel of the vehicle in the first direction, and (d) step is performed to set and display the parking alignment reference line based on time that the steering wheel is fully turned in the second direction.

15. The method of claim 10, wherein (d) step is performed to calculate a tangent line of an inner trajectory of turning of vehicle at a point spaced apart from the vehicle in a rear direction thereof by a predetermined distance, and the parking alignment reference line is set and displayed as a line parallel to the tangent line.

16. The method of claim 10, further comprising guiding the vehicle to travel backward in a state in which the steering wheel is turned to the predetermined angle in the second direction so as to be parked in a parking target space, after (f) step is performed.
