Parking guidance method for vehicle using around view monitor
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.
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, in response to the selected parking type, a parking reference region or a parking reference line respectively corresponding to a parking target space in which the vehicle is to be parked, wherein the parking reference region is aligned with the center part of a parking target space and the parking reference line is aligned with a side of a parking section line of the parking target space;
displaying a parking alignment reference line when the vehicle travels at a relatively low speed and a steering angle thereof is changed by at least a threshold value; and
guiding the vehicle to a parked position 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 displayed 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 reference 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 aligned with the parking section line at a front side 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 when a steering wheel of the vehicle is in a stationary position, a vehicle speed exceeds a threshold value, a shift lever of the vehicle is positioned at a p-gear position, or a parking completion button is actuated, a parking guidance is completed.
10. A parking guidance method for a vehicle, using an around view monitor (AVM), comprising:
displaying, in response to selection of a parking type, a parking reference region or a parking reference line, respectively corresponding to a parking space in which the vehicle is to be parked, to be superimposed on a top view image, wherein the parking reference region is aligned with the center part of a parking target space and the parking reference line is aligned with a side of a parking section line of the parking target space;
guiding the vehicle to an initial position based on the parking reference region or the parking reference line;
guiding a driver of the vehicle to turn a steering wheel thereof to a predetermined angle in a first direction when the vehicle is disposed at the initial position;
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 reverse turning;
guiding the vehicle to a reverse position by aligning the parking alignment reference line with a parking section line based on the parking reference region or the parking reference line; and
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 displaying the parking reference region or the parking reference line, 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), guiding the vehicle to the reference position 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), guiding the vehicle to the reverse position 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 guiding the driver of the vehicle to turn the steering wheel is performed to guide the driver to fully turn the steering wheel of the vehicle in the first direction, and displaying the parking alignment reference line is performed to set and display the parking alignment reference line based on the steering wheel being fully turned in the second direction.
15. The method of claim 10 , wherein displaying a parking alignment reference line 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 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 guiding the driver to turn the steering wheel of the vehicle to the predetermined angle is performed.
