Abstract

The present invention provides a parking control system including: a parking mode selection unit that supports a first-stage selection and a second-stage selection, wherein a parallel parking mode or a perpendicular parking mode is selected in the first-stage selection, and a head-in parking mode or a reverse parking mode is selected in the second-stage selection in cases where the perpendicular parking mode is selected in the first-stage selection; a sensor unit comprising a plurality of sensors mounted on one or more of the front, rear, and sides of a vehicle; a parking space search unit that searches for a parking space based on a value detected by the sensor unit; a path setting unit that sets a parking path along which the vehicle is parked in the parking space, which is discovered by the parking space search unit, according to the parking mode selected by the parking mode selection unit; and a parking controller that controls the vehicle to move along the parking path set by the path setting unit.

Claims

1. A parking control system comprising:

a parking mode selection unit that supports a first-stage selection and a second-stage selection, wherein one of a right perpendicular parking mode, a left perpendicular parking mode, a right parallel parking mode, and a left parallel parking mode is selectable in the first-stage selection, and a head-in parking mode or a reverse parking mode is selectable in the second-stage selection in cases where the right perpendicular parking mode or the left perpendicular parking mode is selected in the first-stage selection;

a sensor unit comprising a plurality of sensors mounted on one or more of the front, rear, and sides of a vehicle;

a parking space search unit that searches for a parking space based on a value detected by the sensor unit;

a path setting unit that sets a parking path along which the vehicle is parked in the parking space, which is discovered by the parking space search unit, according to the parking mode selected by the parking mode selection unit; and

a parking controller that controls the vehicle to move along the parking path set by the path setting unit,

wherein the parking space search unit searches for the parking space when the speed of the vehicle is reduced to a predetermined speed or lower.

2. The parking control system of claim 1, wherein the parking controller operates the parking space search unit to search for the parking space and then controls the parking mode selection unit to perform the second-stage selection in cases where either the right perpendicular parking mode or the left perpendicular parking mode is selected in the first-stage selection.

3. The parking control system of claim 1, wherein the parking controller operates the parking space search unit to search for the parking space and then operates the path setting unit to set the parking path in cases where either the right parallel parking mode or the left parallel parking mode is selected in the first-stage selection.

4. The parking control system of claim 1, wherein the parking space search unit determines a parking mode in which the vehicle is able to be parked in the discovered parking space.

5. The parking control system of claim 4, further comprising:

a display device on which parking modes of each stage are sequentially displayed according to a user'"'"'s control input.

6. The parking control system of claim 5, wherein the parking mode selection unit displays the parking mode determined by the parking space search unit on the display device, as a first-stage selection screen.

7. The parking control system of claim 5, wherein the parking mode determined by the parking space search unit is displayed on the display device.

8. The parking control system of claim 5, wherein a screen representing that a parking control is possible is displayed on the display device when the vehicle is at a controllable position after the parking space is discovered by the parking space search unit and the parking mode is selected by the parking mode selection unit.

9. The parking control system of claim 1, further comprising:

a display device on which parking modes of each stage are simultaneously displayed on a single screen,

wherein the parking mode selection unit supports the first-stage selection and the second-stage selection such that a parking mode is selected according to a user'"'"'s control input on the display device.

10. The parking control system of claim 1, wherein the parking space search unit selects one or more selectable parking modes, in which the vehicle is able to be parked in the parking space discovered by the parking space search unit, among the right perpendicular parking mode, the left perpendicular parking mode, the right parallel parking mode, and the left parallel parking mode.

11. The parking control system of claim 10, further comprising a display device displaying the first-stage selection or the second-stage selection,

wherein an order of displaying the first-stage selection is the one or more selectable parking modes selected by the parking space search unit first, and one or more parking modes unselected by the parking space search unit later.

12. A parking control method comprising:

providing a first-state selection in which one of a right perpendicular parking mode, a left perpendicular parking mode, a right parallel parking mode, and a left parallel parking mode is selectable;

when the right perpendicular parking mode or the left perpendicular parking mode providing is selected in the first-stage selection, providing a second-stage selection in which a head-in parking mode or a reverse parking mode is selectable;

searching a parking space;

creating a parking path for the discovered parking space according to the head-in parking mode or the reverse parking mode which is selected in the second-stage parking mode selection step; and

controlling the parking of a vehicle according to the created parking path,

wherein the searching the parking space comprises searching for the parking space when the speed of the vehicle is reduced to a predetermined speed or lower.

13. The parking control method of claim 12, wherein the searching the parking space comprises determining a parking mode in which the vehicle is able to be parked in the discovered parking space, and the providing the first-stage selection comprises displaying the parking mode determined in the searching the parking space as a first-stage selection screen.

14. The parking control method of claim 12, wherein the searching the parking space comprises selecting one or more selectable parking modes, in which the vehicle is able to be parked in the parking space discovered by a parking space search unit, among the right perpendicular parking mode, the left perpendicular parking mode, the right parallel parking mode, and the left parallel parking mode.

15. The parking control method of claim 14, further comprising displaying the first-stage selection or the second-stage selection.

16. The parking control method of claim 12, further comprising determining, by a parking space search unit, a parking mode in which the vehicle is able to be parked in the searched parking space.

17. The parking control method of claim 12, further comprising simultaneously displaying parking modes of each stage on a single screen.
