Abstract

There are provided a parking guidance apparatus and method. The parking guidance apparatus is configured to recognize parking spaces in which a vehicle is to be parked within a parking lot, to set any one of the recognized parking spaces to a target parking space, to calculate a one-step parking route and a multi-step parking route depending on a steering input of a driver, to display guidance markers corresponding to the one-step parking route and the multi-step parking route so as to be distinguished from each other, and to guidance parking on the basis of the guidance markers.

Claims

1. A parking guidance method comprising:

recognizing, by a controller, parking spaces included in an image captured by an image acquirer in which a vehicle is to be parked within a parking lot;

setting, by the controller, any one of the recognized parking spaces to a target parking space;

receiving, by the controller, a steering position input of a steering wheel included in the vehicle;

calculating, by the controller, a one-step parking route and a multi-step parking route corresponding to different steering position inputs, wherein the one-step parking route represents a first vehicle route of the vehicle traveling from a current position to the target parking space by performing a single steering manipulation of the steering wheel, and wherein the multi-step parking route represents a second vehicle route of the vehicle traveling from the current position to the target parking space by performing a plurality of steering manipulations of the steering wheel;

displaying, by on a display screen, a first set of guidance markers corresponding to the one-step parking route and a second set of guidance markers corresponding to the multi-step parking route, both the first set of guidance markers and the second set of guidance markers displayed concurrently on a same image to be distinguished from each other;

determining, by the controller, whether at least one of the one-step parking route or the multi-step parking route is possible based on an obstacle detected by a distance sensor; and

guiding, by the controller, parking according to at least one of the first set of guidance markers or the second set of guidance markers corresponding to the at least one of the one-step parking route or the multi-step parking route determined to be possible.

2. The parking guidance method according to claim 1, wherein setting of any one of the recognized parking spaces to the target parking space comprises setting the target parking space while the vehicle is in a stopped state.

3. The parking guidance method according to claim 1, wherein the first set of guidance markers and the second set of guidance markers are displayed up to a position at which parking guidance is possible based on a front surface of the vehicle.

4. The parking guidance method according to claim 1, wherein the first set of guidance markers and the second set of guidance markers are displayed at the same size, and a guidance marker of a limit point of a parking guidance-possible range is emphasized and displayed.

5. The parking guidance method according to claim 1, wherein guiding the parking comprises a driving trajectory of the vehicle depending on the steering input is calculated and displayed while fixing and displaying the guidance markers.

6. The parking guidance method according to claim 1, further comprising releasing the display of the first set of guidance markers and the second set of guidance markers depending on a position of the vehicle at the time of parking the vehicle depending on the parking guidance.

7. The parking guidance method according to claim 6, wherein releasing the display of the guidance markers comprises releasing the display of the guidance markers when a front surface part or a rear surface part of the vehicle coincides with at least one of the first set of guidance markers or the second set of guidance markers.

8. A parking guidance apparatus comprising:

an image acquirer configured to acquire an image around a vehicle;

a distance sensor configured to sense an obstacle around the vehicle;

a display configured to display various information; and

a controller configured to control operations of the image acquirer, the distance sensor, a steering angle sensor, and the display, wherein the controller is further configured to;

recognize parking spaces in which a vehicle is to be parked within a parking lot through the image acquirer and the distance sensor;

set any one of the recognized parking spaces to a target parking space;

detect a steering position input of a steering wheel included in the vehicle;

calculate a one-step parking route and a multi-step parking route corresponding to different steering position inputs, wherein the one-step parking route represents a first vehicle route of the vehicle traveling from a current position to the target parking space by performing a single steering manipulation of the steering wheel, and wherein the multi-step parking route represents a second vehicle route of the vehicle traveling from the current position to the target parking space by performing a plurality of steering manipulations of the steering wheel;

display a first set of guidance markers corresponding to the calculated one-step parking route and a second set of guidance markers corresponding to the calculated multi-step parking route on the display, both the first set of guidance markers and the second set of guidance markers displayed concurrently on the display so as to be distinguished from each other;

determine whether at least one of the one-step parking route or the multi-step parking route is possible based on an obstacle detected by a distance sensor; and

provide parking guidance according to at least one of the first set of guidance markers or the second set of guidance markers corresponding to the at least one of the one-step parking route or the multi-step parking route determined to be possible.

9. The parking guidance apparatus according to claim 8, wherein the controller is configured to calculate a driving trajectory depending on the steering input based on the guidance markers when the steering input based on the guidance markers is generated, and to display the calculated driving trajectory together with the guidance markers.

10. The parking guidance apparatus according to claim 8, wherein the controller is configured to:

calculate a parking route from a current position of the vehicle depending on gear shifting to the target parking space at the time of the gear shifting; and

display the guidance markers along the calculated parking route.

11. The parking guidance apparatus according to claim 8, wherein the controller is configured to release the display of the first set of guidance markers and the second set of guidance markers depending on a position of the vehicle.

12. The parking guidance apparatus according to claim 8, wherein the controller is configured to extinguish the first set of guidance markers or the second set of guidance markers when a front surface part or a rear surface part of the vehicle arrives at the corresponding first set of guidance markers or the second set of guidance markers.

13. The parking guidance apparatus according to claim 8, wherein the controller is configured to display the first set of guidance markers and the second set of guidance markers up to a position at which parking guidance is possible based on a front surface of the vehicle.

14. The parking guidance apparatus according to claim 13, wherein the controller is configured to display the first set of guidance markers and the second set of guidance markers at the same size, and to emphasize and display a guidance marker of a limit point of a parking guidance-possible range.
