Abstract

The invention provides a method for assisting in a parking operation for a motor vehicle (1) using a driver assistance system (2). The driver assistance system (2) determines a parking path along which the motor vehicle (1) can be parked into a parking space (21) or driven out of the parking space (21). Image data about surroundings (10 to 13) of the motor vehicle (1) are captured by at least one optical capture device (5a to 5d) of the driver assistance system (2). The image data are processed to produce an image (19) which shows a perspective view of at least one surrounding area (20) next to the motor vehicle (1). The image (19) is displayed on a display device (3). The image (19) is produced by taking account of a current position of the motor vehicle (1) on the calculated parking path. By way of example, a direction of view (14) and/or a field of view (15) from which the perspective view is shown can be set on the basis of the current position of the motor vehicle (1) on the parking path. The invention also provides a driver assistance system (2) and a motor vehicle (1).

Claims

1. A method for assisting in a parking operation for a motor vehicle using a driver assistance system by, comprising:

determining a parking path along which the motor vehicle is parked into a parking space or driven out of the parking space;

capturing image data about surroundings of the motor vehicle using at least one optical capture device of the driver assistance system;

processing the image data to produce an image which shows a perspective view of at least one surrounding area next to the motor vehicle; and

displaying the image on a display device, wherein

the image is produced by taking account of a current position of the motor vehicle on the parking path.

2. The method according to claim 1, wherein a direction of view and/or a field of view from which the perspective view is shown is/are set on the basis of the current position of the motor vehicle on the parking path.

3. The method according to claim 1, wherein a size of the mapped surrounding area is set on the basis of the current position of the motor vehicle on the parking path.

4. The method according to claim 1, wherein the image data are processed such that the image shows a plan view of at least the surrounding area next to the motor vehicle from above the motor vehicle.

5. The method according to claim 1, wherein for at least one section of the parking path the image also shows at least one area of the motor vehicle in addition to the surrounding area.

6. The method according to claim 5, wherein the map of the motor vehicle is presented at a fixed location in the displayed image, while the map of the surrounding area is produced from the image data afresh each time.

7. The method according to claim 1, wherein during an operation of capturing the parking space, while the motor vehicle is passing the parking space, the perspective view is shown from such a direction of view as has a direction component for a direction of travel of the motor vehicle and a direction component for an, in particular right-hand, transverse half-axis of the motor vehicle.

8. The method according to claim 1, wherein when the motor vehicle is in an initial area of the carriageway, the perspective view is shown from a direction of view that points in the direction of an end of the parking path.

9. The method according to claim 1, wherein when a remaining distance for the parking path is below a prescribed minimum, the perspective view is shown from a direction of view that coincides with a vehicle vertical axis.

10. The method according to claim 1, wherein while the motor vehicle is being moved along the parking path, a direction of view and/or a field of view from which the perspective view is shown is/are altered progressively for at least a section of the parking path, on the basis of the current speed of the motor vehicle and/or on the basis of a remaining distance for the parking path.

11. The method according to claim 1, wherein the image data are captured by at least three optical capture devices.

12. The method according to claim 1, wherein the at least one optical capture device has a capture angle from a range of values from 170°

to 195°

.

13. The driver assistance system for a motor vehicle, for assisting in a parking operation, comprising:

at least one optical capture device for capturing image data about surroundings of the motor vehicle;

a control device for determining a parking path for the parking operation and for processing the image data to produce an image which shows a perspective view of at least one surrounding area next to the motor vehicle; and

a display device for displaying the image,

wherein the control device produces the image by taking account of a current position of the motor vehicle on the parking path.

14. A motor vehicle having a driver assistance system according to claim 13.
