Abstract

A method and a device are for detecting and reproducing a lateral and/or rear surrounding area of a vehicle with a trailer, so that the driver can monitor the surrounding area. The surrounding area is detected by at least one image capturing device which produces image data of the surrounding area. The image data is reproduced by at least one image reproducing device arranged in a field of vision of the vehicle driver. A characteristic of the reproduced image section is adapted dependent on an alignment of the trailer relative to the vehicle.

Claims

1. A method for a mirror-replacement system of a vehicle with a trailer, for reproducing an image of a lateral and/or rear surrounding area of the vehicle and the trailer, to enable a vehicle driver of the vehicle to monitor the surrounding area, wherein the method comprises:

with at least one image capturing device of the mirror-replacement system, capturing an initial image of the surrounding area and the trailer, and producing corresponding image data,

obtaining alignment data regarding an alignment of the trailer relative to the vehicle,

reproducing at least some of the image data to display at least a represented image section of the surrounding area and the trailer on at least one image reproducing device of the mirror-replacement system which is arranged in a field of vision of the vehicle driver, and

during the reproducing of the image data, adapting at least one characteristic feature of at least the represented image section of the surrounding area and the trailer dependent on the alignment data regarding the alignment of the trailer relative to the vehicle so that the trailer or at least a rear end of the trailer is displayed only in a defined edge area of the represented image section on the at least one image reproducing device.

2. The method according to claim 1, wherein the at least one characteristic feature comprises a represented image ratio of the represented image section which is adapted dependent on the alignment data.

3. The method according to claim 1, wherein the at least one characteristic feature comprises an image resolution of the represented image section which is adapted dependent on the alignment data.

4. The method according to claim 1, wherein the obtaining of the alignment data regarding the alignment of the trailer comprises determining the alignment and producing the alignment data with one or more mechanical and/or electromechanical angle measuring devices which are arranged in a trailer coupling of the vehicle.

12. The method according to claim 1, wherein the obtaining of the alignment data regarding the alignment of the trailer comprises determining the alignment and producing the alignment data.

13. The method according to claim 1, wherein the obtaining of the alignment data regarding the alignment of the trailer comprises determining the alignment and producing the alignment data by performing image processing of the image data produced by the at least one image capturing device.

14. The method according to claim 1, wherein the adapting of the at least one characteristic feature of at least the represented image section comprises selecting a portion of the initial image to be displayed as the represented image section.

15. The method according to claim 1, wherein the adapting comprises altering the at least one characteristic feature of at least the represented image section dependent on the alignment data.

17. The method according to claim 1, wherein the represented image section is reproduced on one of the at least one image reproducing device to correspond to a rear-view from a position on a side of the vehicle at which one of the at least one image capturing device is mounted.

18. The method according to claim 1, wherein the at least one characteristic feature of the represented image section is adapted so that a remainder of the represented image section other than the defined edge area displays a portion of the surrounding area that is not obscured by the trailer, and the trailer protrudes into the represented image section at most up to a defined limit that bounds the defined edge area from the remainder of the represented image section.

5. A mirror-replacement system for a vehicle with a trailer, for capturing and reproducing an image of a lateral and/or rear surrounding area of the vehicle and the trailer, to enable a vehicle driver of the vehicle to monitor the surrounding area, wherein the mirror-replacement system comprises:

at least one image capturing device which is configured and arranged to detect the surrounding area and the trailer, and to produce corresponding image data,

at least one image reproducing device which is arranged in a field of vision of the vehicle driver and is configured and arranged to receive and to reproduce at least some of the image data to display at least a represented image section of the surrounding area and the trailer on the at least one image reproducing device,

an input configured and arranged to receive alignment data regarding an alignment of the trailer relative to the vehicle, and

one or more image processing devices which are configured and arranged to adapt at least one characteristic feature of at least the represented image section dependent on the alignment data regarding the alignment of the trailer relative to the vehicle so that the trailer or at least a rear end of the trailer is displayed only in a defined edge area of the represented image section on the at least one image reproducing device.

6. The mirror-replacement system according to claim 5, wherein the one or more image processing devices are configured so that the at least one characteristic feature comprises a represented image ratio of the represented image section which is adapted by the one or more image processing devices dependent on the alignment data.

7. The mirror-replacement system according to claim 5, wherein the one or more image processing devices are configured so that the at least one characteristic feature comprises an image resolution of the represented image section which is adapted by the one or more image processing devices dependent on the alignment data.

8. The mirror-replacement system according to claim 5, further comprising one or more mechanical and/or electromechanical angle measuring devices which are arranged in a trailer coupling of the vehicle, and which are configured and arranged to produce the alignment data and to transmit the alignment data to the input.

9. The device mirror-replacement system according to claim 5, further comprising electronic image processing devices which are configured and arranged to produce the alignment data by image processing of the image data, and which are configured and arranged to transmit the alignment data to the input.

10. A vehicle comprising a mirror-replacement system according to claim 5 arranged in and/or on a vehicle body.

11. The mirror-replacement system according to claim 5, further comprising an angle determination device configured and arranged to produce the alignment data regarding the alignment of the trailer and to transmit the alignment data to the input.

16. The vehicle according to claim 10, wherein the vehicle includes no side-mounted exterior mirrors.

19. A method for a mirror-replacement system of a vehicle with a trailer, for reproducing an image of a lateral and/or rear surrounding area of the vehicle and the trailer, to enable a vehicle driver of the vehicle to monitor the surrounding area, wherein the method comprises:

with at least one image capturing device of the mirror-replacement system, capturing an initial image of the surrounding area and the trailer, and producing corresponding image data,

obtaining alignment data regarding an alignment of the trailer relative to the vehicle,

reproducing some of the image data to display a represented image section of the surrounding area and the trailer on at least one image reproducing device of the mirror-replacement system which is arranged in a field of vision of the vehicle driver, and

dependent on the alignment data, selecting a particular portion of the initial image to be displayed as the represented image section during the reproducing of the image data and/or altering an image zoom ratio of the represented image section during the reproducing of the image data, so that the trailer is always displayed only in a predefined edge area of the represented image section and a remainder of the represented image section other than the predefined edge area always displays a portion of the surrounding area that is not obscured by the trailer.
