Abstract

A method provides driver information in a motor vehicle, in which method a recording device of the motor vehicle captures an image flow containing images of at least one part of the environment of the motor vehicle. A display unit in the interior of the motor vehicle reproduces at least one image section of the image flow. A display control unit of the motor vehicle automatically modifies the environmental section shown to the driver by reproducing the image section using the display unit. During the reproduction of the image section, in addition to the representation of the environmental section, at least first optical information relating to the position of the environmental section relative to the motor vehicle is output to the driver.

Claims

1. A method for providing information to a driver in a motor vehicle, the method comprising the acts of:

capturing an image flow containing images of at least one part of an environment of the motor vehicle using a recording device of the motor vehicle;

reproducing a selected image section of the image flow on a display unit in an interior of the motor vehicle, wherein the selected image section is a reduced section of the image flow corresponding to an environmental section of the environment of the motor vehicle;

arranging the selected image section within a display surface of the display unit in a position corresponding to that of the environmental section relative to the motor vehicle, wherein the display surface is larger than a display area of the selected image section;

automatically modifying via a display control unit of the motor vehicle the environmental section to be displayed for the driver by shifting the selected image section within the image flow, and wherein the position in which the selected image section is arranged within the display surface is shifted such that the position of the selected image section continues to correspond to the environmental section displayed for the driver following said automatically modifying; and

during the reproducing of the selected image section, in addition to a representation of the environmental section, displaying for the driver at least first optical information that indicates a position of the currently-represented environmental section relative to the motor vehicle, wherein the first optical information comprises a symbolic representation that is distinct from and in addition to the representation of the environmental section.

2. The method according to claim 1, wherein the display unit is integrated into a reflecting surface of a rear-view mirror of the motor vehicle or is formed as the reflecting surface of the rear-view mirror, and further comprising the act of transferring a display surface not used for representing the environmental section into a reflective state.

3. The method according to claim 1, wherein the image section is reproduced in a distorted manner corresponding to the position of the environmental section relative to the motor vehicle.

4. The method according to claim 1, wherein the image section is arranged, corresponding to the position of the environmental section relative to the motor vehicle, in a defined plane of a three-dimensional representation.

5. The method according to claim 1, wherein the image section is arranged, corresponding to a zoom factor or aperture angle used for determining the environmental section or resulting from the determination of the environmental section, in a defined plane of a three-dimensional representation.

6. The method according to claim 1, wherein the reproduction of the image section is accompanied by a symbolic representation of the position of the environmental section relative to the motor vehicle.

7. The method according to claim 1, wherein the reproduction of the image section is accompanied by one of a symbolic representation of a zoom factor and an aperture angle used for determining the environmental section or resulting from the determination of the environmental section.

8. The method according to claim 1, wherein the image section is compressed, at least intermittently, in at least one border area in relation to a central image area.

9. The method according to claim 1, wherein the display control unit determines at least one previous position of the motor vehicle and the display control unit adapts the environmental section as a function of the previous position of the motor vehicle.

10. The method according to claim 1, wherein automatically modifying the environmental section comprises adapting the captured image flow of the environment by at least one of panning the recording device and switching to another recording device.

11. The method according to claim 1, wherein automatically modifying the environmental section comprises performing a virtual camera pan or a virtual camera with respect to the environmental section displayed for the driver using the display unit.

12. The method according to claim 1, wherein the first optical information indicates a direction in which the currently-represented environmental section lies relative to the motor vehicle.

13. The method according to claim 1, where the symbolic representation is distinct from images captured by the recording device of the motor vehicle.
