Abstract

A device for approving automatic guidance of a vehicle, having an interface to a monitoring apparatus for at least partially monitoring a vehicle driver located in the vehicle, having an interface to an apparatus for automatically guiding the vehicle and for ascertaining a travel direction of the vehicle when automatic guidance is to be performed, and having an analysis unit for comparing a field of vision of the driver, which is determined from the monitoring of the driver, to the travel direction of the vehicle during the automatic guidance, automatic guidance only being approved if the travel direction of the vehicle during the automatic guidance is in the field of vision of the driver.

Claims

1. A device for approving automatic guidance of a vehicle, comprising:

a camera system mounted in a rear space of the vehicle behind a vehicle driver, directed toward the driver, and monitoring a field of vision of the driver when backing into a parking space;

an interface to an apparatus for automatically guiding the vehicle and for ascertaining a reverse travel direction of the vehicle for backing into the parking space when automatic guidance is to be performed; and

an analysis unit for comparing a field of vision of the driver, which is determined from the monitoring of the driver, to the travel direction of the vehicle during the automatic guidance, wherein automatic guidance is only approved if the reverse travel direction of the vehicle during the automatic guidance is in the field of vision of the driver.

2. The device as recited in claim 1, wherein the vehicle is automatically guided in reverse into a parking space.

3. The device as recited in claim 1, wherein the camera system ascertains a head position of the vehicle driver to determine the field of vision of the driver from the ascertained head position of the driver.

4. The device as recited in claim 2, wherein the camera system ascertains a viewing direction of the vehicle driver to determine the field of vision of the driver from the ascertained viewing direction.

5. The device as recited in claim 3, wherein the camera system is situated on a vehicle roof.

6. A method for approving automatic guidance of a vehicle, comprising:

monitoring a field of vision of a driver located in the vehicle when backing into a parking space using a camera mounted in a rear space of the vehicle behind the driver and directed toward the driver;

ascertaining a reverse travel direction of the vehicle for backing into the parking space when automatic guidance is to be performed; and

comparing the ascertained travel direction to the ascertained field of vision of the driver, wherein automatic guidance is only approved if the reverse travel direction of the vehicle during the automatic guidance is in the ascertained field of vision of the driver.

7. The method as recited in claim 6, wherein at least one of a head position and a viewing direction of the driver is ascertained, and the field of vision of the driver is determined from at least one of the ascertained head position and the viewing direction.

8. The method as recited in claim 6, wherein approval of automatic guidance is canceled when it is determined that the travel direction of the vehicle during the automatic guidance is no longer in the field of vision of the driver.

9. The method as recited in claim 7, wherein approval of automatic guidance is canceled when it is determined that the travel direction of the vehicle during the automatic guidance is no longer in the field of vision of the driver.

10. The method as recited in claim 8, wherein the vehicle is automatically decelerated in the event of cancellation of approval of the automatic guidance.

11. The method as recited in claim 9, wherein the vehicle is automatically decelerated in the event of cancellation of approval of the automatic guidance.

12. The method as recited in claim 10, wherein a warning for notification of an imminent or beginning automatic deceleration is output with or before initiation of an automatic deceleration.

13. The method as recited in claim 11, wherein a warning for notification of an imminent or beginning automatic deceleration is output with or before initiation of an automatic deceleration.

14. The method as recited in claim 6, further comprising:

detecting a position of a head of the driver on a head support using a sensor system integrated into the head support; and

monitoring the field of vision of the driver based in part on the detected head position of the driver.

15. The method as recited in claim 6, further comprising:

detecting a head orientation of the driver using a camera mounted in a dashboard of the vehicle front of the driver sensor system integrated into the head support; and

monitoring the field of vision of the driver based in part on the detected head orientation of the driver and the field of vision of the driver when backing into a parking space using the camera mounted in the rear space of the vehicle behind the driver and directed toward the driver.
