Abstract

A driver assistance method for moving a motor vehicle, in particular for avoiding collisions, using at least one first sensor system which provides first items of obstacle information within a first detection zone for notifying the motor vehicle driver of an obstacle while an obstacle is located in the first detection zone, and using at least one second sensor system, which provides second items of obstacle information within a second detection zone which is located at an angle greater than 0° in relation to the first detection zone even if the obstacle is no longer located in the second detection zone. It is provided that the first and second items of obstacle information are combined in such a way that detection errors of the sensor systems are corrected and an updated item of obstacle information is provided. Also described is a driver assistance device, in particular for carrying out the driver assistance method according to the aforementioned embodiments.

Claims

1-11. -11. (canceled)

12. A driver assistance method for moving a motor vehicle, for avoiding a collision, the method comprising:

notifying, using at least one first sensor system, which provides a first item of obstacle information within a first detection zone, a motor vehicle driver of an obstacle while the obstacle is located in the first detection zone;

using at least one second sensor system, which provides a second item of obstacle information within a second detection zone which is located at an angle greater than 0°

in relation to the first detection zone even if the obstacle is no longer located in the second detection zone;

combining the first item of obstacle information and the second item of obstacle information so that detection errors of the sensor systems are corrected; and

providing an updated item of the obstacle information.

13. The driver assistance method of claim 12, wherein the driver is notified at least one of visually and acoustically of obstacles in the detection zones.

14. The driver assistance method of claim 12, wherein the updated obstacle information is converted to a graphical representation, which is a two-dimensional representation.

15. The driver assistance method of claim 12, wherein the driver is warned upon dropping below a minimum distance between the motor vehicle and the obstacle.

16. The driver assistance method of claim 12, wherein only obstacle information which is relevant for the driver in an instantaneous operating state of the motor vehicle is used for at least one of visually and acoustically notifying the driver.

17. The driver assistance method of claim 12, wherein at least one of the following is satisfied:

(i) sensors of the first sensor system are used by the second sensor system; and

(ii) sensors of the second sensor system are used by the first sensor system.

18. The driver assistance method of claim 12, wherein the obstacle information is stored in a memory.

19. The driver assistance method of claim 18, wherein the stored obstacle information is at least one of supplemented and corrected by the updated obstacle information, taking into account the instantaneous operating state of the motor vehicle, which includes at least one of a position, a speed and a direction of the motor vehicle.

20. A driver assistance device for providing driver assistance, comprising:

a first sensor system, which senses a first detection zone, and provides at least one first item of obstacle information;

a second sensor system, which senses a second detection zone, and provides at least one second item of obstacle information, wherein the first sensor system and the second sensor system are situated so that the first detection zone and the second detection zone are located at an angle greater than 0°

in relation to each other;

at least one evaluation arrangement having has at least one memory for storing at least one of the first item of obstacle information and the second item of obstacle information, even if the obstacle is no longer located in the detection zones, wherein the first sensor system and the second sensor system are connected to the at least one evaluation arrangement; and

at least one of a display device and a device for emitting acoustic signals, wherein the evaluation arrangement is configured as an obstacle information processing unit which corrects detection errors for combining and providing an updated item of obstacle information.

21. The driver assistance device of claim 20, wherein the at least one of the first sensor system and the second sensor system include at least one of ultrasonic sensors and radar sensors.

22. The driver assistance device of claim 20, wherein sensors for determining at least one of the position, the speed, and the direction of the motor vehicle are provided on the motor vehicle.
