Abstract

An object detection system, in particular for a motor vehicle, has multiple object detectors and/or operating modes with which different detection ranges and/or detection zones are detected. In this case, an object detector is preferably a radar sensor which has a relatively large detection range with a relatively small angular detection zone in a first operating mode and has a detection range that is small relative to the first with an enlarged angular detection zone in a second operating mode.

Claims

1-6. -6. (canceled)

7. An objection detection system comprising:

at least one of (a) a plurality of object detectors and (b) a plurality of operating modes, the at least one of (a) and (b) detecting at least one of (c) different detection ranges and (d) different detection zones.

8. The object detection system according to claim 7, wherein the object detectors include a radar sensor, the radar sensor having a first detection range with a first angular detection zone in a first operating mode and having a second detection range with a second angular detection zone in one of a second operating mode and an expanded first operating mode, the first detection range being larger than the second detection range, the first angular detection zone being smaller than the second angular detection zone.

9. The object detection system according to claim 8, further comprising an ultra short-range sensor having a small detection range and a large angular detection zone relative to the radar sensor.

10. The object detection system according to claim 9, wherein the ultra short-range sensor is one of an optical sensor, an ultrasonic sensor, and a radar sensor.

11. The object detection system according to claim 7, further comprising an additional object detector, the additional object detector being a video device for lane detection and classification of detected objects.

12. The object detection system according to claim 11, wherein the video device is one of a stereoscopic camera and a CMOS camera.

13. The object detection system according to claim 7, wherein the object detection system is for a motor vehicle.
