Abstract

A control/evaluation system for a set of sensors, in particular in motor vehicles, has a plurality of areas, each of which has at least one controller and a plurality of sensor devices connected thereto; the controllers may be connected to each other for a common application function.

Claims

1. A control and evaluation system for a set of sensor devices, comprising:

at least one controller and sensor devices connected to the at least one controller in each of a plurality of areas, the at least one controller of each of the plurality of areas being connected to one another, the at least one controller being for controlling and evaluating sensor signals of the sensor devices; and

at least another controller device connected to the at least one controller for performing at least one of a pre-crash function, a parking assistance function and an airbag function.

2. The system of claim 1, wherein the set of sensors is in a motor vehicle.

3. The system of claim 1, further comprising:

a bus system for connecting the at least one controller in each of the plurality of areas to each other.

4. The system according to claim 3, wherein the bus system includes a controller area network bus system.

5. The system of claim 1, further comprising:

one of a bus system and a point-to-point connector arrangement to couple the sensor devices of one of the plurality of areas to a corresponding one of the at least one controller of the one of the plurality of areas.

6. The system of claim 1, wherein the at least one controller of each of the plurality of areas has an identical configuration.

7. The system of claim 1, wherein at least one sensor device is integrated with a corresponding one of the at least one controller to form a sensor and controller device.

8. The system of claim 7, further comprising:

a bus system for coupling the sensor and controller device to the other sensor and controller devices for the common application function.

9. The system of claim 7, further comprising:

one of a bus system and a point-to-point connector arrangement to couple the sensor devices of an area of the plurality of areas to a corresponding sensor and controller device.

10. The system of claim 7, wherein the sensor and controller device in a particular area of the plurality of areas is modified minimally from other ones of the sensor devices.

11. The system of claim 1, wherein the sensor devices have an identical configuration.

12. The system of claim 1, wherein the sensor devices are configured as close-range sensors.

13. The system of claim 1, wherein the plurality of areas include at least one of a front area, a rear area, a side area, and a corner area.

14. The system of claim 13, wherein the side area is subdividable into a left-side area and a right-side area.

15. The system of claim 1, wherein up to six sensor devices are associated with an area of the plurality of areas.

16. The system of claim 1, wherein the at least one controller of each of the plurality of areas includes uniform software.

17. The system according to claim 16, wherein the uniform software includes parameterization for assigning a corresponding one of the at least one controller.

18. The system according to claim 1, wherein the parking function is performed.

19. The system according to claim 1, wherein the pre-crash function is performed.

20. The system according to claim 1, wherein the airbag function is performed.
