Abstract

A device is proposed for monitoring a front opening hood of a vehicle which is connected to a control unit for a restraint system. As a function of a signal from the device, a triggering algorithm in the control unit is influenced. The device monitors the closing state of the front opening hood, mechanical switches being preferably used.

Claims

1-9. -9. (canceled)

10. A device for monitoring a front opening hood of a vehicle, comprising:

an arrangement for connecting to a control unit for a restraint system and supplying a signal to influence a triggering algorithm in the control unit.

11. The device as recited in claim 10, further comprising:

at least one sensor for monitoring a closing state of the front opening hood.

12. The device as recited in claim 11, wherein:

the at least one sensor includes a mechanical switch.

13. The device as recited in claim 12, wherein:

the mechanical switch is open when the front opening hood is closed.

14. The device as recited in claim 11, wherein:

the at least one sensor measures in a contactless fashion.

15. The device as recited in claim 14, wherein:

the at least one sensor includes a Hall element.

16. The device as recited in claim 15, wherein:

the at least one sensor includes a force sensor.

17. The device as recited in claim 11, further comprising:

a first plurality of sensors arranged in a front region of the front opening hood; and

a second plurality of sensors arranged in a rear region of the front opening hood.

18. The device as recited in claim 12, wherein:

the mechanical switch is able to be operated by a front opening hood damper rubber.
