Abstract

A device for recognizing a pole crash, situated in a vehicle. The pole crash is determined on the basis of an impact velocity, which is recognized by an environment sensor, and an acceleration, which occurs in upon impact and is recognized by an impact sensor. In particular, the time between the impact and the impact object hitting the engine block is determined to identify a pole crash.

Claims

1-4. -4. (canceled)

5. A device for recognizing a pole crash, comprising:

at least one environment sensor to determine an impact velocity;

at least one impact sensor to determine an acceleration occurring in a crash; and

a processor configured to detect the pole crash on the basis of the impact velocity and the acceleration and to activate a restraining device as a function thereof.

6. The device as recited in claim 5, wherein the processor is configured to determine a time between a moment of impact and a moment an impact object strikes an engine block, using the impact velocity and the acceleration, the processor determining the pole crash as a function of the time.

7. The device as recited in claim 5, wherein the at least one environment sensor is a radar sensor.

8. The device as recited in claim 5, wherein the at least one environment sensor is an ultrasonic sensor.
