Abstract

A safety device for motor vehicles includes an impact detection system and a triggering device for triggering a braking operation as a function of a signal of the impact detection system characterized in that the triggering device is designed for the purpose of triggering the braking operation when the impact detection system indicates the beginning of an impact.

Claims

1-5. -5. (canceled)

6. A safety device for a motor vehicle, comprising:

an impact detection system; and

a triggering device adapted to trigger a braking operation as a function of a signal of the impact detection system;

wherein the triggering device is configured to trigger the braking operation when the impact detection system indicates a beginning of an impact.

7. The safety device according to claim 6, wherein the impact detection system is part of an airbag system and is also configured to activate an airbag.

8. The safety device according to claim 6, further comprising a position-finding system adapted to locate obstacles in front of the vehicle and a collision prediction device configured to predict an imminent collision with an obstacle, triggering of the braking operation by the triggering device being dependent on a result of the collision prediction.

9. The safety device according to claim 8, wherein the impact detection system includes at least one acceleration sensor configured to measure an acceleration of the vehicle caused by an impact, and the triggering device is configured to trigger the braking operation when the acceleration exceeds a threshold value and to vary the threshold value as a function of the result of the collision prediction.

10. The safety device according to claim 9, wherein the impact detection system is part of an airbag system and is also configured to activate an airbag, the triggering device configured to vary the threshold value for triggering the airbag system as a function of the result of the collision prediction.
