Abstract
A device for impact detection in a motor vehicle has both a precrash sensor and an impact sensor, and when an impact is detected, the noise threshold for the impact sensor is lowered, so that the deployment time can then be determined as a function of the signals of the precrash sensor and the impact sensor. Various features are extracted from the signals of the impact sensor and then compared with continuous threshold functions to detect a deployment case. The deceleration and/or velocity and/or predisplacement may be used as features.
