Abstract: A method and a device for triggering a restraining device in a vehicle are provided. At least one parameter that is representative of the probability of a collision of the vehicle with an obstacle is determined and the restraining device is triggered when such a collision probability is recognized. The intensity of the triggering of the restraining device is a function of the value of the at least one parameter.

Abstract: A device for controlling restraining means takes a signal characterizing the trailer into consideration in controlling the restraining means.

Abstract: A method for determining the trigger time for restraint means in a vehicle is provided, where, by forming two time windows for the speed reduction in a crash, the slope of the speed reduction in the respective time windows and the position of the time windows are determined. In this manner, an exact determination of the trigger time in conjunction with a crash time and the crash speed may be achieved, which are ascertained with the aid of a pre-crash sensory system.

Abstract: An apparatus for triggering a restraint apparatus, arrangement(s) or structure(s) in which, with a precrash sensor system, the apparatus generates a signal as a function of which the restraint apparatus, arrangement(s) or structure(s) is/are triggered. The precrash sensor system includes a combination of an ultrasound sensor system and a microwave sensor system. The ultrasound sensor system serves to detect objects at a speed of up to 40 km/h, while the microwave sensor system is used to detect objects up to a relative speed of 200 km/h.

Abstract: A method for activating a restraint system in a vehicle, in which the restraint system is activated as a function of a speed, an activation characteristic, and at least one quantity derived from an acceleration signal, and in which the at least one quantity exceeds a threshold function that is set as a function of the impact speed and a required activation time. The activation characteristic of a particular accident type runs linearly to a first impact speed value. The activation characteristic runs with a second slope between the first impact speed and a second impact speed value, the first and the second impact speed value depending on the particular vehicle type.

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.
