A relatively uncomplicated process for generating collision signals that describe various collision processes involving motor vehicles. The process involves deriving a core signal by low-pass filtering from a collision signal actually measured, splitting this core signal into several signal segments, simulating each signal segment by a transmission function, then combining all the transmission functions into one overall transmission function, and forming one or more new collision signals by varying at least one parameter of the overall transmission function.

A method and a device for deploying a restraint system, which avoids false deployments at the least possible expense by using an acceleration sensor arrangement that includes two sensitivity axes oriented in different directions. An acceleration measured with respect to one of the two sensitivity axes is used for a plausibility check of a deployment decision, which is determined from an acceleration measured with respect to the other sensitivity axis. A trigger signal is only generated if a deployment decision signal and a plausibility signal are present at the inputs of an AND logic circuit at the same time.

So that an arrangement may decide to trigger a safety device in as error-free and reliable a manner as possible, provision is made for a first arrangement, which derives a first decision criterion for triggering a safety device from the measured turning rate at least about the longitudinal axis of the vehicle and/or from the measured accelerations at least in the direction of the transverse axis and the vertical axis of the vehicle. In addition, a second arrangement is present, which, independent of the first arrangement, derives a second decision criterion. A circuit arrangement then generates a triggering signal for the safety device, when both decision criteria are satisfied at the same time.

A method and/or a device for forming a robust and reliable deployment criterion for a restraint system in a motor vehicle is formed with the help of a fuzzy classifier which receives at least two input quantities. The first input quantity is an operating time which begins when the measured acceleration exceeds a predetermined threshold; and a second input quantity takes into account the change in vehicle speed determined from the measured acceleration.

System for producing a release signal for a vehicle safety device

An apparatus for tripping a system for the protection of occupants of a vehicle has a first sensor (10) for sensing the acceleration of the vehicle in its direction of forward motion and a second sensor (12) for sensing the acceleration of the vehicle in a direction transverse to its direction of forward motion. The two sensors are under the control of control means (14,16) which triggers the occupant protection system in dependence upon the signals from the first and second sensors (10,12).

An electronic device, in particular a system for safeguarding vehicle occupants, comprises at least two acceleration-sensitive sensors arrangements. To test the readiness for operation of the sensor arrangements, output signals from the sensor arrangements are compared. Output signals, which occur as the result of accelerations arising during normal operation of the vehicle, are also drawn upon when the comparison is made.

In a method for controlling the release of a passenger restraint system in a vehicle, an acceleration signal is measured and integrated with respect to time to obtain a velocity signal. A release threshold value for the velocity signal is determined. If the velocity signal then falls below the release threshold value, thus indicating a vehicle collision, the passenger restraint system is released. The release threshold value is controlled depending on the type of accident situation and upon the operating parameters of the vehicle to increase the release sensitivity of the passenger restraint system. For example, the release threshold value is adjusted based on the value of the velocity signal. If the velocity signal decreases in value, then the release threshold is lowered to a more sensitive value.
