METHOD FOR ESTABLISHING A RELEASE CRITERION FOR RESTRAINING MEANS

摘要

The aim of the invention is to establish a clear difference between release and non-release cases. The measured acceleration (a) of a vehicle is submitted to a low-pass filtration (FI). A release threshold ( DELTA vs) is produced according to the filtered acceleration signal (af). As soon as an acceleration signal (a) is measured, said signal (a) is examined during a first time segment in order to detect characteristic features which indicate a crash event that should not result in a release of the restraining means. The limit frequency of the low-pass filter (FI) is reduced during a given time segment when such a non-release case is detected.
