Method for controlling release of passenger airbag in vehicle

摘要

The method involves monitoring a signal indicative of the acceleration of the vehicle and generating several signal samples. The path driven by the vehicle is determined on the basis of the signal samples. The method further involves determining a first, second and third average acceleration of the passenger area on the basis of the first, second and third numbers of the signal samples. An impact is determined on the basis of the first average acceleration. A fourth average acceleration is determined on the basis of the second number of signal samples and the impact. The fourth average acceleration is compared with several threshold values each based on the distance travelled. A signal is then formed on the basis of the impact of the second average acceleration to release an inflatable retaining device, e.g. an airbag, when this exceeds at least one of the threshold values.
