Arrangement for recognising the type of occupation of a vehicle seat
First Claim
Patent Images
1. An arrangement for detecting a type of occupancy of a vehicle seat, comprising:
- at least one sensor responding to movements of one of a passenger and an object occupying the vehicle seat, the at least one sensor generating a sensor output signal;
means for decomposing the sensor output signal into a plurality of signal components, each of the plurality of signal components having a selected frequency range, the frequency range being selected as a function of at least one vehicle operation parameter having an influence on the sensor output signal;
means for comparing the plurality of signal components, the means for comparing generating a comparison signal; and
means for determining whether the vehicle seat is occupied by a passenger as a function of the comparison signal.

Abstract
An arrangement, having at least one motion sensor in the vehicle seat, detects with a high reliability whether or not the vehicle seat is occupied by a person. For this purpose, the sensor output signal is analyzed into multiple signal components by frequency selection, and decision-making criterion for occupancy or non-occupancy of the vehicle seat by a passenger is formed by comparing the frequency-selective signal components.
