Abstract:
1. A method for recognizing a seat occupancy of a seat, which comprises: detecting at least one measuring signal by way of a seat occupancy sensor system; allocating the measuring signal by an allocation rule to a weight signal that is representative of a weight with which the seat is occupied; adapting the allocation rule when the weight signal over time is greater than a predetermined upper threshold value and if subsequently the weight signal during a predetermined first duration lies in a first weight range about a zero weight value, then the allocation rule is adapted such that a then-current measuring signal is allocated to a weight signal reduced in amount by a predetermined percentage proportion of the weight signal; adapting the allocation rule if the weight signal over the course of time is initially smaller than the predetermined upper threshold value and if subsequently the weight signal lies in a predetermined second weight range about the zero weight value during a predetermined second duration, which is greater than the first duration, wherein the allocation rule is adapted such that a then-current measuring signal is allocated to a weight signal reduced in amount by a predetermined correction value.
