Abstract
A method for the classification of an occupancy status of a vehicle seat, where occupancy profiles from an occupancy sensor are recorded and evaluated and the classification of the actual occupancy status is determined. The method includes, when the system power is turned off, storing the last determined class and the last recorded profile into a non-volatile memory; when the system power is turned on, comparing the first recorded profile with the profile stored into the non-volatile memory; and if the likeness of the first recorded profile and the profile stored in the non-volatile memory exceeds a specific threshold, setting the actual class to equal the class stored into the non-volatile memory.
