  • recognizing the pressure sensors as matrix elements that include active and inactive matrix elements as a function of a load on the vehicle seat;

    generating a seat profile;

    generating a first one of result matrices from the inactive and active matrix elements;

    generating further result matrices from existing result matrices in accordance with a logical operation;

    subjecting adjoining matrix elements to the logical operation for the matrix elements;

    for each individual one of the generated result matrices, generating a sum from the active matrix elements thereof;

    weighting each sum by a corresponding factor, the weighted sums of the generated result matrices forming an operation parameter; and

    performing the passenger classification in accordance with the operation parameter.
