Abstract
A method of determining an equivalent output value for a failed sensor in a vehicle seat having an occupancy sensing system. The method includes the steps of sensing the output of each sensor in an array of sensors that detect a physical presence in the seat. If the output of the sensor falls below a predetermined value, exceeds a predetermined value, or remains fixed the sensor is classified as inoperative. The method then calculates an equivalent sensor output value for any sensor classified as inoperative and applies the sensor array output values for each operable sensor in the array and the calculated equivalent output value for any inoperative sensor to a neural net. Then, the applied sensor output values are recognizing as falling within one of a group of predetermined classification patterns that represent a physical presence in the seat defined by size, weight, and physical orientation.
