CAPACITIVE OCCUPANT DETECTION SYSTEM HAVING WET SEAT COMPENSATION AND METHOD

摘要

An occupant detection system and method are provided. The system includes a capacitive sensor having an electrode arranged in a seat proximate to an expected location of an occupant for sensing an occupant presence approximate thereto. The capacitive sensor is configured to provide an output indicative of the sensed occupant presence. Occupant detection circuitry is included for processing the capacitive sensor output and determining a wet seat condition and generating a wet seat fault based on a determined wet seat condition. The occupant detection circuitry further detects a state of occupancy of the seat based on the capacitive sensor output and the wet seat fault.
