Occupant and child seat detection device

摘要

An occupant presence and child seat detection system includes several sensors to assist a capacitance based occupant presence detection system in distinguishing an occupant from a child seat on a wet vehicle seat. In one configuration, capacitance on the seating surface and wetness of the seating surface are measured. The determination of the presence of an occupant is based upon the measured capacitance and the measured wetness.
