Patent number: 7614314Abstract: An apparatus for classifying a vehicle occupant to determine whether to deploy an airbag is disclosed. The classification apparatus includes a sensor which is installed in a seat of a vehicle and is supplied with AC power, the sensor having a sensing conductor and a guard conductor electrically connected to each other, with an insulator interposed therebetween. A controller compares an imaginary current value, attributable to variation in capacitance of the sensor, measured on an output side of the sensor, and a real current value, attributable to variation in resistance of the sensor, with preset threshold values, thus classifying an occupant who is sitting in the seat. According to the classification apparatus, even if moisture permeates into a seat, an occupant can be precisely classified using the real current value and the imaginary current value.Type: GrantFiled: January 10, 2008Date of Patent: November 10, 2009Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Chun Seok Park, Jae Haeng Yoo
