A passenger identification apparatus for vehicles is provided to identify a passenger through integration of a sensor that senses change in permittivity and a sensor that senses change in pressure. The apparatus includes a permittivity change sensing unit that is installed in the seat and senses change in capacitance generated by permittivity of the passenger seated on the seat and a pressure change sensing unit that is installed in the seat and senses change in pressure generated by a load of the passenger seated on the seat. A controller adjusts power supplied to the permittivity change sensing unit and the pressure change sensing unit and determines whether the passenger is seated on the seat and the type of passenger using permittivity and pressure change values sensed by the permittivity change sensing unit and the pressure change sensing unit.

Passenger identification apparatus for vehicles

An occupant classification apparatus configured for classifying an occupant seated in a seat based on capacitance of and the amount of moisture contained in the occupant is disclosed. The occupant classification apparatus includes an electrode device for detecting an occupant seated in a seat, an occupant property measurement device for measuring capacitance of and the amount of moisture contained in the occupant detected by the electrode device, and a controller configured for estimating the occupant based on the capacitance and the amount of moisture measured by the occupant property measurement device.

Occupant classification apparatus

The present invention provides an occupant classification apparatus for a vehicle. The occupant classification apparatus for a vehicle includes a sensor mat that is mounted on each seat in the vehicle to sense objects disposed on the seats. An impedance measurer is configured to measure a current based on impedance of the object using the sensor mat A controller is configured to analyze the current measured by the impedance measurer and estimate the object that corresponds to the analyzed result.

Occupant classification apparatus for vehicle

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.
