Abstract
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.
