Abstract
A passenger detection apparatus includes sensors arranged on a seat in a vehicle; shield cables corresponding to the sensors, wherein one end the core wire is connected to the corresponding one of the sensors; a measurement signal output device for outputting a measurement AC signal; a device for detecting a current output from the measurement signal output device; a device for outputting a capacitance canceling AC signal, which has the same phase and the same level as those of the measurement AC signal; a device for selectively applying one of the measurement AC signal and a DC voltage to the other end of each shield cable; and a device for selectively applying one of the capacitance canceling AC signal and a second signal, which has a different waveform from that of the measurement AC signal, to the shield of each shield cable.
