Abstract: A passenger detection system comprises an antenna electrode, an oscillation circuit, a current detection circuit, a phase difference detection circuit, and a control circuit. The antenna electrode is placed on the upper side of a seat. The oscillation circuit generates a high frequency low voltage oscillation signal in order to generate a weak alternating electric field around the antenna electrode. The current detection circuit detects a transmission current which passes between the oscillation circuit and the antenna electrode according to the weak alternating electric field which is generated around the antenna electrode. The phase difference detection circuit detects the phase difference between the oscillation signal supplied from the oscillation circuit and an output signal which is supplied to the antenna electrode.

Abstract: A passenger detection system including a single antenna electrode mounted on a surface of a passenger seat in an automobile. An oscillator generates an AC current having a predetermined voltage amplitude that is transmitted to the antenna electrode to produce a minute electric field around the antenna electrode. An amplitude control circuit is used to control the voltage amplitude of the output signal from the oscillator. The electrical characteristics of an object on the passenger seat alter the current and phase of the signal in the antenna electrode. A current detection circuit detects the amount of current flowing from the oscillator to the antenna electrode. In addition, a phase differential detection circuit detects a phase differential between the output signal from the oscillator and the signal on the antenna electrode.
