摘要： A passenger detection system has an antenna electrode and a guard electrode mounted to a seat bottom of a seat of a vehicle. The passenger detection system further has a power source means for detecting a presence of a passenger on the seat. The power source means applies electric power to the antenna electrode so that a load current flows in the antenna electrode and a weak electric field is generated from the antenna electrode by the load current. The power source means detects an electric current generated in the antenna electrode in response to the electric field. A capacitance between the antenna electrode and a floor of the vehicle is determined based on the detected electric current in a condition that an electric field generated from the antenna electrode on a side of the guard electrode is cancelled by the guard electrode, to thereby detect a passenger on the seat.

摘要： A capacitance type sensor installed in a vehicle includes the first electrode, the second electrode, and the third electrode. The first electrode is arranged inside a seating portion of a seat or a backrest portion of the seat, or both. The second electrode is arranged adjacent to the first electrode inside at least one of the seating portion and the backrest portion of the seat, whatever the first electrode is arranged. The second electrode forms an electric field together with the first electrode between them in a wetness determination mode in which a wet condition of the seat is determined. The third electrode forms an electric field together with the first and the second electrode between them in an occupant determination mode in which an occupant in the seat is determined.
