Passenger detection system
First Claim
1. A passenger detection system for detecting a sitting of a passenger on a seat of a vehicle, the passenger detection system comprising:
- a capacitive passenger detection electrode which is embedded in the seat to detect the sitting;
a surface unit which is attached to an upper exterior surface of the seat, at least a covering portion of the surface unit being rendered electrically conductive,the passenger detection electrode being covered with the covering portion;
a driving unit which applies a voltage between the passenger detection electrode and a GND of the vehicle; and
a detection unit for detecting a capacitance between the passenger detection electrode and the vehicle GND.

Abstract
A passenger detection system for detecting a sitting of a passenger on a seat of a vehicle has a capacitive passenger detection electrode which is embedded in the seat to detect the sitting, a surface unit attached to an upper surface of the seat, a driving unit which applies a voltage between the passenger detection electrode and a vehicle GND, and a detection unit for detecting a capacitance between the passenger detection electrode and the vehicle GND. At least a covering portion of the surface unit is rendered electrically conductive. The passenger detection electrode is covered with the covering portion. Thus, a sitting of the seat can be substantially detected by the passenger detection system.
