Patent abstract
A passenger detection system for a person on a seat of a vehicle, includes a long range capacitance sensor for measuring a long range capacitance between a seating portion of the seat and a body of the vehicle and a short range capacitance sensor for measuring a short range capacitance in the seat, and a detection unit for detecting a passenger on the seat based on the measured long range capacitance and the measured short range capacitance. Therefore, the passenger detection system accurately detects a passenger on the seat of the vehicle while suppressing a detection error caused by an external effect.
