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.
Claims7
A passenger detection system for a person on a seat of a vehicle, comprising:
- a first capacitance sensor for measuring a first capacitance between a seating portion of the seat and a body of the vehicle;
- a second capacitance sensor for measuring a second capacitance within the seat;
- and
- a detection unit which detects a passenger on the seat based on the measured first capacitance and the measured second capacitance.
