Occupant classification system with seat back sensor

摘要

A classification system for determining the occupancy state of a seat of a vehicle. The classification system includes a first sensing electrode located in a back portion of the seat and a second sensing electrode located in a base portion of the seat. The system includes a measurement circuit configured to measure a first property associated with the first sensing electrode and a second property associated with the second electrode. A controller is configured to send an occupancy signal indicative of the occupancy state of the seat based on the measured properties associated with the first and second sensing electrodes. The controller may be configured to send the occupancy signal to a Seat Belt Reminder (SBR) system.

1. A classification system, for determining the occupancy state of a seat of a vehicle, the system comprising:
a first sensing electrode located in a back portion of the seat; a second sensing electrode located in a base portion of the seat; a measurement circuit configured to measure a first property associated with the first sensing electrode and a second property associated with the second electrode; and a controller configured to send an occupancy signal indicative of the occupancy state of the seat based on the measured properties associated with the first and second sensing electrodes; wherein when the second property associated with the second electrode in the base portion of the seat is indicative of no occupant being located on the base portion of the seat, then the occupancy signal indicates no occupant is located on the seat regardless of the first property associated with the first electrode in the back portion of the seat.
