OCCUPANT POSITION DETECTION DEVICE AND AIRBAG DEPLOYMENT CONTROL SYSTEM
First Claim
1. An occupant position detection device disposed inside a vehicle to detect a position of an occupant, the occupant position detection device including:
- a first detector comprising two or more sensor electrodes disposed forward of a seat and at least one sensor electrode disposed at a position more rearward and higher than these sensor electrodes, the first detector respectively outputting a detection signal based on a distance between each of the sensor electrodes and the occupant; and
a computation unit inputted with the detection signal to compute an occupant position,the computation unit selecting from each of the detection signals outputted from the first detector three or more types of combinations configured from two of the detection signals, calculating a ratio or difference for each of these combinations of detection signals, and computing the occupant position based on the three or more calculated ratios or differences of the detection signals.

Abstract
An occupant position detection device is an occupant position detection device disposed inside a vehicle to detect a position of an occupant, and includes: a detector comprising two or more sensor electrodes disposed forward of a seat and at least one sensor electrode disposed at a position more rearward and higher than these sensor electrodes, the detector respectively outputting a detection signal based on a distance between each of the sensor electrodes and the occupant; and a computation unit inputted with the detection signal to compute an occupant position. The computation unit selects from the detection signals outputted from the detector three or more types of combinations configured from two of the detection signals, calculates a ratio or difference for each of these combinations of detection signals, and computes the occupant position based on the three or more calculated ratios or differences of the detection signals.
