Abstract
A passenger detection apparatus may include: an SBR (Seat Belt Reminder) sensor unit having a plurality of SBR sensors installed in respective seats of a vehicle, and connected in parallel to one another; and a control unit configured to detect a combined resistance value of the SBR sensor unit, compare the detected combined resistance value to resistance values of a combined resistance table which is preset and stored in an internal memory, and determine that a passenger corresponding to each boarding zone of the combined resistance table is on board, when the detected combined resistance value is not included in a grey zone.

A passenger detection apparatus comprising:
- a seat belt reminder (SBR) sensor unit comprising a plurality of SBR sensors disposed respectively at a plurality of seats of a vehicle and connected in parallel;
- and
- a control unit configured to:
- detect a combined resistance value of the plurality of SBR sensors;
- compare the detected combined resistance value to a plurality of preset resistance values of a combined resistance table stored in a data storage;
- and
- determine that a passenger corresponding to each of a plurality of boarding zones of the combined resistance table is on board when the detected combined resistance value is outside a grey zone between the preset resistance values of the combined resistance table.
A method for detecting passengers using a seat belt reminder (SBR) sensor unit comprising a plurality of SBR sensors disposed respectively at a plurality of seats of a vehicle and connected in parallel, the method comprising:
- detecting a combined resistance value of the plurality of SBR sensors;
- comparing the detected combined resistance value to a plurality of preset resistance values of a combined resistance table;
- and
- determining that a passenger corresponding to each of a plurality of board zones of the combined resistance table is on board when the detected combined resistance value is outside a grey zone between the preset resistance values of the combined resistance table.
