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 at a plurality of seats of a vehicle, respectively, 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 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 of the combined resistance table.
A method for detecting passengers using a seat belt reminder (SBR) sensor unit comprising a plurality of SBR sensors provided at a plurality of seats of a vehicle, respectively, and connected in parallel to one another, the method comprising:
- detecting a combined resistance value of the SBR sensor unit;
- 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 comparison result between the detected combined resistance value and the combined resistance table indicates that the detected combined resistance value is outside a grey zone of the combined resistance table.
