Abstract
A method of calibrating sensitivities of a plurality of pressure sensing cells are disposed at a passenger seat to detect presence of a vehicle passenger. The method is comprised of the following steps: pressing a presser against the passenger seat; detecting output signal levels of the sensing cells; andadjusting sensitivity of the pressure sensing cells according to the output signal levels while the presser is pressed against the seat.
