Abstract
The present invention relates to a vehicle passenger detecting apparatus capable of detecting an unoccupied-seat state through the use of existing signals in a vehicle and correcting an unoccupied-seat reference value with a simple configuration. In a case in which an ignition key switch and a buckle switch are in off conditions and a load detecting value, which is the sum of measurement data from load sensors in these conditions, falls below a predetermined unoccupied-seat load value, an occupied-seat reference value serving as a load measurement standard for detection of a state of a vehicle passenger is corrected using the load detection value. This eliminates the influence of vibrations stemming from engine revolutions and electrical noises and enables the reference value to be corrected using a stabler load detection value.
