An occupant sensing ECU determines an occupant state on a seat by comparing occupant determination threshold values with a corresponding sensed load data value, which is originated from load sensors. The ECU stores an adjustment value, which is used to adjust a predetermined design value of each of the occupant determination threshold values. The adjustment value is a difference between an empty-state 0 point load value and a predetermined design value of the empty-state 0 point load value.

Occupant sensing system and adjustment method thereof

A passenger detection device for a vehicle is provided with multiple load sensors, each of which detects a load on a seat of the vehicle within a predetermined detection range of the load sensor, and an ECU that determines passenger information of the seat. The ECU has at least one calculation range, each of which limits the detection range of each corresponding one of the multiple load sensors. The ECU determines the passenger information based on a detection data value of each load sensor, which is outputted from the load sensor and falls within the corresponding calculation range of the load sensor.

Passenger detection device

Each front sensor senses a load, which is applied to a front part of a seat, and each rear sensor senses a load, which is applied to a rear part of the seat. A size of an entire load sensing range of each front sensor is smaller than a size of an entire load sensing range of each rear sensor.
