LR3/Disco 3
The occupant classification system can determine if the front passenger seat is unoccupied, occupied by a small person,
or occupied by a large person. The occupant classification system consists of:
A pressure pad, installed under the cushion of the front passenger seat, which is connected to a pressure sensor.
A safety belt tension sensor, integrated into the anchor point of the front passenger safety belt.
An occupant classification module, installed under the front passenger seat.
The pressure pad is a silicone filled bladder. Any load on the pressure pad is detected by the pressure sensor.
The safety belt tension sensor is a strain gauge that measures the load applied by the safety belt anchor to the anchor
bolt.
The occupant classification module supplies a reference voltage to the pressure sensor and the safety belt tension sensor
and, from the return signals, measures the loads acting on the pressure pad and the safety belt tension sensor. The load
