PPD - Passenger Presence Detection Sensor: Description and Operation
The passenger presence detection system detects the presence of passenger in the seat. The system is designed primarily to prevent replacement of airbag
components that fire needlessly in an accident. The PPD system consists of a weight sensor and an interface unit.
The threshold for PPD is:
Occupied (15 kg)
Not occupied (0.6 kg)
The sensor characteristics is defined
RP <= 50 k Ohms for W >= 15 kg
RP > 50 k Ohms for W < 0.6 kg
(RP = Resistance of force sensing resistor)
(W = Mass of weight)
