TIBURON(GK) >2008 > G 2.0 DOHC > Restraint > Supplemental Restraint System Control Module (SRSCM) > Occupant Classification Sensor (OCS)>Description and Operation | ![]() ![]() |
The system is intended
to classify the occupancy status of the front passenger seat in a motor
vehicle based upon the measured force on the bottom seat
cushion.
The system also
communicates to the SRSCM whether to allow or inhibit the deployment of
the passenger airbags and/or pretensioner based upon this
status.
The system should not be
confused with an occupant position recognition system, or any other
occupant proximity sensor.
The Passenger Occupant
Detection System (PODS) utilizes bladder placed between the passenger seat
cushion and suspension to measure the occupant's loading force on the
vehicle seat. The bladder is connected to pressure sensor and ultimately
to an electronic control unit (ECU), both of which are mounted under the
seat pan. The quantitative force determined by the system is compared to a
given threshold for determination of passenger airbag
suppression. |
