Hyundai Elantra HD: Occupant Classification Sensor (OCS). Description and Operation
Description
In contrast to the initial one-stage airbag systems, newer
restraint systems involve complex logic to select, or alternatively suppress,
various levels of safety system deployment. Inherent to an Advanced Restraint
System is the ability to discern information regarding passenger occupancy.
It is intended that these inputs be provided through the OC system.
The object of such safety system is to reduce the risk and
level of injuries by automatically adapting the airbag(s) and seat belt pretensioner
to the driving status of the vehicle, its occupants, and the crash severity.
The current OC system covered in this specification continually senses and classifies
the front passenger side seat. The Occupant Classification System described
in this section is Weight Classification System (WCS) of strain gauge type.
It consist of 4 weight sensors and ECU which is classifying weight of occupant.
It is installed on the seat leg assembly.
