Hyundai Sonata: Weight Classification System (WCS). 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 WCS.
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 WCS
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 2 weight sensors
and ECU which is classifying weight of occupant. It is installed on the seat
track assembly.
