SUPPLEMENTAL RESTRAINT SYSTEM – AIRBAG SYSTEMRS–15
RS
SYSTEM DESCRIPTION
1. GENERAL
(a) In conjunction with impact absorbing structure for a
frontal collision, the SRS (Supplemental Restraint
System) driver airbag and front passenger airbag
were designed to supplement seat belts in the event
of a frontal collision in order to help reduce shock to
the head and chest. This system is a 3-sensor type
airbag system to detect the impact during a frontal
collision using the center airbag sensor assembly
and front airbag sensors. It also operates the airbag
system and seat belt pretensioner.
(b) In order to detect the extent of the collision during
the initial stages of the collision in further detail, the
front airbag sensors have been changed from
mechanical type to electrical type deceleration
sensors. Accordingly, the deployment of the driver
airbag and front passenger airbag is controlled in
two stages according to the severity of the impact.
(c) In conjunction with impact absorbing structure for a
side collision, the front seat side airbag and curtain
shield airbag were designed to help reduce shock to
the driver, front passenger, and rear outer
passengers in the event of a side collision or
rollover.
(d) RSCA (Roll Sensing of Curtain Shield Airbags) is
used in order to deploy the curtain shield airbags
and the seat belt pretensioner for the driver and
front passenger, in the event that the vehicle rolls
over.
(e) The curtain shield airbag that helps reduce shock to
the front and rear seat occupants with a single
curtain shield airbag has been adopted. In
conjunction with this system, the side airbag
sensors have been installed at the bottom of the
center pillars and the rear airbag sensors have been
installed at the bottom of the rear pillars
respectively.
(f) In this system, a front side collision is detected by
the side airbag sensors in order to deploy the front
seat side airbag and curtain shield airbag. A rear
side collision is detected by the rear airbag sensors
and the center airbag sensor assembly in order to
deploy the curtain shield airbag.
(g) The center airbag sensor assembly sends the
airbag deployment signal to the ECM through BEAN
(Body Electronics Area Network) and CAN
(Controller Area Network) to operate the fuel pump
control.
(h) The center airbag sensor assembly sends the
airbag deployment signal to the body ECU via a
discrete line to operate collision door lock release
control.
