|
The primary purpose of
the SRSCM (Supplemental Restraints System Control Module) is to
discriminate between an event that warrants restraint system deployment
and an event that does not. The SRSCM must decide whether to deploy the
restraint system or not. After determining that pretensioners and/or
airbag deployment is required, the SRSCM must supply sufficient power to
the pretensioners and airbag igniters to initiate deployment.
The SRSCM determines
that an impact may require deployment of the pretensioners and airbags
from data obtained from impact sensors and other components in conjunction
with a safing function.
The SRSCM will not be
ready to detect a crash or to activate the restraint system devices until
the signals in the SRSCM circuitry stabilize.
It is possible that the
SRSCM could activate the safety restraint devices in approximately 3
seconds but is guaranteed to fully function after prove-out is
completed.
The SRSCM must perform a
diagnostic routine and light a system readiness indicator at key-on. The
system must perform a continuous diagnostic routine and provide fault
annunciation through a warning lamp indicator in the event of fault
detection. A serial diagnostic communication interface will be used to
facilitate servicing of the restraint control
system. |
