Impact Sensor: Description and Operation
Side
SIDE IMPACT SENSOR (SIS)
DESCRIPTION
The release system for the front airbag consists of a SRSCM installed in the middle of the vehicle and two front impact sensor (FIS) which are located in
front of the vehicle. Only the SRSCM is capable of releasing the airbags or the seat-belt pretensioner system in the vehicle. In the dialog between the
SRSCM and the front impact sensor it is the SRSCM which takes the release decision. The SRSCM is supported in connection with the front airbag
function by the two front impact sensor, which act as intelligent acceleration sensors and as such back up the central airbag controller. Both the front
impact sensors continuously report the current system status of the vehicle to the SRSCM.
If one of the two front impact sensor reports an acceleration level, the SRSCM must verify the acceleration signal internally by means of a suitable
plausibility check. The SRSCM does not release the appropriate airbag unless the result of this verification is positive.
