Impact Sensor: Description and Operation
INFLATABLE RESTRAINT FRONT END SENSOR
The front end sensor is equipped on vehicles to supplement the SIR system performance. The front end sensor is electronic and is not part of the
deployment loops, but instead provides input to the SDM. The front end sensor can assist in determining the severity of some frontal collisions. The
SDM uses the input from the front end sensor to assist in determining the severity of a frontal collision further supporting air bag deployment. If the
SDM determines a deployment is warranted, the SDM will cause current to flow through the deployment loops deploying the frontal air bags.
