Impact Sensor: Description and Operation

SIDE IMPACT SENSOR




The Side Impact Sensors are remote sensor that detect acceleration due to collision at their mounting locations. The primary purpose of the Side Impact Sensors is to provide an indication of a collision earlier than is possible from a central mounting location. The Side Impact Sensors send acceleration data to the central control module.

FRONT IMPACT SENSOR




The Front Impact Sensor is a remote sensor that provides accelerometer data to the advanced restraint control module to determine if the severity of a frontal impact event warrants a single-stage or dual-stage frontal airbag deployment.

Backup power
The advanced restraint control module must provide deployment power to the Front Impact Sensor for a minimum of 150 ms after loss of vehicle power.
