System Operation
AIR BAGS, SEAT BELT PRE-TENSIONER AND LAP PRE-TENSIONER
In case of a frontal collision, when the front impact sensors inside the engine room and the G-sensor inside SRS-
ECU simultaneously detect an impact that exceeds a certain threshold (turned ON), SRS-ECU energizes the
driver's and passenger's (front) air bag modules (squibs), knee air bag module (squib), driver's and passenger's
seat belt pre-tensioners (squibs) and lap pre-tensioner (squib), thus deploying the air bags and triggering the
seat belt pre-tensioners. Also, the advanced air bag has been adopted to optimize the air bag deployment control
by adjusting the inflation pressure.
The seat slide sensor to detect the driver's seat position judges the deployment in two stages, and deploys the
driver's air bag.
The occupant classification-ECU has been added to recognize the passenger's seat occupant. The occupant
classification-ECU identifies the occupant class based on the signals from occupant classification sensor, and
sends the signal to SRS-ECU.
