Rollover Control

1. When the vehicle starts to rollover, the angular rate sensor in the SAS control module detects the vehicle rolling

angle speed, and the low-G sensor in the SAS control module detects lateral and vertical accelerations.

2. When the angular speed detected by the angular rate sensor exceeds the specification, an initial rollover

condition is determined and the operational circuit calculates the rolling angle based on the angular speed

detected by the angular rate sensor.

3. When the rollover control operation conditions of angular speed and rolling angle are met and the vehicle is

determined to be in a rollover condition based on the acceleration detected by the low-G sensor, an electronic

signal is output to the output signal circuit.

4. The output signal circuit completes an ignition circuit, and an operation (deployment) signal is sent to the air

bag module and pre-tensioner seat belts indicated in the table below.
