Kia Sorento: Yaw-rate and G Sensor Description
Second Generation XM (2011-2023) / Kia Sorento XM 2011-2023 Service Manual / Brake System / ESC(Electronic Stability Control) System / Yaw-rate and G Sensor Description
The yaw rate and G sensor is included inside the air bag control module
(SRSCM).
When the vehicle is turning with respect to a vertical axis the yaw rate
sensor detects the yaw rate electroniclly by the vibration change of plate fork
inside the yaw rate sensor.
If yaw velocity reaches the specific velocity after it detects the vehicle'yawing,
the ESC control is reactivated.
The later G sensor senses vehicle's lateral G. A small element inside
the sensor is attached to a deflectable leverarm by later G.
Direction and magnitude of lateral G loaded to vehicle can be known with
electrostatic capacity changing according to lateral G.
