Kia Optima: Yaw-rate and Lateral G Sensor. Description and Operation - ESC(Electronic Stability Control) System - Brake System - Kia Optima TF 2011-2023 Service ManualKia Optima: Yaw-rate and Lateral G Sensor. Description and Operation

Description

When the vehicle is turning with respect to a vertical axis the yaw rate sensor detects the yaw rate electronically 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.
