Kia Sportage: Yaw-rate and Lateral G Sensor: Description and Operation
Third generation SL (2010–2016) / Kia Sportage SL Service & Repair Manual / Brake System / ESC(Electronic Stability Control) System / 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.
