Kia Carens: ESP(Electronic Stability Program) System / Yaw-rate and G Sensor Description and operation
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 ESP 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.
The longitudinal G sensor is installed in the yaw-rate sensor.
This longitudinal G sensor detects vertical acceleration of the vehicle, while
the lateral G sensor detects lateral acceleration of the vehicle. The HECU uses
these signals for the Hill start Assist Control function.
