Kia Soul: Yaw-rate and Lateral G Sensor Description and Operation
Kia Soul EV (PS EV) 2015-2020 Service Manual / Brake System / ESP(Electronic Stability Program) System / Yaw-rate and Lateral G Sensor Description and Operation
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 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''s yawing, the ESC control is reactivated.
The lateral G sensor senses vehicle''s lateral G. A small
element inside the sensor is attached to a deflectable lever arm by the
lateral G
Direction and magnitude of lateral G loaded to vehicle can be
known by the change in electrostatic capacity according to lateral G.
