Description And Operation: Description: Notes
The yaw rate and G sensor unit is integrated in the airbag 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 a certain velocity after detecting the vehicle"s yawing, the ESC control if reactivated.
The lateral G sensor senses vehicle"s lateral G. A small element inside the sensor is attached to a deflectable lever arm by lateral G.
Direction and magnitude of lateral G loaded to vehicle can be known with electrostatic capacity changing according to lateral G.
