VELOSTER(FS) >2013 > G 1.6 GDI > Brake System > ESC(Electronic Stability Control) System > Yaw-rate and Lateral G Sensor>Description and Operation | ![]() ![]() |
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.
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.
