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. 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. Specifications
