GYRO SENSOR FUNCTION
CHU092066902S03
•
The gyro sensor is located in the navigation unit. The sensor converts yaw rate, which is one of the inputs used
in calculating the vehicle’s direction of travel from the vehicle’s cornering angle, into electrical signals. It then
sends these signals to the navigation unit.

GYRO SENSOR CONSTRUCTION/OPERATION
CHU092066902S04
•
A piezoelectric type (utilizes the piezoelectric effect) gyro sensor is used. It is composed of three piezoelectric
transducers, a drive transducer and two pick-ups, used to drive and sense the vibrations of the triangular pillar.
Both parts are installed on each surface of the triangle pillar. Piezoelectric transducer can either be distorted by
electrical voltage, or can create electrical voltage by being distorted. The gyro sensor uses both characteristics
of the piezoelectric material.
•
One face of the triangular pillar functions as the driving side, the others function as pick-up sides. Electrically
induced vibration of the drive transducer causes the pick-up sides to vibrate, and the pick-up sides produce an
electrical current.
