•
The pick-up sides are distorted by Coriolis force
*
, which happens as a result of the turning arc and its effect on
the center axis of the sensor pillar. Two piezoelectric pick-up sides convert the distortion amount into two
electrical signals to indicate the exact yaw ratio.
*
Coriolis force:If turning velocity is added to an already-moving object, force is produced at a right angle to the
object's path of travel.

AUTONOMOUS NAVIGATION OPERATION
CHU092066902S05
•
The navigation unit detects the position of the vehicle from a cumulative calculation of the vehicle's direction
and travelled distance based on the processing of direction data obtained from the gyro sensor and vehicle
speed signals obtained from the speedometer sensor (built into microcomputer inside instrument cluster).
•
Even when GPS satellite reception is not available, accurate detection of vehicle's position is still possible.
•
Signals from GPS satellites are used partially for detecting direction data.

•
GPS is a navigation system developed by the U.S. Department of Defence. The system has GPS satellites
orbiting the earth at an altitude of approximately 21,000 km {13,000 miles}.
