Title:
ANGULAR VELOCITY SENSOR DEVICE AND METHOD FOR CORRECTING ANGULAR VELOCITY SENSOR
Document Type and Number:
Japanese Patent JP2016031283
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an angular velocity sensor device and a method for correcting an angular velocity sensor with which it is made possible to compensate for an offset with high accuracy when using the angular velocity sensor.SOLUTION: An angular velocity sensor device comprises: an angular velocity sensor 10, provided in a moving entity, for detecting an angular velocity when the moving entity has turned in a horizontal direction; an acceleration sensor 20, juxtaposed to the angular velocity sensor 10, for detecting an inclination angle that is referenced to a direction of gravity; a drive unit 30 for rotating both the angular velocity sensor 10 and the acceleration sensor 20 in the direction of gravity or in a direction opposite thereto by a prescribed angle from the horizontal direction; and a processing unit 40 for integrating the angular velocities detected by the angular velocity sensor 10 and calculating a first inclination angle when the angular velocity sensor 10 and the acceleration sensor 20 are rotated by the prescribed angle, and compensating for an angle on the basis of a difference between a second inclination angle detected by the acceleration sensor 20 when the moving entity has turned in the horizontal direction and the first inclination angle.SELECTED DRAWING: Figure 1
