Abstract

An apparatus of compensating for a sensing value of a gyroscope sensor, a system having the same, and a method thereof are provided. The apparatus includes a gyro bias compensator that eliminates a gyro bias from the gyro sensing value, which is received from a gyroscope sensor, through map matching between a detailed map and vehicle surrounding data which is acquired, and a gyro scale factor compensator that calculates a gyro scale factor by calculating a heading angle variation of a road, on which a vehicle is traveling, by using the detailed map when the vehicle is turning, and compensatesfor the gyro sensing value by using the calculated gyro scale factor.

Description

[0001] Cross-references to related applications [0002] This application is based upon and claims the benefit of priority from Korean Patent Application No. 10-2017-0137709 filed with the Korean Intellectual Property Office on October 23, 2017, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to an apparatus for compensating a sensing value of a gyro sensor, a system having the same, and a method thereof, and more particularly, to a technology capable of compensating a gyro sensor through a sensor map mapping manner supported by vehicle driving. Background technique [0004] Generally, various moving bodies such as ships, airplanes, and automobiles are equipped with a positioning system for recognizing a current position and a current moving speed to determine a moving path. The positioning system receives radio waves indicating latitude, longitude, altitude, etc. from multiple global positi...
