POSITION MEASURING APPRATUS FOR VEHICLE AND POSITION MEASURING METHOD USING THERE OF

摘要

PURPOSE: A vehicle location measurement method and a vehicle location measurement device using the same are provided to improve the accuracy in the location measurement by measuring the earth magnetism at two or more different axes to grasp a critical point. CONSTITUTION: A sensor unit(110) measures the earth magnetism and measures the earth magnetism according to a movement of a vehicle. A central processing unit(130) controls the sensor unit and measures the location of the vehicle according to the measured value of the sensor unit. The central processing unit measures the location by grasping a critical point of the measured value of the earth magnetism. A communication unit(140) transmits the location of the vehicle measured through the central processing unit to the outside. Two axes of two or more different axes are two difference axes perpendicular to an X-axis.
