Abstract

본 발명은 차량항법장치의 좌표보정방법에 관한 것으로서, 특히 일정시간간격으로 위성정보를 수신하는 단계; 차량속도센서를 통하여 상기 일정시간동안에 차량의 이동거리를 구하는 단계; 차량의 이전 좌표값이 있는 가를 체크하는 단계; 상기 수신된 위성정보 중 차량의 이동거리와 상기 구해진 차량의 이동거리를 비교하여 그 차가 기준치 이상인가를 체크하는 단계; 기준치 이상으로 편차가 심한 경우에는 차량의 현재좌표값을 상기 구해진 차량의 이동거리를 이용하여 계산하는 단계; 및 이전 좌표값이 없거나 편차가 기준치 이하인 경우에는 수신된 위성정보에 포함되어 있는 새로운 좌표값으로 현재 차량의 좌표값을 결정하는 단계를 구비하는 것을 특징으로 한다.The present invention relates to a coordinate correction method of a vehicle navigation apparatus, and in particular, receiving satellite information at a predetermined time interval; Obtaining a moving distance of the vehicle during the predetermined time through a vehicle speed sensor; Checking whether there is a previous coordinate value of the vehicle; Comparing the moving distance of the vehicle with the obtained moving distance among the received satellite information and checking whether the difference is greater than a reference value; Calculating a current coordinate value of the vehicle using the calculated moving distance of the vehicle, when the deviation is more than a reference value; And determining the coordinate value of the current vehicle by using the new coordinate value included in the received satellite information when the previous coordinate value does not exist or the deviation is less than the reference value.
