Abstract Disclosed are a device for positioning a vehicle and a method thereof. The device for positioning a vehicle comprises: a first sensing unit detecting driving state information of a vehicle; a GPS module acquiring position data of the vehicle; a safety core unit generating a first driving trajectory in which the vehicle has traveled based on the driving state information detected by the first sensing unit, and estimating the current position of the vehicle based on the generated first driving trajectory; a second sensing unit detecting driving environment information of the vehicle; and a performance core unit generating a second driving trajectory in which the vehicle has traveled, generating map matching data by performing map matching with respect to the driving environment information detected by the second sensing unit, and generating fusion positioning information by fusing the position data received from the GPS module, the second driving trajectory, and the map matching data. Here, the performance core unit is characterized by individually generating and providing: the position data generated by means of the map matching data; a map matching covariance value generated when the position data received from the GPS module and the position data by the second driving trajectory are fused; a GPS covariance value; and a DR covariance value. 본 발명은 차량의 측위 장치 및 그 방법이 개시된다. 본 발명의 차량의 측위 장치는, 차량의 주행 상태 정보를 검출하는 제1 센싱부; 상기 차량의 위치 데이터를 획득하는 GPS 모듈; 상기 제1 센싱부에 의해 검출된 주행 상태 정보에 근거하여 상기 차량이 주행한 제1 주행 궤적을 생성하고, 상기 생성된 제1 주행 궤적에 기초하여 상기 차량의 현재 위치를 추정하는 세이프티 코어부; 상기 차량의 주행 환경 정보를 검출하는 제2 센싱부; 및 상기 차량이 주행한 제2 주행 궤적을 생성하고, 상기 제2 센싱부에 의해 검출된 주행 환경 정보에 대하여 맵매칭을 수행하여 맵매칭 데이터를 생성하며, 상기 GPS 모듈로부터 전달받은 위치 데이터, 상기 제2 주행 궤적 및 상기 맵매칭 데이터를 융합하여 융합 측위 정보를 생성하는 퍼포먼스 코어부;를 포함하되, 상기 퍼포먼스 코어부는, 맵매칭 데이터에 의한 위치 데이터, GPS 모듈로부터 전달받은 위치 데이터 및 제2 주행 궤적에 의한 위치데이터를 융합할 때 맵매칭 공분산값, GPS 공분산값 및 DR 공분산값을 각각 생성하여 제공하는 것을 특징으로 한다.
