Zusammenfassung:	Provided is a vehicle-mounted terminal capable of ETCS file update through linkage with a head unit in a vehicle. The vehicle-mounted terminal comprises: a CAN circuit unit transmitting data to and receiving data from a head unit based on CAN communication; and an ETCS circuit unit receiving a predetermined ETCS file to be updated from the head unit, storing the ETCS file to be updated in a first memory which is an updating area, performing corresponding update based on the ETCS file to be updated, and executing the ETCS file by booting a second memory, which is an execution area, when the update is finished. 차량 내 헤드유닛과의 연동을 통해 ETCS 파일 업데이트가 가능한 차량 탑재 단말기가 제공된다. 상기 차량 탑재 단말기는 상기 헤드유닛과 CAN 통신을 기반으로 데이터를 송수신하는 CAN 회로부, 및 상기 헤드유닛으로부터 소정의 업데이트 대상 ETCS 파일을 수신하고, 상기 업데이트 대상 ETCS 파일을 업데이트 영역인 제1 메모리에 저장하고, 상기 업데이트 대상 ETCS 파일에 기반하여 상응하는 업데이트를 수행하고, 상기 업데이트가 완료됨에 따라 실행 영역인 제2 메모리를 부팅시켜 상기 ETCS 파일을 실행시키는 ETCS 회로부를 포함한다.
