The present invention relates to an automatic control system for an agricultural working vehicle and, more specifically, to an automatic control system for an agricultural working vehicle, capable of producing applied vehicle information using real-time vehicle information sensed while work is performed and preliminary vehicle information produced in advance in an agricultural working vehicle on a work place to control the agricultural working vehicle working in the work place and of controlling work performance of the agricultural working vehicle using the generated preliminary vehicle information and the applied vehicle information, thereby efficiently performing the work in the work place. According to the present invention, the automatic control system on the agricultural working vehicle (1) performing the work in the work place includes: a position sensor unit (100) generating position information on the agricultural working vehicle (1)； a vehicle information sensor unit (200) generating the real-time vehicle information on the agricultural working vehicle (1) while the agricultural working vehicle (1) performs the work in the work place； a vehicle information providing unit (300) obtaining the preliminary vehicle information on the agricultural working vehicle (1) generate in advance on the work place and providing the applied vehicle information in which the preliminary vehicle information is renewed using the real-time vehicle information； and a control unit (400) measuring the position of the agricultural working vehicle (1) in the work place using position information generated in the position sensor unit (100) and controlling the work performance of the agricultural working vehicle (1) in the work place using the applied vehicle information provided from the vehicle information providing unit (300).본 발명은 농작업차량 자동제어 시스템에 관한 것으로, 보다 구체적으로는 작업지에서 작업을 수행하는 농작업차량을 제어함에 있어, 상기 작업지에 대하여 상기 농작업차량에서의 미리 생성된 사전차량정보 및 작업을 수행하는 동안 감지되는 실시간차량정보를 이용하여 적용차량정보를 생성하고, 이를
