If one operator can drive more than two agricultural machines at the same time, it will be possible to save time and labor for farming. In this paper, an automatic follow-up vehicle system (AFVS) which allows one operator to utilize more than two machines simultaneously is presented. In this system the vehicle controlled by a computer can chase the vehicle driven by a human operator at a constant relative position. It is necessary to measure the relative position between two vehicles exactly in this system. Two ultrasonic sensors and an infrared sensor were used for measurement of the relative position between vehicles. The paper describes the outline and the accuracy of the measuring instrument.
