In this paper, a development of magnetic position meter for unmanned ground vehicle or automated vehicle system using two-wired-interface(TWI) communication is presented. Usually, a magnetic position meter is installed under the bumper of an automated vehicle to detect magnetic markers or magnetic wire. The previous developed magnetic position meter is composed of several sub-boards with magnetic sensors, which use the parallel communication with each board. In order to overcome the limitation and minimize the size of the magnetic position meter, a serial communication should be applied. In this paper, we apply TWI communication to the board of magnetic sensors. The developed magnetic position meter is installed on the automated vehicle, and shows the high performance in the automatic driving test.
