In this paper, a position sensing system for magnet based autonomous vehicle using 1-diemnsional magnetic field sensor array was described. In advanced vehicle control, position sensing is an important task for the identification of their locations, such as the lateral position within a trajectory. The magnet based autonomous vehicle was identified position using magnetic materials. In the magnetic sensing system, the Earth field is a disturbance. It should be estimated a real-time. And, the memory space should be reduced in implementation. To solve the above problems, this paper proposes the magnetic field sensor array system included a vertical component of magnetic field, a linear region of the sensor output, method of position determination using a simple equation with a microcontroller. The proposal is verified practicability for magnetic position sensing system by the experimental results.
