INTELLIGENT SENSOR FOR MAGNET BASED AUTONOMOUS VEHICLE:MAGNETIC POSITION SENSING USING MAGNETIC SENSORS ARRAY

摘要

In this paper, an intelligent position sensor for magnet based autonomous vehicle was described. In the magnetic positioning system, the magnetic field of Earth is a background 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 sensors array included a vertical field' the 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 by the experimental results.
