摘要

"Apparatus for use in the orientation direction of a vehicle hired and method used in the driving of the vehicle hired.It is revealed a system used for driving a vehicle on a highway along an elongated guide element which emits a magnetic field.Including an upper and a lower sensor sensor connected to the vehicle. The lower sensor detects a magnetic field emitted by the element guide is elongated and a magnetic field environment.The upper sensor detects only the magnetic field environment.The signals produced by the detector is processed to subtraction of the signal of the sensor above the sensor signal to produce a signal below guidance of direction for the transmitWent to an automatic steering system in vehicle.
