Abstract

According to a method and a device for determining the orientation of a vehicle relative to a guidance loop (L) a loop signal (SL) is generated by a signal generating device. The loop signal has at least two main electrical states. The vehicle may exhibit a first and second orientation, the second orientation being opposite to the first, relative to the guidance loop (L). The loop signal (SL) is sensed by an antenna device (ANT), and an orientation signal (D<*>) is generated by means of a directional decoder (DEC), the orientation signal assuming a first orientation state and a second orientation state depending upon the main electrical state of the loop signal (SL) which is sensed by the antenna device (ANT). The first and second orientation states correspond respectively to the first and second orientations of the vehicle.
