Abstract:
1. A system for determining or controlling a relative position of two relatively movable elements, comprising a vehicle container combination and a utility vehicle including an unloading apparatus, characterized in that the system comprises: at least three transmitting devices intended to be fitted, in use, in a predetermined spatial arrangement to one of the two relatively movable elements and configured to transmit respective signals; a single sensor device intended to be fitted, in use, to the other of the two relatively movable elements and configured to receive, and to determine the source direction (.psi..sub.i, .PHI..sub.i) of, the signals transmitted by the transmitting devices; and an electronic processing unit connected to the sensor device and configured to determine the relative position of the two relatively movable elements based on the source direction (.psi..sub.i; .PHI..sub.i) of the signals transmitted by the transmitting devices, and on the spatial arrangement of the transmitting devices; wherein said electronic processing unit is configured to determine the relative position of the two relatively movable elements by: computing a distance (l.sub.
