Abstract

The transmission arrangement includes an operating unit that is either manually of programme-controlled, and produces signals for the control of drive motors. These signals are processed by a micro-processor, and at least one second micro-processor receives the processed signal, emitting processed data from one or more television cameras and one or more drive motors. Signal carriers transmit information in singal form between the micro-processors. Tehe micro-processors process received signals to digital form, storing them in an intermediary memory. They then transmit them in strict sequence, and the signal carriers comprises transmitters/receivers fitted on the vehicle chassis and load bearer for wireless consecutive communication between the micro-processors. Woth a certain delay, the micro-processors transmit, via the transmitter/receiver arrangement, echoes of the received signals and compare the respective echoe with the corresp. original signals so that transmission can be controlled, and time measurement components measure the time between a signal transmission and its receipt as an echo. This enables the processor to calculate the distance between the two transmitters/receivers.
