System to analyse the surroundings of a vehicle, related method and control device

摘要

The vehicle (10) may have four proximity sensors (12-15) on its end. The distances (a) between the first and second (b) between the second and third and (c) between the third and fourth are all different. Signals from the sensors are passed to a control circuit (11) with a memory (17) and a calculating circuit (18). The control circuit is connected to an audio-visual alarm (16).
