2129673 9316397 PCTABS00025 An electromagnetic detection system mainly for signalizing not visible obstacles during vehicle parking operation. The system comprises a transmitting-receiving mean (F) of radiofrequency field consisting of two wires or strips of electrically conductive material (antenna) coupled together; a mean (T) capable of creating, all around said transmitting-receiving mean, an electromagnetic radiofrequency field; a mean (R) capable of detecting the variations of said electromagnetic field produced by an object approaching the said transmitting-receiving mean; a mean (S) capable of signalizing such variations with an acoustic or view signal. Advantages: detection of the obstacles approaching the vehicle with absolute continuity for all the extension of the part which has to be protected (for example the bumper); detection of the obstacles not depending on their physical properties as shape, dimensions, density and reflective property, continuity of the obstacles detection from the maximum detection distance up to the contact without the blind zone (30-40 centimeters before the contact) which characterizes the prior art systems.
