ABSTRACT:
The present invention refers to a system for detecting obstacles for vehicles, comprising at least one sensor able to transmit a detection signal and to receive an echo signal reflected off at least one obstacle, means of parametric evaluation of said received echo signal which comprise means of comparison between at least two successive echo signals for the determination of a reference echo signal able to define the position of at least one fixed obstacle with respect to said at least one sensor.
