Vehicle contact sensor has noise sensors on plastic instrument with break locations creating sound used for object location by time difference measurement
A vehicle contact sensor has noise sensors (10, 16) on a plastic instrument (11) containing fibres with designed break locations (18) that generates a noise by cracking on contact with an object (12) which is located by time difference measurements in propagation in the sound conducting layer.
