Abstract

The invention concerns an ultrasound parking aid system which emits warning signals when an echo signal lying within an audibility window exceeds a given threshold value. Hitherto, an audibility window or the sensitivity of the system was adapted to fixed data of the vehicle and/or the roadway. According to the invention, the sensitivity, audibility window or even the emission response is adapted as a function of varying dynamic data of the vehicle or roadway.
