Abstract

Circuit d'exploitation et de commande de transducteurs de son (101) appliqué à des systèmes d'assistance aux manoeuvres de rangement d'un véhicule automobile et comprenant un premier transformateur (103) avec un primaire (104, 105) et un secondaire (106) avec un rapport de transformation u > 1.Le secondaire (106) comporte des branchements (5) pour un transducteur de son (101).Les moyens fournissent une tension variable dans le temps appliquée aux primaires (104, 105).Un autre transformateur (104) découplé très largement du premier transformateur est monté de façon que les secondaires (106) des transformateurs soient reliés au branchement (5) du transducteur (101).
