Abstract:
(EN) The invention relates to a method for operating an ultrasonic measurement device, comprising the steps: receiving echo amplitudes (12); determining object distances for the received echo amplitudes (12); calculating normalised echo amplitudes for the received echo amplitudes (12), a received echo amplitude (12) with a certain object distance being divided by a reference echo amplitude for the same or a similar object distance; coding the normalised echo amplitudes; and transmitting the coded echo amplitudes to a control unit (8). The invention also relates to a computer program and a system for performing the method and to a vehicle (2) having a driver assistance system (4).
(FR) L'invention concerne un procédé pour faire fonctionner un dispositif de mesure à ultrasons, qui comprend les étapes consistant à recevoir des amplitudes d'écho (12), à déterminer des distances à des objets en fonction des amplitudes d'écho (12) reçues, à calculer des amplitudes d'écho normalisées par rapport aux amplitudes d'écho (12) reçues, une amplitude d'écho (12) reçue corrélée à une distance à l’objet définie étant divisée par une amplitude d'écho de référence corrélée à la même distance à l'objet ou à une distance à l’objet similaire, à coder les amplitudes d'écho normalisées et à transmettre les amplitudes d'écho codées à un appareil de commande (8). L'invention concerne en outre un programme informatique et un système permettant la mise en oeuvre dudit procédé ainsi qu'un véhicule (2) équipé d'un système d'aide à la conduite (4).
(DE) Die Erfindung betrifft ein Verfahren zum Betreiben einer Ultraschallmesseinrichtung, umfassend die Schritte des Empfangens von Echoamplituden (12), des Ermittelns von Objektabständen zu den empfangenen Echoamplituden (12), des Berechnens normierter Echoamplituden zu den empfangenen Echoamplituden (12), wobei eine empfangene Echoamplitude (12) mit einem bestimmten Objektabstand durch eine Referenzechoamplitude zu dem gleichen oder ähnlichen Objektabstand dividiert wird, des Kodierens der normierten Echoamplituden und des Übertragens der kodierten Echoamplituden an ein Steuergerät (8). Weiterhin werden ein Computerprogramm und ein System zur Ausführung des Verfahrens angegeben sowie ein Fahrzeug (2) mit einem Fahrassistenzsystem (4).
