Title (DE) VERFAHREN UND VORRICHTUNG ZUR ÜBERTRAGUNG VON DIGITALEN DATEN VON EINER MESSSTATION EINES INSASSENSCHUTZSYSTEMS EINES KRAFTFAHRZEUGS ZU EINEM AIRBAGSTEUERGERÄT
(EN) METHOD AND DEVICE FOR TRANSMITTING DIGITAL DATA FROM A MEASURING STATION IN A MOTOR VEHICLE OCCUPANT PROTECTION SYSTEM TO AN AIR BAG CONTROL DEVICE
(FR) PROCEDE ET DISPOSITIF POUR TRANSMETTRE DES DONNEES NUMERIQUES ENTRE UN POSTE DE MESURE D'UN SYSTEME DE PROTECTION DES OCCUPANTS D'UN VEHICULE A MOTEUR ET UN APPAREIL DE COMMANDE D'AIRBAG
Abstract:
(DE) Bei der Übertragung von digitalen Daten von einer Meßstation (13) zu einem Airbagsteuergerät (12) wird ein zur Energieversorgung der Meßstation dienendes Gleichsignal (I) des Airbagsteuergerätes (12) strommoduliert und dabei nach Maßgabe der zu übertragenden Daten derart verändert, daß sich die Veränderungen des Stroms (I) im zeitlichen Mittel gegenseitig aufheben.
(EN) During the transmission of digital data from a measuring station (13) to an air bag control device (12), a direct current signal (1) of said air bag control device (12) used to provide energy for the measuring station is modulated and modified according to the data which is to be transmitted so that current variations (I) cancel each other out in a temporal average.
(FR) Selon l'invention, lors de la transmission de données numériques entre un poste de mesure (13) et un appareil de commande d'airbag (12), un signal de courant continu (I) de l'appareil de commande d'airbag (12), servant à l'alimentation énergétique du poste de mesure, est modulé et modifié en fonction des données à transmettre, de façon à ce que les variations du courant (I) s'annulent mutuellement dans la moyenne temporelle.
