Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur Datenkommunikation in einem Fahrzeug (1) zwischen einer fahrzeuginternen Einrichtung (5, 6, 7) und einem mobilen, mit dem Fahrzeug (1) gekoppelten Gerät (8), bei dem die fahrzeuginterne Einrichtung (5, 6, 7) Daten über einen Datenbus (4) des Fahrzeugs (1) an eine fahrzeuginterne Datenkommunikationsvorrichtung (2) überträgt, wobei ein erstes Datenprotokoll verwendet wird, bei dem eine Arbitrierung erfolgt, die Datenkommunikationsvorrichtung (2) die Daten konvertiert und die Datenkommunikationsvorrichtung (2) die konvertierten Daten über eine Datenverbindung an das mobile Gerät (8) überträgt. Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass bei der Datenübertragung von der fahrzeuginternen Datenkommunikationsvorrichtung (2) an das mobile Gerät (8) ein zweites Datenprotokoll verwendet wird, bei dem keine Arbitrierung erfolgt. Ferner betrifft die Erfindung eine Datenkommunikationsvorrichtung (2), mit welcher das erfindungsgemäße Verfahren ausführbar ist.
(EN)
The present invention relates to a method for data communication in a vehicle (1) between a vehicle-internal device (5, 6, 7) and a mobile appliance (8) that is coupled to the vehicle (1), in which the vehicle-internal device (5, 6, 7) transmits data to a vehicle-internal data communication apparatus (2) via a databus (4) in the vehicle (1), wherein a first data protocol is used, in which arbitration takes place, the data communication apparatus (2) converts the data and the data communication apparatus (2) transmits the converted data to the mobile appliance (8) via a data link. The method according to the invention is characterized in that the data transmission from the vehicle-internal data communication apparatus (2) to the mobile appliance (8) involves the use of a second data protocol, in which no arbitration takes place. In addition, the invention relates to a data communication apparatus (2) which can be used to carry out the method according to the invention.
(FR)
La présente invention concerne un procédé de communication de données dans un véhicule (1) entre un équipement interne du véhicule (5, 6, 7) et un appareil mobile (8) couplé avec le véhicule (1), dans lequel l'équipement interne du véhicule (5, 6, 7) transmet des données sur un bus de données (4) du véhicule (1) à un dispositif de communication de données (2) interne au véhicule. Un premier protocole de données est utilisé avec arbitrage. Le dispositif de communication de données (2) convertit les données et le dispositif de communication de données (2) transmet les données converties sur une liaison de données vers l'appareil mobile (8). Le procédé selon l'invention est caractérisé en ce que, dans la transmission de données entre le dispositif de communication de données (2) et l'appareil mobile (8), on utilise un deuxième protocole de données dans lequel il n'y a pas d'arbitrage. L'invention concerne en outre un dispositif de communication de données (2) grâce auquel le procédé selon l'invention peut être mis en œuvre.
