Abstract
A method for data communication in a vehicle between an in-vehicle device and a mobile device coupled with the vehicle includes transmitting, by the in-vehicle device, data via a data bus of the vehicle to an in-vehicle data communication device, a first data protocol being used for this purpose, in which an arbitration occurs. The data communication device converts the data, and the data communication device transmits the converted data via a data link to the mobile device. A second data protocol is used in the data transmission from the in-vehicle data communication device to the mobile device, in which no arbitration occurs. A data communication device by which the method of the invention may be implemented is also described.

19. A data communication device in a vehicle for data communication between an in-vehicle device and a mobile device coupled with the vehicle, comprising:
-
a first interface adapted for receiving data from the in-vehicle device via a data bus of the vehicle, a first data protocol being used in which an arbitration occurs, a converter adapted for converting the received data, and a second interface adapted for transmitting the converted data via a data link to the mobile device, wherein the converter is adapted to convert the data for the data transmission to the mobile device into a second data protocol, in which no arbitration occurs. - View Dependent Claims (20)
