Abstract
The invention relates to a communication system for a motor vehicle for transmitting an information relating to the operation of the motor vehicle from a transmitting control device to a receiving control device. The communication system comprises an interface for the input or output of the information relating to the operation of the motor vehicle. Communication can be established via the interface by means of a protocol which comprises an operation field for identifying a task to be carried out using the information relating to the operation of the motor vehicle.

32. A method of transmitting information in a motor vehicle through a communication system, the method comprising:
- transmitting the information from a sending control device;
receiving the transmitted information in a receiving control device;
wherein;
the information is inputted into and/or outputted by the communication system through an interface by operating a protocol; andthe protocol comprises identifying an operation field, the operation field corresponding to a task to be performed in response to the information, identifying a data field with a value corresponding to the operation field, and identifying an ID field comprising a first region designating a logic control device to which the information relating to operation of the motor vehicle is assigned, and a second region identifying the information relating to operation of the motor vehicle, and wherein the information is transmitted when a predetermined repetition time has passed since the last transmission, and the predetermined repetition time is different for different information relating to the operation of the vehicle. - View Dependent Claims (33, 34, 35, 36)
