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.

12. The communications system as claimed in claim 11, wherein by way of the bus system a bus protocol is transmitted which is composed essentially of an interface protocol of the interface and data which are specific to the bus system.

13. The communications system as claimed in claim 12, wherein by way of the bus system a bus protocol is transmitted which is composed of an interface protocol of the interface and prefixed data which are specific to the bus system.

14. The communications system as claimed in claim 12, wherein the interface protocol comprises an operation field for identification of a task to be performed by means of the information relating to operation of the vehicle.

15. The communications system as claimed in claim 12, wherein the interface protocol comprises a data field with a value for the information relating to operation of the vehicle.

16. The communications system as claimed in claim 12, wherein the interface protocol comprises an ID field for identification of the information relating to operation of the vehicle.

17. The communications system as claimed in claim 14, wherein the interface protocol comprises at most the operation field, the data field and the ID field.

18. The communications system as claimed in claim 14, wherein the operation field comprises information which indicates whether the protocol relates to a message to be sent or a received message.

19. The communications system as claimed in claim 14, wherein the interface protocol comprises an information field for identifying a message to be sent or a received message.
