Abstract

A method is provided for operating a bus system in particular of a motor vehicle, in which messages of the bus system are received, and as a function of these messages, it is detected whether a party of the bus system sending these messages is a party logging on to the bus system.

First claim

What is claimed is:

1. A method for operating a bus system of a motor vehicle, the method comprising:
receiving messages of the bus system;
detecting whether a party of the bus system sending the messages is a party logging on to the bus system; and
initiating measures to deactivate the sending party as a function of the result of the detection.

2. The method as recited in claim 1 , further comprising:
detecting whether the sending party is a new party of the bus system as a function of the messages.

3. The method as recited in claim 1 , wherein the measures include deactivating a power supply of the sending party.

4. The method as recited in claim 1 , wherein the measures include sending self-deactivation messages to the sending party which prompt the sending party to at least partially deactivate itself.

5. The method as recited in claim 4 , wherein the self-deactivation messages include messages which transmit a piece of information to the sending party that the motor vehicle is assuming a predefinable state.

6. The method as recited in claim 4 , wherein the self-deactivation messages include messages which transmit a piece of information to the sending party that at least one of: (i) a query of certain data of parties of the bus system is not supported, and (ii) the query by the sending party is invalid.

7. A method for operating a bus system of a motor vehicle, the method comprising:
receiving messages of the bus system;
detecting whether a party of the bus system sending the messages is a party logging on to the bus system;
detecting whether the sending party has carried out a data query, and suppressing a correct response to the data query based on the detecting.

8. The method as recited in claim 7 , wherein the suppression includes transmitting at least one message to the sending party.

9. The method as recited in claim 8 , wherein content of the transmitted message is designed as if it were a response to the data query by a detected addressee of the transmitted message.

10. The method as recited in claim 9 , wherein the transmitted message includes an incorrect response to the data query.

11. The method as recited in claim 7 , wherein the suppression includes preventing an actual response by the detected addressee.

12. A non-transitory machine-readable storage medium on which is stored a computer program for operating a bus system of a motor vehicle, the computer program, when executed by a computer, causing the computer to perform:
receiving messages of the bus system;
detecting whether a party of the bus system sending the messages is a party logging on to the bus system; and
initiating measures to deactivate the sending party as a function of the result of the detection.

13. A control and/or regulating device configured to operate a bus system of a motor vehicle, the control and/or regulating device configured to:
receive messages of the bus system;
detect whether a party of the bus system sending the messages is a party logging on to the bus system; and
initiating measures to deactivate the sending party as a function of the result of the detection.

14. A control and/or regulating device configured to operate a bus system of a motor vehicle, the control and/or regulating device configured to:
receive messages of the bus system;
detect whether a party of the bus system sending the messages is a party logging on to the bus system;
detect whether the sending party has carried out a data query, and suppress a correct response to the data query based on the detecting.

15. A non-transitory machine-readable storage medium on which is stored a computer program for operating a bus system of a motor vehicle, the computer program, when executed by a computer, causing the computer to perform:
receiving messages of the bus system;
detecting whether a party of the bus system sending the messages is a party logging on to the bus system;
detecting whether the sending party has carried out a data query, and suppressing a correct response to the data query based on the detecting.
