1. A control device for a vehicle network that includes at least one bus system, the control device comprising:
- a microprocessor;
a transceiver; and
a module that detects network messages that include vehicle velocity data, the network messages being transmitted on at least one bus system, the module controlling at least one of switching on or off of a sleep mode for the control device based on content of the detected network messages,wherein the content indicates a previously defined state or event during the operation of the motor vehicle,wherein the control device is switched off or into a sleep mode based on detection of the previously defined state or event during the operation of the motor vehicle, andwherein the previously defined state is the vehicle velocity V, wherein if V>
Vlimit, the control device is switched off or switched into the sleep modewherein the module comprises at least one counter (C), wherein an operating mode is switched over if the counter (C) reaches a predetermined value.

Abstract
A control device for a vehicle network, having a microprocessor and a transceiver. The control device can be switched off or switched to a sleep mode during a previously defined state or event during the operation of the motor vehicle and/or the control device can be awakened from the sleep mode during a previously defined state or event during the operation. The disclosed embodiments also relate to a method for operating a vehicle network.

11. A method for operating a vehicle network that includes at least one bus system that includes a plurality of control devices, each control device comprising a microprocessor, and a transceiver, the method comprising:
-
detecting a network message including vehicle velocity data, the network message being transmitted on the at least one bus system using a network message detection module; controlling at least one of switching on or off of a sleep mode for at least one control device of the plurality of control devices based on content of the detected network messages that indicates a previously defined state or event during motor vehicle operation; and switching off the at least one control device or switching the at least one control device into a sleep mode based on detection of the previously defined state or event during operation of the motor vehicle, wherein the previously defined state is the vehicle velocity V, wherein if V>
Vlimit, at least one control device is switched off or switched into the sleep mode,wherein an operating mode is switched over if a counter (C) reaches a predetermined value. - View Dependent Claims (12, 14)

15. A control device for a vehicle network of a motor vehicle, the vehicle network including at least one bus system, the control device comprising:
-
a microprocessor; a transceiver; and a module that detects transmitted network messages that include vehicle velocity data, the network messages being transmitted on the at least one bus system, wherein the control device is switched on or off of a sleep mode based on content of a detected network messages, wherein the content of the detected network message indicates a previously defined state or event during the operation of the motor vehicle, wherein the control device is switched off or into a sleep mode in response to detection of a specific previously defined state or event during the operation of the motor vehicle, wherein the control device is switched off or into the sleep mode if; the previously defined state is the motor vehicle velocity and the detected velocity is greater than a specified velocity limit, wherein the module comprises at least one counter (C), wherein an operating mode is switched over if the counter (C) reaches a predetermined value.
