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.
