Abstract: A method is provided for monitoring a quiescent state in a motor vehicle. In accordance with the method, a wake-up controller (10) of a control device selects at least one peripheral component from among a plurality of peripheral components of the motor vehicle. The peripheral components are connected to the control device in an event-controlled manner in the quiescent state. The wake-up controller (10) checks an operating state of the selected peripheral component and wakes up the motor vehicle from the quiescent state depending on the operating state.
