Abstract
A method and a bus connection unit for selectively waking participants of a bus system in an idle state, the participants not in the idle state exchanging messages via the bus using a serial communication protocol, the messages characterized by a leading identifier, the participants not in the idle state deciding based on the identifier whether they receive the message, the messages being evaluated by the participants in the idle state in at least three phases, a number of signal properties, edges and/or edge changes being determined in a first phase, a sequence of time intervals between signal properties, edges and/or edge changes being determined in a second phase, a wake pattern being determined from the serial signal sequence of the message in a third phase, and participants in the idle state leaving the idle state as a function of the items of information determined during the three phases.
