Abstract

A method for the switching of participants of a bus system from a first state with reduced energy consumption to a second state with increased energy consumption relative to the first state, wherein, for communication between the participants of the bus system, data frames are transmitted which comprise, inter alia, a message identification field (e.g. CAN message) and a useful-data field (e.g. CAN payload), wherein, according to said method, each participant, for switching from the first state to the second state, reacts on data frames with respectively predetermined data contents in the message identification field as well as in the useful-data field. Further, in the bus system, for selective switching of a participant from the first state to the second state, those data frames will be transmitted on whose message-identification-field contents and useful data-field-contents the selectively addressable participant reacts.
