Claim:
1. A method for serially transmitting data in a bus system having at least two bus users, which exchange data frames over the bus, the bus users deciding which data frames they receive, as a function of an identifier, the method comprising: reducing a temporal bit length in at least one second, specified or specifiable region in comparison with the first region; and signaling a change in the temporal bit length by the sender, using an identification contained in the same or one of the preceding data frames; wherein the data frames have a logic structure according to CAN standard ISO 11898-1, wherein the temporal bit length inside of a data frame is at least one of two different values, the temporal bit length for at least one first, specified or specifiable region within the data frame meeting the requirements of the CAN standard ISO 11898-1, and wherein for a limited period of time after an arbitration has occurred, a temporal duration of the bits, within a data frame, is reduced in comparison with a value used for the arbitration; wherein the identification is sent in a preceding data frame, and using the identification, at least one bus user is informed that a subsequent data frame sent to it will have a reduced bit length.
