METHOD AND DEVICE FOR TRANSMITTING DATA HAVING VARIABLE BIT LENGTH

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 data frames having a logic structure according to the CAN standard, ISO 11898-1,...

More Information
Summary: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 data frames having a logic structure according to the CAN standard, ISO 11898-1, the temporal bit length (L1, L2) inside of a data frame being able to assume at least two different values, the temporal bit length (L1) for at least one first, specified or specifiable region within the data frame meeting the requirements of the CAN standard, ISO 11898-1, the temporal bit length (L2) in at least one second, specified or specifiable region being reduced in comparison with the first region, and a change in the temporal bit length being signaled by the sender, using an identification (310) contained in the same or one of the preceding data frames.
