Abstract

In a method for enabling transmission of larger data quantities relatively rapidly in a data network, the sent data frames have a logical structure according to CAN Specification ISO 11898-1, the bit length in time within a data frame being able to assume at least two different values; for a first specifiable range within the data frame, the bit length in time being greater than, or equal to a specified minimum value of approximately one microsecond and in at least one second specifiable range within the data frame the bit length in time compared to the first range is at least halved, preferably less than halved; the change of the bit length in time being implemented by using at least two different scaling factors for setting the bus time unit relative to a shortest time unit or the oscillator clock pulse during running operation.
