Abstract

A method and a device is provided to allow additional data to be transmitted between at least two users of a bus system. The transmitted data frames have a logic structure according to the CAN standard ISO 11898-1, and at least two additional short bits are inserted within a temporal bit length of at least some of the CAN bits such that at least for one of the two possible values of the current CAN bit, the first one of the additional bits inserted into this CAN bit is transmitted using a bus level that is the opposite of this value.
