SUBSCRIBER STATION FOR A SERIAL BUS SYSTEM AND METHOD FOR COMMUNICATION IN A SERIAL BUS SYSTEM

A user station for a serial bus system. The user station includes a communication control device for controlling a communication of the user station with at least one other user station, and a transceiver device for transmitting a transmission signal, generated by the communication control device, onto a bus, so that for a message that is exchanged between user stations of the bus system, the bit time of a signal transmitted onto the bus in the first communication phase is different from a bit time of a signal transmitted in the second communication phase. The communication control device generates the transmission signal according to a frame in which a field for a header check sum and a field for a frame check sum are provided, and computers the header check sum from all bits in the header of a frame that is formed for the message, except fixed stuff bits.
