The disclosure relates to a method for serially transmitting a frame from a transmitter to at least one receiver via a bus line, as well as a subscriber station for a bus system. According to said method, stuff bits for generating additional signal edges are inserted into the frame by the transmitter according to a predetermined rule, and the stuff bits are removed again by the receiver when evaluating a received frame, a CRC calculation logic of a CRC generator calculating a CRC checksum that is comprised by said frame, and a value of “1” being inserted into said CRC calculation logic in an additional evaluation step if a value of “0 . . . 0” has been determined for the CRC checksum in the running calculation executed by the CRC calculation logic.

A user station for a serial bus system and a method for transmitting a message in a serial bus system. The user station includes a communication control device for transmitting messages to a bus of the bus system and/or for receiving messages from the bus of the bus system, and a bit rate switchover unit for switching over a bit rate of the messages from a first bit rate in a first communication phase to a second bit rate for a second communication phase. The bit rate switching unit is designed to switch the bit rate from the first bit rate over to the second bit rate, due to an edge of a predetermined bit sequence that includes one bit of the first communication phase and one bit of the second communication phase.

A user station is described. The user station includes a communication control device for transmitting and/or receiving messages to/from a bus of a serial bus system, a format switchover checking unit for checking whether the communication control devices of the bus system have switched over the format of the messages from a first format in a first communication phase to a second format for a second communication phase, and a transceiver device which, for transmitting in the first format, generates a first bus state for a first digital data state of the messages and a second bus state for the second digital data state of the messages so that the second bus state can overwrite the first bus state. The transceiver device, for transmitting in the second format, generates different bus states so that the bus states for the different digital data states of the messages cannot overwrite one another.
