Method for Serially Transmitting a Frame from a Transmitter to at Least One Receiver via a Bus System, and a Subscriber Station for a Bus System

A subscriber station for a bus system, the subscriber station comprising:

• a transmitting/receiving device configured to at least one of (i) transmit a frame to and (ii) receive the frame from a further subscriber station of the bus system via a bus line;
• and
• a verifying device configured to verify a CRC checksum of the frame, which is calculated by a CRC calculation logic of a CRC generator,
• wherein the transmitting/receiving device is configured to at least one of (i) before transmitting the frame, insert stuff bits into the frame according to a predetermined rule to generate additional signal edges, and (ii) remove the stuff bits from the frame when evaluating the received frame,
• wherein the verifying device is configured to insert a value “1” into the CRC calculation logic in an additional evaluation step in response to a value of “0 . . . 0” being found for the CRC checksum in the calculating carried out by the CRC calculation logic.

A bus system comprising:

• a bus line;
• and
• at least two subscriber stations configured to be connected to one another via the bus line such that they can communicate with one another, at least one of the at least two subscriber stations comprising:
• a transmitting/receiving device configured to at least one of (i) transmit a frame to and (ii) receive the a frame from a further subscriber station of the at least two subscriber stations via the bus line;
• and
• a verifying device configured to verify a CRC checksum of the frame, which is calculated by a CRC calculation logic of a CRC generator,
• wherein the transmitting/receiving device is configured to at least one of (i) before transmitting the frame, insert stuff bits into the transmitted frame according to a predetermined rule to generate additional signal edges, and (ii) remove the stuff bits from the frame when evaluating the received frame,
• wherein the verifying device is configured to insert a value “1” into the CRC calculation logic in an additional evaluation step in response to a value of “0 . . . 0” being found for the CRC checksum in the calculating carried out by the CRC calculation logic.
