摘要： In a bus system that includes at least two subscribed data processing units that exchange messages via a bus in a serial data transmission, the transmitted messages are of a logical structure that includes a start-of-frame bit, an arbitration field, a control field, a data field, a CRC field, an acknowledge field and an end-of-frame sequence, the control field including a data length code, which contains information regarding the length of the data field. The messages are constructed such that the data field of the messages can include more than eight bytes, and, in a method of such serial data transmission, the values of the data length code are interpreted at least partially in a manner that deviates from the CAN standard ISO 11898-1 for determining the size of the data field.

The device includes (a) an arrangement setting a dominant bus level in the form of a first voltage difference between the two bus lines by driving a first electric current, and the device is suitable for the recessive bus level to set in as the second voltage difference between the two bus lines, at least partially by the flowing of a discharge current via terminating resistors connected to the bus lines; and (b) an arrangement to speed up the setting of at least one of the bus levels by driving at least one additional electric current, at least in response to the presence of a switching condition.

摘要： A method for serial data transfer in a bus system having at least two bus subscribers that exchange messages via the bus, the transmitted messages having a logical structure according to CAN standard ISO 11898-1, the logical structure encompassing a start-of-frame bit, arbitration field, control field, data field, CRC field, acknowledge field, and end-of-frame sequence, the control field encompassing a data length code having an information item regarding the data field length. When a first marker (EDL) is present, the control field of the messages, divergently from the CAN standard ISO 11898-1, encompasses more than six bits; when the first marker (EDL) is present, the control field of the message is expanded to include at least one further bit (ESI); and the further bit (ESI) or one of the further bits causes an information item regarding the “error passive” state of the bus subscriber to be integrated into transmitted messages.
