| 摘要 |
The invention relates to a method for serial data transmission in a bus system with at least two participating data processing units, the data processing units exchanging messages via the bus, wherein the transmitted messages have a logic structure according to CAN Standard ISO 11898-1. In the event of a first switching condition, the data field of the messages can comprise, in a deviation from CAN Standard ISO 11898-1, more than 8 bytes, wherein the values of the Data Length Code are interpreted at least partially in deviation from CAN Standard ISO 11898-1 for determining the size of the data field in the event of the first switching condition. At least one buffer memory is provided for transmitting data between the data field and the application software, and the transmitted quantity of data is at least adapted in accordance with the size difference between data field and used buffer memory when the size of the data field differs from that of the used buffer memory. |
