Method and apparatus for improving data transmission reliability in serial data transmission with flexible message size

摘要

A method for serial data transmission in a bus system with at least two bus subscribers exchanging messages over a bus, wherein the right to send to the bus for each message destined for the bus subscriber is Which result of the CRC calculation initiated in parallel and in accordance with the appropriate indication (EDL) given by the arbitration method according to the CAN standard ISO11898-1 is used to check the correct data transmission Is determined, and for at least one value of the indicator, an additional condition is checked, and when such an additional condition exists, the sender fixes at least part of the message with one or more bits. The above method is described wherein a stuff bit sequence is inserted into a message. [Selection] Figure 4
