Sensor interface that provides a long CRC to improve the functional safety

A data transmission system, comprising an automotive sensor network system (ASNS), which is connected to a plurality of source locations over a common bus, wherein the ASNS is adapted to determine the source from which the data frame and the first Einheitsprufsumme are received, and based on the detection of the source to apply appropriate decoding method to calculate the ASNS-local Datenrahmenprufsummen and ASNS-local Einheitsprufsummen. A higher-order redundancy check is made over a sequence of data frames to detect errors in the reception, caused by temporary strong interference that may be present in the transmission path.
