Verfahren zum ueberwachen eines datenverkehrs zwischen steuergeraeten eines kraftfahrzeugs sowie entsprechend ausgestattetes kraftfahrzeug

The invention relates to a method for monitoring data traffic between control devices (12, 13) of a motor vehicle (10), wherein at least one data pattern (23) of a packet type to be monitored and/or detected and/or data content is stored in a content addressable memory (22) such that by means of the content addressable memory (22), an assigned hit signal (27) is generated in response to input data (25) which contains the relevant data pattern (23), and a network processor (21) reads detection data (31) from received data packages (18) at predetermined monitoring positions (31) and therefrom forms input data (25) for the content addressable memory (22) and by inputting the input data (25) into the content addressable memory (22), checks whether a hit signal (27) is produced, and a microprocessor (29) detects, by means of a predetermined comparison routine (32) and on the basis of transmission plan data (33) which describe a correct transmission scheme of the control devices (12, 13), whether the hit signals (2
