Advanced control units´ diagnostic based on Ethernet for smart cars

Numerous electronic systems have been added to the vehicle to provide more comfort and safety to the drivers. This has led to a rise in the number of ECUs (Electronic Control Units) and consequently an eminence in the number of connections and networks as well as the amount of transmitted information. With these innovations and advances in technology and their high requirements, Ethernet is introduced to the automotive industry to profit from its benefits. Among the applications that this protocol has occupied we found the analysis and diagnosis of network traffic flowing between the ECU of the car. To successfully analyze all the exchanged data between the ECUs, an efficient analysis system is required. Indeed, this system should optimally capture all Ethernet packets without any loss allowing the realization of filters, obtaining statistics and real-time display.
