Automotive Ethernet Architecture for the Connected Dacia Logan Electric Vehicle

Abstract

Automotive Ethernet is an ideal choice for high-speed buses within modern vehicles, used by Advanced Driver Assistance Systems (ADAS), multimedia, navigation, telematics. This paper analysis the advantages of using Automotive Ethernet in vehicles. For a Dacia Logan Electric Vehicle (EV), converted from a classical vehicle with Internal Combustion Engine (ICE), an Ethernet network architecture is proposed for the communication between different Electronic Control Units (ECUs). To gather data from the vehicle's Controller Area Network (CAN), a CAN to Ethernet gateway is developed based on Raspberry Pi. To send data to a web server, an industrial Teltonika RUTX09 mobile router with Ethernet interface is used. Different measurements are performed for acquiring data from the CAN bus, or to investigate the network performances of the mobile Internet Service Provider (ISP). Finally, signal integrity of Ethernet bus is measured and analyzed.
