Preliminary Work on Automatic ARXML Generation for SOME/IP in AUTOSAR Classic Platform

초록

The vehicle electrification trend has led the number of ECUs in automotive up to 100. Inefficient network architecture from a large number of ECUs and the need for high bandwidth caused automotive Ethernet to be adopted in the automobile industry. Messages can be sent with the support of Ethernet-based SOME/IP protocol on the AUTOSAR Platform. We examined the structures of the SOME/IP message format and AUTOSAR communication stack. We also showed what AUTOSAR communication modules to configure and how messages can be filled with SOME/IP header and payload by simply writing out FIDLs. The process of automatic ARXML generation consists of 1) importing each of the ARXML files from modules related to the Ethernet communication stack, 2) Automatically modifying ARXML files from FIDL files, 3) Updating all the ARXML files that is imported before. By this method, users do not have to manage settings belonging to Ethernet.
