Concept for implementation-independent communication interface for Scania's System architecture for autonomous vehicles

Abstract

Driver less vehicles has risen as another field of innovation and enthusiasm for late years. The major vehicle producers are attempting to execute the innovations required for autonomous vehicles which in turn increases the number of application also. All these new applications includes a communication of a larger amount of data which has prompted an activity of implementing ethernet to automotive industry and the idea is being assessed. It is important to explore the present circumstance of the com-munication structure and topologies present in vehicles today.The primary objective of this thesis was to investigate how interface description language of current commercial solutions like protobuf, thrift, avro etc. can be adaptedto automotive.A literature study was conducted on different IDL’s and the current Scania’s system architecture.The study included an analysis on the expressiveness of the description languages and how it can be mapped on to the existing automotive systems. This study also involved different protocols capability in terms of getting defined without knowing the hardware interfaces. To demonstrate the feasability in using commercialIDLs in the automotive industry, a small scale demo was implemented using protobuf .The study results indicated how to define an IDL for system architecture in au-tomotive industry and also the possibility of communication between heterogeneous systems with the IDL concept
