Implementation of AUTOSAR Communication Stack Modules

The following paper is the result of a six-month project at the Belgian company Multronic s.r.l in Carmagnola (TO); it designs, manufactures and supplies diesel engine emission aftertreatment systems. The objective of the thesis activity is to implement a communication network with the main reference to the basic elements of AUTOSAR architecture and features. The idea is to have a code independent of the hardware, easy to reuse and with a good level of abstraction. This paper shows the implementation of a firmware that can meet the need to have a code as modular as possible, satisfying the functional requirements in a single platform. The project was characterized by a training phase through the study of the most commonly used automotive communication protocols and by an analysis of the characteristics of the fundamental standards. In particular, the focus is on development of the Serial Network and CAN network. The fundamental points of the project are followed gradually: in primis there is a brief introduction that anticipates the characteristics of the developed SW, the main aspects of the testing phase and the requirements in terms of quality. Afterwards, there is a presentation of the technical features of the HW used, followed by chapters that show the topics studied to be able to address this thesis activity. The Chapters 5 and 6 represent the core of the project: the SW is described with its main characteristics and test activity. The paper ends with a conclusive analysis of the activity proposing possible future developments.
