Evaluation and integration of DDS middleware for interconnection between Android Automotive and AUTOSAR

Abstract

Modern day vehicles are transforming into software-defined vehicles, where the functions and features are primarily enabled through software services. The increasing addition of functionalities has led to a rise in system complexity. The automotive system consists of different domains and components, developed simultaneously by different vendors, each serving different purposes and complying with different requirements and technologies. It is essential to establish effective interconnection between these domains for enhanced feature diversity and overall system performance. Advanced Driver Assistance Systems (ADAS) and In-Vehicle Infotainment (IVI) are the two major domains that are rapidly expanding and driven by increasing customer demands. Android Automotive has established itself as a major player in the car IVI landscape due to its extensive features and intuitive user interface. The difference in standards used by the two domains, i.e AUTomotive Open System ARchitecture (AUTOSAR) in ADAS and Android Automotive in IVI, leads to the necessity of a common interface and communication protocol which is supported by both domains. This thesis presents the solution for intercommunication between AUTOSAR and Android platforms using Data Distribution Service (DDS) middleware. Additionally, the various features and service-oriented communication patterns offered by DDS in automotive applications are discussed along with its distinctive features compared to current protocol such as Scalable Service-Oriented MiddlewarE over IP (SOME/IP). The identification of key components and integration of DDS middleware approaches are central aspects of this thesis. As a proof of concept, the design was implemented with minor modifications, and successfully demonstrated on a hardware setup, exhibiting inter-domain communication using DDS middleware.
