Connected In-Car Multimedia: Qualities Affecting Composability of Dynamic Functionality |
In-Car Multimedia systems have become a fundamental part of a car's human-machine interface. Recent developments within the domain of mobile consumer electronics create demands for flexible functionality by use of after-market applications, also within the automotive sector. Further, current systems already provide connectivity to enable dynamic data using cellular access networks. Future systems will provide comparable features not only for data, but also for functionality. The capabilities for modification or enhancement of functionality using network connectivity requires a thorough consideration of certain software qualities, also with respect to operation within a safety critical environment and provisioning of an adequate user experience. This paper characterises relevant software qualities with a strong focus on composability. The objective is to provide a base for building a modular system that appears as a homogenous whole, while providing sufficient dependability. An architecture is proposed to illustrate the applicability of those qualities to a particular software system.
