Automotive software

Abstract: The amount of software in cars grows exponentially. Driving forces of this development are the availability of cheaper and more powerful hardware, as well as the demand for innovation through new functionality. The rapidly growing significance of software and software-based functionality is at the root of various challenges in the automotive industries. These concern their organization, definition of key competencies, processes, methods, tools, models, product structures, division of labor, logistics, maintenance, and long-term strategies. This paper pinpoints the idiosyncrasies of the domain, characterizes the essentials of automotive software, and discusses the challenges of automotive software engineering

Abstract: Cost pressure, flexibility, extensibility and the need for coping with increased functional complexity are changing the fundamental paradigms for the definition of automotive and aeronautics architectures Traditional designs are based on the concept of a Federated Architecture in which integrated hardware/software components [Electronic Control Units (ECUs)] realize mostly independent or loosely interconnected functions These components are connected by bus and cooperate by exchanging messages This paradigm is now being replaced by the Integrated Architecture, - the concept comes from Integrated Modular Avionics (IMA) introduced by the avionics community (see C B Watkins and R Walter, ?Transitioning from federated avionics architectures to integrated modular avionics?, in Proc 26th Digital Avionics Syst Conf, Oct 2007) but it is certainly general and applicable to other fields and in particular, automotive - in which software components can be supplied from multiple sources, integrated on the same hardware platform or physically distributed and possibly moved from one CPU to another without loss of functional and time correctness and providing a guaranteed level of reliability This shift will decouple software design from the hardware platform design and provide opportunities for the optimization of the architecture configuration, increased extensibility, flexibility and modularity However, the integration of software components in a distributed system realizing a complex functional behavior and characterized by safety, time and reliability constraints requires a much tighter control on the component model and its semantics, new methods and tools for analyzing the results of the composition, whether by simulation or formal methods, and methods for exploring the architecture solution space and optimizing the configuration We provide a general overview of existing challenges and possible solutions to the design and analysis problem, with special focus on the automotive domain The development of such methods and tools must necessarily consider compatibility with existing modeling languages and standards, including UML, AUTOSAR and synchronous reactive models, on which the widely used commercial products Simulink and SCADE are based

Abstract: Modern cars consist of a number of complex embedded and networked systems with steadily increasing requirements in terms of processing and communication resources. Novel automotive applications, such as automated driving, rise new needs and novel design challenges that cover a broad range of hardware/software engineering aspects. In this context, this paper provides an overview of the current technological challenges in on-board and networked automotive systems. This paper encompasses both the state-of-the-art design strategies and the upcoming hardware/software solutions for the next generation of automotive systems, with a special focus on embedded and networked technologies. In particular, this paper surveys current solutions and future trends on models and languages for automotive software development, on-board computational platforms, in-car network architectures and communication protocols, and novel design strategies for cybersecurity and functional safety.
