In order to develop the bottom driver software more rapidly and efficiently which are used in automotive battery management system and to get rid of high dependence on the hardware and low reusability of the drivers in automobile controller, this paper puts forward a kind of driver design method based on automotive open system architecture (AUTOSAR). Simulation modeling module has been made with the...
Modern systems are becoming ever more complex and, thus, the possibility of failures in their operation is also growing. The complexity makes it practically impossible to make the hardware and software error-free without the special effort invested in the design process. Recently, a design methodology with the objective to avoid unacceptable risk of physical injury or of damage to the health of people,...
The vehicles typically have a lifetime of several years, possibly even longer than 10 years, over which communication technology will almost certainly evolve dramatically. The challenge of automotive communication platform is to ensure that a radio communication component remains relevant over the entire lifetime of a vehicle. A highly efficient software reconfiguration solution is introduced in this...
In this paper, we propose and implement two electronic control unit (ECU) architectures for real-time automotive cyber-physical systems that incorporate security and dependability primitives with low resources and energy overhead. These ECUs architectures follow the multiprocessor system-on-chip (MPSoC) design paradigm wherein the ECUs have multiple heterogeneous processing engines with specific functionalities...
The increasing demand of new functionalities in next generation vehicles, leads to a growth of the complexity level for the E/E automotive systems. On the same way, the automotive software also tends to follow the same pace, so new methods should be adopted to deal with this scenario of complexity. The next generation of automotive embedded software is rapidly migrating to the AUTOSAR standard, which...
The automotive industry is one of the most diversified, complex and important area into research and development software engineering solutions. Multimedia and infotainment systems, from nowadays cars, require more and more software and hardware resources which bring about the adaptation of the existing communication and diagnosis standards. The market wishes are moving towards wireless, affordable...
Measurement-Based Probabilistic Timing Analysis (MBPTA) derives WCET estimates for tasks running on processors comprising high-performance features such as caches. MBPTA's correct application requires the system to exhibit certain timing properties, which can be achieved by injecting randomisation in the timing behaviour of the task under analysis. However, existing software-randomisation techniques...
Current trend is to increase the overall use of electronic systems in daily life. Exemplarily, the complexity of automotive electronic control unit (ECU) systems is rising due to the number of components involved and the tighter interactions between these heterogeneous components (analog, digital hardware, or software), resulting in a more and more challenging verification. In this paper, we show...
The increasing complexity of automotive networks has led to broad security issues related to human safety. On the other hand, to solve problems of network overload, the automotive world is moving in the direction of using an Ethernet backbone for in-vehicle communications. Therefore, the security of Ethernet protocols for such applications has become a significant concern. The IEEE 802.1X-2010 standard...
Embedded systems are becoming ubiquitous and are subject to demanding standards in both safety and reliability. Modern vehicles, which must respect ISO 26262 standards, use up to 100 Electronic Control Unit (ECUs). Advances in microelectronics enable integration of more functions in the ECU, but at the cost of greater unreliability in hostile operating environments, such as electromagnetic fields,...
The requirements, functionality, and consequently also the complexity of software used in the automotive industry has continuously been increasing over the last decades. To cope with this development, main car manufacturing companies and automotive suppliers established the AUTOSAR partnership back in 2003. Its main objective is to reduce development costs and to enhance cooperation between different...
This paper presents hardware platform for automotive camera based on Ethernet AVB (Audio/Video Bridging) for application of ADAS (Advanced Driver Assist System), infotainment and multimedia in an in-vehicle network. The hard platform supports not only various camera sensors, but also standard Ethernet PHY (Physical Layer) and BroadR-Reach for the two-wire UTP (Unshielded Twisted Pair) cables of 100...
The standard solution for automotive control networks is the Control Area Network (CAN) bus. Almost any vehicular computer system comprehends at least one CAN line. For the past two decades, software development for control system has been strongly connected to the properties and interfaces of the CAN bus. Currently, the automotive industry is in the middle of a technology leap towards an information-based...
Performance demand of Critical Real-Time Embedded (CRTE) systems implementing safety-related system features grows at an exponential rate. Only modern semiconductor technologies can satisfy CRTE systems performance needs efficiently. However, those technologies lead to high failure rates, thus lowering survivability of chips to unacceptable levels for CRTE systems. This paper presents SESACS architecture...
Design failure mode and effects analysis (DFMEA) is part of any Design for Reliability (DfR) effort to design, develop, and build a large, technologically-challenging product. As there may be many cross-functional teams working on DFMEA at any point in time, management must provide effective oversight and project management skills to ensure that the final product will not only be on time, but also...
Electronic control units and on-board networks for automotive applications cover a big variety of functions that in many cases are responsible of safety critical behavior of the vehicle. Safety needs and goals claim that the software involved in such functions be designed by adopting opportune methods and practices. The paper presents a survey on most of these practices in the light of emerging standards.
