Market readiness of on-board automotive software-intensive systems is tightly linked to the availability of appropriate certification schemes aimed at keeping the car makers confident and the consumers safe - especially in the context of Autonomous Driving, which is the next frontier of the automotive industry. Advanced driver assistance systems (ADAS) are going to be pervasively used in modern automobiles...
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,...
Automotive electronic control units (ECUs) have been the focus of many security researchers who have demonstrated the ability to affect the deterministic operation of safety critical vehicle cyber physical systems. Flaws in software design that have direct impacts to the functional safety of a target vehicle have been discovered. The rapid increase in data connectivity within a modern automobile has...
Process of detailed testing and verification of all automotive embedded software components generates detailed reports about each segment of tested electronic control units (ECU). The very first group of tests in this process is Acceptance tests, and one of the most important tests in this stage of testing and verification is interface check of the software component. The interface check must ensure...
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...
Modern automotive systems consist of hundreds of functionalities implemented in software. Moreover, these functionalities are constantly evolving with increasing demand for automation, industry competition and changing sensor and actuator capabilities. Correspondingly, it is important to adapt the engineering and software development processes for such systems to consider fast management of this evolution...
Systems of Systems are defined as a collection of component systems that produce results not achievable by the individual systems alone. SoS serves to distinguish true multi-domain and multi-discipline systems from others who have taken up the systems mantle, most noticeably software and IT spaces. But SoS is more than just a higher level focus on configuration management (CM), requirements management...
The market opportunity for driver assisted, driver piloted, and fully driverless cars is projected to reach 42 Billion by 2025. As a result, advanced “IMA like” automotive solutions are being explored and are focused on developing and maturing next generation transformational IMA technologies. Five future IMA dual use focus areas that have the potential to be transformational enablers for affordability,...
New applications like highly automated driving, Car-2-X, software updates over the air, or vehicles as part of the internet of things raise completely new requirements to a software platform for the next generation of ECUs. AUTOSAR as the worldwide leading standardization organization for in-vehicle software bears this challenge and paves the way making vehicles intelligent and adaptive. Based on...
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...
Software Development for Automotive Systems is becoming more and more complex. Cars are turned into software intensive and to some extent software defined products by the increasing functionality of the various electronic control units (ECUs). Major driving factors for this development are complex human-machine-interfaces (HMI), eMobility and autonomous driving. Consequently, developing the software...
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...
Automotive original equipment manufacturers (OEMs) and suppliers of electrical and electronic subsystems are required to perform bench level electrical and electromagnetic compatibility (EMC) validation testing. This is an important process that requires a significant investment in time and money. In an effort to improve the efficiency of testing, a survey was developed to gain an understanding of...
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...
This paper presents performance analysis of Controller Area Network with Flexible Data-Rate (CAN FD), a new automotive communication protocol that was officially proposed by Robert Bosch GmbH in March 2012, with consideration of the size of data field of the CAN FD message. Using the CANoe simulation tool by Vector GmbH, we measured the performance of CAN FD for ECU (Electronic Control Unit) re-programming,...
MC/DC (modified condition/decision coverage) is a structural code coverage metric, originally defined in the standard DO-178B [1], intended to be an efficient coverage metric for the evaluation of the testing process of software incorporating decisions with complex Boolean expressions. The upcoming standard ISO 26262 [2] for safety-relevant automotive systems prescribes MC/DC for ASIL D as a highly...
The automotive industry is concerned with developing large and complex embedded systems. The original equipment manufacturers (OEMs) are responsible for the safety of their systems, enforced by law in terms of liability. At the same time, there is a number of laws, for example the Automobile Safety Act, that has to be obeyed by the specification. We give insights into the current state of practice...
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.
