AUTOSAR Tools. Q&A: Autosar's implications for auto engineers. AUTOSAR Tooling | BMW Car IT. Community Tool Development for AUTOSAR Today, many large software projects are done in a community approach, which means that developers from various companies collaborate and share the code they write. The code is usually provided under a certain open source software license which gives others the right to use it free of charge but also encourages them to improve it and share their work. The project "Artop (AUTOSAR Tool Platform)" uses the community model for development of a base infrastructure for AUTOSAR tools within the AUTOSAR development partnership. Artop’s goal is to bring the benefits of the open source approach within the legal constraints of the AUTOSAR partnership. Artop - Autosar Tool Platform Artop is a base platform, designed to assist and accelerate the development of AUTOSAR tools.
BMW Car IT has used Artop in various projects with BMW AG to foster the introduction of AUTOSAR and to fulfill special customer needs. ARText - Efficient Modeling! ARUnit - Efficient Testing! Easing Design Process with AUTOSAR Standard Support. By Eric Tinlot Today’s vehicles have up to 70 electronic control units (ECUs) supporting many of their in-vehicle functionalities—a result of tougher constraints in areas including security, environment, comfort and safety.
All of these functionalities call for simultaneous interactions by sensors, actuators and control units. But with the complexity of signal interactions among ECUs, this can be a challenging prospect. What’s more, these complex interactions and the increasing number of ECU nodes are increasing the amount and complexity of software required. The Automotive Software Platform and Architecture (AUTOSAR) is an open and standardized automotive software platform and architecture jointly developed by automotive manufacturers, suppliers and tools developers. Because it provides an abstraction layer between hardware and application, the standard allows hardware-independent development and testing of the application software. Like this: Like Loading... Multicore on AUTOSAR | BMW Car IT. Modern cars are highly complex systems consisting of a huge number of mechanical and electrical parts. An observable trend in the automotive industry shows that more and more features and innovations are based on electrics/electronics and therefore on software.
Hence the demand of computational resources in the vehicle is growing rapidly. In the consumer PC and server market multi-core processors have become the method of choice to meet the ever increasing demand for computing power. So why not just use multi-core CPUs in the automotive domain ? Unfortunately, it is not as simple as that. The application in the automotive domain poses a different set of requirements on software and hardware and the increasing complexity of the electric systems in modern car necessitates the use of sophisticated methods for development and verification. AUTOSAR is a key technology to manage this increasing complexity. 2007: Initial experiments with multiple operating systems and architectures.
Infosys – Autosar Electronic Software Systems | Control Unit. Autosar and VSA from Mentor Graphics - June 29, 2009. AUTOSAR Methodology Breaks Down Complex Auto System Design. Today’s state-of-the-art automobiles have become increasingly complex systems comprised of integrated hardware and software components. Many of these embedded systems incorporate engineering control unit (ECU) technology. Before these cars can be brought to market, auto manufacturers and top-tier suppliers look to leverage AUTOSAR-compliant (Automotive Open System Architecture) technology to enhance the quality and efficiency of automotive design. A recent survey of 150 German AUTOSAR experts found that more than 55% of all electric/electronic (E/E) development projects will be based on AUTOSAR technology within the next five years. Due to the growing complexity of these E/E systems, manufacturers and suppliers look to identify software-development tool vendors that can provide the capabilities to develop AUTOSAR-compliant solutions.

NEC Electronics Activities in Automotive: AUTOSAR | Renesas Electronics. NEC Electronics Europe Automotive Business Group Senior Engineer Peter Jakobsson Increasingly complex automotive electrical and electronic control systems are being implemented for controlling engines, brakes, and other functions to enhance vehicle safety and environmental friendliness.
Particularly in the development of the Electronic Control Unit (ECU), the software component has become enormously important, so efficient development of software has emerged as a critical issue. To meet this challenge, the AUTOSAR (Automotive Open System Architecture) partnership was formed, a standardization consortium consisting of vehicle manufacturers, ECU suppliers, microcontroller (LSI) vendors and software development tool vendors. Since NEC Electronics joined the consortium as a premium member, the company has become actively involved in standardization work to build a common platform for software development.
We asked Peter Jakobsson with NEC Electronics Europe about the activities in AUTOSAR. NEC Electronics Activities in Automotive: AUTOSAR | Renesas Electronics. Vehicular Electronics Laboratory: AutoSAR. AUTOSAR (AUTomotive Open System ARchitecture) was formed in July 2003 by the automotive manufacturers BMW Group, DaimlerChrysler and Volkswagen, and by the automotive system suppliers Bosch, Continental and Siemens VDO(now Continental AG). It provides an open and standardized automotive software architecture for developing vehicular software, user interfaces and management. AUTOSAR aims to improve complexity management of highly integrated E/E architectures by high reusability and exchangeability of Software modules between OEMs and suppliers. It aims to standardize the software architecture of ECUs and paves the way for innovative electronic systems that improves the performance, safety and environmental friendliness.
The hardware and software will be widely independent of each other reducing the development time and costs. The reuse of software by OEMs and the suppliers also helps to increase the quality and efficiency. The second layer is the ECU abstraction layer. Mentor Graphics, Mecel offer Autosar 4.x software design solution.
