AUTOSAR on the Road

2008-10-20
2008-21-0019
The AUTomotive Open System ARchitecture (AUTOSAR) Development Partnership has published early 2008 the specifications Release 3.0 [1], with a prime focus on the overall architecture, basic software, run time environment, communication stacks and methodology. Heavy developments have taken place in the OEM and supplier community to deliver AUTOSAR loaded cars on the streets starting 2008 [2]. The 2008 achievements have been: Improving the specifications in order to secure the exploitation for body, chassis and powertrain applications Adding major features: safety related functionalities, OBD II and Telematics application interfaces.

FlexRay - Exploitation of a Standard and Future Prospects

2006-10-16
2006-21-0039
The BMW Group is the first car manufacturer introducing FlexRay in series projects. Start of production is September 2006, where a pilot application is implemented in the chassis domain of the new BMW X5. In 2008 FlexRay will form a substantial part of the overall electronics architecture in form of a FlexRay network connecting multiple ECUs implementing chassis, powertrain, and driver assistance applications.

Achievements and Exploitation of the AUTOSAR Development Partnership

Reductions of hardware costs as well as implementations of new innovative functions are the main drivers of today's automotive electronics. Indeed more and more resources are spent on adapting existing solutions to different environments. At the same time, due to the increasing number of networked components, a level of complexity has been reached which is difficult to handle using traditional development processes. The automotive industry addresses this problem through a paradigm shift from a hardware-, component-driven to a requirement- and function-driven development process, and a stringent standardization of infrastructure elements. One central standardization initiative is the AUTomotive Open System ARchitecture (AUTOSAR). AUTOSAR was founded in 2003 by major OEMs and Tier1 suppliers and now includes a large number of automotive, electronics, semiconductor, hard- and software companies.

Intelligent Automotive System Services - An Emerging Design Pattern for an Advanced E/E-Architecture

2006-04-03
2006-01-1286
The paper will introduce the concept of intelligent automotive system services as an essential pattern for forthcoming Electric/Electronic (E/E) architectures. System services are infrastructure-related, having vehicle-wide functionalities with one central part (master) and optionally several peripheral parts (clients) as counterparts in every ECU. System services support the reliable operation, efficient administration and maintenance of car functions over the entire life cycle. System services constitute vehicle-wide, distributed functionalities. Therefore, a consistent, interoperable and scalable implementation and integration strategy is outlined. In addition, synergies to the standard core as well as to the AUTOSAR concept will be described.

The key-enabler for tomorrow's X-by-wire systems is the mastery of today's advanced active chassis control systems that are highly safety critical, distributed and complex. The only feasible way is to compose future X-by- wire systems with established and field approved functional management, components and infrastructure technologies, which are addressed in this paper.

BMW's Approach of Vehicle Functions and Systems Orientation for Developing Innovative Powertrains

2004-10-18
2004-21-0065
The dramatic increase in data and information exchange has lead to increased communication network complexity within the subsystems of the powertrain itself as well as in all other subsystems of the vehicle. It is essential to manage this complexity during the development process. Applying new processes and methods such as vehicle functions and systems orientation in a top-down structural approach creates a powerful support in development of innovative powertrains. Several technical integration examples of powertrain functions are illustrated for the purpose of demonstrating customer-related advantages. Vehicle functions and systems orientation also has significant impact on organisational structures and cooperation methods to achieve maximum synergies as well as efficient vehicle communication architectures.
