1 Automotive Open System Architecture AUTOSAR
AUTOSAR Description:
AUTOSAR (Automotive Open System Architecture), automotive open system architecture Alliance is a global automotive manufacturer , component suppliers and other electronics, semiconductor and software companies jointly established, the members keep the development partnership. Since 2003, each partner companies work together, committed to the automotive industry to develop an open, standardized software architecture. The AUTOSAR architecture facilitate the exchange of vehicle electronic systems and software updates, and provides a foundation for the efficient management of increasingly complex vehicle electronics, software systems. In addition, AUTOSAR ensure product and service quality, while improving cost efficiency.
AUTOSAR applications:
BMW Group began in architecture called BMW Standard Core, the use of standardized basic software in the ECU electronic control unit since 2001. The software covering all aspects of vehicle management system functions, including the implementation (such as vehicle energy flow management systems, parking preparatory function), system management (system of coding and diagnosis), to customize the system (such as a customization feature can be set special conditions of service customization).
now used in the new 7 Series BMW Standard Core software system to achieve the on-board network, system memory management, and system diagnostics through most of the AUTOSAR architecture. In addition, new BMW 7 Series operating system used by a plurality of ECU AUTOSAR architecture matches, allowing each application independently. Such as a central gateway, which ensures that the ECU external I / O systems (CAN-bus and Ethernet) connected to the internal I / O between the system bus (CAN, MOST, FlexRay) high-speed broadband. It also can adjust the number of kernel functions, such as condition monitoring, and system encodingEnergy consumption detection.
on the future development of the electronic control unit ECU, the BMW Group firmly supported the application, the promotion of AUTOSAR architecture. A well-crafted plan has been implemented, the relevant suppliers are also included in relevant planning. For the drive system, chassis, safety systems, interior and body of R & D applications already in full swing.
In Elmar Frickenstein view, the advantages of AUTOSAR architecture are obvious: ldquo; future models will generally benefit from a unified industry-wide standardization of procedures, as well as versatility, interchangeability of more software. AUTOSAR standardization and application interface software vendor universal tool will facilitate the further development of the sector.
AUTOSAR in China:
major domestic automobile manufacturers, research institutions are increasingly concerned to bring standardized AUTOSAR design, development, verification, thereby a substantial increase in R & D efficiency and quality of research and development of automotive electronics.
Experimental Center ESE Zhejiang University from 2004 began to focus on AUTOSAR, and the first to join the AUTOSAR organization. Currently ESE Experimental Center, Zhejiang University has successfully developed an integrated set of development tool chain ECU AUTOSAR-compliant (referred to as SmartSAR Studio), it can be used for ECU software architecture, network system configuration, basic software core configuration, diagnostics, calibration and simulation testing, support from top to bottom, fast iterative software development model as the center. In addition, ESE has developed a laboratory center operating system, communications and other basic software modules conform to the AUTOSAR standard.
FAW, Changan automobile factory Institute of Technology in 2009, also started to use standard tools for AUTOSAR ECU design, development, verification.
It is noteworthy, iSOFT INFRASTRUCTURE Software Co., Ltd. (iSOFT), as a member of Autosar, CASA has set up a joint alliance in China SAIC, FAW, Changan, Chery and other major OEM and some institutions, China aims to promote and develop Autosar architecture. Waterhouse Autosar already have a series of tool-based chain, such as OrientaisStudio, BSW configuration tool.
