Latest Trends In Automotive Electronic Systems, Highway Meets Off-Highway

摘要

The rapid development of electronic systems in automotive vehicles has been driven for decades by constantly growing requirements of legislation for environmental protection, as well as rising demands of the end-user to improve fuel economy, safety, driving comfort and to handle the system complexity. The manufacturers of mobile work machines also see themselves increasingly confronted with these requirements. Can we use the technical experiences from automobiles also in this area to efficiently develop high-quality electronic systems that are future-oriented and able to flexibly adapt the systems to different platforms? The answer to this question should be "yes - we can"! One of the future challenges will be the optimized re-use of software functions engineered by different manufacturers and suppliers for vehicles and systems. In the automotive industry this attempt is being undertaken by different companies under the name AUTOSAR and with software sharing concepts. Additionally, the software development is done in compliance to standards like CMMI or SPICE which ensure a consistent, high quality product. The exchange of information between control units makes the interaction of the systems much more complex and asks for more efficient, faster data communication systems by new standards, such as the bus system FlexRay.
