Abstract
Keywords - AUTOSAR standardized application interfaces, software sharing
Today new and cost optimized vehicle functions can be achieved in many cases only by networking the vehicle domains. These networked functions improve the safety of vehicle occupants and of other traffic participants. Furthermore the vehicle emission and fuel consumption is reduced as well as the driving comfort and the fun of driving enhanced.
Electric/Electronics architectures differ from Compact to High End Class vehicles. The challenge of the automotive industry is to manage the complexity, keep the reliability of the E/E-systems at a very high level and reduce costs to gain leeway for innovation.
In order to realize this increasingly complex network of functions within reduced development cycles the usage of standards is necessary which are a stable basis for innovations.
AUTOSAR (Automotive Open System Architecture) provides in addition to an ECU software architecture with a standardized infrastructure and exchange formats also standardized application software interfaces. AUTOSAR Release 3.0 (released end of 2007) includes specifications for standardized application interfaces for the domains Body and Interior, Powertrain and Chassis. For Release 4.0 two new domains are under consideration: Occupant and Pedestrian Safety as well as Human Machine Interface, Telematics and Multimedia.
In the following the usage of the AUTOSAR standard for the integration of application software components from different sources and the relocation of application software components between different ECUs is discussed. An example is given for the Automated Parking Brake (APB) from the Chassis domain.
