Systematic Use of the AUTOSAR Standardized Application Interfaces

Abstract : The AUTomotive Open System ARchitecture (AUTOSAR) initiative develops an open standardized software architecture for automotive electronics. The partnership is focused on managing the growing complexity in the development of automotive electric/electronic architectures, with the aim of enabling new technologies and improving development efficiency – without making compromises on quality and limitation of corporate identity. AUTOSAR mainly concentrates in the standardization on three pillars. First, a layered architecture for electronic control units (ECU) is defined and the lower layers, the basic software (BSW), is standardized on module level. Second, a methodology enables the configuration of systems within a collaboration process between OEMs and suppliers. Third, on the highest architectural layer, SW-components and their application interfaces are standardized. Especially in this third pillar, the standard does not structure the SW-components with respect to functional vehicle models, neither for existing nor for future ones. Therefore, the link between the functional view on a vehicle and the SW architecture is still missing. This paper presents the standardized application interfaces as part of the SW-architectures in usual vehicles. We embed the interfaces into a new framework that serves as a link between these SW- architectures and functional vehicle models. As the functional models are normally OEM specific and differ from each other, the framework can be seen as the necessary glue to realize different vehicles with the help of the AUTOSAR standardized components. The concept will be validated with the help of a functional model developed by Siemens VDO Automotive AG. This functional model serves as a validation of the framework. One main advantage of this framework is, that it enables the simulation of the behaviour of the components, i.e. the ECUs, on vehicle level.
