Jointly-developed by automobile manufacturers, electronics and software suppliers and tool vendors and developers. Responsible for real time functions, priority based scheduling and different protective functions. Download for free Report this document.
More than member companies Homepage : www. Such ECUs have the following properties: Strong interaction with hardware sensors and actuators , Connection to vehicle networks like CAN, LIN, FlexRay or Ethernet, Microcontrollers typically 16 or 32 bit with limited resources of computing power and memory compared with enterprise solutions , Real Time System and Program execution from internal or external flash memory. The standard comprises a set of specifications describing a software layered architecture implemented in every ECU and frees the applications software from the hardware components and defining their interfaces.
Each function had its own system and microcontroller although they may communicate through a bus. Hardware and software were tightly connected. The same vendor supplies both hardware and software. There are no alternative software suppliers. What will AutoSar give? A standard platform for vehicle software. An OS with basic functions and interface to software. The same Standardized uniquely-specified interface for all basic software.
Functionality is supplied as software components. These components are hardware independent. The software modules are exchangeable and reusable between OEM and suppliers. More than one supplier can compete with their software. Allow software Reuse of software increases at OEM and at suppliers and smooth evolutions limiting re-development and validation , this reduces development time and costs.
This enhances also software quality and efficiency and easily handling of electronic in the automobile. Facilitate portability, composability, integration of SW components over the life time of the vehicle.
This allows fast and pragmatic improvements. The previous benefits are for all type of stockholders. Methodology: Exchange formats or description templates to enable a seamless configuration process of the basic software stack and integration of application software in ECUs and it includes even the methodology how to use this framework.
Application Interfaces: Specification of interfaces of typical automotive applications from all domains in terms of syntax and semantics, which should serve as a standard for application software modules.

Automotive Software Architectures pp Cite as. AUTOSAR defines the reference architecture and methodology for the development of automotive software systems, and provides the language meta-model for their architectural models. It also specifies the architectural modules and functionality of the middleware layer known as the basic software. We then describe the proposed development methodology by identifying major roles in the automotive development process and the artifacts they produce, with examples of each artifact. We follow up by explaining the role of the AUTOSAR meta-model in the development process and show examples of the architectural models that instantiate this meta-model. We conclude the chapter by showing trends in the evolution of the AUTOSAR standard and reflect on its future role in the automotive domain.
