    Understanding the Purpose of AUTOSAR

    AUTOSAR, short for Automotive Open System Architecture, is a standardized software architecture framework that aims to standardize the software development process in the automotive industry. It provides a common platform for OEMs, suppliers, and tool developers to collaborate and develop standard applications in a seamless manner. This standardization enables modularity, scalability, and portability of software components among different Electronic Control Units (ECUs) across various automotive platforms.

    The primary focus of AUTOSAR is to simplify the development process, reducing time and cost by avoiding software redundancy, improving software quality and reliability, and making automotive software components easily integrable. This can be achieved by providing “templates” for software development, testing, and maintenance activities hence freeing the developers from the tedious tasks of writing code for low-level and complex functions.

    Standard Protocols: Empowering the Application Layer

    One significant advantage of AUTOSAR is its provision of standard protocols for the software component within the application layer. These protocols enable developers to create simple applications that support car’s functions, including power steering, brake system, engine control, and more. Standardization of protocols ensures that there is consistency in the implementation of functions across different car brands and models.

    AUTOSAR adheres to the Model-Driven Development (MDD) approach that relies on mathematical models for the creation of software components. The application of MDD aids in creating abstract models and interfaces, which serve as the basis for developing the software applications. AUTOSAR supports the use of generic models, which means software components could be used across different car brands and models. This is in contrast to proprietary software components, which are exclusive to a single car brand.

    Simplifying Car Functions through AUTOSAR

    AUTOSAR ensures that developers are not burdened with complex and low-level functions that could easily cause errors along the development chain. Instead, developers could concentrate on creating high-level functions that support the car’s application layer. AUTOSAR abstracts the layers under the application layers, which means software developers could work on a black-box system rather than dealing with the complexity of development.

    With AUTOSAR, developers could reuse templates, called Basic Software Modules (BSM), for functions that are common in different car brands and models. This feature dramatically reduces development time and costs by avoiding redundancy. AUTOSAR ensures that the BSM modules comply with the software quality standard across the automotive industry.

    The Role of Software Components in AUTOSAR

    Software components play a key role in AUTOSAR, providing the building blocks for the development of automotive software applications. In AUTOSAR, software components are classified into two groups: Complex Device Drivers (CDDs) and Application Software Components (SWCs).

    The CDDs provide low-level functions for hardware devices, such as sensors, actuators, and communication devices. The SWCs, on the other hand, provide high-level functions, such as vehicle dynamics control, climate control, and infotainment systems. Both the CDDs and SWCs must comply with AUTOSAR’s specification and standardization.

    Virtual Function Bus: Enabling Communication Between Software Components

    AUTOSAR employs the Virtual Function Bus (VFB) to facilitate communication between software components. VFB provides a unified communication interface that exists between various ECUs, providing an abstraction layer for communication messages and their routing. This ensures that messages are correctly routed across various ECUs in the car, which means that the software components could send messages to each other irrespective of the car’s physical configuration.

    AUTOSAR’s VFB is built on several communication protocols, including Controller Area Network (CAN), Local Interconnect Network (LIN), FlexRay, and Ethernet. Using VFB, developers can encapsulate messages in the form of Service Interface Signals (SIS) and transfer them across different ECUs.

    Advantages of AUTOSAR for the Automotive Industry

    AUTOSAR provides several advantages for the automotive industry, including:

    • Standardization of software development processes, which ensures compatibility and consistency across different car brands and models.
    • Reduced development costs, which are achieved by avoiding redundancy and software errors.
    • Modularity and scalability of software components, which ensures ease of integrating software components across different ECUs and platforms.
