AUTOSAR Overview and Classic

AUTOSAR Overview

• AUTOSAR (Automotive Open System Architecture) is an open standard for automotive software architecture
• It provides a common infrastructure for automotive systems, enabling scalability, flexibility, and maintainability

AUTOSAR Classic

• AUTOSAR Classic is a specification for automotive systems, focusing on the application layer
• It provides a set of APIs and interfaces for automotive applications
• Key components:
  • Runtime Environment (RTE): provides a platform for executing automotive applications
  • Basic Software (BSW): provides a set of basic software modules for automotive systems
  • Application Software (ASW): provides automotive-specific applications

Vehicle Computer

• A Vehicle Computer is a central computing platform in an AUTOSAR system
• It integrates various automotive systems, such as powertrain, safety, and infotainment
• Key features:
  • High-performance computing
  • Real-time operating system
  • Support for multiple automotive busses (e.g., CAN, LIN, FlexRay)

Communication Stack

• The Communication Stack is a key component of AUTOSAR, enabling communication between automotive systems
• It consists of three layers:
  1. Physical Layer: defines the physical communication medium (e.g., CAN, LIN, FlexRay)
  2. Data Link Layer: provides error-free data transfer between nodes
  3. Network Layer: routes data between nodes and manages network topology
• Key protocols:
  • CAN (Controller Area Network)
  • LIN (Local Interconnect Network)
  • FlexRay (high-speed communication protocol)

Software Architecture

• AUTOSAR Software Architecture is based on a layered architecture
• Key layers:
  • Application Layer: provides automotive-specific applications
  • Runtime Environment Layer: provides a platform for executing applications
  • Basic Software Layer: provides basic software modules for automotive systems
  • Microcontroller Abstraction Layer: provides a interface to the underlying microcontroller
• Key benefits:
  • Scalability and flexibility
  • Reusability of software components
  • Improved system maintainability and reliability
