AUTOSAR (AUTomotive Open System ARchitecture) is an open standard for automotive software architecture and interfaces supported by automotive manufacturers, suppliers, and tool providers. The goal is to make automotive ECU software reusable between vehicles and manufacturers by standardizing interfaces. This will improve quality, reduce costs by enabling software reuse, and make modifications and updates more flexible. AUTOSAR defines a layered architecture with standardized application and basic software layers separated from hardware-dependent layers to achieve reusability independent of ECU or microcontroller hardware.

1. AUTOSAR Basics

2. WHAT IS AUTOSAR?
• AUTOSAR – AUTomotive Open System ARchitecture
• AUTOSAR is an initiative supported by the world’s leading
automotive manufacturers, suppliers and tool providers.
• The objective of AUTOSAR is to specify an open standard for the
software architecture and software interfaces for the most
common functionality in ECUs.
AUTOSAR:
“Cooperate on standards, compete on implementation.”

3. WHAT IS AUTOSAR?
• AUTOSAR will make it possible to reuse applications
between ECUs and enable a market for software
products.
• By standardization AUTOSAR will:
• Improve quality, scalability and reliability
• Cost optimize automotive software
• Create flexibility for product modifications,
upgrades and updates

6. WHY AUTOSAR?
Microcontroller
Software
Traditional Development AUTOSAR Development
• Created to accomodate for a changing industry where automotive software is a
product
• Hardware and software need to be less dependent of each other
• Development processes need to be simplified
• Reuse of software increases at both OEMs and suppliers
