AUTOSAR Basics

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.”

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

THE BENEFITS OF AUTOSAR

A GLOBAL STANDARD CREATED IN COLLABORATION WITH PARTNERS

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
