AUTOSAR - Introduction

AUTomotive Open System ARchitecture:

• Is an open and standardized automotive software architecture, together developed by automobile manufacturers, suppliers and tool developers.

• Hardware independent Software layer.

• Transferability of functions.

• Redundancy activation.

AUTOSAR Key Topics:

AUTOSAR provides three main areas of results:

Architecture:

Software architecture including a complete basic (environmental) software stack for an ECU as an integration platform for hardware independent SW applications

Methodology:

Exchange formats (templates) to enable a seamless configuration process of the basic software stack and the integration of application software in ECUs

Application Interfaces:

Specification of application interfaces as a standard for application software modules 

Benefits from AUTOSAR:

OEM:

• OEM overlapping reuse of software modules
• Maintaining ability to compete on innovative functions, enlarged design flexibility
• Simplification of the integration task
• Reduction of total SW development costs

Supplier:

• Reduction of version proliferation
• Development partitioning among suppliers
• Increase of efficiency in functional development
• New business models possible

Tool provider:

• Common interfaces with development processes
• Seamless, manageable, task optimized (time dependent) tool landscape

New market entrant:

• Transparent and defined interfaces enable new business models
