About AUTomotive Open System ARchitecture

AUTOSAR is an open and standardized automotive software architecture, jointly developed by

automobile manufacturers, suppliers, and tool developers.

• Main Goal: introduce a standardized layer between application software and the hardware of an

electronic control unit (ECU)

• Benefit: The software is largely independent from any chosen microcontroller and carmaker,

making it reusable for several individual ECU systems.

• EB: is one of the founding members and an active premium partner of the AUTOSAR consortium

The EB tresos software completely conforms with AUTOSAR 4.x and previous releases
