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.
