The initiative is designed to support flexibility in product modifications, upgrades, and updates, while leveraging scalable solutions within and across product lines. Enhancing scalability and flexibility in the integration and transfer of functions is a key objective, aiming to improve the quality and reliability of software and E/E systems. The goals of AUTOSAR include addressing future vehicle requirements such as availability, safety, software upgrades, updates, and maintainability. AUTOSAR seeks to enhance scalability and flexibility for function integration and transfer. Additionally,

This virtual bus is an abstract set of RTEs that are not yet deployed to specific ECUs and decouples the applications from the infrastructure. It communicates via dedicated ports, which means that the communication interfaces of the application software must be mapped to these ports. The VFB handles communication within
