Audio Video Bridging (AVB) in an Automotive Ethernet Network
Purpose and goal
The FFI project Ethernet AVB has fulfilled the objectives as defined when the application was made in the end of 2013. The project objectives have addressed the higher-level objectives from a base technology perspective. Research leading to development of new concepts and innovations for synchronized Ethernet communications in the vehicle creates conditions for development of new functions primarily in Active Safety, Autonomous Drive and Infotainment in future vehicles. The synchronization of the Ethernet traffic is achieved by means of the protocols that make up Ethernet AVB.
Results and expected effects
AVB has produced valuable results and knowledge in different automotive Ethernet areas, including: Identification of proper requirements and use cases, creation of a test bench and adaptation of tools for simulation, usage of simulator and test bench for studies of Ethernet AVB for different network configurations and traffic flows, and monitoring and participating in the future development of standards and platforms for Ethernet AVB.
Approach and implementation
The project was structured into the following WPs at the highest level: WP 0: Project Management WP 1: Requirements and Use Cases WP 2: Test Bench WP 3: Analysis & Validation WP 4: Future Standards & Autosar Project Management was based on monthly reports and meetings in the project team, meetings with the steering group at least before each reporting to VINNOVA, meetings within each WP, workshops and project seminars. This approach and realization worked very well in the project.
