San Ramon, Calif. and Brussels, 29 July 2025 – The Connected Vehicle Systems Alliance (COVESA) and the European Automobile Manufacturers’ Association (ACEA), today announced the signing of a Memorandum of Understanding (MoU) aimed at achieving industry-wide interoperability for connected commercial vehicles.
The MoU establishes a cooperative framework between COVESA and ACEA to ensure interoperability across truck and bus OEMs through the joint development of a standardised onboard API, specifically designed to support fleet management applications. This collaboration will build upon and extend COVESA’s Vehicle Signal Specification (VSS) by jointly defining an expanded data catalogue tailored to the needs of commercial vehicle manufacturers and fleet managers.
The onboard API is based on transport protocols already supported by COVESA’s Vehicle Interface Service Specification (VISS), which provides access to COVESA VSS data. By enabling consistent data exchange across different vehicle platforms, this initiative aims to enhance integration, efficiency, and scalability for commercial vehicle solutions across the industry.
