COVESA & JASPAR Collaborate to Accelerate SDV API Standardization
Share
For those who joined us in Porto this April, the opening keynote of the COVESA All Member Meeting offered a first-hand look at a milestone moment, as JASPAR announced its collaboration with COVESA.
Expanding on this, the organizations also announced today the signing of a Memorandum of Understanding (MoU) [English, Japanese], formally establishing active cooperation on standardized APIs built on COVESA’s Vehicle Signal Specification (VSS) and Vehicle Information Service Specification (VISS).
As vehicle architecture rapidly evolves, standardized APIs and data models have become critical to enabling interoperability, scalability, and faster development cycles across the industry. These capabilities help unlock new business opportunities in the SDV era.
Introducing JASPAR and Yoriito
JASPAR (Japan Automotive Software Platform and Architecture), led by Japan OEMs including Toyota, Honda, Nissan, and other Japan Tier 1s, is actively driving vehicle software development and standardization initiatives originating from Japan.
As part of the Porto announcement, JASPAR also provided a first look at Yoriito, its new open-source project for vehicle APIs. It leverages COVESA’s VSS and VISS technologies and features more than 1,000 APIs and over 370,000 lines of member-contributed code. Yoriito represents a significant step toward scalable, real-world implementation.
Driving Business Value Through Standardization
This collaboration reflects a shared focus on delivering outcomes that matter to the industry. Standardized APIs and data models are foundational to unlocking new revenue streams and efficiencies in the SDV era.
Through this MoU, COVESA and JASPAR will combine standardization with practical implementation through APIs and open-source projects like VSS, VISS, and Yoriito. This ensures that innovation is technically robust but also commercially viable.

Looking Ahead: Expanding Collaboration in Japan
At Automotive World 2026 in Tokyo (September 9–11), COVESA will host a dedicated member pavilion featuring 18 kiosks. The event will also include a keynote presentation, panel discussions, introductory sessions, and technical presentations covering topics such as VSS, VISS, VDM, CDSP, and the Capabilities-Driven Vehicle.
“We have been engaged in domestic standardization activities based on our belief that, for Japan’s automotive industry to continue developing as a core industry, it is essential to deepen collaboration between the automotive sector and other industries, and to keep pace with the speed of change in the SDV era. The signing of this MoU with COVESA marks an important step in taking these efforts global, and in driving standardization and implementation forward as a unified effort. Going forward, we will contribute to the practical adoption of international standards through vehicle APIs and open-source implementations, and work to create value across the industry as a whole.”
