EMQ Showcases Open-Source Leadership in Software-Defined Vehicles at OSSummit Japan

TOKYO, JAPAN, December 10, 2025 – EMQ, the world's leading provider of open-source MQTT messaging and IoT data infrastructure, today highlighted its impactful contributions to the evolution of Software-Defined Vehicles (SDV) and the Internet of Vehicles (IoV), following its participation in the Open Source Summit Japan.

EMQ's Solution VP, Jaylin Yu, delivered two insightful sessions at the conference, emphasizing the practical application and hardening of open-source software in mission-critical automotive environments.

Pioneering OSS in Real-World Automotive Production

In the Automotive Linux Summit track, Yu’s presentation, "Open Source in Action: Pioneering OSS in Real World Production," detailed how EMQ tackles in-vehicle performance tuning and ensures guaranteed data delivery.

Later, in the Safety Critical Software track, Yu’s talk, "Driving Safety Forward: Lessons Learned From Deploying OSS in Real-world Automotive," addressed the gap between OSS adoption and stringent automotive safety and security demands. He shared EMQ’s story of bringing OSS into mass production vehicles, including the crucial impact of a healthy open-source community, academic research (like fuzzing technology) in solving security gaps, and approaches to lowering software supply chain dependency risk for MQTT-based remote diagnostics.

EMQ's Unified Data Backbone for SDV: Forging the Data Closed-Loop

"To fulfill its potential in Automotive, the industry must move beyond simply adopting code and focus on building a strategic, healthy ecosystem of contribution and maintenance," said Jaylin Yu. "This requires an action-first mentality, learning from our past mistakes to chart a safer course forward."

EMQ champions the data closed-loop approach for successful SDV development, distinguishing vehicles defined by software from those merely with software functions. This continuous loop, turning static vehicles into dynamic intelligences, is powered by the EMQX SDV-Flow platform, a Unified MQTT Data Backbone.

  • Architecture Decoupling: Facilitates Service-Oriented Architecture (SOA) by creating a decoupled databus, enabling faster innovation and independent application deployment.
  • Seamless Protocol Bridging: Integrates diverse DCUs by bridging legacy protocols like CAN and SOME/IP with modern standards.
  • Optimized Data Flow: Achieves Data Persistence using Apache Parquet for storage efficiency and Stream Processing for real-time decision-making, while powering V2X Communication.

Real-World Success:

EMQ’s solution is proven in mass production:

  • It powers the TSP platform for millions of Geely electric vehicles, handling 100k+ messages/sec globally.
  • It provides the real-time data backbone for UISEE Autonomous Driving, ensuring ms-Level Low Latency and 99.99% Reliability.

Outlook: Scaling Context, Not Just Data

Looking ahead, EMQ remains committed to the open-source philosophy, viewing the community as an essential partner in hardening and advancing automotive technology.

“As the industry rapidly digitizes, the future of SDV relies not just on scaling data, but on scaling context,” added Jaylin Yu. “By providing a resilient, open-source backbone for data collection and processing, EMQ is focused on transforming raw telemetry into high-fidelity, actionable intelligence that drives the next generation of safe, reliable, and evolving Software-Defined Vehicles.”
