In the design and development of the next-generation intelligent car connectivity system at SAIC Volkswagen, we referenced a large number of mainstream domestic and international new-generation car networking system architectures. EMQX, based on the MQTT protocol, possesses characteristics such as high concurrency, low latency, and high throughput, making it highly suitable for our car networking application scenarios. This has achieved a loose coupling between the car networking system and the in-car system, simplifying the interaction process. This allows our team to focus on upper-level car networking application development. Additionally, EMQX products exhibit excellent scalability and horizontal expansion capacity in terms of management, providing robust support for the large-scale integration of new vehicles and other models in the future.
