Electrification is the foundation of intelligent and connected vehicles. As the automobile industry is evolving more and more from fossil fuels to sustainable power resources, the construction of vehicles is gradually shifting to electrified architecture. As a result, the management and control of various parts of the vehicle have become a core factor in electrification.
The increasing application of driverless and driver assistance systems is pushing the intelligence of connected vehicles to a new level. Coordinating in-vehicle sensors, controllers, actuators, and in-vehicle system modules enables them to have complex environmental perception and intelligent decision-making and control functions. This is the key to the entire intelligence.
Driven by the demands of emerging advanced vehicular applications, large-scale automotive networks, and mobile networking, traditional V2X is evolving to Internet of Vehicles (IoV). This ubiquitous network will enable humans, vehicles, and other infrastructure elements to sense each other and share information. Connectivity is fundamental for building the autonomous system of automobiles.
EMQ provides multiple protocol access. It not only guarantees vehicles’ massive TBox connections via diverse protocols, it also collects, processes, and analyzes messages from the Electrical/Electronic Architecture, Automotive OS, Cooperative Vehicle Infrastructure System, Autonomous Driving System, and other sub-systems at the network edge. EMQ adopts front-end and back-end separation and a fully asynchronous, distributed cluster architecture. This provides better support for the access of MQTT, GB/T32960, JT/T808, and other IoV protocols.
EMQ interconnects road-side infrastructure, such as cameras on road, MMW radar, laser radar, and MEC to support CVIS applications. It coordinates the road-side infrastructure, in-vehicle units at edge, and applications in the cloud and powers the information exchange capability of V2X.
Connected vehicle networks and autonomous driving require real-time and highly concurrent data exchange at the application level. EMQ is built on the Erlang/OTP platform, a language platform characterized by soft real-time, low latency and distributed, which serves the purpose of IoV very well.
EMQ provides an extensible authentication and authorization chain. It supports authentication via an internal or external DB, certificates, and third-party platforms, and it supports TLS/DTL encrypted transmission and bi-directional certificate authentication. EMQ protects access and provides complete data security.
EMQ’s distributed cluster architecture enables horizontal expansion; it supports node automatic discovery, auto clustering, auto-healing from a network partition, and auto removal of a downed node. EMQ’s layered modular design supports multi-language extension. EMQ provides a highly reliable and easy-to-expand overall architecture, and ensures a reliable and available interconnection layer for the intelligent network system.
Based on the overall architecture of the IoT infrastructure, EMQ supports scenarios such as the Internet of Vehicles, intelligent driving, and vehicle-road collaboration, and it simplifies the infrastructural construction of IoT applications.
10-million-level device interconnections. Supports MQTT and many protocols that are widely used in IoV applications. Coordinates the people, vehicles, roads, and the cloud.
EMQ’s soft real-time, low latency, and high concurrency, satisfies the needs of autonomous driving, CVIS, ITS, and many more applications.
Bi-directional authentication, access control, and secure transmission guarantee the reliability of IoV applications.
EMQ’s distributed, dockerized, elastically extensible, and auto-scalable ways of deployment ensure the high reliability and high availability of IoV applications.
