融合轻量级DDS的智能车通信架构设计

Design of Intelligent Vehicle Communication Architecture Based on Lightweight DDS

针对汽车传统分布式电子电器架构通信网络高复杂度、紧密耦合的问题,设计并实现了基于DDS服务的智能车通信架构,通过在嵌入式ECU中移植轻量级DDS中间件,解决了资源受限设备与标准DDS无法直接通信的局限性。实车测试表明:该通信架构具有更好的QoS性能,系统的平均通信时延小于3 ms,满足实时性的需求。

Aiming at the problem of high complexity and close coupling of communication network in traditional distributed electronic and electronic architecture of automobiles, an intelligent vehicle communication architecture based on DDS service was designed and implemented. By integrating lightweight DDS middleware into embedded ECU, the incapability of direct communication between resource-constrained equipment and standard DDS was solved. The real vehicle test shows that the communication architecture has better QoS performance. The average communication delay of this system is less than 3 ms, which meets the real-time requirements.
