Abstract: At present, service oriented architecture (SOA) occupies an increasingly important role in vehicle software, and communication middleware is one of the key links in the implementation of SOA. The advantages of data distribution service (DDS) in the automotive field have gradually become prominent. But there is little mention in the literature about the deployment and application of DDS on vehicles. The basic principle, publish-subscribe model and quality strategy of service of DDS is introduced in this paper detailly. Then the whole communication process of DDS and three different forms of DDS deployment on vehicles are introduced. Finally, taking FAST DDS as an example, the specific process of DDS deployment on vehicles is introduced in detail. The communication middleware based on DDS has a wider application prospect in automotive industry.
