Abstract:  This paper proposed the concept, structure, function and working principle of the system of coordinated control by vehicle- road-cloud Integration (as called cloud control system : CCS). It is a typical application of cyber-physical system theory in the field of intelligent and connected vehicles. The CCS has five features: ubiquitous interconnection of vehicles, roads and clouds, digital mapping of all traffic elements, global performance optimization, efficient computing and scheduling, and high reliability of system operation. It involves basic technical features such as integrated technology of vehicle – road - cloud and dynamic resource scheduling technology. Two typical applications of the CCS are introduced: Cloud-controlled Economic Driving System (CloudEDS), Cloud-controlled Traffic Control System (CloudTCS). The two system based on the technology of CCS can significantly improve the performance of vehicle driving and traffic operation safety and efficiency. The CCS needs to be designed from the top-level system planning, industrial environment construction, and unified standards. Furthermore, the implementation of technologies and industrial applications is necessary.

Key words: intelligent and connected vehicles (ICVs), automated driving, cloud control system(CCS), base platform for cloud control, cloud economic driving system (CloudEDS), cloud traffic control system (CloudTCS)
