The invention relates to a hierarchical control system for intersections of a networked motorcade in a cooperative vehicle infrastructure environment. The hierarchical control system comprises an information acquisition module and a hierarchical control module, wherein the hierarchical control module comprises an upper-layer control module and a lower-layer control module; the information acquisition module is used for acquiring signal lamp information and head vehicle driving information, the information acquisition module is respectively connected with the upper-layer control module and the lower-layer control module and is used for transmitting the acquired information to the upper-layer control module and the lower-layer control module, and the upper-layer control module and the lower-layer control module are mutually connected. A layered control framework is adopted, upper-layer control optimizes the speed of a vehicle based on the vehicle-road cooperation technology and controls the vehicle to run at the optimal speed, and lower-layer control performs collision avoidance control on the vehicle according to the critical collision state of the vehicle, so that rear-end collision accidents of front and rear vehicles are prevented; the technical effects of improving the traffic efficiency of the intersection and reducing the overall energy consumption of the motorcade are achieved.
