The invention relates to a multi-intelligent-network-connected-vehicle cooperative confluence control method for a high-speed ramp entrance. An upper-layer traffic management system, a central controlsystem, controlled intelligent network connected vehicles and V2I communication equipment are included. Wherein the upper-layer traffic management system limits the vehicle confluence safety time interval and the confluence speed, and sends a limiting requirement to the central control system at the same time; the V2I communication device obtains information flow of the real-time driving state ofthe controlled intelligent network connection vehicle and sends the obtained information flow to the central control system; the central control system carries out integrated calculation on the acquired various limitation requirements and real-time driving state information, and sends an optimal control quantity instruction to the controlled intelligent network connection vehicle through V2I communication equipment; according to the method, the potential safety hazard of road traffic is relieved, the negative influence of the expressway entrance ramp on the main road traffic flow is reduced,and meanwhile the problem that an existing ramp confluence vehicle trajectory planning method is large in calculated amount and difficult to apply to a real-time controller is solved.
