The invention provides an intelligent network connection automobile cooperation method and system based on risk situation cognition, and belongs to the field of intelligent driving. According to the system, a global risk situation calculation module, a global value-at-risk map superposition module, a risk level quantification module and the like are deployed at a road edge calculation node, and a single vehicle risk situation calculation module, a risk situation fusion calculation module, a driving decision module and the like are deployed at a vehicle node. According to the method, an edge computing node computes various risk situations including obstacle risk situations and collision avoidance situations in real time according to global traffic data of roads, performs superposition and risk level quantification, outputs a global risk situation value map and distributes high-risk targets to networked vehicles; and the vehicle calculates a local risk situation according to local traffic data sensed by the vehicle, and carries out driving decision by fusing the global risk situation. According to the method, the sensing range is expanded, various driving risk influence factors are comprehensively considered, the communication burden of the Internet of Vehicles is reduced, and the scene of real-time collision avoidance situation calculation can be better met.
