The invention relates to an intelligent network connection vehicle intersection coordinated driving control method and system and a computer readable storage medium. The intelligent network connection vehicle intersection coordinated driving control method comprises the following steps: S1, establishing a directed graph of a road network topology by adopting a graph theory method; s2, extracting state characteristics of the intelligent network connection vehicle by using a two-dimensional grid coding method, and converting the state of the intelligent network connection vehicle into a binary vector; s3, constructing a first reinforcement learning sub-model for exciting the vehicle to quickly arrive at the terminal point; s4, constructing a second reinforcement learning sub-model for avoiding vehicle collision; and S5, fusing the first reinforcement learning sub-model and the second reinforcement learning sub-model to form a fusion model, and calculating to obtain an optimal behavior of global return in a maximized environment. According to the method, unnecessary parking of the vehicle can be avoided, the global return at the intersection is maximized, and the generalization ability is high.
