This paper builds a decision model for intelligent networked vehicles (ICV) lane changing behavior based on the idea of game theory. Focusing on the complex traffic conditions of three-lane highway with multi-vehicle interaction and competition, we solve the ICV lane change decision problem by pairing ICVs two by two, formulating a multi-group game and comparing the game gain results to find the best. Based on Time-to-Collision (TTC), we design the payoff function of this decision model game so that the game results in a pure strategy Nash equilibrium (PSNE), and obtain the unique optimal lane change decision for a given state by designing the objective function of the lane change game. The joint simulation by PreScan/Simulink/CarSim software verifies the rationality of the payoff function and the validity and applicability of the lane-changing model.
