The invention discloses a vehicle game lane changing cooperation method in an Internet of Vehicles environment. The method comprises the following steps: 1, determining action spaces of a lane changing vehicle and a rear vehicle; 2, identifying a lane changing type, if the lane changing type of the lane changing vehicle is free lane changing, executing the step 3, and if the lane changing type ofthe lane changing vehicle is forced lane changing, executing the step 4; 3, selecting the revenue functions of the lane changing vehicle and the rear vehicle in the free lane changing, and then executing the step 5; 4, selecting the revenue functions of the lane changing vehicle and the rear vehicle in forced lane changing, and then executing the step 5 ; 5, calculating the revenue functions, andconstructing a revenue matrix; 6, for the constructed revenue matrix, solving all Nash equilibrium decision combinations; and 7, outputting a cooperation scheme. According to the invention, lane changing cooperation among drivers is guided, the lane changing efficiency of vehicles is improved on the premise of ensuring traffic safety, the traffic capacity of road sections is further improved, anda theoretical basis and a feasible scheme are provided for constructing a lane changing driving auxiliary system.
