The invention relates to a vehicle-road cooperation intelligent vehicle lane changing anti-collision system based on a driving intention, and belongs to the field of traffic informatization. The system comprises a sensing data acquisition module, a collision identification decision module, a lane changing trajectory planning module and an anti-collision control execution module. The anti-collision control execution module accurately controls the brake pressure and the front wheel turning angle of the vehicle according to the corresponding motion control method, and the anti-collision function of the vehicle is achieved. According to the invention, aiming at the problems of limitation of intelligent sensing capability of a single vehicle and unicity of an anti-collision mode in a vehicle driving process, sensing is carried out by fully utilizing the accuracy and wide area of V2X Internet of Vehicles communication of a vehicle-road cooperation system; and in combination with a safe distance collision identification decision method and an emergency lane changing trajectory planning method, the collision risk can be effectively reduced under the technical framework of vehicle-road cooperation, and the safety of drivers and passengers is improved.
