The most distinctive characteristic of vehicle network is that the nodes in the vehicle network move at high speed and the topology changes rapidly.

The good communication topology can improve the efficiency of the routing in the network, reduce the communication congestion and communication conflict in the vehicle network. Considering the mobility of vehicle network, topology generation and topology maintenance in clustering control algorithm need to occur frequently, so how to design topology control algorithm, To provide a stable topology for routing in vehicle networks is an urgent problem to be solved. Firstly, based on the study of the similarity between the biological cluster system and the vehicle network, aiming at the typical scene of vehicle network, this paper studies the similarity between the biological cluster system and the vehicle network. The VANETs dynamic prediction model based on Vicsek model is proposed. Based on the VANETs dynamic prediction model, a topology prediction method is proposed, which can predict the topology of vehicle network. We use the network simulation tool NS3 to simulate the topology prediction algorithm. The simulation results show that the method is feasible. Secondly, according to the VANETs dynamic prediction model, the node backbone reliability of the vehicle network is obtained, and the node backbone reliability factor and the node speed factor are creatively considered. Based on the combination of the relative destination factors and the distance and proximity factors of the node distance roadside system, a node reliability evaluation model is proposed, which aims at the close communication scene between the vehicle and the vehicle in the vehicle network. Based on the topology prediction method and node reliability evaluation model, a topology control algorithm for local communication in workshop is proposed. The end-to-end delay and packet rate of the algorithm are simulated. The results show that, The algorithm can adapt to the dynamics of the vehicle network and improve the efficiency of local communication in the workshop. Finally, this paper aims at the typical application scene of the vehicle online communication downloading music from the network through the roadside system. Taking the roadside system into account in the topology control algorithm, a topology control method is proposed to solve the uplink process in which the vehicle sends the request information to the roadside system to download music. The topology control algorithm of the downlink process of downloading music back to the target vehicle by the roadside system. The topology control algorithm of the vehicle online communication takes into account the road side system, the speed factor of the node, the reliability of the node backbone, and so on. Through the simulation of the topology control algorithm, the simulation results show that, with the increase of the number of vehicles, The topology control algorithm has good performance in end-to-end delay and packet rate. The topology control of vehicle network is improved.
