In order to overcome the selfishness of users and encourage more vehicles to participate in this process, this paper combined the computing and caching capabilities of mobile edge cloud, proposed a new service caching and delivery incentive mechanism, the main research content is as follows: Aiming at the service caching process, this paper designs a reputation incentive mechanism based on SD-VEC framework. Before the user applies for the vehicle service, we need to add the credit evaluation, so as to obtain different quality of service quality. Then, the interaction between the on- board edge cloud server and the vehicle in the process of service caching is modeled as a one-to-many two-stage Stackelberg game. Based on the utility functions of both sides, the existence and uniqueness of Stackelberg equilibrium is proved by backward induction. In addition, a genetic intelligence optimization algorithm is designed to help solve the utility optimization problem.
