This article focuses on how to effectively make full use of the storage resources in vehicular cloud. A trust mechanism called DI-Trust (Trust Model Based on Dynamic Incentive Mechanism) is proposed to schedule vehicular cloud storage resource. The discussion is under the scenario of the parking lot where vehicle nodes are in static state. The model can reasonably arrange the suitable scheduling algorithm according to the attribute characteristics of different kind of service requirements. The trust value of a vehicle is updated according to the model to fully utilize the vehicle idle storage resources. The simulation experiment results show that the model can work effectively. It can objectively evaluate trust values of vehicle nodes, and construct the effective resource schedule of the vehicular cloud storage resource to meet needs from users.

本文重点介绍如何有效利用车辆云中的存储资源。提出了一种称为DI-Trust（基于动态激励机制的信任模型）的信任机制来调度车辆云存储资源。讨论是在车辆节点处于静态状态的停车场的情况下进行的。该模型可以根据不同类型服务需求的属性特征合理安排合适的调度算法。根据模型更新车辆的信任值，以充分利用车辆的闲置存储资源。仿真实验结果表明该模型可以有效地工作。它可以客观地评估车辆节点的信任值，并构造出车辆云存储资源的有效资源计划，以满足用户的需求。
