In this paper, we elaborate the architectures, operation procedures, advantages and disadvantages of the centralized as well as the distributed crowd sensing framework in IoV. On the basis of these frameworks, we proposed a novel hybrid framework which facilitates crowd sensing and service in IoV. The hybrid framework integrates the advantages in terms of sensing efficiency and information utility in centralized and distributed framework, respectively, which resolves the contradiction between the efficient and real-time sensing in IoV. The hybrid framework expands new research field for mobile crowd sensing and coordinated computing.
