Managing trust is critical for Intelligence Vehicles IVs collaboration. Forming clusters/platoons, IVs can work together to accomplish complex jobs that they are unable to perform individually. To improve safety and efficiency of collaboration, IVs' trust management has been extensively studied and a number of approaches have been proposed. However, most of these proposals either pay little attention on consensus forming among vehicles or ignore the utility of networked Road-Side-UnitsRSUs. In this paper, we introduce a cluster consensus-based trust management scheme for IVs, where some malicious or incapable vehicles are existing on roads. The proposed scheme works by allowing IVs to evaluate each other, communicate and finally converge to a consensus where some trustworthy Cluster Head CH are generated. Periodically, the CHs take responsibility for intra-cluster trust management. Moreover, the scheme is enhanced with a distributed supervising mechanism and a central reputation arbitrator. The simulation results show that our scheme can achieve a high robustness to malicious/incapable IVs by limiting failure rate below 1i¾?%.
