Abstract—The in-vehicle bus network is the main tool for transferring data between automotive electronic control systems. This study focuses on the network security of the in-vehicle FlexRay bus network. The objective is to improve the fault information detection and fault tolerant control technology of FlexRay bus network information by using advanced technologies such as big data management and optimal guaranteed performance. For the problem of fault information detection in the data layer, an anomaly detection system of information and a message perception module based on the message perception method are proposed. We are keen to capture the horizontal and vertical correlation of FlexRay bus network information. Automatic correction of fault information through up and down message perception methods achieve the goal of fault-tolerant control. We have built the Hardware-in-the-Loop Simulation (HILS) experimental architecture using bus information from real vehicles and an automotive-specific bus network design platform. The security and operability of the proposed anomaly detection system of information and fault tolerance control scheme are verified. The experimental simulation results show that the detection accuracy of anomaly information in the vehicle FlexRay bus network reaches 99%.
