英文摘要： The project focuses on the integrated X-by-wire system combined steer and brake function,the software replication strategy is applied into agent-based intelligent control, agent replication group with redundant features is devised. Focusing on fault tolerance of unit system and reconstruction of integrated system, with the loosly coupled intelligence of multi-Agent replication group, a fault-tolerant control method for integrated X-by-wire system with an open architecture is developed. The generalized description of the agent replication group is established, and the communication mechanism and the coordination rules for the multi-agent replication group is investigated. Based on the analysis of the fault type and characteristics of the integrated X-by-wire system, the fault detection and diagnosis algorithm is designed, and the system is optimized using hierarchical modular design method. The ability of system fault tolerance is improved by intelligent system response, and the open architecture enhances the feasibility of practical application. In this project, the basic fault-tolerant control architecture for the integrated X-by-wire system combined steer and brake function is constructed based on distributed intelligence. The hardware platform and software environment are propsed. The fault-tolerant control m
