Abstract
As intelligent vehicles have been continuously developed through technology convergence, and their level of safety or convenience has been considerably improved, the ratio of electronic sub-assembly has increased, and the number of ECU has also increased. Moreover, the importance of safety has increased, and higher reliability and availability are needed in the system. This paper intends to suggest fault-tolerant dual system for enhancing availability and reliability of vehicle safety system by using redundancy system, and to develop application for operating and managing the system.. This system using hot-standby sparing technique similar to FT-SPARC structure is composed of master and slave processor modules, and is distinctive in that only one module plays a role of master according to the operation state of system, that is, normal or abnormal operation state.
