Abstract
Automotive electronics can be divided into subsystems according to their functions and physical locations Employing this concept, a hierarchical architecture of automotive electronics may be evolved In this paper a hierarchical fault tolerant distributed processing system has been introduced The system consists of a central controller (CC), m subsystems, a main bus and a shared memory module Each subsystem consists of n processors, one smart sensor group and one smart actuator group The central controller maintains the performance history of every processor in system In case of a processor's failure, the CC assigns the tasks of the faulty processor to another processor within the same subsystem
Reliability, which is the probability of a correctly working system for an interval of time [t-t0], has been evaluated An algorithmic approach based on the truth table method has been developed for evaluating the reliability of the proposed hierarchical architecture A comparison of the reliability calculation has been done between the proposed architecture and a system without fault tolerance capability The results show that the proposed architecture provides better reliability
