“…A cold standby dynamic redundancy system uses only one module at a time, and the reconfiguration module controls two switches to block the signal from the faulty module. By combining the two approaches, a hybrid redundancy system using techniques such as self-purging redundancy [18] or a smoothing voter [19] can mask a fault just like the static approach, but it can also detect a fault and reconfigure the system just like the dynamic approach using a switch and a fault-detection algorithm [20][21].…”

Safety issues and the dependence of numerous systems on electronics are rapidly increasing the concern over fault tolerance. As an example, an intelligent vehicle with electronically controlled x-by-wire systems composed of dynamically configurable electronic elements instead of rigid mechanical components must be fault tolerant because a devastating failure could occur without warning. In particular, a safety-related malfunction of the brakes, throttle, or steering system could lead to serious injury or death and damage the manufacturer's reputation. If there is a warning it may not be as devastating as one could prevent it or mitigate it. Therefore, fault tolerance is the primary focus of x-by-wire systems development. To address this concern, this paper presents a fuzzy predictive redundancy system that can remove most erroneous faults with a fault detection algorithm. This paper also introduces a prototype of the system using an embedded microcontroller unit. The experimental results show that fuzzy predictive redundancy can be an appropriate choice for fault tolerance in the x-by-wire systems such as steer-by-wire system or brake-by-wire system of intelligent vehicle.

“…However, the system presented is of limited use because only single module failures per clock cycle are allowed. A solution which can tolerate multiple module failures at any time is presented in [4], but no solution to build the voter is presented. In this paper a very efficient decomposition technique for the logic function performed by the voter is developed, allowing an extremely compact realization.…”
