Reliability is described as a probability that a system will operate properly for a defined length of time without any failures, and is considered as one of the important design attributes. Safety critical devices, such as the Steer-by-Wire, should be considered as redundant E/E architectures that are configured as two identical controllers to ensure higher functionality, which is further defined as reliability that can recover from any failures. Two identically configured controllers should swap a role in the redundancy scheme within the deadline when a system detects a fault. A challenge to dynamic redundant systems is to determine a precise role in the active controller to operate a system, to detect errors in the active controller, and to take over as a backup controller in the defined time. Thi paper studies dynamic redundant architectures and arbitration control methods that can provide full fault-tolerance without any deviation in functionality even in the occurrence of faults. |
