Apparatus and method for analyzing multiple fault occurrence of multiple-state device
First Claim
1. An apparatus for facilitating analysis of a multiple-state device responsive to multiple fault occurrence, said apparatus comprising:
- an identifier module in an electronic control device configured to automatically identify, during operation of the multiple-state device and in response to an occurrence of multiple detected faults in said multiple state device, a plurality of automatic remediation actions available to the multiple state device for states of the multiple-state device and fault occurrences possible at the states; and
a hazard scorer module in said electronic control device configured to automatically provide a representation of a hazard level associated with each available remediation action,in which a hazard level represents an indicia of potential deleterious results that may occur due to operation of the multiple-state device in a state defined by the remediation action.

Abstract
Apparatus, and an associated method, for analyzing operation of a multiple-state device, such as a vehicular automatic transmission under multiple-fault occurrence. An identifier identifies all possible path sequences of an initial state responsive to occurrence of all possible faults and all possible remediation actions. The paths are identified for a multiple-fault occurrence of two or more faults. For each of the possible paths, a hazard level is assigned, and the hazard levels are sorted to obtain preferred path sequences. Analysis of the possible paths and their associated hazard levels is made, and a state control scheme is formulated.

13. A method for facilitating analysis of a multiple-state device responsive to multiple fault occurrence, said method comprising:
-
responsive to an occurrence of multiple detected faults in said multiple state device and during operation of the multiple-state device, identifying with an electronic control device a plurality of automatic remediation actions available to the multiple state device for states of the multiple-state device and fault occurrences at the states; and automatically providing a representation of a hazard level associated with each available remediation action with said electronic control device, in which a hazard level represents an indicia of potential deleterious results that may occur due to operation of the multi-state device in a state defined by the remediation action, and in which the remediation action taken is a change in a current operation of an apparatus operated by the multiple-state device. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. An electronic multiple failure mode analyzer for analyzing a multiple-state, vehicular transmission under a multiple fault condition, said analyzer comprising:
electronic processing circuitry implementing; a modeler configured to model, for each state of the multiple-state vehicular transmission, every possible multiple fault condition and available remediation action responsive thereto; a hazard level assignor configured to assign a hazard level for each possible multiple fault condition and available remediation action responsive thereto; a hazard scorer to; compare a value identifying a hazard associated with the available remediation action and a value identifying a hazard associated with an erroneous undertaking; and select the representation of the hazard level responsive to comparisons made during said comparing, in which a hazard level represents an indicia of potential deleterious results that may occur due to operation of the multi-state device in a state defined by the remediation action, and in which the remediation action taken is a change in the operation of an apparatus operated by the multiple-state device.
