Dynamic decision sequencing method and apparatus for optimizing a diagnostic test plan
First Claim
1. A computer-implemented method of dynamically producing a diagnostic test procedure sequence to diagnose a failure mode of a vehicle, comprising the steps of:
- selecting a first plurality of diagnostic test procedures related to a symptom exhibited by the vehicle;
arranging an order of the first plurality of diagnostic test procedures based on a probabilistic failure mode analysis and time required to perform each of the first plurality of diagnostic test procedures;
formatting a step of a first diagnostic test procedure from among the first plurality of diagnostic test procedures for display on a display device;
displaying the formatted step on the display device;
arranging an order of a second plurality of diagnostic test procedures, which includes one of the diagnostic test procedures of the first plurality of diagnostic test procedures, during execution of the first plurality of diagnostic test procedures, and based on intermediate diagnostic test information obtained from execution of the first diagnostic test procedure; and
displaying a step of a second diagnostic test procedure from among the second plurality of diagnostic test procedures on the display device,wherein each of the above steps is performed by a computer.

Abstract
A dynamic diagnostic plan generator arranges diagnostic test procedures related to a vehicle symptom or operational problem in a sequence based on a probabilistic Failure Mode and Effects Analysis (FMEA). The diagnostic plan generator also tracks a vehicle state, and provides instructions for test preparation steps and instructions for performing the diagnostic test procedures. The plan generator further generates schematic illustrations of the diagnostic test procedures, and creates a diagnostic data structure containing information related to the diagnostic test procedures. In addition, the diagnostic plan generator sends and receives information regarding actual failure mode occurrences, for example, to and from a central database. Furthermore, the diagnostic plan generator facilitates the creation of failure mode tests by an expert diagnostics author.
