摘要:
A system and method for improving diagnostic aids such as fault trees and repair manuals uses feedback in the form of repair data from a distributed base of data collection devices used by technicians. The data is processed by a data analysis computing unit. The computing unit determines proposed modifications to the diagnostic aid based on the data. A diagnostic tool editor is used by a subject matter expert to review the proposed modifications and either accept, reject, or modify the diagnostic aid. The modified aids are then made available to the service technicians in the field, improving their efficiency and ability to more quickly diagnose machine conditions. The disclosure is applicable to machines generally, including for example automobiles or components thereof, such as engines and transmissions.
摘要:
A method is provided for updating a fault tree used in diagnosis of a condition of a machine. The fault tree is a sequence of test modules. Each of the test modules is assigned a confidence score indicating the likelihood that the test module will lead to a diagnosis. The method comprising the steps of obtaining service data from a plurality of service occasions for like machines, revising the confidence score for at least one test module in the fault tree based on the service data; and revising the sequence of the test modules in the fault tree based on the revised confidence score(s). The sequence is revised such that the most likely modules to result in a diagnosis are listed first, and the least likely ones are listed last. The re-ordering is based on feedback from actual service instances in the field, and thus is more likely to reflect real-world conditions. The result is that service technicians using the revised fault trees work more efficiently, at least on a statistical basis.
摘要:
A system and method for diagnosing an assembly is provided. The system and method facilitates assembly diagnosis by (i) sensing sensory-inputs coming from the assembly, (ii) capturing data representative of the sensory-inputs and responsively producing sensor patterns indicative of the sensory-inputs, (iii) searching a data base of historical patterns that are related to the sensor patterns, and (iv) presenting the sensor patterns and related historical patterns at a user interface. An assembly diagnosis can be made based on sensor patterns, related historical patterns, and other diagnostic information presented at the user interface.
摘要:
A vehicle diagnostic system including a processor, a user interface including a display device and an input device both coupled to the processor for interactive control thereof and thereby, and a local storage library connected to the processor for storing at least one application to be performed on a vehicle. The processor is programmed to request vehicle identification information from a user through the display device, create a particular configuration identifier containing the vehicle identification information entered by the user through the input device, store the particular configuration identifier in the local storage library, retrieve at least one application from the library as the application is selected by the user through the input device, and provide the particular configuration identifier to the application.
摘要:
A vehicle diagnostic system comprising a rules storage system configured to store one or more rules, each of which determines whether the vehicle may have an anomaly when applied to vehicle diagnostic information. An operator interface may be configured to alert an operator of the diagnostic system to a suspected anomaly in the vehicle. A processing system may be configured to receive diagnostic information from the vehicle, apply one or more rules in the rules storage system to the diagnostic information, and cause the operator interface to alert the operator to a suspected anomaly in the vehicle if the application of the one or more rules results in a determination that the vehicle may have that anomaly. Variations and related processes are also disclosed.
摘要:
A heads-up system includes a diagnostic tool and a heads-up display for displaying information from a vehicle. The diagnostic tool connects to a communication bus of the vehicle. The display includes a projection device and an input module that is connected to the diagnostic tool either wirelessly or with a wire connection. The input module may translate signals from the diagnostic tool into signals readable by the projection device.
