A method is provided for constructing a secret code in a processing unit when in communication with a portable security unit. Mutual authentication messages are exchanged between a linked portable security unit and processing unit. A first portion of the secret code is communicated to the processing unit. The processing unit combines the first portion and a second portion of the secret code stored in the non-volatile memory of the processing unit. The secret code is stored in a volatile memory of the processing unit. A secure operation is performed using the secret code. The portable security unit is de-linked from the processing unit. At least a portion of the secret code is deleted from the volatile memory of the processing unit.

Method and system of reconstructing a secret code in a vehicle for performing secure operations

A method is provided for enhancing service diagnostics for root cause analysis of an identified problem in a vehicle. Service repair data of previously serviced vehicles is obtained from a memory storage device. The service data is compiled based on a service repair history for each vehicle. Each vehicle within the compiled service data having at least two service repairs performed within a predetermined period of time is identified. Combinations of parts serviced during each service repair are identified. A count is determined that indicates the number of times each combination appears in the compiled service data. The combinations having counts greater than a predetermined threshold are identified. A determination is made whether any of the combinations having counts greater than the predetermined threshold are present in the structural taxonomy database. A functional taxonomy database is updated by assigning the selected combinations to the function taxonomy database not present in the structural taxonomy database.

Fusion of structural and cross-functional dependencies for root cause analysis

A method is provided for enhancing service diagnostics utilizing service repair data of previously serviced vehicles. Service repair data of previously serviced vehicles is obtained from a memory storage device. The service data is compiled into a service diagnostic code dataset and a service labor code dataset. The service diagnostic code dataset and service labor code dataset are categorized into an electronic data table. Respective combinations are formed in the electronic data table. An aggregate count is determined for each respective combination in the electronic data table. Either of a respective diagnostic code or a respective service labor code is identified having a correlation with more than one of either service diagnostic codes or service labor codes. At least one of a service repair procedure used to repair the vehicle or a respective service diagnostic code used to identify the fault is modified in response to analyzing the respective combinations.

Process for service diagnostic and service procedures enhancement

A method is provided for detecting trends in service repairs for vehicles. Service repair verbatims are accessed from a warranty database that includes information relating to an identified concern with the vehicle. A thesaurus of service repair related terms is provided. The service repair related terms are each associated with at least one of a component category, a concern category, a cause category, and a correction of repair category. Key terms are identified in each service repair verbatim that have an association with the service repair related terms in the thesaurus. The key terms are extracted from each of the service repair verbatims. A user selectively generates a report based on a key term in the component category and at least one other key term from at least one other category. The report identifies an aggregate number of service repair verbatims associated with the key terms selected by the user.

Text extraction for determining emerging issues in vehicle warranty reporting

An integrated diagnosis and prognosis system that collects vehicle information over the life of a vehicle and its development. The system provides the collected vehicle information to supplier management, product development management, service/dealership management, customer relations departments and production facilities, which use the information to take certain action for existing vehicles, fleets of vehicles or future vehicles to improve vehicle reliability and quality.

Integrated diagnosis and prognosis system as part of the corporate value chain

A method for generating a manufacturing process map comprises obtaining sets of N-dimensional expert data from at least three sources, defining a membership function for each set of expert data, applying fuzzy logic operations to said membership functions to generate new membership functions, the new membership functions defining N-dimensional regions within an N-dimensional design space and using one of said N-dimensional regions to generate the manufacturing process map.
