摘要： A vehicle analysis system includes a system analyzer, such as an engine analyzer, having probes that gather data from vehicle parameters such as engine components. The data is converted into digital signals, which are processed into display data and stored in a computer memory. A controller converts the display data into packets that may be transmitted across a communications network to a remote computer using transmission control protocol/Internet protocol.

摘要： A data driven, multi-dimensional diagnostic method that combines vehicle system test data, vehicle attributes, symptoms, and extrinsic data to produce vehicle system diagnostics. Data are combined according to predetermined equations to yield intermediate diagnostic results. Intermediate diagnostic results are combined recursively according to fixed expressions to produce final diagnostic results relating to the state of the vehicle system under diagnosis. Fixed expressions may be algebraic, Boolean, fuzzy logic, statistical, or relate to an expert system.
