摘要
An apparatus and method for diagnosing an engine using computer based models in combination with a neural network which reduces the neural network training and updating required is disclosed. The method and apparatus determine modeled values for a plurality of engine parameters as a function of sensed values in a plurality of initial values; sense a plurality of actual values for the engine parameters; and determine a difference between the actual values and the modeled values for the respective engine parameters. The differences are inputted into a neural network which generates an output pattern as a function of the differences and a plurality of weight values. The weight values and the initial values are then updated as a function of a comparison between the output patterns and a desired pattern, and the engine is responsively diagnosed as a function of the output pattern.
