Systems and methods for capturing and analyzing significant parameter data from vehicle systems whenever a diagnostic trouble code (DTC) is triggered. A multi-dimensional matrix is constructed, with vehicles, DTCs, and parameter data comprising three dimensions of the matrix. The data matrix is populated with DTC and parameter data from many different vehicles, either when vehicles are taken to a dealer for service, or via wireless data download. Time can be added as a fourth dimension of the matrix, providing an indication of whether a particular system or component is temporally degrading. When sufficient data is accumulated, the data matrix is pre-processed, features are extracted from the data, and the features are classified, using a variety of mathematical techniques. Trained classifiers are then used to diagnose the root cause of any particular fault signal, and also to provide a prognosis of system health and remaining useful life.

In an automotive system (300), a knock detection scheme is provided for detecting knock events in an internal combustion engine that are sensed by a transducer structure, such as a non-intrusive acoustic accelerometer sensor (310) to generate sensor signal information which is processed by a signal processing structure (312, 316, 318, 326) which extracts digital signal parameters from the sensor signal information to identify a predetermined pitch frequency (330) and any short-term energy increase (328) in the digital signal information which in combination are used to provide a positive indication of engine knock behavior. When a short term Fourier transform (324) is used to extract the digital signal parameters, time frequency resolution may be improved by appropriately windowing the digital signal being transformed.

Typically, changes in timbre in an audio reproduction system use analogue or digital filters, either shelving filters (as in the case of bass, treble and loudness controllers) and/or peaking filters (as in the case of speed-and noise-compensation in automotive systems). A problem associated with this implementation lies in the audibility of the phase shift caused by these filters. According to the invention, this and further problems are solved by utilising the crossover network of the system itself—with level adjustable output signals—to attain desired timbre and/or dynamic range adjustments and hence avoiding undesirable phase effects of the traditional bass and treble control filters. An input signal (18) is according to an embodiment of the invention divided by a cross over network (20) into a number of frequency bands and applied via level control means (21, 22, 23) and separate power amplifiers (24, 25, 26) to loudspeaker drivers (27, 28, 29). In this manner, the mentioned phase shifts can be avoided and by proper control of the level adjustment means by a frequency-dependent analysis and weighting network (30), desired adjustment of timbre and dynamic range of the audio reproduction can be achieved. Also control dependent on vehicle speed and/or background noise can be incorporated into the system..
