Multiple algorithm event discrimination method
First Claim
1. A method of discriminating an occurrence of a specified event in a system based on measured or estimated system parameter data pertinent to said event, the method comprising the steps of:
- developing a plurality of different calibrations for one event discrimination algorithm for detecting said different patterns of parameter data that are characteristic of the occurrence of said specified event;
successively executing said one event discrimination algorithm with said different calibrations to produce a plurality of event discrimination outputs; and
combining said plurality of event discrimination outputs to form a single output that discriminates the occurrence of said specified event.

Abstract
An event discrimination methodology executes multiple versions of the same or different event discrimination algorithms and logically or arithmetically combines their outputs to distinguish between specified events and non-events. One given algorithm is repeatedly executed with different sets of calibration data, or alternately, a number of different algorithms are executed. In cases where the algorithm results are arithmetically combined, the weights accorded to each algorithm result are dynamically adjusted based on driver input or vehicle dynamic behavior data to accord highest weight to the algorithm(s) calibrated to identify events associated with the detected driver input or vehicle dynamic behavior.

3. A method of discriminating an occurrence of a specified event in a system based on measured or estimated system parameter data pertinent to said event, the method comprising the steps of:
-
executing a number of event discrimination algorithms individually calibrated to detect different patterns of parameter data that are characteristic of the occurrence of said specified event, each algorithm producing an event discrimination output; applying calibrated weights to each of said event discrimination outputs; combining the weighted event discrimination outputs to form a combined output; and forming a single output based on said combined output. - View Dependent Claims (4, 5, 6, 7)
