Abstract:
1. A method of controlling a fill event of an apply chamber of a fluid-actuated clutch, the method comprising: determining a plurality of input values describing the fill event, including a calibrated command line pressure, a calibrated command fill stroke pressure, and a viscosity of a fluid used for filling the apply chamber, wherein the plurality of input values collectively defines a clutch fill signature (CFS); processing the plurality of input values using a neural network having an input layer, a hidden layer, and an output layer each with one or more nodes to thereby recognize a pattern of the CFS; estimating a fill time required for filling the apply chamber with the fluid using the pattern that is recognized by the neural network; and filling the apply chamber with the fluid using the estimated fill time (EFT) to thereby optimize the fill event.
