Regulation parameter evaluation method for friction clutch in automobile drive transmission determines base regulation parameter value at which hydraulic fluid is supplied to clutch operating element

摘要

The parameter evaluation method uses an initial procedure for determining a base value for the regulation parameter, at which the control valve (20) in the hydraulic clutch operating system (10), controlled by the regulation parameter, provides a fluid flow to the clutch operating element (22), e.g. by determining the mean value between 2 measured control values, corresponding to clutch oscillation relative to a defned clutch position. An Independent claim for a regulation device for hydraulic friction clutch engagement and disengagement is also included.
