Abstract
In one aspect of this invention, a fluid actuated clutch is disclosed. The fluid actuated clutch is operatively connected to a control valve that is activated by an electronic controller that receives a signal from an input mechanism. The system and method includes detecting an instantaneous clutch slip and detecting when the instantaneous clutch slip is less than an average of a predetermined number of cycles of instantaneous clutch slip that is divided by a predetermined factor. This condition represents the end-of-fill point for the fluid actuated clutch.
