Method of shifting gears in a work machine

A method of shifting gears in a work machine (10) includes modulating an oncoming clutch pressure via a first segment of a predetermined curve, and modulating the clutch pressure via a second segment of the predetermined curve after the occurrence of a predetermined relative velocity state of a work...

Zusammenfassung:	A method of shifting gears in a work machine (10) includes modulating an oncoming clutch pressure via a first segment of a predetermined curve, and modulating the clutch pressure via a second segment of the predetermined curve after the occurrence of a predetermined relative velocity state of a work machine transmission (30). A work machine (10) having an electronic controller (20) with embedded shifting control algorithm that includes means for modulating the oncoming clutch pressure via a first segment of a predetermined curve, and via a second segment of a predetermined curve having a net slope different from the first segment after the occurrence of a predetermined relative velocity state of the work machine transmission (30).
