US Patent:
6647332, Nov 11, 2003
Filed:
Dec 21, 1998
Appl. No.:
09/219503

International Classification:
G06F 1700
US Classification:
701 51, 701 67, 701 68, 192 358, 192 357, 192 354, 192 586, 192 5863, 192 32, 477 76
Abstract:
The present invention provides a method and apparatus for controlling the pressure of an actuating fluid flowing through an inching clutch. The invention includes the steps of determining an actual pressure of the actuating fluid, establishing an inching pressure threshold, comparing the actual pressure with the threshold, and controlling the actual pressure in response to the comparison. In one embodiment, the pressure is controlled using a first control algorithm in response to the fluid pressure being less than an inching threshold, and using a second control algorithm in response to the pressure being greater than or equal to the inching threshold.

Abstract:
A drive line assembly for a work machine is disclosed. The drive line assembly includes an engine driving an engine output shaft and an engine speed sensor which generates engine speed signals indicative of a speed of the engine output shaft. The drive line assembly further includes a fuel injector operable to regulate fuel flow to the engine and a transmission driven by the engine output shaft and having a first on-coming clutch. The drive line assembly yet further includes a controller operable to determine the engine speed from the engine speed signals and determine the fuel flow through the fuel injector. The controller is further operable to determine an engine load based on the fuel flow and a predetermined maximum fuel flow for the engine at the engine speed and control engagement of the first on-coming clutch based on the engine load. A method for controlling a drive line assembly is also disclosed.
