Appl. No.:

10/028665

Inventors:

Thomas G. Skinner - Aurora IL

Assignee:

Caterpillar Inc - Peoria IL

International Classification:

F15B 909

US Classification:

91363R, 91361, 91364

Abstract:

A method for controlling a fluid system is provided. The system may include a hydraulic circuit having a pump driven by an engine, wherein the pump delivers fluid to an actuator through a valve assembly. The method may include receiving an operator input and determining a condition of the hydraulic circuit. The condition of the hydraulic circuit may include at least one of a flow rate of fluid to the actuator, an engine speed, and a pump displacement. The method may include determining a valve transform function as a function of a position of a linkage associated with the actuator and the condition of the hydraulic circuit. The method may further include determining a valve command in response to the valve transform function and the operator input, wherein the valve command results in a consistent deadband. The valve command is delivered to the valve assembly.

Appl. No.:

09/885254

Inventors:

Hans P. Dietz - Naperville IL, US
Thomas G. Skinner - Aurora IL, US

Assignee:

Caterpillar, Inc. - Peoria IL

International Classification:

G05D001/02
G05D001/04
E02F005/02

US Classification:

37348, 37348, 37414, 37382, 701 50, 91361

Abstract:

An apparatus for controllably positioning a work implement of an earth moving machine is disclosed. The work implement includes a boom and an attachment being attached thereto where the boom is actuated by a hydraulic lift cylinder and the attachment is actuated by a hydraulic tilt cylinder. Implement position sensors sense the elevational position of the boom and the pivotal position of the attachment and responsively produce respective implement position signals. A controller that receives the implement position signals, compares the relative position of the boom and the attachment with a pre-determined boundary condition, and produces an electrical valve signal. A valve assembly receives the electrical valve signal and controllably provides hydraulic fluid flow to the respective hydraulic cylinders in response to a magnitude of the electrical valve signal.

Appl. No.:

11/017044

Inventors:

Thomas G. Skinner - Bolingbrook IL, US

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

G08C 21/00
G06F 17/00

US Classification:

702150, 702152, 3406861

Abstract:

A programmable position sensing system for monitoring a position of a monitored component movable between a first position and a second position includes a housing associated with the monitored component and a sensor associated with the housing and disposed onboard the monitored component. The sensor is configured to monitor a position of the monitored component. A memory component is associated with the housing and disposed onboard the monitored component.

Filed:

Jul 7, 2003

Appl. No.:

10/614526

Inventors:

Arun Hamasagar - Plainfield IL, US
Thomas Skinner - Bolingbrook IL, US

International Classification:

G01P003/36

US Classification:

324175000

Abstract:

A position sensor assembly adapted to mount externally to a linkage system may comprise first and second sensor housing members and first and second sensor portions. The first housing member may be adapted for external connection to the linkage system, may have a first sensor conduit therein, and may be configured and arranged to at least partially enclose the first and second sensor portions. The second sensor housing member may be slidably received within the first sensor housing member and may have a second sensor conduit therein. The first sensor portion may be connected with the first sensor housing member, and the second sensor portion may be connected with the second sensor housing member. The position sensor assembly may be operable to register a position of the first sensor portion relative to the second sensor portion as a result of cooperation between the first and second sensor portions.

Filed:

Mar 29, 1999

Appl. No.:

9/280914

Inventors:

Hans P. Dietz - Naperville IL

Thomas G. Skinner - Aurora IL

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

A01B 6700

US Classification:

172 3

Abstract:

An apparatus for controlling the torque associated with a power train of a machine having a work implement is disclosed. A plurality of position sensors sense the position associated with the work implement and responsively produce respective position signals. A controller modifies the desired engine speed in response to the angular position of the work implement and regulates the speed of the engine at the modified desired engine speed to control the power train torque.

US Patent:

Filed:

Mar 12, 1999

Appl. No.:

9/267542

Inventors:

Thomas G. Skinner - Aurora IL
Hans P. Dietz - Naperville IL

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

F15B 1316

US Classification:

701 50

Abstract:

An apparatus for controllably moving a work implement of an earth moving machine is disclosed. The work implement includes a boom and a bucket being attached thereto where the boom is actuated by a hydraulic lift cylinder and the bucket is actuated by a hydraulic tilt cylinder. An operator controlled joystick produces an operator command signal for controlling the movement of the work implement. Implement position sensors sense the elevational position of the boom and the pivotal position of the bucket, and responsively produce respective implement position signals. A controller receives the implement position and operator command signals, determines the instant position of the work implement, reduces the operator command signal as the boom is being raised and the bucket is being pivoted, and produces an electrical valve signal based on the reduced operator command signal. A valve assembly receives the electrical valve signal and controllably provides hydraulic fluid flow to the respective hydraulic cylinders in response to a magnitude of the electrical valve signal.
