Filed:

Dec 23, 2009

Appl. No.:

12/645619

Inventors:

Steven R. Krause - Chillicothe IL, US
Eric J. Dishman - Peoria IL, US
Wayne A. Lamb - Chillicothe IL, US
Erik J. Eddington - Bartonville IL, US

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

G06F 7/00

US Classification:

701 50, 701 36, 37414

Abstract:

The disclosure describes, in one aspect, an implement control system that includes a controller operatively connected to an implement. The controller is adapted to receive a signal from an input device indicative of a desired implement movement by an operator and to receive an automatically generated signal indicative of an automatically determined implement movement. The controller is further adapted to determine whether to move the implement based on the input device signal or the automatically generated signal. The controller is adapted to generate a control signal to move the implement based on the input device signal when a portion of the implement is above a desired cutting plane.

International Classification:

G06F 7/00
G01C 21/00

US Classification:

701 50, 701213

Abstract:

The disclosure describes, in one aspect, a method for determining a position on a machine relative to a reference position on the machine. The method includes determining the reference position in a coordinate system, determining a first desired position on the machine in the coordinate system, and determining the first desired position relative to the reference position. The method further includes updating a control system using the first relative desired position.

Filed:

Mar 31, 1999

Appl. No.:

09/282381

Richard J. Skiba - Peoria IL

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

G01M 1900

US Classification:

73 172

Abstract:

The present invention provides an apparatus and method for determining a status of a relief valve located within a fluid system having a pump and an actuator valve. The fluid system is located on an earth moving machine, and the pump delivers fluid to the actuator through the actuator valve. The system includes a pressure compensation assembly adapted to control the fluid pressure of the system by bypassing fluid flow. The system also includes a relief valve, and a pressure sensor. The method includes the steps of positioning the actuator valve in a closed position, deactivating the pressure compensation assembly, and sensing a relief pressure of the system.

Steven Robert Krause - Chillicothe IL, US

Assignee:

Caterpillar Inc. - Deerfield IL

International Classification:

E02F 3/84
E02F 9/20

Abstract:

A method for operating an implement of a work machine is disclosed. The method includes detecting a progression of an input device between a first position and a second position based on a first parameter and a second parameter; determining a plurality of segments of the progression; estimating a value of the second parameter of at least one first segment and at least one second segment; issuing a baseline signal to generate command to initiate manipulation of the implement if the value of the second parameter of the first segment complies with corresponding second parameter threshold condition; issuing a secondary signal to continue manipulation of the implement if the value of the second parameter of the second segment complies with corresponding second parameter threshold condition; and terminating the command if the value of the second parameter of at least one second segment violates the corresponding second parameter threshold condition.

International Classification:

E02F 5/32
E02F 9/20

Abstract:

A system and method of controlling a ripping operation is disclosed. The method includes lowering a ripper of a machine to a depth under a work surface. The method determines when a drawbar pull of the machine is at a drawbar pull target for the machine. When the drawbar pull is greater than the drawbar pull target, reducing power source torque of the machine from a first power source torque to a second power source torque.

Assignee:

CATERPILLAR INC. - Peoria IL

International Classification:

E02F 9/26

Abstract:

A controller uses a Kalman filter to develop an estimated position of an implement based on a previous implement position, an implement pitch, an implement pitch rate and an estimated implement linkage velocity. The controller moves the implement to a desired position based on the estimated position of the implement.
