Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

A01B 7900

US Classification:

172 1

Abstract:

A method for automatically rotating a motor grader to a predetermined articulation angle. The method includes the steps of: providing an electronic controller, a displacement sensor, articulation cylinders, and an input switch; obtaining information from the displacement sensor indicating the present articulation angle of the motor grader; receiving an input signal from the input switch requesting a predetermined articulation angle; and producing a control signal for actuating the articulation cylinders to rotate the motor grader from the present articulation angle to the predetermined articulation angle.

Abstract:

A method for determining a series of work cycles for an earthmoving machine is disclosed. The method includes the steps of determining a plurality of parameters, modeling a volume of material to be moved, planning a series of work cycles to move the volume of material, and determining a level of productivity of the series of work cycles. The method also includes the steps of repeating the above steps a predetermined number of times and choosing an optimal series of work cycles to move the volume of material.

Daniel E. Shearer - Metamora IL

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

G08B 2100

US Classification:

3406866

Abstract:

A system and method for monitoring the position of a motor grader blade relative to a motor grader frame. The method includes the steps of: providing an electronic controller, blade controls having position sensors, and frame controls having position sensors; monitoring the output of the position sensors to ascertain the position of the blade controls and the frame controls; receiving an input signal requesting a repositioning of the blade or the frame; determining the present blade position and the present frame position; calculating a future blade position and a future frame position based on the repositioning request; predicting an intersection of the future blade position and the future frame position; and producing an action to prevent the intersection of the future blade position and the future frame position.

International Classification:

G06F 1900
E02F 300

US Classification:

702105

Abstract:

A system and method for automatically adjusting the blade of a motor grader to an operator programmed blade position. The method includes the steps of: providing an electronic controller and blade controls having position sensors; monitoring the output of the position sensors to ascertain the position of the blade controls; receiving a first input signal for setting a memory blade position; determining the memory blade position based on the output of the position sensors; receiving a second input signal for requesting the memory blade position; determining the present blade position based on the output of the position sensors; and producing a control signal for actuating the blade controls to move the blade from the present blade position to the memory blade position.

Appl. No.:

14/633172

Inventors:

- Peoria IL, US
Matthew A. Hartman - Bloomington IL, US
Michael C. Gentle - Maroa IL, US

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

B60Q 9/00

Abstract:

A method of notifying an operator that a reductant tank associated with a machine is in a full state during filling of the reductant tank. The method includes receiving a signal indicative of a current level of the reductant within the reductant tank from an electronic control module of the machine. The method also includes comparing the current level of the reductant with a predetermined threshold. The method further includes determining if a full tank status of the reductant tank exists corresponding to the current level of the reductant being greater than the predetermined threshold. The method further includes triggering a notification based on the determination of the full tank status condition of the reductant tank. The notification is provided in such a manner to alert an operator positioned outside of the machine of the full tank status of the reductant tank.
