Patent number: 7753132Abstract: A method of controlling a machine during an excavating operation is provided. Stabilizers are deployed to ground contact to stabilize the machine at a first set-up position. Excavating is performed with an excavating assemblage during a first excavating phase while the machine is stabilized at the first set-up position. An automated machine preparation for repositioning mode is initiated for preparing the machine, after the excavating phase, for repositioning to a second set-up position for a second excavating phase, by activating an input device to send input signals to a controller. Output signals are delivered from the controller to control automated machine preparation for repositioning to the second set-up position.Type: GrantFiled: November 30, 2006Date of Patent: July 13, 2010Assignee: Caterpillar IncInventors: Daniel Stanek, Roger D.

Patent number: 7726048Abstract: A method of repositioning a machine during an excavating operation from a first machine position to a second machine position is provided. A target distance to the second machine position is selected. An operator input device configured to send a control input signal to a control module to initiate a repositioning phase is activated. During a repositioning phase, the machine is moved toward the second position while an operator maintains control of movement. A determination is made when the machine has traveled the target distance. The machine is stopped under automated machine control at the second machine position.Type: GrantFiled: November 30, 2006Date of Patent: June 1, 2010Assignee: Caterpillar Inc.Inventors: Daniel Stanek, Roger D.

Patent number: 7634863Abstract: A method is provided for enhancing the repositioning of an excavating machine, including an excavating assemblage, from one set-up position to a next, subsequent set-up position. A joystick is controlled in implement control mode to operate at least one of a boom, a stick, and a bucket of the excavating assemblage during a first excavating phase from a first machine set-up position. The first excavating phase is terminated and, during a machine repositioning phase, the machine is moved to a second machine set-up position for a second excavating phase at the second machine set-up position. After terminating the first excavating phase and before moving the machine to the second machine set-up position, an input/display device is accessed and activated to convert the joystick from implement control mode to machine control mode. At least machine steering and machine propulsion are controlled with the joystick set in the machine control mode during the machine repositioning phase.Type: GrantFiled: November 30, 2006Date of Patent: December 22, 2009Assignee: Caterpillar Inc.Inventors: Daniel Stanek, Roger D.
