Patent number: 10174479Abstract: An implement system for a machine includes a primary blade and a secondary blade coupled to the primary blade through a linkage mechanism such that the secondary blade is trailing the primary blade. The implement system includes an actuator which controls a movement of the secondary blade. The implement system includes at least one position sensor which generates signals indicative of a position of the primary blade and a position of the secondary blade. The implement system further includes a controller which is in communication with the primary blade, the secondary blade and the position sensor. The controller receives the signals indicative of the position of the primary blade and the position of the secondary blade. The controller operates the actuator to control the movement of the secondary blade based on the position of the primary blade and secondary blade.Type: GrantFiled: December 13, 2016Date of Patent: January 8, 2019Assignee: Caterpillar Inc.Inventor: Biagio Ciarla

Publication number: 20170190325Abstract: The present disclosure relates to a braking system and, more particularly, to a braking system for engaging a brake mechanism as a waiting brake for a load carrying vehicle. The braking system comprises first and second brake mechanisms. A controller is configured to control the operation of the second brake mechanism such that, if a predetermined fault condition is determined whilst the first brake mechanism is engaged, the controller automatically engages the second brake mechanism.Type: ApplicationFiled: April 9, 2015Publication date: July 6, 2017Applicant: Caterpillar SARLInventors: Adam Adeeb, David Richard Wisley, Samue Alec Roberts, Andrew Colin Ellis, John D. Gates, Joel Lee Skalet, Biagio Ciarla

Patent number: 9358966Abstract: A system and method for detecting a pre-charge pressure of a hydraulic braking system are disclosed. A controller receives pressure readings from a pressure sensor indicative of the pressure of a hydraulic brake accumulator or the lower pressure of more than one accumulator. In response to fluid being provided to the hydraulic accumulator, the controller determines a first rate of pressure change, a second rate of pressure change different than the first rate, and a transition pressure between the first and second rates. The controller determines an approximate pre-charge pressure of the hydraulic brake accumulator based on the transition pressure. A warning can be provided to the operator or another when the determined pre-charge pressure is lower than a reference pressure.Type: GrantFiled: September 29, 2014Date of Patent: June 7, 2016Assignee: Caterpillar SARLInventors: Stephen Thompson, Peter O'Brien, Biagio Ciarla, Adam J. Adeeb

Patent number: 9266513Abstract: A system and method are provided for enhancing the slope-holding capability of an earth-moving machine. The machine includes a plurality of ground-engaging elements and a first parking brake configured to brake a first subset of the plurality of ground-engaging elements. A second parking brake is mounted and is configured to brake a second subset of the plurality of ground-engaging elements. A brake controller is configured to sense engagement of the first parking brake and to engage the second parking brake when the first parking brake is engaged only if one or more machine state criteria are also met. In an embodiment, the one or more machine state criteria include zero machine speed, neutral transmission state, and a machine slope that exceeds a predetermined threshold slope.Type: GrantFiled: March 21, 2014Date of Patent: February 23, 2016Assignee: Caterpillar Inc.Inventors: John Gates, Biagio Ciarla, Josh Nolke, Nasim Suterwala, Andrew Ellis, Neil Taylor, Ian R A Hawkes

Publication number: 20150323069Abstract: The present disclosure relates to a method of disengaging a brake mechanism used as a waiting brake for a load carrying vehicle. In a vehicle comprising an automatic transmission system having at least one drive mode and a neutral mode, changing the mode of the transmission system from neutral mode to a drive mode automatically disengages the brake mechanism.Type: ApplicationFiled: May 9, 2014Publication date: November 12, 2015Applicant: Caterpillar SARLInventors: Neil Taylor, Adam Adeeb, David Richard Wisley, Jonathan Trawford, Samuel Alec Roberts, Andrew Colin Ellis, John D.

Publication number: 20150198507Abstract: A method of determining readiness of an emergency steering pump system is provided. The method may include the steps of detecting a startup condition; determining a standby pressure provided by a primary pump and a margin pressure to be provided by a secondary pump; engaging the secondary pump for a predefined duration based on the standby pressure and the margin pressure; and determining readiness based on a cumulative pressure of the standby pressure and the margin pressure as compared to a predefined threshold corresponding to load demand.Type: ApplicationFiled: January 15, 2014Publication date: July 16, 2015Applicant: Caterpillar, Inc.Inventors: David Arthur Mork, Biagio Ciarla, Wendell Dean Stahl, Daniel Todd Mather

Publication number: 20130173190Abstract: A method of operating a power system with an electrical energy-storage device is disclosed. The method may include estimating with at least one information-processing device a present charge capacity of the electrical energy-storage device. This may include determining an estimated fatigue-adjusted discharge value by determining an estimated amount of electrical energy discharged from the electrical energy-storage device and applying a fatigue factor to the estimated amount of electrical energy discharged. The fatigue factor may be determined based on a magnitude of electricity discharged from the electrical energy-storage device. The method may also include estimating the present charge capacity of the electrical energy-storage device based on the estimated fatigue-adjusted discharge value and an estimated full capacity of the electrical energy-storage device.Type: ApplicationFiled: December 30, 2011Publication date: July 4, 2013Inventors: Dachuan Yu, Biagio Ciarla, Justin Dale Middleton
