Patent number: 8567551Abstract: A work machine (10) comprises an operator input device (28), an electro-hydraulic system (64), and a controller unit (46) that communicates with the operator input device (28) and the electro-hydraulic system (64). The controller unit (46) is programmed to operate the electro-hydraulic system (64) in a manual-control mode and an auto-control mode, and is adapted to activate the auto-control mode in response to displacement of the operator input device (28) to an activate-auto position relative to a neutral position (42) of the operator input device (28), and both deactivate the auto-control mode and activate the manual-control mode in response to displacement of the operator input device (28) from the neutral position through a non-responsive deadband (72) about the neutral position (42) to an activate-manual position. An associated method is disclosed.Type: GrantFiled: June 15, 2007Date of Patent: October 29, 2013Assignee: Deere & CompanyInventor: Boris Trifunovic

Patent number: 8500387Abstract: A backhoe loader 10 with a controller 100 that uses angular signals from at least one sensor to calculate a loader tool angle with respect to the vehicle frame 12 or with respect to the earth and to maintain the loader tool angle via controller generated commands to a tool actuator 61 as a function of the angular signals and commands to a boom actuator 50. The controller 100 enables proportional control of the tool angle via a command input device such as an electronic joystick 21. If the electronic joystick 21 is moved to an appropriate detent position, the controller executes a return to carry function. If the boom 31 is at or below the return to carry angle at the time the joystick 21 is moved to the detent position, the controller 100 executes a float function allowing the bucket 36 and the boom 31 to rest on the ground and follow the contours of the earth as the vehicle moves over the earth.Type: GrantFiled: June 22, 2007Date of Patent: August 6, 2013Assignee: Deere & CompanyInventor: Boris Trifunovic

Publication number: 20100254793Abstract: A backhoe loader 10 with a controller 100 that uses angular signals from at least one sensor to calculate a loader tool angle with respect to the vehicle frame 12 or with respect to the earth and to maintain the loader bucket angle via controller generated commands to a bucket actuator 60 as a function of the angular signals and commands to a boom actuator 60. The controller 100 enables proportional control of the tool angle via a command input device such as an electronic joystick 21. The controller 100 is capable of maintaining an inclination of the tool 36 with respect to the frame 12. If the boom 31 rises to an angle that is equal to or above a predetermined anti-spill boom angle the controller 100 drives the tool via commands to the tool actuator 60 to a tool angle that is equal to or less than a predetermined anti-spill bucket angle.Type: ApplicationFiled: June 22, 2007Publication date: October 7, 2010Inventor: Boris Trifunovic
