Patent number: 11634885Abstract: In embodiments, a work vehicle magnetorheological fluid (MRF) joystick system includes a joystick device, an MRF joystick resistance mechanism, and a controller architecture. The joystick device includes, in turn, a base housing, a joystick movably mounted to the base housing, and a joystick position sensor configured to monitor movement of the joystick relative to the base housing. The MRF joystick resistance mechanism is controllable to vary a first joystick stiffness resisting movement of the joystick relative to the base housing in at least one degree of freedom. The controller architecture is configured to: (i) detect when unintended joystick motion conditions occur during operation of the work vehicle; and (ii) when detecting unintended joystick motion conditions, command the MRF joystick resistance mechanism to increase the first joystick stiffness in a manner reducing susceptibility of the joystick device to unintended joystick motions.Type: GrantFiled: May 1, 2020Date of Patent: April 25, 2023Assignee: DEERE & COMPANYInventors: Todd F. Velde, Alex R. Vandegrift, Craig Christofferson, Christopher J. Meyer, Aaron R. Kenkel, Mark D. Anderson, Lance R. Sherlock, Kenneth Franck

Work vehicle magnetorheological fluid joystick systems operable in modified joystick stiffness modes
Patent number: 11499294Abstract: Embodiments of a work vehicle magnetorheological fluid (MRF) joystick system include a joystick device having a base housing, a joystick movably mounted to the base housing, and a joystick position sensor configured to monitor joystick movement. An MRF joystick resistance mechanism is controllable to vary a joystick stiffness resisting movement of the joystick relative to the base housing, while a controller architecture is coupled to the joystick position sensor and to the MRF joystick resistance mechanism. The controller architecture is configured to: (i) selectively place the work vehicle MRF joystick system in a modified joystick stiffness mode during operation of the work vehicle; and (ii) when the work vehicle MRF joystick system is placed in the modified joystick stiffness mode, command the MRF joystick resistance mechanism to vary the joystick stiffness based, at least in part, on the movement of the joystick relative to the base housing.Type: GrantFiled: August 25, 2020Date of Patent: November 15, 2022Assignee: DEERE & COMPANYInventors: Alex R. Vandegrift, Craig Christofferson, Amy K. Jones, Anthony K. Kraft, Brett S. Graham, Christopher R. Benson, Christopher J. Meyer, Kenneth Franck, Mark D. Anderson, Todd F. Velde -

The joystick device includes, in turn, a base housing, a joystick, and a joystick position sensor. The MRF joystick resistance mechanism is controllable to selectively resist movement of the joystick relative to the base housing. The controller architecture is configured to: (i) when detecting operator rotation of the joystick in an operator input direction, determine whether continued joystick rotation in the operator input direction will misposition the work vehicle in a manner increasing at least one of work vehicle instability and a likelihood of work vehicle collision; and (ii) when determining that continued joystick rotation will misposition the work vehicle, command the MRF joystick resistance mechanism to generate an MRF resistance force deterring continued joystick rotation in the operator input direction.Type: GrantFiled: May 1, 2020Date of Patent: November 15, 2022Assignee: DEERE & COMPANYInventors: Todd F. Velde, Madeline T. Oglesby, Lance R. Sherlock, Benjamin P. Koestler, Mark D. Anderson, Aaron R. Kenkel, Doug M. Lehmann, Craig Christofferson, Kenneth Franck, Christopher J. Meyer
