Beschreibung
Zusammenfassung:	Embodiments of a work vehicle magnetorheological fluid (MRF) joystick system includes a joystick device having a base housing, a joystick movably mounted to the base housing, and a joystick position sensor monitoring movement of the joystick relative to the base housing. An MRF joystick resistance mechanism is controllable to vary a joystick stiffness resisting movement of the joystick relative to the base housing in at least one degree of freedom. A controller architecture is coupled to the joystick position sensor and to the MRF joystick resistance mechanism. The controller architecture is configured to: (i) command the MRF joystick resistance mechanism to increase the joystick stiffness when the joystick is moved into a first predetermined detent position to generate a first MRF detent; and (ii) selectively activate a first detent-triggered function of the work vehicle based, at least in part, on joystick movement relative to the first MRF detent.
