Work vehicle magnetorheological fluid joystick systems operable in modified joystick stiffness modes
The invention relates to work vehicle magnetorheological fluid joystick systems operable in modified joystick stiffness modes. 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.
本发明涉及在修改后的操纵杆刚度模式下可操作的作业车辆磁流变流体操纵杆系统。作业车辆磁流变流体(MRF)操纵杆系统的实施方式包括具有底座壳体的操纵杆装置、可移动地安装到底座壳体的操纵杆、以及被配置为监视操纵杆移动的操纵杆位置传感器。MRF操纵杆阻力机构可受控制，以在控制器架构联接到操纵杆位置传感器和MRF操纵杆阻力机构的同时，改变抵抗操纵杆相对于底座壳体移动的操纵杆刚度。控制器架构被配置为：(i)在作业车辆操作期间，将作业车辆MRF操纵杆系统选择性地置于修改后的操纵杆刚度模式；(ii)当作业车辆MRF操纵杆系统置于修改后的操纵杆刚度模式时，命令MRF操纵杆阻力机构至少部分地基于操纵杆相对于底座壳体的移动来改变操纵杆刚度。
