Work vehicle magnetorheological fluid joystick systems reducing unintended joystick motions
The disclosure relates to work vehicle magnetorheological fluid joystick systems reducing unintended joystick motions. 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 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 whether 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 of reducing susceptibility of the joystick device to unintended joystick motions.
本公开涉及减小了意外操纵杆运动的作业车辆磁流变流体操纵杆系统。在实施方式中，一种作业车辆磁流变流体(MRF)操纵杆系统包括操纵杆装置、MRF操纵杆阻力机构和控制器架构。操纵杆装置进而包括底座壳体、能移动地安装于底座壳体的操纵杆以及被配置为监视操纵杆相对于底座壳体的移动的操纵杆位置传感器。MRF操纵杆阻力机构能受到控制以改变第一操纵杆刚度，所述第一操纵杆刚度改变抵抗操纵杆相对于底座壳体的至少一个自由度的移动。控制器架构被配置为:(i)检测在作业车辆操作期间是否出现意外操纵杆运动条件；以及(ii)当检测到意外操纵杆运动条件时，命令MRF操纵杆阻力机构按减小操纵杆装置对意外操纵杆运动的敏感度的方式增加第一操纵杆刚度。
