Magnetorheological fluid joystick systems reducing work vehicle mispositioning
The disclosure relates to magnetorheological fluid joystick systems reducing work vehicle mispositioning. 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, 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 the rotation of the joystick in an operator input direction by an operator, determine whether continued joystick rotation in the operator input direction will misposition the work vehicle in a manner of 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 for deterring continued joystick rotation in the operator input direction.
本公开涉及减少作业车辆错位的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。操纵杆装置又包括底座壳体、操纵杆和操纵杆位置传感器。MRF操纵杆阻力机构可受控制，以选择性抵抗操纵杆相对于底座壳体的移动。控制器架构被配置为:(i)当检测到操作者将操纵杆在操作者输入方向上的旋转时，确定操纵杆在操作者输入方向上的继续旋转是否将以增加作业车辆不稳定性和作业车辆碰撞的可能性中的至少一种的方式使作业车辆错位；以及(ii)当确定操纵杆继续旋转将使作业车辆错位时，命令MRF操纵杆阻力机构产生MRF阻力，以阻止操纵杆在操作者输入方向上继续旋转。
