Work vehicle magnetorheological fluid joystick systems operable in modified centering modes
The disclosure relates to work vehicle magnetorheological fluid joystick systems operable in modified centering modes. 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 bias mechanism coupled to the joystick and exerting a centering force urging the joystick to return to the centered position when moved therefrom. The controller architecture is operable in a modified centering mode in which the controller architecture: (i) determines when the joystick begins return toward the centered position due to the centering force applied by the joystick bias mechanism to joystick; and (ii) when so determining, commands the MRF joystick resistance mechanism to modify a rate at which the joystick returns to the centered position by varying the MRF resistance force applied to the joystick.
本公开涉及可在修改向心模式下操作的作业车辆磁流变流体操纵杆系统。该作业车辆磁流变流体(MRF)操纵杆系统包括：操纵杆装置、MRF操纵杆阻力机构以及控制器架构。该操纵杆装置又包括：基壳、可移动地安装至基壳的操纵杆以及操纵杆偏置机构，该操纵杆偏置机构联接至操纵杆，并且在操纵杆从中位移开时，施加向心力以促使操纵杆向中位返回。控制器架构能够在经修改的向心模式下操作，其中，控制器架构：(i)确定操纵杆何时因通过操纵杆偏置机构施加至操纵杆的向心力而开始朝着中位返回；以及(ii)在如此确定时，向MRF操纵杆阻力机构发出命令，以通过改变施加至操纵杆的MRF阻力，来修改操纵杆向中位返回的速率。
