Abstract
A control system is disclosed. The control system may include a first input component to control a lean angle of at least one set of wheels of a machine and to provide a visual and/or tactile indication of the lean angle. The control system may include a second input component to control an articulation angle of an articulated joint of the machine and to provide a visual and/or tactile indication of the articulation angle. The control system may include a third input component to control a rotation angle of an implement of the machine and to provide a visual and/or tactile indication of the rotation angle.
Claims20
A motor grader comprising:
- a steerable traction device operatively connected to a first set of wheels;
- a driven traction device operatively connected to a second set of wheels;
- a frame having an articulated joint connecting the steerable traction device to the driven traction device;
- an implement operatively connected to the frame;
- and
- a control system including a joystick, the control system configured to:
- control, based on a displacement associated with the joystick and after an operator disengages the joystick, one or more of a lean angle of the first set of wheels, an articulation angle of the articulated joint, and/or a rotation angle of the implement;
- and
- cause a tactile indication via the joystick after one or more of:
- the lean angle of the first set of wheels matching the displacement associated with the joystick,
- the articulation angle of the articulated joint matching the displacement associated with the joystick, and/or
- the rotation angle of the implement matching the displacement associated with the joystick,
- wherein the tactile indication includes a vibration.
A control system for a motor grader, comprising:
- a joystick;
- and
- one or more processors associated with the joystick, configured to:
- control an angle of a work element of the motor grader based on a displacement associated with the joystick and after an operator disengages the joystick,
- wherein the angle of the work element includes at least one of:
- a lean angle of a set of wheels,
- an articulation angle of an articulated joint, and/or
- a rotation angle of an implement;
- and
- cause a tactile indication via the joystick after the angle of the work element matches the displacement associated with the joystick,
- wherein the tactile indication includes a vibration.
A machine comprising:
- a control system including a joystick, the control system configured to:
- control, based on a displacement associated with the joystick and after an operator disengages the joystick, one or more of a lean angle of a set of wheels, an articulation angle of an articulated joint, and/or a rotation angle of an implement;
- and
- cause a tactile indication via the joystick after one or more of:
- the lean angle of the set of wheels matching the displacement associated with the joystick,
- the articulation angle of the articulated joint matching the displacement associated with the joystick, and/or
- the rotation angle of the implement matching the displacement associated with the joystick,
- wherein the tactile indication includes a vibration.
