Active force/vibration feedback control method and apparatus for a movable machine
A movable machine including a chassis, a tool coupled to the chassis, an operator control carried by the chassis and a controller. The controller is communicatively coupled to the operator control. The controller being configured to send a force feedback and/or a vibration feedback to the operator control thereby conveying information to the operator. The information is not related to a load encountered by the tool.
1. A movable machine, comprising:
a chassis;
an operator control carried by the chassis; and
a controller communicatively coupled to the operator control, the controller configured to send at least one of a force feedback or a vibration feedback to the operator control based on a terrain across which the movable machine is traveling;
wherein the at least one of the force feedback or the vibration feedback is altered by the controller based on at least one of a detection of a rough terrain by a sensor detecting variations in the terrain or a detected obstacle by an obstacle sensor.
2. The movable machine of claim 1 , wherein the at least one of the force feedback or the vibration feedback is altered by the controller based on the detected obstacle being detected by a side of the machine or behind the machine.
3. The movable machine of claim 1 , wherein the at least one of the force feedback or the vibration feedback is altered by the controller based on the detection of the rough terrain which the machine is about to traverse.
4. The movable machine of claim 1 , wherein the at least one of the force feedback or the vibration feedback to the operator control is in a form of at least one of an increased stiffness of the operator control, a decreased stiffness of the operator control, a preventing of movement of the operator control, a shaking of the operator control, a variable frequency movement of the operator control, or a fixed frequency movement of the operator control.
5. The movable machine of claim 4 , wherein the at least one of the force feedback or the vibration feedback is altered by the controller in a single axis of movement of the operator control.
6. The movable machine of claim 4 , wherein the at least one of the force feedback or the vibration feedback to the operator control is in the form of the increased stiffness of the operator control, the controller further configured to decrease the stiffness of the operator control when the rough terrain is no longer present.
7. The movable machine of claim 1 , wherein the controller is further configured to determine the presence of the rough terrain when a predetermined amount of bounce is experienced by the movable machine.
8. A movable machine, comprising:
a chassis;
an operator control carried by the chassis, the operator control configured to control an operation of a component of the movable machine; and
a controller communicatively coupled to the operator control, the controller configured to send at least one of a force feedback or a vibration feedback to the operator control when the movable machine receives a communication from a device other than the moveable machine.
9. The movable machine of claim 8 , wherein the communication is an alert from a communication device.
10. The movable machine of claim 8 , wherein the at least one of the force feedback or the vibration feedback to the operator control is in a form of at least one of an increased stiffness of the operator control, a decreased stiffness of the operator control, a preventing of movement of the operator control, a shaking of the operator control, a variable frequency movement of the operator control, or a fixed frequency movement of the operator control.
11. The movable machine of claim 10 , wherein at least one of the force feedback or the vibration feedback is altered by the controller in a single axis of movement of the operator control.
12. A movable machine, comprising:
a chassis;
an operator control carried by the chassis, the operator control configured to control an operation of a component of the movable machine; and
a controller communicatively coupled to the operator control, the controller configured to send at least one of a force feedback or a vibration feedback to the operator control when an active fault code associated with the movable machine is present;
wherein the at least one of the force feedback or the vibration feedback is applied by the controller along a feedback axis of the operator control and the feedback axis is different from an axis along which the operator control is being used by the operator.
13. The movable machine of claim 12 , wherein the controller is further configured to send the at least one of the force feedback or the vibration feedback to the operator control until the active fault code is cleared.
14. The movable machine of claim 12 , wherein the at least one of the force feedback or the vibration feedback to the operator control is in a form of at least one of an increased stiffness of the operator control, a decreased stiffness of the operator control, a preventing of movement of the operator control, a shaking of the operator control, a variable frequency movement of the operator control, or a fixed frequency movement of the operator control.
