Haptic control devices
A haptic control device for use in control-by-wire systems in vehicles. The haptic shift device includes a manipulandum manipulatable by a user. At least one sensor detects a position of the manipulandum. At least one electrically-controlled actuator outputs a force on the shift lever. In some embodiments, the manipulandum is moveable within a pattern and is blocked from areas outside the boundaries of the pattern. The actuator(s) can be active or passive, and/or a variable mechanical gate can be used to implement the pattern. Provided modes can include automatic, manual, and/or sequential modes.
1. An apparatus, comprising:
a manipulandum;
a sensor configured to detect a position of the manipulandum and output a sensor signal associated with the position to a processor;
an actuator coupled to the manipulandum and configured to output a haptic effect based at least in part on the sensor signal; and
a mechanical gate corresponding to a predetermined pattern, the haptic effect and the mechanical gate substantially constraining the manipulandum to be moveable within the predetermined pattern.
2. The apparatus of claim 1 , wherein the manipulandum comprises one of a control lever, a control knob, a mouse, or a trackball.
3. The apparatus of claim 1 , wherein the actuator comprises at least one of an active actuator or a resistive actuator.
4. The apparatus of claim 1 , wherein the haptic effect comprises a barrier force.
5. The apparatus of claim 1 , wherein the haptic effect further imparts a haptic sensation on the manipulandum.
6. The apparatus of claim 5 , wherein the haptic sensation comprises at least one of a detent sensation, a hill sensation, a spring sensation, a jolt sensation, a damping sensation, a vibration sensation, or a texture sensation.
7. The apparatus of claim 1 , wherein the actuator comprises a first actuator and further comprising a second actuator, the first actuator configured to output the barrier force, and the second actuator configured to impart the haptic sensation.
8. The apparatus of claim 7 , wherein the first actuator comprises one of a resistive actuator or an active actuator, and the second actuator comprises one of a resistive actuator or an active actuator.
9. The apparatus of claim 1 , wherein the manipulandum is coupled to a five-member closed-loop gimbal mechanism and is moveable in two degrees of freedom.
10. The apparatus of claim 1 , wherein the processor is further configured to receive a selection associated with one of a plurality of modes from a mode selector, and control the actuator such that the manipulandum is substantially constrained to move in a pattern corresponding with the selected mode.
11. The apparatus of claim 1 , wherein the mechanical gate is a variable mechanical gate having at least one mechanically moving component that allows a plurality of predefined patterns to be provided for the manipulandum in a plurality of modes.
12. The apparatus of claim 11 , wherein the at least one mechanically moving component includes a gate component that is configured to be moved to open or block a channel of at least one of the predefined patterns.
13. The apparatus of claim 12 , wherein the at least one mechanically moving component includes a plurality of gate fingers that are configured to slide to block a horizontal or vertical channel in the predetermined pattern of a manual mode.
14. The apparatus of claim 1 , further comprising a display device in communication with the processor, the processor configured to cause the predetermined pattern to display on the display device.
15. A method, comprising:
receiving a sensor signal associated with a position of a manipulandum; and
outputting an actuator signal to an actuator coupled to the manipulandum, the actuator signal configured to cause the actuator to output a haptic effect based at least in part on the sensor signal, the haptic effect and a mechanical gate substantially constraining the manipulandum to be moveable within a predetermined pattern.
16. The method of claim 15 , further comprising moving the manipulandum within the predetermined pattern.
17. The method of claim 16 , further comprising outputting a haptic sensation based at least in part on the movement of the manipulandum.
18. The method of claim 17 , wherein the haptic sensation comprises at least one of a detent sensation, a hill sensation, a spring sensation, a jolt sensation, a damping sensation, a vibration sensation, or a texture sensation.
19. The method of claim 15 , further comprising outputting one of an active force or a passive force on the manipulandum.
20. The method of claim 15 , further comprising outputting both an active force and a passive force on the manipulandum.
21. The method of claim 15 , further comprising displaying the predetermined pattern on a display device.
22. The method of claim 15 , further comprising reconfiguring the mechanical gate to provide a second predefined pattern.
