Abstract
A motor-driven feedback mechanism for a braking pedal. A pedal is linked to a shaft and a bi-directional motor capable of operating in a first and a second direction is linked to the shaft. A gearbox is driven by the bi-directional motor and the gearbox is attached to the shaft to effect rotation of the pedal. A motor controller is linked to the motor and a microprocessor capable of controlling the motor controller is linked to the motor controller. At least one sensor for measuring a parameter of the pedal and providing feedback to the microprocessor is provided.

16. A motor-driven feedback mechanism, said mechanism comprising:
-
a pedal pivotally mounted to a frame via a shaft;
a bi-directional motor capable of applying resistance to rotation and assistance to rotation of said pedal;
a means for measuring a least one parameter of said pedal;
a means for analyzing said at least one parameter of said pedal; and
a means for controlling said bi-directional motor to adjust the direction and speed of said bi-directional motor in response to said at least one measured parameter of said pedal. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A method for providing force feedback to an operator of a shaft-mounted pedal, said method comprising the steps of:
-
measuring at least one parameter of a pedal pivotally linked to a frame;
analyzing said at least one parameter to determine operator intent;
signaling a motor controller; and
variably adjusting the direction of rotation and power of a motor to provide mechanical assistance to rotation and resistance to rotation of said pedal and shaft. - View Dependent Claims (24, 25, 26)
