Abstract

An apparatus and method are disclosed for positioning a movable component of a motor actuated device. The apparatus for carrying out the method includes a speech sensor for receiving speech input provided by a user of the device, and a force sensor for measuring a force input provided by the device user. The apparatus further includes a controller coupled to the speech sensor, the force sensor, and the motor actuated vehicle accessory, where the controller is operable to position the movable component in accordance with the received speech input and the measured force input. Exemplary embodiments are presented where the principles of the disclosure are applied to adjust the positioning of movable components of an adjustable pedal assembly and a vehicle power seat.

The apparatus of claim 2, wherein after the start speech command is received, the movable component is moved in a first direction when the magnitude of the force input applied by the user of the device has a magnitude less than the first predetermined amount of force, and in a second direction when the magnitude of the force input is greater than the second predetermined amount of force.

6. The apparatus of claim 5, wherein movement of the movable component is halted when the magnitude of the force input applied by the user of the device is greater than the first predetermined amount of force and less than the second predetermined amount of force.

7. The apparatus of claim 1, wherein adjustment of the positioning of the movable component is terminated when the user of the device applies, and then removes the force input.

8. The apparatus of claim 1, wherein the magnitude of the force input provided by the user of the device is applied to the movable component to oppose movement in a first direction and to assist movement in a second direction.

9. The apparatus of claim 1, wherein said device is a vehicle adjustable pedal assembly and said movable component comprises a pedal arm.
