Systems and Methods for Controlling Mobility Devices
Embodiments of a mobility vehicle control system are provided. In one embodiment, a head array and control system are provided that allow for adjustment of a plurality of parameters associated with the head array including, for example, sensor pad settings, user settings, and feature settings. A veer adjust interface is also provided as a performance setting adjustment to allow for correction of any veer by the vehicle when being driven.
1 . A mobility vehicle comprising:
a first controller for controlling the speed and direction of the vehicle,
a head array connected to a second controller,
the second controller in communication with the first controller and wherein the second controller comprises:
a display and at least one input device; and
logic for correcting the veer of the vehicle.
2 . The vehicle of claim 1 wherein the logic for correcting the veer of the vehicle comprises logic for generating a veer adjustment display.
3 . The vehicle of claim 1 wherein the logic for correcting the veer of the vehicle comprises logic for reading a veer adjustment input.
4 . The vehicle of claim 1 wherein the logic for correcting the veer of the vehicle comprises logic for modifying a drive direction signal by a veer adjustment signal.
5 . The vehicle of claim 2 wherein the logic for generating a veer adjustment display includes logic for generating a graphical veer adjustment selector.
6 . The vehicle of claim 3 wherein the logic for generating a graphical veer adjustment selector includes logic for generating a graphical slider bar and slider knob.
7 . The vehicle of claim 6 wherein the logic for logic for correcting the veer of the vehicle comprises logic for reading the position of the graphical slider knob on the slider bar to generate a veer adjustment value.
8 . The vehicle of claim 7 wherein the logic for correcting the veer of the vehicle comprises logic for combining the drive direction signal from the head array with the veer adjustment value.
9 . The vehicle of claim 1 wherein the logic for correcting the veer of the vehicle comprises logic for combining a drive direction signal from the head array with a veer adjustment value input by the user to generate a corrected drive signal.
10 . The vehicle of claim 9 wherein the logic for correcting the veer of the vehicle comprises logic for sending the corrected drive signal to the first controller for driving the power wheelchair.
11 . A mobility vehicle comprising:
a head array control system having:
a head array with at least one sensor pad;
a control interface for interpreting signals from the head array and providing vehicle speed and direction signals; and
a head array programmer and display for adjusting the settings of the head array, wherein the head array programmer comprises a veer adjustment interface for allowing a veer adjust parameter to be defined for correcting the veer of the vehicle.
12 . The mobility vehicle of claim 11 wherein the veer adjustment interface comprises a graphical input display.
13 . The mobility vehicle of claim 11 wherein the veer adjust interface comprises a graphical slider bar having a slide knob that is movable by a user input.
14 . The mobility vehicle of claim 11 wherein the veer adjust interface comprises logic for combining the veer adjust parameter with a drive direction control signal from the head array.
15 . The mobility vehicle of claim 11 wherein the veer adjust interface comprises logic for limiting the veer adjust parameter to a positive and negative range of values.
16 . A mobility vehicle comprising:
a head array control means having:
a head array means;
a control interface means for interpreting signals from the head array means and providing vehicle speed and direction signals; and
a head array programmer and display means for adjusting the settings of the head array control means, wherein the head array programmer means comprises a veer adjustment interface means for allowing a veer adjust parameter to be defined for correcting the veer of the vehicle.
17 . The mobility vehicle of claim 16 wherein the veer adjustment interface means comprises a graphical means for input.
18 . The mobility vehicle of claim 16 wherein the veer adjust interface means comprises a means for generating and sensing the movement of a graphical slider bar having a slide knob.
19 . The mobility vehicle of claim 16 wherein the veer adjust interface means comprises means for combining the veer adjust parameter with a drive direction control signal from the head array means.
20 . The mobility vehicle of claim 16 wherein the head array programmer and display means comprise a means for adjusting the sensor pad type of the head array means.
