Abstract

Disclosed is a system for controlling a mobility device including a processor configured for a workflow process configured for filtering user commands based on a status of the mobility device and defining filtered commands. A mobility device command process is configured for issuing commands based on the filtered commands. The mobility device responds to the commands that are configured for controlling moving the mobility device.

Claims (28)

1. System for controlling a mobility device comprising a processor configured for:

a workflow process configured for filtering user commands based on a status of said mobility device and defining filtered commands; and

a mobility device command process configured for issuing commands based on the filtered commands;

wherein said mobility device is configured for responding to the commands that are configured for controlling moving said mobility device.

2. System of claim 1 wherein the mobility device command process is configured for issuing commands to the mobility device based on sensor data.

3. System of claim 2 wherein the sensor data relate to obstacles in a path of said mobility device.

4. System of claim 1 further comprising a user interface subsystem comprising:

a user input device configured for receiving user commands;

a user command processor configured for processing the user commands;

a user output device configured for transmitting information from said user command processor to said mobility device command process.

5. System of claim 4 further comprising a data exchange port configured for exchanging data between the user interface subsystem and said mobility device command process.

6. System of claim 4 further comprising a power supply port configured for powering said user interface subsystem.

7. System of claim 4 wherein said user input device comprises a thumbwheel configured for providing movement data throughout a full rotation of the thumbwheel and thumbwheel position, wherein:

said user interface subsystem is configured for retaining the thumbwheel position across a power cycle; and

the thumbwheel position is associated with a user interface subsystem characteristic.

8. System of claim 1 wherein said workflow process is configured for:

responding to a subflow process;

providing a command from a set of allowed commands to said mobility device; and

being selected based on the user commands.

9. System of claim 1 wherein said workflow process comprises one or more of:

a normal workflow comprising: a speed selection, a settings selection, a seat adjustment selection, a mode selection, and combinations thereof;

a power button workflow configured for being responsive to subflow process based on a status of a power button and comprising: an emergency stop, a revert to a previous button status, and combinations thereof;

a stair mode workflow comprising a solo mode stair climbing, an assisted mode stair climbing, and combinations thereof;

a forced power off workflow comprising insuring a power off selection and powering the mobility device off;

a center of gravity fit workflow comprising calibrating the mobility device for a user;

a recovery mode workflow comprising providing recovery information to the user; and

a wireless workflow comprising requesting a password from the user.

10. System of claim 1 wherein said mobility device command process is configured for managing changes in operating modes of said mobility device based on a power capability.
