Abstract

An integrated and autonomous mobility system for disabled persons including an automated wheelchair (AV) and an Adapted Automated Vehicle (AAV) configured to work together as an integrated unit to transport a user to a pre-selected destination with little to no input from the user during the trip. The AV is also configured to operate independently of the AAV to transport the user on shorter trips, or to continue a journey after the AAV has transported the AW to an intermediate destination. Multiple safety systems are included. The system has an override function according to which a user can interrupt the automated transport operation and cause the AV and/or AAV to stop, slow down, speed up, or change direction.

Claims (29)

1 . A device comprising:

a wheelchair having a user seat and seat back;

drive wheels;

a motor coupled to said drive wheels,

a wheelchair computer in electronic communication with said motor, said wheelchair computer including a processor and non-transient memory, said non-transient memory including a global positioning system (GPS) and a navigation software module;

said wheelchair further comprising:

an input device in electronic communication with said wheelchair computer;

inertial sensors in electronic communication with said wheelchair computer;

a plurality of ultrasonic sensors in electronic communication with said wheelchair computer and configured to detect obstacles on or near a travel path of said device;

at least one Quick Response (QR) code reader in electronic communication with said wheelchair computer and configured to read QR codes;

a manual override input device in electronic communication with said wheelchair computer and configured to send a navigation interrupt signal to said navigation system;

an emergency contact input device in electronic communication with emergency service providers;

an antenna in electronic communication with said wheelchair computer configured for cellular-based internet connection;

said device further comprising:

a single occupancy level 4 or higher automated self-driving vehicle (AAV), said AAV comprising:

a wheelchair loading device;

a wheelchair securing mechanism;

an AAV onboard computer including a processor and non-transient memory configured to communicate wirelessly with said wheelchair computer to automatically activate said wheelchair loading device when said wheelchair approaches said AAV, to activate said wheelchair securing mechanism when said wheelchair is in an AAV transport position,

wherein said wheelchair computer is configured to automatically hand over automated driving functions to the AAV onboard computer via electronic handshake once said wheelchair has entered said AAV, and wherein said AAV onboard computer is configured to accept automated navigation control from said wheelchair computer,

said wheelchair computer further configured to automatically disengage said wheelchair from said wheelchair securing mechanism when said AAV has arrived at an intermediate destination, automatically move to the wheelchair loading device, and automatically navigate to a final destination.

2 . The device according to claim 1 , said wheelchair further comprising a canopy to protect the user from sun, rain, wind and/or snow.

3 . The device according to claim 1 , said wheelchair further including a mobile computing device holder.

4 . The device according to claim 1 , said wheelchair computer in electronic communication with a health care language interpreter network to assist users with language barriers.

5 . The device according to claim 1 , wherein said QR code readers configured to follow navigation lines and for identifying location(s) of the wheelchair.

6 . The device according to claim 1 , said input device configured to receive voice and/or text instructions.

7 . The device according to claim 1 , wherein said navigation software module is configured to receive instructions via said input device or from a remote device via wireless communication.

8 . The device according to claim 1 , said wheelchair further comprising a size-adjustable cargo carrier.

9 . The device according to claim 1 , wherein said manual override input device is a joystick.

10 . An autonomous mobility system comprising the device of claim 1 and further comprising a plurality of printed QR codes placed on the ground along potential or actual AW travel routes.
