Abstract

A system and method for automatically inflating tires mounted on a vehicle without requiring the occupants of the vehicle from leaving the interior of the vehicle. In one aspect, the present invention is directed to a system for automatically inflating a tire of a vehicle. The system determines a location of a valve stem of the tire and a robotic arm for inflating the tire. The robotic arm attaches to the located valve stem based on the determined valve stem location. The robotic arm supplies air to the tire from an air supply. The valve stem is located and the robotic arm attaches to the valve stem based on the determined valve stem location, inflates the tire and detaches from the tire upon determining that a predetermined tire air pressure is attained.

Claims

means for determining a location of a valve stem of the tire;

an air supply; and

a robotic arm for inflating the tire, the robotic arm attaching to the located valve stem based on the determined valve stem location and supplying air to the tire from the air supply;

whereby the valve stem is located and the robotic arm attaches to the valve stem based on the determined valve stem location, inflates the tire and detaches from the tire upon determining that a predetermined tire air pressure is attained.

2. The system according to claim 1 wherein the means for determining a location of a valve stem of the tire is an optical system for visually determining the location of the valve stem.

3. The system according to claim 2 wherein the optical system includes at least one camera for visually detecting the valve stem.

4. The system according to claim 1 wherein the means for determining a location of the valve stem of the tire is a scanner module for emitting a structured light for determining the location of the valve stem.

5. The system according to claim 1 further comprising means for monitoring air pressure of the tire.

6. The system according to claim 1 wherein the robotic arm includes an infrared temperature module for monitoring the temperature of the tire.

7. The system according to claim 1 wherein the robotic arm is mounted on a rail allowing horizontal movement of the robotic arm relative to the vehicle.

8. The system according to claim 1 wherein the robotic arm includes means for moving in a plurality of axis relative to the vehicle.

9. The system according to claim 1 wherein the robotic arm includes an extension having an air chuck for supplying air from the air supply to the tire and a cap tool for removing and attaching a valve stem cap to the valve stem.

10. The system according to claim 9 wherein the cap tool includes a plurality of telescopic fingers for grasping the cap.

11. The system according to claim 1 wherein the tire of the vehicle includes a fill through cap which enables inflation of the tire without removal of the cap.

12. The system according to claim 1 further comprising a payment mechanism enabling a driver of the vehicle to pay for using the system for automatically inflating a tire.

13. A method of automatically inflating a tire mounted on a vehicle, the method comprising the steps of:

determining a location of a valve stem of the tire;
