Abstract

A system for disabling a vehicle carrying a storage tank includes a coupler component supported by the vehicle for receiving a connection from a delivery line. A cap is attachable to an end of the coupler component for preventing connection of the delivery line when the cap is attached. A proximity sensor is disposed outside of the coupler component and senses whether the cap is attached without making contact with the cap. A switch is in electrically connected to the sensor and disables at least one drive element of the vehicle, e.g., the transmission, when the cap is not attached to the coupler component.

Claims

1. A system for disabling a vehicle carrying a storage tank for holding a substance, said system comprising:

a coupler component supportable by the vehicle for receiving a connection from a delivery line;

said coupler component including a peripheral housing having a first end and a second end and defining an inner passage for accommodating the flow of the substance therethrough and separating said inner passage from an outer region;

a cap attachable to said first end of said coupler component for preventing connection of the delivery line when said cap is attached to said coupler component;

a sensor for sensing whether said cap is attached to said coupler component without making contact with said cap; and

a switch in communication with said sensor and connectable to at least one drive element of the vehicle to disable the at least one drive element of the vehicle when said cap is not attached to said coupler component.

8. A system as set forth in claim 1 wherein said proximity sensor distinguishes between connection of said cap to said coupler component and connection of the delivery line to said coupler component such that the at least one drive element remains disabled by said switch when the delivery line is connected to said coupler component.

9. A system as set forth in claim 1 wherein said sensor is encased within a sensor housing.

10. A system as set forth in claim 9 wherein said sensor housing is formed of a non-conductive material.

11. A system as set forth in claim 9 wherein said sensor housing is formed to mate with at least a portion of said peripheral housing of said coupler component.

12. A system as set forth in claim 9 further comprising a strap assembly for securing said sensor hosing to said coupler component.

13. A system as set forth in claim 12 wherein said strap assembly includes a first strap and a second strap wherein said first strap extends around said sensor housing and said second strap extends through said sensor housing.

14. A system as set forth in claim 9 wherein said sensor housing defines an inner cavity for accommodating said sensor.

15. A system as set forth in claim 14 wherein said sensor housing defines a door for accessing said inner cavity of said sensor housing.

2. A system as set forth in claim 2 wherein said sensor is disposed in said outer region.

3. A system as set forth in claim 2 wherein said cap includes a handle portion for blocking the flow of the substance through said inner passage when attached to said coupler component and a sensing portion disposed in said outer region when attached to said coupler component such that said proximity sensor senses said sensing portion of said cap.

4. A system as set forth in claim 3 wherein said sensing portion of said cap extends from and completely around said handle portion of said cap such that said sensing portion can be sensed by said proximity sensor regardless of a rotational position of said cap.

5. A system as set forth in claim 4 wherein said peripheral housing has a cylindrical shape and said cap has a generally circular shape.

6. A system as set forth in claim 5 wherein said sensing portion is radially outwardly spaced from an outer surface of said coupler component.

7. A system as set forth in claim 3 wherein said sensing portion is generally perpendicular to said peripheral housing.

16. A system for disabling a vehicle carrying a storage tank for holding a substance, said system comprising:

a coupler component supportable by the vehicle and in fluidic communication with the storage tank for receiving a connection from a delivery line;

said coupler component including a peripheral housing having a first end and a second end and defining an inner passage for accommodating the flow of the substance therethrough and separating said inner passage from an outer region;

said first end of said coupler component configured to receive a cap for preventing connection of the delivery line when the cap is attached to said coupler component;

a proximity sensor supported by said peripheral housing for sensing whether the cap is attached to said coupler component without making contact with the cap; and

a switch in communication with said sensor and connectable to at least one drive element of the vehicle to disable the at least one drive element of the vehicle when the cap is not attached to said coupler component.

17. A method for disabling a vehicle carrying a storage tank for holding a substance, the vehicle having a coupler component with at least a first end for receiving connection to a delivery line and accommodating the flow of a substance therethrough, said method comprising the steps of:

electronically sensing whether a cap is attached to the coupler component without making contact with the cap; and

disabling at least one drive element of the vehicle when the cap is not attached to the coupler component.

18. A method as set forth in claim 17 wherein the cap includes a handle portion for blocking the flow of the substance through the coupler component and a sensing portion of the cap extending from the handle portion and said step of sensing whether the cap is attached to the coupler component is further defined as sensing the sensing portion of the cap to determine whether the cap is attached to the coupler component without making contact with the cap.
