Abstract

A system and computer-implemented method for detecting concealed cargo and/or concealed passengers in a vehicle includes obtaining weight distribution data for the vehicle; obtaining vehicle loading data; measuring a center of mass of the vehicle to obtain an actual center of mass position of the vehicle; and executing one or more computer program modules configured to determined a predicted center of mass position of the vehicle using the obtained vehicle loading data and the obtained weight distribution data of the vehicle; compare the actual center of mass position of the vehicle with the predicted center of mass position of the vehicle; and provide a signal if the actual center of mass position of the vehicle departs from the predicted center of mass position of the vehicle by at least a predetermined threshold, the signal being representative of concealed cargo and/or concealed passengers in the vehicle.

Claims

1. A computer-implemented method for detecting concealed cargo and/or concealed passengers in a vehicle, wherein the method is implemented in a computer system comprising one or more processors configured to execute one or more computer program modules, the method comprising:

obtaining weight distribution data for the vehicle using a vehicle identifying system;

obtaining vehicle loading data;

measuring a center of mass of the vehicle using a weight scale system to obtain an actual center of mass position of the vehicle; and

executing, on the one or more processors of the computer system, one or more computer program modules configured to;

predict a center of mass position of the vehicle using the obtained vehicle loading data and the obtained weight distribution data of the vehicle;

compare the actual center of mass position of the vehicle with the predicted center of mass position of the vehicle; and

provide an error signal if the actual center of mass position of the vehicle departs from the predicted center of mass position of the vehicle by at least a predetermined threshold, the error signal being representative of concealed cargo and/or concealed passengers in the vehicle.

2. The method of claim 1, further comprising executing, on the one or more processors of the computer system, one or more computer program modules configured to determine one or more particular locations where the concealed cargo and/or the concealed passenger is in the vehicle.

3. The method of claim 2, wherein the one or more particular locations includes a dashboard space, an instrument panel space, a trunk compartment, a passenger space, or an engine compartment of the vehicle.

4. The method of claim 1, wherein each of the actual center of mass position of the vehicle and the predicted center of mass position of the vehicle are calculated in a two-dimensional space.

5. The method of claim 1, wherein each of the actual center of mass position of the vehicle and the predicted center of mass position of the vehicle are calculated in a three-dimensional space.

6. The method of claim 5, further comprising executing, on the one or more processors of the computer system, one or more computer program modules configured to determine a height of the actual center of mass position of the vehicle and a height of the predicted center of the mass position of the vehicle.

7. The method of claim 1, wherein the vehicle loading data comprises number of passengers in the vehicle, location of the passengers in the vehicle, sex of the passengers in the vehicle, body structure of the passengers, fuel tank level in the vehicle, a mode of travel and/or whether one or more of the passengers in the vehicle is an adult or a child.

8. The method of claim 7, wherein the mode of travel is a vacation mode.

9. The method of claim 1, wherein the predetermined threshold is equal to at least a portion of a weight of full tank of gas of the vehicle.

10. A system for detecting concealed cargo and/or concealed passengers in a vehicle, the system comprising:

a vehicle identifying system configured to obtain weight distribution data for the vehicle;

a weight scale system configured to measure a center of mass of the vehicle to obtain an actual center of mass position of the vehicle;

a processor configured to;

receive vehicle loading data;

predict a center of mass position of the vehicle using the vehicle loading data and the weight distribution data of the vehicle;

compare the actual center of mass position of the vehicle with the predicted center of mass position of the vehicle; and

provide an error signal if the actual center of mass position of the vehicle departs from the predicted center of mass position of the vehicle by at least a predetermined threshold, the error signal being representative of concealed cargo and/or concealed passengers in the vehicle.

11. The system of claim 10, wherein the processor is further configured to determine one or more particular locations where the concealed cargo and/or the concealed passenger is in the vehicle.

12. The system of claim 10, wherein the vehicle identifying system comprises a database and a vehicle identifier.

13. The system of claim 12, wherein the vehicle identifier comprises a license plate reader, a VIN number reader, a RF tag reader, or an Automatic Target Recognition device.

14. The system of claim 10, wherein the predetermined threshold is equal to at least a portion of a weight of full tank of gas of the vehicle.

15. The system of claim 10, wherein the weight scale system comprises a plurality of sectional scales, one sectional scale for each wheel of the vehicle.

16. The system of claim 15, wherein the plurality of sectional scales includes at least two sectional scales.

17. The system of claim 15, wherein the plurality of sectional scales includes at least four sectional scales.

18. The system of claim 17, wherein two rear sectional scales are configured to be longer than two front sectional scales to accommodate different wheelbase length of the vehicle.

19. The system of claim 10, wherein the processor is further configured to determine a difference between an actual weight of the vehicle and an predicted weight of the vehicle, wherein the actual weight of the vehicle is measured using the weight scale system and the predicted weight of the vehicle is determined using the vehicle loading data and the weight distribution data.

20. The system of claim 19, wherein the processor is further configured to use the weight difference and the provided signal to detect the concealed cargo and/or the concealed passengers in the vehicle.

21. A shared network system comprising a plurality of geographically separate systems for detecting concealed cargo and/or concealed passengers in a vehicle, each system in said plurality of systems comprising:

a vehicle identifying system configured to obtain weight distribution data for the vehicle;

a weight scale system configured to measure a center of mass of the vehicle to obtain an actual center of mass position of the vehicle;

a processor configured to;

receive vehicle loading data;

predict as center of mass position of the vehicle using the vehicle loading data and the weight distribution data of the vehicle;

compare the actual center of mass position of the vehicle with the predicted center of mass position of the vehicle;

provide an error signal if the actual center of mass position of the vehicle departs from the predicted center of mass position of the vehicle by at least a predetermined threshold, the error signal being representative of concealed cargo and/or concealed passengers in the vehicle; and

store information about the vehicle after validating the provided error signal, wherein the shared network system is configured to share the information about the vehicle between the plurality of systems over a networked connection.

22. The shared network system of claim 21, further comprising

a) a centralized database configured to store the information about the vehicle;

and

b) a server system configured to be coupled with each of the plurality of systems and the centralized database, the server system further configured to;
