Abstract

A vehicular security system includes an alert device disposed in a vehicle equipped with the vehicular security system. Responsive to detection of a vehicle security threat, the alert device transmits a signal to a receiver remote from the vehicle. A jammer detector is disposed at the vehicle and operable to determine jamming of the signal transmitted by the alert device. Responsive to determination by the jammer detector of jamming of transmission of the signal transmitted by the alert device, the vehicular security system at least temporarily disables at least one vehicle access function to reduce likelihood of a break in of the vehicle while the signal transmitted by the alert device is being jammed.

First claim

1 . A vehicular security system, said vehicular security system comprising:
an alert device disposed in a vehicle equipped with said vehicular security system, wherein, responsive to detection of a vehicle security threat, said alert device transmits a signal to a receiver remote from the vehicle; a jammer detector disposed at the vehicle and operable to determine jamming of the signal transmitted by said alert device; and wherein, responsive to determination by said jammer detector of jamming of transmission of the signal transmitted by said alert device, said vehicular security system at least temporarily disables at least one vehicle access function to reduce likelihood of a break in of the vehicle while the signal transmitted by said alert device is being jammed.

2 . The vehicular security system of claim 1 , wherein the at least one vehicle access function comprises an entry system of the vehicle.

3 . The vehicular security system of claim 1 , wherein the at least one vehicle access function comprises a door unlock function responsive to a signal transmitted by a remote transmitter.

4 . The vehicular security system of claim 1 , wherein the at least one vehicle access function comprises vehicle entry access via turning a key in a key hole of a door of the vehicle.

5 . The vehicular security system of claim 1 , wherein said vehicular security system, responsive to determination by said jammer detector of jamming of the signal transmitted by said alert device, operates a door lock function of the vehicle to lock a door of the vehicle.

6 . The vehicular security system of claim 1 , wherein said vehicular security system, responsive to determination by said jammer detector of jamming of the signal transmitted by said alert device, generates a signal that is transmitted to a remote device of an owner of the vehicle to alert the owner of the determination by said jammer detector of jamming of the signal transmitted by said alert device.

7 . The vehicular security system of claim 1 , wherein said vehicular security system, responsive to determination by said jammer detector of jamming of the signal transmitted by said alert device, generates a signal that is transmitted to a security service remote from the vehicle to alert the security service of the determination by said jammer detector of jamming of the signal transmitted by said alert device.

8 . The vehicular security system of claim 1 , wherein said vehicular security system, responsive to determination by said jammer detector of jamming of the signal transmitted by said alert device, limits access to the vehicle until an unlock code is provided.

9 . The vehicular security system of claim 8 , wherein the unlock code is provided via a remote device.

10 . The vehicular security system of claim 1 , wherein said vehicular security system, responsive to determination by said jammer detector of jamming of the signal transmitted by said alert device, limits access to the vehicle until an authorized user is identified at the vehicle via at least one selected from the group consisting of (i) facial recognition, (ii) retinal identification and (iii) fingerprint identification.

11 . The vehicular security system of claim 1 , wherein said vehicular security system comprises at least one camera disposed at the vehicle and operable to capture frames of image data, and wherein said vehicular security system, responsive to the vehicle being in a parked state, and responsive to processing of captured image data, compares frames of captured image data to determine change at an area of the frames of captured image data that is indicative of movement at a region of a field of view of the at least one camera.

12 . The vehicular security system of claim 11 , wherein, responsive to determination of change at the area of the frames of captured image data beyond a threshold degree of change, said vehicular security system starts recording frames of image data captured by the at least one camera.

13 . The vehicular security system of claim 12 , wherein, responsive to determination of the threshold degree of change, said vehicular security system activates at least one other camera or sensor to capture data and said vehicular security system records information captured by the at least one other camera or sensor.

14 . The vehicular security system of claim 13 , wherein the threshold degree of change is dependent upon an amount of time that the vehicle has been in the parked state.

15 . A vehicular security system, said vehicular security system comprising:
an alert device disposed in a vehicle equipped with said vehicular security system, wherein, responsive to detection of a vehicle security threat, said alert device transmits a signal to a receiver remote from the vehicle; a jammer detector disposed at the vehicle and operable to determine jamming of the signal transmitted by said alert device; wherein, responsive to determination by said jammer detector of jamming of transmission of the signal transmitted by said alert device, said vehicular security system at least temporarily disables at least one vehicle access function to reduce likelihood of a break in of the vehicle while the signal transmitted by said alert device is being jammed; wherein the at least one vehicle access function comprises an entry system of the vehicle; and wherein said vehicular security system, responsive to determination by said jammer detector of jamming of the signal transmitted by said alert device, generates a signal that is transmitted to a remote device of an owner of the vehicle to alert the owner of the determination by said jammer detector of jamming of the signal transmitted by said alert device.

16 . The vehicular security system of claim 15 , wherein the at least one vehicle access function comprises a door unlock function responsive to a signal transmitted by a remote transmitter.

17 . The vehicular security system of claim 15 , wherein the at least one vehicle access function comprises vehicle entry access via turning a key in a key hole of a door of the vehicle.

18 . The vehicular security system of claim 15 , wherein said vehicular security system, responsive to determination by said jammer detector of jamming of the signal transmitted by said alert device, operates a door lock function of the vehicle to lock a door of the vehicle.

19 . A vehicular security system, said vehicular security system comprising:
an alert device disposed in a vehicle equipped with said vehicular security system, wherein, responsive to detection of a vehicle security threat, said alert device transmits a signal to a receiver remote from the vehicle; at least one camera disposed at the vehicle and operable to capture frames of image data, wherein said vehicular security system, responsive to the vehicle being in a parked state, and responsive to processing of captured image data, compares frames of captured image data to determine change at an area of the frames of captured image data that is indicative of movement at a region of a field of view of the at least one camera; wherein, responsive to determination of change at the area of the frames of captured image data beyond a threshold degree of change, said alert device transmits the signal; a jammer detector disposed at the vehicle and operable to determine jamming of the signal transmitted by said alert device; wherein, responsive to determination by said jammer detector of jamming of transmission of the signal transmitted by said alert device, said vehicular securit
