Abstract

An anti-theft system for a vehicle includes an on-vehicle machine (10) including reporting means (28) configured to report by radio an illegal activity affecting the vehicle to a designated opponent to be reported to in a case where the illegal activity is detected; and an external facility (30), the external facility (30) including obstruction radio wave detection means (36) configured to detect a radio wave obstructing the radio-report by the reporting means; and illegal activity prevention means (38, 40, 42) configured to prevent the illegal activity in a case where the radio wave is detected by the obstruction radio wave detection means (36). Jamming the radio signal from the vehicle is detected and triggers taking a photograph of the vehicle and its surroundings.

Claims

1. An anti-theft system for a vehicle, comprising:

an on-vehicle machine including reporting means configured to report by radio an illegal activity affecting the vehicle to a designated entitled user to be reported to in a case where the illegal activity is detected; and

an external facility, the external facility including;

obstruction radio wave detection means configured to detect a radio wave obstructing the radio-report by the reporting means; and

illegal activity prevention means configured to prevent the illegal activity in a case where the radio wave is detected by the obstruction radio wave detection means.

2. The anti-theft system for the vehicle as claimed in claim 1,

wherein the illegal activity prevention means issues a warning to an outside as an action to prevent the illegal activity.

3. The anti-theft system for the vehicle as claimed in claim 1,

wherein the illegal activity prevention means reports the existence of the radio wave to the designated entitled user to be reported to as an action to prevent the illegal activity.

4. The anti-theft system for the vehicle as claimed in claim 1,

wherein the external facility further includes photographing means configured to photograph a parked vehicle,

the illegal activity prevention means reports the existence of the radio wave to the designated entitled user to be reported to and sends an image photographed by the photographing means in a case where the radio wave is detected by the obstruction radio wave detection means.

5. The anti-theft system for the vehicle as claimed in claim 3 or 4,

wherein the external facility is provided in a parking lot where an unspecified large number of the vehicles are parked, and

the external facility obtains information necessary for the report from the parked vehicle.

6. (canceled)

7. An anti-theft device for a vehicle, comprising:

reporting means configured to report by radio an illegal activity affecting the vehicle to a designated entitled user to be reported to in a case where the illegal activity is detected;

obstruction radio wave detection means configured to detect a radio wave obstructing the radio-report by the reporting means; and

illegal activity prevention means configured to prevent the illegal activity in a case where the radio wave is detected by the obstruction radio wave detection means.

8. The anti-theft device for the vehicle as claimed in claim 7,

wherein the illegal activity prevention means issues a warning to an outside as an action to prevent the illegal activity.
