Abstract

The vehicle security system contains an image recorder module, a navigation and positioning module, a storage module, at least a security and surveillance module, and a central processing unit. The image recorder module captures at least a target vehicle'"'"'s image. The navigation and positioning module produces a location coordinate. The storage module stores an electronic map. The security and surveillance module performs identification to the image. The central processing unit receives the image and then produces and stores at least an identification parameter in the storage module. The security and surveillance module then determines if the identification parameter satisfies a preset alarm condition. If the preset alarm condition is satisfied, a warning signal is produced and delivered to the central processing unit which, according to the location coordinate and the electronic map, produces navigation guidance and warning message.

Claims

1. A vehicle security system installed in a subject vehicle, comprising:

an image recorder module capturing at least a target vehicle'"'"'s image;

a navigation and positioning module producing a location coordinate;

a storage module storing an electronic map;

at least a security and surveillance module performing identification to the image; and

a central processing unit coupled to the image recorder module, navigation and positioning module, storage module, and security and surveillance module;

wherein the central processing unit receives the image and then produces and stores at least an identification parameter in the storage module;

the security and surveillance module then determines if the identification parameter satisfies a preset alarm condition; and

, if the preset alarm condition is satisfied, the security and surveillance module produces a warning signal to the central processing unit which in turn, according to the location coordinate and the electronic map, produces navigation guidance and warning message.

2. The vehicle security system according to claim 1, wherein the image recorder module comprises an image capture unit positioned at an appropriate place in the subject vehicle.

3. The vehicle security system according to claim 1, wherein the security and surveillance module comprises a follower identification module determining that the subject vehicle is being followed if the image of a target vehicle is repeatedly captured around the subject vehicle within a preset mileage range.

4. The vehicle security system according to claim 1, wherein the security and surveillance module comprises a reckless driver identification module that conducts focusing on the image of a target vehicle and then, based on the target vehicle'"'"'s focal length, speed, and out of focus or not, determines if the target vehicle is driven by a reckless driver.

5. The vehicle security system according to claim 1, further comprising an operation interface and a display interface, both coupled to the central processing unit wherein the operation interface allows a driver of the subject vehicle to conduct function selection and control;

and the display interface notifies the driver about the warning message issued from the central processing unit.

6. A vehicle security method for a subject vehicle comprising the steps of:

capturing an image of at least a target vehicle by an image recorder module;

processing the captured image by a central processing unit to produce and store an identification parameter in a storage module;

determining if the identification parameter satisfies a preset warning condition and, if yes, producing a warning signal to the central processing unit by a security and surveillance module; and

producing navigation guidance and warning message by the central processing unit based on a location coordinate received from a navigation and positioning module and an electronic map stored in a storage module.

7. The vehicle security method according to claim 6, wherein the security and surveillance module comprises a follower identification module determining that the subject vehicle is being followed if the image of a target vehicle is repeatedly captured around the subject vehicle within a preset mileage range.

8. The vehicle security method according to claim 6, wherein the security and surveillance module comprises a reckless driver identification module that conducts focusing on the image of a target vehicle and then, based on the target vehicle'"'"'s focal length, speed, and out of focus or not, determines if the target vehicle is driven by a reckless driver.
