Abstract

A method and a system for vehicle surveillance are provided. The vehicle surveillance system integrates a global position system (GPS) and a vehicle recorder. The geographic coordinate of the current parking position is obtained by the GPS system. The vehicle surveillance system is turned off if the vehicle surveillance system is outside a predetermined radius of geographic coordinates of pre-saved non-safe parking positions. The activation of the vehicle surveillance system is maintained such that the vehicle is surveilled and its surrounding images are recorded in a selective and continuous manner if the vehicle surveillance system is within a predetermined radius of the geographic coordinates of non-safe parking positions.

Claims

1. A vehicle surveillance system, wherein the vehicle surveillance system is powered by a vehicle power supply and comprises:

a vehicle recorder whose ON/OFF is controlled by a micro-processing unit, wherein the vehicle recorder records and processes images around the vehicle into audio/video files cyclically saved in a storage unit, which pre-saves a geographic coordinate group of non-safe parking positions and a predetermined radius;

a global position system (GPS) linked to the vehicle recorder, wherein the GPS system is controlled by the micro-processing unit to obtain the geographic coordinate of a parking position;

a comparison unit linked to the vehicle recorder, wherein the comparison unit is controlled by the micro-processing unit to compare the geographic coordinate of the current parking position with a non-safe parking range formed by the geographic coordinate group of non-safe parking positions and a predetermined radius R which are pre-saved in the storage unit; and

a delay unit linked to the vehicle recorder, wherein the delay unit is controlled by the micro-processing unit to delay a termination of the vehicle surveillance system for a predetermined time after the vehicle power supply is turned off;

wherein, after the vehicle power supply is turned off, the micro-processing unit controls the delay unit to delay the termination of the vehicle surveillance system, controls the GPS system to obtain the geographic coordinate of the current parking position, and controls the comparison unit to compare the obtained geographic coordinate with the non-safe parking range saved in the storage unit to determine whether to maintain the activation of the vehicle surveillance system.

2. The vehicle surveillance system according to claim 1, wherein when the vehicle surveillance system is manually activated, the micro-processing unit determines the parking position as a non-safe parking position, the GPS system obtains the geographic coordinate of the current parking position, and the storage unit saves the geographic coordinate of the current parking position to the geographic coordinate group of non-safe parking positions.

3. The vehicle surveillance system according to claim 1, wherein the storage unit pre-saves the geographic coordinate group of safe parking position and a predetermined safe radius to form a safe parking range.

4. The vehicle surveillance system according to claim 3, wherein when the micro-processing unit determines that the vehicle is within the non-safe parking range, the activation of the vehicle surveillance system cannot be maintained unless the safe parking range is exclusive of the current parking position.

5. The vehicle surveillance system according to claim 1, wherein the micro-processing unit and the vehicle power supply are linked by a power surveillance device, which is controlled by the micro-processing unit to detect the capacity of the vehicle power supply.

6. The vehicle surveillance system according to claim 5, wherein the storage unit pre-saves a power-low threshold, and when the power surveillance device detects that the capacity of the vehicle power supply is smaller than the power-low threshold, the vehicle surveillance system is turned off.

7. A vehicle surveillance method, comprising:

(1) turning off the vehicle power supply when the vehicle is parked, and delaying the termination of the vehicle surveillance system for a predetermined time within which the GPS system obtains the geographic coordinate of the current parking position;

(2) determining whether the geographic coordinate of the current parking position is within a predetermined radius of a pre-saved geographic coordinate group of non-safe parking positions, and the method proceeds to step (3) if the geographic coordinate of the current parking position is within the predetermined radius of the geographic coordinate group of non-safe parking positions, and proceeds to step (4) if the geographic coordinate of the current parking position is outside the predetermined radius of the geographic coordinate group of non-safe parking positions;

(3) maintaining the activation of the vehicle surveillance system;

(4) turning off the vehicle surveillance system.

8. The vehicle surveillance method according to claim 7, wherein after it is determined that the geographic coordinate of the current parking position is outside the predetermined radius of the geographic coordinates of non-safe parking positions, whether the geographic coordinate of the current parking position is within the predetermined safe radius of the geographic coordinate group of pre-saved safe parking positions is determined, and the method proceeds to step (4) if the geographic coordinate of the current parking position is outside the predetermined safe radius of the geographic coordinate group of safe parking positions and proceeds to step (3) if the geographic coordinate of the current parking position is within the predetermined safe radius of the geographic coordinate group of safe parking positions.

9. The vehicle surveillance method according to claim 7, wherein after the activation of the vehicle surveillance system is maintained, the capacity of the vehicle power supply is detected, and whether the capacity of the vehicle power supply is lower than a predetermined power-low threshold is determined, and the capacity of the vehicle power supply is continuously detected if the capacity of the vehicle power supply is lower than the predetermined power-low threshold and the vehicle surveillance system is turned off if the capacity is lower than the predetermined power-low threshold.

10. The vehicle surveillance method according to claim 9, wherein after the vehicle surveillance system is turned off, manual activation of the vehicle surveillance system is selected.

11. The vehicle surveillance method according to claim 10, wherein the GPS system obtains the geographic coordinate of the current parking position which is saved to the geographic coordinate group of non-safe parking positions.
