Abstract

A burglar proof system for a vehicle is provided. The burglar proof system includes a portable burglar proof device and an observation device disposed on the vehicle. The portable burglar proof device receives remote key information from a server, which includes an input unit for the user, and an operation unit produces a first value according to the remote key information and information inputted by the user. The observation device includes a validation unit and a control unit. The validation unit produces a second value according to the first value and local key information, and compares the first and second values. The control unit enables control of the engine of the vehicle when the second value is equivalent to the validation information. The disclosure further provides an observation device for the burglar proof system.

Claims

1. A burglar proof system for a vehicle, the burglar proof system comprising:

a portable burglar proof device comprising;

a wireless communication unit receiving remote key information;

an input unit inputting input information; and

an operation unit using a first algorithm to produce a first value according to the remote key information and the input information; and

an observation device disposed on the vehicle, the observation device comprising;

a validation unit using a second algorithm to produce a second value according to the first value and local key information, and comparing the second value with validation information; and

a control unit enabling an engine controller of the vehicle to operate an engine of the vehicle when the second value corresponds to the validation information.

2. The burglar proof system of claim 1, wherein the portable burglar proof device comprises a location identification unit producing location information of the portable burglar proof device.

3. The burglar proof system of claim 2, wherein the observation device transmits a warning message to the portable burglar proof device when the second value not corresponds to the validation information, the portable burglar proof device transmits one or more location messages comprising the location information to a server through the wireless communication unit in response to receiving the warning message.

4. The burglar proof system of claim 2, wherein the remote key information comprises a reserved word, the portable burglar proof device comprises a control unit determining the presence of the reserved word in the remote key information and transmits the one or more location messages comprising the location information to the server through the wireless communication unit when the reserved word is found in the remote key information.

5. The burglar proof system of claim 1, wherein the portable burglar proof device comprises a storage unit storing the remote key information, the remote key information in the storage unit is deleted in a predetermined time period after the first value is produced.

6. The burglar proof system of claim 1, wherein the portable burglar proof device comprises a storage unit storing the remote key information, the remote key information in the storage unit is deleted immediately after the first value is produced.

7. The burglar proof system of claim 1, wherein the first algorithm comprises at least one of a mathematical operation and a logical operation on the remote key information and the input information, the second algorithm comprise at least one of a mathematical operation and a logical operation on the first value and the local key information.

8. The burglar proof system of claim 1, further comprising a server producing the remote key information according to a first time, wherein the wireless communication unit of the portable burglar proof device receives the remote key information from the server.

9. The burglar proof system of claim 7, wherein the local key information comprises a second time, the validation unit of the observation device produces the validation information according to the second time.

10. An observation device disposed on a vehicle, the observation device comprising:

a communication unit receiving a first value from a portable burglar proof device with a wireless communication unit;

a validation unit using a second algorithm to produce a second value according to the first value and local key information, and comparing the second value with validation information; and

a control unit enabling an engine controller of the vehicle to operate an engine of the vehicle when the second value corresponds to the validation information.

11. The observation device of claim 10, wherein the first value is produced using a first algorithm according to remote key information and input information in the portable burglar proof device, the remote key information is received through the wireless communication unit of the portable burglar proof device.

12. The observation device of claim 10, wherein when the second value not corresponds to the validation information, the observation device transmits a warning message to the portable burglar proof device to enable the portable burglar proof device to transmit one or more location messages comprising location information of the portable burglar proof device to a server through the wireless communication unit of the portable burglar proof device in response to receiving the warning message.

13. The observation device of claim 10, wherein the second algorithm comprise at least one of a mathematical operation and a logical operation on the first value and the local key information.
