Anti theft system
View Patent ↗A method for identifying the position of a stolen vehicle is provided that includes the steps of detecting the start of an engine of the vehicle, retrieving vehicle identification information, establishing a connection to an external database of stolen vehicles, transmitting the retrieved vehicle identification information via a wireless communication system to the database and verifying whether the identified vehicle is in the database of stolen vehicles. If the identified vehicle is in the list of stolen vehicles, the position of the vehicle is then determined.
1. A method for identifying a stolen vehicle, the method comprising the steps of:
detecting the start of an engine of the vehicle;
retrieving a vehicle identification information automatically when the engine is started;
establishing a connection from a network access device in a hands free unit to an external database of stolen vehicles,
where, when the hands free unit is connected to a mobile communications unit operable as a cell phone, the hands free unit is configured to obtain subscriber information from the mobile communication unit, to establish a subscriber connection over a mobile telephony network utilizing the subscriber information in accordance with a mobile telephony service corresponding to the subscriber information; and
where, when the bands free unit is not connected to the mobile communication unit in order to receive subscriber information for communicating over the mobile telephony network using subscriber information in accordance with the mobile telephony service corresponding to the subscriber information, the hands flee unit is configured to establish the connection to the external database of stolen, vehicles without the subscriber information;
transmitting the retrieved vehicle identification information via the mobile telephony network to the external database of stolen vehicles;
determining whether the identified vehicle is in the database of stolen vehicles.
2. The method of claim 1 further comprising the step of determining the position of the vehicle if the identified vehicle is in the database of stolen vehicles.
3. The method of claim 2 , where the position of the vehicle is determined outside the vehicle based on the transmitted vehicle identification information signal.
4. The method of claim 2 , where the position of the vehicle is determined based on cell information of the mobile telephony network.
5. The method of claim 2 , where the position of the vehicle is determined based on a satellite radio signal.
6. The method of claim 1 , further comprising the step of stopping fine vehicle fuel supply to the engine if the identified vehicle is determined to be in the list of stolen vehicles.
7. The method of claim 2 , further comprising the step of transmitting the position of vehicle to a responsible authority.
8. The method of claim 1 , where, if the identified vehicle is determined to be in the list of stolen vehicles, at least one of the following activities is initiated: fine vehicle engine is cut off, a horn of the vehicle is activated, a photo of a passenger compartment of the vehicle is taken.
9. A method for identifying a stolen vehicle, the method comprising the steps of:
retrieving information relating to a vehicle identity at the start-up of the vehicle;
establishing a connection with a server for accessing a database of stolen vehicles over a mobile telephony network initiated from a network access device in a hands free unit configured to provide subscriber communications over a mobile telephony network when connected to a mobile phone communication unit having a means for identifying the subscriber of the mobile telephony service provided by the mobile telephony network, where the connection to the server for accessing a database of stolen vehicles is established even when the means for identifying the subscriber cannot be retrieved from the mobile communication phone unit and the hands free unit is not able to connect in accordance with the mobile telephony service;
transferring the retrieved information to the server for accessing a database of stolen vehicles;
determining whether the vehicle is a stolen vehicle by comparing the transferred information with the database of stolen vehicles accessible by the server; and determining the position of the vehicle.
10. The method of claim 9 , where the means for identifying a subscriber are a subscriber identity module card.
11. A vehicle anti theft system comprising:
a detector detecting the start of the engine of the vehicle;
a hands free unit having a network access device and configured to provide subscriber communications over a mobile telephony network when connected to a mobile communication unit operable as a cell phone and having subscriber identification information for mobile telephony service over the mobile telephony network, and configured to enable the transfer of vehicle identification information via the mobile telephony network even if no subscriber identification information is available and the hands free unit is not able to connect in accordance with the mobile telephony service;
a vehicle identification unit automatically retrieving vehicle identification information when the engine is started; and
a transmitter transmitting the vehicle identification information to an external database of stolen vehicles via the mobile telephony network.
12. The vehicle anti theft system of claim 11 further comprising a position detecting unit which, upon detecting that the vehicle is recognized as a stolen vehicle, determines the position of the vehicle.
13. The vehicle ante theft system of claim 12 , where the position detecting unit is located outside the vehicle.
14. The vehicle anti theft system of claim 12 , where the position detecting unit determines the position of the vehicle based on the cell information of the mobile telephony network.
15. The vehicle anti theft system of claim 11 , where the database of stolen vehicles is provided on a server accessible over the mobile telephony network.
16. The vehicle anti theft system of claim 11 , further comprising an engine control unit which, upon detection that the vehicle is stolen, interrupts the functioning of the vehicle engine.
17. A vehicle anti theft system comprising:
a detector detecting the start of the engine of the vehicle;
a vehicle identification unit automatically retrieving a vehicle identification information when the engine is started;
a hands flee unit having a network access device and configured to provide subscriber communications over a mobile telephony network when connected to a mobile phone communication unit having subscriber identification information in accordance with a mobile telephony service corresponding to the subscriber information, and configured to enable the transfer of vehicle identification information via the mobile telephony network even if no subscriber identification information is available and the hands free unit is not able to connect in accordance with the mobile telephony service;
a transmitter transmitting the vehicle identification information to an external database of stolen vehicles via the mobile telephony network; and
a position detecting unit which, upon detecting that the vehicle is recognized as a stolen vehicle, determines the position of the vehicle.
