Abstract

A method for finding an object coupled to a radio transmitter, wherein the radio transmitter emits an assigned identifier. The method includes transmitting a first message to at least a first vehicle by a data processing system, wherein the message contains the information that a specific identifier is being searched for; forwarding the first message to at least a second vehicle by the first vehicle; receiving and comparing the assigned identifier with the specific identifier by a vehicle which received the first message; and, if the assigned identifier corresponds to the specific identifier, transmitting a second message by the vehicle which received the assigned identifier to the data processing system. The second message contains information that the specific identifier has been found and information about a position of the vehicle which received the assigned identifier.

Claims

1. A method for locating a target transportation vehicle coupled to a radio transmitter, wherein the radio transmitter emits an assigned identifier associated with the target transportation vehicle, the method comprising:

transmitting a first message to at least a first transportation vehicle by a data processing system, wherein the first message contains information that a specific identifier is being searched for;

forwarding the first message to at least a second transportation vehicle by the first transportation vehicle;

receiving and comparing the first message with the receiving vehicle'"'"'s identifier, the receiving vehicle being any one of the first, second, or target transportation vehicles; and

in response to the receiving vehicle'"'"'s identifier corresponding to the specific identifier such that the target vehicle has been located;

transmitting a second message by the target transportation vehicle to the data processing system;

or

transmitting the second message by the target transportation vehicle to one or more of the first, second, or another transportation vehicle for forwarding to the data processing system,

wherein the second message contains information indicating that the specific identifier has been found and information indicating the location of the target transportation vehicle and/or information about a distance which the target transportation vehicle has traveled between reception of the first message and transmission of the second message.

2. The method of claim 1, further comprising:

in response to receipt of the second message by the other transportation vehicle which received the first message;

generating a third message that contains the second message and information about a location of the other transportation vehicle; and

one of;

transmitting the third message to the data processing system;

or

transmitting the third message to another transportation vehicle which received the first message, for forwarding to the data processing system.

3. The method of claim 1, wherein the first message is transmitted over a cellular network or over a wireless local network.

4. The method of claim 1, wherein the first message is forwarded wirelessly at a frequency of less than 500 MHz, and/or wherein the second message is transmitted to the other vehicle wirelessly at a frequency of less than 500 MHz.

5. The method of claim 1, wherein the radio transmitter emits the assigned identifier only in response to a detection circuit coupled to the radio transmitter detecting an unauthorized use of the target transportation vehicle.

6. The method of claim 1, wherein the second message contains only a position of one the transportation vehicles which received the assigned identifier without further identification of that transportation vehicle.

7. The method of claim 1, further comprising transmitting a search request to the data processing system by a mobile device.

8. A method for locating a target transportation vehicle coupled to a radio transmitter, wherein the radio transmitter emits an assigned identifier linked with the target transportation vehicle, the method comprising:

transmitting a first message to at least a first transportation vehicle by a data processing system, wherein the first message contains an order to signal a received identifier;

forwarding the first message to at least a second transportation vehicle by the first transportation vehicle;

receiving and comparing the received identifier ordered in the first message by the first, second, or another transportation vehicle which received the first message with the receiving vehicle'"'"'s assigned identifier; and

in response to the receiving vehicle'"'"'s assigned identifier corresponding to the received identifier ordered in the first message, transmitting a second message indicating that the assigned identifier linked with the target transportation vehicle has been located;

to the data processing system by the receiving vehicle as the target transportation vehicle;

or to any other transportation vehicle for forwarding to the data processing system,

wherein the second message contains the information that the assigned identifier linked with the target transportation vehicle has been located, and information about a location of the target transportation vehicle and/or information about a distance which the target transportation vehicle has traveled between the reception of the first message and the transmission of the second message.

9. The method of claim 8, further comprising:

in response to receipt of the second message by the other transportation vehicle which received the first message;

generating a third message that contains the second message and information about a location of the other transportation vehicle; and

one of;

transmitting the third message to the data processing system;

or

transmitting the third message to another transportation vehicle which received the first message, for forwarding to the data processing system.

10. The method of claim 8, wherein the first message is transmitted over a cellular network or over a wireless local network.

11. The method of claim 8, wherein the first message is forwarded wirelessly at a frequency of less than 500 MHz, and/or wherein the second message is transmitted to the other vehicle wirelessly at a frequency of less than 500 MHz.

12. The method of claim 8, wherein the radio transmitter emits the assigned identifier only in response to a detection circuit coupled to the radio transmitter detecting an unauthorized use of the target transportation vehicle.

13. The method of claim 8, wherein the second message contains only a position of one the transportation vehicles which received the assigned identifier without further identification of that transportation vehicle.

14. The method of claim 8, further comprising transmitting a search request to the data processing system by a mobile device.

15. A method for finding a target transportation vehicle coupled to a radio transmitter, the method comprising:
