Abstract

An adverse situation warning device includes a route data storing portion for storing a first route data of a host vehicle including a first geohash corresponding to a moving route of the host vehicle, a route comparing portion for receiving a second route data of a remote vehicle including a second geohash corresponding to a moving route of the remote vehicle, and for comparing the geohash of the first route data and the geohash of the second route data, and a warning output portion for outputting an adverse situation warning based on the comparison result.

Claims

1. An adverse situation warning device, comprising:

a computer;

a route data storing portion of the computer for storing a first route data of a host vehicle including a first geohash corresponding to a moving route of the host vehicle;

a route comparing portion of the computer for receiving a second route data of a remote vehicle including a second geohash corresponding to a moving route of the remote vehicle, and for comparing the geohash of the first route data and the geohash of the second route data; and

a warning output portion of the computer for outputting an adverse situation warning when the comparison result indicates the host vehicle and the remote vehicle are travelling in a similar direction,

wherein the route comparing portion compares a string of the geohash of the first route data and a string order of the geohash of the first route data with a string of the geohash of the second route data and a string order of the geohash of the second route data.

2. The adverse situation warning device of claim 1, wherein the route comparing portion receives the second route data from a remote server.

3. The adverse situation warning device of claim 2, wherein the route comparing portion monitors route data stored in the server through connection pooling.

4. The adverse situation warning device of claim 1, further comprising:

a global positioning system (GPS) receiver for receiving at least one GPS signal and calculating a position coordinate of the host vehicle; and

a geohash converter for converting the position coordinate of the host vehicle into the geohash to generate the first route data.

5. The adverse situation warning device of claim 2, further comprising:

a control system for generating a danger signal for informing of an adverse situation of the host vehicle; and

an adverse situation detector for transmitting an adverse situation occurrence binary signal, the generated danger signal and the first route data to the server in response to the generation of the danger signal.

6. The adverse situation warning device of claim 5, wherein the danger signal includes at least one of an airbag deployment signal, a sudden stop signal, a sudden deceleration signal and a crash signal.

7. The adverse situation warning device of claim 5, wherein the warning output portion receives the danger signal of the remote vehicle from the server, calculates degree of risk based on the danger signal and outputs a warning based on the calculated result of the degree of risk.

8. A non-transitory computer readable recording medium which records program instructions on a computer for executing an adverse situation warning method through an adverse situation warning device, the computer readable recording medium comprising:

program instructions for storing a first route data of a host vehicle including a geohash corresponding to a moving route of the host vehicle;

program instructions for monitoring a route data stored in a server;

program instructions for receiving a second route data including a geohash corresponding to a moving route of a remote vehicle in an adverse situation from the server;

program instructions for comparing a string of the geohash of the first route data and a string order of the geohash of the first route data with a string of the geohash of the second route data and a string order of the geohash of the second route data; and

program instructions for outputting an adverse situation warning when the comparison result indicates the host vehicle and the remote vehicle are travelling in a similar direction,

wherein the non-transitory computer readable recording medium includes at least one of ROM, RAM, CD-ROM, a magnetic tape, a floppy disk and an optical recording medium.

9. The computer readable recording medium of claim 8, wherein the program instructions for monitoring a route data stored in a server, when executed, monitors the route data stored in the server through connection pooling.

10. The computer readable recording medium of claim 8, further comprising:

program instructions for receiving at least one GPS signal;

program instructions for calculating a position coordinate of the host vehicle based on the received GPS signal; and

program instructions for generating and updating the first route data by converting the calculated position coordinate into the geohash.

11. The computer readable recording medium of claim 8, further comprising:

program instructions for generating a danger signal informing of an adverse situation of the host vehicle; and

program instructions for transmitting an adverse situation occurrence binary signal, the generated danger signal and the first route data to the server in response to the generation of the danger signal.

12. The computer readable recording medium of claim 11, wherein the danger signal includes at least one of an airbag deployment signal, a sudden stop signal, a sudden deceleration signal and a crash signal.

13. The computer readable recording medium of claim 11, wherein the program instructions for outputting an adverse situation warning, when executed, receives the danger signal of the remote vehicle, calculates degree of risk based on the danger signal, and outputs a warning based on the calculated result of the degree of risk.
