Abstract

Provided are a system and method for a safe taxi service. The method for a safe taxi service in a mobile device includes: transmitting input information regarding a destination to a vehicle information system; periodically receiving information regarding a current location of a vehicle from the vehicle information system; comparing the current location with an expected path to the destination; and transmitting state information to an external system when it is determined, according to the comparing, that the current location deviates from the expected path to the destination to an extent equal to or greater than a predetermined limit.

Claims

1. A method for a safe taxi service in a mobile device, the method comprising:

transmitting, to a vehicle information system, input information regarding a destination;

periodically receiving, from the vehicle information system, information regarding a current location of a vehicle;

comparing the current location with an expected path to the destination; and

transmitting, to an external system, state information when it is determined, according to the comparing, that the current location deviates from the expected path to the destination to an extent equal to or greater than a predetermined limit.

2. The method of claim 1, further comprising receiving, from the vehicle information system, information regarding the expected path in response to the transmitting the information regarding the destination.

3. The method of claim 1, further comprising transmitting, to the vehicle information system, information regarding the expected path.

4. The method of claim 1, further comprising receiving, from the vehicle information system, information regarding the vehicle.

5. The method of claim 1, wherein the state information comprises information regarding the vehicle and information regarding the current location.

6. The method of claim 1, wherein the transmitting the state information comprises:

transmitting, to the external system, the state information at a first cycle when it is determined, according to the comparing, that the current location is in the expected path to the destination with a deviation less than the predetermined limit; and

transmitting, to the external system, the state information at a second cycle, shorter than the first cycle, when it is determined, according to the comparing, that the current location deviates from the expected path to the destination to an extent equal to or greater than the predetermined limit.

7. A computer-readable recording medium storing a program for executing a method for a safe taxi service in a mobile device, the method comprising:

transmitting, to a vehicle information system, input information regarding a destination;

periodically receiving, from the vehicle information system, information regarding a current location of a vehicle;

comparing the current location with an expected path to the destination;

transmitting, to an external system, state information when it is determined, according to the comparing, that the current location deviates from the expected path to the destination to an extent equal to or greater than a predetermined limit.

8. A method for a safe taxi service in a vehicle information system, the method comprising:

receiving, from a mobile device, information regarding a destination;

searching for an expected path to the destination and transmitting, to the mobile device, information regarding the searched expected path; and

periodically transmitting, to the mobile device, information regarding a current location of a vehicle.

9. The method of claim 8, further comprising transmitting, to the mobile device, information regarding the vehicle.

10. A computer-readable recording medium storing a program for executing a method for a safe taxi service in a vehicle information system, the method comprising:

receiving, from a mobile device, information regarding a destination;

searching for an expected path to the destination and transmitting, to the mobile device, information regarding the searched expected path; and

periodically transmitting, to the mobile device, information regarding a current location of a vehicle.

11. A mobile device providing a safe taxi service, the mobile device comprising:

a first communication unit which communicates with a vehicle information system;

a second communication unit which communicates with an external system; and

a path tracking unit which transmits, to the vehicle information system through the first communication unit, information regarding a destination, periodically receives, from the vehicle information system, information regarding a current location of a vehicle, compares the current location with an expected path to the destination, and transmits, to the external system through the second communication unit, state information when it is determined, according to the comparing, that the current location deviates from the expected path to the destination to an extent equal to or greater than a predetermined limit.

12. The mobile device of claim 11, wherein the path tracking unit receives, from the vehicle information system, information regarding the expected path to the destination in response to the transmission of the information regarding the destination.

13. The mobile device of claim 11, further comprising:

a navigation unit which allows a user to select a preferred path to the destination,

wherein the path tracking unit transmits, to the vehicle information system, information regarding the selected preferred path as information regarding the expected path to the destination.

14. The mobile device of claim 11, wherein the path tracking unit receives, from the vehicle information system, information regarding the vehicle.

15. The mobile device of claim 11, wherein the state information comprises information regarding the vehicle and information regarding the current location.

16. The mobile device of claim 11, wherein the path tracking unit transmits, to the external system, the state information at a first cycle when it is determined, according to the comparing, that the current location is in the expected path to the destination with a deviation less than the predetermined limit, and transmits, to the external system, the state information at a second cycle, shorter than the first cycle, when it is determined, according to the comparing, that the current location deviates from the expected path to the destination to an extent equal to or greater than the predetermined limit.

17. The mobile device of claim 11, wherein the first communication unit comprises a local area communication module.

18. A vehicle information system providing a safe taxi service, the vehicle information system comprising:

a communication unit which communicates with a mobile device;

a navigation unit which searches for an expected path to a destination;

a location determination unit which acquires information regarding a current location of a vehicle; and

a vehicle information management unit which receives, from the mobile device through the communication unit, information regarding a destination, transmits, to the mobile device, information regarding the expected path to the destination, searched by the navigation unit, and periodically transmits, to the mobile device, the information regarding the current location of the vehicle.

19. The vehicle information system of claim 18, wherein the vehicle information management unit transmits, to the mobile device, information regarding the vehicle.

20. The vehicle information system of claim 18, wherein the communication unit comprises a local area communication module.
