Abstract

Provided is a system for verifying a vehicle-based communication service through simulation based on various environments. The system includes a first terminal configured to receive log data and output data from a vehicle terminal equipped in each of a plurality of vehicles, transmit the log data and a reproduction command signal corresponding to the log data, and display the output data and a second terminal configured to receive the log data from the first terminal to upload the log data, perform synchronization of a corresponding system time, and adjust a reproduction time of each of pieces of log data to a predetermined reference point according to the reproduction command signal.

Claims

1. A system for verifying a vehicle-based communication service, the system comprising:

a first terminal configured to receive log data and output data from a vehicle terminal equipped in each of a plurality of vehicles, transmit the log data and a reproduction command signal corresponding to the log data, and display the output data; and

a second terminal configured to receive the log data from the first terminal to upload the log data, perform synchronization of a corresponding system time, and adjust a reproduction time of each of pieces of log data to a predetermined reference point according to the reproduction command signal.

2. The system of claim 1, wherein the first terminal receives, as the output data, vehicle-to-vehicle communication middleware and data associated with a safety service from the vehicle terminal.

3. The system of claim 1, wherein the first terminal is a Windows personal computer and uploads, through an FTP server, the received log data to the second terminal that is a Linux personal computer.

4. The system of claim 1, wherein the second terminal performs synchronization of a system time by using an embedded NTP server.

5. The system of claim 1, wherein, with respect to log data having a latest logging start time among pieces of log data received from the first terminal, the second terminal identically adjusts reproduction times of the pieces of log data according to a predetermined method.

6. The system of claim 5, wherein the second terminal identically adjusts the reproduction times of the pieces of log data to an initial value, corresponding to a predetermined multiple of reproduction time, with respect to a logging start time of the log data having the latest logging start time.

7. The system of claim 6, wherein the second terminal transmits reproduced data to the vehicle terminal, and the vehicle terminal transmits middleware and the output data, which is data associated with a safety service, to the first terminal according to the reproduced data being received.

8. The system of claim 7, wherein

the first terminal comprises a display unit configured to display the output data, and

the display unit displays, to a user, a result value based on the output data by using a simulation tool.

9. The system of claim 8, wherein the display unit displays a setup tab which displays setup information including an IP address and a port number, a map information tap, and a vehicle information tap.

10. The system of claim 9, wherein

the setup tab comprises a command button for transmitting logging data to the second terminal, and

the setup tab receives numbers of logging files as data numbers and receives control information for controlling a whole system.

11. The system of claim 9, wherein the vehicle information tab comprises at least one of a tab that displays a current vehicle position, a route history, and an expectation route, a tab that displays information of peripheral vehicles received through WAVE communication, and a tab that displays position information of a tracked vehicle around a vehicle.

12. The system of claim 9, wherein the vehicle information tab displays position information of a vehicle, from which a warning message based on a safety service is generated, and a result value signal associated with the safety service.
