Abstract

A Head-Up Display (HUD) navigation system, a head-up display navigation device, and a method for implementing an HUD service are provided. The HUD navigation system includes a server, a mobile terminal, and an HUD navigation device. The server generates GPS route data using departure point data, destination data, and previously stored road information data. The mobile terminal requests the server to generate GPS route data and provides GPS route data transmitted from the server. The HUD navigation device compares the GPS route data provided from the mobile terminal with current GPS position data to generate navigation data and projects at least one of a horizontally mirrored image, a horizontally mirrored character, or a horizontally mirrored numeric value corresponding to at least part of the navigation data onto a windshield.

Claims

1. A head-up display navigation device comprising:

a data generating unit that generates navigation data by comparing current GPS position data with GPS route data provided from an external device; and

a light source unit that projects at least one of a horizontally mirrored image, a horizontally mirrored character, or a horizontally mirrored numeric value corresponding to at least part of the navigation data onto a windshield.

2. The head-up display navigation device according to claim 1, further comprising an output unit that reproduces a sound corresponding to at least part of the navigation data.

3. The head-up display navigation device according to claim 1, wherein the current GPS position data is provided from an external device.

4. The head-up display navigation device according to claim 1, further comprising a GPS receiver that receives the current GPS position data.

5. The head-up display navigation device according to claim 1, wherein the data generating unit compares the GPS route data with the current GPS position data to determine whether or not route deviation has occurred and generates a route re-search message including the current GPS position data upon determining that route deviation has occurred.

6. The head-up display navigation device according to claim 1, wherein the light source unit comprising:

a first light source module that is a dot-matrix type and projects the horizontally mirrored image;

a second light source module that is of a dot-matrix type and projects the horizontally mirrored character; and

a third light source module that is of a 7-segment type and projects the horizontally mirrored numeric value.

7. The head-up display navigation device according to claim 1, further comprising an external display unit that displays at least one of an image, a character, and a numeric value corresponding to at least part of the navigation data.

8. A head-up display navigation system comprising:

a server that generates GPS route data using departure point data, destination data, and previously stored road information data;

a mobile terminal that requests the server to generate the GPS route data and provides the GPS route data transmitted from the server to a head-up display navigation device; and

the head-up display navigation device that compares the GPS route data provided from the mobile terminal with current GPS position data to generate navigation data and projects at least one of a horizontally mirrored image, a horizontally mirrored character, or a horizontally mirrored numeric value corresponding to at least part of the navigation data onto a windshield.

9. The head-up display navigation system according to claim 8, wherein the head-up display navigation device compares the current GPS position data with the GPS route data to determine whether or not route deviation has occurred and provides a route re-search message including the current GPS position data to the mobile terminal upon determining that route deviation has occurred, and

the mobile terminal transmits the current GPS position data included in the re-search message as new departure point data to the server.

10. The head-up display navigation system according to claim 8, wherein the mobile terminal wirelessly receives updated content data from the server, and

the head-up display navigation device projects an image, a numeric value, or text corresponding to at least part of the content data provided from the mobile terminal.

11. The head-up display navigation system according to claim 8, wherein the head-up display navigation device processes at least part of data generated by an Electronic Control Unit (ECU) provided in a vehicle and additionally projects at least one of a horizontally mirrored image, a horizontally mirrored character, or a horizontally mirrored numeric value onto a windshield.

12. The head-up display navigation system according to claim 11, wherein the head-up display navigation device receives ECU data analyzed by an ECU data analyzer and converts the received data into at least one of a horizontally mirrored image, a horizontally mirrored character, or a horizontally mirrored numeric value and projects the converted data onto the windshield.

13. A method for implementing a head-up display navigation service, the method comprising:

comparing current GPS position data with GPS route data provided from an external device to generate navigation data; and

projecting at least one of a horizontally mirrored image, a horizontally mirrored character, or a horizontally mirrored numeric value corresponding to at least part of the navigation data onto a windshield.

14. The head-up display navigation system according to claim 13, further comprising:

comparing the GPS route data with the current GPS position data to determine whether or not route deviation has occurred and providing a route re-search message including the current GPS position data to the external device upon determining that route deviation has occurred.
