1 is a view showing the internal structure of a vehicle navigation system for performing a function in an embodiment of the present invention.

Referring to FIG. 1, the vehicle navigation system may include a global positioning system (GPS) receiver 111, an azimuth sensor 113, and a distance sensor 115. And a positioning unit 117, a MAP information matching unit 119, a memory 121, a controller 123, a key input unit 125, an audio processing unit 127, And a display unit 129.

First, the GPS receiver 111 receives information from a GPS satellite through an antenna and outputs the received GPS satellite information to the location determiner 117. Here, the GPS satellite information may be information according to driving state of the vehicle, that is, information for determining azimuth and speed information. The azimuth sensor 113 is mounted at a location of the vehicle and senses an azimuth angle according to the vehicle driving when the vehicle is driven and outputs the azimuth angle to the positioning unit 117. Here, the azimuth sensor 113 may be a gyro sensor or the like. Similarly to the azimuth sensor 113, the distance sensor 115 is also mounted in the right place of the vehicle and senses a moving distance according to the vehicle driving while driving the vehicle and outputs the detected distance to the positioning unit 117.

The position determiner 117 inputs GPS satellite information output from the GPS receiver 111, an azimuth angle output from the azimuth sensor 113, and a moving distance output from the distance sensor 115 to present the vehicle. The position is detected, and the detected current position of the vehicle is output to the MAP information matching unit 119. Here, since the operation of detecting the current position of the vehicle by the positioning unit 117 is not directly related to the present invention, a detailed description thereof will be omitted. The MAP information matching unit 119 inputs the current position information of the vehicle output from the position determining unit 117 and accurately converts the current position of the vehicle into MAP information using the MAP information stored in the memory 121. After matching, the control unit 123 outputs the matching result.

The memory 121 stores the MAP information, and may be implemented in a flash memory form. Accordingly, the MAP information may be updated in real time under the control of the controller 123.

The key input unit 125 includes a plurality of keys, and in particular, keys for setting an operation mode of the vehicle navigation system. The audio processor 127 audio-processes and outputs voice guidance related to road information mapped to MAP information provided by the MAP information matching unit 119 under the control of the controller 123. The display unit 129 is a liquid crystal display unit (LCD) in the form of a touch screen, which is mapped to MAP information provided by the MAP information matching unit 119 under the control of the controller 123. The road information is displayed, and the coordinate value of the point touched by the user is output to the controller 123. The controller 123 controls the overall operation of the vehicle navigation system. In particular, in the embodiment of the present invention, the controller 123 controls the screen scrolling speed according to the screen position or the screen selection time.

In FIG. 1, an internal structure of a vehicle navigation system for performing a function in an embodiment of the present invention has been described. Next, an operation process of a vehicle navigation system according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3. This will be described.

2 is a diagram illustrating an example of a method of providing a screen scroll speed according to a position selected on a screen of a vehicle navigation system according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the screen displayed on the display unit 129 according to the present invention includes three areas. The regions may be divided into a circle or a quadrangle in an arbitrary distance unit as shown in FIG. 2 while going outward at the center of the center (0,0). 2 illustrates a case where an area is configured in the shape of a rectangle. A scroll speed of (X, Y) coordinates-90 dot / sec (hereinafter referred to as "first scroll speed") is given to region 1 of FIG. 2, and a (X, Y) coordinate -180 dot / Scroll speed of sec (called "second scroll speed") is given, and region 3 is given a scroll speed of (X, Y) coordinates-360 dot / sec (hereinafter referred to as "third scroll speed"). . That is, the screen scrolling speed is higher when the user touches the outside of the screen than when the user touches the center of the screen.

3 is a flowchart illustrating an operation process of a vehicle navigation system according to an exemplary embodiment of the present invention.

Referring to FIG. 3, in step 311, the controller 123 detects (X, Y) coordinates of a position selected on the screen displayed on the display unit 129, and proceeds to step 313. In step 313, the controller 123 determines whether the detected (X, Y) coordinate is area 1, area 2, or area 3. If the area of the detected (X, Y) coordinates is determined, the controller 10 assigns the determined area to the detected (X, Y) coordinate direction at the center of the screen, that is, (0,0) coordinates. The screen scrolls at the set scroll speed, and the flow proceeds to step 315. For example, if the detected coordinates (X, Y) are the first area, the screen is scrolled at the first scroll speed, the second area at the second scroll speed, and the third area at the third scroll speed.

In step 315, the controller 123 determines whether the detected (X, Y) coordinates are continuously input for a predetermined time or more, and determines whether the (X, Y) coordinates are pressed for a predetermined time or more. Proceed to step 317.

In step 317, if the controller 10 is pressed for more than the preset time, the controller 10 scrolls the screen by increasing the scroll speed by one step. For example, when the user first touches the first area, the user scrolls the screen at the first scrolling speed, and if the user keeps pressing for a predetermined time after the touch, the user scrolls the screening at the second scrolling speed. If the detected (X, Y) coordinates are continuously pressed for more than a predetermined time even after the screen scrolling starts at the second scroll speed, the screen is scrolled at the third scroll speed by increasing the scroll speed. When the first area is touched and the touched point is continuously pressed for a predetermined time, the screen scroll speed may be increased from the second scroll speed to the third scroll speed.

The screen is divided into three areas, but may be divided into three or more areas.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

The present invention as described above has the advantage that the user convenience is increased by controlling the screen scrolling speed in accordance with the screen position or screen selection time in a vehicle navigation system.
