Next, an operation process of the vehicle navigation system according to an embodiment of the present invention having the above configuration will be described.

5 is an operation process diagram according to the route guidance in the vehicle navigation system according to an embodiment of the present invention.

When the user selects a menu according to the vehicle route guidance through a button provided on the front board 203, the selection signal is input to the key control unit 230 inside the main board 227 through the interface board 206.

The key controller 230 recognizes the input signal and informs the central processing unit 236 that the user requests the vehicle route guidance. The CPU 236 then controls the vehicle route guidance control required by the user to be performed (operation 300).

The GPS 218 receives information according to the current position of the vehicle and various traffic information required to reach the destination from the starting point to the destination through the antenna 212 under the control of the central processing unit 236. The central processing unit 236 tracks the driving trajectory by grasping the current position and the moving direction of the vehicle based on the GPS signal received from the GPS 218. In operation 302, the driving route from the starting point input by the user to the destination is searched. The basic information of the search for the driving route to the destination in the step 302 may be obtained by the information previously stored in the memory 239 or by receiving the information provided from the vehicle information center 110.

 In operation 303, a path corresponding to the shortest path is selected from the found driving paths. The selected shortest path information is temporarily stored until the destination is reached. The step 303 may be determined based on a user selection or a predetermined reference value (distance) among various search paths. At this time, in the case of user selection, it is possible to select a waypoint or a corresponding road.

The CPU 236 starts the route guidance to the searched destination in step 303 (step 306). First, the map information corresponding to the shortest path among the searched paths is read from the memory 239, and the driving path map information including the current position of the vehicle is displayed on the TFT LCD 200.

At this time, when the user requests the search signal of the step 306 by voice, the CPU 236 outputs the search path selected in the step 306 to the audio board 242. The audio board 242 inputs the input signal through the signal processor 248 and outputs it through the amplifier 269 under the control of the microcomputer 254. In this way, the user listens to the search path by voice. In this case, the signal processing unit 248 should be provided with a voice demodulation function for converting the search path into voice.

On the other hand, the central processing unit 236, while guiding the route to the destination in step 306, continues receiving the position signal of the current vehicle through the GPS module 218, and interprets the received GPS signal Judging by The determination of the current position of the host vehicle is performed to monitor whether the vehicle has reached the destination in operation 309.

The route guidance of step 306 is maintained until the vehicle arrives at the destination by the determination of step 309. If it is determined in step 309 that the vehicle has reached the destination, the CPU 236 outputs a signal for notifying the user of the destination arrival (step 312). In step 312, the audio board 242 notifies the arrival of a voice signal or outputs a signal indicating that the image arrived on the TFT LCD (200).

Meanwhile, after the CPU 236 arrives at the destination in step 312, the CPU 236 monitors whether the user requests additional information about the destination. That is, the CPU 236 outputs a signal for confirming whether the user has recognized the destination after the operation 312 (operation 315). Accordingly, in step 315, the user determines a request for additional information about the destination. If there is no request for additional information after the user arrives at the destination in step 312, the control operation is terminated in step 312 while the user shuts down the system.

However, if it is determined in step 315 that the user did not recognize the destination, the CPU 236 provides the surrounding detailed information for recognizing the destination (step 318). In step 318, the entrance / exit, the parking lot, the number of floors, additional facilities, adjacent buildings, convenience facilities, etc., provide map information that is accurately revealed. The map information is displayed on the TFT LCD 200. The map information may be data stored in the memory 239, data stored in an external storage medium, or on-line data provided in real time from the vehicle information center 110. That is, in step 315, the detailed information on the destination building provides information enough to visually identify the strange destination.

If it is determined in step 315 that the user has recognized the destination, the CPU 236 provides detailed information inside the destination (step 321). For example, when a user visits a government office, it may be possible to provide detailed information about the reduced state of the office, the internal structure of each floor, facilities, and the store. The information provided in step 321 may also be data stored in the memory 239, data stored in an external storage medium, or on-line data provided in real time from the vehicle information center 110.

The information provided in step 321 may be provided as an image on the TFT LCD 200 or may be output as audio using an external amplifier 269 (step 324).

That is, the present invention, when receiving the route information to the destination by using a vehicle information terminal such as a vehicle navigation system, after confirming whether the destination reached by the location tracking, when reaching the destination, when receiving the confirmation signal for the destination arrival There is a feature to printing. In addition, the present invention is characterized in that it is possible to sufficiently determine the destination of the first visit by checking whether the user has recognized the destination and providing detailed information on the destination.

In the above description, the vehicle navigation system is described as an embodiment of the present invention, but the present invention is not limited thereto. That is, the control of the present invention is sufficiently possible in a portable device capable of providing traffic information, such as a recent portable PDA.

For example, when the portable PDA is equipped with a GPS module for location tracking using a GPS signal or a CDMA module for location tracking using a mobile communication signal, the implementation of the present invention will be sufficiently possible. Of course, in the case of a portable PDA, since the internal and external memory is small, it is preferable to configure the portable PDA so as to receive necessary information only through a wireless network (mobile communication network or GPS satellite).
