The current position detection program 64c is a program for causing the CPU 61 to realize a function of detecting the current position, for example.
Specifically, the CPU 61 causes the current position detection unit 1 configured by a GPS positioning unit or the like to acquire current position information of the navigation device 100 itself, and generates a current position detection signal output from the current position detection unit 1. Based on this, the coordinates (latitude / longitude) of the navigation device 100 are detected. Further, map matching processing is performed based on the specified latitude / longitude, and the current position of the navigation device 100 is specified.
The CPU 61 functions as a current position detection unit together with the current position detection unit 1 by executing the current position detection program 64c.

The guidance information acquisition program 64d, for example, instructs the CPU 61 to guide information in the guidance mode selected by the execution of the display guidance mode selection program 64a according to the current position detected by the execution of the current position detection program 64c, This is a program for realizing the function of acquiring the guidance information in the guidance mode selected by executing the voice guidance mode selection program 64b.
The CPU 61 functions as a guidance information acquisition unit by executing the guidance information acquisition program 64d.

  Here, the guidance information acquisition process performed when the first guidance mode to the fourth guidance mode are selected in the execution of the display guidance mode selection program 64a or the voice guidance mode selection program 64b will be described.

  First, when the first guidance mode is selected in the display guidance mode selection program 64a or the voice guidance mode selection program 64b, the CPU 61 executes the current position detection program 64c while the vehicle equipped with the navigation device 100 is traveling. In addition to detecting the current position of the vehicle, the coordinates (latitude / longitude) of the node included in the node information of the road information indicate whether or not the detected current position has become a guidance information providing point in the first guidance mode. Monitor based on. Here, for example, it is assumed that the guidance information providing point in the first guidance mode is determined within a predetermined distance range (for example, within 100 m) from the intersection where the vehicle is guided. Then, when the current position is within a predetermined distance range (for example, within 100 m) from the intersection, the CPU 61 acquires the official name of the road to which the vehicle is guided from the link information of the road information.

  In addition, when the second guidance mode is selected in the display guidance mode selection program 64a or the voice guidance mode selection program 64b, the CPU 61 executes the current position detection program 64c while the vehicle is traveling to execute the current position of the host vehicle. , And whether or not the detected current position has become a guidance information provision point in the second guidance mode is monitored based on the coordinates (latitude and longitude) of the nodes included in the node information of the road information. Here, for example, as in the first guidance mode, a point within a predetermined distance range (for example, within 100 m) from the intersection where the vehicle is guided is a guidance information provision point in the second guidance mode. . Then, when the current position is within a predetermined distance range (for example, within 100 m) from the intersection, the CPU 61 acquires the common name of the road to which the vehicle is guided from the link information of the road information.

  In addition, when the third guidance mode is selected in the display guidance mode selection program 64a or the voice guidance mode selection program 64b, the CPU 61 executes the current position detection program 64c while the vehicle is traveling to execute the current position of the host vehicle. , And whether or not the detected current position is a point for providing guidance information in the third guidance mode is monitored based on the coordinates (latitude / longitude) of the tourist guidance information. Then, when the current position is a point where the tourist guide information is provided, the CPU 61 acquires the tourist guide information associated with the coordinates from the road information.

  In addition, when the fourth guidance mode is selected in the display guidance mode selection program 64a or the voice guidance mode selection program 64b, the CPU 61 executes the current position detection program 64c while the vehicle is traveling to execute the current position of the host vehicle. The map information DB 632a is searched for guidance information corresponding to the keyword input by the user, and the detected current position becomes a provision point of guidance information corresponding to the keyword input by the user in the fourth guidance mode. Whether or not the information is based on the coordinates (latitude / longitude) of the guidance information. Here, for example, a point within a predetermined distance range (for example, within 300 m) from the coordinates of the guidance information corresponding to the keyword input by the user is a guidance information provision point in the fourth guidance mode. Then, when the current position is within a predetermined distance range (for example, within 300 m) from the coordinates of the guidance information corresponding to the keyword input by the user, the CPU 61 displays the keyword guidance information associated with the coordinates on the road. Obtain from information.

The display control program 64e has a function of causing the display unit 3 to display, for example, guidance information in the guidance mode selected by the execution of the display guidance mode selection program 64a acquired by the CPU 61 by the execution of the guidance information acquisition program 64d. It is a program for realizing.
Specifically, in the execution of the above-described guidance information acquisition program 64d, according to the set guidance mode, at each provision point, the official name of the guidance destination road / common name of the road / tourist guidance information / user input When the guide information corresponding to the keyword is acquired from the road information, the CPU 61 displays the acquired guide information on the display unit 3 and provides the guide information.
The CPU 61 functions as a display control unit by executing the display control program 64e.

Here, the guidance display process in the execution of the display control program 64e will be specifically described.
For example, when the guidance mode set in the display guidance mode selection program 64a is the first guidance mode, the CPU 61 guides the vehicle in which the current position of the vehicle is the provision point of guidance information in the first guidance mode. Acquired when the official name of the road (for example, “National highway No. XX line”) is acquired from the road information by executing the guidance information acquisition program 64d within a predetermined distance range (for example, within 100 m) from the intersection to be performed. The route guidance information using the official name of the completed road is displayed on the display unit 3 to perform route guidance. In the example of FIG. 4, for example, a map symbol of the national highway XX line is displayed on the map displayed on the display unit 3 and a route such as “turn right at the next intersection. Enter the national highway XX line”. Display guidance information in text.

  Further, for example, when the guidance mode set in the display guidance mode selection program 64a is the fourth guidance mode and the keyword input by the user is “convenience store”, the CPU 61 determines that the current position of the vehicle is a convenience store. When the information about the keyword “convenience store” input by the user is acquired from the store information of the road information by executing the guide information acquisition program 64d when the store is within a predetermined range of coordinates, the acquired information Is displayed on the display unit 3 to perform keyword guidance based on guidance information that matches the keyword input by the user. In the example of FIG. 5, a mark is displayed at the position where the convenience store is located on the map displayed on the display unit 3, and “turn right at the next intersection and go straight about 100 m. The convenience store is on the left side. Keyword guidance information such as “There is” is displayed in text.

  Further, for example, when the first to fourth guidance modes are set in the display guidance mode selection program 64a and the keyword of the fourth guidance mode input by the user is “convenience store”, the CPU 61 determines the current position of the host vehicle. Becomes a provision point of guidance information in each guidance mode, and by executing the guidance information acquisition program 64d, from the road information, the official name of the road (for example, “National highway XX line”), the common name of the road (for example, "XX street"), tourist guidance information, and guidance information that matches the keyword "convenience store" entered by the user, respectively, the obtained guidance information is displayed on the display unit 3, and route guidance / tourist guidance / keywords are displayed. Give guidance. In the example of FIG. 6, for example, on the map displayed on the display unit 3, the map symbol of the national highway XX line, the display of XX street, the mark of the convenience store, and the display of the farm are displayed, respectively. Turn right at the intersection, enter National Highway XX, enter XX Street. Go straight about 100m. There is a convenience store on the left. The farm that can be seen in front of the right hand is producing local specialty △△. Display guidance information in text.

For example, the voice output control program 64f causes the voice output unit 4 to output the guidance information in the guidance mode selected by the execution of the voice guidance mode selection program 64b acquired by the execution of the guidance information acquisition program 64d. It is a program for realizing the function.
Specifically, in the execution of the above-described guidance information acquisition program 64d, according to the set guidance mode, at each provision point, the official name of the guidance destination road / common name of the road / tourist guidance information / user input When the guide information corresponding to the keyword is acquired from the road information, the CPU 61 outputs the acquired guide information from the voice output unit 4 and provides the guide information.
The CPU 61 functions as an audio output control unit by executing the audio output program.

Here, the voice guidance process in the execution of the voice output control program 64f will be specifically described.
For example, when the guidance mode set in the voice guidance mode selection program 64b is the second guidance mode, the CPU 61 guides the vehicle when the current position of the host vehicle is a guidance information providing point in the second guidance mode. When the common name of the road (for example, “XX street”) is acquired within a predetermined distance range (for example, within 10 m) from the intersection to be performed, route guidance information using the acquired common name of the road (for example, “Next” Turn right at the intersection of XX and enter XX street. ”) Is output by the voice output unit 4 to provide route guidance.

  Further, for example, when the guidance mode set in the voice guidance mode selection program 64b is the third guidance mode, the CPU 61 determines that the current position of the host vehicle is the same as the coordinates as the guidance information providing point in the third guidance mode. Then, when the tourist information associated with the provision point is acquired, the acquired tourist information (for example, “The farm that can be seen on the right side produces local specialty products Δ △”) is voiced. The information is output by the output unit 4 to provide sightseeing guidance.

  Further, for example, when the first to fourth guidance modes are set in the voice guidance mode selection program 64b and the keyword of the fourth guidance mode input by the user is “convenience store”, the CPU 61 determines the current position of the host vehicle. Becomes a provision point of guidance information in each guidance mode, and by executing the guidance information acquisition program 64d, from the road information, the official name of the road (for example, “National highway XX line”), the common name of the road (for example, "XX street"), tourist information, and guidance information that matches the keyword "convenience store" entered by the user, each guidance information obtained (for example, "turn right at the next intersection. × Enter the street. "" Go straight about 100m. There is a convenience store on the left. " We produce specialties △△ of the band. ") And output by the audio output unit 4 at each predetermined timing, the route guidance, the tourist keyword guide.

  That is, the user selects a guidance mode for guidance information to be displayed on the display unit 3 and a guidance mode for guidance information to be output to the voice output unit 4. Can be individually selected from the keyword guidance based on the entered keywords. For example, it is possible to display tourist guidance and route guidance using the official name of the road on the display unit 3 and simultaneously output route guidance using the common name of the road from the voice output unit 4. Therefore, the provision of guidance information in the navigation device 100 can be realized by a method optimal for the user.
