And the facility at the start point of the second display section overlap, the displayed facility information (facility name 39) is three. On the other hand, when the two display sections are discontinuous, as shown in FIG. 10, there are no facilities overlapping at the boundaries of the display sections, so that the displayed facility information (facility name 39) is four.

  For example, among the additional facility icons 45 corresponding to the candidate additional facilities, the user presses a convenience store (“convenience store”), a restaurant (“meal”), a post office (“〒”), and a bank (“bank”), select. Subsequently, when the return icon B on the facility display change screen M4 is pressed, as shown in FIG. 10, the guidance screen M3 is pressed, and the current location in the section where the additional facility corresponding to the selected additional facility icon 45 is present is displayed. The display section which is two sections from the near side, the facility of the display section, and the additional facility index 45a of the display target additional facility are displayed. That is, an additional facility index 45a corresponding to a convenience store and a bank is displayed in the section (display section) from Edobashi Kita intersection to Honmachi 2-chome intersection, and in the section (display section) from Higashi Matsushitacho intersection to Iwamotocho intersection Displays an additional facility index 45a corresponding to a convenience store, a restaurant and a post office.

  That is, as shown in FIG. 8, the section from the Edobashi Minami intersection to the Edobashi north intersection, which is a facility not equipped with the selected additional facility even in the vicinity of the current location, is not displayed. Then, as shown in FIG. 10, facility information (facility name 39) of the Edobashi Kita intersection, Honmachi 2-chome intersection, Higashimatsushitacho intersection, and Iwamotocho intersection, which are the facilities in the section (display section) with the selected additional facility Only the additional facility index 45a of the additional facility between the respective facilities is displayed. Therefore, only necessary information is displayed concisely.

  In addition, the distance from the present location to the Edobashi Kita intersection is 780 meters, the distance from the present location to the Honmachi 2-chome intersection is 1.0 km, the distance from the present location to the Higashi Matsushitacho intersection is 1.8 km, and the present location to the Iwamotocho intersection The distance is displayed as 2.0 kilometers. Accordingly, since the distance from the current location to each facility can be easily grasped, the longest distance from the current location to each display target additional facility can be grasped.

Next, the operation of the navigation device 1 described above will be described.
Also in this embodiment, it is assumed that the navigation apparatus 1 has previously performed destination setting and route search (step S11 and step S15 in FIG. 6) in advance. Also in the present embodiment, for example, the search processing unit 33 searches for a plurality of guide routes, and calculates the required time to the destination of each guide route based on the traffic information of each link constituting the guide routes. The search processing unit 33 selects the guide route having the shortest required time among the guide routes as the guide route R2. In the present embodiment, the selected guide route R2 includes only a general road, and the guide route R2 is displayed on the display unit 13 as a guide image GP2 as shown in FIG. Then, route guidance is started (step S20 in FIG. 6), and facility display change processing (step S60 to step S80 in FIG. 11) is performed.

  First, the main control unit 11 determines whether or not the user has pressed the facility display change icon 43 on the guidance screen M3 displayed on the display unit 13 (step S60). If the main control unit 11 determines that the user has not pressed the facility display change icon 43 (NO in step S60), the facility control change process is terminated, and route guidance is performed without changing the facility display (FIG. 6). Step S20) is continued. On the other hand, when determining that the user has pressed the facility display change icon 43 (YES in step S60), the main control unit 11 displays the facility display change screen M4 on the display unit 13 instead of the guidance screen M3 (step S65). ). Then, the main control unit 11 (change processing unit 35) searches the additional facility information, and can press the additional facility icon 45 indicating the additional facility ahead of the current location in the traveling direction on the facility display change screen M4 (selection). Is displayed (step S70).

  Next, the main control unit 11 determines whether or not to change the facility display (step S75). That is, it is determined whether or not the user has pressed and selected the additional facility icon 45 on the facility display change screen M4. If it is determined that the user has not pressed (selected) any additional facility icon 45 and the return icon B has been pressed (NO in step S75), the main control unit 11 ends the facility display change process, and the route The guidance (step S20) is continued. On the other hand, if it is determined that the user has pressed and selected the additional facility icon 45 and then pressed the return icon B (YES in step S75), the main control unit 11 indicates that the user intends to change the facility display. I reckon. Then, an additional facility indicator 45a of the selected additional facility, a facility name 39 of the facility in the display section, and a guidance screen M3 displaying a distance 41 that is the distance from the current location to the facility are displayed on the display unit 13 (step S13). S80).

  Then, the main control unit 11 repeats the facility display change process (steps S60 to S80) according to the user's instruction until the destination is reached, and ends the route guidance (step S20) when the destination is reached. To do.

According to the second embodiment, the following effects can be obtained.
(1) According to this embodiment, while traveling on a road such as a general road that has an additional facility in a section between the facilities, the facility among the additional facilities in the section ahead of the current position in the traveling direction The additional facility selected by the user on the display change screen M4 is searched. Then, two sections from the section closer to the current location among the sections with the searched additional facilities are set as display sections, and the additional facilities in the display section are set as display target additional facilities. Only the facility name 39 of the display section, the distance 41 from the current location to the facility, and the additional facility index 45a corresponding to the display target additional facility are displayed on the guidance screen M3. Therefore, only information necessary for the user (additional facility) can be displayed in a simple but easy-to-understand manner.

  (2) According to this embodiment, a plurality of additional facilities to be displayed on the guidance screen M3 can be selected. Therefore, it is possible to display a simple and easy-to-understand display while selecting a plurality of additional facility information necessary for the user.

(3) According to this embodiment, since the distance 41 from the current location to the facility in the display section is displayed on the facility information display image D2, the longest distance to the desired additional facility can be easily grasped. . Therefore, for example, with reference to the distance 41, it is possible to determine which of the facilities provided with the desired additional facility to be used.

In addition, you may change each said embodiment as follows.
In the first embodiment, the search processing unit 33 searches for the guide route R1 using the expressway, and the user selects an additional facility provided in a facility along the expressway included in the guide route R1. When the user travels on the highway without searching for the guidance route R1, the user may select an additional facility provided in a facility along the highway. At this time, since the destination is not set, the search range of the facility and the additional facility is from the current location to the end of the traveling highway. As a result, the same effect as the first embodiment can be obtained.

  In the first embodiment, the indicator (type name) indicating the additional facility is not displayed on the guidance screen M1 after the facility display change process, but the indicator (type name) indicating the additional facility is displayed together with the facility name 39. It may be displayed. Thereby, it is possible to easily determine which additional facility the facility (facility name 39) on the guidance screen M1 includes.

  In the first embodiment, the number of facility names 39 displayed on the guidance screen M1 is three from the side closer to the current location. Three or more facility names 39 may be displayed. Alternatively, scroll buttons may be provided on the guide screens M1 and M3, and the guide screens M1 and M3 may be scrolled by pressing the scroll buttons. That is, for example, when the guide screens M1 and M3 are scrolled in the traveling direction, a facility provided with an additional facility selected by the user further ahead in the traveling direction than the facility displayed on the guidance screens M1 and M3, Alternatively, the facilities selected by the user can be displayed in order. Thereby, the facility provided with the additional facility selected by the user other than three from the one close to the current location, or the facility selected by the user can be confirmed.

  In the first embodiment, one type of additional facility that can be selected from the candidate additional facilities is used. However, two or more types of additional facilities may be used. At this time, an indicator (type name) corresponding to the additional facility selected by the user is displayed on the guidance screen M1, thereby indicating which type of additional facility among the additional facilities selected by the user is located in which facility. It can be grasped intuitively.

  In the first embodiment, when there is a facility stored in advance in the facility information storage unit 23 that does not exist ahead of the current position in the traveling direction, the facility icon 44 corresponding to the facility that does not exist is displayed on the facility display change screen M2. In the above, it was impossible to press (selectable). If there is a facility stored in advance in the additional facility information storage unit 25 that does not exist ahead of the current position, the facility icon 44 corresponding to the facility that does not exist is not displayed on the facility display change screen M2. You may do it.

  In the first embodiment, the facility display change screen M2 is displayed by switching the guidance screen M1, and a desired facility and additional facility are selected on the facility display change screen M2. Alternatively, the facility display change screen M2 may be displayed on a part of the guidance screen M1 without switching the screen.

  In the second embodiment, the search processing unit 33 searches for the guide route R2 using the general road, and the user selects an additional facility in the section on the guide route R2, but does not search for the guide route R2. When traveling on a general road, the user may select an additional facility adjacent to the general road. At this time, the search range of the additional facility is from the current location to the end of the traveling general road. As a result, the same effect as in the second embodiment can be obtained.

  In the second embodiment, only the facility name 39 is displayed as facility information on the guidance screen M3. This may be displayed together with the facility name along with the facility name. Thereby, the kind of facility in which the facility name is displayed can be easily grasped.

  In the second embodiment, a section between a facility and a facility on a general road is a section, and an additional facility adjacent to the section is a candidate additional facility. For example, about 100 m perpendicular to a general road (corresponding to the vicinity of the road described in claim 10) may be set as a section, and an additional facility in the section may be set as a candidate additional facility. This makes it possible to display additional facilities that are actually available. That is, for example, on a general road that can be changed relatively freely, unlike a road that can only change a road that travels only at a facility (interchange etc.) that is determined to start once such as an expressway, Not only the additional facilities adjacent to the currently traveling road but also the additional facilities near the currently traveling road can be used. Therefore, the additional facility information required by the user can be selected by setting the additional facility near the general road as a candidate additional facility.

  In the second embodiment, the facility display change screen M4 is displayed by switching the guidance screen M3, and a desired additional facility is selected on the facility display change screen M4. Alternatively, the facility display change screen M4 may be displayed on a part of the guidance screen M3 without switching the screen.

  In each of the above embodiments, when there is a facility that is stored in advance in the additional facility information storage unit 25 and that does not exist ahead of the current position in the traveling direction, the additional facility icon 45 corresponding to the additional facility that does not exist is changed to the facility display. It was made impossible to press (cannot be selected) on screens M2 and M4. If there is a facility that is stored in advance in the additional facility information storage unit 25 and does not exist ahead of the current position, the additional facility icon 45 corresponding to the additional facility that does not exist is displayed on the facility display change screens M2 and M4. It may not be displayed above.

In each of the above embodiments, a suitable result has been obtained by applying to the navigation device 1, but this may be applied to the navigation device 1 and a navigation system provided with the navigation device 1.
In this case, as shown in FIG. 12, the navigation device 1 is a navigation device attached to an automobile CA, and the navigation device 1 can communicate with the information center NC via a network M such as a mobile phone network. It is a state. Thus, the navigation system A is comprised by the navigation apparatus 1 and the information center NC. The navigation device 1 in the navigation system A is registered in advance in the information center NC, and each navigation device 1 is managed by a user ID.

  The navigation apparatus 1 does not include the facility information storage unit 23 and the additional facility information storage unit 25, and the information center NC includes the facility information storage unit 23 and the additional facility information storage unit 25 corresponding to the user ID of each user. Provide. When the navigation apparatus 1 transmits the user ID and the guidance route to the information center NC via the network M during the facility display change process, the information center NC navigates the candidate facility and candidate addition facility on the guidance route. Transmit to device 1.

By doing in this way, since it is not necessary to provide the facility information storage part 23 and the additional facility information storage part 25 in the navigation apparatus 1, the navigation apparatus 1 can be reduced in size.
Further, the navigation device 1 is not provided with the change processing unit 35, but the information center NC is provided with the change processing unit 35 and the facility information storage unit 23 and the additional facility information storage unit 25 corresponding to the user IDs of the respective users. When the navigation apparatus 1 performs the facility display change process, if the user ID and the guidance route are transmitted to the information center NC via the network M, the information center NC selects the candidate facility and the candidate additional facility on the guidance route. It transmits to the navigation device 1. When the user selects a display target facility or a display target additional facility from the candidate facilities and the candidate additional facilities, the information center NC transmits the display target facility or the display target additional facility to the navigation device 1.

By doing in this way, since the navigation apparatus 1 does not need to search the facility information storage part 23 and the additional facility information storage part 25 among the facility display change processes, the number of processes executed by the navigation apparatus 1 may be reduced. it can. Therefore, it is possible to display the additional facility selected by the user more easily and easily while being a simple and small device.

  In the above embodiments, the distance 41 from the current location to each facility is displayed in the facility information display image D1. Alternatively, an estimated travel time that is a time required to travel from the current location to each facility, or an estimated arrival time that is an estimated time to arrive at each facility may be displayed. Thereby, it is possible to easily grasp the time required to travel from the current location to each facility. The expected travel time and expected arrival time can be calculated by a known method using traffic information received from the road traffic information communication system, traffic information received from the information center, or the like. Further, the traffic information (expected travel time) itself received from the road traffic information communication system or the traffic information (expected travel time) itself received from the information center may be displayed.

  In each of the above embodiments, the route search is performed by the navigation device 1 first searching for a plurality of guide routes, and based on the traffic information of each link constituting the guide routes, the required route to the destination of each guide route. Calculate time. And the navigation apparatus 1 selects the guidance route with the shortest required time among the respective guidance routes. Alternatively, the navigation device 1 may search for only one optimum guide route during route search. That is, using the link traffic information and connection information between links such as traffic restrictions, etc., the guide route cost (evaluation value for the guide route) from the departure point (current location) to each node is calculated, and the route to the destination is calculated. When all cost calculations are completed, a link that minimizes the guide route cost may be connected to search for only one optimum guide route.
