  FIG. 3 shows a flowchart of the peripheral facility search process in S200. In this peripheral facility search process, first, an operation mode is determined (S202). Specifically, it is determined with reference to the operation mode flag area of the memory whether the operation mode is set to “outing mode”, “moving mode”, or “location condition confirmation mode”.

  If the “moving mode” is set, then the center of the search area is set to the new location (S204). Specifically, the home position after being changed by the home position registration process is specified as the central point of the search target area.

  If the “outing mode” is set, then the center of the search target area is set to the current location (S206). Specifically, the current location calculated by the vehicle position calculation process is specified as the central point of the search target area.

  If it is set to the “location condition confirmation mode”, an arbitrary place setting screen is displayed on the display unit 16 (S208). This arbitrary place setting screen is configured by a scroll map screen or an address input screen, and these screens are switched in accordance with a user operation.

  Next, the center of the search target area is set to an arbitrary place (S210). Specifically, an arbitrary place specified on the scroll map screen by the user's operation or an arbitrary place corresponding to the address input on the address input screen by the user's operation is set as the central point of the search target area.

  In S212, a target facility search is performed according to the operation mode (S212). Specifically, a search list is prepared for each operation mode, and a storage medium in which map data is stored for facility information existing in the search target area in accordance with the search list prepared as the operation mode determined in the previous S202 Search in bulk. Here, the search target area is a predetermined section based on the central point of the search target area.

(1) Operation mode: moving mode and location condition confirmation mode As shown in FIG. 4, a municipal office (for example, a city hall), a school, a station, a hospital, a pharmacy, a bank, a post office, a supermarket (in the figure, a supermarket) A search list in which facility classifications such as home centers and dealers are defined is prepared. For each facility classification, the facility search method shown in the figure, for example, municipal office, school, station, A batch search is performed by sequentially searching for facilities existing in the search target area such as a hospital or the like.

  When searching for a municipal office, the local government office in the corresponding area is identified from the address of the central point of the search target area, and the municipal office in the corresponding area is searched.

  When searching for a school, the school district of the central point of the search target area is identified from the address of the central point of the search target area, and the school (for example, elementary school, junior high school) of this school district is searched. Therefore, in this embodiment, schools in other school districts are not searched. For schools that are not related to school districts, such as universities, schools that are in the search area are searched regardless of school districts.

  When searching for a station, the search is performed in order from the shortest distance from the central point of the search target area by route (for example, JR, private railway, public service, etc.).

  When searching for a hospital, search is performed in order from the shortest distance from the central point of the search target area for each medical subject (internal medicine, surgery, ophthalmology, etc.).

  When searching for a pharmacy, the search is performed in order of increasing distance from the central point of the search target area.

  In the case of “outing mode”, as shown in C in the figure, a message such as “Do you want to display information on nearby facilities that are useful for unexpected situations when going out?” Is displayed on the display unit 16. In addition, display switches such as “display icon on map”, “display facility list”, and “do not display” are displayed in a selectable manner.

  Next, the display mode is determined (S218). Specifically, the display mode is determined based on which display switch is selected and operated according to the display mode selection screen shown in FIG.

  Here, according to the display mode selection screen, when a display switch indicating “map icon display” is selected and operated, an icon is displayed on the map (S220). Specifically, an icon representing each facility searched in the previous S212 is displayed in a selectable manner on a map including the central point of the search target area. The center point of the search target area is a new location in the “moving mode” or an arbitrary place designated by the “location condition confirmation mode”.

  FIG. 7 shows a screen display example when the display switch indicating the icon display on the map is selected and operated. On this screen, the post office P and the school S1 searched on the map including the new home position are displayed as icons. In addition, although the school S2 in a figure exists near the new residence position rather than the school S1, since it is a school of another school district, it is not actually displayed.

  Next, it is determined whether the target facility on the map has been selected (S222). Specifically, it is determined whether a specific icon has been selected from the icons of the facilities displayed on the screen or a display switch (not shown) for instructing the end of the search process has been selected.

  Here, when a specific icon is selected according to the icon display screen on the map, the determination in S222 is YES, and then the facility representing the selected icon is set as the destination of the route search (S224). This process is terminated.

  When the destination of the route search is set in this way, the control circuit 19 searches for an optimum guide route from the current location to the destination, and a route guide processing (in which the route guidance is performed according to the searched guide route) Neither is shown).

  If a display switch for instructing the end of the search process is selected according to the icon display screen on the map, the determination in S222 is NO and the process ends.

  If the display switch indicating “target facility list display” is selected and operated in accordance with the display mode selection screen, the target facility list screen is displayed (S226). Specifically, each facility searched in the previous S212 is displayed as a selectable list. In addition, when a plurality of facilities are searched for the same facility classification, the facility information is displayed in ascending order of required time.

  FIG. 8 shows a display example of a list display screen of “moving mode” and “location condition confirmation mode”. In the “moving mode” and “location condition confirmation mode”, a peripheral facility search is performed for each facility classification shown in FIG. 4, and the search result is displayed as a list display screen as shown in FIG. The list display screen displays the facility name and the required time from the central point of the search target area for each display facility classification. The center point of the search target area is a new location in the “moving mode” or an arbitrary place designated by the “location condition confirmation mode”.

  FIG. 9 shows a display example of the “outing mode” list display screen. In the “outing mode”, a peripheral facility search is performed for each facility classification shown in FIG. 5, and the search result is displayed as a list display screen as shown in FIG. The list display screen displays the facility name and the required time from the vehicle position for each display facility classification.

  In the “outing mode” for the purpose of searching the surrounding facilities of the vehicle location, the location of the municipal office corresponding to the area around the vehicle location and the location of the school in the district around the vehicle location is not so important, In the “Moving Mode” for the purpose of searching the surrounding facilities of the destination, and the “Condition Condition Check Mode” for searching for the surrounding facilities of the candidate destination, the location and destination of the municipal office in the destination area The school location of the school district is very important information. Therefore, as shown in FIGS. 8 and 9, in the “moving mode” and “location condition confirmation mode”, a municipal office (for example, a city hall) in the corresponding area and a school in the corresponding school district are searched. In “outing mode”, municipal offices and schools are not searched. In this way, different search lists are prepared depending on the operation mode, and the contents of search and display are different.

  Next, according to the list display screen, it is determined whether a specific facility has been selected or a display switch for instructing the end of the search process has been selected (S228).

  When a specific facility is selected according to the list display screen, the determination in S228 is YES, and the process proceeds to S224. As a result, the selected facility is set at the destination.

  Then, route search processing for searching for an optimum guide route from the current location to the destination, and route guide processing (not shown) for performing travel guidance according to the searched guide route are performed.

  If the display switch for instructing the end of the search process is selected, the determination in S228 is NO and the process ends.

  If the display switch indicating “not display” is selected and operated according to the display mode selection screen shown in FIG. 6, the present process is terminated without displaying the search result.

  According to the above configuration, the facility information existing in the search target area is collectively searched from the storage unit according to the search list in which the facility classification to be searched is defined, and the searched facility information is displayed on the display unit. It is possible to search for peripheral facilities corresponding to a plurality of facility classifications without designating the facility classification.

  In addition, since facility information is searched according to the search list prepared as the set operation mode, for example, in the operation mode for searching surrounding facilities at the own vehicle position, it is prepared for searching surrounding facilities at the own vehicle position.
