  The system controller 20 includes an interface 21, a CPU 22, a ROM 23, and a RAM 24, and controls the entire navigation device 1. For example, the system controller 20 executes a route search to the destination designated by the user and route guidance for the searched route. Further, in this embodiment, the system controller 20 automatically searches for facilities that are candidates for a stop (also referred to as “stop candidate facilities”) when the destination is set, and obtains a search result regarding the stop candidate facilities. The display unit 40 and the audio output unit 50 notify the user. The drop-in candidate facility is a facility having a predetermined relationship with the destination, for example, a peripheral facility around the destination having equipment not at the destination. The system controller 20 is an example of a “search unit”, “history recording unit”, “acquisition unit”, “input reception unit”, “notification unit”, and a computer that executes a program according to the present invention. A drop-in candidate facility is an example of a “point to be a drop-in candidate” in the present invention.

  The interface 21 performs an interface operation with the autonomous positioning device 10 and the GPS receiver 18. The interface 21 inputs these output data to the system controller 20. The CPU 22 controls the entire system controller 20. The ROM 23 includes a nonvolatile memory (not shown) in which a control program for controlling the system controller 20 is stored. The RAM 24 stores various data such as route data preset by the user via the input device 60 so as to be readable, and provides a working area to the CPU 22.

  The system controller 20, the data storage unit 31, the display unit 40, the audio output unit 50, and the input device 60 are connected to each other via the bus line 30.

  The data storage unit 31 is configured by, for example, a storage medium such as an HDD or a flash memory, and stores various data used for navigation processing such as map data. The map data includes road data represented by links corresponding to roads and nodes corresponding to road connecting portions (intersections), and facility information regarding each facility that can be set as a destination. Further, in this embodiment, the data storage unit 31 stores a determination table 32 that is referred to by the system controller 20 when determining a stop-by candidate facility to be notified to the user from the set destination. A specific example of the data structure of the determination table 32 will be described later with reference to FIG. The determination table 32 is an example of “correspondence information” in the present invention.

  The communication device 38 receives traffic information distributed from a VICS (registered trademark, Vehicle Information Communication System) center, traffic information distributed from a server device that distributes traffic information (not shown), and the like. The communication device 38 may receive information to be stored in the data storage unit 31 as map data from a server device (not shown) based on the control of the system controller 20.

  The display unit 40 displays various display data on a display device such as a display under the control of the system controller 20. Specifically, the system controller 20 reads map data from the data storage unit 31.

For example, instead of or in addition to the display 44, the navigation device 1 may include a head-up display that allows the driver to visually recognize a virtual image via a vehicle window shield or a combiner.

(2) Example of data structure of determination table Next, a specific example of the data structure of the determination table 32 will be described.

  FIG. 2A is a first specific example showing the data structure of the determination table 32. In the example of FIG. 2A, the determination table 32 includes items of “destination category” and “stop candidate category”. Here, “destination category” indicates each category when facilities that can be set as destinations are classified, and “stop candidate category” indicates a stop when a destination belonging to the corresponding destination category is set. Indicates the category of facility that should be set as a candidate facility.

  Here, a specific example referring to the determination table 32 shown in FIG. For example, when the facility belonging to the “campground” category is set as the destination, the system controller 20 refers to the first record in the determination table 32 shown in FIG. 2A and the category is “supermarket”. It is determined that the facility to be set as a candidate facility for drop-off. Therefore, in this case, the system controller 20 refers to the facility information of the map data stored in the data storage unit 31 and, for example, a supermarket that is within a predetermined distance from the destination or within a predetermined distance from the set route to the destination. Search for. Then, the system controller 20 regards the found facility as a drop-in candidate facility, and performs notification that recommends a drop-in to the facility. Thereby, before reaching the campsite, the system controller 20 can prompt a stop at a supermarket suitable for purchasing items necessary for barbecue and the like at the campsite.

  Similarly, when the facility belonging to the inn category is set as the destination, the system controller 20 refers to the second record in the determination table 32 and sets the facility whose category is a convenience store as a drop-in candidate facility. Judge that it should. Therefore, the system controller 20 searches for convenience stores around the destination or the route, and makes a notification that recommends stopping at the searched convenience store. Thereby, before reaching the inn, the system controller 20 can prompt a stop at a convenience store suitable for purchasing goods required in the inn.

  In this way, in the example of FIG. 2A, for each destination category, a stop-by candidate category, which is a category of a facility that is preferable to stop when going to a facility belonging to the corresponding destination category, is associated. Note that the determination table 32 shown in FIG. 2A is created in advance by, for example, a personal method and stored in the data storage unit 31. In addition, preferably, in FIG. 2A, information for specifying the content to be notified may be associated with each combination of “destination category” and “stop candidate category”. A specific example of the notification content will be described later with reference to FIG.

  FIG. 2B is a second specific example showing the data structure of the determination table 32. In the example of FIG. 2B, the determination table 32 includes items of “Destination” and “Trip candidate facility”. Here, facilities that can be set as destinations are registered in the “destination”, and if the facilities indicated by the “destination” are set as destinations, the “stop destination candidate facilities” Facilities that should be set as are registered.

  Here, a specific example in which the determination table 32 shown in FIG. 2B is referred to will be described. For example, the system controller 20 aims at “A Land” which is a large amusement facility in which parking lot traffic frequently occurs. When it is set as the ground, the first record in the determination table 32 is referred to, and “Michi-no-eki B”, which is a facility where toilet rest is possible, is considered as a stop-by facility, and “Michi-no-eki B” is stopped by Informs that it should be the ground. As a result, the system controller 20 can preferably prompt a toilet break at “Road Station B” in consideration of the occurrence of a parking lot congestion at “A Land”. Similarly, the system controller 20 refers to the third record in the determination table 32 when “E plantation”, which is a facility that does not have a parking lot, is set as the destination, and determines the shuttle bus to the E plantation. The “F factory”, which is the departure point and has a parking lot, is regarded as a drop-in candidate facility, and notification is made that “F factory” should be a stop-by place. In this way, the system controller 20 takes into account that “E Farm” is a facility that does not have a parking lot, and preferably encourages a stop-off to the “F Factory” where the parking lot is located. be able to.

  In this way, in the example of FIG. 2B, for each specific facility that can be set as a destination, a drop-in candidate facility that is a facility recommended to stop when going to the facility is associated. Note that the determination table 32 shown in FIG. 2B is created in advance by, for example, a personal method and stored in the data storage unit 31. In addition, preferably, in FIG. 2B, information for specifying the content to be notified may be associated with each combination of “destination” and “stop candidate facility”.

  The data storage unit 31 may store both the determination table 32 having the data structure shown in FIG. 2A and the determination table 32 having the data structure shown in FIG. In this case, for example, the system controller 20 preferentially refers to the determination table 32 in FIG. Then, when the set destination is not registered in the determination table 32 shown in FIG. 2B, the system controller 20 shown in FIG. 2A based on the set destination category. The determination table 32 is referred to. In this case, the system controller 20 refers to the determination table 32 shown in FIG. 2A to recognize the category of the facility that should be set as the stop-by candidate facility, and the vicinity of the destination or the route around the destination. Applicable facilities are considered as drop-in candidate facilities.

(3) Processing Flow FIG. 3 is a flowchart showing an outline of guidance processing for a drop-in candidate facility. The system controller 20 executes the process of the flowchart shown in FIG. 3 every time it detects that the destination has been set.

  First, when there is an input for designating a destination, the system controller 20 searches for a route to the destination designated by the user (step S101). Then, the system controller 20 refers to the determination table 32 and searches for a drop-in candidate facility based on the destination (step S102). Here, when referring to the determination table 32 in FIG. 2A, the system controller 20 recognizes the category of the destination based on the facility information included in the map data in the data storage unit 31, and determines from the category. The category of the drop-in candidate facility is specified with reference to the determination table 32 in FIG. Then, the system controller 20 searches for facilities belonging to the identified category with a destination or route periphery as a search range. When the system controller 20 refers to the determination table 32 in FIG. 2B, the facility associated with the set destination in the determination table 32 is used as map data in the data storage unit 31. Search from included facility information.

  Then, the system controller 20 determines whether or not the corresponding drop-in candidate facility has been identified by the search in step S102 (step S103). Then, when the corresponding drop-off candidate facility can be identified by the search in step S102 (step S103; Yes), the system controller 20 guides the drop-off candidate facility (step S104). In this case, for example, the system controller 20 performs display or / and audio output for notifying the existence of the searched stop-by candidate facility, and accepts an input for setting the searched stop-by candidate facility as a stop-by place. Note that the system controller 20 only performs display or / and audio output for notifying the presence of the searched stop candidate facility, and does not need to accept an input for setting the searched stop candidate facility as a stop point.

  On the other hand, the system controller 20 complete | finishes the process of a flowchart, when the corresponding drop-in candidate facility cannot be specified by the search of step S102 (step S103; No).

(4) Display Example FIG. 4 shows a display example that is displayed on the display 44 when guiding a drop-in candidate facility in step S104 of FIG.

  In the example of FIG. 4, after the route to the destination is set, the system controller 20 refers to the determination table 32 of FIG. B "is determined. The system controller 20 displays the current position, the location of the destination “A Land”, the route to the destination, and the location of the candidate stop facility “Road Station B” on the map, and the candidate stop facility “Road” A pop-up window 70 that prompts the user to set the station No. B as a stop-by place is displayed.

  Here, in the pop-up window 70, the system controller 20 recommends that the destination “A Land” is expected to have a parking lot congestion, and that the rest is resting at the drop-off candidate facility “Michi no E Station B”. Is displayed. In this case, the system controller 20 determines the display content on the pop-up window 70 by referring to information indicating the content to be notified that is registered in each record of the determination table 32, for example. Further, the system controller 20 displays a button for inputting whether or not the drop-down candidate facility “Michi-no-eki B” is set as a stop-off place in the pop-up window 70. When the “YES” button in the pop-up window 70 is selected, the system controller 20 performs a route search using “Michi-no-Eki B” as a stopover and starts guidance for the route. On the other hand, when the “NO” button of the pop-up window 70 is selected, the system controller 20 deletes the display of the pop-up window 70 and performs route guidance to the destination.

  As described above, in the display example of FIG. 4, the system controller 20 is a drop-off facility that is a facility with a toilet associated with the determination table 32 based on destination information (that is, information indicating that parking lot traffic is likely to occur). Guide candidate facilities. Thereby, the system controller 20 can suitably guide a facility that is preferable for the user as a stop-by candidate facility.

<Second embodiment>
In the second embodiment, the navigation device 1 records attributes relating to the presence or absence of specific equipment for each facility that can be set as a destination, instead of the determination table 32 illustrated in FIGS. 2 (A) and 2 (B). It has a determination table 32A. Then, the navigation device 1 determines the facility to be searched as a drop-in candidate facility in consideration of the destination attribute recognized with reference to the determination table 32A.

  FIG. 5 is an example of the data structure of the determination table 32A stored in the data storage unit 31 in the second embodiment. The determination table 32A includes “Destination”, “Division”, “Handling of daily necessities / food”, “Nearby facilities handling daily necessities / food”, “Toilet”, “Nearby facilities with toilet”, “Restaurant”, Each item includes “parking lot”, “allowable eating and drinking space”, and “parking lot traffic”.

  In “Destination”, a facility that can be set as a destination is recorded, and in “Division”, the category of the facility recorded in “Destination” is recorded. In addition, “Handling of daily necessities / food” records the presence / absence of handling of daily necessities / food in facilities recorded in “Destination”, and “Destination” in “Peripheral facilities handling daily necessities / food”. The presence or absence of facilities handling daily necessities and foods around the recorded facilities is recorded. In addition, “Toilet” records the presence / absence of toilets at facilities recorded in “Destination”, and “Nearby facilities with toilets” includes facilities with toilets around facilities recorded in “Destinations” The presence or absence of is recorded. In addition, “restaurants”, “parking lots”, and “branchable eating spaces” each include the presence or absence of restaurants attached to facilities recorded in “Destination”, the presence or absence of parking lots, and carry-in The presence or absence of a possible eating and drinking space is recorded. Also, “parking lot traffic” records whether or not the traffic jam is statistically likely to occur in the parking lot attached to the facility recorded in “destination”.

  In this way, the determination table 32A includes, in addition to attribute information regarding the presence / absence of each facility (that is, daily necessities handling facilities, toilet facilities, restaurants, parking lots, etc.) in the facility recorded in “Destination”, Attribute information such as the presence / absence of an alternative facility having each facility around the target facility and the presence / absence of parking lot congestion is recorded.

  Here, in the determination table 32A shown in FIG. 5, each item other than “Destination” and “Segment” is divided into three categories according to the characteristics of each item described above. Specifically, “Handling of daily necessities / food”, “Toilet”, “Restaurant”, “Parking”, and “Eating and drinking space” are classified as “Characteristic 1” and “Parking congestion” Are classified as “characteristic facilities 2”, and “peripheral facilities handling daily necessities / food” and “peripheral facilities with toilets” are classified as “presence / absence of alternative facilities”.

  The information corresponding to the determination table 32A may be incorporated in advance as part of the facility information for each facility included in the map data stored in the data storage unit 31. The determination table 32A according to the second embodiment is an example of “attribute information” in the present invention.

  Next, the process which the navigation apparatus 1 performs in 2nd Example is demonstrated. In the second embodiment, the system controller 20 executes the flowchart of FIG. 3 as in the first embodiment. At this time, when searching for a drop-in candidate facility in step S102, the system controller 20 refers to the determination table 32A to search for a drop-off candidate facility.

  In the first example, the system controller 20 refers to the determination table 32 </ b> A and refers to the “presence / absence of alternative facility” corresponding to the feature facility 1 when the facility set as the destination does not have the predetermined feature facility 1. When the item “” is “◯”, the peripheral facility having the characteristic facility 1 is searched as a drop-in candidate facility. In addition, the system controller 20 has a case where the destination facility does not have the predetermined feature equipment 1 and the item “existence of alternative facility” corresponding to the feature equipment 1 does not exist in the determination table 32A. A peripheral facility having the characteristic facility 1 is searched as a drop-in candidate facility.

  Here, the case where the facility set as the destination does not have the predetermined characteristic equipment 1 and the item “existence of alternative facilities” corresponding to the characteristic equipment 1 is “◯” will be exemplified. For example, in the determination table 32A, a facility in which “handling of daily necessities / food” is “x” and “peripheral facilities handling daily necessities / food” is “○” (for example, “J campsite”) is set as the destination. In such a case, an object to be searched as a drop-in candidate facility is set to a peripheral facility (for example, a supermarket) that handles daily necessities and food. Similarly, the system controller 20 sets a facility (for example, “K waterfall”) in which “toilet” is “×” and “peripheral facility with toilet” is “◯” in the determination table 32A (for example, “K waterfall”). In the case of the case, the object to be searched for as a drop-in candidate facility is set to a peripheral facility belonging to the category of the facility with toilet.

  Next, the case where the destination facility does not have the characteristic equipment 1 and the item “presence / absence of alternative facility” corresponding to the characteristic equipment 1 does not exist in the determination table 32A will be exemplified. For example, in the determination table 32A, when a facility where “parking lot” is “x” (for example, “J campsite”) is set as a destination, the system controller 20 selects a target to be searched as a drop-off candidate facility. A nearby parking lot or a surrounding facility having a parking lot is selected as a candidate for a stop-by facility.

  In the second example, the system controller 20 sets a facility (for example, “K no Taki”) in which “Restaurant” and “Eatable food space” are both “x” in the determination table 32A as the destination. If it is, the object to be searched for as a drop-in candidate facility is set as a peripheral facility belonging to the category of restaurant.

  At this time, preferably, the system controller 20 is an object to be searched as a drop-in candidate facility only when the estimated arrival time at the destination falls within a predetermined time zone (for example, a general lunch or dinner time zone). May be set as a peripheral facility belonging to the category of restaurant. Then, when the estimated arrival time at the destination is outside the predetermined time zone, the system controller 20 determines a target to be searched as a drop-in candidate facility, for example, according to the first example or a third example described later. As described above, the system controller 20 may determine an object to be searched as a drop-in candidate facility in consideration of the estimated arrival time at the destination.

  Similarly, the system controller 20 is intended for a facility (for example, “J campsite”) where “Restaurant” and “Handling of daily necessities / food” are “X” and “Eatable food space” is “○”. If the estimated arrival time at the destination is within a predetermined time zone, the object to be searched as a drop-in candidate facility is set to a peripheral facility that handles food (for example, a supermarket). .

  In the third example, the system controller 20 sets a facility with a toilet when a facility (for example, “shopping center N”) where “parking lot traffic” is “◯” in the determination table 32A is set as the destination. Peripheral facilities that belong to the category are determined as objects to be searched as drop-in candidate facilities.

  The system controller 20 may determine the drop-in candidate facility based on any of the first to third examples, or may determine the drop-off candidate facility based on all of the first to third examples. At this time, if the system controller 20 searches for a plurality of drop-down candidate facilities in step S102, the system controller 20 may guide all of the searched drop-down candidate facilities, and selects one drop-down candidate facility selected based on a predetermined rule. You may guide. Further, in the determination table 32A shown in FIG. 5, a record is generated for each individual facility that can be set as the destination. Instead of or in addition to this, the determination shown in FIG. Similarly to the table 32, a record may be generated for each category of facility that can be set as the destination.

  FIG. 6 shows a display example to be displayed on the display 44 when guiding a drop-in candidate facility in the second embodiment.

  In the example of FIG. 6, the system controller 20 sets “K Mart” as a destination, so that the facility with toilet “P Mart” is selected as a drop-in candidate facility based on the fourth record in the determination table 32A. The display recommended as a stopover is provided. Specifically, since the system controller 20 corresponds to the facility in which “toilet” is “×” and “peripheral facility with toilet” is “◯” in “K waterfall”, Based on the example, peripheral facilities belonging to the category of facilities with toilets are searched, and the facility with toilet “P Mart” is determined as a candidate facility for drop-in. Then, the system controller 20 displays the current position, the position of “K no Taki” as the destination, the position of “P Mart” as the stop-by candidate facility, and the set route on the map, and a pop-up window. 71 is displayed superimposed on the map. Further, the system controller 20 displays in the pop-up window 71 that there is no toilet at the destination “K-no-taki”, and a button for designating whether or not to set “P-mart” as a stop-off place. It is displayed. Then, when the “YES” button in the pop-up window 71 is selected, the system controller 20 performs a route search using “P Mart” as a stopover point, and starts guidance for the route. On the other hand, when the “NO” button of the pop-up window 71 is selected, the system controller 20 deletes the display of the pop-up window 71 and performs route guidance to the destination.

  As described above, the system controller 20 of the navigation device 1 according to the first and second embodiments refers to the determination table 32 or the determination table 32A when the destination is set, so that the destination And search for candidate facilities that have a predetermined relevance. And the navigation apparatus 1 performs alerting | reporting regarding the search result of a drop-in candidate facility by the display unit 40 or the audio | voice output unit 50. FIG. Thereby, the navigation apparatus 1 can alert | report suitably the drop-in candidate facility which has an association with the destination.

<Modification>
Hereinafter, modified examples suitable for the first and second embodiments will be described. These modifications may be applied in combination to the above-described embodiments.

(Modification 1)
A part of processing executed by the navigation device 1 in the first and second embodiments may be executed by a server device that communicates with the navigation device 1 via a network.

  FIG. 7 shows a configuration of a route guidance system according to a modification. In the example of FIG. 7, the route guidance system includes a navigation device 1 and a server device 3 that stores a determination table 32. Then, the server device 3 has map data, and when there is a route search request including information such as the current position and the destination from the navigation device 1, the server device 3 searches for a route to the destination and displays information on the search result. Supplied to the navigation device 1.

  In the configuration example of FIG. 7, for example, the navigation device 1 transmits a route search request including information on the current position and the destination to the server device 3. Then, the server device 3 executes the flowchart of FIG. 3 based on the received route search request. At this time, if it is determined in step S103 that the corresponding drop-off candidate facility exists, the server device 3 transmits information for guiding the drop-off candidate facility (for example, facility information regarding the drop-off candidate facility) to the navigation device 1.

  The server device 3 may store a determination table 32 </ b> A instead of the determination table 32. In this case, the server device 3 executes a search process for a drop-in candidate facility based on the determination table 32A described in the second embodiment. In the present modification, the CPU of the server device 3 is an example of the “reception unit”, “search unit”, and “transmission unit” in the present invention.

  In the configuration example of FIG. 7, the server device 3 receives and receives information (also referred to as “probe information”) related to the state of the vehicle from a plurality of in-vehicle devices such as the navigation device 1 traveling on the road. The determination table 32 may be automatically generated by analyzing the probe information. For example, based on the probe information, the server device 3 arrives at a destination set by a certain vehicle first (also referred to as “initial destination”), sets another facility as the destination, and heads to the facility. If it is determined that the vehicle has arrived at the initial destination again, it is determined that it is preferable to stop at the other facility described above in order to stay at the initial destination. Therefore, in this case, the server apparatus 3 adds a new record in the determination table 32 of FIG. 2B, in which the initial destination is the “destination” and the other facility described above is the “stop candidate facility”. . In this case, the probe information received from the navigation device 1 may include destination setting history information and the like. By doing so, the server device 3 can suitably automatically generate the determination table 32.

(Modification 2)
In the flowchart of FIG. 3, the navigation apparatus 1 searches and guides the candidate facility for drop-off at the same time as the route search to the destination. Instead, after the route search to the destination is completed and the route guidance to the destination is started, the navigation device 1 performs processing related to the search and guidance for the drop-in candidate facility before arriving at the destination at the latest. May be executed.

(Modification 3)
In the flowchart of FIG. 3, the navigation device 1 may determine whether or not to guide the drop-down candidate facility in step S <b> 104 based on the movement history of the vehicle.

  In this case, the system controller 20 determines whether or not the user has actually stopped at the drop-off candidate facility when, for example, guidance is provided for the stop-by candidate facility according to the flowchart of FIG. The data is stored in the data storage unit 31 as history information in association with the candidate facility. At this time, for example, when the system controller 20 determines that the vehicle has stopped for a predetermined time or more at the position indicated by the location information of the drop-off candidate facility stored in the map data based on the location information based on the output of the GPS receiver 18 or the like. It is determined that the facility has stopped by. When the system controller 20 executes the flowchart of FIG. 3 again, the system controller 20 refers to the history information described above before executing step S104. Then, when the system controller 20 determines that the facility to be visited is a facility that has been informed in the past as a facility to be visited by the same destination, the system controller 20 guides the facility to be visited in step S104. The process of the flowchart is finished without. By doing in this way, the navigation apparatus 1 can suppress suitably the unnecessary alerting | reporting of the drop-in candidate facility which a user does not need.

(Modification 4)
The navigation device 1 may receive input of setting of turning on and off of the guidance function of the stop-by candidate facility corresponding to steps S102 to S104 of FIG. 3 by the input device 60 and store the information of the setting in the data storage unit 31. Good.

  In this case, the navigation device 1 refers to the setting information stored in the data storage unit 31 when executing the flowchart of FIG. 3, and only when the guidance function for the drop-in candidate facility is set to ON, step S102. The process of S104 is executed. On the other hand, the navigation device 1 does not execute the processes of steps S102 to S104 when the guidance function of the stop-by candidate facility is set to OFF.

(Modification 5)
In the second embodiment, the navigation device 1 does not need to provide guidance regarding the drop-in candidate facility when the facility searched as a drop-in candidate facility is within walking distance (for example, within 500 m) from the destination. Thereby, the navigation apparatus 1 can suppress suitably performing guidance regarding an unnecessary drop-off candidate facility.

(Modification 6)
The navigation device 1 may determine a drop-in candidate facility to be searched based on traffic information regarding a route to the destination.

  For example, if the navigation device 1 determines that there is a traffic jam on the route to the destination based on the traffic information received by the communication device 38 from the VICS center or the like, the route regardless of whether there is a toilet at the destination. Search nearby facilities with toilets as drop-in candidate facilities. And the navigation apparatus 1 performs notification which recommends it to a user by making the searched stop-by candidate facility into a stop-by place. Also by this, the navigation apparatus 1 can notify suitably the drop-in candidate facilities that are useful for the user.
