  The history storage unit 102 stores information on a facility when the mobile body stops at a facility around the home. The vicinity of the home is, for example, a position within a predetermined distance or a predetermined time range from the home that can be detoured on the way home. The facility is specifically a unique facility such as a store, a school, a station, a gas station, a park, a gym, a friend's house, and the like. The facility information is the name of the facility and the location information of the facility. Whether or not the user has stopped at the facility may be determined based on, for example, whether or not the vehicle has been parked for a predetermined time or more in the parking lot associated with the facility or the facility.

  The destination setting unit 103 sets a destination. When the home is set as the destination in the destination setting unit 103, the receiving unit 104 receives from the user the selection of the facility that visited the past stored in the history storage unit 102. As a stage before the reception unit 104 receives a selection from the user, the notification unit 106 notifies whether or not the user passes through a facility visited in the past.

  When the reception unit 104 receives a facility selection, the search unit 105 searches for a route to the home using the facility as a stopover. The searched route is notified by the notification unit 106 using voice and a display screen.

  Further, in the present embodiment, the history storage unit 102 may store a time zone when a mobile object stops at a facility around the home together with information on the facility. The time zone is classified into, for example, early morning, morning, noon, evening, night, and midnight. This classification is not limited to the time zone, and may be a classification for each day of the week or a classification such as weekdays or holidays. It is also possible to classify by user.

  In this configuration, when the home is set as the destination, the reception unit 104 selects a facility that is stored in the history storage unit 102 and has visited the current time zone or the expected arrival time zone at home. Accept. The estimated arrival time at home may be, for example, an approximation when traveling at a preset speed over a straight line distance from the current position to the home.

  Further, in the present embodiment, the history storage unit 102 may store the number of times the facility has been visited together with information on the facility that has visited. The number of times of stopping may be the past cumulative number or the number of times within the most recent predetermined period. In this configuration, the accepting unit 104 accepts selection of a facility that has been stored in the history storage unit 102 and has visited more than a predetermined number of times when the home is set as the destination.

  In the present embodiment, the reception unit 104 may be able to receive selection of a plurality of facilities from the facilities stored in the history storage unit 102. In this case, when the reception unit 104 receives selection of a plurality of facilities, the search unit 105 stops the plurality of facilities in a predetermined order and searches for a route to the home.

In step S201, it is in a standby state until the home is set as the destination (step S201: No loop). In step S201, when the home is set as the destination (step S201: Yes), it is determined whether or not a facility selection has been received from the user (step S202).

  In step S202, when it is determined that the facility selection has been received from the user (step S202: Yes), the route to the home is searched using the facility as a stopover (step S203), and the series of processing ends. On the other hand, when the selection of the facility is not accepted from the user (step S202: No), the route to the home where there is no drop-in place is searched (step S204), and the series of processing ends.

  As described above, when the home is set as the destination, the route search device 100 according to the present embodiment uses the facility as a stop-by place when a selection of a stored facility is received from the user. The route to the home was searched. Therefore, when setting a stop-by place on the route to return home, it is possible to set the stop-by place easily and quickly without performing complicated operations such as scrolling the screen.

  Also, when a mobile object stops at a facility around the home, it stores the time zone that it stopped with the information on the facility, and when the home is set as the destination, the current time zone or expected arrival at home By accepting the selection of facilities that have stopped by during the time period, it is possible to search for a stop-by place according to the time period. Therefore, the user can set a facility that has stopped at a similar time zone as a stop-by place with a simple operation.

  Also, if you store information on the facility you visited and the number of times you visited the facility, and when your home is set as your destination, you can accept selections of facilities that you have visited more than a certain number of times. You can search for facilities that you have visited. Therefore, the user can set a facility that stops frequently as a stop-by place with a simple operation.

  In addition, the selection of a plurality of facilities from the stored facilities can be accepted, and when the selection of a plurality of facilities is accepted, the plurality of facilities are visited in a predetermined order to search for a route to the home. By doing so, it is possible to set a plurality of facilities as stops by simple operations.

  Also, if a facility is registered in advance as a stop-by location based on input from the user, and the home is set as the destination, selection of the registered facility can be accepted. Can be set with a simple operation.

(Example of route search processing performed by the navigation device)
Next, an example of route search processing performed by the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart illustrating an example of route search processing performed by the navigation device 300 according to the present embodiment.

  In FIG. 4, the navigation apparatus 300 determines whether or not the home is set as the destination (step S401). Details of the display screen in step S401 will be described later with reference to FIG. In step S401, it is in a standby state until the home is set as the destination (step S401: No loop). In step S401, when the home is set as the destination (step S401: Yes), it is determined whether there is a facility that has visited more than a predetermined number of times (step S402).

  If it is determined in step S402 that there is a facility that has visited more than a predetermined number of times (step S402: Yes), it is determined whether or not there is a facility that has stopped in the current time zone (for example, at night) (step S403). ). If it is determined in step S403 that there is a facility that has stopped by in the current time zone (step S403: Yes), the corresponding facility is notified (step S404). Details of the screen notified in step S404 will be described later with reference to FIG.

  And it is judged whether it was selected as a stop-in place (step S405). If it is selected as a stop-in place in step S405 (step S405: Yes), it is determined whether there are a plurality of selected facilities. (Step S406). If it is determined in step S406 that there are a plurality of selected facilities (step S406: Yes), a route to the home where the facilities stop in a predetermined order is searched (step S407). The predetermined order is, for example, the order close to the current position. The route screen searched in step S407 will be described later with reference to FIG.

  Thereafter, the route that has been searched for is guided (step S408). And it is judged whether it arrived at home (step S409). In step S409, the process proceeds to step S408 until the arrival at the home (step S409: No). When the arrival at the home (step S409: Yes), the series of processes is terminated.

  On the other hand, when it is determined in step S406 that there are not a plurality of selected facilities (step S406: No), that is, when there is one selected facility, a route to the home where the facility stops is searched (step S410). ), The process proceeds to step S408.

  In step S405, when it is not selected as a stopover place (step S405: No), a route to a home without a stopover place is searched (step S411), and the process proceeds to step S408. The route screen searched in step S411 will be described later with reference to FIG.

  In Step S402, when it is determined that there is no facility that has visited more than a predetermined number of times (Step S402: No), the process proceeds to Step S411. In Step S403, when it is determined that there is no facility that has stopped in the current time zone (Step S403: No), the process proceeds to Step S411.

  Although details will be described later with reference to FIG. 8, when the user presses and holds a button such as “Return to Home” in the setting of the destination to the home shown in Step S401, the process returns to Step S411. You may make it transfer. Supplementing the specific process, after the process of step S401, it is determined whether or not the button has been pressed for a predetermined time or more, and if the button has been pressed for a predetermined time or more, the process proceeds to step S411. On the other hand, if the button is not pressed for a predetermined time or longer, the process may proceed to step S402.

  In the above-described processing, the order of step S402 and step S403 is arbitrary, and both may be interchanged. Further, in step S403, it may be determined whether or not there is a facility that has visited in the same time zone as the estimated arrival time zone to reach home. In this case, the estimated arrival time at home may be an approximate value when traveling at a preset speed, for example, a linear distance from the current position to the home.

  According to the above-described processing, when the home is set as the destination, when the stored facility selection is accepted from the user, the route to the home is searched using the facility as a stop When setting a stop-by place on the route to return home, it is possible to easily and quickly set a stop-off place without performing a complicated operation such as scrolling the screen.

  Also, when a mobile object stops at a facility around the home, it stores the time zone that it stopped with information on the facility, and when the home is set as the destination, it arrives at the current time zone or home Since the selection of facilities that have stopped by in the expected time zone is accepted, it is possible to search for a stop-by location according to the time zone. Therefore, the user can set a facility that has stopped at a similar time zone as a stop-by place with a simple operation.

  Also, the number of visits to the facility is stored along with the information on the facility visited, and when the home is set as the destination, the selection of the facility that has visited more than a predetermined number of times is accepted. You can search for facilities that you have visited. Therefore, the user can set a facility that stops frequently as a stop-by place with a simple operation.

  In addition, the selection of a plurality of facilities from the stored facilities can be accepted, and when the selection of a plurality of facilities is accepted, the plurality of facilities are visited in a predetermined order to search for a route to the home. Therefore, it is possible to set a plurality of facilities as stop-by places with a simple operation.

(An example of processing to register a stopover location based on the driving history)
Next, an example of processing for registering a stop-on place based on the travel history performed by the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart illustrating an example of a process of registering a stop-on place based on the travel history. In FIG. 5, it is assumed that the stop-in location registration screen (see FIG. 13) is displayed.

  In FIG. 5, the navigation device 300 determines whether or not “search from travel history” is selected (step S501). In step S501, it is in a standby state until "Search from travel history" is selected (step S501: No loop). In step S501, when “Search from travel history” is selected (step S501: Yes), travel history information is acquired (step S502). Then, the facilities around the home that have visited more than a predetermined number of times in the past are extracted (step S503). Note that the number of times of arrival in the past is, for example, the number of times within the latest predetermined period.

  Furthermore, it classify | categorizes for every time slot | zone which reached the said facility (step S504). Thereafter, notification is made as to whether or not the facility is registered as a stop-in place (step S505). Details of the screen notified in step S505 will be described later with reference to FIG. After that, when “Yes” is selected (step S506: Yes), the facility is registered as a stop-by place for each time zone (step S507), and a series of processing is ended.

  On the other hand, if “yes” is not selected in step S506 (step S506: No), that is, if “no” is selected, a series of processing ends. Details of the registered facility will be described later with reference to FIG.

  According to the above-described processing, the vehicle travel history information is acquired, and based on the travel history information, the facilities around the home that have reached the past in a large number of times are extracted, and the vehicles are classified by time zone, Since it is registered on the ground, when returning home, it is possible to register the facility most likely to stop by as a stop-in place in consideration of the time zone. In addition, the user can save the trouble of having to search for a stopover from the map screen, etc., and can easily register the stopover and use the user's own judgment. A desired stop-off place can be registered.

(An example of processing to register a stopover location based on vehicle parking)
Next, an example of a process of registering a stop-on place based on vehicle parking performed by the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating an example of a process of registering a stop-on place based on vehicle parking.

  In FIG. 6, the navigation apparatus 300 determines whether or not the current position is around the home (step S601). In step S601, it is in a standby state until the current position is around the home (step S601: No loop). In step S601, when the current position is around the home (step S601: Yes), it is determined whether or not the vehicle is parked at the facility (step S602). Note that details of the screen displayed in step S602 will be described later with reference to FIG.

  In step S602, when it is determined that the vehicle is parked at the facility (step S602: Yes), it is determined whether a predetermined time has elapsed (step S603). If it is determined in step S603 that a predetermined time has elapsed (step S603: Yes), a notification is sent as to whether or not the facility is registered as a stop-in place (step S604). Note that the elapse of the predetermined time in step S603 includes a state in which the engine is turned off. In this case, the notification in step S604 is notified after the engine is restarted. Details of the screen notified in step S604 will be described later with reference to FIG.

  In step S604, it is determined whether or not “yes” is selected (step S605). If it is determined in step S605 that “Yes” has been selected (step S605: Yes), the facility is registered as a stopover in the current time zone (for example, at night) (step S606), and a series of processing ends. .

  On the other hand, in the case where parking is not performed at the facility in step S602 (step S602: No), the series of processes is terminated. In step S603, if the predetermined time has not elapsed (step S603: No), it is determined whether or not the vehicle has started (step S607). In step S607, until the vehicle starts (step S607: No), the process proceeds to step S603, and when the vehicle starts (step S607: Yes), a series of processing ends. In step S605, if “yes” is not selected (step S605: No), that is, if “no” is selected, a series of processing ends. Details of the registered facility will be described later with reference to FIG.

  According to the above-described processing, when the vehicle is parked at a facility around the house and a predetermined time has elapsed, the user is notified whether or not to register the facility in the stoppage area. It is possible to save the trouble of having to search and register a stop-by place on the map screen or the like, and to easily register the stop-off place.

(An example of processing to register a stopover when setting a registration location)
Next, an example of a process of registering a stop-off place when setting a registration place performed by the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 7 is a flowchart illustrating an example of processing for registering a stop-off place when setting a registration place. The registered place is a facility that is arbitrarily set, for example, a facility that the user wants to mark.

  In FIG. 7, the navigation apparatus 300 determines whether or not a registration location is set (step S701). Details of the registration location setting screen will be described later with reference to FIG. In step S701, it is in a standby state until a registration place is set (step S701: No loop). In step S701, when a registered place is set (step S701: Yes), a notification is made as to whether or not to register the registered place as a stop-in place (step S702).
