  By the way, as described above, the navigation device 1 has a function of searching for a route to the destination and guiding the searched route. Here, the user performs a specific action (hereinafter referred to as “desired action”) in a specific area (hereinafter referred to as “route area KA”) during the route guidance to the destination by the navigation device 1. You may want to do that. For example, when there is an area famous for local cuisine near the destination, the user may wish to have a meal in the area before reaching the destination. Based on the user's desire as described above, the navigation device 1 according to the present embodiment is configured to be able to input the desired action and the via area KA, and the desired action inputted in the inputted via area KA. The route through the facility that is the route passing through the corresponding facility that is the facility that can perform the search is searched, and the route guidance using the searched route through the facility is executed. Hereinafter, the operation of the navigation device 1 will be described in detail.

  FIG. 2 is a flowchart showing the operation of the navigation device 1 from when the destination is set by the user until the route to the destination is guided.

  When setting the destination by the user, the input unit 21 of the control unit 2 displays a user interface for receiving the destination input on the touch panel 4. In the user interface, a desired input can be performed in various ways. For example, the destination is input by inputting the address of the destination, or by selecting a position corresponding to the destination on the map displayed on the touch panel 4 and registered in advance. This is done by selecting from the selected destination.

  As shown in FIG. 2, when the user inputs a destination to the user interface, the input unit 21 sets the destination based on the input (step SA1).

  Next, the search unit 22 of the control unit 2 searches for a recommended route R from the current position (departure point) of the vehicle to the destination set by the input unit 21 (step SA2). In the present embodiment, the recommended route R is the route with the lowest link cost among the routes from the departure point to the destination. The map data 3a has information regarding the link cost for each link, and the search unit 22 searches for the recommended route R based on the information included in the map data 3a.

  Next, the route guide unit 24 of the control unit 2 starts guiding the recommended route R searched by the search unit 22 in step SA2 (step SA3). Specifically, the route guidance unit 24 displays a map on the touch panel 4, displays the current position of the vehicle estimated by the position estimation unit 23 on the map, and displays the recommended route R, so that the vehicle is the recommended route. Guiding to drive R.

FIG. 3 is an example of a display screen displayed on the touch panel 4 during the guidance of the recommended route R by the route guidance unit 24.
In the example of FIG. 3, a map is displayed on the substantially right half of the screen, a recommended route R is displayed on the map, and a current position M of the vehicle is displayed. In addition, in the substantially left half of the screen, in order to travel on the recommended route R, information on an intersection at which the vehicle will next turn right and left is displayed. The route guidance unit 24 displays the screen illustrated in FIG. 3 and performs guidance of the recommended route R.

  After starting the guidance of the recommended route R, the input unit 21 monitors whether or not the via area KA and the desired action have been set (step SA4). Hereinafter, the process of step SA4 will be described in detail.

  As shown in FIG. 3, during the guidance of the recommended route R, the touch panel 4 displays a button B1 that can be touch-operated. The button B1 is a button operated when the display screen is changed to the via area KA and an input screen (FIG. 4) on which a desired action can be input. As will be described later, since the setting of the via area KA and the desired action is performed with the user's work, the button B1 is displayed when the vehicle is stopped with the brake by the parking brake being effective. Only displayed.

  When detecting that the button B1 has been touched, the input unit 21 displays on the touch panel 4 an input screen 101 that is a user interface for setting the via area KA and the desired action.

  FIG. 4 is a diagram illustrating an example of the input screen 101.

  As shown in FIG. 4, the input screen 101 includes an item screen 102 and a map display screen 103.

  The map display screen 103 is a screen for setting the transit area KA. As described above, the transit area KA is an area where the user wishes to perform a predetermined action (desired action) via traveling to the destination.

  At the start of display of the input screen 101, the input unit 21 displays a map centered on the current position of the vehicle on the map display screen 103. The map displayed on the map display screen 103 is displayed in a scrollable state in an arbitrary direction. A pointer P is displayed at the center of the map display screen 103. Even when the map displayed on the map display screen 103 is scrolled, the pointer P is maintained in a state where it is positioned at the center of the screen.

  When setting the transit area KA, the user scrolls the map displayed on the map display screen 103 in a predetermined direction so that the map including the transit area KA is displayed on the map display screen 103. Next, the user adjusts the position of the map displayed on the map display screen 103 and positions the pointer P at the center of the area (= route area KA) that he / she desires to perform a predetermined action. The map display screen 103 in FIG. 4A shows a state where the pointer P is located at the center of the transit area KA. Next, the user performs a touch operation on a via area determination button K1 provided on the item screen 102 for determining the via area KA.

  When detecting that the via area determination button K1 is touched, the input unit 21 sets a predetermined area on the map corresponding to the pointer P as the via area KA. In the present embodiment, the predetermined area corresponding to the pointer P is a square area having a side with a predetermined distance (for example, 2 km) extending north and south and a side extending east and west, with the position corresponding to the pointer P being the center. . In the present embodiment, the size of the via area KA is fixed, but the size may be changed. For example, as shown in FIG. 4 (B), the transit area KA is displayed and a frame A whose size can be changed is displayed on the map displayed on the map display screen 103, and the size of the frame A is changed. Thus, the size of the via area KA may be changed. Further, the predetermined area corresponding to the pointer P is not limited to a square area, and may be, for example, a circular area centered on the position corresponding to the pointer P on the map.

  When the setting of the transit area KA by the above-described method is completed, the user can input a desired action. More specifically, when the setting of the transit area KA is completed, the input unit 21 displays one or more desired action selection buttons K2 on the item screen 102 as shown in FIG. The desired action selection button K2 is provided for each of one or a plurality of desired actions registered in advance, and the user performs a desired operation by touching the desired action selection button K2 corresponding to the desired action desired to be performed by the user. You can enter actions.

  In the example of FIG. 4C, three types of desired behaviors “dine”, “buy souvenir”, and “rest” are registered in advance as desired behaviors that can be selected by the user. Yes. The desired action selection button K21 is a button corresponding to the desired action “to eat”. When the user desires to eat in the set via area KA, the user performs a touch operation on the button. The desired action selection button K22 is a button corresponding to the desired action “purchase a souvenir”. When the user desires to purchase a souvenir in the set via area KA, the user touches the button. Manipulate. Further, the desired action selection button K23 is a button corresponding to the desired action “break”, and when the user desires to take a break in the set via area KA, the user performs a touch operation on the button.

  When detecting that any one of the desired action selection buttons K2 is touch-operated, the input unit 21 sets the action corresponding to the desired action selection button K2 that has been touch-operated as the desired action.

  As shown in FIG. 2, when the route area KA and the desired action are set in step SA4 (step SA4: YES), the search unit 22 sets the route area KA based on the map data 3a. The corresponding facility corresponding to the desired behavior is searched, and the position of each corresponding facility is specified (step SA5). As described above, the response facility is a facility that can perform a desired action. For example, if the desired action is “dine”, it is a restaurant, if the desired action is “buy souvenirs”, it is a souvenir shop, and if the desired action is “break”, it is a coffee shop. It is. Hereinafter, the process of step SA5 will be described in detail.

  The map data 3a has information in which information indicating the location of the facility and information indicating the genre of the facility are associated with each other on the facility existing on the map. Further, the map data 3a has information in which information indicating the desired behavior is associated with information indicating the genre of the facility capable of performing the desired behavior for each registered desired behavior. For example, the map data 3a includes information in which the desired action “dine” is associated with the genre “restaurant”.

  In step SA5, the search unit 22 specifies the genre of the facility corresponding to the desired behavior set by the input unit 21 (hereinafter referred to as “corresponding facility genre”) based on the information included in the map data 3a. Next, the search unit 22 specifies a facility having a specified corresponding facility genre, which is a facility existing in the transit area KA set by the input unit 21 based on information included in the map data 3a. The facility specified here is a corresponding facility. Next, the search unit 22 specifies the position of the corresponding facility for each of the specified corresponding facilities based on the information included in the map data 3a.

  After identifying the position of the corresponding facility, the search unit 22 searches for the route through the facility that is a route passing through the identified corresponding facility in a predetermined manner in the set route area KA in Step SA5 (Step SA6). ). Hereinafter, the facility route search method will be described with two examples.

<First facility route search method>
In the first facility route search method, the search unit 22 searches for a route having a larger number of corresponding facilities passing through the route area KA as the facility route.

  FIG. 5 is a diagram used for explaining the processing in step SA6. In FIG. 5, the transit area KA and the recommended route R are clearly shown on the map. Further, in the description using FIG. 5 below, it is assumed that the set desired action is “dine” and the corresponding genres are “restaurant”, “cafe”, and “bar”. In FIG. 5, corresponding facilities S1 to S7 are the corresponding facilities identified in step SA5. Moreover, in FIG. 5, the characters described in the corresponding facilities S1 to S7 indicate the genre of the corresponding facility. Specifically, “Le” indicates a restaurant, “K” indicates a cafe, and “B” indicates a bar.

  In the first facility route search method, the search unit 22 searches for the facility route as follows. That is, first, the search unit 22 is a route that can enter and exit from the recommended route R in the via area KA and that does not travel the same road more than once. Search as a candidate route. Next, the search unit 22 identifies the route having the largest number of corresponding facilities to pass among the searched candidate routes as the route via the facility. When specifying the route via the facility, the search unit 22 may reflect the travel distance of each candidate route, the travel time of each candidate route, and road attributes (whether the road is easy to travel, etc.).

  For example, as shown in FIG. 5, it is assumed that the search unit 22 searches for two routes, a route SR1 and a route SR2, as candidate routes. The route SR1 is a route that enters the transit area KA via the point I1 and exits outside the transit area KA via the point I2, and includes the corresponding facilities S1, S2, S4, S5, S6, and S7. This is a route that passes through six corresponding facilities. On the other hand, the route SR2 is a route that enters the transit area KA via the point I1 and exits outside the transit area KA via the point I2, and includes three correspondence facilities S1, S3, and S7. A route that passes through the facility. In this case, the search unit 22 sets the route SR1 as a facility route. This is because the route SR1 has more facilities to pass through than the route SR2.

  By searching for a facility route by the first facility route search method as described above, the navigation device 1 can provide a facility route that passes through more corresponding facilities to the user, thereby improving user convenience. Can be improved.

<Second facility route search method>
In the second facility route search method, the search unit 22 searches for a route that reduces the bias of the genre (type) of the corresponding facility passing through the route area KA as the facility route. Hereinafter, the second facility route search method will be described with reference to FIG.

  In the second facility route search method, the search unit 22 searches for the facility route as follows. That is, first, the search unit 22 searches for candidate routes by the same method as the first facility route search method. Next, the search unit 22 identifies the route having the largest number of genre types of the corresponding facilities that pass through among the searched candidate routes as the route via the facility. In specifying the facility route, the search unit 22 may reflect the travel distance of each candidate route, the travel time of each candidate route, and the attributes of the road.

  For example, as shown in FIG. 5, it is assumed that the search unit 22 searches for two routes, a route SR1 and a route SR2, as candidate routes. The route SR1 is a route that passes through corresponding facilities of two types of genres, the genre “restaurant” and the genre “cafe”. On the other hand, the route SR2 is a route that passes through the corresponding facilities of the three types of genres of the genre “restaurant”, the genre “cafe”, and the genre “bar”. In this case, the search unit 22 sets the route SR2 as a facility route. This is because the route SR2 has more types of genres of passing facilities than the route SR1.

  By searching for a facility route by such a second facility route search method, the navigation apparatus 1 can provide a facility route that passes through a corresponding facility of many types of genres to the user. Convenience can be improved.

  Note that the above-described facility route search method is an example, and is not limited thereto. For example, a route that passes more through a corresponding facility of a specific genre specified by the user may be used as the route via the facility. In this case, if the desired action is “meal” and the genre designated by the user is “restaurant”, the route via the facility is a route SR1 in FIG. Moreover, the structure which can switch the search method of an in-facility route according to a user's instruction | indication may be sufficient.

  Returning to the description of the flowchart, after searching for the route via the facility in step SA6, the search unit 22 searches for a second route that is a route from the departure point to the destination via the route via the facility (step SA7). ).

  FIG. 6 is a diagram illustrating an example of the second route R2. FIG. 6 shows the second route R2 when the route SR1 is searched as the facility route in step SA6. As shown in FIG. 6, the second route R2 departs from the recommended route R in the middle of the recommended route R, reaches the transit area KA, passes through the facility transit route in the transit area KA, and then the recommended route. This is a route back to R.

  After searching for the second route R2, the route guide unit 24 of the control unit 2 displays the recommended route R and the second route R2 on the map (step SA8). Here, the recommended route R and the second route R2 are displayed with different colors. Thereby, the user can identify the recommended route R and the second route R2. The second route R2 may be displayed together with the recommended route R from the starting point to the destination, and only the route other than the route that overlaps with the recommended route R in the second route R2 (in the case of FIG. 6, the intersection N1). To the intersection N2 via the facility route may be displayed.

  The route guide unit 24 displays the recommended route R and the second route R2, and then displays the current position of the vehicle estimated by the position estimation unit 23 and continuously performs the guidance of the recommended route R ( Step SA9).

  Next, the route guide unit 24 monitors whether or not the vehicle is located near the set via area KA based on the current position of the vehicle estimated by the position estimation unit 23 and the map data 3a ( Step SA10). For example, the route guide unit 24 determines whether or not the distance between the center position of the transit area KA and the current position of the vehicle is within a predetermined processing distance. Perform discrimination.

  When the vehicle is located in the vicinity of the transit area KA (step SA10: YES), the route guide unit 24 inquires the user whether or not to switch the recommended route from the recommended route R to the second route R2, and based on the response to the inquiry Thus, it is determined whether or not the switching is executed (step SA11).

  FIG. 7 is a diagram illustrating an example of an inquiry mode in step SA11.

  When the current position M of the vehicle is located in the vicinity of the transit area KA, the route guidance unit 24 displays a guidance image Ga for inquiring whether to switch the route to be guided to the user as shown in FIG. To do. As shown in FIG. 7, the guide image Ga is displayed superimposed on the map display screen 104. As described above, the second route R2 is a route that passes through a facility route that is a route that passes through a facility where the desired action can be performed in the route area KA input by the user. Therefore, the guidance image Ga is displayed including a message on whether or not to perform guidance of desired behavior regarding the switching to the second route R2. In FIG. 7, the desired action is “dine”. Further, the guide image Ga includes a button B2 that can be switched to route guidance to the second route R2 by selection, and a button B3 that does not perform switching.

  Returning to the description of step SA11, when the user selects the button B3 in FIG. 7, the route guidance unit 24 determines that the route guidance is not switched to the second route R2 (step SA11: NO), and the processing procedure is step SA4. Return to. At that time, the display of the second route R2 may be stopped.

  On the other hand, when the user selects the button B2 in FIG. 7, the route guidance unit 24 determines to execute the route guidance by switching to the second route R2 (step SA11: YES), and determines the route for executing the route guidance as the recommended route. Switching from R to the second route R2 (step SA12), route guidance for the second route R2 is executed (step SA13). The route guidance unit 24 displays the icon of the corresponding facility together with the second route R2 during the route guidance via the facility.

  Here, when the route guidance unit 24 deviates from the route guided by the vehicle, the route guidance unit 24 notifies the user of the departure by display or / and voice (hereinafter referred to as “route departure warning”). Have When the route to be guided is switched from the recommended route R to the second route R2, the route guidance unit 24 does not perform route deviation notification in the following cases.

  That is, the route guidance unit 24 does not issue a route departure warning even when the vehicle deviates from the recommended route R and travels on the second route R2. Thereby, the user can change the traveling route from the recommended route R to the second route R2 without receiving a route departure warning.

  In addition, the route guidance unit 24 separates the second route R2 from the vehicle even when the vehicle deviates from the second route R2 in the route area KA while guiding the second route R2. When the distance is within a predetermined range (for example, a separation distance of 50 m), the route departure warning is not performed. This is due to the following reason. That is, the fact that the route that the user guides is switched from the recommended route R to the second route R2 means that the user wants to perform the desired action in the transit area KA. When the vehicle deviates from the second route R2 during the guidance of the second route R2, the user finds a facility that can perform the desired action by himself / herself in the via area KA and drives the vehicle toward the facility. there is a possibility. Based on this, even if the vehicle deviates from the second route R2, the user desires by not performing the route deviation warning when the distance between the second route R2 and the vehicle is within a predetermined range. When intentionally deviating from the second route R2 to perform an action, it is possible to suppress unnecessary display of the route departure warning, and the convenience for the user is improved.

  In addition, the route guidance unit 24 does not issue a route departure warning even when the route guidance unit 24 deviates from the second route R2 and is located in the corresponding facility within the route area KA while guiding the second route R2. . Thereby, when the user intentionally places the vehicle in the corresponding facility so as to perform the desired action, it is possible to suppress unnecessary display of the route departure warning, and the convenience for the user is improved.

  During the guidance for the second route R2, the control unit 2 monitors whether or not the guidance for the second route R2 is to be stopped (step SA14). Hereinafter, the process of step SA14 will be described in detail.

  FIG. 8 is a diagram showing a display screen displayed on the touch panel 4 during the guidance of the second route R2. In particular, FIG. 8 shows a display screen after a button B4 to be described later is touched.

  As shown in FIG. 8, during guidance of the second route R2, the route guidance unit 24 displays a button B4 on the display screen. The button B4 is a button that is touch-operated when the user stops guidance on the second route R2 and wants guidance on the recommended route R again. When the button B4 is touched, the route guidance unit 24 displays the guidance image Gb. The guidance image Gb is an image for inquiring whether to cancel the route guidance for the second route R2, and is displayed superimposed on the map display screen 100. Similar to FIG. 7, the guidance image Gb is displayed including a message as to whether or not the guidance of the desired action is to be stopped regarding the switching to the second route R2. In FIG. 8, the desired action is “eat”. The guide image Gb includes a button B5 for canceling the guidance of the second route R2 by selection and a button B6 for not canceling. In step SA14, the route guidance unit 24 determines that the guidance of the second route R2 is to be stopped when the button B5 of the guidance image Gb is selected.

  When it is detected that the user has selected the button B5 and it is determined that the guidance of the second route R2 is to be stopped (step SA14: YES), the route guidance unit 24 recommends from the current position M of the vehicle by the search unit 22. Return to route R and search for return route FR that is a route to the set destination (step SA15). Next, the route guide unit 24 starts guiding the return route FR searched by the search unit 22 (step SA16).

  FIG. 9 is a diagram illustrating an example of the return route FR.

  FIG. 9 illustrates a case where the user ends the desired action at the corresponding facility S1 and selects the button B5 shown in FIG. In this case, using the button B5 as a trigger, the search unit 22 searches for a return route FR that returns from the current position M of the vehicle to the recommended route R and reaches the destination.

  As described above, when the user performs a desired action at the corresponding facility after switching the route to be guided from the recommended route R to the second route R2, or when the route to the corresponding facility is canceled, The guidance can be interrupted to guide the route to return to the recommended route R. For this reason, user convenience is improved.

  The return route FR is a route from the current position M of the vehicle to the destination via the recommended route R, but any route that can return to the recommended route R may be used. That is, for example, in the case of FIG. 9, the search unit 22 may search for a route from the current position M of the vehicle to the intersection N2 as the return route FR. In this case, the route guidance unit 24 switches the route guidance from the return route FR to the recommended route R, starting from the passage of the intersection N2.

  As described above, the navigation device 1 (on-vehicle device) mounted on the vehicle in this embodiment has the storage unit 3 that stores the map data 3a (map information), the desired behavior (behavior), and the desired behavior. An input unit 21 that accepts input of a transit area KA (region) to be performed and a facility that can perform a desired action input to the input unit 21 in the transit area KA input to the input unit 21 based on the map data 3a And a search unit 22 that searches for a route via a facility that is a route passing through the facility.

  As a result, the navigation device 1 can provide a route that passes through the facility where the user can enter the desired action in the route area KA input by the user, in addition to the recommended route R to the destination. Will improve.

  In addition, the search unit 22 according to the present embodiment can search for a route that increases the number of corresponding facilities that pass through the route area KA as a facility route.

  As described above, since the search unit 22 searches for a route having a large number of corresponding facilities that pass through the facility-routed route, the navigation device 1 can provide the user with a facility-routed route that passes through more compatible facilities, which is convenient for the user. Improves.

  In addition, the search unit 22 according to the present embodiment can search for a route that reduces the bias of the type that passes in the route area KA as the facility route.

  Thus, since the search unit 22 searches for a route with a low bias in the type of the corresponding facility passing through the facility route, the navigation device 1 can provide the user with a facility-corresponding route with a low bias in the type of the corresponding facility. User convenience is improved.

  Since the configuration of the navigation device 1 in the second embodiment is the same as that of the first embodiment, illustration and description thereof are omitted.

  Here, there is a case where the user goes to a specific area (via area KA) from the departure place, performs a predetermined action (desired action) in the specific area, and desires to return to the departure place again. . For example, a user may know an area famous for ramen at home by media such as television, leave the house, eat ramen in that area, and wish to return to his home again. Based on the user's wishes as described above, the navigation device 1 according to the second embodiment is configured to be able to input the desired action and the transit area KA, and the corresponding facility in the entered transit area KA Search for a route that passes through the facility. Then, after leaving the departure point, the navigation device 1 searches for a route that returns to the departure point again via the facility route, and guides the searched route. Hereinafter, the operation of the navigation device 1 according to the second embodiment will be described.

  FIG. 10 is a flowchart showing the operation of the navigation device 1 according to the second embodiment. The process shown in the flowchart of FIG. 10 is executed in a predetermined operation mode.

  First, the input unit 21 monitors whether or not the via area KA and the desired action have been set (step SB1). Note that the setting of the transit area KA and the desired action is performed by the setting method described in the first embodiment. When the via area KA and the desired action are set (step SB1: YES), the search unit 22 sets the desired action in the via area KA based on the map data 3a as in the first embodiment. The corresponding corresponding facility is searched and the position of each corresponding facility is specified (step SB2). As described above, the response facility is a facility that can perform a desired action.

  After identifying the position of the corresponding facility, the search unit 22 searches for the route through the facility that is a route passing through the identified corresponding facility in a predetermined manner in the set route area KA in Step SB2 (Step SB3). ). The facility route search method is executed in the same manner as in the first embodiment described above.

  Next, when searching for the route via the facility, the search unit 22 searches the third route R3, which is the route from the departure point to the destination via the route via the facility, with the departure point as the destination (step SB4). ).

  FIG. 11 is a diagram illustrating an example of the third route R3. FIG. 11 shows the third route R3 when the route SR1 shown in FIG. 5 is searched as the facility route in step SB3. That is, in FIG. 11, the facility-routed route is a route with a large number of corresponding facilities that pass through. As shown in FIG. 11, the third route R3 is a route from the departure point to the transit area KA, via the facility transit route in the transit area KA, and then returning to the departure point.

  When the search unit 22 searches for the third route R3 in step SB4, the route guide unit 24 of the control unit 2 displays the third route R3 on the map (step SB5). Here, the third route R3 is displayed in a predetermined color. Thereby, the user can distinguish the other route from the third route R3.

  After displaying the third route R3, the route guidance unit 24 displays the current position M of the vehicle estimated by the position estimation unit 23 and performs route guidance on the third route R3 (step SB6). The route guidance unit 24 displays the icon of the corresponding facility together with the third route R3 when traveling on the route via the facility.

  Here, the route guidance unit 24 determines that the distance between the vehicle and the third route R3 is within a predetermined range, or the vehicle passes through the corresponding facility, as in the first embodiment, during the route guidance in step SB6. If it is, the route deviation warning is not executed. In the case of the third route R3, it is only necessary not to execute the route departure warning only when traveling on the route via the facility. When traveling on the third route R3 excluding the route via the facility, In the case of departure, a route departure warning may be executed even if the separation distance is within a predetermined range.

  During the guidance for the third route R3, the control unit 2 monitors whether or not the guidance for the third route R3 is to be stopped (step SB7). Here, the control unit 2 displays the same guide image Gb as in FIG. 8, and determines whether or not to stop the guidance based on the user's operation. When it is detected that the user has selected the button B6 in FIG. 8 and it is determined that the guidance of the third route R3 is to be stopped (step SB7: NO), the control unit 2 returns the process to step SB6. Note that, for example, even if the user does not perform the operation of canceling the guidance, in this embodiment, since the departure point is the destination, if the vehicle travels according to the third route R3, it can return to the departure point. .

  On the other hand, when it is detected that the user has selected the button B5 in FIG. 8 and it is determined that the route guidance of the third route R3 is to be stopped (step SB8: YES), the control unit 2 uses the search unit 22 to determine the current position of the vehicle. The route from M to the departure point as the destination of the third route R3 is searched again (step SB8). Next, the route guidance unit 24 starts guidance for the searched route again (step SB9).

  As described above, the navigation device 1 according to the present embodiment includes the touch panel 4 that displays a map based on the map data 3a, the position estimation unit 23 that estimates the position of the vehicle, and the vehicle position that the position estimation unit 23 estimates. Is displayed on the map displayed on the touch panel 4, and a route guidance unit 24 for guiding the route is provided. The search unit 22 sets the current position M of the vehicle as the departure place and the destination, and starts from the departure place. The route guide unit 24 searches the touch panel 4 for the third route R3 searched for by the search unit 22 and the current position of the vehicle. The third route R3 is guided on the displayed map.

  Thereby, even when the navigation device 1 does not set the destination, that is, when returning to the departure place again, the navigation device 1 can search for the third route R3 via the facility route and guide the third route R3. Improved convenience. In particular, since the third route R3 is searched with the departure point as the destination, the navigation apparatus 1 can guide the route that can return to the departure point again from the departure point via the facility route, and the user Improved convenience.
