JP5773202B2 - Navigation system, navigation program, and navigation method - Google Patents

Description

  The present invention relates to a navigation system, a navigation program, and a navigation method capable of searching for both a vehicle route and a pedestrian route.

  A navigation system capable of searching both a movement route by a plurality of moving means, for example, a vehicle route using a vehicle as a moving means and a pedestrian route using walking (including use of public transportation) as a moving means. Has been put to practical use. For example, Japanese Patent Laying-Open No. 2010-204115 (Patent Document 1) discloses a navigation system that includes a route search server and a mobile terminal device, and performs a route search according to a moving means selected by the mobile terminal device. Yes. This navigation system does not reset the final destination, even if you change the means of travel during route guidance or search for an intermediate destination, and return to the original destination (final destination). The route is searched again (paragraphs 47 to 56, etc.).

  More specifically, this navigation system is configured to include two applications: a pedestrian navigation application for searching for a pedestrian route and a vehicular (passenger seat) navigation application. The user can switch between these two applications. For example, the user sets a final destination (first destination) with any application selected. When it is preferable to use a plurality of means of transportation to this final destination, for example, the vehicle travels to a parking lot on the way and travels from the parking lot to the final destination by foot including the use of public transportation. If it is preferable to do so, the parking lot is set as the second destination. The user first uses the vehicle navigation application to search for a route to the parking lot that is the second destination, and receives guidance information. If the user (vehicle on which the user is boarding) reaches the parking lot or switches the application to the pedestrian navigation app before reaching the parking lot, the pedestrian navigation app is not required to reset the final destination. Searches for a pedestrian route from the current position to the first destination (final destination).

  The navigation system described in Patent Document 1 is an excellent system capable of searching for both a vehicle route and a pedestrian route, but it is necessary to switch applications in order to search each route. That is, when the vehicle (passenger seat) navigation application is activated, the vehicle route is searched, and when the pedestrian navigation application is activated, the pedestrian route is searched. For this reason, it is difficult for the user to search for the entire route in which the vehicle route and the pedestrian route are combined in advance and to refer to the entire route before departure.

JP 2010-204115 A

  In view of the above background, the vehicle route and the pedestrian route included in the entire route from the search start position to the final destination can be appropriately distinguished and searched without selecting the application for which the moving means is specified. Is desired.

The characteristic configuration of the navigation system according to the present invention in view of the above problems is as follows.
A navigation system capable of searching for both a vehicle route and a pedestrian route,
A plurality of search destinations can be set by specifying the order of passage from the search start position, and a destination setting unit that can be set by selecting the type of the search destination from a plurality of types;
A route search unit that performs a route search along the route order from the search start position to the last search destination in the route order,
As the search destinations of different types, a parking destination indicating a destination for parking the vehicle, a walking destination indicating a pedestrian destination starting from the parking destination, the parking destination and the walking And normal destinations that indicate normal destinations that do not belong to any of the destinations,
The route search unit searches the vehicle route from the search start position and the normal destination as a starting point, using the normal destination or the parking destination after the transit order as the search destination. , Searching the pedestrian route using the parking destination as a starting point, the walking destination as the search destination,
The destination setting unit-out based on the type of the search destination that has been set up to date,
When the search destination set to the latest is the normal destination, the type of the other search destination is maintained,
If the most recently set search destination is the parking destination, and another search destination is set immediately after the parking destination in the route order, the other search destination is Set as the walking destination,
When the search destination set most recently is the walking destination, and another search destination is set immediately before the walking destination in the route order, the search destination of the other search destination is set. The point is to set the type as the parking destination . The setting of the type of the search destination by the destination setting unit includes a change of the type of the search destination that has already been set, that is, resetting.

  According to this characteristic configuration, it is possible to set a plurality of search destinations by designating the route order in the entire route from the search start position to the final destination. These types of search destinations are selected and set from a plurality of types by the destination setting unit. And a route for a vehicle and a route for pedestrians are appropriately distinguished and searched by the route search unit according to different types of search destinations. In this search, in order to properly distinguish the vehicle route and the pedestrian route, it is required to appropriately set the type of the search destination. According to this feature configuration, based on the type of the latest set search destination, at least one of the search destination types immediately before and immediately after the search destination route order is appropriately set by the destination setting unit. Is set. Accordingly, it is possible to appropriately distinguish and search the vehicle route and the pedestrian route included in the entire route from the search start position to the final destination without selecting the application for which the moving means is designated. .

Here, since the parking destination is a destination where the vehicle is parked and the walking destination is a pedestrian destination starting from the parking destination, the parking destination and the walking destination are highly related. On the other hand, since the normal destination is a normal destination that does not belong to either the parking destination or the walking destination, the relevance to other normal destinations as well as the parking destination and the walking destination is low. Therefore, the destination setting unit determines that the latest set destination is the parking destination or the walking destination, as described above , based on the type of the latest set destination. Sets the type of at least one of the search destinations immediately before and immediately after the search destination in the order of passage, and if the search destination set to the latest is the normal destination, It is preferable to maintain the type of the search destination.

Further, when the latest set search destination is a parking destination, it is assumed that the user gets off the vehicle at the search destination. When another search destination is set immediately after this search destination (parking destination), the user's means of moving to the other search destination includes the use of public transportation. The possibility of walking is increased. Therefore, as described above, the destination setting unit sets the most recently set search destination as the parking destination, and sets another search destination immediately after the parking destination in the route order. In such a case, it is preferable to set the other search destination as the walking destination.

On the other hand, if the most recently set search destination is a walking destination, the user parked the vehicle somewhere and included the use of public transportation until the search destination (walking destination). There is a high possibility of moving on foot as a means of movement. When another search destination is set immediately before this search destination (walking destination), the user is more likely to get off the vehicle at the other search destination. Therefore, as described above, the destination setting unit sets the most recently set search destination as the walking destination, and sets another search destination immediately before the walking destination in the route order. If it is, it is preferable to set the type of the other search destination as the parking destination.

  Here, when another search destination is not set immediately before the above-described search destination (walking destination), it is conceivable that the location where the user gets off the vehicle is not set. Therefore, as one preferable aspect, the destination setting unit of the navigation system according to the present invention is configured such that the latest set search destination is the walking destination, and immediately before the walking destination in the route order. If another search destination is not set, a parking lot existing within a predetermined range from the walking destination based on a predetermined condition is set as the parking destination in the order of the walking. It is good to set it just before.

By the way, as described above, the destination setting unit is configured to automatically set at least one of the immediately preceding and immediately following search destination types based on the latest set search destination type. However, it may be configured to ask the user to make a decision for this setting. As one preferable aspect, the navigation system according to the present invention includes:
A navigation system capable of searching for both a vehicle route and a pedestrian route,
A plurality of search destinations can be set by specifying the order of passage from the search start position, and a destination setting unit that can be set by selecting the type of the search destination from a plurality of types;
A route search unit that performs a route search along the route order from the search start position to the last search destination in the route order,
As the search destinations of different types, a parking destination indicating a destination for parking the vehicle, a walking destination indicating a pedestrian destination starting from the parking destination, the parking destination and the walking And normal destinations that indicate normal destinations that do not belong to any of the destinations,
The route search unit searches the vehicle route from the search start position and the normal destination as a starting point, using the normal destination or the parking destination after the transit order as the search destination. , Searching the pedestrian route using the parking destination as a starting point, the walking destination as the search destination,
The destination setting unit sets the type of at least one of the search destinations immediately before and immediately after the search destination based on the type of the search destination set most recently. ,
Before SL destination setting unit, a is the search destination set to the latest the parking destination, when another of the search destination immediately after the parking destination is set in the visiting order is If the user is notified to determine whether or not to set the other search destination as the walking destination, and receives the determination to set from the user, the other search destination Is set as the walking destination, and when the determination is received from the user that it is not set, the user may be notified of the setting of the search destination as the walking destination.

  Similarly, when the latest set search destination is a walking destination, it is preferable that the following is configured when setting the type. That is, as one preferable aspect, the destination setting unit of the navigation system according to the present invention is configured such that the latest set search destination is the walking destination, and immediately before the walking destination in the route order. If another search destination is set, the user is notified to determine whether to set the other search destination as the parking destination, and the setting from the user is performed. If the decision to do is received, the other search destination is set as the parking destination, and if the decision not to set is received from the user, the search destination of the parking destination is set. The user may be notified of the setting.

  By the way, since the vehicle is parked at the parking destination, the user who has moved from the parking destination to the walking destination usually returns to the parking destination and gets on the vehicle. Therefore, as one preferable aspect, the route search unit of the navigation system according to the present invention is configured to walk the reciprocating movement route from the parking destination to the parking destination via the walking destination. It is good to search as a user route.

  Various technical features of the navigation system according to the present invention described above can be applied to a navigation program and a navigation method. Therefore, the present invention can also cover such a navigation program and navigation method.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, an in-vehicle navigation system 1 shown in FIG. 1 will be described as an example of a navigation system capable of searching for both a vehicle route and a pedestrian route. The in-vehicle navigation system 1 can be linked with a mobile navigation system 5 mounted on a mobile terminal 3 such as a mobile phone such as a smartphone or a PDA (personal digital (data) assistant). The mobile navigation system 5 is preferably provided as an application (application program) that runs on the mobile terminal 3.

  In the present embodiment, the in-vehicle navigation system 1 searches for a route search for both the vehicle route and the pedestrian route based on the destination information specified by the user. Here, the vehicle route is a route that targets the vehicle, and the pedestrian route includes pedestrians that move using public transportation such as railroads and buses, and is intended for guiding pedestrians. It is a route. The in-vehicle navigation system 1 transmits at least a route for pedestrians to the mobile navigation system 5 that cooperates. The mobile navigation system 5 guides the pedestrian to the destination based on the pedestrian route. The in-vehicle navigation system 1 and the mobile navigation system 5 that cooperate in this way are collectively referred to as a multi-navigation system 7.

  For example, when a user who travels to a parking lot B using a vehicle and plans to walk from the parking lot B to the final destination A uses the multi-navigation system 7, the final destination A, A parking lot B for parking the vehicle is set. The in-vehicle navigation system 1 constituting the multi-navigation system 7 searches for a vehicle route from the departure point C (guidance start position) to the parking lot B, and searches for a pedestrian route from the parking lot B to the final destination A. To do. When the user arrives at the parking lot B, the in-vehicle navigation system 1 and the mobile navigation system 5 (the portable terminal 3) are connected by, for example, short-range wireless communication or cable communication. Thereby, the route for pedestrians is transferred from the in-vehicle navigation system 1 to the mobile navigation system 5. The user gets off with the portable terminal 3 and moves from the parking lot B to the final destination A with reference to the guidance from the mobile navigation system 5 based on the pedestrian route.

  For example, when both the in-vehicle navigation system 1 and the mobile navigation system 5 are constructed in a device that can be attached to and detached from the vehicle, the multi-navigation system 7 may be configured by a single device. Hereinafter, such a device that can be attached to and detached from the vehicle is referred to as a portable navigation device. For example, when the user arrives at the parking lot B, the user removes the portable navigation device from the vehicle and carries the device to the final destination A. In such a case, the multi-navigation system 7 corresponds to a navigation system according to the present invention capable of searching for both the vehicle route and the pedestrian route.

  As shown in FIG. 1, an in-vehicle navigation system 1 that realizes such a multi-navigation system 7 includes an own position specifying unit 11 (vehicle position specifying unit), a navigation calculation unit 12, a user interface unit 16, and a map database. 17 ("database" is represented as "DB" in the drawing including other databases). The navigation calculation unit 12 includes a destination setting unit 13, a route search unit 14, and a guidance information calculation unit 15. The map database 17 includes a road map database 17a, a walking map database 17b, a traffic network database 17c, and a timetable database 17d.

  In the present embodiment, the in-vehicle navigation system 1 is configured with an arithmetic processing device such as a microcomputer or a DSP (digital signal processor) as a core member. That is, each functional unit of the above-described in-vehicle navigation system 1 includes an arithmetic processing unit, a storage medium such as a memory and a disk device, hardware such as a peripheral circuit, and software such as programs and parameters used on the hardware. Realized by collaboration with The same applies to the mobile navigation system 5 described later. That is, each functional unit corresponds to a functional unit in the navigation system of the present invention, corresponds to a “function” in the navigation program of the present invention, and corresponds to an execution unit of “step” in the navigation method of the present invention. For example, the own position specifying unit 11 corresponds to an execution unit for the own position specifying function and the own position specifying step, and the navigation calculation unit 12 corresponds to an execution unit for the navigation calculation function and the navigation calculation step. The destination setting unit 13 corresponds to a destination setting function or a destination setting step execution unit, and the route search unit 14 corresponds to a route search function or a route search step execution unit. Corresponds to an execution unit for a guide information calculation function and a guide information calculation step.

  The navigation calculation unit 12 is a functional unit that is the core of the in-vehicle navigation system 1, and provides route guidance to the destination and self-containment based on the position (local position, vehicle position) where the in-vehicle navigation system 1 (or vehicle) exists. Provide various information at the location. Guidance and information provision by the navigation calculation unit 12 are provided to the user via the monitor device 29, for example. In the case of the portable navigation device as described above, the monitor device 29 may be integrally constructed in the device.

  The own position specifying unit 11 is a functional unit that specifies the own position in order for the navigation calculation unit 12 to perform route guidance to the destination and provide various information at the own position. The self-location specifying unit 11 uses surveying by GPS (global positioning system) or autonomous control by Dead-Reckoning using information acquired by the GPS receiver 21, the direction sensor 22, the distance sensor 23, and the like. And calculate and acquire its own position. When the camera is mounted on the vehicle, the self-position specifying unit 11 captures and recognizes an image of a feature such as a road marking (paint) provided on the road surface in order to improve the position accuracy. May be further added.

  The destination setting unit 13 of the navigation calculation unit 12 is a functional unit that sets a search destination. The destination setting unit 13 can set a plurality of search destinations by specifying the order of passage from the search start position. There are a plurality of types of search destinations, and the destination setting unit 13 can select and set the type of the search destination from the plurality of types. The destination setting unit 13 can also change the already set search destination type to a different type, that is, reset it. Such a change or resetting of the type of the search destination is also included in “setting” by the destination setting unit 13.

  Different types of search destinations include a parking destination indicating a destination for parking the vehicle, a walking destination indicating a pedestrian destination starting from the parking destination, a parking destination, and a walking destination. And a normal destination indicating a normal destination that does not belong to any of the above. In the present embodiment, the normal destination is a search destination for a vehicle route. Although details will be described later, the destination setting unit 13 sets the type of at least one of the search destinations immediately before and immediately after in the route order of the search destination based on the type of the latest search destination. (Including changes and resetting.)

  Based on the search destination set by the destination setting unit 13, the route search unit 14 of the navigation calculation unit 12 uses the vehicle search method from the search start position to the last search destination in the route order along the route order. A route search for a route or a route for pedestrians is performed. Specifically, the route search unit 14 sequentially searches a vehicle route starting from either the search start position or the normal destination as a search destination with the normal destination or the parking destination having a later route order. . In addition, the route search unit 14 searches for a route for a pedestrian using the walking destination as a search destination, starting from the parking destination. Since the vehicle is parked at the parking destination, the user who has moved from the parking destination to the walking destination usually returns to the parking destination and gets on the vehicle. Therefore, it is preferable that the route search unit 14 searches for a reciprocating movement route from the parking destination to the parking destination as a starting point, from the parking destination to the parking destination. Naturally, the route search unit 14 may search only the forward route from the parking destination to the walking destination as the pedestrian route, starting from the parking destination.

  The guidance information calculation unit 15 of the navigation calculation unit 12 performs route guidance to the search destination based on the own position specified by the own position specifying unit 11 according to the route searched by the route search unit 14, particularly the vehicle route here. Provide various information at your location. For example, a route is displayed in a superimposed manner on a road map, a traffic lane division is guided near an intersection, or a traveling direction is guided. The guidance information is provided to the monitor device 29 via the user interface unit 16 and is provided to the user from the monitor device 29. The monitor device 29 is also provided with a speaker, a touch panel, etc., and can provide voice guidance to the user or accept an instruction input from the user. For example, an instruction input such as a search destination setting or a change of the search destination type by the user is transmitted to the destination setting unit 13 via the touch panel and the user interface.

  As described above, the map database 17 includes the road map database 17a, the walking map database 17b, the traffic network database 17c, and the timetable database 17d. The road map database 17a is a database in which information on road networks on which vehicles can mainly travel is stored. For example, in the road map database 17a, connection information between roads (connection points: nodes, roads between connection points: links), road types (types such as highways, toll roads, national roads, prefectural roads), Information such as road length, road shape, and road width is stored. In addition, the road map database 17a stores information on various features (for example, road markings, road signs, traffic lights, signs, overpasses, tunnels, etc.) provided on or around the road, that is, feature information. May be.

  The walking map database 17b is a database in which information on a road network through which pedestrians can mainly pass is stored. Although there is information that overlaps with the road map database 17a, for example, roads that cannot be used by pedestrians, such as automobile-only roads, are excluded from the walk map database 17b. On the other hand, the walking map database 17b also stores information such as railway station premises, underground passages, and promenades where pedestrians can pass even if vehicles cannot pass. The transportation network database 17c is a database that stores connection information of public transportation such as railways, buses, and ferry boats. The timetable database 17d is a database that stores timetables for public transportation. Here, the configuration in which the walking map database 17b, the traffic network database 17c, and the timetable database 17d are separately provided is illustrated. However, for example, the walking map database 17b may be integrated into one. Good.

  The map database 57 used by the mobile navigation system 5 is preferably provided in a server 9 different from the mobile terminal 3. FIG. 1 shows an example in which the map database 57 of the mobile navigation system 5 has a database structure substantially similar to the map database 17 of the in-vehicle navigation system 1. The mobile terminal 3 is preferably configured as a small device in consideration of being carried by the user. In addition, such a portable terminal 3 often has a communication function using a cellular phone network or a wireless communication network. Therefore, it is preferable that the map database 57 used by the mobile navigation system 5 is provided in the server 9 that can communicate with the mobile terminal 3. However, in order to improve convenience and suppress unnecessary communication, for example, a part of road information along the route for pedestrians is downloaded to the mobile terminal 3 and temporarily stored, and this is guided as a database. May be. Preferably, the portable terminal 3 is equipped with a GPS receiver 31 and an electronic compass (not shown). The mobile navigation system 5 provides route guidance to the user based on the position information acquired from the GPS receiver 31 and the electronic compass.

  As described above, when both the in-vehicle navigation system 1 and the mobile navigation system 5 are constructed in one portable navigation device, the database may be switched. For example, when a portable navigation device is mounted on a vehicle, route search and guidance are performed using the map database 17 mounted on the vehicle, and when the portable navigation device is carried by a user outside the vehicle, it is stored in the server 9. Route search and guidance may be performed using the map database 57 that has been made.

  Now, as described above, the in-vehicle navigation system 1 can search for both the vehicle route and the pedestrian route by the route search unit 14. Specifically, the route search unit 14 searches for a vehicle route and a pedestrian route separately based on search destinations of different types. For example, the route search unit 14 searches for a route with reference to different databases based on different types of search destinations. As described above, the type of the search destination is set by the destination setting unit 13. The destination setting unit 13 may set the type of the search destination based on the user's specific instruction, but based on the latest set type of the search destination, the latest set search It is also possible to set (reset) the type of at least one of the search destinations immediately before and after the destination in the route order. More specifically, when the latest set search destination is a parking destination or a walking destination, the destination setting unit 13 immediately before and immediately after the latest set search destination in the route order. The type of at least one of the search destinations is set (reset). On the other hand, the destination setting unit 13 maintains the types of other search destinations when the latest set search destination is a normal destination.

In the following, description will be made using the flowchart of FIG. In step # 10 of FIG. 2, a search destination _Qn is set based on a user instruction. This search destination Q _n is the latest search destination, and is the nth search destination in the order of passage with the search start position set to zero. When searching the destination Q _n is set, then whether the search destination Q _n is parked destination P is determined by the destination setting unit 13 (# 11). When it is determined that the latest search destination Q _n is the parking destination P, it is determined immediately after that, that is, whether or not another search destination Q _{n + 1} is set for the ( _{n + 1} ) th (# 13). . When the (n + 1) th search destination Q _{n + 1} is set, the destination setting unit 13 sets the search destination Q _{n + 1} as the walking destination W.

In other words, as one form, the destination setting unit 13 uses the parking destination P as the _nth search destination Q _n set in the latest via order, and the parking destination P set in the latest in the via order. If the immediately (n + 1 th) another search destination Q _{n + 1} to have been set, the setting the another search destination Q _{n + 1} to the walking destination W (change / reconfiguration) to. If it is determined in step # 13 that the (n + 1) th other search destination Q _{n + 1} is not set, the route search unit 14 performs a route search based on the currently set search destination. (# 50).

Here, a specific example will be shown and described. FIG. 3 shows an example in which one search destination Q is set and a route K is searched from the search start position S to the search destination Q. This search destination Q is the normal destination G, and the route K is the vehicle route M. Here, as shown in FIG. 4, if during the search start position S in FIG. 3 and the search destination Q (usually the destination G), parking destination P is set as the latest search destination Q _n think of. In this case, the latest search destination Q _n is the parking destination P, and another search destination Q _{n + 1} (normal destination G) is set in the ( _{n + 1} ) th immediately after the latest search destination Q _n. Will be. Therefore, the other search destination Q _{n + 1} (normal destination G) is set (changed / reset) as the walking destination W. In this example, the route search unit 14 searches for the vehicle route M (first route K1) using the search start position S as a starting point and the parking destination P as a search destination Q, and starts from the parking destination P as a starting point. The pedestrian route H (second route K2) is searched using the walking destination W as the search destination Q.

In step # 10 of FIG. 2, the search destination Q _n on the basis of a user's instruction set, in step # 11, when the latest search destination Q _n is determined not to be the parking destination P, the following Whether or not the latest search destination Q _n is the walking destination W is determined by the destination setting unit 13 (# 12). When it is determined that the latest search destination Q _n is the walking destination W, it is determined immediately before that, that is, whether or not another search destination Q _n−1 is set for the ( _{n−1) th.} (# 15). When the (n-1) th search destination Q _n-1 is set, the destination setting unit 13 sets the search destination Q _n-1 as the parking destination P.

In other words, as one embodiment, the destination setting unit 13 is a visiting order n-th search destination Q _n walking destination W which is set to the latest, walking destination W which is set to the latest in visiting order If another search destination Q _n-1 immediately before (n-1 th) of (search destination Q _n) is set, the different search destination Q _n-1 of the type parking destination Set to P (change / re-set).

Figure 5 is a visiting order of before the search destination Q (usually the destination G) in FIG. 3 illustrates a case where walking destination W is set as the latest search destination Q _n. In this case, the latest search destination Q _n is the walking destination W, and another search destination Q _n-1 (normal destination G) immediately before the latest search destination Q _n (n−1). Is set. Therefore, in this case, the other search destination Q _n-1 (normal destination G) is set (changed / reset) as the parking destination P. In this example, the route search unit 14 searches for the vehicle route M (first route K1) using the search start position S as a starting point and the parking destination P as a search destination Q, and starts from the parking destination P as a starting point. The pedestrian route H (second route K2) is searched using the walking destination W as the search destination Q.

On the other hand, if it is determined in step # 15 of FIG. 2 that another search destination Q _n-1 is not set immediately before the latest set walking destination W (search destination Q _n ). The destination setting unit 13 sets the parking destination P as a new search destination immediately before the latest set walking destination W in the route order (# 17 in FIG. 2). This parking destination P becomes the search destination Q _n−1 immediately before the latest set walking destination W (search destination Q _n ). Strictly speaking, the n-th search destination Q _n new search destination Q immediately before the (parking destination P) is to be inserted, through the order of n-th search destination Q _n (n + 1) th Thus, the order of passage of the inserted parking destination P is n-th. However, in the present embodiment, in order to express the meaning based on the search destination Q _n set in step # 10, the description will be made using the notations “Q _n ” and “Q _n-1 ” as they are.

  By the way, when setting the parking destination P as a new search destination, the destination setting unit 13 selects a parking lot existing within a predetermined range from the latest set walking destination W based on a predetermined condition. Set as parking destination. Here, the predetermined condition is, for example, within walking distance assumed from a predetermined travel time, within a public transportation section, or the like. Moreover, it is preferable that the predetermined travel time can be set by the user, for example, 30 minutes or 1 hour.

For example, as shown in FIG. 6, the search destination Q (one normal destination G) that has already been set is reset (changed) to the walking destination W, and the search destination Q that is set the latest is set. Consider the case of _n . At this time, a new search destination Q (parking destination P) is set as the search destination Q _n−1 immediately before the walking destination W (search destination Q _n ). Further, there is as shown in FIG. 7, already without the search destination Q that is set, walking destination W is (added) is set as the search destination Q _n which is set to the latest case. In this case, a new search destination Q (parking destination P) is set as the search destination Q _n−1 immediately before the walking destination W (search destination Q _n ). For example, as shown in FIG. 6, when the vehicle route M has already been searched, the parking destination P is determined in consideration of the distance from the vehicle route M and the ease of access. Preferably it is set. In these examples, the route search unit 14 searches the vehicle route M (first route K1) using the search start position S as a starting point and the parking destination P as a search destination Q, and the parking destination P as a starting point. A pedestrian route H (second route K2) is searched using the walking destination W as a search destination Q.

Further, for example, as shown in FIG. 8, although already searched destination Q is set, a search destination Q _{n + 1} immediately after the search destination Q _n to the search destination Q is set to the latest, Even when the immediately preceding search destination Q _n−1 does not exist, the new search destination Q (parking destination P) is the search destination Q _n−1 immediately before the walking destination W (search destination Q _n ). Is set. In this case, as shown in FIG. 8, the parking destination P branches into two routes K, a pedestrian route H to the walking destination W and a vehicle route M to the normal destination G. It will be. Therefore, it is preferable that the vehicle route M from the parking destination P to the normal destination G is the unconfirmed route K ′. In this case, it is preferable that the normal destination G is also the undetermined search destination Q ′. Also in these examples, the route search unit 14 searches the vehicle route M (first route K1) using the search start position S as the starting point and the parking destination P as the search destination Q, and starts from the parking destination P as the starting point. The pedestrian route H (second route K2) is searched using the walking destination W as the search destination Q.

Note that, as described above, the route search unit 14 starts from the parking destination P as a starting point via the walking destination W through the walking destination W and returns to the parking destination P in a round trip route K. It is preferable to search for the use route H. In this case, virtually, the parking destination P is the (n−1) th search destination Q _n−1 and the n + 1th next to the walking destination W that is the _nth search destination Q _n . It may be the search destination Q _{n + 1} . Then, by setting the normal destination G as the (n + 2) -th search destination Q _{n + 2} , the unconfirmed route K ′ can be determined as the determined route K (vehicle route M).

By the way, in step # 12 of FIG. 2 when the latest search destination Q _n is determined not to be a walking destination W, in other words, the latest search destination Q _n, parking even destinations P even walking destination W If not, the search destination Q _n is the normal destination G. In this case, that is, when the most recently set search destination Q _n is the normal destination G, the destination setting unit 13 maintains the types of other search destinations Q.

For example, as shown in FIG. 9, between the search starting position S and the normal destination G, if another normal destination G is set as the latest search destination Q _n, usually purposes already set The place G is the search destination Q _{n + 1} immediately after the latest search destination Q _n . However, since the latest search destination Q _n is the normal destination G, the type of the search destination Q _{n + 1} immediately after being another search destination Q is maintained. Latest search destination Q _n are, first normal destination G1 next accordance visiting order, search destination Q _{n + 1} immediately after the latest search destination Q _n becomes the second ordinary destination G2. Then, the route search unit 14 searches for the first vehicle route M1 (first route K1) with the search start position S as the starting point and the first normal destination G1 as the search destination Q along the route order. Then, the second vehicle route M2 (second route K2) is searched using the first normal destination G1 as the starting point and the second normal destination G2 as the search destination Q.

Such as described above using the flow chart of FIG. 2, the destination setting unit 13, according to the type of search destination Q _n which is set to the latest search destination automatically immediately before Q _n-1 The type of the search destination Q _{n + 1} immediately after or can be set. However, the destination setting unit 13 may be configured to notify the user via the user interface unit 16 that requests determination of whether or not to set.

As one form, the destination setting unit 13 sets the latest search destination Q _n as the parking destination P, and sets the latest parking destination P (search destination Q _n ) in the order of transit. If another search destination Q _{n + 1} is set immediately after, a notification for determining whether or not to set another search destination Q _{n + 1} as the walking destination W is made to the user. Then, when receiving the determination “set” from the user, the destination setting unit 13 sets the other search destination Q _{n + 1} as the walking destination W. On the other hand, when receiving the determination “not set” from the user, the destination setting unit 13 notifies the user of the setting of the search destination Q to be the walking destination W.

For example, the search destination Q is set according to the procedure shown in the flowchart of FIG. Step # 10 and step # 11 in FIG. 10 are the same as in FIG. 2, and step # 21 in FIG. 10 is the same as step # 13 in FIG. In step # 21, if it is determined that there is a search destination Q _{n + 1} immediately after the latest search destination Q _{n (parking} destination P), set the type of search destination Q _{n + 1} immediately after the For example, a notification asking whether or not it is acceptable is output to the monitor device 29 via the user interface unit 16 (# 22). The user inputs an instruction to determine whether or not the monitor device 29 is touchable, for example. The destination setting unit 13 determines a user instruction acquired via the touch panel and the user interface unit 16 (# 23). If the destination setting unit 13 determines that “setting is possible”, the destination setting unit 13 sets the search destination Q _{n + 1} immediately after that to the walking destination W (# 24).

On the other hand, when it is determined that “cannot be set” in step # 23, and when it is determined that “no search destination Qn _{+ 1} immediately after” is determined in step # 21, a notification that prompts the user to set the walking destination W For example, the data is output to the monitor device 29 via the user interface unit 16 (# 25). The user performs an operation for setting the walking destination W similarly to the normal setting of the search destination Q using the touch panel of the monitor device 29, for example. The destination setting unit 13 that has received an instruction from the user via the touch panel and the user interface unit 16 sets the walking destination W (# 26). Then, as described above with reference to FIG. 2, in step # 50, the route search unit 14 searches for the route K.

If it is determined in step # 11 of FIG. 10 that “the latest search destination Q _n is not the parking destination P”, the process proceeds to step # 12 of FIG. 11 via $ 2. This step # 12 is the same as step # 12 in FIG. 2, and is a step following step # 10 and step # 11 in FIG. That is, steps # 10 to # 11 in FIG. 11 and FIG. 2 are the same. Incidentally, the "most recent search destination Q _n parking is the destination P" is determined in step # 11 in FIG. 11, the process proceeds to step # 21 in FIG. 10 via the $ 1. That is, FIG. 10 and FIG. 11 describe one flowchart divided. When "the latest search destination Q _n is a walking destination W" is determined in step # 12, the process proceeds to step # 31.

If it is determined in step # 31 that there is a search destination Q _n-1 immediately before the latest search destination Q _n (walking destination W), the type of the search destination Q _n-1 immediately before For example, a notification asking whether or not to set the value is output to the monitor device 29 via the user interface unit 16 (# 32). The user inputs an instruction to determine whether or not the monitor device 29 is touchable, for example. The destination setting unit 13 determines a user instruction acquired via the touch panel and the user interface unit 16 (# 33). If the destination setting unit 13 determines that “setting is possible”, the destination setting unit 13 sets the immediately following search destination Q _n−1 as the parking destination P (# 34).

When it is determined that “setting is impossible” in step # 33, and when it is determined that “no previous search destination Q _n−1 is present” in step # 31, a notification that prompts the user to set the parking destination P is provided. For example, the data is output to the monitor device 29 via the user interface unit 16 (# 35). The user performs an operation for setting the parking destination P similarly to the normal setting of the search destination Q using the touch panel of the monitor device 29, for example. The destination setting unit 13 that has received an instruction from the user via the touch panel and the user interface unit 16 sets the parking destination P (# 36). Then, as described above with reference to FIG. 2, in step # 50, the route search unit 14 searches for the route K.

  As described above, according to the present invention, the vehicle route and the pedestrian route included in the entire route from the search start position to the final destination are appropriately selected without selecting the application for which the moving means is specified. It is possible to search separately.

  The present invention can be applied to a navigation system, a navigation program, and a navigation method capable of searching for both a vehicle route and a pedestrian route.
