Description

The present invention relates to a movement guidance system that provides movement guidance to a destination.

2. Description of the Related Art In recent years, many vehicles are equipped with a navigation device that guides the vehicle so that the driver can easily arrive at a desired destination. Moreover, some portable terminals owned by users, such as smart phones and mobile phones, have similar functions. Here, the navigation device, which is an in-vehicle device, can provide more detailed and accurate guidance by using vehicle information such as vehicle speed pulses output from the vehicle. The power is turned off, and subsequent guidance cannot be performed. However, there are cases where the destination is far from where the vehicle was parked, and when the destination is a store in a large commercial facility, it is necessary to move around the facility after getting off the vehicle. It may be necessary.

Therefore, in such a case, a method has been proposed in which guidance is handed over from the navigation device to a mobile terminal carried by the user, and guidance is continued using the mobile terminal after the user gets out of the vehicle. For example, Japanese Patent Application Laid-Open No. 2005-3526 calculates the remaining distance from the parking position to the destination when the vehicle is parked, and the remaining distance to the destination is a predetermined distance (for example, 100 m to several kilometers). A technique has been proposed in which a walking route to the destination is searched and transmitted to a mobile terminal when the distance is within the range, and the mobile terminal then provides movement guidance to the destination.

Japanese Patent Application Laid-Open No. 2005-3526 (pages 7-9, FIG. 3)

However, in the technique of Patent Document 1, guidance is handed over from the navigation device to the portable terminal only when the remaining distance to the destination is within a predetermined guidance distance. If the distance to the destination is short, the guidance is not handed over. However, in facilities that include multiple points that can be set as destinations (hereafter referred to as complex facilities), such as large commercial facilities and stations, even if the remaining distance to the destination is short, after getting off the vehicle, It is desirable to continue guidance even after getting off the vehicle.

The present invention has been made to solve the above-mentioned conventional problems, and when any point included in the complex facility is set as the destination, the guidance is handed over from the vehicle-mounted device to the portable terminal. Accordingly, it is an object of the present invention to provide a movement guidance system capable of continuing movement guidance to a destination even after getting off the vehicle.

In order to achieve the above object, the movement guidance system according to the present invention includes an on-vehicle device that guides the travel of a vehicle based on a set route to a destination, and a mobile terminal owned by a user who is a passenger of the vehicle. wherein any point included in a complex facility including a plurality of points that can be set as destinations is set as a destination in the vehicle-mounted device, and the vehicle corresponds to the complex facility parking determination means for determining whether or not the vehicle is parked in the parking lot corresponding to the complex facility; transfer means for transferring the information about the destination to the mobile terminal; and movement guidance means for guiding the movement of the vehicle from the position where the vehicle is parked to the point set as the destination in the mobile terminal that has transferred the information about the destination and have
For example, if the complex facility is a commercial facility, the "point that can be set as the destination" corresponds to the store (tenant) in the facility, and if the complex facility is a station, it is installed in the station premises. This applies to ticket gates.

According to the movement guidance system according to the present invention having the above configuration, when one of the points included in the complex facility is set as the destination and the vehicle is parked, the vehicle is parked. By handing over the information about the destination to , it is possible to continue to provide movement guidance to the destination even after getting off the vehicle. As a result, it is possible to make the user reach the destination without fail even when the user needs to walk around the facility after getting off the vehicle.

Further, the navigation device 3 and the portable terminal 4 are connected at least while the user is in the vehicle 2 by a wired connection such as a USB cable, or wireless communication such as Bluetooth (registered trademark), so that they can transmit and receive data to and from each other. ing. On the other hand, the server device 6, the navigation device 3, and the portable terminal 4 are configured to be able to transmit and receive data to and from each other via the communication network 7. FIG. If all communications between the navigation device 3 and the mobile terminal 4 are performed via the server device 6, there is no need to enable direct communication between the navigation device 3 and the mobile terminal 4. FIG.

Here, the navigation device 3 has a function of identifying the current position such as GPS, a function of searching for a recommended route to a set destination, a function of searching for a recommended route to a set destination, and a function of Vehicle-mounted vehicle with functions to display a map image of the vehicle's current location and its surroundings based on map data, to display the vehicle's current location in the displayed map image, and to perform movement guidance along a set guidance route. machine. It is also possible for the server device 6 to search for a recommended route to the destination.

Further, the navigation device 3 can communicate with various ECUs of the vehicle 2 via an in-vehicle network such as CAN (Controller Area Network). The navigation device 3 can collect data detected by various sensors installed in the vehicle 2 and traveling data via an in-vehicle network or other communication means.

The mobile terminal 4 is an information terminal possessed by the user and provided with a navigation function, and corresponds to, for example, a mobile phone, a smart phone, a tablet terminal, a personal computer, and the like. In this embodiment, a case where the mobile terminal 4 is a smartphone will be described as an example. When the portable terminal 4 is a terminal such as a smartphone capable of executing a plurality of applications, a navigation application is installed as one of the applications. Here, the navigation application is an application that executes a navigation function on the mobile terminal 4 . As the navigation function, it displays a map image around the current position of the mobile terminal 4 (user) based on the map information acquired from the server or stored in the memory. ) to display the current position, search for recommended routes to the set destination, and provide guidance. However, the navigation application does not necessarily have to have all of the above navigation functions.

In particular, in the movement guidance system 1 of the present embodiment, one of the points included in a facility (hereinafter referred to as a complex facility) that includes a plurality of points that can be set as destinations is set as the destination in the navigation device 3. In this case, after it is determined that the vehicle 2 has parked in the parking lot corresponding to the complex facility, the navigation application is activated on the mobile terminal 4, the destination information is inherited from the navigation device 3, and the vehicle is alighted. Then, the user is guided on the walking route to the destination and is guided to move according to the walking route. Details will be described later.

On the other hand, the server device 6 executes route search in response to requests from the navigation device 3 and the mobile terminal 4 . Specifically, when a destination is set in the navigation device 3 or the mobile terminal 4 or when a route is re-searched (rerouted), the navigation device 3 or the mobile terminal 4 sends the origin and the destination to the server device 6. Information necessary for route search, such as the destination, is transmitted together with the route search request (however, in the case of re-search, it is not always necessary to transmit information regarding the destination). Upon receiving the route search request, the server device 6 searches for a route using the map information of the server device 6, and specifies a recommended route from the departure point (parking position of the vehicle for the walking route) to the destination. After that, the specified recommended route is transmitted to the navigation device 3 or the mobile terminal 4 that made the request. Then, the navigation device 3 and the portable terminal 4 provide the user with the received information on the recommended route, set the recommended route as the guidance route, and perform movement guidance according to the guidance route. The server device 6 also provides the navigation device 3 and the mobile terminal 4 with information (for example, map information, parking lot map, floor map, voice data, etc.) necessary for movement guidance as necessary. As a result, even if the map information possessed by the navigation device 3 or the mobile terminal 4 at the time of route search is of an old version, or even if the navigation device 3 or the mobile terminal 4 does not have the map information itself, the server It is possible to provide a recommended route to an appropriate destination based on the latest version of the map information possessed by the device 6 and perform movement guidance.

For example, the parking determination means determines whether the vehicle 2 is parked at the complex facility when one of the points included in the complex facility including a plurality of points that can be set as the destination is set in the navigation device 3 as the destination. It is determined whether or not the vehicle is parked in the garage. The transfer means transfers the information about the destination set by the navigation device 3 to the portable terminal 4 when it is determined that the vehicle is parked in the parking lot corresponding to the complex facility. The movement guide means guides the movement from the position where the vehicle 2 is parked to the point set as the destination in the mobile terminal 4 that has inherited the information about the destination.

The operation unit 14 is operated when inputting a departure point as a travel start point and a destination as a travel end point, and has a plurality of operation switches (not shown) such as various keys and buttons. Then, the navigation ECU 13 performs control to execute various corresponding operations based on switch signals output by pressing of each switch or the like. Note that the operation unit 14 may have a touch panel provided on the front surface of the liquid crystal display 15 . It may also have a microphone and a voice recognition device.

In addition, the liquid crystal display 15 displays a map image including roads, traffic information, operation guidance, operation menu, key guidance, guidance information along the guidance route (planned travel route), news, weather forecast, time, e-mail, TV Programs, etc. are displayed. A HUD or HMD may be used instead of the liquid crystal display 15 .

In addition, the speaker 16 outputs voice guidance for driving along a guidance route (planned driving route) and traffic information guidance based on instructions from the navigation ECU 13 .

Also, the DVD drive 17 is a drive capable of reading data recorded on recording media such as DVDs and CDs. Then, based on the read data, music and video are reproduced, the map information DB 25 is updated, and so on. A card slot for reading and writing a memory card may be provided instead of the DVD drive 17 .

The communication module 18 is a communication device for communicating with the mobile terminal 4, the server device 6, and other information centers (eg, VICS (registered trademark) center, etc.). , Bluetooth modules, etc. In particular, in this embodiment, when any point included in the complex facility is set as the destination in the navigation device 3, and it is determined that the vehicle 2 has parked in the parking lot corresponding to the complex facility. In this case, information on the currently set destination is transmitted to the mobile terminal 4 via the communication module 18 in order to take over the guidance to the mobile terminal 4 .

Next, a schematic configuration of the mobile terminal 4 will be described with reference to FIG. FIG. 3 is a block diagram schematically showing the control system of the mobile terminal 4 according to this embodiment. In addition, below, especially the case where the portable terminal 4 is a smart phone is mentioned as an example, and it demonstrates.

As shown in FIG. 3, the mobile terminal 4 has a data bus BUS, a CPU 41, a memory 42 storing user information (user ID, name, etc.) about the user who owns the mobile terminal 4, and a base of the communication network 7. A transmitter/receiver circuit (RF) 43 that transmits and receives signals to and from the station, and a base that converts the RF (Radio Frequency) signal received by the transmitter/receiver circuit 43 into a baseband signal and converts the baseband signal into an RF signal. A band processing unit 44, an input/output unit 47 which is an interface with a microphone 45, a speaker 46, etc., a display 48 configured with a liquid crystal display panel, etc., an input operation unit 49 configured with a touch panel, hard buttons, etc. It is configured by connecting a GPS 50 , a camera 51 , and a communication module 52 .

Here, the CPU 41 incorporated in the mobile terminal 4 is control means of the mobile terminal 4 that executes various operations according to the operation program stored in the memory 42 , and together with the memory 42 constitutes a mobile terminal control section 55 . Various processing contents of the mobile terminal control unit 55 are displayed on the display 48 as necessary.

Also, the memory 42 is a storage medium in which user information (user ID, name, etc.) related to the user possessing the portable terminal 4 is stored. Various application programs including a movement guidance processing program (FIG. 4), which will be described later, are also stored. Map information may also be stored in the memory 42 . If the map information is stored in the memory 42 , it is possible to perform the processing related to the route search by the portable terminal 4 instead of the server device 6 . Also, the memory 42 may be configured by a hard disk, a memory card, or the like.

Also, the display 48 is arranged on one side of the housing, and a liquid crystal display, an organic EL display, or the like is used. A top screen for executing various applications installed in the mobile terminal 4, screens related to the executed applications (Internet screen, mail screen, etc.), and various information such as images and videos are displayed. In addition, when the navigation application is activated, map information of the surrounding area, the user's current position, and route information are displayed. Particularly, when the user is located inside the facility, a floor map is also displayed.

The input operation unit 49 is configured by a touch panel provided on the front surface of the display 48, hardware buttons arranged on the housing, and the like. Then, the mobile terminal control unit 55 performs control to execute various corresponding operations based on an electric signal output by pressing a touch panel or hardware button. The input operation unit 49 can also be composed of various keys such as number/character input keys, cursor keys for moving a cursor for selecting displayed contents, and decision keys for confirming selections.

Also, the GPS 50 can detect the current position and current date and time of the mobile terminal 4 (that is, the user) by receiving radio waves generated by artificial satellites. In addition to the GPS 50, the configuration may include other devices (for example, a geomagnetic sensor, a gyro sensor, etc.) for detecting the current position and orientation of the mobile terminal 4. FIG.

Also, the camera 51 is a small-sized imaging device configured by a camera using a solid-state imaging device such as a CCD, and is built in the back side of the mobile terminal 4 . With the dedicated application program activated, the user can capture an image of the surroundings by operating the input operation unit 49 . The captured image captured by the camera 51 is stored in the memory 42 .

The communication module 52 corresponds to, for example, an LTE communication module, a WiFi communication module, a Bluetooth module, etc., and is a communication device for transmitting and receiving various information to and from the navigation device 3 . In particular, in this embodiment, when any point included in the complex facility is set as the destination in the navigation device 3, and it is determined that the vehicle 2 has parked in the parking lot corresponding to the complex facility. In this case, information regarding the destination currently set in the navigation device 3 is received via the communication module 52 in order to take over the guidance from the navigation device 3 . Incidentally, the communication with the navigation device 3 can also be performed by wire, and a configuration in which a communication connector such as a USB is provided is also possible.

Next, a movement guidance processing program executed by the navigation device 3 and the portable terminal 4 in the movement guidance system 1 having the above configuration will be described with reference to FIG. FIG. 4 is a flow chart of a movement guidance processing program according to this embodiment. Here, the movement guidance processing program is a program that is executed after the ACC power supply (accessory power supply) of the vehicle is turned on, and performs movement guidance to the destination in the navigation device 3 and the mobile terminal 4 . 4 below is stored in the RAM and ROM provided in the navigation device 3 and the portable terminal 4, and is executed by the CPU 31 or CPU 41. As shown in FIG.

First, the movement guidance processing program executed by the CPU 31 of the navigation device 3 will be described with reference to FIG. In step (hereinafter abbreviated as S) 1, the CPU 31 inputs the destination based on the operation of the operation unit 14 by the passenger of the vehicle. The destination need not be input before the movement to the destination is started, and may be after the movement to the destination is started.

Next, in S2, the CPU 31 searches for a recommended route to the destination in response to the input of the destination in S1. The search for the recommended route may be performed by the navigation device 3 or may be performed by the server device 6 . For example, when the server device 6 is used, when a destination is input in the navigation device 3, the navigation device 3 sends the server device 6 information necessary for a route search, such as a starting point and a destination, together with a route search request. sent. After receiving the route search request, the server device 6 performs a route search using the map information held by the server device 6, and specifies a recommended route from the departure point to the destination. After that, the specified recommended route is transmitted to the navigation device 3 that made the request. Then, the navigation device 3 sets the searched recommended route as a guidance route, and thereafter performs movement guidance according to the guidance route until the destination is reached (S3).

Since the recommended route searched in S2 is the travel route of the vehicle, if the destination set in S1 is "a point that can be set as a destination included in the complex facility", that is, the vehicle If the destination is a point that can only be reached by getting off the bus and moving on foot, the end point of the recommended route will be the arrival point of the complex facility, the parking lot corresponding to the complex facility (the parking lot within the facility, may be a parking lot outside the facility), or an entrance to a parking lot. That is, the walking route to the destination after getting off the vehicle is not included. However, the search target (multimodal search) may also include the walking route to the destination after getting off the vehicle.

Note that the "arrival point" is position coordinates indicating the position of the end of the route on the link when the facility is the destination. For example, the arrival point is the intersection of a perpendicular line drawn from the entrance of the facility or the center of the facility to the link facing the facility and the link.

After that, in S<b>4 , the CPU 31 determines whether the vehicle has reached within a predetermined distance (for example, 50 m) from the end point of the guidance route currently set in the navigation device 3 .

Then, when it is determined that the vehicle has arrived within the predetermined distance from the end point of the guidance route (S4: YES), the process proceeds to S5. On the other hand, when it is determined that the vehicle has not arrived within the predetermined distance from the end point of the guidance route (S4: NO), movement guidance to the destination is continued.

In S5, the CPU 31 determines whether or not the destination currently set in the navigation device 3 is "a point that can be set as the destination included in the complex facility". Here, for example, if the complex facility is a commercial facility, the "points that can be set as destinations included in the complex facility" are shops (tenants) within the facility, and if the complex facility is a station, corresponds to the ticket gates installed in the station premises.

In addition, as a method of determining whether or not the destination currently set in the navigation device 3 is "a point that can be set as a destination included in the complex facility", for example, the following (1) to (3) are given. be done.
(1) Determine based on the name. For example, as shown in FIG. 5, the name of the point currently set as the destination may be divided into the first half and the second half. In such a case, the point is a tenant in a commercial complex, and the latter part often indicates the name of the commercial complex in which the tenant resides. Alternatively, the point may be the ticket gate of the station, and the first half may indicate the name of the station. Therefore, if the name of the point currently set as the destination is divided into the first half and the second half, and one of the names includes the name of one of the complex facilities, then the name of the point that can be set as the destination included in the complex facility ” is determined.
(2) Judgment based on genre. For example, the point data 28 included in the map information DB 25 stores the genre of the point as information on each point that can be set as a destination all over the country. Therefore, genres such as "Tenant in a commercial complex" and "Ticket gate" are set in advance, and if the genre of the point set as the destination falls under those genres, "Destination included in the complex facility" A point that can be set to
(3) Judgment by linking points. For example, as shown in FIG. 6, in the point data 28, a "complex facility" and a "point that can be set as a destination included in the complex facility" are linked in advance. Then, if the point set as the destination is a point linked to any complex facility, it is determined as "a point that can be set as the destination included in the complex facility".

If it is determined that the currently set destination in the navigation device 3 is "a point that can be set as a destination included in the complex facility" (S5: YES), the process proceeds to S6. On the other hand, if it is determined that the destination currently set in the navigation device 3 is not "a point that can be set as a destination included in the complex facility" (S5: NO), the process proceeds to S10. End the movement guidance. Therefore, if the complex facility itself is set as the destination in the navigation device 3 instead of a point included in the complex facility, the navigation device 3 will be able to Guidance ends without handing over the information about the set destination to the mobile terminal 4 .

After that, in S6, the CPU 31 specifies a recommended parking position (hereinafter referred to as a recommended parking position) for parking the vehicle when traveling to the destination. For example, the server device 6 statistically collects the past parking histories collected from each vehicle, and specifies the parking position where the vehicle has been parked many times for each destination point in the past. Then, the navigation device 3 acquires from the server device 6 a parking position where the vehicle has been parked many times by other vehicles that have set the current destination in the past, and specifies that parking position as a recommended parking position. If the destination has a plurality of parking lots, the recommended parking position may be determined in units of parking lots, or more specifically, in units of areas within the parking lot or in units of parking spaces.

Next, at S7, the CPU 31 guides the recommended parking position specified at S6. Specifically, the recommended parking position may be displayed on the liquid crystal display 15 together with the entire map of the parking lot, or the direction of the recommended parking position may be guided by voice. Alternatively, a route in the parking lot from the current position of the vehicle to the recommended parking position may be searched for guidance. Also, in the case of an automatically driving vehicle, parking at the recommended parking position may be performed automatically. At the timing when it is determined that the vehicle has arrived within a predetermined distance from the end point of the guidance route (S4: YES), movement guidance based on the guidance route ends. guidance will be given.

After that, in S8, the CPU 31 determines whether or not the vehicle has parked in the parking lot. Whether or not the vehicle has been parked is determined based on the current vehicle speed, the shift position of the vehicle, and the state of brake operation, which are collected from the vehicle via the CAN. Also, the position where the vehicle is parked does not necessarily have to be the recommended parking position specified in S6, but at least it must be a parking lot corresponding to a complex facility that includes the destination. The “parking lot corresponding to the complex facility” is not limited to the exclusive parking lot of the complex facility, and may be a contracted parking lot or a pay parking lot around the complex facility.

Then, when it is determined that the vehicle has parked in the parking lot (S8: YES), the process proceeds to S9. On the other hand, if it is determined that the vehicle is not parked in the parking lot (S8: NO), it waits until the vehicle is parked.

In S<b>9 , the CPU 31 transmits to the mobile terminal 4 the destination information about the destination currently set in the navigation device 3 in order to take over the guidance from the navigation device 3 to the mobile terminal 4 . For example, the ID of the point set as the destination (common to the navigation device 3 and the portable terminal 4), name, position coordinates, genre, etc. are transmitted. The destination information may be transmitted directly to the mobile terminal 4 or via the server device 6 when the navigation device 3 and the mobile terminal 4 can directly communicate via Bluetooth or the like. good.

After that, in S10, the CPU 31 terminates the movement guidance by the navigation device 3 (including the recommended parking position guidance in S7).

Next, a travel guidance processing program executed by the CPU 41 of the mobile terminal 4 will be described. Each process of S11 to S13 below is started at the timing when the corresponding information from the navigation device 3 is received.

First, in S<b>11 , the CPU 41 receives destination information transmitted from the navigation device 3 . The destination information includes information specifying the destination of the navigation device 3 set by the user in S1 (for example, destination coordinates, ID, facility name, etc.). After that, the navigation application is activated on the mobile terminal 4, and the following processes are performed.

In S12, the CPU 41 searches for a recommended route from the current position (that is, the position where the vehicle is parked) to the destination. The search for the recommended route may be performed by the mobile terminal 4 or may be performed by the server device 6 . For example, when the server device 6 performs the route search, when destination information is transmitted from the navigation device 3, information necessary for route search such as the current position and destination is sent from the portable terminal 4 to the server device 6 as a route search request. sent with The server device 6 that has received the route search request performs a route search using the map information that the server device 6 has, and specifies a recommended route from the current position to the destination. After that, the identified recommended route is transmitted to the mobile terminal 4 that made the request. Then, the portable terminal 4 sets the searched recommended route as a guidance route, and thereafter performs movement guidance according to the guidance route until the destination is reached (S13).

Here, the recommended route searched in S12 is a walking route after getting off the vehicle. Therefore, the mobile terminal 4 or the server device 6, which is the subject of the search for the recommended route, uses, for example, a parking lot corresponding to the complex facility (a parking lot (including stand-alone parking lots), information that identifies the location of entrances and exits to parking lots, information that identifies the layout of parking spaces within parking lots, information on lane markings that separate parking spaces, and information on how vehicles and pedestrians pass It has information about possible passages. For complex facilities, information specifying the floor map of the facility is also included. The floor map includes, for example, information specifying the positions of entrances, exits, passages, stairs, elevators, escalators, and ticket gates in the case of stations. It also includes information specifying the location of each tenant who moves in. In addition, it is also possible to have information generated by 3D models of parking lots and complex facilities in particular.

Details of the recommended route search processing in S12 will be described below. In the following example, it is assumed that the search is performed by the server device 6 .
First, the server device 6 reads detailed information such as the above-described floor map from the DB for a complex facility including a user's destination point and a parking lot where the user parks. Next, we construct an intra-building network, which is a network showing routes that can be selected by means of transportation (on foot) after getting off the vehicle in the building where the destination is located. For example, if the destination is one tenant in a commercial complex with multiple tenants, a network of the entire building of the commercial complex where the destination tenant is located will be constructed. An example of the constructed intra-building network is shown in FIG. In particular, FIG. 7 shows an example in which the destination is one tenant in a multi-tenant commercial facility. As shown in FIG. 7, the intra-building network is constructed using walking nodes 81 and walking links 82 . The walking nodes 81 are set at intersections where pedestrian-accessible passages intersect within the building, end points and corners of pedestrian-accessible passages, entrances and exits of buildings, stairs, elevators, escalators, and the like. . Furthermore, it is also set for the tenant that is the destination and the aisle facing the tenant. On the other hand, the walking link 82 is set for a pedestrian-passable area between the walking nodes 81 . Pedestrian-passable areas include pedestrian-passable passages (including stairs, escalators, crosswalks, pedestrian bridges, and moving walkways). The walking link 82 also has information specifying directions in which pedestrians can travel.

Next, the server device 6 similarly constructs a network for the parking lot where the user parked, and generates a parking lot network. Specifically, in addition to the aisles in the parking lot, the partition lines that separate the parking spaces are also networked as one of the aisles that the user can pass through. In addition, if the parking lot where the vehicle is parked is far from the building where the destination is located, and after parking the vehicle, it is necessary to walk on the road outside the parking lot. do. An example of the constructed parking lot network is shown in FIG. As shown in FIG. 7, the parking lot network is constructed using walking nodes 81 and walking links 82 . The pedestrian node 81 is an intersection where a pedestrian-passable passage (a pedestrian-only passage and a vehicle-passable passage may be included; the same shall apply hereinafter) intersects in addition to the corner of the lane marking. , and are set at the end points and corners of passages through which pedestrians can pass. On the other hand, the walking link 82 is set for a pedestrian-passable area between the walking nodes 81 . Pedestrian-accessible areas include, in addition to pedestrian-accessible paths, pedestrian-only paths (including stairs, escalators, crosswalks, pedestrian bridges, and moving walkways), and parking space divisions. On-line applies. The walking link 82 also has information specifying directions in which pedestrians can travel.

Subsequently, the server device 6 connects the foot node 81 corresponding to the entrance of the building in the constructed intra-building network and the foot node 81 of the nearby parking lot network by a new foot link 82 . It should be noted that the number of connecting foot links 82 does not have to be one, and the number of walking links 82 that can be entered from the parking lot side to the entrance of the building is connected. As a result, the in-building network and the parking lot network are connected as shown in FIG. The network generated in this manner is a network showing routes that can be selected by the user after getting off the vehicle, spanning both areas in the parking lot and the building.

Subsequently, the server device 6 specifies the position of the driver's seat of the parked vehicle (that is, the position where the user gets on and off when the vehicle is parked, hereinafter referred to as the vehicle getting on and off position). It should be noted that whether the user has parked the vehicle facing forward or backward at the parking position candidate is determined, for example, from travel data at the time of parking. Next, the server device 6 specifies the cost and direction (direction in which the walking node can be passed) for the finally constructed network (the one in which the intra-building network and the parking lot network are connected), especially for the walking node 81. set. For example, for each walking node 81 corresponding to an intersection, stairs, elevator, and escalator, a cost corresponding to the content of the walking node 81 is set, and a passable direction when the user passes through the walking node 81 is set. . A cost is also set for the walking link 82 . As for the cost of the walking link 82, the time required for movement on the walking link 82 is used as a reference value. That is, a higher cost is calculated for the walking link 82 that takes longer time to move. The travel time of the walking link 82 is calculated by multiplying the travel speed by the length of the link, and the travel speed is set to a fixed value (for example, 1 m/s) considering the travel speed on foot.

After that, the server device 6 uses the Dijkstra algorithm to search for a route from the vehicle boarding/alighting position to the destination via the entrance of the complex facility. Specifically, the total cost of the walking node 81 and the walking link 82 is calculated for the route connecting the vehicle boarding/alighting position to the destination in the finally constructed network. As a route search method, search means other than the Dijkstra method may be used. Then, the route with the lowest total cost is output from among the routes connecting the boarding/alighting position of the vehicle to the destination via the entrance of the complex facility. The output route is a recommended route that causes the least burden on the user in moving from the parking position to the destination after the user parks the vehicle in the parking lot. For example, FIG. 8 shows an example of a recommended route 85 that is searched when the vehicle is parked in parking space A. In FIG.

In S13, movement guidance is performed based on the guidance route set in the portable terminal 4. As a method of movement guidance, for example, as shown in FIG. A floor map is displayed, and further, a mark 91 indicating the user's current position and a future travel direction 92 along the guide route are displayed. Also, voice guidance may be provided according to the guidance route. Information (for example, parking lot map, floor map, voice data, etc.) necessary for movement guidance can be obtained from the server device 6 as necessary. As a result, the user can reliably reach the destination based on the guidance provided by the portable terminal 4, even if it is necessary to walk around the facility after getting off the vehicle. Become. Note that the parking lot map is displayed until the user enters the complex facility, and the display is switched to the floor map after the user enters the complex facility.

However, if it is difficult to specify the detailed current position of the user in the building due to the accuracy of the GPS of the mobile terminal 4, the movement guidance based on the current position of the user will not be performed, and the floor of the entire building will be displayed. A map, the position of the destination, and the guidance route may be displayed. When the user reaches the destination after that, the mobile terminal 4 terminates the navigation application.

As described in detail above, in the mobile guidance system 1, the navigation device 3, and the portable terminal 4 according to the present embodiment, any point included in a complex facility that includes a plurality of points that can be set as destinations is used as the destination for navigation. In the case where it is set in the device 3, it is determined whether or not the vehicle has parked in the parking lot corresponding to the complex facility (S8), and it is determined that the vehicle has parked in the parking lot corresponding to the complex facility. , the information about the destination set in the navigation device 3 is handed over to the mobile terminal 4 (S9, S11). Since the guidance for movement to the point set in the ground is provided (S13), it is possible to continue guidance for movement to the destination even after getting off the vehicle. As a result, it is possible to make the user reach the destination without fail even when the user needs to walk around the facility after getting off the vehicle.
Further, when a complex facility is set in the navigation device 3 as a destination, information on the destination set in the navigation device 3 is provided on condition that the vehicle approaches the complex facility within a predetermined distance. Since the guidance is ended without handing over to the mobile terminal 4 (S10), it is possible for the user who wishes to move to the complex facility to end the movement guidance upon arrival at the complex facility.
Also, in the portable terminal 4 that inherited the information about the destination, the recommended route to move from the position where the vehicle was parked to the point set as the destination via the entrance of the complex facility is obtained. (S12), and since guidance is provided based on the recommended route (S13), a recommended route that reduces the burden on the user from the parking position to the destination after the user parks the vehicle is searched for. Based on the searched recommended route, the user can surely reach the destination.
After the user enters the complex facility, the floor map of the complex facility is used to guide the recommended route from the entrance where the user entered to the point set as the destination (S13). Even when a complicated walking is required, the floor map can be used to ensure that the user reaches the destination.
In addition, there is a commercial complex as an example of a complex facility, and the point that can be set as the destination is a tenant in the commercial complex, so even if one tenant in the commercial complex is set as the destination, It is possible to make the user reach the destination without fail.

It should be noted that the present invention is not limited to the above-described embodiments, and of course various improvements and modifications are possible without departing from the gist of the present invention.
For example, in the present embodiment, the destination information is handed over from the navigation device 3 to the portable terminal 4 at the timing when the vehicle completes parking (S9, S11). It may be before For example, it may be the timing at which it is determined in S4 that the vehicle has arrived within a predetermined distance from the end point of the guidance route (that is, the timing at which movement guidance based on the guidance route ends), or the timing at which the vehicle enters the parking lot. It may be at the timing when the vehicle starts parking. Further, when the destination information is handed over before the vehicle completes parking, there may be a period during which the movement guidance by the navigation device 3 and the movement guidance by the portable terminal 4 overlap.
