<1-6. Route Display System Processing>
Next, processing of the route display system 100 will be described. 6 to 12 are diagrams for explaining processing of the route display system 100. FIG.

  The route display system 100 of the present embodiment mainly executes a movement route storage process and a movement route display process. For this reason, first, an outline of the flow of the storage processing of the movement route will be described along the operation sequence of the entire system. FIG. 6 is a diagram illustrating a process sequence of the route display system 100 in the process of storing the movement route. As illustrated in FIG. 6, when the user activates the route display application 24 b of the mobile terminal 20, the mobile terminal 20 enters a standby state for the movement route storage process.

  Thereafter, when the ignition of the vehicle 10 is turned off, vehicle position information, destination information, and the like are transmitted from the vehicle 10 to the center 40. That is, when the ignition is turned off, the vehicle 10 acquires vehicle position information at that time and transmits it to the center 40. In addition, when the destination is set by the navigation device 14 when the ignition is turned off, the vehicle 10 also transmits destination information such as destination position information and estimated arrival time to the center 40. To do.

  When the center 40 receives information such as vehicle position information from the vehicle 10, the center 40 stores the information in the storage unit 43. Then, a request signal for starting to store the movement route is transmitted to the mobile terminal 20. The center 40 can grasp that the ignition of the vehicle 10 is turned off (that is, the vehicle is parked) by receiving information such as vehicle position information from the vehicle 10. That is, since it can be determined that the user subsequently gets off the vehicle 10 and moves, the center 40 requests the mobile terminal 20 to start storing the moving route.

  When the mobile terminal 20 receives a request signal for starting the storage of the travel route from the center 40, the mobile terminal 20 executes a travel route storage process. Thereby, the movement route of the user is stored in the mobile terminal 20.

  Here, the storage process of the movement route by the portable terminal 20 will be described in detail. FIG. 7 is a flowchart showing the movement path storing process.

  First, the storage process of the movement route by the portable terminal 20 starts when the route display application 24b is activated. When the route display application 24b is activated, the mobile terminal 20 determines whether or not a movement route storage start request has been acquired from the center 40 (step S701). This is performed by determining whether or not the mobile terminal 20 has received a request signal from the center 40 to start storing the travel route. If the movement path storage start request has not been acquired (No in step S701), the mobile terminal 20 monitors whether the request has been acquired again.

  On the other hand, when the movement path storage start request is acquired (Yes in step S701), the mobile terminal 20 starts the storage process of the movement path and acquires mobile position information (step S702). That is, when the movement route storage start request is acquired, the position information acquisition unit 22 acquires the position information of the mobile terminal 20. Next, the mobile terminal 20 determines whether or not it has moved a predetermined distance (step S703). The mobile terminal 20 periodically acquires mobile location information, and stores the mobile location information acquired at that time when the mobile terminal 20 moves a predetermined distance from the previously stored location. For this reason, when acquiring the mobile position information, the mobile terminal 20 determines whether or not the mobile terminal 20 has moved a predetermined distance compared to the previously stored mobile position information. The predetermined distance in this case can be set to 1 m, for example. However, it is not limited to 1 m and can be set arbitrarily.

  And the portable terminal 20 memorize | stores the acquired portable position information 24c in the memory | storage part 24, when it moved predetermined distance (it is Yes at step S703) (step S704). Note that in the case of the mobile position information acquired first after the movement route storing process is started, the mobile terminal 20 stores the information regardless of the distance from the previous position. On the other hand, if the mobile terminal 20 has not moved the predetermined distance (No in step S703), the mobile terminal 20 proceeds to the next process without storing the mobile location information in the storage unit 24.

  Next, the mobile terminal 20 determines whether or not there is a location registration instruction from the user (step S705). In the present embodiment, when there is a point of concern during movement after the user gets off, or when there is a point to stop by on the way home, the point can be registered. . For this reason, the mobile terminal 20 determines whether or not there is a location registration instruction from the user. If there is a registration instruction (Yes in step S705), the location information and facility information of the location is registered as the registration location information 24g. Is registered in the storage unit 24 (step S706). On the other hand, if there is no point registration instruction from the user (No in step S705), the point registration process is not performed and the process proceeds to the next process.

  Next, the mobile terminal 20 determines whether or not a predetermined distance has been reached from the start (step S707). After the mobile terminal 20 starts storing the travel route by acquiring the travel route storage start request, the mobile terminal 20 continues to acquire the mobile location information until the travel distance from the start reaches a predetermined distance. That is, the mobile terminal 20 ends the storage of the movement route when the movement distance after the movement route storage starts reaches a predetermined distance. For this reason, when acquiring the mobile position information, the mobile terminal 20 determines whether or not the moving distance from the start has reached a predetermined distance. Note that the predetermined distance in this case can be set as appropriate. For example, the predetermined distance may be set in advance, such as 100 m or 500 m, or the user may set the distance according to the size of the parking lot.

  If the movement distance from the start has not reached the predetermined distance (No in step S707), the mobile terminal 20 executes the process after the process (step S702) after acquiring the mobile position information again. On the other hand, when the predetermined distance has been reached (Yes in step S707), the mobile terminal 20 derives and stores the movement route (step S708).

  Specifically, the route deriving unit 21a reads the mobile location information 24c stored in the storage unit 24, and derives the movement route by continuously connecting the plurality of mobile location information 24c in time series. . Then, the route deriving unit 21a stores the derived travel route information as travel route information 24h in the storage unit 24, and ends the travel route storing process.

  As described above, the mobile terminal 20 periodically acquires the mobile location information, and stores the mobile location information acquired when the mobile terminal 20 moves a predetermined distance (first distance) from the previously stored location. And the portable terminal 20 continues the memory | storage process of this portable position information until the movement distance after starting the memory | storage of portable position information reaches | attains the predetermined distance (2nd distance). And when the movement distance after starting reaches the predetermined distance, the portable terminal 20 derives | stores and memorize | stores a movement path | route using portable position information.

  Next, the movement route display process will be described. The display of the movement route is an operation mainly performed when a user at a position away from the vehicle returns to the vehicle. FIG. 8 is a diagram illustrating a process sequence of the route display system 100 in the process of displaying the movement route.

  As illustrated in FIG. 8, when the user activates the route display application 24 b of the mobile terminal 20, the mobile terminal 20 enters a standby state for the movement route display process. Thereafter, the mobile terminal 20 requests the center 40 to transmit vehicle information and surrounding information. The vehicle information in this case is, for example, vehicle position information or destination information, and the peripheral information is store / facility information regarding stores and facilities existing around the vehicle 10.

  When the center 40 receives the transmission request signal of the vehicle information and the surrounding information, the center 40 requests the external database server 30 to transmit the surrounding information. Since the center 40 has acquired vehicle information when the ignition of the vehicle 10 is turned off, the center 40 requests the external database server 30 to transmit only peripheral information. The center 40 also transmits vehicle position information when transmitting a transmission request signal for surrounding information to the external database server 30.

  When the external database server 30 receives the peripheral information transmission request signal from the center 40, the external database server 30 falls within a predetermined range from the store / facility information 33b stored in the storage unit 33 based on the position based on the vehicle position information received at the same time. The store / facility information 33b related to the stores and facilities existing in is searched. Then, the external database server 30 transmits the searched store / facility information 33b to the center 40 as peripheral information.

  Next, the center 40 transmits vehicle information and surrounding information to the mobile terminal 20. When the mobile terminal 20 acquires the vehicle information and the surrounding information, the mobile terminal 20 causes the user to select a movement route to be displayed. In addition to the travel route stored in the current travel route storage process, if there is a travel route that was used in the past when the vehicle was parked at the same location, this is presented to the user and selected. It is processing. When the user selects one of the displayed travel routes, the mobile terminal 20 displays the selected travel route.

  Thereafter, when it is determined that the user has approached the vehicle 10, the portable terminal 20 requests the center 40 to start the engine 12 of the vehicle 10. When the center 40 obtains the engine start request from the portable terminal 20, the center 40 requests the vehicle 10 to start the engine 12, and the vehicle 10 starts the engine. And the display process of a movement route is complete | finished when a user arrives at the vehicle 10 and complete | finishes the route display application 24b.

  Here, the display process of the movement route by the portable terminal 20 will be described in detail. FIG. 9 is a flowchart showing the movement path display process.

  First, the display process of the movement route by the portable terminal 20 starts when the user activates the route display application 24b and instructs the display of the movement route. When the mobile terminal 20 starts the display process of the travel route, the mobile terminal 20 requests the center 40 to transmit vehicle information and surrounding information (step S901). This is performed when the mobile terminal 20 transmits a transmission request signal for vehicle information and surrounding information to the center 40.

  And the portable terminal 20 acquires vehicle information and periphery information from the center 40 (step S902). The vehicle information in this case is vehicle position information and destination information acquired by the center 40 from the vehicle 10 when the vehicle 10 is parked. The peripheral information is store / facility information around the vehicle 10 acquired by the center 40 from the external database server 30.

  And the portable terminal 20 displays the selection screen of the movement route to display (step S903). In addition to the current travel route, the mobile terminal 20 also stores past travel route information, and together with the current travel route information 24h, based on position information that seems to be the same parking lot as the current parking lot. The stored past movement route information 24h is read from the storage unit 24. Then, the portable terminal 20 displays the current travel path and the past travel path on the display unit 25. In addition, when the information of the past movement path | route is not memorize | stored, only the movement path | route memorize | stored this time will be displayed.

  The mobile terminal 20 determines whether or not the user has selected one of the displayed travel routes (step S904). If not selected (No in step S904), the presence / absence of selection is monitored again. On the other hand, if it is selected (Yes in step S904), the mobile terminal 20 displays the selected movement route on the display unit 25 (step S905).

  Here, the display of the movement route on the display unit 25 will be described in detail. The mobile terminal 20 displays a superimposed image in which the selected movement route is superimposed on the camera image or the map image. For this reason, first, a process for displaying a superimposed image in which a movement route is superimposed on a camera image will be described. When the moving path is superimposed on the camera image, the mobile terminal 20 activates the photographing unit 27 (camera) and acquires the camera image. Then, the mobile terminal 20 displays the selected movement route in an overlapping manner at a location corresponding to the display area of the acquired camera image.

  Specifically, the display control unit 21b acquires latitude information and longitude information from the position information of the position where the camera image is acquired. The display control unit 21b then determines each position (each pixel corresponding to the point captured as the camera image based on the latitude and longitude of the point where the camera image was captured, the direction where the camera image was captured, and the scale of the camera image. ) To derive the latitude and longitude. Then, the display control unit 21b associates the latitude and longitude of each position with the latitude information and longitude information of the movement path to be displayed, thereby generating a superimposed image in which the movement path is superimposed on the camera image.

  This movement route is drawn as a locus obtained by connecting a plurality of pieces of mobile position information as described above, and is displayed in a linear shape. In addition, the tip of the movement route is indicated by an arrow, and the direction of the arrow is determined according to the direction in which the user follows the route (for example, going and returning). The direction of this arrow can be changed automatically or manually.

  FIG. 10 is an example of a screen that displays a superimposed image of a camera image and a movement path. As described above, since the camera (photographing unit 27) is provided on the opposite side of the display unit 25, the user can make the display unit 25 in front (so that the display unit 25 can be visually recognized). Is held, a camera image of a landscape similar to the user's field of view is displayed on the display unit 25. The movement route is displayed superimposed on the camera image, and the route associated with the position is displayed superimposed on the actual landscape. Thereby, the user can grasp which place has moved in light of the actual scenery, and can reach the host vehicle by moving along the route.

  The mobile terminal 20 can also display a mark indicating the position of the vehicle 10 on the superimposed image. In the example of the screen shown in FIG. 10, a mark M1 indicating the position of the vehicle 10 is displayed at the position of the vehicle 10 in the camera image. The portable terminal 20 can display the mark M1 at a location corresponding to the position of the vehicle by associating the vehicle position information with the latitude and longitude information in the camera image. Thus, the user can grasp the position of the vehicle 10 by displaying the mark M1 indicating the position where the vehicle 10 is parked together with the movement route. Any mark M1 can be used as long as the position of the vehicle is known.

  Moreover, the portable terminal 20 can also display the spot registered when the user memorize | stored the movement path | route in a superimposed image. In the example of the screen shown in FIG. 10, when the user registers a location at the vending machine position when storing the travel route, a mark M2 indicating that the registered location is displayed at the corresponding location. Has been. Also in this case, the mobile terminal 20 can display the mark M2 at a location corresponding to the registered location by associating the location information of the registered location with the latitude and longitude information in the camera image. Thus, by displaying the mark M2 of the registration point together with the movement route, the user can grasp the position of the registration point. Thereby, when a user returns to a vehicle, since the position of a vending machine or a toilet can be grasped, for example, convenience is improved. As the mark M2, any mark can be used as long as it is known that it is a registered point.

  Moreover, the portable terminal 20 can also display the distance to the vehicle 10 on the display screen of the movement route. In the example of the screen shown in FIG. 10, the remaining distance to the vehicle is displayed at the top of the screen. The remaining distance to the vehicle increases or decreases as the user moves. This distance indicates the distance along the moving route to the vehicle, and the user can know the actual moving distance until the vehicle is reached. Note that a linear distance to the vehicle 10 may be displayed.

  Moreover, the portable terminal 20 can also display the estimated arrival time at the destination on the display screen of the travel route. In the example of the screen shown in FIG. 10, the estimated arrival time at the destination is displayed at the bottom of the screen. This is the time when the vehicle 10 is scheduled to arrive at the destination when the navigation device 14 sets the destination. The mobile terminal 20 acquires vehicle information from the center 40, but when the vehicle 10 has set a destination, the mobile terminal 20 also acquires an estimated arrival time at the destination in addition to the destination information. In addition, the mobile terminal 20 updates the estimated arrival time in consideration of the time elapsed when the user gets off the vehicle 10 and stops at another facility or the like. The user can always check the latest estimated arrival time at the destination even if he / she leaves the vehicle at an intermediate route, so he can decide the stay time at the facility considering the estimated arrival time. become.

  The mobile terminal 20 can also display store / facility information on the superimposed image. Although not shown in the example of the screen shown in FIG. 10, for example, when getting off the vehicle 10 and heading for the facility, the names of facilities around the vehicle 10, doorways, elevator locations, stairs locations, information centers Information such as location, handling products, congestion degree, etc. can be displayed. In this case, the mobile terminal 20 may display a mark indicating that there is store / facility information on the screen, and display each piece of information when the user touches the mark. Thereby, the user can move without hesitation to the target place when heading to the facility. Further, store / facility information may be displayed on the superimposed image when the user returns to the vehicle. For example, by displaying information on vending machines and toilets as facility information, the user can stop when returning to the vehicle, improving convenience. In addition, as long as it is understood that the mark in these cases is information on the facility, any mark can be used. In this case, it is preferable that the store / facility information existing around the vehicle 10 is acquired when the user gets off the vehicle 10.

  When displaying the store / facility information, the mobile terminal 20 may display the facility that the user has visited in the past and the facility that the user has never visited. In this case, the mobile terminal 20 may display using different landmarks, or display with different colors. Moreover, the past visit history may be displayed, or only the presence or absence of a visit may be displayed.

  In addition, a button for switching between a camera image and a map is displayed on the screen displaying the movement route. The user can switch between a superimposed image of the camera image and the movement route and a superimposed image of the map image and the movement route by selecting one of them.

  Therefore, a process for displaying a superimposed image in which a movement route is superimposed on a map image will be described. The display control unit 21b reads out the map information 24f and the movement route information 24h from the storage unit 24 and creates and displays a superimposed image by displaying the movement route so as to overlap the map. Specifically, the display control unit 21b acquires, from the storage unit 24, a predetermined range of map information 24f including the positions of the vehicle and the mobile terminal based on the vehicle position information and the mobile position information. In addition, the display control unit 21b acquires information 24h on the movement route selected by the user from the storage unit 24.

  Since the map information includes latitude information and longitude information of each point, the display control unit 21b associates the latitude information and longitude information of each point with the latitude information and longitude information of the moving route to be displayed. Then, a superimposed image in which the movement route is superimposed on the map image is generated. Then, the display control unit 21b displays the generated superimposed image on the display unit 25. Note that, similarly to the above, this movement route is a linear figure drawn as a locus connecting a plurality of pieces of mobile position information, and an arrow is displayed at the tip.

  FIG. 11 is an example of a screen that displays a superimposed image of a map image and a movement route. As shown in FIG. 11, the movement route is displayed superimposed on the map image. Similarly to the case where the superimposed image using the camera image of FIG. 10 is displayed, the mobile terminal 20 displays the moving route with an arrow, displays the distance to the vehicle 10, and displays the estimated arrival time at the destination. it's shown. In addition, the mobile terminal 20 displays the position of the vehicle 10 with the mark M1, and displays the registration point with the mark M2. Further, although not shown in FIG. 11, the mobile terminal 20 can also display store / facility information as in the case of a camera image.

  In the present embodiment, an example in which the mobile terminal 20 has map information has been described, but the present invention is not limited to this. For example, the mobile terminal 20 may have no map information, and the center 40 may have map information. In this case, the mobile terminal 20 requests the center 40 to transmit map information in a predetermined range including the positions of the vehicle 10 and the mobile terminal 20, generates a superimposed image based on the map information received from the center 40, Show it. When the portable terminal 20 requests map information from the center 40, a request signal including vehicle position information and current portable position information may be transmitted. The center 40 transmits map information of a predetermined range including a position corresponding to each position information to the mobile terminal 20.

  Returning to FIG. 9, the mobile terminal 20 determines whether or not the vehicle 10 has approached (step S906). The mobile terminal 20 moves with the movement of the user, and the position information acquisition unit 22 acquires its own position information even during the movement. And the portable terminal 20 judges whether it approached the vehicle 10 by comparing the acquired portable position information and vehicle position information. In addition, what is necessary is just to set arbitrary distances, such as 10m, 50m, 100m, suitably for the distance judged to be approaching, for example.

  If it is determined that the mobile terminal 20 is not approaching the vehicle 10 (No in step S906), the mobile terminal 20 performs a process of displaying a moving route and a process of determining an approach to the vehicle 10. On the other hand, when it is determined that the mobile terminal 20 has approached the vehicle 10 (Yes in step S906), the mobile terminal 20 requests the center 40 to start the engine 12 of the vehicle 10 (step S907).

  The case where the portable terminal 20 approaches the vehicle 10 indicates that the user has approached the vehicle 10, and indicates that the user will arrive at the vehicle 10 soon. For this reason, by starting the air conditioner by starting the engine 12 remotely in advance, when the user arrives at the vehicle 10, comfortable use such that the temperature in the passenger compartment is kept at an appropriate temperature becomes possible. The remote start process (step S907) of the engine 12 may be omitted. In this case, the process for determining the approach to the vehicle 10 (step S906) is also omitted.

  Then, when the user arrives at the vehicle 10 and ends the route display application 24b of the mobile terminal 20 (step S908), the moving route display process ends.

  In this way, the route that the user has moved down from the vehicle 10 is stored in the portable terminal 20 in advance, and is displayed when, for example, returning to the vehicle 10. It is possible to reliably return to the parking position. Furthermore, it is easier to grasp the route by superimposing and displaying the movement route on the camera image or the map image.

  The travel route information 24h stored in the storage unit 24 can be deleted by a user operation. Therefore, the movement route deletion process will be described. FIG. 12 is a flowchart showing the movement route deletion process.

  The movement route deletion process starts when the user activates the route display application 24b and instructs the deletion of the movement route. First, the mobile terminal 20 determines whether or not the travel route deletion button has been pressed (step S1201). Specifically, when the route display application 24b is activated, the mobile terminal 20 displays a delete button on a menu screen or the like, and monitors whether or not the button is pressed. In this determination process, the portable terminal 20 may periodically monitor whether or not the button is pressed, and may determine that when the button is pressed.

  If the delete button has not been pressed (No in step S1201), the process ends. On the other hand, when the delete button is pressed (Yes in step S1201), the mobile terminal 20 displays a list of travel routes (step S1202). Specifically, the mobile terminal 20 displays the travel route information 24h stored in the storage unit 24 as a list. The contents to be displayed can specify the moving route such as the time when the moving route is stored, the name of the facility where the vehicle 10 is parked when the moving route is stored, and the surrounding image acquired when the moving route is stored. Any list of information may be used.

  When the user selects any travel route from the list (step S1203), the mobile terminal 20 monitors whether or not a confirmation button for deleting the selected travel route has been pressed (step S1204). ). If the delete confirmation button has not been pressed (No in step S1204), the process ends without deleting the movement route. On the other hand, when the delete confirmation button is pressed (Yes in step S1204), the selected travel route information 24h is deleted from the storage unit 24 (step S1205). Thereby, the movement route is deleted by the user's operation.

<2. Second Embodiment>
Next, a second embodiment will be described. In the first embodiment, when the vehicle ignition is turned off, a request to start moving path storage is transmitted from the center to the mobile terminal, and the mobile terminal automatically starts the storage process of the moving path. A configuration may be adopted in which the user manually starts the storage process of the movement route. For this reason, in the second embodiment, a configuration for manually starting the storage process of the movement route will be described.

<2-1. System overview>
The route display system according to the second embodiment has the same configuration as the route display system 100 shown in FIG. The configurations of the vehicle 10, the mobile terminal 20, the external database server 30, and the center 40 according to the second embodiment are also the same as those in the first embodiment. In the second embodiment, the conditions for starting the movement route storage process in the portable terminal 20 are different from those in the first embodiment. Therefore, in the following, the movement route storing process will be described focusing on differences from the first embodiment.

<2-2. Travel route storage processing>
A travel route storing process according to the second embodiment will be described. FIG. 13 is a flowchart illustrating the movement path storing process according to the second embodiment.

  The storage process of the travel route by the mobile terminal 20 in the second embodiment also starts with the route display application activated. When the route display application is activated, the mobile terminal 20 determines whether or not the movement route storage start button has been pressed (step S1301). In the present embodiment, when the route display application is activated, the mobile terminal 20 displays a button for instructing the start of storage of the movement route on the display unit 25, and the movement route is obtained on the condition that the user presses the button. I am going to start memorizing.

  If the movement path storage start button has not been pressed (No in step S1301), the portable terminal 20 monitors whether or not the button has been pressed again. On the other hand, when the movement route storage start button is pressed (Yes in step S1301), the mobile terminal 20 starts the storage processing of the movement route and acquires the mobile location information (step S1302). This is the same processing as in step S702 described above. Thereafter, the same processing as in steps S703 to S708 described above is executed (steps S1303 to S1308). Thereby, the movement route can be stored as in the first embodiment.

  The mobile terminal 20 is configured to acquire the position information of the point where the route display application is activated and the position information of the point where the storage process of the movement route is started, and store each position information in the storage unit 24. It is good. Moreover, when displaying a movement path | route, it is good also as a structure which displays these each positional information so that identification is possible. Thereby, the user can grasp | ascertain the point which started the route display application, and the point which started the memory | storage process of a movement route. For example, when any point is a point where the host vehicle is parked, the user can grasp the position where the host vehicle is parked by looking at the display content. That is, even if the portable terminal 20 does not acquire the vehicle position information, it is possible to provide the same service as the vehicle position display.

<2-3. Other>
In the second embodiment, the user can start the storage process of the movement route at an arbitrary timing. For this reason, it becomes possible to memorize | store a movement path | route not only from a parking lot but from another place as a base point. That is, it is possible to store the movement route after getting off at the parking lot, and it is also possible to store the movement route based on an arbitrary point other than the parking lot. As an example of use at a place other than a parking lot, for example, there is a method of storing a movement route with a starting point as a base point when climbing and using it when descending.

<3. Modification>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made. Below, such a modification is demonstrated. All the embodiments including the embodiments described above and the embodiments described below can be appropriately combined.

  In each of the above-described embodiments, the configuration has been described in which the processing is terminated after the total travel distance from the start of the storage in the travel route storage processing reaches a predetermined distance, but the present invention is not limited to this. For example, the process may be automatically terminated after a predetermined time has elapsed after the movement path storing process is started. In this case, the mobile terminal 20 is configured to measure time after starting the storage process and end the storage process when a predetermined time has elapsed. For example, it is good also as a structure which a user finishes a process manually. In this case, since the storage process can be terminated at a desired point by the user, it is possible to store a movement route of an appropriate distance according to the place and the application.

  In each of the above-described embodiments, the configuration in which the camera image and the map image are switched and displayed has been described. In this case, for example, as illustrated in FIG. 14, a configuration in which a superimposed image of a camera image and a movement path, a map image, and a superimposed image of a movement path are displayed side by side can be given. Thereby, it is possible to check a superimposed image of both images without switching between the camera image and the map image. Moreover, it is good also as a structure which displays only the superimposed image of a camera image and a movement path | route, and it is good also as a structure which displays only the superimposed image of a map image and a movement path | route.

  Moreover, although each said embodiment demonstrated the structure which displayed the superimposed image of the detailed map image in a parking lot, and a moving path | route, it is not limited to this. For example, when displaying a movement route from a location outside the parking lot, a superimposed image of a wide-area map image and the movement route may be displayed. Specifically, as shown in FIG. 15, a superimposed image is generated in which a moving route from the current location to the parking lot is superimposed on a wide-area map image, and the superimposed image is displayed. In this case, when the user moves to approach the parking lot or enters the parking lot, it is preferable to switch to a superimposed image with a detailed map image in the parking lot as shown in FIG.

  Further, in the above-described embodiment, it has been described that various functions are realized in software by the arithmetic processing of the CPU according to the program. However, some of these functions are realized by an electrical hardware circuit. Also good. Conversely, some of the functions realized by the hardware circuit may be realized by software.
