  The information storage unit 80 is for storing information received by the communication unit 50, and is configured by the same HDD as the map data storage unit 30. Of course, other media such as a memory card may be used.

  The GPS receiving terminal 95 as a receiving device is embodied as a mobile phone with a GPS function in this embodiment. When the user is not on the vehicle 2, the GPS receiving terminal 95 is taken out of the vehicle 2 and moves with the user. The GPS receiving terminal 95 can acquire radio waves from satellites and can identify the current position based on the acquired radio waves. The GPS receiving terminal 95 stores history information in which the reception status of radio waves from satellites and position information are associated with time information. Here, the reception situation in this embodiment will be briefly described. In order to specify the current position by GPS, it is necessary to receive radio waves from at least three satellites. In this embodiment, regardless of whether or not the current position can be specified, the signal from at least one satellite is received. When radio waves are received, radio waves from satellites are assumed to have been received. Also, if no radio wave is received from any satellite, it is assumed that no radio wave is received from the satellite.

By the way, in this embodiment, it has the characteristics in the point which can guide the parking lot which considered the movement to the destination. The indoor movement determination process will be described based on the flowchart shown in FIG.
In the first step S101 (hereinafter, “step” is omitted and simply indicated by the symbol “S”), a destination is set. The destination is set by inputting a condition via the operation switch group 40, and a list of destination candidates that meet the condition is displayed on the display 61. Then, a destination is set by performing a selection operation from the list. In this embodiment, it is assumed that a facility (hereinafter referred to as “destination facility”) is set as the destination.

  In S102, it is determined whether or not the vehicle is parked in the parking lot corresponding to the destination facility set in S101 (hereinafter referred to as “destination parking lot”). In the present embodiment, the destination parking lot is an attached parking lot and a partner parking lot of the destination facility. However, the destination parking lot is not limited to the attached parking lot and the partner parking lot, for example, from the destination facility. A parking lot within a predetermined range (for example, within a radius of 500 m centering on the destination facility) may be used. In S102, it is determined that the vehicle 2 is parked at the destination parking lot when the ignition of the vehicle 2 is turned off within the area of the destination parking lot. When it is determined that the vehicle is not parked at the destination parking lot (S102: NO), S102 is repeated. When it is determined that the vehicle is parked at the destination parking lot (S102: YES), the process proceeds to S103. At this time, the time when it is determined that the vehicle is parked at the destination parking lot is stored as the parking period start time.

  In S103, it is determined whether or not the ignition of the vehicle 2 is turned on. When it is determined that the ignition of the vehicle 2 is not turned on (S103: NO), S103 is repeated. When it is determined that the ignition of the vehicle 2 is turned on (S103: YES), the process proceeds to S104. At this time, the time when it is determined that the ignition is turned on is stored and used as the end time of the parking period.

  In S104, the parking period in which the vehicle 2 is parked in the destination parking lot is specified based on the start time stored in S102 and the end time stored in S103. In the present embodiment, a period from when the ignition of the vehicle 2 is turned off to when it is turned on in the area of the destination parking lot is defined as a parking period. In addition, when the specified parking period is less than predetermined time (for example, 5 minutes), since the possibility that the user got off the vehicle 2 and went to the destination facility is low, it is excluded from the target of this processing. Note that the predetermined time for defining the exclusion target may be variable according to the type (genre) of the destination facility, the distance to the destination facility, and the like.

In S105, the history information of the GPS receiving terminal 95 including the specified parking period is acquired.
In S106, based on the reception status of the history information of the GPS receiving terminal 95 during the parking period acquired in S105, it is determined whether or not radio waves from the satellite were not received during the parking period. If it is determined that no radio waves have been received from the satellite during the parking period (S106: YES), the process proceeds to S110. When it is determined that radio waves from the satellite have been received at least during a part of the parking period (S106: NO), the process proceeds to S107.

  In S107, it is determined whether or not there is a period during which radio waves from the satellite are not received. When it is determined that there is no period during which no radio waves are received from the satellite (S107: NO), the process proceeds to S111. If it is determined that there is a period in which radio waves from the satellite are not received (S107: YES), the process proceeds to S108.

  In S108, it is determined whether or not radio waves from the satellite were received at the start time of the parking period. When it is determined that the radio wave from the satellite was received at the start time of the parking period (S108: NO), the process proceeds to S111. When it is determined that the radio wave from the satellite has not been received at the start time of the parking period (S108: YES), the process proceeds to S109.

  In S109, after parking is started, it is determined whether or not the point that received the radio wave from the satellite is within the area of the destination facility. When it is determined that the point where the radio wave from the satellite is received is within the area of the destination facility (S109: YES), the process proceeds to S110. When it is determined that the point where the radio wave from the satellite is received is not within the area of the destination facility (S109: NO), the process proceeds to S111.

  If no radio wave was received from the satellite during the parking period (S106: YES), or no radio wave was received from the satellite at the start of parking (S108: YES). When the point where the radio wave is received is in the area of the destination facility (S109: YES), in S110, the parking lot that can be moved indoors to the destination facility (hereinafter referred to as the parking lot) “Indoor mobile parking lot”). The indoor mobile parking lot in the present embodiment means that a passage connecting the destination parking lot and the destination facility is indoor, and it does not matter whether the destination facility itself is indoor.

  When there is no period during which no radio waves have been received from the satellite (S107: NO), when it is determined that radio waves have been received from the satellite at the start time of the parking period (S108: NO), or parking When it is determined that the point where the radio wave from the satellite is received is not within the area of the destination facility after the start of (S109: NO), in S111, the destination parking lot is passed indoors to the destination facility. Specify that it is not a movable indoor mobile parking lot.

  In S112, information indicating that the indoor moving parking lot is specified in S110 is stored. Specifically, for the destination parking lot identified as the indoor movement parking lot in S110, an indoor movement flag indicating that the parking lot can be moved indoors to the destination facility is associated with the destination facility. Store. At that time, it is stored as parking lot attribute information included in the POI information stored in the map data storage unit 30. The stored parking lot attribute information may be transmitted to the information center 90 via a communication network. In the information center 90, the received parking lot attribute information may be accumulated and transmitted to another navigation device, or may be used for creating map data. In the present embodiment, the indoor movement flag corresponds to “information indicating that the parking lot can be moved indoors to the destination”.

Details of the parking lot attribute information will be described with reference to FIG.
FIG. 3 is an example when the facility A has a plurality of partner parking lots. In this example, it is assumed that the parking lot P, the parking lot Q, and the parking lot R are associated in advance as partner parking lots for the facility A. Here, when it is specified that the parking lot P is an indoor moving parking lot that can move indoors to the facility A, as shown in FIG. 3, the indoor movement to the parking lot P associated with the facility A is performed. Set the flag.

FIG. 4 is a flowchart for explaining parking lot guidance processing. This process is performed at predetermined intervals (for example, every 100 msec) after the ignition is turned on.
In S121, it is determined whether or not a destination has been set. The destination setting is performed in the same manner as in S101. When it is determined that the destination is not set (S121: NO), the processing after S122 is not performed. When it is determined that the destination has been set (S121: YES), the process proceeds to S122. The destination set here corresponds to the “new destination”.

In S122, a parking lot corresponding to the destination set in S121 is searched.
In S123, it is determined whether there is a parking lot in which the indoor movement flag is set in the searched parking lot. When there is a parking lot where the indoor movement flag is set (S123: YES). The process proceeds to S125. When there is no parking lot where the indoor movement flag is set (S123: NO), the process proceeds to S124.

  In S124, normal parking lot guidance is performed and the parking lot guidance process is terminated. In the present embodiment, the parking lots corresponding to the destinations searched in S122 are displayed in a list in order of the distance from the destination.

  In S125, where there is a parking lot where the indoor movement flag is set (S123: YES), guidance based on the indoor movement flag is performed, and the parking lot guidance process is terminated. In the present embodiment, the parking lots corresponding to the destination searched in S122 are displayed in a list in order of the distance from the destination, and the parking lot for which the indoor movement flag is set is an indoor moving parking lot. The icon which shows that is displayed.

Here, a specific example of guidance based on the indoor movement flag will be described with reference to FIG.
In this example, it is assumed that the facility A is set as the destination (S121: YES), and the parking lots P, Q, R, S, T are searched as the partner parking lot of the facility A (S122). It is assumed that the indoor movement flag is set in the parking lots P and R among the searched parking lots (S123: YES), and guidance based on the indoor movement flag is performed (S125). In this case, since the indoor movement flags are set in the parking lots P and R, the parking lots P, Q, R, S, and T are listed in order from the shortest distance from the destination as shown in the screen image of FIG. In addition to the display, an icon indicating that the parking lots P and R are indoor moving parking lots is displayed.

  Guidance based on the indoor movement flag is not limited to displaying an icon indicating that it is an indoor movement parking lot, and can be performed by various methods. For example, when displaying a list of parking lots corresponding to the destination, raise the priority of the parking lots with the indoor movement flag set, or display only the parking lots with the indoor movement flag set in order of distance. List display. Further, for example, on the map displayed on the display 61, the indoor moving parking lot display is changed in color from the parking display that is not an indoor moving parking lot, the indoor moving parking lot display is blinked, or the frame is enclosed. It may be displayed in a relaxed manner.

  Moreover, you may change the guidance method of the parking lot corresponding to the destination based on weather information. For example, when it is determined that it is raining, guidance based on the indoor movement flag is performed, and when it is determined that it is not raining, guidance based on the indoor movement flag is performed. In addition to the presence or absence of rainfall or snowfall, for example, when the outside air temperature is not within a predetermined range (for example, 10 ° C. to 25 ° C.), the priority of the indoor mobile parking lot may be increased. Further, the guidance method may be changed based on various warnings such as strong winds, warnings, ultraviolet information, photochemical smog information, and the like.

  As described above in detail, in the navigation device 1 of the present embodiment, the parking period in which the vehicle 2 is parked at the destination parking lot corresponding to the set destination is specified (S104) and moved together with the user. The reception state of the radio wave from the satellite in the GPS receiving terminal 95 is acquired (S105). Then, based on the reception state in the parking period, it is determined whether or not the movement between the destination parking lot and the destination is movement through the indoor. When it is determined that the movement between the parking lot and the destination is an indoor movement (S106: YES, S109: YES), the destination parking lot is identified as an indoor moving parking lot (S110), An indoor movement flag is set (S112). Thereby, the information regarding the convenience of a parking lot like the information which shows that it is a parking lot which can move indoors to a destination can be created. And based on the created information, for example, it is possible to guide the parking lot considering the travel to the destination such as the guidance of the indoor moving parking lot, create map data considering the convenience of the parking lot, etc. As a result, user convenience is improved.

  When a new destination is set, a parking lot corresponding to the new destination is searched (S122). If there is a parking lot in which the indoor movement flag is set in the searched parking lot (S123: YES), guidance based on the indoor movement flag is performed (S125). In this embodiment, since the icon which shows that it is an indoor movement parking lot is displayed and guided to the parking lot which can move indoors to a destination, a user's convenience improves.

  Note that the control unit 10 of the present embodiment includes the “parking period specifying unit”, “reception state acquisition unit”, “indoor movement determination unit”, “information providing unit”, “corresponding parking lot search unit”, and “guidance unit”. Configure. 2 corresponds to processing as a function of “parking period specifying means”, S105 corresponds to processing as a function of “reception state acquisition means”, and S106 to S109 are “indoor movement determination means”. S112 corresponds to the processing as the function of the “information providing means”. Further, S122 in FIG. 4 corresponds to processing as a function of “corresponding parking lot search means”, and S125 corresponds to processing as a function of “guidance means”.

As mentioned above, this invention is not limited to the said embodiment at all, In the range which does not deviate from the meaning of invention, it can implement with a various form.
(A) Cancellation determination process If the indoor movement flag corresponding to the current destination has already been set for the parking lot that is not an indoor movement parking lot, is the indoor movement flag canceled according to the weather? It may be configured to determine whether or not. Specifically, the cancellation determination process shown in FIG. 6 may be performed after S111 in FIG.

Here, the cancellation determination process will be described based on the flowchart shown in FIG.
In S131, it is determined whether the indoor movement flag is set. When the indoor movement flag is not set (S131: NO), the processing after S132 is not performed. When the indoor movement flag is set (S131: YES), the process proceeds to S132.

In S132, weather information around the destination in the parking period is acquired.
In S133, based on the weather information acquired in S132, it is determined whether or not the weather during the period in which the GPS receiving terminal 95 can receive radio waves from the satellite was rainy. Specifically, when the GPS reception terminal 95 can receive radio waves from the satellite during the rainy weather (S133: YES), the process proceeds to S135. If the weather during the period in which the GPS receiving terminal 95 can receive radio waves from the satellite is not rainy (S133: NO), the process proceeds to S134.

In S134, since it was not raining, it is determined that the user is likely to have moved outdoors, and the indoor movement flag of the parking lot is maintained.
In S135, when the weather during the period when the radio wave from the satellite can be received by the GPS receiving terminal 95 is rainy (S133: YES), the indoor movement flag of the parking lot is canceled. The processing here is that if the user moves outdoors even though it is raining, it is an error that the indoor movement flag is set, and actually from the parking lot to the destination. Judge that there is a high possibility that it was not possible to move indoors.

  According to such a configuration, if the indoor movement flag is set in the parking lot that is not the indoor movement parking lot (S131: YES), whether or not to cancel the indoor movement flag depends on the weather. Judgment is made (S133). That is, if the weather around the destination is not rain (S133: NO), the indoor movement flag is maintained (S134), and if it is rain (S133: YES), the indoor movement flag is canceled (S135). Thereby, it can be determined appropriately according to the weather whether or not the indoor movement flag is canceled, and the accuracy of the indoor movement flag can be improved.

  Note that the control unit 10 constitutes a “cancel determination unit”, and S133 to S135 in FIG. 5 correspond to processing as a function of the “cancel determination unit”. In this example, whether or not to maintain the indoor movement flag is determined based on whether or not the weather around the destination is rainy. However, not only rain but also snow, hail, strong wind, etc. You may judge based on whether the weather was bad weather. Moreover, you may judge based on precipitation.

(A) Facility area When it is determined that the point where the radio wave from the satellite is received again is within the area of the destination facility after the period during which reception is not possible (S109: YES), the parking lot is identified as an indoor mobile parking lot did. By the way, for example, there is a passage that can be moved indoors from a destination parking lot, and the exit of the passage may be on a road adjacent to the destination, for example, a sidewalk. In this case, it is generally possible to move indoors from the parking lot to the destination, so it is desirable to guide it as an indoor moving parking lot. In view of this, the region including the road adjacent to the destination facility may be set as an enlarged destination facility region, and the determination process in S109 may be performed. For specifying the area of the enlarged destination facility, if the area of the road adjacent to the destination facility is stored in the map data, the area of the road adjacent to the destination facility is determined as the area of the destination facility. The area added to the area may be the “area of the enlarged destination facility”, or if the area of the road adjacent to the destination facility is not stored in the map data, a predetermined distance from the area of the destination facility ( For example, an area expanded by 15 m) may be set as an “area of an enlarged destination facility”.

Similarly, a road adjacent to a parking lot may have a passage entrance that can move indoors to a destination facility. Therefore, the area including the road adjacent to the parking lot may be an enlarged parking lot area, and the determination process in S108 may be performed. In addition, for the identification of the area of the enlarged parking lot, when the area of the road adjacent to the parking lot is stored in the map data, the area adjacent to the parking lot is added to the facility of the parking lot, It is good also as "the area of an enlarged parking lot", and when the area of the road adjacent to a parking lot is not memorize | stored in map data, the area expanded by predetermined distance (for example, 30m) from the area of a parking lot, It may be an “enlarged parking area”.
Further, the determination process in S108 may determine whether or not radio waves from the satellite were not received after a predetermined time (for example, 5 minutes) from the start time of the parking period.

(C) Parking lot attribute information In the said embodiment, although the partner parking lot was matched and memorize | stored with respect to a facility, you may comprise so that a facility may be matched and memorize | stored with respect to a parking lot. For example, when the parking lot Q is a partner parking lot of a plurality of facilities, the facility A, the facility B, and the facility C are associated with the parking lot Q in advance. Here, when it is specified that the vehicle can move from the parking lot Q to the facility A through the indoor space, the indoor movement flag may be set in association with the facility A for the parking lot Q.

(D) GPS receiving terminal In the said embodiment, the GPS receiving terminal was a mobile telephone. The GPS receiving terminal is not limited to a mobile phone, and may be any device as long as it can receive radio waves from a satellite and identify the current position. In particular, when the navigation device 1 is portable and moves with the user, the navigation device 1 itself may constitute the GPS receiving terminal 95.
