As shown in FIG. 4D, since the bad weather recommendation POI 304 exists in the bad weather area 308, it is handled as the bad weather recommendation POI presented to the user.

  Next, the operation of the navigation device 100 in this example will be described with reference to the drawings. Note that detailed descriptions of processes not particularly related to the present invention may be omitted. In addition, the navigation apparatus 100 of this example is configured to start the navigation process when a recommended spot search instruction in bad weather is received from the user.

  FIG. 5 is a flowchart illustrating an example of navigation processing executed by the navigation device 100.

  In the navigation processing, first, the control unit 10 receives a selection operation for determining a search range for bad weather recommendation POI information from the user, and determines a search range according to the received selection operation (step S101). In addition, although the navigation apparatus 100 of this example is configured to determine the search range according to the selection operation from the user, the periphery of the current position of the user is determined as the search range without receiving the search range selection operation from the user. It is good also as a structure.

  When the search range is determined, the control unit 10 searches for a recommended bad weather POI within the determined search range (step S102). That is, the control unit 10 searches the bad weather recommendation POI with reference to the bad weather recommendation POI information storage unit 22. When the navigation device 100 allows the user to perform a search range selection operation, the navigation apparatus 100 presents a bad weather area including an area with bad weather and an area with bad weather in the future, and makes a selection for the presented bad weather area. The bad POI around the bad weather area selected by the user may be searched for. According to such a configuration, useful information can be provided to the user reflecting the user's intention. In addition, it is possible to efficiently search for a bad weather recommendation POI.

  When the bad weather recommendation POI is searched, the control unit 10 stores the searched bad weather recommendation POI as search result information in the search result information storage unit 23 (step S103).

  When the search result information is stored, the control unit 10 determines a bad weather recommendation POI for executing the presentation determination process (step S104). Specifically, the control unit 10 refers to the search result information and executes the presentation determination process for any of the recommended bad weather POIs that have not performed the presentation determination process (that is, the determination result has not been determined). Determined as bad weather recommended POI.

  When the bad weather recommendation POI for executing the presentation determination process is determined, the control unit 10 executes the presentation determination process for the determined bad weather recommendation POI (step S200).

  FIG. 6 is a flowchart illustrating an example of the presentation determination process.

  In the presentation determination process, first, the control unit 10 calculates the time required for arrival at the bad weather recommendation POI (step S201). In other words, the control unit 10 specifies the current position, and calculates the required time from the specified current position to arrival at the bad weather recommendation POI.

  When the required time until arrival at the bad weather recommendation POI is calculated, the control unit 10 identifies the bad weather area when the calculated required time has elapsed (step S202).

  When the bad weather area is specified, the control unit 10 determines whether or not the position of the searched bad weather recommended POI exists within the specified bad weather area (step S203). Note that the navigation device of this example is configured to identify bad weather areas using areas divided into a grid and determine whether there is a bad weather recommendation POI in the identified bad weather area. It is good also as a structure which determines whether the weather of the position of POI is bad weather.

  When it determines with not existing in a bad weather area (N of step S203), the control part 10 determines not to set it as bad weather recommendation POI shown to a user (step S204). Specifically, the control unit 10 updates the search result information with the determination result of the bad weather recommendation POI determined as not existing in the bad weather area as “0”.

  On the other hand, when it determines with existing in a bad weather area (Y of step S203), the control part 10 determines setting it as bad weather recommendation POI shown to a user (step S205). Specifically, the control unit 10 updates the search result information by setting the determination result of the bad weather recommendation POI determined to be present in the bad weather area as “1”.

  When the search result information is updated to “0” or “1” by the presentation determination process, the control unit 10 returns to the navigation process and determines whether there is a bad weather recommendation POI that has not been subjected to the presentation determination process ( Step S105). That is, the control unit 10 determines whether or not the presentation determination process is executed for all bad weather recommended POIs included in the search result information and the determination result is determined.

  When it is determined that there is a bad weather recommendation POI for which the presentation determination process has not been executed (Y in step S105), the control unit 10 proceeds to step S104 and determines bad weather POI information for which the presentation determination process is to be executed.

  On the other hand, when it is determined that there is no bad weather recommendation POI for which the presentation determination process has not been executed (N in Step S105), the control unit 10 can select a bad weather recommendation POI with a determination result of “1” for the user. (Step S106). That is, when the controller 10 arrives at the searched bad weather recommendation POI, it provides the user with the bad weather recommendation POI that is the bad weather area.

  When the bad weather recommendation POI with the determination result “1” is displayed to be selectable, the control unit 10 accepts a selection operation from the user, and selects the bad weather recommendation POI displayed by the received selection operation as a destination or a transit point. It is determined whether or not (step S107).

  When it is determined that the selection operation received is not a selection operation with the recommended bad weather POI displayed as the destination or waypoint (N in step S107), the control unit 10 ends the navigation process.

  On the other hand, when it is determined that the accepted selection operation is a selection operation with the displayed recommended bad weather POI as a destination or waypoint (Y in step S107), the control unit 10 selects the recommended bad weather POI selected by the user. Is set as the destination or waypoint (step S108).

  When the destination or waypoint is set, the control unit 10 searches for a route to the destination or waypoint and starts route guidance (step S109).

  When the route guidance is executed, the control unit 10 determines whether or not to terminate the route guidance (step S110). That is, the control unit 10 determines whether or not the destination or the waypoint has been reached. When it is determined that the route guidance is not finished (N in Step S110), the control unit 10 proceeds to Step S109 and determines whether or not the guidance route is finished again.

  On the other hand, when it determines with complete | finishing route guidance (Y of step S110), the control part 10 complete | finishes route guidance and complete | finishes a navigation process.
