The acquired information is stored in the RAM 7.

  The bus line 10 is configured to be communicably connected to each part constituting the navigation device 1 of the present invention.

Next, the operation of the navigation device 1 of the present invention configured as described above will be described using a flowchart. FIG. 2 is a flowchart showing the operation of the navigation device. Note that the weather information is assumed to be acquired in advance when navigation is started.

  First, it is determined whether or not a destination is input from the user to the navigation device 1 (S1). If the destination is not input in S1 (S1, NO), the process waits until the destination is input. In addition, when the movement of the navigation device is confirmed without changing the destination (latitude / longitude change detected by the current position detection unit 2a), the flow process may be terminated. When the destination is input in S1 (S1, YES), the determination unit 2c determines whether or not the input destination includes the destination in the weather information acquired by the data communication unit 9 (S2). If it is determined in S2 that the destination is included in the weather information (S2, YES), the alternative destination search unit 2d searches for an alternative destination having the same classification as the destination not included in the weather information (S3). . In S3, the alternative destination searched by the alternative destination search unit 2d is displayed on the display unit 8 (see FIG. 3) (S4). Next, the determination unit 2c determines whether or not the user has selected from the alternative destination displayed on the display unit 8 via the input unit 4 (S5), and searches for a route to the alternative destination selected by the user. A search is performed by the unit 2b (S6). Then, the alternative destination searched in S6 is set as a new destination, and the route guidance unit 2e starts route guidance (S7).

  If it is determined in S2 that the destination is not included in the weather information (S2, NO), the route search unit 2b searches for the route to the destination that the user first input (S8) and is searched. The route guidance unit 2e starts guidance for the route to the destination.

  According to the navigation device of the present invention configured as described above, when the user sets the destination, it is determined whether the input destination is included in the weather information acquired from the outside, and the weather information is included in the weather information. When it is determined that the destination is included, an alternative destination not included in the weather information similar to the destination set by the user is searched and displayed (see FIG. 3), and the user selects the alternative destination. It is possible to guide the route to the alternative destination.

  As described above, the embodiment of the present invention has been described. However, the present invention is not limited to the above embodiment, and the same effect can be obtained even when various changes are made. For example, when the alternative destination is searched in S3, if the alternative destination is not found, the user may be notified that the weather / environment of the destination is unfavorable. Good.

(Second Embodiment)
Next, processing when an alternative facility is not found will be described using a flowchart. FIG. 4 is a flowchart showing the operation of the navigation device in another embodiment. Note that the weather information is assumed to be acquired in advance when navigation is started.

As shown in FIG. 4, the navigation apparatus according to another embodiment of the present invention first determines whether or not a destination is input from the user to the navigation apparatus 1 (S10. If it is not input (S10, NO), it waits until the destination is input, and the movement of the navigation device is confirmed (detected by the current position detection unit 2a) without setting the destination in the process of S10. If the destination is input in S10 (YES in S10), the input destination is displayed in the weather information. Whether or not the destination is included is determined by the determination unit 2c (S11) If it is determined that the destination is included in the weather information in S11 (S11, YES), the weather information The alternative destination search unit 2d searches for an alternative destination having the same classification as the destination not included in the destination (S12), and whether or not the alternative destination is found when the alternative destination is searched in S12 is controlled. 2 (S13), and if there is an alternative destination (S13, YES), the alternative destination is displayed on the display unit 8 (see FIG. 3) (S14) The alternative displayed on the display unit 8 in S14 The control unit 2 determines whether or not the user has selected from the destination (S15), and causes the route search unit 2b to search for a route to the alternative destination selected by the user in S15 (S16), and is searched in S16. The alternative destination is set as a new destination, and the route guidance unit 2e starts route guidance (S17).

  When it is determined that the destination is not included in the weather information in S11 (S11, NO), the route search unit 2b searches for the route to the destination that the user first input (S19). The route guidance unit 2e starts guidance for the route to the destination (S20). If no alternative destination is found in S13 (NO in S13), the user is notified that the weather / environment of the destination set by the user is bad using the display unit 8 or a speaker (not shown) (S18). ). When the user does not select an alternative destination in S15, or when the movement of the vehicle is confirmed (confirmed by a change in latitude / longitude detected by the current position detection unit 2a) (S15, NO), the process moves to S18. The destination set by the user is notified that the weather / environment is bad (S18). Thereafter, the route to the destination set by the user is searched (S19), and the route to the destination searched in S19 is searched. Guidance is started (S20).

  According to the navigation device of the present invention configured as described above, when the weather information is determined to be bad for the destination input by the user and the alternative destination is searched, the alternative destination is not found. However, since the user is notified that the weather / environment at the destination is bad, the user can grasp the weather / environment information of the destination when the destination is set. Even if the user starts moving without selecting an alternative destination after searching for an alternative destination, the route guidance to the destination set by the user first is started, and the weather at the arrival of the destination It is possible to notify the user that the state is bad.

  Moreover, although the navigation apparatus 1 of the present invention has been described using the first embodiment and the second embodiment, the present invention is not limited thereto, and similar effects can be obtained even if various modifications are made. Can do. For example, when the search is performed by the alternative destination search unit 2d, an alternative destination including at least one condition of the distance to the destination, the arrival time, and various expenses set by the user first is searched. The alternative destination close to the same condition as the destination initially set by the user can be searched. Moreover, the data communication part 9 can respond to the change of a weather condition by acquiring weather information from the information server which exists on an external network.

  In the present invention, when a user sets a destination, the weather information of the destination is confirmed, and when there is weather information such as bad weather or bad situation, an alternative destination similar to the destination is searched for the user. It is useful as a navigation device that can be notified.
