  By the way, in some countries and regions, the entry of ordinary people (especially foreigners) is restricted by special rules that are not in general traffic rules such as social and political situations. (For example, military facilities). When a vehicle carrying a general person enters such a place, it may be arrested or taken by local police or military personnel. In such cases, you may be forced to pay a high fine to be released after being detained at the site for a long time and investigated.

  However, even if a conventional in-vehicle navigation device sets a place where the entry of ordinary people is restricted as a navigation destination, route guidance may be normally performed to that place. As a result, the user cannot avoid being violated by the rules unless he / she recognizes in advance that the entry to the place is restricted or notices in the field.

  Therefore, the present invention has been made in view of the above points, and it is necessary for the host vehicle to enter a destination that is restricted by special rules not defined in general traffic rules. It is an object of the present invention to provide an in-vehicle navigation device that can be avoided and, by extension, can avoid the economic burden and mental pain that are imposed on the user by violating the rules.

  Further, the entry restriction determination unit 29 compares the entry restriction region information read and acquired from the storage medium 12 with the waypoint set by the waypoint setting unit 25, so that the set waypoint is determined. It is determined whether or not it exists in the entry restriction area.

  Further, the entry restriction determination unit 29 compares the entry restriction area information read and acquired from the storage medium 12 with the own vehicle position calculated by the own vehicle position calculation unit 15, thereby determining the own vehicle position. It is determined whether or not it exists in the entry restriction area.

  Further, in the present embodiment, the navigation main unit 2 has an entry restriction notifying unit 30 as an entry restriction notifying unit. The entry restriction notifying unit 30 includes an entry restriction determining unit 29, a display processing unit 20, and Speakers 9 are connected to each other.

  When the entry restriction determination unit 29 determines that the set destination exists in the entry restriction area, the entry restriction notification unit 30 notifies the user that the destination is within the entry restriction area. Is notified by the image display on the display 8 and the sound output from the speaker 9. This notification may be, for example, an image display or voice output of a message such as “I am going to an area where general people are not allowed to enter”.

  In addition, when the access restriction determination unit 29 determines that the set via point exists in the access restriction area, the access restriction notifying unit 30 restricts the access point to the user. The notification of the presence in the area is made by displaying an image on the display 8 and outputting a sound from the speaker 9. This notification may be, for example, displaying an image or outputting a message with a content such as “I am going through an area where general people are not allowed to enter”.

  Furthermore, when the entry restriction determination unit 29 determines that the own vehicle position is in the entry restriction area, the entry restriction notification unit 30 determines that the own vehicle position is within the entry restriction area. The notification to the effect that it is present in the inside is made by displaying an image on the display 8 and outputting a sound from the speaker 9. This notification may be, for example, an image display or voice output of a message such as “Currently traveling in an area where general people are not allowed to enter”.

  Further, in the present embodiment, the navigation main unit 2 has an access restriction area outside guide unit 31 as outside entry restriction area guidance means, and the entry restriction area guidance unit 31 includes an entry restriction notification part 30. And a display processing unit 20 are connected to each other.

  When the notification indicating that the set destination exists within the restricted access area is made by the restricted access notification section 30, the access restriction outside guide section 31 will provide a new destination after the notification. Suggestions to users. In other words, the entry restriction area outside guide unit 31 has a new destination within a predetermined distance from the set destination outside the entry restriction area (for example, within a radius of 1 km centered on the set destination). A point belonging to the same type (for example, a type such as a parking lot or a resting place) as the set destination existing at the position is displayed on the display 8 as a state that the user can select by operating the input operation unit 5. It is like that. Alternatively, the guidance section 31 outside the restricted access area, as a proposal of a new destination, a point that exists near the entrance or exit of the restricted access area outside the restricted access area (for example, a position within 100 m from the entrance or the exit). The user may select a state that can be selected by the operation of the input operation unit 5 on the display 8. In this manner, the entry restriction area outside guide unit 31 performs guidance for prompting the user to go to a destination outside the entry restriction area. When the new destination proposed in this way is selected by the user, the new destination is set by the destination setting unit 23, and then the route calculation unit 24 and the guide image drawing unit 26 are set. The voice guidance unit 27 or the like shifts to route guidance along the recommended route to the new destination.

  In addition, when the notification that the set waypoint exists is within the access restriction area by the access restriction notification unit 30, the access control area outside the access restriction area 31 generates a new one after the notification. A waypoint is proposed to the user. In other words, the outside entry restricted area guide unit 31 exists as a new waypoint within a predetermined distance from the set place outside the entry restricted area (for example, within a radius of 1 km with the set place as the center). A point belonging to the same type (for example, a resting place) as the set waypoint to be displayed is displayed on the display 8 as a state that can be selected by the user by operating the input operation unit 5. Alternatively, the outside entry restricted area guide unit 31 allows the user to select a point existing near the entrance or exit of the entry restricted area outside the entry restricted area by operating the input operation part 5 as a new waypoint proposal. It may be displayed on the display 8 as a special state. In this way, the outside entry restricted area guide unit 31 performs guidance for prompting the user to go through a route point outside the entry restricted area. When the new waypoint proposed in this way is selected by the user, the route placement unit 24 and the guide image drawing unit 26 are set after the new waypoint is set by the waypoint setting unit 25. The voice guidance unit 27 and the like shift to route guidance along the recommended route via this new waypoint.

  Furthermore, if the entry restriction notifying unit 30 reports that the vehicle position is within the entry restriction area, the entry restriction outside guidance unit 31 goes out of the entry restriction area after the notice. Is displayed on the display 8 via the display processing unit 20. In this way, the outside entry restricted area guide unit 31 performs guidance for prompting the user to leave the restricted entry area. This guidance may be performed by voice output through the speaker 9. Further, during this guidance, the entry restriction area outside guide unit 31 can display a map of the relationship between the area range of the entry restriction area and the vehicle position in an easy-to-understand manner, or can leave the entry restriction area the earliest. It is preferable to display the route.

  Therefore, according to the present embodiment, even if a destination or waypoint that exists within the access restriction area is set, the destination or waypoint exists within the access restriction area by the access restriction notification unit 30. It is possible to alert the user by notifying the user of the fact and the guidance unit 31 outside the restricted access area suggests a new destination or waypoint to the user and prompts the user to go outside the restricted access area. As a result, it is possible to prevent the host vehicle from entering a destination and a transit point where entry is restricted by a special rule that is not defined in general traffic rules. In addition, the new destinations and waypoints proposed to the user by the guidance section 31 outside the restricted access area have a relevance such that the distance is close to the initial destination and waypoints or the type is the same Therefore, it is possible to propose new destinations and waypoints that reflect the user's original intention as much as possible, and to ensure user convenience.

  Furthermore, according to the present embodiment, even when the host vehicle is traveling in the entry restriction area, the entry restriction notification unit 30 notifies the user that the own vehicle position exists in the entry restriction area. It is possible to provide guidance that prompts the user to leave the restricted access area by the guide part 31 outside the restricted access area. As a result, it is possible to quickly eliminate the state in which the host vehicle has entered the area where entry is restricted by a special rule that is not defined in general traffic rules.

  In addition to the above configuration, in the present embodiment, the navigation main unit 2 further includes an action restriction determination unit 32 as action restriction determination means. The action restriction determination unit 32 includes a destination setting unit 23. The waypoint setting unit 25, the vehicle position calculation unit 15, the data read control unit 16, and the buffer 18 are connected to each other.

  The action restriction determination unit 32 sets the vehicle position when the destination is set by the destination setting unit 23, when the waypoint is set by the waypoint setting unit 25, or when the vehicle position calculation unit 15 sets the vehicle position. When calculated, the data reading control unit 16 is caused to output a reading request for reading the action restricted area information from the storage medium 12 to the data reading device 3. The action restriction area information read from the storage medium 12 by the data reading device 3 in accordance with this read request is acquired by the action restriction determination unit 32 via the buffer 18.

  Then, the action restriction determination unit 32 compares the action restriction region information read and acquired from the storage medium 12 with the destination set by the destination setting unit 23, so that the set destination is It is determined whether or not it exists in the action restriction area.

  In addition, when the set destination is the restricted access area, it is possible to determine whether or not such a destination exists in the action restricted area by specially allowing the user to enter the restricted entry area. Unless there is a special circumstance (for example, the user is a person related to a facility in the restricted access area), it is meaningless at all. This is because if the user cannot enter the restricted area, no action can be taken in the restricted area.

  Therefore, the determination by the action restriction determination unit 32 is performed only when the set destination exists outside the restricted access area or when there is a circumstance where the user can enter the restricted entry area. preferable. As for the presence / absence of circumstances in which the user can enter the restricted access area, for example, it is configured to allow the input operation unit 5 to input whether or not the user is a person related to the facility in the restricted access area, You may make it judge based on the input result.

  Further, the action restriction determination unit 32 compares the action restriction area information read and acquired from the storage medium 12 with the waypoint set by the waypoint setting unit 25, so that the set waypoint is determined. It is determined whether or not it exists in the action restriction area. Note that this determination about the waypoint is for the same reason as the above-described determination about the destination, when the set waypoint is outside the restricted access area, or where the user can enter the restricted access area. It is preferable to carry out only when there is a problem.

  Further, the action restriction determination unit 32 compares the action restriction region information read and acquired from the storage medium 12 with the own vehicle position calculated by the own vehicle position calculation unit 15, so that the own vehicle position is determined. It is determined whether or not it exists in the action restriction area. In addition, for the same reason as the determination for the destination described above, the determination regarding the own vehicle position may be performed when the calculated own vehicle position exists outside the entry restriction area or the user may enter the entry restriction area. It is preferable to perform it only when there is a circumstance that can be done.

  Further, in the present embodiment, the navigation main unit 2 includes a restriction content notification unit 34 as a restriction content notification unit. The restriction content notification unit 34 includes an action restriction determination unit 32, a display processing unit 20, and Speakers 9 are connected to each other.

  When the action restriction determination unit 32 determines that the set destination exists in the action restriction area, the restriction content notification unit 34 notifies the user of the action restriction content at the destination. This notification is performed by image display on the display 8 and audio output from the speaker 9. This notification may be, for example, an image display or audio output of a message that indicates “parking / stopping and photography are prohibited at the destination”.

  In addition, when the action restriction determination unit 32 determines that the set waypoint exists within the action restriction region, the restriction content notification unit 34 restricts the user to action restriction at the waypoint. Is notified by image display on the display 8 and sound output from the speaker 9. This notification may be, for example, an image display or audio output of a message that indicates that “parking and stopping and photography are prohibited at the waypoint”.

  Further, when the action restriction determination unit 32 determines that the own vehicle position is in the action restriction region, the restriction content notification unit 34 notifies the user of action restriction at the own vehicle position. The notification of the contents is performed by displaying an image on the display 8 and outputting a sound from the speaker 9. This notification may be, for example, an image display or voice output of a message such as “parking / stopping and photography are prohibited at the current location”.

  Therefore, according to the present embodiment, even if the set destination or waypoint or the calculated vehicle position exists in the action restriction area, the restriction content notification unit 34 causes the destination, waypoint or The user can be alerted by notifying the content of the action restriction at the vehicle position. Thereby, the user can avoid taking an action exceeding the limit defined by a special rule that is not included in the general traffic rules at the destination, the waypoint, or the own vehicle position.

  Next, the main operation of this embodiment will be described.

  In this embodiment, after starting the in-vehicle navigation device 1, first, as shown in step 1 (ST1), the destination setting by the destination setting unit 23, the setting of the waypoint by the waypoint setting unit 25, and By calculating the own vehicle position by the own vehicle position calculation unit 15, the destination, the waypoint, and the target point of the own vehicle position that are the targets of processing in the subsequent steps are determined.

  Next, in step 2 (ST2), the entry restriction determination unit 29 determines whether or not the target point determined in step 1 (ST1) exists in the entry restriction area, and exists in the entry restriction area. For target points to be processed, the process proceeds to step 3 (ST3), and for target points existing outside the entry restriction area, the process proceeds to step 7 (ST7).

  Here, the processes after Step 3 (ST3) will be described first. In Step 3 (ST3), the entry restriction notifying unit 30 notifies the user that the target point is in the entry restriction area. To go to step 4 (ST4).

  Next, in step 4 (ST4), the outside entry restricted area guide unit 31 guides the user outside the entry restricted area, and the process proceeds to step 5 (ST5). Specifically, when the target point is a destination, a new destination that exists outside the restricted access area is proposed, and guidance for urging to go outside the restricted access area is provided. In addition, when the target point is a stopover point, a new stopover point that exists outside the restricted access region is proposed to guide the user to go outside the restricted access region. Further, when the target point is the own vehicle position, guidance is provided to prompt the user to leave the restricted area.

  Next, in step 5 (ST5), the user is selected according to the guidance in step 4 (ST4) (for example, selection of a proposed new destination), and the process proceeds to step 6 (ST6).

  On the other hand, in step 7 (ST7), the action restriction determination unit 32 determines whether or not the target point exists in the action restriction area. If the target point exists in the action restriction area, step 8 (ST8). ), The process ends if it exists outside the action restriction area.

  Next, in step 8 (ST8), the content of action restriction in the action restriction area is notified by the restriction content notification unit 34, and the process proceeds to step 6 (ST6).

  Finally, in step 6 (ST6), an avoidance action (for example, route guidance to a destination outside the access restriction area) based on the user's selection in step 5 (ST5) is taken, By executing the action restriction conforming to the contents of the action restriction notified in step 8 (ST8), the special rules in the access restriction area and the action restriction area are observed.

  As described above, according to the present embodiment, it is possible to prevent the host vehicle from entering the restricted access area and taking prohibited actions in the restricted action area, and thus , It is possible to avoid the financial burden and mental pain imposed on the user by violating the rules.

  As a more preferred embodiment, when the access restriction area is an area where entry of foreigners is prohibited, it is provided with confirmation means for confirming whether or not the user is a foreigner based on an input operation of the user. To. Then, the entry restriction determination unit 29 determines whether the destination, waypoint, or own vehicle position exists within the entry restriction area only when the confirmation means confirms that the user is a foreigner. The determination operation to be performed is performed.

  By doing so, it is possible to prevent unnecessary notification from the entry restriction determination unit 29 and unnecessary guidance from the entry restriction region outside guidance unit 31 even to the citizens.

  In a more preferred embodiment, whether or not the user is an outsider when the action restriction area is an area in which the action of an outsider who is not related to a predetermined facility existing in the area is restricted. Confirmation means for confirming the above based on the input operation of the user is provided. Then, the action restriction determination unit 32 determines whether or not the destination, waypoint or own vehicle position exists in the action restriction area only when the confirmation means confirms that the user is an outsider. The determination operation for determining is performed.

  By doing so, it is possible to prevent unnecessary information from being sent by the restriction content notification unit 34 to the parties concerned.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible as needed.
