  By the way, a user of a navigation device mounted on a vehicle wants to know a traffic jam situation on the road when the vehicle actually travels and a method for avoiding the traffic jam situation in advance.

  However, in the conventional navigation device described above, although it is possible to perform scroll processing along the route from the presently set current location to the destination, the road condition changes during scroll processing of the set route that requires a relatively long time. However, the route scrolling process is not performed in consideration of the road conditions that change from moment to moment.

  The present invention has been made in view of such circumstances, and even when the set route is being scrolled, when traffic information such as traffic congestion is acquired, the traffic route is avoided along the detour route. The present invention provides a navigation device that can perform scroll processing.

  A navigation device according to the present invention includes a route setting means for setting a route to a destination where a vehicle should travel, and a scroll along the set route for displaying the set route on a display means and confirming the set route. A navigation device comprising setting route scroll means for performing processing and receiving means for acquiring traffic information of the setting route and roads around the setting route, wherein the setting route is displayed by the setting route scroll means. The detour route setting means for setting a detour route for detouring a part of the set route of the scroll traveling direction based on the traffic information acquired by the receiving means during the scroll processing displayed on the detour, and the detour route And a setting path changing means for changing the setting path by incorporating it into the setting path in the scrolling direction.

  With such a configuration, when the receiving unit acquires traffic information such as traffic jams in the set route in the scrolling direction while displaying the set route on the display unit and performing scroll processing, the traffic jam etc. In order to avoid this, a detour route that bypasses a part of the set route is set, and this detour route is incorporated into the set route and the set route is changed.

  In the navigation device according to the present invention, when the set route scroll means displays the set route on the display means and is scrolling and reaches the branch point to the detour route, And further comprising route selection inquiry means for inquiring the user whether or not to select the bypass route by temporarily stopping scroll processing, and the display means displays the route selected by the user in response to the inquiry by the route selection inquiry means. It can be configured to display on the screen and perform scroll processing.

  With such a configuration, when the set route is displayed on the display means and scrolling is in progress, and the branch point to the detour route is reached, the set route scroll processing is temporarily stopped and the detour route is stopped. The user is asked whether or not to select, and the route selected by the user is displayed on the display means and scrolled.

  In the navigation device according to the present invention, the traffic information is information on traffic congestion in a part of the set route in the scrolling direction displayed on the display unit by the set route scroll unit in the set route. Also good.

  With such a configuration, while the setting route is displayed on the display unit and scrolling, the receiving unit acquires that traffic congestion has occurred in a part of the setting route in the scrolling direction. In order to avoid the traffic congestion, a detour route that bypasses a part of the set route is set, and this detour route is incorporated into the set route and the set route is changed.

  In the navigation device according to the present invention, the receiving means may be an FM radio or a mobile phone that acquires the set route and traffic information of roads around the set route.

  With this configuration, when the FM radio or the like acquires traffic information such as traffic jams in a part of the set route in the scrolling direction while the set route is displayed on the display means and is being scrolled, the traffic jam occurs. In order to avoid this, a detour route that bypasses a part of the set route is set, and this detour route is incorporated into the set route and the set route is changed.

  According to the navigation device of the present invention, while the set route is displayed on the display means and the scroll process is being performed, the receiving means acquires traffic information such as traffic congestion in a part of the set route in the scroll traveling direction. Then, a detour route that bypasses a part of the set route is set to avoid the traffic congestion, and the detour route is incorporated into the set route and the set route is changed. As a result, scroll processing along a detour route that avoids traffic jams is preferentially performed, so it is possible to know in advance that traffic jams have occurred in some of the set routes during scroll processing. At the same time, it is possible to know a detour route for avoiding such traffic congestion. Therefore, by actually driving the vehicle according to the changed set route, it is possible to arrive at the destination promptly without being involved in traffic jams.

It is a block diagram which shows the structure of the navigation apparatus which concerns on one Embodiment of this invention. It is a flowchart which performs the scroll process of the setting route (setting route) which considered traffic information, such as traffic congestion performed in the navigation apparatus shown in FIG. It is a figure which shows the state which displays the setting route | root on the display part of the navigation apparatus, and is scrolling along a setting route | root. In order to avoid traffic congestion while scrolling the set route, a detour route (a detour route) that bypasses a part of the set route in the direction of scrolling is set, and the vehicle is at the branch point to this detour route It is a figure which shows the state which reached. It is a figure which shows the state by which the question matter whether a scroll process is temporarily stopped at the branching point to the detour route, and a detour route is selected is displayed on the display part of a navigation apparatus.

It is a figure which shows the state which is scrolling the detour route changed to the setting route.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  A navigation device according to an embodiment of the present invention is configured as shown in FIG. In FIG. 1, the navigation apparatus 100 has a processing unit 12 composed of a computer unit (including a CPU). The processing unit 12 includes a GPS unit 17 and sensors 18 (gyro sensor, acceleration sensor) for providing position information necessary for vehicle navigation, and a storage unit 14 (for example, a hard disk unit) that stores map information and various information. It is connected. Further, the processing unit 12 includes a display unit 13 provided in the vehicle interior and configured by an LCD or the like, an operation unit 11 such as an operation button or a touch panel configured in the display unit 13, and a speaker 16 provided in the vehicle interior. An output circuit 15 for supplying an audio signal is connected.

  The processing unit 12 executes processing related to vehicle navigation based on the position information from the GPS unit 17 and the sensors 18 and the map information read from the storage unit 14. In the processing related to the vehicle navigation, for example, a route (route) from the vehicle position to the destination is searched and set based on the vehicle position obtained by the GPS unit 17 and the sensors 18 and the position of the destination, and the display unit The vehicle position and the set route are displayed together with the map related to navigation in FIG. 13, and guidance (display or voice output) related to the route guidance of the vehicle is performed. Further, an FM radio 19 is connected to the processing unit 12, and under the control of the processing unit 12, the FM radio 19 receives traffic information (VICS) from a predetermined FM broadcast in real time, and the information is displayed on the display unit 13. Are displayed as characters or graphics. Examples of the traffic information include traffic jams due to road construction, traffic jams due to traffic accidents, traffic jams due to traffic regulations, and natural traffic jams. In this embodiment, an FM radio capable of receiving a predetermined FM broadcast has been described as a receiving means for acquiring traffic information. However, it is particularly limited as long as it can receive (acquire) traffic information to be distributed. Instead, it may be a mobile phone or other receiving means.

  The processing unit 12 executes a scroll process for the set route in consideration of traffic information such as traffic jam according to the procedure shown in FIG. First, when the user operates the operation unit 11 and inputs a destination G, the processing unit 12 sets a route on which the vehicle from the current location S to the destination G should travel and displays the route on the display unit 13. (S11). At this time, the processing unit 12 sets the scale of the map displayed on the display unit 13 to a predetermined scale according to the distance from the current location S to the destination G. When the user performs a route confirmation operation for confirming the set route from the current location S to the destination G before the vehicle travels toward the destination G, the processing unit 12 displays the set route on the display unit 13. The scroll process is started (S12). And the processing unit 12 performs the scroll process, confirming whether the scroll to the destination G was complete | finished (S13) (S14). As shown in FIG. 3, the scroll process along the set route is performed by gradually moving the portion of the set route R displayed on the screen of the display unit 13 on which the vehicle mark M is displayed from the current position S to the destination G. It is to be moved. In FIG. 3, the screen of the display unit 13 is shown to move with respect to the fixed setting route R, but actually, the setting route R displayed on the fixed display unit 13 is displayed. Move (the same in FIGS. 4, 6 and 7).

  The scrolling process along the set route is relatively time-consuming because it is performed while guiding left and right turns at intersections of general roads and entrances to expressways. The processing unit 12 performs the scrolling process (S14) along the set route, and further, the processing unit 12 displays the own information displayed on the screen of the display unit 13 based on the traffic information (VICS) received by the FM radio 19. The road traffic situation of the set route R ahead of the vehicle position M changes, that is, the road traffic situation of the set route to be scrolled changes, and a traffic jam J1 occurs in a part of the set route R to be scrolled from now on. It is determined whether or not (S15). If the processing unit 12 determines that the traffic jam J1 has occurred (YES in S15), the processing unit 12 may use a part of the set route to avoid the traffic jam J1, for example, as shown in FIG. A detour route U1 (route indicated by a broken line in FIG. 4) to be detoured is set and displayed on the display unit 13 (S16).

  When the detour route U1 is set and the scroll process is performed along the set route, and the vehicle mark M reaches the branch point to the detour route U1, the processing unit 12 temporarily performs the scroll process along the set route. For example, as illustrated in FIG. 5, the display unit 13 is displayed with “YES” and “NO” selection buttons together with a question “Do you want to select a detour route?”. When the user operates the “YES” button on the display unit 13 to select the bypass route U1 (YES in S17), the processing unit 12 incorporates the bypass route U1 in the set route R as shown in FIG. That is, after changing a part of the set route R to the bypass route U1 (S18), as shown in FIG. 7, scroll processing is performed along the bypass route U1 incorporated in the set route R (S13, S14, S15). . The processing unit 12 repeats the above processing (S16, S17, S18) every time it determines that a part of the setting route to be scrolled is congested during the scroll processing (YES in S15). As a result, it is possible to know that a traffic jam J1 has occurred in a part of the set route during the scroll process along the set route R before actually driving the vehicle, and to avoid the traffic jam J1. It is possible to know the detour route U1 for the purpose. And the user can perform the simulation for drive | working the setting route | root R, avoiding traffic congestion, before an actual driving | running | working.

  On the other hand, as shown in FIG. 5, when the question item “Do you want to select a detour route?” Is displayed on the display unit 13, the user operates the “NO” button to change the detour route U <b> 1. If no selection is made (NO in S17), the processing unit 12 deletes the bypass route U1 from the display unit 13 (S19), and scroll processing along the initially set route R as shown in FIG. Are continuously executed (S14, S15, S13).

  In the above-described embodiment, when the branch point of the detour route U1 is reached during the scroll process along the set route R, the scroll process is temporarily stopped, and the user is notified of either the set route R or the detour route U1. However, the scroll process along the detour route U1 may be preferentially performed without temporarily stopping even if the branch point of the detour route U is reached during the scroll process. In the above embodiment, the scroll process along the set route R is performed before the vehicle travels. However, the scroll process along the set route R can be performed while the vehicle is traveling. In this case, scroll processing is performed along the set route from the current position of the traveling vehicle to the destination.

  As described above, the navigation device according to the present invention scrolls along a detour route that avoids traffic jams when traffic information such as traffic jams is acquired even during scroll processing of a set route. The present invention is useful as an in-vehicle navigation device that performs route guidance to a destination so that a user can select a set route or a detour route by giving priority to processing.
