  Embodiments of the present invention will be described with reference to the drawings.

  The in-vehicle device according to the embodiment of the present invention is configured as shown in FIG.

  In FIG. 1, the in-vehicle device 11 includes a processing unit 12 including a computer unit (including a CPU, a ROM, a RAM, an interface, a bus, and the like). The processing unit 12 includes an AV unit 15 capable of reproducing various sound sources and video sources (for example, CD and DVD), and a navigation unit 16 (GPS receiver, gyro equipment, acceleration sensor, etc.) capable of navigating the host vehicle. Are included). In addition, a speaker 18 is connected to the processing unit 12 via an output circuit 17. As a result, an audio signal related to processing by the AV unit 15 and the navigation unit 16 can be output as audio from the speaker 18 via the output circuit 17. In addition, the processing unit 12 includes a storage unit 20 (for example, a hard disk, a flash memory, etc.) capable of storing music information and map information used in the AV unit 15 and the navigation unit 16 and various information such as applications related to AV playback. And a display unit 21 that displays images and the like associated with various types of processing configured by an LCD and the like, and an operation unit 22 that can input instructions necessary for various types of processing formed on the display unit 21 in a touch panel format. Has been. The operation unit 22 includes an input button using a hard key in addition to the touch panel type described above.

  Further, the map information stored in the storage unit 20 includes position information of an entrance guide plate position indicating an entrance (IC) of a toll road including an expressway. As a result, the processing unit 12 displays the guidance route searched through the navigation unit 16 on the display unit 21, and further causes the vehicle (not shown) to detect an off-route point that has deviated from the guidance route. It is possible to detect the toll road entrance guide plate at the position, and to detect the distance between the guide plate and the off-route point, and the toll road entrance in the traveling direction after the off-route.

  In the on-vehicle device 11 described above, processing is performed in the procedure as shown in FIG.

  While the vehicle (not shown) is traveling on a general road based on route guidance by the navigation unit 16 of the in-vehicle device 11, the processing unit 12 determines whether the vehicle is off-route traveling off the guidance route (S11). ). When it is determined that the processing unit 12 has been off-routed from the guidance route (YES in S11), the processing unit 12 detects an off-route point that has deviated from the guidance route (S12: off-route point detection means). The processing unit 12 can detect the coordinate position of the off-route point by the GPS receiver of the navigation unit 16 or the like. When the processing unit 12 determines that the vehicle is not traveling off-route, the processing unit 12 continues to determine whether the vehicle is traveling off-route every predetermined time.

  The processing unit 12 determines whether or not the guidance route by the navigation unit 16 is via a toll road such as an expressway (S13), and determines that the route is not via a toll road (S13). NO), a new route display by the reroute function for returning the vehicle after the off-route to the original guidance route is displayed on the display unit 21 (S20). On the other hand, when the processing unit 12 determines that the guidance route passes through a toll road such as an expressway (YES in S13), the position of the entrance guide board of the toll road closest to the off-route point is detected. (S14: Entrance guide plate position detecting means). The processing unit 12 detects the position of the off-route point and the nearest entrance guide plate from the location information of the entrance guide plate of the toll road stored in the storage unit 20 (S14). The position information of the entrance guide board of the toll road including the expressway is included in the map information stored in the storage unit 20. In addition, the entrance guide board of the toll road closest to the off-route point includes the entrance guide board located on both the front side of the off-route point and the other side (the destination) of the off-route point on the driving route, The one closest to the off-route point is applicable.

  In addition to the case where the position of the off-route point and the nearest entrance guide plate is detected by the position information of the entrance guide plate stored in the storage unit 20 described above, image analysis of a captured image by an in-vehicle camera (not shown). It is also possible to detect by. For example, when off-road driving of a vehicle is detected while driving on a guidance route, the image of the front and rear of the off-route point is image-analyzed to detect the position of the toll road entrance guide board closest to the off-route point Can do. In this case, the processing unit 12 detects the position of the nearest entrance guide plate based on the image analysis and the position, speed, etc. of the vehicle detected by the navigation unit 16.

  For example, as shown in FIG. 3A, an entrance guide plate 32 of a toll road including a highway has characters ("" on the portion colored in green in the road traffic guide plate 31 displayed near the intersection of a general road. "Naka IC" entrance display). Since the traffic guide plate 31 has a blue background (sky blue) and the entrance guide plate 32 is colored with a green background, it can be easily distinguished from other destination indications ("Iwaki" characters). Become. In some cases, the entrance guide plate 32 of the toll road is displayed alone, but in this case, the colored display with the green background is the same.

  Next, the processing unit 12 determines whether or not the distance between the off-route point and the position of the entrance guide plate nearest to the off-route point is within a predetermined distance (S15: predetermined distance determination means). The above-mentioned predetermined distance is a distance that allows the driver to identify the entrance guide plate from the off-route point when the entrance guide plate is located ahead of the off-route point, and the entrance guide plate is located in front of the off-route point. When this is done, it is a distance that allows an off-route operation by looking at the entrance guide plate, and can be determined in consideration of the vehicle speed and the like. Therefore, when the entrance guide plate is a position ahead of the off-route point, the predetermined distance can be fixedly determined as a visible distance, but the entrance guide plate is located in front of the off-route point. Sometimes, the distance that can be operated off-route by looking at the entrance guide plate is a dynamic distance that varies depending on the speed of the vehicle. The predetermined distance is appropriately set in consideration of the above points. If the entrance guide plate and the off-route point are not within the predetermined distance (NO in S15), it is not an off-route that recognizes the display of the entrance guide plate, and it is not intended to change the entrance of the toll road. A new route display by the reroute function for returning the vehicle after the off route to the original guidance route is displayed on the display unit 21 (S20).

  When the processing unit 12 determines that the entrance guide plate and the off-route point are within a predetermined distance (YES in S15), the processing unit 12 is not within the predetermined distance range in the traveling direction of the vehicle traveling off-route and deviating from the guidance route. It is determined whether there is a toll road entrance (S16: toll road entrance judging means). The processing unit 12 can determine the presence or absence of another toll road entrance within a predetermined distance range in the traveling direction of the vehicle based on the map information stored in the storage unit 20, the route search function of the navigation unit 16, and the like. . Since the predetermined distance range is an off-route for changing the entrance of the toll road, it can be set within a range of several kilometers from the off-route point. When the processing unit 12 determines that there is no other toll road entrance in the traveling direction after the off-route (NO in S16), it is determined that the off-route travel is not intended to change the entrance of the toll road. A new route display by the reroute function for returning the vehicle to the original guidance route is displayed on the display unit 21 (S20).

  When the processing unit 12 determines that there is another toll road entrance within a predetermined distance range in the traveling direction after the off-route (YES in S16), the processing unit 12 inputs the setting for changing the toll road entrance to the other toll road entrance. A change display screen is created and displayed on the display unit (telop display) (S17: display control means). As the telop display, for example, as shown in FIG. 3B, a selection display 35 for selecting whether or not to change the entrance of the toll road is displayed on the display unit 21 (an alternative selection display whether or not to change the entrance). Applicable. With such a display format, it is only necessary for a traveling driver to select either one by a touch operation, so that the entrance to the toll road can be changed with an easy operation.

  The processing unit 12 obtains whether or not the entrance change of the toll road is changed in the selection display 35 displayed in the telop on the display unit 21 (S18), and when it is selected not to change the entrance (NO in S18), the processing unit 12 is turned off. A new route display by the reroute function for returning the vehicle after the route to the original guidance route is displayed on the display unit 21 (S20). On the other hand, when the entry change is selected (YES in S18), the processing unit 12 changes the guide route with the entrance of the toll road as another toll road entrance (S19: guide route change setting means), and reroutes. Update and display on the display unit 21 (S20: display control means).

  After the reroute update is displayed, the processing unit 12 determines whether or not the vehicle has entered the toll road from the above other toll road entrance (new IC) (S21), and the toll road entrance When it is before entering from (NO in S21), it is detected whether or not the vehicle is off-route driving deviating from the reroute updated guide route, and reroute update or the like is performed by further changing the toll road entrance ( S11 to S20). On the other hand, when it is determined that the vehicle has entered from the entrance of the toll road (YES in S21), the processing is terminated because reroute update by changing the entrance is unnecessary.

  As described above, even when the guidance route is off-routed for the purpose of changing the entrance of the toll road during the guidance route traveling by the navigation function of the in-vehicle device 11 due to road congestion, etc. Since the reroute is updated to guide the route from the new entrance, a complicated change setting operation as in the past becomes unnecessary. Therefore, even if the vehicle is not stopped, reroute updating can be performed for route guidance from a new entrance while maintaining safe traveling.

  As described above, according to the present invention, when the guidance route is off-routed to change the entrance of the toll road, it is possible to change and change the entrance of the toll road without requiring a complicated operation. The reroute from the entrance to the destination is renewed, and it is possible to receive a new route guidance, which is useful as an in-vehicle device that guides the route of the vehicle from the departure point to the destination.
