  Embodiments of the present invention will be described using the drawings.

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

  In FIG. 1, the in-vehicle apparatus 11 has a processing unit 12 configured by a computer unit (for example, 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, CDs and DVDs) and a navigation unit 16 (GPS receiver, gyro device, acceleration sensor, etc.) capable of navigating the host vehicle. ) Is connected. In addition, a speaker 18 is connected to the processing unit 12 via an output circuit 17. As a result, it becomes possible to output an audio signal related to processing by the AV unit 15 and the navigation unit 16 as audio from the speaker 18 via the output circuit 17. In addition, the storage unit 20 (for example, a hard disk, a flash memory, etc.) capable of storing various information such as music information and map information used in the AV unit 15 and the navigation unit 16 in the processing unit 12 Connected to the display unit 21 for displaying an image or the like associated with various processes configured by an LCD or the like, and the operation unit 22 capable of inputting an instruction necessary for various processes formed in a touch panel format on the display unit 21. It is done. In addition to the touch panel type described above, the operation unit 22 also includes an input button using a hard key.

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

  In the on-vehicle apparatus 11 described above, the process is performed according to the procedure as shown in FIG.

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

  The processing unit 12 determines whether the navigation route by the navigation unit 16 is via a toll road such as a freeway (S13), and when it is determined that the route is not via a toll road (S13) NO), a new route display by the reroute function for the vehicle after the off route to return 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 the toll road such as the expressway (YES in S13), the position of the entrance guide plate of the toll road closest to the off route point is detected. (S14: entrance guide plate position detection means). The processing unit 12 detects the position of the off route point and the nearest entrance guide plate from the position information of the entrance guide plate of the toll road stored in the storage unit 20 (S14). The position information of the entrance guide plate of the toll road including the expressway is included in the map information stored in the storage unit 20. The entrance guide plate of the toll road closest to the off-route point is one of the entrance guide plates located on the near side of the off-route point and on the other side of the off-route point The one closest to the off-route point is relevant.

  In addition to the case of detecting the position of the off-route point and the nearest entrance guide plate based on the position information of the entrance guide plate stored in the storage unit 20 described above, the image analysis of the photographed image by the on-vehicle camera (not shown) It is also possible to detect by For example, when off-route travel of a vehicle is detected while traveling on a guidance route, the position of the entrance guide plate of the toll road closest to the off-route point is detected by analyzing the images taken before and after the off-route point. Can. In this case, the processing unit 12 detects the position of the nearest entrance guide plate based on the position, speed, etc. of the vehicle detected by the navigation unit 16 together with the image analysis.

  For example, as shown in FIG. 3A, the entrance guide plate 32 of the toll road including the expressway is a letter ("" in the portion where the ground is colored green in the road traffic guide plate 31 displayed near the intersection of the general road. It is displayed at the entrance display of Naka IC. Since the base of the traffic guide plate 31 is blue (sky blue), and the entrance guide plate 32 is colored green in it, it is easy to distinguish it from other destination indications (the characters “Iwaki”) Become. In addition, although the entrance guidance board 32 of a toll road may be displayed independently, a foundation | substrate is a green colored display also in this case similarly.

  Next, the processing unit 12 determines whether the distance between the off-route point and the entrance guide plate position closest to the off-route point is within a predetermined distance (S15: predetermined distance determination means). The above predetermined distance is a distance at which the driver can distinguish 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 positioned in front of the off-route point When doing this, the distance at which the off-route operation can be performed by looking at the entrance guide plate can be determined in consideration of the speed of the vehicle and the like. Therefore, when the entrance guide plate is at a position ahead of the off-route point, the predetermined distance can be fixedly determined by the visible distance, but the entrance guide plate is located in front of the off-route point When looking at the entrance guide plate, the distance that can be operated off-route results in a dynamic distance that varies depending on the speed of the vehicle. The predetermined distance is appropriately set in consideration of the above points. When the entrance guide plate and the off-route point are not within the predetermined distance (NO in S15), it is not the off-route for recognizing 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 the vehicle after the off route to return to the original guided 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 the predetermined distance (YES in S15), the processing unit 12 deviates from the guidance route and falls within the predetermined distance range of the traveling direction of the vehicle traveling off-route. It is determined whether there is a toll road entrance (S16: toll road entrance determination 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 and the route search function of the navigation unit 16 or the like. . The above-mentioned predetermined distance range can be set within a range of about several kilometers from the off-route point because it is an off-route for changing the entrance of the toll road. 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 assumed that off-route travel does not intend to change the toll road entrance. A new route display by the reroute function for the vehicle to return to the original guidance route is displayed on the display unit 21 (S20).

  If the processing unit 12 determines that there is another toll road entrance within the predetermined distance range in the traveling direction after the off route (YES in S16), the change setting of the toll road entrance to the other toll road entrance is input A change display screen to be displayed 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, the display section 21 asks the presence or absence of the entrance change of the toll road. Applicable With such a display format, even for the driver who is traveling, one of them may be selected by the touch operation, and the entrance change of the toll road can also be performed by the easy operation.

  The processing unit 12 determines the presence or absence of the entrance change of the toll road in the selection display 35 in telop display on the display unit 21 (S18), and turns off when no entry change is selected (NO in S18). A new route display by the reroute function for the vehicle after the route to return to the original guidance route is displayed on the display unit 21 (S20). On the other hand, when the entrance change is selected (YES in S18), the processing unit 12 changes the guidance route with the entrance of the toll road as another entrance to the toll road (S19: guidance route change setting means), It updates and displays on the display part 21 (S20: display control means).

  After the display of the reroute update described above is performed, the processing unit 12 determines whether or not the vehicle has entered the toll road from the other toll road entrance (new IC) described above (S21), and the toll road entrance If it is before the entry from the road (NO in S21), it is detected whether or not the rerouted off-route travel has deviated from the rerouted guidance route, and re-route update etc. are performed by changing the toll road entrance further ( S11 to S20). On the other hand, when it is determined that the vehicle has entered from the toll road entrance (YES in S21), the process is terminated because the reroute update is not necessary due to the entrance change.

  As described above, even when the guidance route is off-route for the entrance change of the toll road due to congestion of the road or the like while traveling the guidance route by the navigation function of the in-vehicle device 11, only by selecting the entrance change Since rerouting is updated to route guidance from the new entrance, complicated change setting operation as in the past is not necessary. Therefore, even if the vehicle is not stopped, it is possible to update the route to route guidance from the new entrance while maintaining safe traveling.

  As described above, according to the present invention, when the guidance route is off-routed for the entrance change of the toll road, the change setting of the entrance of the toll road can be made without requiring complicated operations. The reroute from the entrance to the destination is updated, and new route guidance can be received, which is useful as an on-vehicle device that guides the route of the vehicle from the departure location to the destination.
