  By the way, in the smart IC, for example, as shown in FIG. 3, one highway 1 capable of heading toward the A city direction has only the entrance 2 and resists the A city direction. There is a smart IC 5 that has only an exit 4 for the other highway 3 (that is, the opposite lane of one highway 1) that can be headed toward the B city.

  In such a smart IC 5, for example, a user's vehicle traveling on the other highway 3 in the direction of city B exits from the other highway 3 at the exit 4 for convenience, and then again. In the case of going to the direction of city B, the same smart IC 5 with the expectation that the user will have an entrance to the highway 3 in the smart IC 5 where the exit 4 from the other highway 3 was located. The possibility of returning to is fully considered.

  However, even when returning to the same smart IC 5 under such an expectation, the entrance to the other highway 3 is not found, and the result is that the other highway 3 cannot be entered.

  Further, in the smart IC 5 of FIG. 3, for example, a user's vehicle entering the one highway 1 from the entrance 2 in the smart IC 5 in the direction of the city A travels to the city B for convenience. When traveling on one expressway 1 on the way back, the smart IC 5 is expected with the expectation that the user will also have an exit 2 from the expressway 1 because there was also an entrance 2 to the other expressway 1. The possibility of traveling to the position of is fully considered.

  However, even if the vehicle travels to the position of the smart IC 5 under such an expectation, the exit is not found, and the result is that it is impossible to exit from one highway 1.

  In this way, conventionally, a user tries to perform a driving (entering the highway or leaving the highway) that is impossible due to the structure of the entrance to the highway or the exit from the highway in the smart IC. As a result, there has been a problem that a useless driving operation is performed.

  Therefore, the present invention has been made in view of such problems, and it is obviated that the user tries to travel impossible due to the structure of the entrance to the expressway or the exit from the expressway at the interchange.

A determination means for determining whether or not the interchange is a specific interchange that does not have an entrance of the vehicle, and the interchange detected by the determination means that the vehicle has exited the expressway is the specific interchange When the determination result is obtained, the entrance existing in the interchange where the vehicle has been detected to have exited the expressway is It is characterized in that a guide means for guiding the information indicating serial only entrance to the first highway.

  And according to such a structure, it can avoid beforehand that a user tries to enter the 2nd highway in the interchange where the entrance to the 2nd highway does not exist by guidance of information by a guidance means. it can.

  According to a second aspect of the present invention, there is provided an interchange information guidance apparatus according to the present invention, wherein a detecting means for detecting that the own vehicle has entered the expressway at the interchange, and that the own vehicle has entered the expressway by the detecting means. The detected interchange does not have an exit from the first highway toward the first direction and has an exit from the second highway toward the second direction against the first direction A determination means for determining whether or not the vehicle is a specific interchange, and a determination result indicating that the interchange detected by the determination device as having entered the expressway is the specific interchange. The exit that exists in the interchange where the vehicle is detected to have entered the expressway is the second expressway. It is characterized in that a guide means for guiding the information to the effect that only et outlet.

  Hereinafter, an embodiment of an interchange information guidance apparatus according to the present invention will be described with reference to FIGS. 1 and 2.

  Note that portions having the same or similar basic configuration as those of the related art will be described with the same reference numerals.

  As shown in FIG. 1, the interchange information guidance device 7 in this embodiment is roughly divided into a CPU 10, a program storage unit 11, a GPS receiver 12, an autonomous navigation sensor 14, a map storage unit 15, respectively connected to a system bus 8. It is comprised by the ETC onboard equipment 16, the display 17, and the speaker 18. As shown in FIG.

  Note that the interchange information guidance device 7 in this embodiment is integrated with an in-vehicle navigation device that can guide the host vehicle from the current location to the destination.

  The CPU 10 performs various processes and controls for guiding interchange information to be described later. The CPU 10 is also capable of executing functions as an in-vehicle navigation device, such as a map display function, a route calculation function, a route guidance function, and the like.

  The program storage unit 11 stores an execution program of the CPU 10, and the CPU 10 executes processing and control corresponding to the execution program by executing the execution program stored in the program storage unit 11. ing.

  The GPS receiver 12 receives information on the orbit and time (hereinafter referred to as GPS information) from a GPS satellite (not shown), and outputs the received GPS information to the inside of the interchange information guide device 7.

  The autonomous navigation sensor 14 detects the vehicle speed and acceleration of the host vehicle, and outputs the detection result to the inside of the interchange information guide device 7.

  The map storage unit 15 stores map data, and the map data includes data related to interchange such as smart ICs.

  The CPU 10 will be described in more detail. The CPU 10 includes a host vehicle position calculation unit 19, which outputs GPS information output from the GPS receiver 12 and the autonomous navigation sensor 14. Each detected result is inputted.

  And the own vehicle position calculation part 19 performs the satellite navigation which measures an own vehicle position as an absolute position based on the input GPS information. Further, the vehicle position calculation unit 19 performs autonomous navigation that measures the vehicle position as a relative change (relative position) from the previous vehicle position based on the detection result of the input autonomous navigation sensor 14. It has become. Further, the own vehicle position calculation unit 19 uses the map data stored in the map storage unit 15 when the own vehicle position calculated by satellite navigation or autonomous navigation is not on the road on the map. Map matching processing is performed to match the position with the corresponding position on the road in the map data.

  Further, the CPU 10 has a detection unit 20 as detection means, and this detection unit 20 is high-speed when the own vehicle passes through the ETC gate of the exit toll gate at the interchange by communication with the ETC on-vehicle device 16 or the like. It detects the exit from the road. Further, the detecting unit 20 detects that the own vehicle has passed through the ETC gate of the entrance toll gate and entered the expressway by communication with the ETC on-vehicle device 16 or the like.

  Furthermore, the CPU 10 includes a determination unit 21 as a determination unit. This determination unit 21 performs this detection when the detection unit 20 detects that the host vehicle has exited the expressway. The map data corresponding to the vehicle position indicated by the calculation result of the vehicle position calculation unit 19 is read from the map data storage unit 17.

  And the determination part 21 is based on this read map data, and the entrance to the 1st highway in which the interchange from which it was detected that the own vehicle came out of the highway went to arbitrary 1st directions And whether or not it is a first specific smart IC that does not have an entrance to the second highway toward the second direction against the first direction (hereinafter referred to as the first smart IC) Judgment).

  Furthermore, when the detection unit 20 detects that the own vehicle has entered the highway, the determination unit 21 indicates the own vehicle indicated by the calculation result of the own vehicle position calculation unit 19 when this detection is performed. Map data corresponding to the position is read from the map data storage unit 17.

  Then, the determination unit 21 outputs an exit from the third highway where the interchange where the own vehicle is detected to enter the highway is directed to the arbitrary third direction based on the read map data. And whether or not the second specific smart IC has an exit from the fourth highway heading toward the fourth direction against the third direction (hereinafter referred to as the second smart IC). Judgment).

  Depending on the structure of the smart IC doorway, the third direction (in other words, the third highway) is the same direction (highway) as the first direction (first highway), The fourth direction (fourth highway) may be the same direction (highway) as the second direction (second highway). For example, the smart IC 5 shown in FIG. 3 corresponds to such a case. That is, as shown in FIG. 3, one highway 1 having only the entrance 2 is the first highway toward the first direction (A city direction) and the third highway (A city direction). The other expressway 3 corresponding to the expressway No. 3 and having only the exit 4 is the second expressway going to the second direction (B city direction) and the fourth direction going to the fourth direction (B city direction). This corresponds to the expressway.

  Returning to FIG. 1, the CPU 10 has a guide unit 22 as a guide means. This guide unit 22 displays the interchange information according to the determination result of the determination unit 21 on the display 17 and the image display. This is performed by at least one of voice guidance from the speaker 18.

  That is, the guide unit 22 determines that the interchange in which the vehicle is detected to have exited from the expressway is the first specific smart when a positive determination result is obtained in the first determination by the determination unit 21. In the case of the IC, it is indicated that the entrance existing in the interchange (that is, the first specific smart IC) where it is detected that the own vehicle has exited the expressway is only the entrance to the first expressway. Interchange information is provided.

  In addition, when a positive determination result is obtained in the second determination by the determination unit 21, that is, the guide unit 22 indicates that the interchange detected that the vehicle has entered the highway is the second specific smart. In the case of the IC, the exit that exists in the interchange (that is, the second specific smart IC) in which it is detected that the host vehicle has entered the highway is only the exit from the fourth highway. Interchange information is provided.

  According to the above configuration, for example, in the smart IC 5 shown in FIG. 3, the own vehicle that was traveling on the other highway 3 in the direction of the city B moves to the exit 4 (that is, the ETC gate of the exit toll gate). ) Through the other highway (corresponding to the second highway) 3, when exiting the highway 3, one of the entrances existing in the smart IC 5 of FIG. The interchange information indicating that only the entrance 2 to the expressway 1 (corresponding to the first expressway) 1 is provided.

  By performing such interchange information guidance, it is impossible for the user to exit the other highway 3 through the exit 4 in the smart IC 5 and then enter the other highway 3 again in the same smart IC 5. An attempt to travel can be avoided in advance.

  Further, according to the above configuration, for example, in the smart IC 5 shown in FIG. 3, the own vehicle is going to the direction of the city A from the entrance 2 of the smart IC 5 to one highway 1 (corresponding to the third highway 3), when the highway 1 is entered, the guide unit 22 causes the exit existing in the smart IC 5 in FIG. 3 to be the exit 4 from the other highway (corresponding to the fourth highway) 3. Interchange information to the effect that it is only will be performed.

  By performing such interchange information guidance, the user enters the highway 1 through the entrance 2 in the smart IC 5 and heads toward the city A, and then visits the city B to return. When traveling on one highway 1, it is possible to avoid an attempt to perform an impossible travel such as exiting from one highway 1 in the same smart IC 5.

  Next, the operation of this embodiment will be described.

  In this embodiment, first, in step 1 (ST1) of FIG. 2, the determination unit 21 determines whether or not the detection unit 20 detects that the host vehicle has entered the expressway at the interchange, and is detected. If not, the process proceeds to step 2 (ST2). If not detected, the process proceeds to step 4 (ST4).

  In step 2 (ST2), the determination unit 21 performs the second determination, that is, the interchange in which the host vehicle is detected to have entered the highway in step 1 (ST1) is directed to an arbitrary third direction. Whether the second specific smart IC has no exit from the third highway and has an exit from the fourth highway toward the fourth direction against the third direction. Judgment is made.

  If a positive determination result is obtained in the second determination, the process proceeds to step 3 (ST3), and if a negative determination result is obtained, the process ends.

  On the other hand, in step 4 (ST4), the determination unit 21 determines whether or not the detection unit 20 has detected that the host vehicle has exited the expressway at the interchange. ), If not detected, return to step 1 (ST1).

  In step 5 (ST5), the determination unit 21 makes the first determination, that is, the interchange in which it is detected in step 4 (ST4) that the vehicle has exited the expressway heads for an arbitrary first direction. Whether or not the first specific smart IC has an entrance to the first highway and does not have an entrance to the second highway toward the second direction against the first direction. Make a decision. If a positive determination result is obtained in the first determination, the process proceeds to step 6 (ST6), and if a negative determination result is obtained, the process ends.

  Next, in step 3 (ST3), the guide unit 22 detects the exit existing in the interchange (second specific smart IC) in which the host vehicle is detected to have entered the highway in step 1 (ST1). Interchange information indicating that there is only an exit from No. 4 expressway is guided and the process is terminated.

  On the other hand, in Step 6 (ST6), the entrance that exists in the interchange (first specific smart IC) where the guide unit 22 detects that the host vehicle has left the highway in Step 4 (ST4) is the first. The interchange information indicating that only the entrance to the 1 expressway is provided is guided to the end of the process.

  As described above, according to the present embodiment, the guidance of the interchange information by the guide unit 22 makes it possible for the user to make a driving impossible due to the structure of the entrance to the highway or the exit from the highway in the smart IC. Since this can be avoided, the expressway can be used effectively.

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

  For example, the guide unit 22 indicates that an interchange indicating that the entrance to the first specific smart IC in which the detection unit 20 has detected that the host vehicle has exited the highway is only the entrance to the first highway. When the information is guided, information on the nearest interchange of the first specific smart IC that has an entrance to the second highway may be guided together.

  Similarly, the guide unit 22 indicates that the exit existing in the second specific smart IC in which the detection unit 20 has detected that the host vehicle has entered the highway is only the exit from the fourth highway. When the interchange information is guided, information on the nearest interchange of the second specific smart IC that has an exit from the third expressway may be guided together.

  An interchange other than the smart IC can also be applied to the determination target by the determination unit 21 and the guidance target of the presence / absence of the entrance / exit by the guide unit 22 associated therewith.
