Description

  The present invention relates to a system that performs control to output information related to a restricted section of a motorcycle on a highway, and a navigation system and program including the system.

  In general, a motorcycle can travel on all roads on which ordinary vehicles can travel. The same applies to the expressway, but the expressway has a motorcycle restricted passage defined by the Road Traffic Law. For example, on the Tokyo Metropolitan Expressway, there is a two-passage section for motorcycles.

  On motorcycles on the Metropolitan Expressway, motorcycles are normally marked with a two-passenger prohibited road sign indicating a two-passenger prohibited section, but this road sign is at the start of a two-passenger prohibited section. There are many cases. In addition, unlike ordinary roads, expressways have restricted exits. Therefore, even if a motorcycle rider riding two people notices a road sign in a two-passenger prohibited section, it may not be possible to immediately avoid entering the two-passenger prohibited section. In particular, if you do not know the two-passenger prohibited section, you may accidentally enter the two-passenger prohibited section of the expressway.

  In contrast, if it is detected that two people are riding in a motorcycle, if the destination is set, the route to the destination will be guided, excluding the two-passenger section of the Metropolitan Expressway A navigation system is disclosed (see Patent Document 1).

JP 2010-122093 A

  However, the navigation system described in Patent Document 1 functions only when the destination is set. When the destination is not set, information on the two-passenger prohibited section of the motorcycle is set. Is not output. For this reason, when traveling without setting a destination, there is a risk of accidentally entering a two-passenger prohibited section of the Metropolitan Expressway.

  In addition, traveling on a highway is faster than traveling on a general road, and a motorcycle traveling on a general road is easier to turn than a four-wheeled vehicle such as an ordinary car, for example. . For this reason, if the warning for entering a two-passenger prohibited section of a motorcycle is set uniformly during highway driving and general road driving, the motorcycle may enter the two-passenger prohibited section. is there.

  Therefore, an object of the present invention is to provide a system, a navigation system, and a program that can appropriately avoid the entry of a motorcycle to a restricted traffic section on a highway.

  (1) A system that performs control to output information related to a restricted section of a motorcycle on a highway, and determines whether the highway or a general road is being traveled, and is traveling on a highway or a general road A system characterized by changing a warning method for information on entry into the restricted traffic section.

  According to this, even if the rider of the motorcycle does not know the motorcycle traffic restriction section (hereinafter simply referred to as “traffic restriction section”) on the highway, the rider can easily deal with the traffic restriction section. Entry into can be avoided appropriately. Specifically, a highway has a higher speed limit than a general road, and thus travel speed is increased. In addition, entrances and exits of expressways are restricted to interchanges, but ordinary roads do not have such restrictions. In this way, since the driving situation differs between highway driving and general road driving, changing the warning method between highway driving and general road driving makes it easy to deal with restricted traffic sections and restricts traffic. Entering the section can be avoided appropriately.

  As a warning method, it is preferable to change the warning control for outputting information related to the entry to the restricted traffic section between highway driving and general road driving. In particular, it is preferable to perform warning control that outputs timing and content information suitable for the traveling state of the motorcycle due to the difference between traveling on an expressway and traveling on a general road. By performing warning control of the timing and content suitable for the driving situation, it becomes possible to give the rider the optimal warning regarding the restricted road section of the motorcycle on the expressway, and it is safe to avoid entering the restricted traffic area Will be able to.

  As a method of informing information, it is good to carry out by one or both of notification by voice and notification displayed on a map displayed on a monitor or the like. When performing voice notification, it is preferable to use a headset having an earphone, a microphone, or the like that can be worn while wearing a helmet. It is more preferable to use a wireless headset capable of wireless communication. As the information to be output by voice, it is preferable to notify the relative position, the specific interchange name, the direction, the fact that it is a traffic restriction section, and the like. For example, if you are driving on a highway, you will be informed that “This is the area ahead of the Shibaura exit on the expressway and is a motorcycle-ridden section.” In the direction of the motorcycle, two-passengers are prohibited. ” In addition, when traveling on an expressway, if it is necessary to always exit the expressway in order to avoid the restricted traffic section, it is better to output a voice that guides the exit immediately before the start of the restricted traffic section.

  In the case of performing notification for displaying information on a map, a monitor on which waterproof processing, drip-proof processing, dust-proof processing, or the like is applied may be used. The monitor can be supplied with power from the battery of the motorcycle, and more preferably can be operated easily even in a gloved state. Further, the map information of the map displayed on the monitor may include information on the position of the interchange and information indicating that the destination of the interchange is a restricted passage section. In order to make it easier to understand the relative position of the interchange on the map, it is better to mark the corresponding interchange with a circle or the like.

  In addition, for example, when the system mistakenly detects traveling on a highway and traveling on a general road, such as when a highway and a general road are running side by side, the miscorrection is corrected using a general correction function. It is also possible to adopt a configuration in which the rider operates and corrects by himself / herself.

  Further, when the rider has set a two-seater (hereinafter referred to as “two-seater setting”), it may be configured to output information related to entering the restricted traffic section. In particular, when the single rider is set by the rider, it may be configured not to output information related to entering the restricted traffic section. For example, it may be configured to allow the rider to set whether to take two people when starting the engine. By setting the rider, you can make the rider aware of being a two-seater and drive safe driving. The factory default setting should be two-seater. In this way, it is possible to solve the problem that the two-seater setting is forgotten and no warning is given. On the other hand, it is good also as a structure which warns a traffic restriction area irrespective of a rider's setting. It is possible to raise awareness of restricted traffic zones by outputting information even when you are traveling alone. In this case, it is preferable to provide an information output stop function. This is because there are riders that cannot ride two people and motorcycles that are exclusively for single riders.

  In addition, for example, it may be configured to output information related to the restricted traffic section regardless of whether or not the destination is set by a navigation system or the like having a guidance function.

  (2) It is characterized in that the timing for outputting information related to the entry into the restricted traffic section is changed between traveling on a highway and traveling on a general road.

  In this way, since traveling speed and road configuration differ between highway traveling and ordinary road traveling, by changing the timing of information output, it is possible to warn of entering the restricted traffic section without waste, and It can be safely avoided.

  For example, since a highway has a speed limit higher than that of a general road and a traveling speed is often faster than that of a general road, information may be output earlier during traveling on a highway than during traveling on a general road. On the other hand, general roads have more choices of travel routes than expressways, and there are cases where the route is changed before reaching the entrance of the restricted traffic section, so if the timing of information output is too early, warnings are wasted turn into. For this reason, it is preferable to output information later when traveling on a general road than when traveling on a highway.

  The timing for outputting the information may be set according to the distance to the start point of the restricted traffic section (when traveling on an expressway) or the entrance within the restricted traffic section (when traveling on a general road). Moreover, you may set according to the distance to the branch to the exit right before an access restriction area instead of the start point of an access restriction area, or the branch toward an exit. Furthermore, you may set according to the arrival time to the branch which goes to the entrance to a traffic restriction area, the starting point of a traffic restriction area, the exit right before a traffic restriction area, or the exit toward the last exit. In this case, for example, the time required to reach the branch to the exit immediately before the restricted traffic section may be calculated from the traveling speed and notified. Moreover, this is still better if it is the structure which alert | reports several times like 10 minutes ago and 5 minutes ago.

  (3) During highway driving, information is output when the distance to the start point of the restricted traffic section is equal to or less than the first distance, and during general road traveling, the distance to the entrance of the restricted traffic section is Information is output when the distance is equal to or shorter than a second distance shorter than the first distance.

  In this way, it is possible to output information related to the approach to the restricted traffic section at a suitable timing during traveling on a highway and traveling on a general road. The first distance may be different from the second distance so that the digit changes in terms of meters, and more preferably a difference of 10 times or more.

  As the first distance during traveling on the highway, for example, the distance to the starting point of the restricted traffic section may be set to several km, and particularly set to 2 km. By setting the distance to 2 km, it becomes the same as the guidance distance of a general navigation system, so that the sense of distance is easy to grasp, and it is optimal for alerting for avoiding entry.

  As a 2nd distance during driving | running | working on a general road, it is good to set the distance to a traffic restriction area to several hundred m, for example, and to set to 100 m especially. By setting it to 100 m, it is possible to easily avoid entering the traffic restricted section without wasting information output. For example, while traveling on a general road, the route may be changed before the entrance of the restricted traffic section, and does not necessarily pass along the entrance of the prohibited section. Therefore, if the information is notified early, the notification becomes unnecessary. In particular, a motorcycle is effective because it has a small route and many route options.

  (4) During traveling on an expressway, when the distance to the start point of the restricted traffic section is equal to or less than a third distance shorter than the first distance, information is output a second time.

  In this way, it is possible to reliably prevent entry into the restricted traffic section while traveling on an expressway. Further, even when the rider misses or misses information at the first distance, entry into the restricted traffic section can be avoided. As the third distance during traveling on the highway, for example, the distance to the start point of the restricted traffic section may be set to 1 km. By setting the distance to 1 km, even if the output of information at the first distance is overlooked or missed, entry into the restricted traffic section can be easily avoided.

  (5) During traveling on a general road, information is output when a motorcycle enters the area of the second distance centered on the entrance of the restricted traffic section.

  Unlike ordinary cars, motorcycles are easy to change course because of their small turns. In addition, there are cases where there are a plurality of ways to approach the entrance of a highway on a general road. Therefore, in this way, even if the motorcycle suddenly changes its course and tries to enter the entrance of the expressway, it is possible to output in advance information related to the restricted traffic section. Thereby, it is possible to prevent the motorcycle from entering the restricted traffic section from the general road.

  The region within the second distance may be, for example, within a region where the radius around the entrance of the restricted traffic section is the second distance or within a region around the second distance around the entrance of the restricted traffic zone. In addition, when the engine is turned off within the second distance area, it is more preferable that the information related to entering the prohibited passage section is output when the engine is started again.

  (6) During traveling on a general road, when there is a branch lane from the general road to the entrance of the expressway, the entrance of the branch lane is used as the entrance of the restricted traffic section.

  In this way, entry into the branch lane can be prevented without noticing that the end of the branch lane is the entrance of the restricted traffic section. In this case, the map information may include the presence or absence of a branch lane.

  (7) During traveling on an expressway, information is output when an exit before the exit immediately before the start point of the restricted traffic section is exceeded.

  If it does in this way, if information is output, what is necessary is just to get off at the next exit, and it can prevent that a rider mistakes an exit. For example, it is possible to prevent the vehicle from getting off at an exit before the exit that should be originally exited. In particular, if the expressway crosses the exit just before the start of the restricted traffic section, there is no exit to the exit just before the start of the restricted traffic section. There will be no mistakes.

  (8) The information related to the restricted traffic section output during traveling on an expressway includes a direction.

  In this way, by notifying the information including the direction, it is not necessary for the rider to get off the expressway in order to avoid the restricted traffic section. From the exit immediately before the starting point of the restricted traffic section, it is unnecessary. It can prevent getting off.

  For example, when traveling on a highway, it becomes a traffic restricted section when heading in the first direction, it is not a traffic restricted section when heading in the second direction, and it is not always necessary when it becomes an exit of a highway when heading in the third direction. You may not need to leave the highway. In this case, giving the rider information including the direction allows the rider to make an optimal selection. As the information including the direction, for example, it is preferable to output information on the direction in which entry is prohibited among the first to third directions, but it is more preferable to output information on the direction in which entry is possible.

  During traveling on a general road, it is only necessary to determine whether or not the entrance of the expressway is a restricted passage section, so that it is not necessary to output direction information with respect to the traveling direction.

  (9) The information related to the restricted traffic section output during traveling on an expressway includes an interchange name of an exit immediately before the restricted traffic section.

  In this way, accurate information can be given to the rider by outputting information on the specific interchange name at the exit of the expressway. Therefore, it is possible to prevent the rider from making a mistake in the exit.

  (10) A navigation system comprising the above system and a guidance system capable of searching for a route to a destination when the destination is set and guiding the destination.

  According to this, it is possible to prevent the vehicle from entering the restricted traffic section while being guided to the destination by the guidance system. At this time, when the output of the destination guidance and the output of the information related to the approach to the restricted traffic section overlap, it is preferable to output the one detected first and then output the other.

  (11) The system is configured to be able to set whether or not it is possible to travel in the restricted traffic section, and the guidance system is configured such that the system is set so as not to travel in the restricted traffic section, When there is the traffic restriction section between the set destination and the route, the route excluding the traffic restriction section is searched and guided.

  In this way, it is possible to reliably prevent the vehicle from entering the restricted traffic section before reaching the destination. In addition, by setting the rider to make a setting, it is possible to make the driver aware of the fact that the travel restriction section is in an inoperable state and to keep safe driving in mind.

  (12) A program for causing a computer to function as the system.

  In this way, it is possible to provide a program that causes a computer to function as a warning system.

  According to the present invention, by changing the warning method for entering the restricted road section of the two-wheeled motor vehicle on the highway between driving on the highway and driving on the general road, the entry of the two-wheeled vehicle to the restricted traffic section is appropriately performed. A system that can be avoided, a navigation system including the system, and a program can be provided.

By using the coupling mechanism, the cradle body 30 can be tilted to an arbitrary posture in the three-dimensional direction with respect to the handle 101 to which the connecting portion is connected, and can hold the arbitrary posture.

  Next, the internal structure of the apparatus main body 2 will be described with reference to FIGS. FIG. 3 is a functional block diagram of the navigation device 1 according to the present embodiment. FIG. 4 is a diagram showing a motorcycle two-passenger prohibited section on the Metropolitan Expressway. FIG. 5 is a diagram illustrating a start point of a two-passenger prohibition section displayed on the display unit 21 and an interchange in the two-passenger prohibition section. FIG. 6A is a diagram illustrating a start point of a two-passenger prohibition section displayed on the display unit 21, and FIG. 6B is a diagram illustrating an entrance of the two-passenger prohibition section.

  As shown in FIG. 3, the navigation device 1 includes a GPS receiver 40, an internal clock 41, a speaker 42, a database 43, and a control unit 44 in the device body 2.

  The GPS receiver 40 receives a GPS signal by the GPS antenna 40a, obtains a current position from the received GPS signal, and transmits position information (background, latitude) of the obtained current position to the control unit 44. The GPS signal includes date / time data, and the GPS receiver 40 transmits the date / time data included in the received GPS signal to the control unit 44. The internal clock 41 is provided so that time can be displayed on the display unit 21 even when GPS signals cannot be received. The internal clock 41 may be configured to be synchronized with the transmitted date / time data when the date / time data is transmitted by the GPS receiver 40.

  The speaker 42 outputs an operation sound when the rider operates the touch panel 22, a voice guidance by a navigation function, a warning voice of information related to entering a two-passenger prohibited section by a warning function, and the like.

  The database 43 includes road network information (including information on the location of the interchange on the Metropolitan Expressway shown in FIG. 4 and information that the destination of the interchange is a two-passenger section of a motorcycle), a telephone number and its telephone number. Phone number data that stores the address of the number, location information of the company, facility, etc. in association with each other, address data that stores the address in association with the location information of the address, the name of the facility, etc. Name data stored in association with information is stored. The information and data stored in the database 43 may be stored in advance as all the information and data of the whole country, or provided with information and data stored for each region. The user may select and use the external memory 200 storing information and data necessary for the user. In this case, the information and data stored in the external memory 200 may be transferred to the database 43 and stored, or the control unit 44 may access the external memory 200 to read out and use it.

  The control unit 44 is a microcomputer including a CPU, a ROM, a RAM, a nonvolatile memory, an I / O, and the like. The control unit 44 executes a predetermined process based on information input from the various devices described above, and sets the output device described above. It uses and outputs predetermined information. For example, the control unit 44 includes a general current position display function and a navigation function, and a warning function for a motorcycle entering the two-passenger prohibited section.

  The current position display function is a function of reading road network information around the current position from the database 43 based on the current position acquired from the GPS receiver 40 and displaying a map around the current position on the display unit 21. The current position display function is basically displayed constantly while the navigation apparatus 1 is powered on.

  The navigation function is a function that, when a destination is set, searches for a route to the destination and guides to the destination. Specifically, the control unit 44 displays a destination setting button on a map around the current position displayed by the current position display function. And the control part 44 performs a destination setting process, when the press of the position corresponding to the display position of the destination setting button is detected with the touch panel 22. FIG. In the destination setting process, a destination setting menu is displayed on the display unit 21 to prompt the user to select a destination setting method. The destination setting menu includes a telephone number search, an address search, and a name search.

  For example, when it is detected that a telephone number search button has been pressed, a telephone number input screen is displayed, and position information corresponding to the input telephone number is acquired from the corresponding database 43. If it is detected that the address search button has been pressed, an address input screen is displayed, and position information corresponding to the input address is acquired from the database 43. If it is detected that the name search button has been pressed, a name input screen is displayed, and position information corresponding to the input name is acquired from the database 43. Then, the acquired position information is set as the position information of the destination, and a recommended route from the current position to the destination is calculated based on the road network information stored in the database 43.

  At this time, when the rider has set the two-seater (hereinafter simply referred to as “two-seater setting”), the control unit 45 calculates a recommended route that avoids the two-passenger prohibited section. . Then, the calculated recommended route is displayed on the display unit 21 together with the surrounding map, and voice guidance to the destination is performed based on the recommended route.

  It should be noted that the two-seater setting is preferably performed when starting the two-seater, and if the two-seater setting is planned, the two-seater setting is preferably performed in advance.

  In addition, when a recommended route that avoids a two-passenger prohibited section is calculated, when avoiding a two-passenger prohibited section, it may be notified that if it is not avoided, the destination is a two-passenger prohibited section . In this way, the rider can be made aware of the two-passenger prohibited section. The notification that it is a two-passenger prohibited section includes a notification that displays a two-passenger prohibited section on the map of the display unit 21 (hereinafter referred to as “warning display”), and a voice notification (hereinafter referred to as “warning display”). One of the “warning voice” may be performed, but both are better performed.

  For the warning display, it is preferable to use a display method such as a mark such as a circle or a pointer that makes it easy to recognize that the zone is a two-passenger prohibited section on the map. The warning sound may be performed via a headset having an earphone, a microphone, or the like that can be worn while wearing a helmet. By using the headset, the warning sound output from the navigation device 1 attached to the handle 101 of the motorcycle 100 can be easily heard. It is more preferable to use a wireless headset capable of wireless communication. In this way, since there is no wiring connecting the apparatus main body 2 and the earphone, the microphone, etc., there is no possibility that the wiring is caught and a problem of disconnecting occurs.

  The two-seater setting may be configured to be performed when a two-seater setting button is displayed on the display unit 21 and it is detected that the two-seater setting button is pressed. The timing for performing the two-seater setting (the timing for pressing the two-seater setting button) is set in advance when the engine of the motorcycle 100 is started, that is, after the power of the navigation device 1 is turned on by key operation, and before traveling. Good. In order to prevent forgetting to press before traveling, it is more preferable to display a message on the display unit 21 as to whether or not to set two-seater after the navigation apparatus 1 is turned on. In this way, by setting the rider to the two-seater setting, it is possible to make the rider aware of the fact that the two-seater or the two-seater rides, and to make the rider try to drive safely.

  The two-seater setting is not limited to the configuration in which the two-seater setting button is pressed. For example, when a sensor is provided on a tandem seat and the sensor detects that a person has got on the tandem seat, the two-seater setting is automatically performed. The configuration may be set.

  The warning function is a function for outputting information for preventing a two-seater motorcycle from entering a two-passenger prohibited section. In particular, this is a function for easily avoiding entry into a two-passenger prohibited section by changing the warning method during traveling on an expressway and traveling on a general road.

  Here, the two-passenger prohibited section of the motorcycle is set as a partial section of the Metropolitan Expressway. Specifically, as shown in Figure 4, the two-passenger prohibited section is the Tokyo Metropolitan Expressway Central Loop Line, No. 1 Ueno Line, No. 2 Meguro Line, No. 9 Fukagawa Line, No. 11 Daiba Line, Yaesu Line And all lines of the Tokyo Expressway Company Line, the No. 1 Haneda Line Shibaura exit to the downtown ring line connection, the down line from the downtown ring line connection to the Shibaura entrance, the No. 3 Shibuya Line Shibuya exit to the downtown ring line connection Up line to and down line from downtown ring line connection to central ring line connection Up line from Shinjuku exit of No. 4 Shinjuku line to downtown ring line connection and down line from downtown ring line connection to central ring line connection, Ascending line from Higashi-Ikebukuro Exit of the No. 5 Ikebukuro Line to the Tokyo Metropolitan Ring Line Connection and Down Line from the Central City Circular Line Connection to the Higashi-Ikebukuro Entrance Down to the entrance to Mukaishima, No.7 Komatsugawa Line Kinshicho is set from the up line and the No. 6 Mukojima line connection from the outlet to the No. 6 Mukojima line connected downline to Kinshicho inlet, the.

  The Metropolitan Expressway is limited to interchanges at the entrance. Therefore, if you pass through one interchange exit, you must travel on the Metropolitan Expressway to the next interchange exit. In other words, there are restrictions on getting on and off the Metropolitan Expressway. Thus, for example, taking the No. 1 Haneda Line as an example, if you pass the Shibaura exit while traveling on the No. 1 Haneda Line, you will inevitably enter the two-passenger prohibited section. End up. Therefore, a two-seater motorcycle traveling on the No. 1 Haneda Line up line must exit from the No. 1 Haneda Line up line at the Shibaura exit. Also, if you enter the No. 1 Haneda Line up line from the general road via the Shibaura entrance, you will inevitably enter the two-passenger prohibited section. For this reason, two-seater motorcycles traveling on ordinary roads must avoid entering the No. 1 Haneda Line from the Shibaura entrance.

  Furthermore, since the metropolitan expressway has a higher speed limit than ordinary roads, the traveling speed is often higher during traveling on the metropolitan expressway than during traveling on the general road. Therefore, for example, if a rider of a motorcycle riding two people traveling on the No. 1 Haneda Line up line notices that it is a two-passenger prohibited section just before the Shibaura exit, depending on the lane in which it is traveling It may be difficult to get off the Shibaura exit. On the other hand, general roads have few restrictions on entrances and exits like the Metropolitan Expressway, but there are many ways to approach the Metropolitan Expressway entrance. In particular, since a motorcycle has a small turn, it is easy to change the direction toward the entrance of the Metropolitan Expressway and can enter the entrance of the Metropolitan Expressway from various directions.

  Thus, it is necessary for a two-seater motorcycle to avoid entering the two-passenger prohibited section of the Metropolitan Expressway regardless of whether it is traveling on the Metropolitan Expressway or on the general road. The traveling situation of a motorcycle differs between traveling on an expressway and traveling on a general road. Therefore, the control unit 44 first determines whether the vehicle is traveling on the Metropolitan Expressway or on the ordinary road, and performs warning control for entering the two-passenger prohibited section when traveling on the Metropolitan Expressway and traveling on the ordinary road. By changing, entry into the two-passenger prohibited section is safely avoided. In this embodiment, by changing the timing of outputting information related to entry into a two-passenger prohibited section between traveling on the Metropolitan Expressway and traveling on a general road, the two-passenger prohibited section on the Metropolitan Expressway is changed. The entry is safely avoided. Hereinafter, the warning function of the control unit 44 according to the present embodiment will be specifically described.

  In this embodiment, the warning function functions even when the destination setting by the navigation function described above is not performed. In other words, even when touring where the destination is not determined, a warning is given regarding entry into the two-passenger prohibited section. Moreover, in this embodiment, it is set so that the warning regarding the approach to the two-passenger passage prohibited section is performed regardless of whether or not the two-seater setting is performed. By alerting even when two people are not riding, it is possible to make the rider aware of the two-passenger zone and easily avoid the two-passer zone when actually riding two people. It is to make it.

  If the two-seater setting is not performed, the recommended route for avoiding the two-passenger prohibited section is not calculated when the destination is set, but both a warning display and a warning sound are output. In addition, the navigation device 1 according to the present embodiment is also provided with a warning cancel function for entry into a two-passenger prohibition section. This is to accommodate a single-seat motorcycle and a single rider.

  First, the control unit 44 determines whether the motorcycle 100 is traveling on a metropolitan expressway or a general road. Whether the vehicle is traveling on a metropolitan expressway or a general road is determined based on the current position information acquired from the GPS receiver 40. At this time, if it is determined that the metropolitan expressway is traveling despite being on a general road, or if it is determined that the metropolitan expressway is traveling but it is determined that a general road is traveling, a general correction function Is used to correct erroneous detection. Description of this correction function is omitted.

  This correction may be performed by the rider himself. For example, when it is determined that the vehicle is traveling on a metropolitan expressway despite traveling on a general road, when the rider presses the traveling general road displayed on the display unit 21, the control unit 44 is traveling on the general road. It is good to correct it. Similarly, when it is determined that the vehicle is traveling on a general road despite traveling on the Metropolitan Expressway, when the rider presses the traveling Metropolitan Expressway displayed on the display unit 21, the control unit 44 causes the Metropolitan Expressway to It is good to correct while driving on the road.

  Next, when traveling on the Metropolitan Expressway, the control unit 44 outputs the first information when the distance to POI1 shown in FIG. 5 is 2 km, and the distance to POI1 is 1 km. In this case, the second information is output. The reason for giving the warning twice is to avoid the entry to the two-passenger prohibited section without fail.

  In FIG. 5, an exit lane toward the Kinshicho exit is provided by the start point (Kinshicho exit) of the two-passenger prohibited section, and POI1 is arranged at the start point of the exit lane. Therefore, a distance for outputting information is set with this POI 1 as the starting point of the two-passenger prohibited section. Thus, the start point of the two-passenger prohibited section is not necessarily the exit of the Metropolitan Expressway. As described above, if there is an exit lane, the start point of the lane is the two-passenger prohibited section. It is good also as a starting point. In other words, the starting point of the two-passenger prohibited section is a concept that includes not only the exit of the specified expressway but also the starting point when there is an exit lane or a branch lane. This is to allow the rider to safely avoid the two-passenger section.

  As information output, warning display on the display unit 21 and warning voice output are performed. As the warning display on the display unit 21, as described above, a display method such as a mark such as a circle or a pointer that makes it easy to understand that the zone is a two-passenger prohibited section on the map of the display unit 21 is used. Good. Only the two-passenger prohibited section may be displayed in a different color from other roads.

  As the content of the warning voice to be output, a relative position, a specific interchange name, a direction, a traffic restriction section, and the like are notified. For example, it is informed that “This is the area ahead of the Shibaura Expressway exit, which is a section where motorcycle riding is prohibited.” In addition, as shown in FIG. 6A, when there are a plurality of lanes, for example, when traveling in the left lane, it becomes a two-passenger prohibited section (Metropolitan Expressway Daiba Line), and when traveling in the central lane and the right lane, The direction of travel may be regulated by lanes, such as when the metropolitan expressway (Metropolitan Expressway Wangan Line) remains accessible for passengers. In this case, information including the direction, that is, lane information is given to the rider. For example, when the distance to POI 2 becomes 2 km and 1 km, respectively, “If you enter the left lane, you will be in the area from the Ariake Junction to the city center and the motorcycle prohibited area.”

  On the other hand, when traveling on a general road, when a motorcycle enters a region with a radius of 100 m centered on POI 3 shown in FIG. 5 arranged at the entrance in a two-passenger prohibited section of the Metropolitan Expressway, Output information. The reason why the radius of 100 m centered on POI3 is that if the distance to POI3 is set long, the information output timing is too early and the warning may be wasted. As shown in FIG. 6 (b), the area with a radius of 100m has more choices of travel routes than the Metropolitan Expressway, as shown in Fig. 6 (b), and before reaching the entrance in the two-passenger prohibited section This is because there is a possibility that it may not be possible to cope with a sudden change in the course of the motorcycle if only the distance in the advancing direction to POI4 and POI5 arranged at the entrance is determined. In addition, you may set this area | region to a 100m square area.

  In addition, when reaching the entrance in a two-passenger prohibited section via a branch lane from a general road, when a motorcycle enters an area with a radius of 100 m centered on the POI located at the entrance of the branch lane , Output information. That is, the entrance in the two-passenger prohibition section is a concept including the entrance of the branch lane when there is a branch lane toward the entrance. This is to allow the rider to safely avoid the two-passenger section.

  Furthermore, when the engine of the motorcycle 100 is turned off when it is within a radius of 100 m centered on the POI arranged at the entrance in the two-passenger prohibited section or the POI arranged at the entrance of the branch lane When the engine is started, information relating to the two-passenger prohibited section is output again. For example, when approaching a convenience store or the like within a radius of 100 m, a warning is output again so as to reliably avoid entry into a two-passenger prohibited section.

  Next, a method of using the navigation device 1 configured as described above when attached to the handle 101 of the motorcycle 100 will be described. In this embodiment, the case where a destination is set in the navigation device 1 and two-seater traveling is used, and the case where two-seater traveling without setting is used are described. Moreover, in the following embodiment, it demonstrates using the case where the audio | voice of the navigation apparatus 1 is output via the headset which has a wireless communication function.

  First, a case where a destination is set in the navigation device 1 and the vehicle travels with two people will be described. When the rider starts the engine of the motorcycle 100, the navigation device 1 is activated in conjunction with the key operation. When the navigation device 1 is activated, a map of the current position is displayed on the display unit 21 by the current position display function. When the map of the current position is displayed, a two-seater setting button and a destination setting button are displayed on the display unit 21. When the rider presses the two-seater setting button, the two-seater setting is made in the navigation device 1.

  Next, the rider presses the destination setting button to set the destination. When the destination is set, the position information of the set destination is acquired, and the acquired position information is set as the position information of the destination. Then, a recommended route from the current position to the destination is calculated based on the road network information stored in the database 43. In the present embodiment, since the two-seater setting is performed, the navigation device 1 determines the recommended route that avoids the two-passenger prohibited section when there is a two-passenger prohibited section between the destination and the destination. calculate. Then, the calculated recommended route is displayed on the display unit 21 together with the surrounding map, and voice guidance to the destination is performed based on the recommended route.

  If the two-seater setting is performed after the destination is set, the recommended route avoiding the two-passenger prohibited section is recalculated, and the voice guidance to the destination is based on the recalculated recommended route. I do.

  At this time, if a two-seater motorcycle approaches a two-passenger prohibited section that is avoided, a warning sound is output to the effect that the destination is a two-passenger prohibited section. For example, “If you enter the left lane after this point, it is from Ariake Junction to the city center and motorcycle prohibited area”. If it is necessary to perform both the warning voice and the guidance voice, the one detected first is output first, and the next is output after the first output ends. Priority.

  Next, a description will be given of a case where two people travel without setting a destination in the navigation device 1. Since the rider starts the engine of the motorcycle 100 and displays a map or the like of the current position, the description is omitted because it is the same as described above.

  When the rider starts traveling, the navigation device 1 determines whether the traveling road is a general road or a highway. This is determined based on the current position information received by the GPS receiver, and the traveling position is always displayed on the display unit 21 together with the map around the current position by the current position display function.

  Here, for example, it is assumed that a two-seater motorcycle 100 enters an area within a radius of 100 m at the interchange entrance of the Metropolitan Expressway while traveling on a general road. At this time, when the interchange entrance is an interchange entrance within a two-passenger prohibited section, the navigation device 1 marks the interchange entrance of the Metropolitan Expressway displayed on the display unit 21 with a relative position, Information such as a typical interchange name, direction, and traffic restriction section is notified by voice. For example, it is informed that “This is the area ahead of the Shibaura entrance on the expressway, which is a section where motorcycles cannot be used for two persons”. The rider recognizes that he / she cannot enter the Metropolitan Expressway from the Shibaura entrance ahead by obtaining the warning sound output via the headset.

  For example, if the rider stops at the convenience store in the area within 100m radius of the interchange entrance of the Metropolitan Expressway in the two-passenger prohibited section and starts the engine again, the engine is started again. Since it is re-notified when it is made, it is prevented that the rider forgets not to enter from the notified interchange entrance.

  Next, for example, it is assumed that a two-seater motorcycle 100 is traveling on a highway. At this time, when reaching a point 2 km away from the starting point of the two-passenger prohibited section, the navigation device 1 informs that this is a two-passenger prohibited section. Specifically, the two-passenger start point on the Tokyo Metropolitan Expressway displayed on the display unit 21 is marked with a circle, and the relative position, specific interchange name, direction, and traffic restriction section, etc. Information is notified by voice. For example, “This is the area ahead of the Shibaura exit on the expressway, which is an area where two passengers are prohibited from riding in Dubai”. The rider recognizes that he must exit the Metropolitan Expressway from the Shibaura exit ahead by obtaining a warning sound output via the headset. This warning sound is also output when a point of 1 km is reached from the start point of the two-passenger prohibited section.

  For example, when the traveling direction is defined by a plurality of lanes, the navigation device 1 notifies the rider of information including the direction, that is, a warning sound including information on the lane. For example, “If you enter the left lane after this point, you will be in the city center ahead of Ariake Junction and a motorcycle prohibited area”. This notification is also notified at a point of 2 km and a point of 1 km as described above.

  As described above, the navigation device 1 according to the present embodiment notifies the rider of the motorcycle 100 of information related to the entry of the motorcycle 100 into the two-passenger prohibited section on the Metropolitan Expressway. Therefore, it is possible to prevent a two-seater rider from entering a two-passenger prohibited section on the Metropolitan Expressway. In particular, even when a motorcycle rider does not know the two-passenger prohibited section, entry into the two-passer prohibited section can be easily avoided.

  In addition, the navigation device 1 changes the warning control of information related to the entry into the two-passenger prohibited section between traveling on the Metropolitan Expressway and traveling on a general road. For example, the metropolitan expressway has a higher speed limit than a general road, so the traveling speed becomes faster. In addition, the Metropolitan Expressway is restricted to interchanges at entrances, but ordinary roads do not have such restrictions. In this way, the traveling situation differs between traveling on the Metropolitan Expressway and traveling on a general road. For this reason, it is possible to safely avoid entry into a two-passenger prohibited section by outputting information on timing and contents suitable for the traveling state of the motorcycle 100 depending on the difference between traveling on the Metropolitan Expressway and traveling on a general road. be able to.

  Moreover, the navigation apparatus 1 changes the timing which outputs the information regarding the approach to the two-passenger traffic prohibition section between highway driving and general road driving. Therefore, even when traveling speed and road configuration are different, such as when driving on expressways and when traveling on ordinary roads, or when there are unique characteristics such as motorcycles, warnings for entering a two-passenger prohibited section are made without waste. And can be safely avoided. For example, it is possible to prevent unnecessary warnings such as warnings for sections where two-passengers are prohibited, even though the route is scheduled to change before the entrance to the Metropolitan Expressway while driving on general roads. Can do. Also, for example, even when trying to enter the entrance of an expressway by making a quick turn using a small turn, a warning can be given.

  Moreover, the navigation apparatus 1 outputs information at a point where the distance to the start point of the two-passenger prohibited section is 2 km while traveling on an expressway, and outputs information again at a point of 1 km. Therefore, even if the first warning is missed, it is possible to reliably avoid entering the two-passenger passage prohibited zone by listening to the second warning. In addition, by making the first warning 2 km from the starting point of the two-passenger prohibited section, it becomes the same as the guidance distance of a general navigation device, and it is easy to grasp the distance and avoid the approach Ideal for arousal. In addition, by making the second warning 1 km from the starting point of the two-passenger prohibited section, it is easy to avoid entering the two-passenger prohibited section even if the first warning is missed. Can do.

  Further, the navigation device 1 outputs information at a point where the distance to the entrance in the two-passenger prohibited section is 100 m during traveling on a general road. Therefore, for example, it is possible to prevent an unnecessary warning from being given when the vehicle does not pass by the interchange entrance in the two-passenger prohibited section due to a course change or the like. Furthermore, the navigation device 1 outputs information when a two-seater motorcycle enters a region with a radius of 100 m centering on the interchange entrance in the two-passenger prohibition section. For this reason, for example, information can be output in advance for any motorcycle that can take various approaches to the interchange entrance. Thereby, it is possible to prevent the motorcycle from entering the restricted traffic section from the general road.

  Moreover, the navigation apparatus 1 sets the range which outputs information on the basis of the start point of a branch lane, when the interchange entrance in a two-passenger prohibition area is ahead of a branch lane. Therefore, it is possible to prevent a two-seater motorcycle rider from entering the branch lane without noticing that the tip of the branch lane is a two-passenger prohibited section.

  Moreover, the navigation apparatus 1 alert | reports an interchange name as information of a two-passenger prohibition area. Therefore, it is possible to prevent the rider from mistaken the interchange exit and the interchange entrance. In addition, when there are a plurality of lanes on the Tokyo Metropolitan Expressway, the navigation device 1 outputs lane information, that is, information including direction restrictions. Therefore, it is possible to give the rider an appropriate option other than avoiding the two-passenger prohibited section. This can prevent the rider from getting off the Metropolitan Expressway unnecessarily.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above. In addition, the effects described in the embodiments of the present invention only list the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the embodiments of the present invention.

  For example, in the present embodiment, the navigation apparatus 1 having a navigation function and a warning function has been described, but the present invention is not limited to this. For example, a warning device that does not have a navigation function may be used. By using a warning device having only a warning function, it is easy to reduce the size and cost.

  Further, in the present embodiment, the description has been given using the two-passenger prohibition section of the motorcycle on the Metropolitan Expressway as the motorcycle restriction section, but the present invention is not limited to this. If the restricted section of the motorcycle is set to a section other than the two-passer-passed section of the motorcycle on the Metropolitan Expressway, information on the set location (interchange name and the destination is the restricted section of the motorcycle). The same warning control can be performed by using a certain effect. For example, when a new motorcycle traffic restriction section is set due to a law revision or the like, the same warning control can be performed by using the information.

  In this embodiment, a warning display and a warning sound are output according to the distance to the interchange at the start of the two-passenger prohibited section or the interchange entrance in the two-passenger prohibited section. It is not limited to. For example, a motorcycle information acquisition unit for a motorcycle is provided to acquire vehicle data such as the vehicle speed of the motorcycle, and from the acquired vehicle data, an interchange that starts a motorcycle two-passenger prohibited section or a motorcycle two-passenger prohibited section The time to the entrance of the interchange may be calculated, and a warning display and a warning sound may be output according to the calculated time. For example, when traveling on an expressway, the first warning may be given 5 minutes before arrival at the starting point of a motorcycle two-passenger passage prohibited section. By giving a warning 5 minutes in advance, it is possible to easily prevent the rider from entering the motorcycle two-passenger passage prohibited section. A second warning may be given 3 minutes before arrival. By performing the second warning, even if the first warning is not noticed, it is possible to easily and reliably avoid entering the two-passenger prohibited section. When traveling on a general road, a warning may be given one minute before arrival at the interchange entrance in the two-motorcycle prohibited section. A general road has a slower traveling speed than an expressway and may make a sudden change of course, but by making it one minute ahead, a warning can be reliably issued without waste.

  Moreover, in this embodiment, although the warning display and the warning sound were output according to the distance of the starting point of the two-passenger prohibition section, the present invention is not limited to this. For example, when the entrance / exit is limited as in the Metropolitan Expressway, information may be output when the exit just before the exit just before the start point of the two-passenger passage section is exceeded. If it does in this way, if information is output, what is necessary is just to get off at the next exit, and it can prevent that a rider mistakes an exit. For example, it is possible to prevent the vehicle from getting off at an exit before the exit that should be originally exited.
