  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment described below exemplifies a navigation device in order to embody the technical idea of the present invention, and is not intended to identify the present invention as this navigation device, and claims The present invention can be equally applied to the mobile communication devices of other embodiments included in the scope. For example, it may be a mobile communication device that does not have a navigation function, or may be a mobile communication device that can be removed from a vehicle and carried. FIG. 1 is a block diagram showing the configuration of the navigation device 20 of the present invention. The navigation device 20 includes a control unit 1, a display unit 2, an operation unit 3, a current position detection unit 4, a speed detection unit 5, a map information storage unit 6, a point storage unit 7, a battery 8, and a communication A section 9 and a notification section 10 are provided. As shown in FIG. 1, the control unit 1 and each unit (display unit 2 and the like) are connected by, for example, a bus, and the control unit 1 acquires the current position detected by the current position detection unit 4 and the like. Is possible.

  The control unit 1 is a control unit that comprehensively controls the entire navigation device 20. The control unit 1 includes a CPU, a ROM, and a RAM (all not shown). Various programs describing control and operation procedures are stored in the ROM. The CPU executes various programs stored in the ROM. The RAM temporarily stores data obtained during various processes and data obtained as a result of various processes. These CPU, RAM, ROM and the like are connected via a bus. Note that the CPU, ROM, and RAM may be partially or fully integrated on one chip.

  The display unit 2 is a display unit for displaying a map screen (a map image including a route to a destination, a current position of the host vehicle, a registered point stored in the point storage unit 7), and a menu screen.

  The operation unit 3 is an input operation means for a user to input a destination or operate a menu. As the operation unit 3, various keys and buttons may be provided on the navigation device body, or a touch panel function may be added to the display unit 2. Further, a remote controller for remotely operating the navigation device main body may be used as the operation unit 3.

  The current position detection unit 4 detects the current position of the host vehicle and includes a GPS receiver, a self-contained navigation means, a position calculation CPU, and the like. The self-contained navigation means includes a steering angle sensor, an acceleration sensor, a distance sensor, a direction sensor, and the like, detects the travel distance and travel direction of the own vehicle, and obtains the current position based on these values. The GPS receiver receives radio waves transmitted from a plurality of GPS satellites with a GPS antenna, performs a three-dimensional positioning process or a two-dimensional positioning process, and calculates the absolute position and direction of the own vehicle. Here, the direction is calculated based on the current vehicle position and the immediately preceding vehicle position.

  The speed detector 5 detects the moving speed of the host vehicle on which the navigation device 20 is mounted. The moving speed may be calculated from the output of the vehicle speed sensor or the acceleration sensor, or may be calculated from the difference between the travel distance between the GPS histories and the GPS reception time.

  The map information storage unit 6 stores map information that is referred to when performing route search or guidance to the destination. As the map information storage unit 6, a NAND flash, an SD memory card, or the like can be suitably used. The map information storage unit 6 may be built in the navigation device 20 or may be detachable from the navigation device 20. The map information includes information on the lane (for example, identification information for specifying the lane) and information on the side edge of the roadway. A roadway refers to a location where an automobile consisting of at least one lane (for example, a traveling lane, a climbing lane, an overtaking lane, etc.) should pass. The side edge of the roadway means a part having a space where the vehicle can be stopped off the roadway, such as a bus stop provided on one or both sides of the roadway, for example, near the top of a hill A resting place is also included at the side edge.

  Here, the map information includes road data, and the road data is composed of node data whose nodes are nodes such as the inflection points and branch points of the roads, and link data whose links are links between the nodes. Is done. The node data includes node attributes such as node number, node position coordinates (latitude / longitude), road type, information indicating intersection information, intersection name, and the like, and the number of connection links and connection link number data. .

  In addition, the link data includes the link number including the node number that is the start and end points of the link, the road type (general road, highway, side end), distance and / or required time, the road name such as the national highway ○, Consists of data on the direction of travel. In addition to the above, link data includes data such as bridges, tunnels, railroad crossings, and tollgates as link attributes.

  In the present invention, the road data includes node data / link data at the side end. Whether the current position of the own vehicle, which will be described later, is a side edge of the roadway, is determined by the control unit 1 based on the current position of the own vehicle detected by the current position detecting unit 4 and the map information. It is possible to make a determination based on whether the road type (link or node) to which the current position to which the map matching process has been performed is a side end.

  In addition to this, even if the node data / link data at the side end is not included, for example, the node data / link data constituting the roadway (general road), the node data and the link data for the location where the side end exists The road type included in may be “general roads and side edges” instead of “general roads”.

  In this case, whether or not the current position of the own vehicle, which will be described later, is a side edge of the roadway, is determined based on the current position of the own vehicle detected by the current position detecting unit 4 and the map information. It is possible to make a judgment based on whether the road type (link or node) to which the current position to which the current position has been subjected to the map matching process belongs is “general roads and side edges”. Since the vehicle may be traveling, when the control unit 1 determines that the host vehicle is parked or stopped based on the moving speed detected by the speed detection unit 5, the vehicle is a side edge of the roadway. It is preferable to determine.

  The map matching process may be performed by the control unit 1 or the current position detection unit 4. That is, based on the current position detected using a GPS receiver and / or autonomous navigation means and map information, map matching processing is performed, and the current position where map matching processing has been performed is output to the control unit 1 as the current position. Also good. Alternatively, the current position detection unit 4 including the map matching process of the control unit 1 may be used.

  The point storage unit 7 stores an arbitrary point on the map information as a registered point. For example, the side edge of a roadway such as a bus stop is stored as a registration point. In addition, a location specified by the user using the operation unit 3 to input an address or name of a place where the user frequently visits such as home or work is stored, or set as a destination when performing a route search The registered points are also stored as registered points. Furthermore, a point specified by displaying map information on the display unit 2 and designating one point on the map information by the user may be stored as a registered point. In order to simplify the description, the map information storage unit 6 and the point storage unit 7 are provided as separate configurations, but the map information storage unit 6 may include the point storage unit 7. Alternatively, the point storage unit 7 may include map information.

  The battery 8 is a power supply means when the navigation device 20 is portable, and a secondary battery such as a lithium ion battery or a nickel metal hydride battery can be suitably used. Of course, as the battery 8, a primary battery such as an alkaline manganese dry battery or a manganese dry battery may be used, or a fuel cell may be used.

  The communication unit 9 receives information transmitted from other communication devices and a transmission unit (not shown) that transmits information to other communication devices that can communicate with the navigation device 20 (hereinafter referred to as “other communication devices”). And a receiving unit (not shown). The communication method may be contactless communication such as wireless communication or infrared communication, or may be wired communication such as bus connection. Examples of other communication devices include in-vehicle devices such as navigation devices mounted on other vehicles, roadside devices such as traffic lights, and mobile communication terminals such as mobile phones possessed by pedestrians.

The alerting | reporting part 10 alert | reports various information with respect to the user of the own vehicle. The notification method is not particularly limited as long as the user can understand the contents. For example, the notification method is performed by outputting a predetermined sound via a speaker (not shown). Further, it may be performed by displaying predetermined characters or images on the display unit 2 or may be performed simultaneously with sound and display. For simplification of explanation, the notification unit 10 and the display unit 2 are provided as separate components. However, when the notification method includes display of predetermined characters or images on the display unit 2, the notification unit 10 displays the information. You may provide as a structure containing the part 2. FIG.
[First embodiment]
A first embodiment of the navigation device 20 of the present invention will be described with reference to FIG. FIG. 2 is a first flowchart showing a flow of processing executed by the control unit 1 of the navigation device 20 of the present invention.

  In step S01, the control unit 1 acquires information on the current position of the host vehicle detected by the current position detection unit 4. Next, in step S02, the control unit 1 refers to the map information stored in the map information storage unit 6 to determine whether or not the current position of the host vehicle is a side edge of the roadway. If the current position of the own vehicle is not the side edge of the roadway (N in step S02), the process returns to step S01. If the current position of the host vehicle is the side edge of the roadway (Y in step S02), the process proceeds to step S03, and the control unit 1 determines whether the host vehicle is parked or stopped. If the vehicle is not parked (N in Step S03), the process returns to Step S01.

  Further, “the own vehicle is parked or stopped” may be a state in which the moving speed of the own vehicle detected by the speed detecting unit 5 is 0 km / h, or the own vehicle is moving at a low speed due to a creep phenomenon. It is good also as including a state. Whether or not the vehicle is parked or not is not determined whether or not the engine is operating. For example, if the moving speed of the vehicle is 0 km / h even if the engine is operating. It is determined that the vehicle is parked or stopped.

  If the own vehicle is parked or stopped (Y in Step S03), the control unit 1 controls the communication unit 9 to transmit parking / stop information of the own vehicle to another communication device (Step S04).

  As parking / stopping information, for example, the other communication device that receives the parking / stopping information is only behind the host vehicle, so that the vehicle ahead is stopped in order to display it directly on the display screen of the other communication device. Please remove the vehicle ahead and proceed ahead ”or when other communication devices that have received the parking / stop information perform display processing on the display screen, It may be information including information for specifying the vehicle such as characteristics of the own vehicle and information indicating that the own vehicle is parked or stopped.

  Note that whether or not another communication device is behind the host vehicle can be detected by the method described below.

  First, position information (current position, traveling direction (direction), current traveling lane, etc.) of other communication devices (other vehicles) around the host vehicle is acquired by the communication unit 9. And the control part 1 determines whether the own vehicle and another vehicle are located on the same lane. The map information includes information about the lane (for example, identification information for identifying the lane), and two lane identification numbers are given to roads that allow two-way traffic. Based on the position information and the position information of the other vehicle, it can be determined whether or not the host vehicle and the other vehicle are located on the same lane. For example, the determination is made by comparing the position of the vehicle after the map matching with the position of the other vehicle, or comparing the road (lane) on which the map matching is performed. When the vehicle is located on the same lane, it is possible to determine whether the other communication device is behind the vehicle based on the current position of the vehicle, the traveling direction (direction), and the current position of the other communication device. Is possible.

  According to the present embodiment, the navigation device 20 (more specifically, the communication unit 9 of the navigation device 20) performs other communication when the current position of the own vehicle is the side edge of the roadway and the own vehicle is parked. The parking / stop information of the vehicle is transmitted to the device. Therefore, the other communication device that has received the parking / stop information (and / or another communication device that has received the parking / stop information via another communication device) is a mobile body (navigation device 20) around the current self. In order to notify the user who is using the other communication device that the vehicle equipped with is in a parked and stopped state, a smooth traffic state can be maintained.

[Second Embodiment]
A second embodiment of the navigation device 20 of the present invention will be described with reference to FIG. FIG. 3 is a second flowchart showing a flow of processing executed by the control unit 1 of the navigation device 20.

  In step S <b> 11, the control unit 1 acquires information on the current position of the host vehicle detected by the current position detection unit 4. Next, in step S <b> 12, the control unit 1 determines whether or not the current position of the own vehicle is within a predetermined range centered on the registered point stored in the point storage unit 7. If the current position of the host vehicle is not within a predetermined range centered on the registration point (N in step S12), the process returns to step S11. If the current position of the host vehicle is within a predetermined range centered on the registration point (Y in step S12), the control unit 1 controls the communication unit 9 to transmit parking / stop information of the host vehicle to another communication device ( Step S13). In step S12, if the predetermined range is a circle with a predetermined radius (for example, 100 m) centered on the registration point, there is no need to refer to the map information. When calculating based on the required time, for example, if the distance to the registration point (not the straight line distance but the distance to the registration point through the road) is within a range of 100 m or less, the map information is referred to. In addition, the pre-stored registration point (the side edge of the road) and the registration point arbitrarily designated by the user using the operation unit 3 (such as home) are stored together with different identifiers, so that the pre-stored It is preferable that a certain registration point and a registration point arbitrarily designated by the user can be distinguished, and the registration point used in the process of step S12 is a registration point arbitrarily designated by the user.

  It should be noted that how close the current position of the vehicle is to the registration point when transmitting and stopping information, that is, how far the predetermined range is to be set, may be within a predetermined distance range. The range may be determined according to the moving speed of the vehicle. As a method of determining the range according to the moving speed of the own vehicle, the control unit 1 calculates a distance (s) obtained by multiplying the moving speed (v) of the own vehicle by a predetermined time (t1), for example, and sets the registration point as the center. Let the range of distance (s) be a predetermined range. The predetermined time (t1) is an arbitrary time that can be determined to be immediately before arrival at the registration point, but may be set to a desired time via the operation unit 3. Further, the predetermined range is not limited to the case where the registered point is the center, and it is only necessary that the predetermined range includes the registered point.

  According to this embodiment, the navigation device 20 (more specifically, the communication unit 9 of the navigation device 20) parks the vehicle in another communication device when the current position of the vehicle is within a predetermined range including the registration point. Send stop information. Therefore, other communication devices that have received the parking / parking information (and / or other communication devices that have received the parking / parking information via another communication device) have their surrounding mobile bodies shifted to the parking / parking state. Since a user who is using another communication device is notified that he or she is going to do so, a smooth traffic state can be maintained.

  For example, when a courier company uses a navigation device mounted on a truck to search for a route with a plurality of delivery destinations that are scheduled to deliver goods as registration points, the truck has a predetermined range centered on each delivery destination. When the vehicle enters the inside (for example, 100 meters), the rear vehicle has entered the parked state in order to transmit the parking / stop information of the own vehicle to another communication device (for example, a navigation device mounted on the rear vehicle). In some cases, it is possible to prevent a situation in which the track cannot be overtaken because the cause is unknown.

[Third embodiment]
A third embodiment of the navigation device 20 of the present invention will be described with reference to FIG. FIG. 4 is a third flowchart showing the flow of processing executed by the control unit 1 of the navigation device 20.

  In step S <b> 21, the control unit 1 acquires information related to the current position of the host vehicle detected by the current position detection unit 4. Next, in step S <b> 22, the control unit 1 determines whether or not the current position of the own vehicle is within a predetermined range centered on the registered point stored in the point storage unit 7. If the current position of the host vehicle is not within a predetermined range centered on the registration point (N in step S22), the process returns to step S21. If the current position of the host vehicle is within a predetermined range centered on the registration point (Y in step S22), the process proceeds to step S23, and the control unit 1 determines whether the host vehicle is parked or stopped. If the own vehicle is not parked (N in Step S23), the process returns to Step S21. If the own vehicle is parked or stopped (Y in step S23), the control unit 1 controls the communication unit 9 to transmit parking / stop information of the own vehicle to another communication device (step S24).

In step S22, when the point storage unit 7 also stores map information, a node whose road type is included in the map information is a registered point, and a range between the nodes is a predetermined range.
The determination whether the current position shown in the first embodiment is a side end is also included. When a predetermined range is defined between the nodes, the predetermined range is more precisely two or more nodes whose road types are side ends and links whose road types connecting these nodes are side ends.

  According to the present embodiment, the navigation device 20 (more specifically, the navigation device) when the current position of the vehicle is parked and stopped within a predetermined range including the registration point and the vehicle is parked. The communication unit 9) 20 transmits the parking / stop information of the vehicle to another communication device. Therefore, other communication devices that have received the parking / stopping information (and / or other communication devices that have received the parking / stopping information via another communication device) are in a state where the current mobile object is parked Since this is notified to the user who is using another communication apparatus, a smooth traffic state can be maintained.

  For example, even if the position of the home is stored as a registered point in the navigation device mounted on the vehicle, the route search for returning to the home (route search using the home as the destination) is not performed if the user frequently passes the route. It is possible. On the other hand, if the parking space faces the road, it may be necessary to park in the back directly from the road, and if there is a rear vehicle at that time, the rear vehicle will go first It is conceivable that the vehicle will be parked or stopped. In such a case, since the parking / stop information of the own vehicle is transmitted to another communication device (for example, a navigation device mounted on the vehicle behind the vehicle), the vehicle behind the vehicle is unknown because the cause of the vehicle parked / stopped is unknown. It is possible to prevent the occurrence of a situation in which it cannot be overtaken.

[Fourth embodiment]
4th Embodiment of the navigation apparatus 20 of this invention is described using FIG. FIG. 5 is a fourth flowchart showing a flow of processing executed by the control unit 1 of the navigation device 20.

  In step S <b> 31, the control unit 1 acquires information on the current position of the host vehicle detected by the current position detection unit 4. Next, in step S <b> 32, the control unit 1 determines whether or not the current position of the own vehicle is within a predetermined range centered on the registered point stored in the point storage unit 7. If the current position of the own vehicle is not within the predetermined range centered on the registration point (N in step S32), the process proceeds to step S33, and if the current position of the own vehicle is within the predetermined range centered on the registration point (step S32). Y) Proceed to step S34. In step S <b> 33, the control unit 1 refers to the map information stored in the map information storage unit 6 and determines whether or not the current position of the host vehicle is a side edge of the roadway. If the current position of the own vehicle is not the side edge of the roadway (N in step S33), the process returns to step S31. If the current position of the host vehicle is the side edge of the roadway (Y in step S33), the process proceeds to step S34.

  In the present embodiment, it is determined whether or not the current position of the own vehicle is within a predetermined range as a registration point (step S32), and whether or not the current position of the own vehicle is a side edge of the roadway (step S32). Although it is performed before S33), it may be determined whether or not the current position of the host vehicle is on the side edge of the roadway, or two processes may be performed simultaneously. That is, if at least one of the two determination processes is satisfied, the process proceeds to step S34. If both the determination processes are not satisfied, the process returns to step S31. Further, as described above, the predetermined range may be set as the side edge (node / link) of the roadway as one process without performing the processes of step S32 and step S33 separately.

  In step S34, the control unit 1 determines whether or not the host vehicle is parked or stopped. If the own vehicle is not parked (N in Step S34), the process returns to Step S31. If the own vehicle is parked or stopped (Y in step S34), the process proceeds to step S35. In step S35, the control unit 1 acquires the parking / stopping time (T) of the host vehicle, and determines whether the parking / stopping time (T) exceeds a predetermined time (t2). If the parking and stopping time (T) of the own vehicle does not exceed the predetermined time (t2), the process returns to step S31. If the parking / stopping time (T) of the own vehicle exceeds the predetermined time (t2), the control unit 1 controls the communication unit 9 to transmit the parking / stopping information of the own vehicle to another communication device (step S36). .

  The parking / stopping time (T) of the host vehicle can be obtained by, for example, storing the time when the host vehicle started parking / stopping, and calculating and storing the stored time and the current time. Moreover, it is good also as making a timer (not shown) etc. measure parking / stopping time and acquiring the result. The predetermined time (t2) is an arbitrary time during which it can be determined that the host vehicle is in the parked / stopped state, but may be set to a desired time via the operation unit 3.

  According to the present embodiment, the same effects as those of the first to third embodiments can be obtained. In addition, since parking / stop information is not transmitted unless the parking / parking time exceeds a predetermined time, parking / parking information is excessively transmitted when the vehicle is started immediately, such as when the parking / parking position is wrong. There is nothing.

[Fifth Embodiment]
5th Embodiment of the navigation apparatus 20 of this invention is described using FIG. FIG. 6 is a fifth flowchart showing a flow of processing executed by the control unit 1 of the navigation device 20. Note that steps S41 to S46 in FIG. 6 are the same as steps S31 to S36 in FIG. In step S47, the control unit 1 controls the notification unit 10 to notify the user that the parking / stop information of the own vehicle has been transmitted to another communication device.

  According to this embodiment, in order to notify the user that the parking / stop information of the own vehicle has been transmitted to another communication device, the user uses another communication device around the own vehicle (more specifically, using another communication device). A user or a vehicle equipped with another communication device) can be predicted (for example, a rear vehicle pulls out the vehicle and tries to come out before), and a driving action can be determined based on the behavior. (E.g., start after the vehicle behind the vehicle has pulled out)

[Sixth Embodiment]
In the present embodiment, the control unit 1 controls the notification unit 10 when the communication unit 9 receives the parking / stopping information of another vehicle in the information received from the other communication device, and displays the parking / stopping information of the other vehicle. Inform. The notification content may be notification of parking / stop information of another vehicle received from another communication device as it is, or the content to be notified by the control unit 1 may be determined based on the parking / stop information.

  For example, if the received parking / stop information includes at least the current position of another communication device (may be the current position after the map matching process), the current position of the vehicle after the map matching and other By comparing the current position of the communication device or by comparing the road (lane) on which map matching has been performed, it can be determined whether the vehicle is on the same lane, so other communication devices are on the same lane as the vehicle. You may alert | report only when it is located.

Further, when another communication device is located on the same lane as the own vehicle, the other communication device is automatically determined based on the current position of the own vehicle, the traveling direction (direction), and the current position of the other communication device. It is judged whether it is ahead of the car, and only when it is ahead "Please pull out and advance ahead because the vehicle ahead will stop."
Such a message may be displayed and / or output by voice.

  According to this embodiment, since the parking / stopping state of other vehicles is notified, a smooth traffic state can be maintained.

  In addition, when not only the said embodiment but the communication part 9 has received information (current position, parking / stop information, etc.) from another communication apparatus, another communication apparatus is in the range which the communication part 9 can communicate. The control part 1 may control not to transmit parking / stop information as not existing.

  The present invention can be used in a mobile communication device that transmits parking / stop information.
