Therefore, information required by the operator is input to the control unit 3 according to the operation states of the voice input unit 5 and the switch unit 6.

FIG. 2 is a flowchart of the intersection information creation processing performed by the control unit 3 of the navigation device according to the first embodiment of the present invention. FIGS. 3A and 3B are views showing an example of an intersection information display of the navigation device according to the first embodiment of the present invention, wherein FIG. 3A shows an example of split display and FIG. 3B shows an example of screen switching display. Hereinafter, description will be made with reference to the drawings. In this embodiment, the regulation / congestion information obtained in the traveling direction of the vehicle and the detailed information at the intersection in front of the regulation / congestion point are linked and output at a necessary timing. This process is performed during the traveling guidance by the navigation device.

In step S11, position information of the own vehicle is obtained, and regulation / congestion information is obtained, and the process proceeds to step S12. In other words, the position of the vehicle is detected by the GPS receiver 11, and the position of the vehicle is specified on the map by comparing it with the map database 12. If the position of the own vehicle cannot be detected by the GPS receiver 11 in a tunnel or the like, the output is supplemented by the output of an attached gyro sensor, vehicle speed sensor, or the like. FM broadcasting station (wide area) by VICS receiver 21 and beacon receiver 22
And traffic information such as regulations and traffic jams transmitted from the passing intersection. In step S12, it is determined whether or not there is regulation / congestion information. If there is regulation / congestion information, the process proceeds to step S13. If there is no regulation / congestion information, the process returns to step S11 to acquire own vehicle position information, Continue acquiring traffic jam information. The PLL circuit outputs a signal of a difference frequency so that a signal of a predetermined intermediate frequency is obtained so that the receiving circuit can receive desired traffic information. Then, it is determined whether or not there is an FM broadcast wave having a predetermined reception level or higher, and it is determined whether or not a broadcast wave of a receivable frequency includes a code corresponding to traffic information specified in advance. .
The received traffic information is converted into characters and the like by a decoder. In the beacon receiver 22, the same regulation and
Judgment is made based on whether or not the traffic congestion information has been transmitted and the information has been successfully received.

In step S13, the distance from the vehicle position to the intersection just before the regulation / congestion section is calculated, and the flow advances to step S14. In other words, the position of the vehicle acquired by the GPS receiver 11 and the intersection (the regulation / congestion point in FIG. 3A) in front of the regulation / congestion point (the last position) acquired by the VICS receiver 21 and the beacon receiver 22. (The intersection having the detailed information closest to (the tail end) is set as the target intersection). In the present embodiment, the target intersection is an intersection with the nearest intersection information to the regulation / congestion point, but is not limited to this.
All intersections on the guide route or in the traveling direction having the intersection information before the regulation / congestion point may be used. In step S14, it is determined whether or not it is the output timing. If the output timing, the process proceeds to step S15. If not, the process returns to step S11. The output timing is a timing necessary for the driver to take appropriate measures in response to the regulation / congestion information (taking a detour route to avoid congestion, etc.), and from the position of the own vehicle (current location) to just before the regulation / congestion point. For example, when the vehicle is traveling at a speed of 50 km / h, one minute before the scheduled arrival time at the intersection to take measures such as detours, the traffic information and traffic information are determined by the time required to reach the intersection (required time). If the intersection information is required, the output timing is based on the speed at this time when the vehicle arrives at about 800 m before (or less than or equal to) the intersection. Until the output timing, the control / congestion information and the intersection information are not output, and the route guidance map of the navigation device is displayed to guide the vehicle.

In step S15, it is determined whether or not information (regulation / congestion information or intersection information) has not been output. If the information has not been output, the process proceeds to step S16. If the information has not been output, the process proceeds to step S20. Move on to That is, it is determined whether necessary regulation / congestion information or intersection information has already been output in the past. In step S16, it is determined whether or not guidance is being provided along the set route. If guidance is being provided, the process proceeds to step S17. If not, control is passed to step S19. In other words, the departure point,
It is determined whether the vehicle is traveling on the route set by inputting the destination, in particular, whether the vehicle is traveling without setting the route, and this determination is determined by the presence or absence of the route setting operation by the user. This determination is for determining to which range the intersection to be output is limited.

In step S17, detailed information of the intersection consisting of the image data in front of the regulated / congested road on the route is obtained, and the detailed information is taken from the VICS receiver 21 or the like to obtain the regulated / congested information and the distance to the target intersection. The output information is created by combining the images indicating the information, and the process proceeds to step S18.
Since the vehicle is traveling on a preset route, the intersection (intersection just before the point of the regulation / congestion information) on this route is described in a CD-ROM or the like (map database 1).
2) From the detailed information of the intersection (intersection name, intersection mark,
Intersection map, lane map, road map, etc.). The output information includes the distance to the intersection just before the regulation / congestion on the guide route, the classification of the regulation / congestion, the road lane diagram where the traffic is regulated, the regulation / congestion point (point), the location before the regulation / congestion point It is an intersection map (including a mark such as a building).

In step S18, the output information is drawn and output as audio, and the process returns to step S11. That is, output information (congestion information and intersection information) is displayed on the display unit 41 as shown in FIG. The display method includes a method of displaying the creation information screen on the already displayed route guidance map screen on-screen, and a method of dividing the display screen into two and displaying both the route guidance map and the creation information screen side by side (FIG. 3 (a)), a method of displaying the creation information screen in a balloon on the already displayed route guidance map screen, and a method of switching between the already displayed route guidance map screen and the creation information screen for display (FIG. 3 ( b)). Further, the guidance voice is synthesized and output, for example, "800 m to the intersection just before the traffic jam". In this case, the detailed information of the target intersection is displayed in the image, but the name of the intersection, the distance from the own vehicle position, the recommended lane, the right / left turn direction, the intersection mark (building, etc.), the intersection A nearby road condition, traffic regulation, or the like may be output.

In step S19, detailed information of the intersection consisting of image data in front of the regulation / congestion road on the traveling road (traveling direction) is acquired, and the regulation / congestion information taken from the VICS receiver 21 or the like is included in the detailed information. The output information is created by synthesizing the image indicating the distance information to the target intersection, and the process proceeds to step S18. Since the vehicle is traveling without setting a route, information on a wide range of regulations and traffic congestion in the traveling direction is acquired, and the traveling direction (the type of the traveling road, for example, on the extension of a prefectural road or within a predetermined azimuth angle) ) Is the intersection to be output. The method for creating the output information is substantially the same as the method for creating the output information in step S17, and thus the description is omitted.

In step S20, it is determined whether or not the information has been updated. If the information has been updated, the process proceeds to step S21, and if not, the process returns to step S11. That is, it is determined whether there is a change in the outputted regulation / congestion information or intersection information. For example, it is determined whether there is a change in regulation / congestion state, a change in the distance to the intersection, or the like. In step S21, output information is re-created, and the routine goes to step S18. That is, the latest regulation / congestion information and intersection information are recreated. The contents and method of creating the information are the same as those in steps S17 and S19.

As described above, in the embodiment of the present invention, the regulation information and the traffic congestion information in the traveling direction of the vehicle are displayed on the display screen at an appropriate timing in conjunction with the intersection information of the navigation device, or output by voice. it can. As a result, if necessary, a route change such as a detour can be made earlier.

FIG. 6 is a diagram showing an example of an intersection selection based on an intersection list of the navigation device according to the second embodiment of the present invention. FIG. 7 is a diagram showing an example of selecting an intersection on a map by the navigation device according to the second embodiment of the present invention, wherein FIG.

FIG. 8 is a flowchart of intersection information creation processing (modification) performed by the control unit 3 of the navigation device according to the second embodiment of the present invention. Hereinafter, description will be made with reference to the drawings.
The intersection information according to the present embodiment is for displaying detailed information at the intersection selected by the driver's operation, and for allowing the driver to take a smooth response at the intersection, and is not necessarily limited to regulation / congestion. No need to link to information. Further, the configuration of the device according to the present embodiment is the same as that of the first embodiment, and thus the description is omitted.

In step S31, the position information of the own vehicle is obtained, and the routine goes to step S32. That is, the GPS receiver 1
1, the vehicle position is detected, and the current position is specified on a map by comparing it with the map database 12. In step S32, it is determined whether or not guidance is being provided along the set route. If guidance is being provided along the route, the process proceeds to step S33. If not, guidance is provided to step S39. In other words, it is determined whether the vehicle is traveling on the travel route set (searched) by inputting the departure place and the destination in advance by the navigation device, and in particular, whether the vehicle is traveling without setting the route. Is determined by the presence or absence of a route setting operation by the user.

In step S33, it is determined whether or not the on-route intersection list has been created. If the on-route intersection list has been created, the process proceeds to step S35. If the on-route intersection list has not been created, the process proceeds to step S34. . Since the vehicle is traveling on a preset route, it is determined whether or not a list relating to the intersections on this route has been created. The intersection on the guidance route is an intersection on the guidance route set as shown in FIG. 5 (a), in which the driver should pay particular attention to a right turn or a left turn, that is, to guide the driver. . In step S34, an intersection list is created, and the process proceeds to step S35. That is, an intersection (in this case, an intersection to be turned right or left) on the travel guide route of the vehicle is read from the detailed information of the intersection such as a CD-ROM or the like (the map database 12) so that the user can select the intersection. A list including intersection names such as 6 is created.

In step S35, it is determined whether or not a list request has been made. If there is a list request, the process proceeds to step S36. If there is no list request, the process returns to step S31. This is for requesting the intersection list when the user selects an intersection, and the operation state of a predetermined operation switch 6a (for example, the operation switch 6a which is not shown but is displayed as "intersection list" among the operation switches 6a is pressed) Etc.). In addition, "intersection list" may be input by other voice. In step S36, an intersection list is displayed, and the routine goes to step S37. That is, an intersection list as shown in FIG. 6 is displayed on the screen of the display unit 41 so that the user can select an intersection. This intersection is limited to an intersection having detailed information.

In step S37, it is determined whether or not an intersection has been selected.
And waits if no intersection is selected. That is,
It waits for the user to select a desired intersection from the intersection list displayed on the display unit 41. This is an intersection created in advance (an intersection on the guide route in step S34 and an intersection on the traveling road and in the display map in step S40).
A list of names is displayed as shown in FIG. 6, and the driver is asked to select a desired intersection by pressing an operation switch 6a, a joystick 6b, a remote control key, or the like arranged corresponding to the intersection name. There is also a method in which a driver inputs a desired intersection name (or a corresponding number) by voice to the displayed intersection list, performs voice recognition in the voice input unit 5, and inputs the recognized name to the control unit 3.

In step S38, intersection information is created, drawn or output as audio, and the process returns to step S31. That is, detailed information on the selected intersection is displayed on the display unit 41 as shown in FIG. 3 or is synthesized and output (in this case, unlike the first embodiment, traffic congestion information and the like are reflected). Is not.) The display method includes a method of displaying the creation information screen on the already displayed route guidance map screen on-screen, a method of dividing the display screen into two and displaying both the route guidance map and the creation information screen side by side, A method for displaying the creation information screen in a balloon on the displayed route guidance map screen, and a method for switching between the already displayed route guidance map screen and the creation information screen for display (FIG. 3)
(B)). Further, the guidance voice at the target intersection is synthesized and output.

In step S39, it is determined whether or not the intersection list on the traveling road and in the display screen has been created. If the list has been created, the process proceeds to step S35, and if not, the process proceeds to step S40. Since the vehicle is not traveling on a preset route, it is determined whether or not a list regarding intersections on the traveling road and in the display screen has been created. As shown in FIG. 5B, the intersections on the traveling road are all intersections having intersection information on the traveling road (FIG.
(B) indicates the target intersection). Also, the intersections in the display screen are all intersections having intersection information on the screen displayed at the current scale as shown in FIG. In step S40, a list is created, and the process proceeds to step S35. That is, an intersection on the road on which the vehicle runs and on the display screen is read from detailed information on the intersection such as a CD-ROM (map database 12) so that the user can select the intersection, and a list including the names of the intersections is created.

In this embodiment, an intersection list is created in advance as an intersection selection method, and the intersections in the list are selected by the driver. In addition to this method, an intersection is selected from the list. There is also a method of directly designating the intersection displayed on the map screen of the navigation device without using it. As a method of directly designating the target intersection, a mark such as a star mark is attached to all intersections having detailed information of the intersection (detailed information is recorded on the CD-ROM) within the range of the screen displayed by the navigation. The user touches a mark such as an asterisk of a desired intersection with his / her finger (touch panel) (see FIG. 7 (a)), and a cursor is directly determined on the desired intersection using a joystick. There is a method of pressing a button (see FIG. 7B) and the like. Further, there is a method in which a desired intersection name is directly uttered, the intersection name is voice-recognized by the voice input unit 5 and input to the control unit 3.

As the output timing of the intersection information, the intersection information is displayed (output) when the user selects the intersection, or, as in the first embodiment, the state in which the route guidance screen remains even if the intersection is selected. It is also possible to display (output) when the vehicle reaches a predetermined distance before the selected intersection. FIG. 8 shows an example in which such direct designation processing and output timing processing by the user are added.

The same processing steps as those in the flowchart of FIG. 4 are denoted by the same step numbers, and description thereof is omitted. In step S41, it is determined whether or not there is a user input. If there is a user input, the process proceeds to step S35. If there is no user input, the process returns to step S31. The user input is a list request or an intersection information request, and is used to determine the presence or absence of these requests. In step S42, output information of the target intersection is created, and the process proceeds to step S43. That is, since there is no list request in step S35, instead of selecting an intersection from the intersection list,
Since the intersection at which the intersection information is to be displayed (output) is directly specified by the user, information on the intersection is created.

In step S43, it is determined whether or not there is a timing setting.
Go to step 44, if there is no timing setting, step S38
Move on to The timing is to determine whether to output the intersection information desired by the user immediately (when there is a user input) or when the vehicle reaches a point a predetermined distance before the intersection. In step S44, the timing distance is calculated from the distance from the own vehicle position and the vehicle speed, and the process proceeds to step S45. That is, it calculates how far before the intersection the user wants the intersection information to change lanes or the like. If the output timing is too early, the navigation route guidance screen becomes difficult to see (or cannot be seen when the screen is switched). In step S45, it is determined whether or not it is the output timing. If the output timing, the process proceeds to step S38. If not, the process returns to step S44 and waits until the output timing.

The detailed information of the intersection described above is stored in advance on a CD.
-Although stored in a ROM, a DVD, or the like, the present invention is not limited to this, and the detailed information may be loaded into a hard disk via an external network and updated.

As described above, in the embodiment of the present invention, information about the intersection in the traveling direction, such as the right or left turn direction, the traveling lane state, and the landmarks, can be acquired in advance, so that there is no panic just before the intersection. You can concentrate on driving.
