Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a traffic information notification method, a traffic information notification device, and a storage medium, and in particular, receives traffic information data such as VICS (Vehicle Information and Communication System) and ATIS (Advanced Traffic Information Service). The present invention relates to a traffic information notification method, a traffic information notification device that executes the traffic information notification method, and a storage medium that stores a program that realizes the traffic information notification method.
[0002]
[Prior art]
In recent years, in order to improve road traffic conditions, by notifying vehicle drivers of traffic information such as traffic jams, accidents, or parking space availability, drivers can select appropriate routes to prevent strays and misruns. Environmental problems such as exhaust gas are promoted by smoothing traffic flow or by distributing traffic flow.
[0003]
As such a system, there are traffic information data services such as VICS, ATIS, etc., and FM multiplex broadcasting by FM stations, light and radio wave beacon devices installed on the road, or mobile phone devices are being used while traveling. There are systems that send traffic information to vehicles.
[0004]
On the vehicle side that has received this traffic information, the road map displayed on the display device of the navigation system, the display color of the road or parking lot displayed as a component of the road map, the color of the name, or these The color of an arrow or the like formed in the vicinity of the vehicle is changed according to the received traffic information to notify the driver of a traffic jam or a parking lot empty state.
[0005]
The transmitted traffic information is 10 km square for optical beacons, 100 km for expressways for radio beacons, and a wide range of traffic information for each prefecture or a plurality of prefectures for FM multiplex broadcasting.
On the vehicle side, all of these data are accumulated while being updated each time transmission is made, and the road, parking area, service area, parking lot, etc. currently displayed on the display device in the data (hereinafter referred to as the following) If the traffic information corresponding to “point” is present, the color of the point itself, the name of the point or the symbol or figure displayed in the vicinity is changed, and the content of the traffic information is changed to the driver by the change of the color. I was reporting.
[0006]
For example, in the case of a road, the color of the lane in the corresponding direction or the color of the arrow indicating the direction drawn along the road is “red” if the traffic is congested, “orange” if it is congested. The driver is informed by displaying “blue” if the traffic is flowing, and “black” when the traffic is closed.
[0007]
By checking this color, the driver can grasp the traffic condition of the road he is trying to pass, so he can drive while avoiding traffic congestion and congestion.
[0008]
[Problems to be solved by the invention]
However, the received traffic information is all stored in the reception buffer while being sequentially updated each time transmission is made, but this traffic information is only displayed in conjunction with the map. Therefore, if the driver wants to know traffic information of a specific point such as a road that passes through or a frequently used parking lot, the driver will not be displayed on the display device of the navigation system unless he / she is close to it. Only when the display of the point appears on the display device of the navigation system may the traffic color be known to be congested or full.
[0009]
In such a case, you will be looking for another route or parking lot near that point, which may lead to strays or miscarriages, and the traffic information at the corners is not useful enough was there.
By moving the map display of the navigation system to a target point by a driver's manual operation, it is possible to check the traffic state at that point in advance even if the vehicle is away from that point. However, the traffic condition of the point changes every moment, and the contents of the traffic information from FM stations etc. change every moment reflecting it. Even if there is no problem in the content of the traffic information, there is a possibility that the traffic information changes during driving, resulting in a traffic jam or a full vehicle condition. However, frequent checks during traveling are problematic in terms of safe driving. If the vehicle is stopped many times, the driving efficiency becomes very poor and there is no guarantee that there will be a place to stop.
[0010]
An object of the present invention is to solve such problems, to grasp the contents of traffic information at a desired point or changes thereof at an early stage, and to contribute to the realization of a smooth traffic flow.
[0011]

DETAILED DESCRIPTION OF THE INVENTION
[Embodiment 1]
FIG. 1 is a block diagram showing the overall configuration of an in-vehicle map display device 2 as Embodiment 1 of the present invention. The on-vehicle map display device 2 includes a position detector 4, a map data input device 6, an operation switch group 8, a control circuit 10 connected thereto, an external memory 12 connected to the control circuit 10, a display device 14 and a remote controller. A sensor 15 is provided. The control circuit 10 is configured as a normal computer, and includes a CPU, a ROM, a RAM, an I / O, and a bus line for connecting these configurations.
[0036]
The position detector 4 includes a well-known geomagnetic sensor 16, a gyroscope 18, a distance sensor 20, and a GPS receiver 22 for GPS (Global Positioning System) that detects the position of the vehicle based on radio waves from a satellite. Yes. Since these sensors 16, 18, 20, and 22 have errors of different properties, they are configured to be used while being interpolated by a plurality of sensors. Depending on the accuracy, a part of the above may be used, and further, a steering rotation sensor, a wheel sensor of each rolling wheel, or the like may be used.
[0037]
The map data input device 6 is a device for inputting various data including so-called map matching data for improving the accuracy of position detection, map data, and landmark data described later. As a medium, a CD-ROM is generally used because of the amount of data, but another medium such as a memory card may be used.
[0038]
The vehicle-mounted map display device 2 is configured as a so-called navigation system by the position detector 4, the map data input device 6, the operation switch group 8, the control circuit 10, the display device 14, and the like. The display device 14 is a color display device. On the screen of the display device 14, the vehicle current position mark input from the position detector 4, the map data input from the map data input device 6, and further displayed on the map. Additional data such as guidance routes to be set and landmarks of setting points to be described later can be displayed in an overlapping manner.
[0039]
In addition, when the in-vehicle map display device 2 inputs the position of the destination from the remote control sensor 15 or the operation switch group 8 via a remote control terminal (hereinafter referred to as a remote controller) 15a, the object position is detected from the current position. It also has a so-called route guidance function that automatically selects the optimum route to the ground and forms and displays a guidance route. As a method for automatically setting an optimal route, a method such as the Dijkstra method is known. For example, a touch switch or a mechanical switch integrated with the display device 14 is used as the operation switch group 8 and is used for various inputs.
[0040]
Further, the on-vehicle map display device 2 includes a VICS receiver 24. This VICS receiver 24 includes receivers for FM multiplex broadcasting, radio wave beacons, and optical beacons, and is digitally transmitted from FM stations in each region, radio beacon transmitters on expressways, and optical beacon transmitters on general roads. Receive traffic information in the form. The received traffic information is written as digital data in a reception buffer set in a part of a RAM provided in the control circuit 10. Hereinafter, traffic information transmitted by FM multiplex broadcasting from an FM station will be described as an example, but traffic information transmitted to a vehicle side by a radio beacon or an optical beacon at a specific point on the road is also handled in the same manner. .
[0041]
The traffic information transmitted by FM multiplex broadcasting transmits traffic information of roads and parking lots in a wide area extending across prefectures or a plurality of prefectures. For example, the transmission of traffic information such as a highway, a general road, a parking lot, etc. in the area that the FM station is in charge of is repeatedly performed at a rate of once every 2.5 minutes. Therefore, the contents of the reception buffer of the control circuit 10 are rewritten every 2.5 minutes. In the case of a radio wave beacon and an optical beacon, the reception buffer is rewritten when a vehicle enters the reception area.
[0042]
This traffic information includes information on traffic congestion such as traffic congestion points and traffic congestion sections, time required information between major points, traffic obstacle information such as accidents, broken cars, roadside obstacles, construction and work, traffic closures, speed restrictions, and lane restrictions. Traffic regulation information including temporary regulations such as the cause and the cause thereof, and parking lot information for informing the availability of parking lots / service areas / parking areas.
[0043]
Based on the received traffic information, the control circuit 10 performs a process of displaying traffic information of a point such as a road or a parking lot set by the driver described later on the display device 14. This display is performed as a display separate from the display of the road map and the guide route as the navigation system.
[0044]
Further, as a process of the navigation system, the control circuit 10 can be operated similarly by the driver from the menu displayed on the display device 14 after the vehicle-mounted map display device 2 is turned on, using the remote control 15a (operation switch group 8 as well. When the route information display process is selected in order to display the guidance route on the display device 14, the following processing is performed.
[0045]
That is, when the driver inputs the destination based on the map on the display device 14, the current location of the vehicle is obtained based on the satellite data obtained from the GPS receiver 22, and the Dijkstra method is used between the destination and the current location. A process of calculating the cost and obtaining the shortest route from the current location to the destination as the guidance route is performed. Then, the guidance route is displayed on the road map on the display device 14 to guide the driver of the appropriate route. Such calculation processing and guidance processing for obtaining a guidance route are generally well-known processing, and thus description thereof is omitted.
[0046]
In addition, when the VICS indicator display process is selected in order to display the traffic information of a desired point of the driver on the display device 14 by selecting the remote controller 15a from the menu displayed on the display device 14, FIGS. The process shown in the flowchart is performed.
[0047]
When the process is started, first, a VICS setting menu is displayed (S100). The VICS setting menu screen 50 is shown in FIG. In the title line 50a, “VICS designated point traffic situation” is displayed, and below that, a VICS setting menu is displayed. The contents of the VICS setting menu are displayed as a list display item 52, a point registration item 54, a point correction item 56, a point deletion item 58, a point name change item 60, and a map display ON item 62. It is composed of On the right side of the VICS setting menu, a return key 64 for returning to the previous screen and a current position key 66 for displaying a map of the current position are displayed.
[0048]
First, a case will be described in which the direction key of the remote controller 15a is operated to instruct the point registration item 54 in the VICS setting menu and the enter key is input on the remote controller 15a. The fact that the point registration item 54 has been instructed can be determined by the fact that the display of only the point registration item 54 is brightened on the screen 50, so that it is determined by pressing the determination key of the remote controller 15a in that state.
[0049]
After step S100, the process waits for key input (S110), and the VICS setting menu item designated when the enter key is pressed, here, point registration processing is executed.
First, since a list of points to be set, that is, a point list can be registered here, three points are displayed as a list (S120). The point list display screen 70 is shown in FIG. In the title row 70a, "point registration" is displayed, and below it, three registration point fields 72, 74, and 76 are arranged.
[0050]
Among these points, point A is not registered and the name associated with the corresponding point is not displayed. However, for point B, the point “East to Shibuya Ward Dogenzaka” on “△△△ Street” Since the point is registered, “Shibuya-ku, near Togenzaka Tokyu” is displayed as a simplified display. As for point C, the point of “Southbound near Sakuragicho, Nishi-ku, Yokohama” on “National Route XX” is registered as a point, so “Southbound near Sakuragicho, Nishi-ku, Yokohama” is displayed as a simplified display. .
[0051]
Next, it waits for key input (S130). If the registration point field 72 of point A is designated by the direction key of the remote controller 15a and the enter key is pressed, the registration point field 72 of point A is selected and then displayed. The screen 70 disappears and a map is displayed on the display device 14 (S140). Next, it waits for key input (S150). At this time, the displayed map can be switched in several steps from a wide area such as a national map to a detailed map displaying each road and facility by operating the remote controller 15a (corresponding to “change display point” in S150). The display position can be moved by scrolling.
[0052]
By performing such an operation on the map, matching the desired point with the cursor on the display device 14 and pressing the enter key, the desired point is selected as a point to be registered as a point A. Therefore, the registration of the selected point is performed for the point A (S160). In the case of road registration, since the input of the road direction is requested after the determination key is pressed, the road direction is registered after the driver determines the road direction. If there is no road / facility that matches the cursor, the road / facility closest to the cursor position is registered.
[0053]
For example, if the road direction is registered as “north bound” at “Near Shiba Park in Minato Ward” on “□□□ Street”, the process returns to step S120 after registration, and as shown in FIG. "Regarding Shiba Park near Kitayuki" is displayed and clearly indicated. The registration corresponds to the point A in the VICS indicator storage area in which the link number (number specifying the road or parking lot) and the place name are set in the RAM for each of the points A, B, and C. This is done by storing in the area.
[0054]
Also, at this time, if traffic information of “Nishi-ku near Minato-ku Shiba Park” on “□□□ Street” is received from the VICS receiver 24 and exists in the reception buffer, traffic congestion will occur at the same time on the right side of point A A car figure 72c representing the state of is displayed. In the example of FIG. 9, since the figure 72c of three cars is displayed, it indicates that there is a traffic jam. If there is no traffic information, the car graphic 72c is not displayed.
[0055]
In addition, about the other point B, the figure 74c of a motor vehicle is two, and represents the state which is beginning to be crowded, and about the point C, the figure 76c of a motor vehicle is one, and the traffic flow is flowing smoothly. Indicates the state.
Next, to end point registration, the VICS setting menu shown in FIG. 7 (S100) is displayed by pointing the return key 64 on the display screen 70 and pressing the enter key (corresponding to “cancel” in S130). Return to).
[0056]
As described above, when at least one point is registered in the point list, the setting point traffic information extraction process shown in FIG. 6 is interrupted and executed every predetermined time, here, every minute.
That is, from the traffic information received by the VICS receiver 24 and stored in the reception buffer, the traffic information of one point is read into the work area of the RAM (S600), and the traffic information is the traffic information of the set point, That is, it is determined whether or not the traffic information is a point registered in the point list (S610). The traffic information received from the VICS receiver 24 is a record of the link number, place name, traffic state, etc., and sends traffic information for all points in the corresponding area. It is determined whether or not it is traffic information regarding a point set by itself.
[0057]
If the traffic information corresponds to the set point (“YES” in S610), the traffic information and the like are stored in the RAM for each of the points A, B, and C described above in the RAM. The area is stored in the corresponding area (S620).
[0058]
Next, it is determined whether or not all the data in the reception buffer has been determined in step S610 (S630). The process of step S630 is also executed when it is determined that the read traffic information is not the traffic information of the set point (“NO” in S610).
[0059]
If unprocessed data exists (“NO” in S630), the process returns to step S600 again. If there is no unprocessed data (“YES” in S630), the set point traffic information extraction process is terminated. In this way, the data at the set point is stored separately from the reception buffer, and the content is updated every minute.
[0060]
Therefore, the number of the automobile figures 72c, 74c, and 76c shown in FIGS. 8 and 9 and the color displayed by the indicator 86 shown in FIGS. 12 and 13 to be described later reflect the contents of the traffic information. Therefore, it is updated every minute by the set point traffic information extraction process. For this reason, the driver can grasp the traffic state at a desired point in real time.
When “list display” is selected on the screen 50 in FIG. 7, a point list display screen 78 shown in FIG. 10 is displayed on the display device 14 (S200). The title line 78a is displayed as “congestion monitor”. The other parts are the same as in FIG. Since the display screen 78 displays the traffic information of the set point extracted by the set point traffic information extraction process shown in FIG. 6, the latest traffic information is always displayed. For this reason, the driver can easily obtain the latest traffic information of the point set by himself / herself by selecting this display after registering the points.
[0061]
When a desired point is selected from points A, B, and C in this point list (corresponding to “selection” in S210), a map around that point is displayed centering on the point registered in the point list. It is displayed on the device 14 (S220). As a result, the driver can grasp the traffic conditions in the vicinity of the point set by the driver. The map display area can also be changed by operating the remote controller 15a (corresponding to “change display point” in S230).
[0062]
When the return key 64 is instructed by the remote controller 15a and the enter key is pressed to instruct the display end (corresponding to “display end” in S230), the display returns to the point list shown in FIG. 10 again (S200). If no further list display is performed, the return key 64 is instructed and the enter key is pressed (corresponding to “cancel” in S210), and the display returns to the VICS setting menu display (S100) in FIG.
[0063]
“Point correction” selected to change the point list already registered on the screen 50 in FIG. 7 performs the same process as “point registration” described above. However, the title line in the point list is displayed as “point correction”.
Further, when “Erase Point” is selected on the screen 50 in FIG. 7, the other point display is the same point list display as FIG. 9 except that the title line is “Erase Point” (S300). If a point to be deleted from the list is selected (corresponding to “selection” in S310), the registration data of the corresponding point is deleted (S320), and the display returns to the point list display again (S300). At this time, the name of the deleted point is blank. If the registration of the point A in the point list shown in FIG. 9 is deleted by “point deletion”, the display state returns to that in FIG.
[0064]
In addition, when the name display of each point is to be corrected on the screen 50 of FIG. 7, “point name change” is selected. When “change point name” is selected, the other point display is the same point list display as in FIG. 9 except that the title line is “change point name” (S400), and any of the lists is selected. (Corresponding to “selection” in S410), the screen of the display device 14 is changed to a screen for inputting characters (S420).
[0065]
For example, a hiragana 50-sound table is displayed, and by selecting the hiragana from there, reading by the kana of the name to be displayed is determined, and in response to this determination, it is provided in the ROM of the in-vehicle map display device 2 Search the Kana-Kanji conversion table, convert Kana to Kanji and display it as Kanji. If there is no problem with Kanji conversion, the registered name is changed to the name input in step S420 (S440) by pressing the enter key of the remote controller 15a (corresponding to “input end” in S430). Thereafter, when returning to the display of the point list (S400), the point list is displayed on the display device 14 with the name display of the corresponding point corrected.
[0066]
For example, for point A, if the name display of “Northern Minato-ku Shiba Park” is changed to “West of Minato-ku Shiba Koen”, point A will be replaced by “ “Minato-ku Shiba Park West” is displayed.
Next, when “map display on” is selected on the screen 50 in FIG. 7 to select whether or not to display the VICS indicator during map display by the navigation system, as shown in FIG. As a display for use, a new display 62a for “ON / OFF” is displayed in a form of popping out from the display of the map display ON item 62 (S500).
[0067]
Here, if “ON” is selected by the remote controller 15a (corresponding to “ON” in S510), “VICS indicator ON” is set (S520), and if “OFF” is selected (in S510). “Corresponding to“ OFF ”),“ VICS indicator OFF ”is set (S530). This on / off setting is stored in the RAM of the control circuit 10 in the form of flag set / reset, for example. After this processing, the display again returns to the VICS setting menu display (S100).
[0068]
If it is determined in step S110 that the return key 64 is instructed and the determination key is pressed to cancel, the VICS indicator display process is terminated and the menu display screen as the navigation system is returned.
If the display of the current position is selected from the navigation system menu after setting the VICS indicator on in step S520, a screen 80 as shown in FIG. Here, a road map in which the current position of the vehicle (current position mark 82) is arranged at the center is displayed.
[0069]
A display 84 of the time received from the VICS receiver 24 is displayed in the upper right corner of the screen 80 together with a “VICS” mark, and the points A, B, and C registered as shown in FIGS. There is a corresponding indicator 86. Among these, the symbol A is displayed in red corresponding to the figure 72c of the three automobiles shown in FIGS. Symbol B is displayed in orange corresponding to the figure 74c of the two automobiles shown in FIGS. The symbol C is displayed in blue corresponding to the figure 76c of one automobile shown in FIGS.
[0070]
That is, when there is a traffic jam, the symbol corresponding to the set point is displayed in red, when it is congested, it is displayed in orange, and when the traffic flow is smooth, it is displayed in blue. Although not illustrated, the road closure is displayed in black. Therefore, the driver can easily know the latest traffic information of the point set by himself / herself by color.
[0071]
In the lower right corner of the screen 80, there is a button 88 for returning to the menu of the navigation system, a heading up in which the direction of the map always displays the vehicle traveling direction upward on the screen 80, or the direction of the map is always on the north side. A button 89 or the like for setting whether the north up is displayed upward is displayed and can be selected by the remote controller 15a.
[0072]
In the example of FIG. 12, since the driving position of the vehicle and the point set by the driver for displaying the VICS indicator are distant, there is no corresponding point on the map on the screen 80. For example, the corresponding point is displayed on the screen 80. When appearing on the upper map, as shown in FIG. 13, when a point corresponding to point B appears on the map, the same symbol “B” is displayed to be associated with the traffic information of the indicator 86.
[0073]
For example, if the point B is in a traffic jam state before reaching the current position in FIG. 13, the symbol B of the indicator 86 has changed to red in advance, so the driver has previously considered a route that bypasses the point B in advance. Driving is possible, smooth detouring is possible, and there is no inconvenience of stray or miscarriage, and traffic information can be used truly effectively.
[0074]
In addition, the arrow 87 attached | subjected to the vicinity of the point B of the screen 80 shown in FIG. 13 is displayed in red, and shows traffic congestion. The display of the arrow 87 is performed in the traffic information display process that the in-vehicle map display device 2 performs as a navigation system. The meaning of the color of the indicator 86 and the color of the arrow 87 displayed as the navigation system are unified. That is, also in the arrow 87, red is traffic jam, orange is congested, blue is smooth, and black is closed.
[0075]
As described above, the first embodiment operates as a navigation system and displays map information on the display device 14 as before, and displays map information simultaneously with map information or without displaying map information. The information is displayed to the driver as a separate display from the information.
[0076]
Therefore, the driver can know the traffic information of the point that he really wants to know in real time. If the traffic state at the corresponding point changes during the travel, the traffic information from the FM station also changes immediately, so the color of the indicator 86 also changes immediately. For this reason, the driver can change the driving route in consideration of the color change of the indicator 86, thereby enabling efficient driving and contributing to the realization of a smooth traffic flow.
[0077]
In addition, the color of the symbols A, B, and C displayed to correspond to the points represents the degree of traffic congestion, and the number of automobile figures 72c, 74c, and 76c represents the degree of traffic jam. The traffic condition can be quickly determined, which is preferable for safe driving. 11 is selected (corresponding to “OFF” in S510), and when step S530 is executed, “VICS indicator OFF” is set. In the display of FIG. 13, the received time display 84 and the indicator 86 are erased.
[0078]
  In the first embodimentAndDisplay device 14Is the tableThe VICS receiver 24 corresponds to the receiving means. Steps S150 and S160Is the tableStep S600, S610, and S620 correspond to the processing as the traffic information extracting unit, and the point list shown in FIG. 10 is displayed as in step S200 and the like, and step S220. ProcessingIs the tableControlSteppedCorresponds to the process.
[0079]
[Embodiment 2]
FIG. 14 shows a part of a flowchart of the VICS indicator display process. The process of FIG. 14 shows the process executed in the second embodiment instead of the process shown in FIG. 2 of the first embodiment. Other configurations and processes are the same as those in the first embodiment.
[0080]
Here, Steps S700, S710, S720, S730, S740, S750, and S760 are the same as Steps S100, S110, S120, S130, S140, S150, and S160 of FIG.
Therefore, when one of the points A, B, C is selected from the point list for setting (corresponding to “selection” in S730), the purpose for point registration as shown in FIG. A display 90 of the land-based list is made (S732). The destination list is displayed as “Register destination points” in the title line 90a. Also, in the destination list, transportation item 91, leisure facility 1 item 92, leisure facility 2 item 93, shopping item 94, hotel / hot spring item 95, public facility item 96 and 50 sound search.
