Abstract

PROBLEM TO BE SOLVED: To provide a warning device for an expressway vehicle speed monitoring camera in which frequency of faulty warning output gradually decreases by accumulating data, as a vehicle travels further, whether a vehicle speed monitoring camera is set for an expressway or for a local road, when using data of the vehicle speed monitoring camera such as in Keyhole Markup Language (KML) format which does not include information whether the vehicle speed monitoring camera is set for the expressway or for the local road.SOLUTION: A warning device for an expressway vehicle speed monitoring camera obtains data of a vehicle speed monitoring camera such as in Keyhole Markup Language (KML) format from outside, the data including positional data and vehicle speed limit data but not including information whether the monitoring camera is set for an expressway or for a local road, and displays the monitoring camera as Point of Interest (POI) on a map obtained from the Internet. When traveling on an expressway, the warning device extracts a vehicle speed monitoring camera within a predetermined distance, such as 3 m, from the expressway and issues a warning when a vehicle approaches a predetermined distance from the monitoring camera. At the time, a user confirms and inputs whether the vehicle speed monitoring camera is set for the expressway or for a local road. By the procedure, the warning device does not further issue the warning for the particular vehicle speed monitoring camera for the local road.

Description

  The present invention relates to a vehicle speed monitoring camera warning device that records position data of a speed monitoring camera set on a road and outputs a warning when driving nearby, particularly for a general road installed nearby when driving on a highway. The present invention relates to a high-speed vehicle speed monitoring camera warning device that does not output a warning to a vehicle speed monitoring camera.

  Since vehicles run at a high speed and cause great damage to themselves and others, speed control is carried out by various methods in each country. Among them, vehicle speed monitoring cameras installed on the side or above the road are widely used. It has been. The vehicle speed monitoring camera detects the speed of the vehicle approaching this camera. When the speed is higher than a predetermined speed, the vehicle, the number and the driver are photographed with the camera installed in the same direction, and the photographing date / time data is also captured. The data is recorded or transmitted to the control center.

  Thereafter, the driver of the vehicle that has violated the speed is notified to perform a predetermined procedure, and fines or various disposals are made. Such vehicle speed monitoring cameras have become smaller and cheaper in recent years, and are expected to have a crime prevention effect. Therefore, many vehicle speed monitoring cameras are installed in towns.

  On the other hand, in recent years, navigation devices are widely installed in vehicles. Many navigation devices use map data recorded on DVDs, HDDs, memory cards, etc., and receive GPS signals to determine the current position. A map around the current position is detected and read from the map database, and is displayed superimposed on the current position mark of the vehicle. Furthermore, in the navigation device, when the destination is set, various guidance routes from the current position to the destination are calculated and presented, the guidance route selected by the user is stored, and thereafter, the vehicle safely travels to the destination. In order to be able to do so, guidance is given by screen or voice.

  In such a navigation device, the database as described above is often used as a map database, but it is always connected to an external vehicle data center due to the popularization of mobile phones in recent years and the low price. In addition, the latest map data provided in the data center is taken in and displayed. At that time, an appropriate POI (Point Of Interest) is also taken in and displayed together with the map data, but in addition to that, POI data is taken in from another and used in association with the map data.

  In that case, the map taken in from the data center is accessed mainly by a map database website widely used all over the world, and the map is displayed at an arbitrary scale. Has been widely practiced. The POI used at that time is created in the KML (Keyhole Markup Language) format so that it can be displayed in association with the map data, so that people around the world can use it for a fee or partially free of charge. Provides data. In addition to the KML file as described above, there is software created in an XML (eXtensible Markup Language) file format. For convenience of explanation, a KML file as a representative example will be described below. As described above, the map data widely used all over the world is taken in and displayed using the Internet network, and the desired POI data is taken in from a site suitable for one's preference and displayed on the map. Yes.

  The POI data created in this KML model is also provided for the vehicle speed monitoring camera as described above. In many cases, the user pays for it, imports the data by importing it, and stores it. Necessary items can be superimposed on the currently displayed map to display the POI mark. The POI data of the vehicle speed monitoring camera at this time is the latitude and longitude where the POI is located, the vehicle speed limit speed, and the direction data. The latitude and longitude data are displayed together with the speed limit at a predetermined position on the map. ing.

  However, this KML model data is only the above-mentioned data, and is not recorded in various associations with map data like POI data recorded in a database provided in a normal navigation device. There is no data for distinguishing whether the installation position of the vehicle speed monitoring camera is on a general road or on a highway, which causes problems as described later. In addition, although the common name “highway” may be strictly distinguished from “automobile exclusive road”, these are all referred to as “highway” for convenience of explanation. The same applies thereafter.

  In order to warn that the vehicle speed monitoring camera is approaching using the data of the vehicle speed monitoring camera in the gating device equipped with the normal map database type, the position information, direction information, Japanese Patent Application Laid-Open Publication No. 2004-228561 discloses data including data on whether it is an expressway or a general road. Also, in a navigation device that uses a normal map database format, the vehicle speed monitoring camera information is specified by the road link number, the distance from the link point or the end point, and warning guidance is provided on the highway before the general road. This technique is disclosed in Patent Document 2.

JP 2002-202359 A JP 2000-20891 A

As described above, in the map database provided in the normal navigation device, the POI data is strongly associated with the map data. Therefore, whether the POI of the vehicle speed monitoring camera is at least for general roads or for highways. Often there is data for.
On the other hand, when a map is taken in from a site that provides the map data widely used in the world by connecting to the Internet network as described above, the POI displayed on the map is often KML type, and therefore the vehicle speed monitoring. The camera information includes only position information, speed limit information, and direction information, and it is impossible to identify at least whether the POI is for a general road or a highway.

  Therefore, as shown in FIG. 7, for example, when the vehicle is traveling on a highway, when the POI of the vehicle speed monitoring camera is displayed in front of the highway and close to the road, it is originally a three-dimensional intersection with this road. Despite being set for a general road, it may not be possible to determine whether the road is for a general road or a highway.

  Therefore, when the vehicle approaches the POI installation position within a predetermined distance, a warning is given that attention is required because the vehicle speed monitoring camera is in front of the position corresponding to the speed limit at that time. At this time, even if the driver looks at the screen as shown in FIG. 7, it is difficult to determine at a glance that the vehicle speed monitoring camera is provided for a general road.

  At this time, since the speed limit is 40 km / h, it is possible to estimate that the speed limit is not for a highway, but the speed limit is 40 km / h in a place where construction is being performed for a long time even on a highway. This data may be used as general POI data, and since it generally has a speed limit of 40 km / h, it cannot be used for general roads. Therefore, in the state shown in FIG. 7, a warning is output in anticipation of safety due to the presence of the POI of the vehicle speed monitoring camera. Therefore, for example, when currently driving on an expressway at a speed of 100 km / h, a warning is normally output 600 m before, whereas in such a case, a warning is normally output about 400 m before.

  Such warnings can be dealt with by slowing down even at 400 m when driving at a speed of about 60 km / h on ordinary roads. Because it travels close to 30m, it arrives at the vehicle speed monitoring camera in about 14 seconds, listens to the warning, confirms the current vehicle speed, and performs an operation to decelerate accordingly. It becomes difficult to do so.

  Therefore, when using vehicle speed monitoring camera data for which there is no information about whether the vehicle is for a highway or a general road, the present invention uses high-speed or general road data with simple means as the vehicle travels. It is a main object to provide a high-speed vehicle speed monitoring camera warning device that collects information and outputs fewer false warnings.

  In order to solve the above-described problem, a highway vehicle speed monitoring camera warning device according to the present invention includes at least position data and vehicle speed limit data, and includes data indicating whether the vehicle is for a general road or for a highway. Vehicle speed monitoring camera that captures the data of no vehicle speed monitoring camera from the outside and displays the map of the vehicle speed monitoring camera on the map and the vehicle speed monitoring camera that is close to the traveling highway within a predetermined distance About the vehicle speed monitoring camera extracted by the extraction means, the vehicle speed monitoring camera within the predetermined distance on the expressway, the vehicle speed monitoring camera warning output means for outputting a warning when approaching within a predetermined distance while driving on the expressway, and the vehicle speed When a warning is output by the monitoring camera warning output means, the user's judgment whether the vehicle speed monitoring camera is for a highway or a general road is input. When the user gives an instruction that the vehicle speed monitoring camera is for a general road, the vehicle speed monitoring camera is extracted after that. The means is characterized in that it is not extracted in the warning output processing of the expressway.

  Further, the vehicle speed monitoring camera warning device for a highway according to the present invention is the vehicle speed monitoring camera warning device for a highway, wherein the vehicle speed monitoring camera extracting means includes a vehicle speed monitoring camera extraction unit within a predetermined distance from the highway with respect to the highway in the guide route. A vehicle speed monitoring camera that is close to the vehicle is extracted.

  Further, the highway vehicle speed monitoring camera warning device according to the present invention is the highway vehicle speed monitoring camera warning device, wherein the vehicle speed monitoring camera extraction means is close to the highway within a predetermined distance when traveling on the highway. It is characterized by extracting a vehicle speed monitoring camera.

  In addition, the highway vehicle speed monitoring camera warning device according to the present invention is the highway vehicle speed monitoring camera warning device, wherein the vehicle speed monitoring camera extracting means is configured such that when the vehicle speed monitoring camera detects a limit vehicle speed that is greater than or equal to a predetermined value, The vehicle speed monitoring camera is extracted as being for a highway.

  The highway vehicle speed monitoring camera warning device according to the present invention is the highway vehicle speed monitoring camera warning device, wherein the map data for displaying the mark of the vehicle speed monitoring camera is taken from a map providing site on the Internet. The data of the vehicle speed monitoring camera is KML type data.

  Further, the highway vehicle speed monitoring camera warning device according to the present invention is the highway vehicle speed monitoring camera warning device, wherein when the vehicle speed monitoring camera approaches the vehicle speed monitoring camera, the vehicle speed monitoring camera is not included in the confirmation instruction display. It is characterized in that an output for prompting confirmation of whether or not it exists is performed.

  Since the present invention is configured as described above, when using the data of the vehicle speed monitoring camera for which there is no information on whether the vehicle is for a highway or a general road, the vehicle can be It is possible to collect data for general roads so that erroneous warnings are not gradually output.

It is a functional block diagram of the Example of this invention. It is an operation | movement flowchart of the Example. It is an operation | movement flowchart of the process performed by FIG.2 S7. It is an operation | movement flowchart of another Example. It is a figure which shows the process aspect of this invention. It is a figure which shows the other process aspect of this invention. It is a figure which shows a prior art example.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram of a vehicle speed monitoring camera warning device for a highway of the present invention, and shows an example in which the present invention can be implemented in various modes. Any of these can be selected and implemented in various ways. In addition, the function part which performs each function in the figure can be said to be a means which performs each function.

  In the embodiment shown in FIG. 1, an example in which the highway vehicle speed monitoring camera warning device of the present invention is incorporated in a navigation device 1 is shown. In this navigation device 1, from an external map data providing site 3, For example, map data is imported by the communication unit 4 connected to a mobile phone or the like, and the minimum necessary data is stored in the map data storage unit 10. The map data in the navigation device 1 at this time is stored by downloading various POI data from a vehicle travel guidance data providing site by connecting an external data recording medium such as a USB memory to a personal computer at home, for example. It is also possible to connect a USB memory or the like storing such data to the navigation device and read and use it.

  Various POI data such as vehicle speed monitoring camera installation data is also imported from the vehicle travel guidance data providing site 2 and stored in the vehicle travel guidance data storage unit 5 in particular. The data stored at this time is a KML model that matches the format of the map data. The data stored in the vehicle travel guide data storage unit can be stored by fetching various data from the vehicle travel guide data providing site 2 that is present in an extremely large number.

  The various data captured at this time have various data reliability depending on the provider, and there are also unreliable data. Therefore, especially the data of the vehicle speed monitoring camera described later is important, and the reliability of the operation of the present invention It is important to import data from a highly reliable site.

  In the example shown in the drawing, the high-speed monitoring camera installation data 6 used in the present invention can be stored, and as this high-speed monitoring camera installation data, the installation position 7 consisting of the latitude and longitude data of the installation location, the vehicle speed monitoring camera Data on the speed limit 8 and the monitoring direction 9 of the vehicle speed monitoring camera is stored.

  As will be described later, when the vehicle speed monitoring camera is installed near the highway by the user's input as the vehicle travels, it is found that the vehicle is for a general road. However, in the example shown in the figure, an example of storing in the general road vehicle speed monitoring camera confirmation storage unit 17 described separately from these storage units is shown. However, you may make it memorize | store this memory | storage part in the vehicle travel guidance data storage part 5 so that it may add to the data taken in by the communication part 4. FIG.

  The navigation apparatus 1 includes a current position detection unit 11 as in the case of the conventional one, and uses a GPS, and further detects an accurate current position using a vehicle speed pulse, a gyro, or the like as necessary. The guide route calculation unit 12 calculates and presents guide routes according to various conditions when a destination is set by a destination setting unit (not shown). When the user selects and instructs the calculation result of the guidance route, the guidance route is stored in the guidance route storage unit 13. Based on the guidance route data stored in the guidance route storage unit 13, the navigation apparatus provides appropriate guidance in accordance with the current position.

  The highway detection unit 14 detects a highway that is to pass through the guidance route stored in the guidance route storage unit 13. This can be implemented by searching for data having the attribute of a highway for the road link indicating the guidance route. The highway travel detection unit 15 is currently traveling along the highway based on the position data of the highway detection unit 14 that detects the highway on the guidance route and the position data detected by the current position detection unit 11. An example of detecting this is shown.

  The highway travel detection unit 15 calculates the guidance route by the navigation device and implements the present invention even when the vehicle is not traveling along the route, that is, when the vehicle is traveling normally without the guidance route. When it is detected that the current position of the current position detection unit 11 is traveling along the expressway on the map data, it is detected that the vehicle is traveling on the expressway.

  The vehicle speed monitoring camera extracting unit 16 within a predetermined distance on the highway extracts a vehicle speed monitoring camera existing within a predetermined distance along the highway. Here, for example, all the vehicle speed monitoring cameras existing within 3 m on the expressway or within 1 km ahead of the vehicle and within a predetermined angle in the direction of travel are extracted temporarily. Extract surveillance cameras.

  The vehicle speed monitoring camera confirmation recording unit 17 for general roads extracts a vehicle speed monitoring camera located in the vicinity of the expressway while the vehicle is running on the expressway, as will be described later, and gives a warning when the vehicle is actually running. When the user confirms that the vehicle speed monitoring camera was not installed for the expressway at that time, it was confirmed that the vehicle speed monitoring camera was for general roads when the input was made. Record it here. However, as described above, it can also be stored in the vehicle speed monitoring camera installation data storage unit 6.

  The map display unit 18 is a processing unit that performs basic processing included in the navigation device 1, and also displays a map as shown in the map display example 24. In this figure, an example similar to the conventional example shown in FIG. 7 is shown, and an example in which an erroneous warning is easily performed due to the presence of a vehicle speed monitoring camera close to the expressway is shown.

  In the vehicle speed monitoring camera warning output processing unit 19, the vehicle speed monitoring camera warning start point setting unit 20 selects a point where the warning is started. Here, for example, when the speed limit is 120 km / h, considering that there is a possibility that the vehicle is currently traveling at a speed of about 140 km / h, warning output is started from, for example, 800 m before the vehicle speed monitoring camera is installed. . On the other hand, when it is limited to 40 km on a general road, it can be decelerated in a relatively short time. For example, a warning is output from a distance of 50 m. It is set in various ways depending on whether or not it is known.

  The vehicle speed monitoring camera approach detection unit 21 travels the point set by the vehicle speed monitoring camera warning start point setting unit 20 and then further approaches the vehicle speed monitoring camera to determine whether or not the vehicle speed monitoring camera actually exists on the expressway. In order to output the timing for checking, it is detected that the vehicle has sufficiently approached the vehicle speed monitoring camera.

  In the general road vehicle speed monitoring camera confirmation instruction display unit 22, as shown in the map display example 24 of FIG. 1 and as shown in the conventional example of FIG. 7, the vehicle speed monitoring camera originally installed on the general road. When a warning is output due to being installed within a predetermined range of the expressway, for example, a confirmation instruction display as shown in FIG. 6 is performed. Although FIG. 6 shows an example of the display “whether the current speed monitoring camera was for a highway”, other than that, “whether the current speed monitoring camera was for a general road”, etc. Various displays can be performed for the same purpose.

  As shown in FIG. 6, the general road vehicle speed monitoring camera confirmation instruction unit 23 displays “Yes” and “No”, and there is a confirmation instruction when the user performs a touch operation on this portion. Shall. As a result of the confirmation instruction, it is recorded in the general road vehicle speed monitoring camera confirmation recording unit 17 that it has been confirmed by actual traveling as described above. Thereafter, when traveling on the expressway, the above-described confirmation instruction display or the like is not necessary without extraction by the vehicle speed monitoring camera extraction unit within a predetermined distance on the expressway.

  In the present invention comprising functional blocks as shown in FIG. 1, it can be carried out, for example, according to the operation flow shown in FIG. In the first example of the high-speed vehicle speed monitoring camera warning output optimization process shown in FIG. 2, it is determined whether or not the initial vehicle speed monitoring camera installation data is newly imported from the providing site (step S1). When the user captures completely new or additional vehicle speed monitoring camera installation data, the process proceeds to step S2 to place the imported POI mark with vehicle speed monitoring camera data at a predetermined position on the map captured on the web. . This operation may be performed at least within the range of the map currently displayed on the screen.

  Thereafter, in the example of FIG. 2, when it is determined in step S1 that the vehicle speed monitoring camera installation data is not newly imported from the providing site, the process proceeds to step S3 to set the guidance route. That is, the example of FIG. 2 shows an example when a guidance route exists, and in the second embodiment of FIG. 4, the present invention can be implemented even when the guidance route does not exist. It differs in that it shows an example.

  After setting the guide route in step S3, an expressway on the guide route is detected (step S4). In these processes, the guide route is calculated by the guide route calculation unit 12 of FIG. 1 and the guide route selected by the user is stored in the guide route storage unit 13, and then the highway detection unit 14 includes the highway traveling portion. It is done by detecting.

  Next, a vehicle speed monitoring camera on the highway and close to the highway is extracted (step S5). When extracting the vehicle speed monitoring camera at this time, the extraction process can be performed in various modes assuming that the vehicle is close to the expressway. For example, as shown in FIG. Overall, the link latitude / longitude data, which is data of the expressway, can be set within a range of 5 m from the link, for example, or the road width can be obtained from the road data. Can be implemented.

  After that, the warning start point of the unconfirmed low-speed limited vehicle speed monitoring camera is set so as to warn early for the highway. That is, when there is a low-speed limited vehicle speed monitoring camera such as 40 km / h that has not been confirmed yet, this means that the highway is traveling at a high speed considering that the vehicle speed is limited to a low speed due to construction for a long period of time. Even so, the warning is set so that it can be decelerated to 40 km / h with a margin. Next, in step S7, a vehicle speed monitoring camera installation position warning output and data maintenance process during highway traveling are performed as shown in FIG.

  In the same process shown in FIG. 3, it is determined whether or not a warning point of the vehicle speed monitoring camera has been reached (step S2) from the state of first traveling on the highway (step S11). Here, when it is determined that the vehicle speed monitoring camera on the high speed road and in the vicinity of the highway extracted in step S5 in FIG. 2 is not yet a warning point, the process proceeds to step S18, where the highway is exited. If it is not yet determined, the process returns to step S11 to continue the highway and perform the same processing. On the other hand, when it is determined in step S18 that the vehicle has left the highway, the process proceeds to step S19 and returns to step S1 in FIG. 2 to perform a new process.

  When it is determined in step S12 that the warning point of the vehicle speed monitoring camera has been reached, a vehicle speed monitoring camera approach warning is output in step S13. Next, for the vehicle speed monitoring camera, it is displayed whether the warning output at the time of high speed traveling is to be canceled (step S14). This display is as shown in FIG.

  Thereafter, in the example shown in FIG. 3, the vehicle speed monitoring camera installation position is output by voice or the like (step S15), the user is sufficiently alerted, and in step S16, there is a monitoring camera on the highway. The user determines whether or not. Here, when it is confirmed by looking at the camera located on the side or top of the road that the vehicle speed monitoring camera is for high speed, the process proceeds to step S20 and the vehicle speed monitoring camera is for highway use. Confirm and set. This processing can be performed, for example, by selecting and indicating “Yes” when the display of FIG. 6 is performed.

  When the user determines in step S16 that the vehicle speed monitoring camera does not exist on the expressway, that is, when the user selects and instructs “No” in the display of FIG. 6, the process proceeds to step S17, and the vehicle speed monitoring camera includes After that, it is set to cancel the warning output when driving on the expressway. By this process, the warning output is not performed even in the vehicle speed monitoring camera installed in the vicinity of the expressway thereafter.

  After that, after the processing of step S20, and when it is not the warning point of the vehicle speed monitoring camera in step S12 as described above, the process proceeds to step S18, and it is determined whether or not the motorway has been exited as described above. If the vehicle has not yet exited, the operation returns to step S11 and the operation is repeated while continuing to drive on the highway. On the other hand, when it is determined that the motorway has been exited, in step S19, the process returns to step S1 in FIG. 2 to perform new processing.

  FIG. 4 shows a second embodiment of the high-speed vehicle speed monitoring camera warning output optimization process, in which the present invention can be implemented even when the navigation route by the navigation device is not set. An example is shown. That is, in the process of FIG. 4, first, as in the example of FIG. 2, it is determined whether or not the vehicle speed monitoring camera installation data is newly imported from the providing site. If it is determined here that it has been newly imported, the imported POI mark with vehicle speed monitoring camera data is arranged and displayed at a predetermined position of the map captured on the web in step S22.

  Thereafter, in step S21, when it is determined that the vehicle speed monitoring camera installation data is not newly imported from the providing site, the process proceeds to step S23 and travels on the highway. That is, in the example of FIG. 2, the guide route is set here, and thereafter, processing according to the guide route is performed, whereas in the example of FIG. Go.

  Next, a vehicle speed monitoring camera existing at a predetermined radius and within a predetermined angle from the vehicle position is extracted (step S24). In this process, for example, as shown in FIG. 5B, a vehicle speed monitoring camera existing in a range of an angle α from the current position and within a predetermined distance r from the current position is extracted. The angle α and the distance r at this time can be arbitrarily set as necessary. This process is performed while traveling on a highway. Therefore, it is preferable to end the process including a series of subsequent processes at least about 1 km before considering the warning output start distance.

  In the example of FIG. 4, subsequently, a vehicle speed monitoring camera having a predetermined speed or higher is set as a highway vehicle speed monitoring camera. That is, since there is no high speed limit such as 80 km / h or 100 km / h on a general road, a vehicle speed monitoring camera with such a vehicle speed limit is for a highway and does not require subsequent processing. .

  In the subsequent step S26, among the vehicle speed monitoring cameras below the predetermined vehicle speed, the vehicle speed monitoring camera within a predetermined distance on the expressway is set to output a warning. Here, within a predetermined distance, a range within a predetermined distance within the range of the predetermined angle α shown in FIG. 5B can be selected, but this selection is performed as the first extraction process in a series of processes. After that, the same range as in FIG. 5A may be narrowed down, and the range may be set for warning output.

  Next, the warning start point of the unconfirmed low-speed limited vehicle speed monitoring camera is set to warn early for the expressway. Since this process is the same as step S6 of FIG. 2, the description thereof is omitted. .

  Thereafter, in step S28, similarly to step S7 in FIG. 2, warning output at the installation position of the vehicle speed monitoring camera and data maintenance processing are performed when traveling on the highway as shown in FIG.

  By performing such processing, for example, when entering an expressway, the vehicle will not leave the expressway until at least the next interchange. A camera that has been detected and has not yet been confirmed can be set to output a warning, and the above processing can be performed. Further, when the next interchange has passed, by continuing the process in the same manner, the warning process and the data maintenance as described above can be surely performed until leaving the expressway.
