Description

  The present invention relates to a road map providing system that creates a road map using traveling data of an unspecified number of vehicles.

As a system that can instruct a driving route to a driver, a vehicle car navigation system has become widespread. The car navigation system includes a GPS device for acquiring the vehicle position and a storage medium such as a CD-ROM or a hard disk drive that stores a road map, and uses a road map stored in the storage medium. It is possible to show the driver information such as the position of the vehicle, the travel route, the gas station, and public facilities.
Road maps, which are important data for car navigation systems, are constantly being updated as roads are newly established or abolished. Since map data has a large capacity, it is stored on the vehicle side. If the road changes or is newly established, the map needs to be updated. A method of acquiring the updated content as difference data on the vehicle side by communication has also been proposed, but in that case, communication costs are required. In reality, there are many users who regularly purchase a map once every several years, or update the car navigation system itself at the time of vehicle purchase, considering the cost of road update frequency.
On the other hand, even manufacturers on the side of providing car navigation systems have a considerable cost for creating maps. Manufacturers need to provide the latest road maps, but they want to keep the maintenance costs as low as possible. The user driving the vehicle wants to use the latest map as cheaply as possible.
Therefore, a method of creating a road map by using aerial photographs and extracting roads from the obtained images is generally used, but there is a problem that it takes a high cost for photography and photo analysis.
On the other hand, there is a road map creation system as disclosed in the following Patent Documents 1 to 3.
JP-A-11-167343 JP 2002-318533 A JP-A-6-201392

According to the technique disclosed in Patent Document 1, position information of an unspecified number of vehicles can be collected by communication means. The obtained position information is a set of dots, and road map data can be created by linearly processing the dot data.
Further, according to the technique disclosed in Patent Document 2, it is possible to create a more accurate map in consideration of not only simple vehicle position information but also the vehicle width.
Further, according to the technique of Patent Document 3, it is possible to create road data in a tunnel that is difficult to create by aerial photography or GPS.
By the way, as one function of the car navigation apparatus, there is a route search function. This function searches the route to the destination using the road map data held by the device. Many route search functions are programmed to prioritize the main road and formulate a travel route.
Car navigation system users include not only regular cars but also large-sized cars and taxis. Since some roads cannot be traveled by the user, the travel route of the search result does not necessarily mean that the user can travel.

In the technique described in Patent Document 1, a collection of dots obtained by voting from a vehicle travel position is used. The obtained data is a dot that represents the location of an unspecified number of vehicles, which is suitable for the purpose of creating a simple road map, but the direction and speed of each vehicle going forward, We do not know the attributes of individual vehicles, such as the classification of vehicles such as small cars, the classification of commercial vehicles or private cars, and the purpose of travel.
In the technique described in Patent Document 2, a more detailed road map can be created. However, it is not known from the created road map whether, for example, large vehicles can pass. Further, like the road map according to the method of Patent Document 1, even if the distance to the destination is known, there is no way to know the estimated required time to the destination. This is because the average speed on the road is unknown.
Furthermore, in the technique of Patent Document 3, it is possible to correctly add a newly created road to an existing map. However, the addition of roads by this method is not intended for an unspecified number of people as in the method of Patent Document 1, so it is necessary for the investigator to go to each road and run the car, and the road map is maintained. There is a problem that the cost for the increase.

FIG. 1 is a system configuration diagram showing an embodiment of a road map providing system according to the present invention.
The road map providing system shown in the present embodiment receives an in-vehicle device 100 having a road map search / guidance function and travel history information collected by the in-vehicle device, and the road map providing server 300 receives a network 400 such as the Internet. The relay station 200 that relays and transmits the travel history information collected by the plurality of in-vehicle devices 100 from the relay station 200 via the network 400, statistically processing the received travel history information, and the travel of each vehicle The road map providing server 300 creates a road map for each purpose and attribute.

The in-vehicle device 100 receives a radio wave from a GPS satellite, detects a traveling position information of the own vehicle, a GPS receiving unit 101, a storage unit 102 that stores road map information, and a clock 103 that outputs date information. , A sensor unit 104 that detects a moving speed, a moving direction, and a tilt of the own vehicle, an input unit 105 that inputs a destination and a traveling purpose and attributes of the own vehicle, and a road map that leads to the destination is displayed on a display screen The traveling unit 106 communicates with the relay station 200, and the traveling position information detected by the GPS receiver 101 is stored in the storage unit 102 as traveling history information together with the date / time information output by the clock 103. An information processing unit 108 that sequentially records and retrieves a road map to a destination from a road map stored in the storage unit 102 is provided.
The storage unit 102 can use a temporary storage memory, a hard disk drive, or the like, but in order to obtain the latest map information provided from the server 300 of this system as needed and keep the map for navigation the latest, the hard disk A drive is preferred. If the purpose of the user of each vehicle is only to provide the travel history information to the road map providing server 300, a memory for temporary storage may be used.
The in-vehicle device 100 that provides the travel history information to the road map providing server 300 is mounted on the member's vehicle recruited by the operating organization of the road map providing server 300, and the travel history information is obtained by performing member registration. A program for transmission is distributed, and by installing this program in a general-purpose car navigation device, a function for receiving a travel history information transmission function and receiving the latest road map information from the road information providing server 300 is added. It becomes the in-vehicle device 100.

The relay station 200 records the received traveling history information in the storage unit 203 and the communication unit 201 that receives the traveling history information from the in-vehicle device 100, and provides a road map when the traveling history information of a predetermined number of vehicles can be collected. The latest road map information stored in the storage unit 203 is transmitted to the in-vehicle device 100 by communication with the in-vehicle device 100 and transmitted to the server 300 via the network 400, and the road stored in the in-vehicle device 100. An information processing unit 202 that performs processing for updating the map information to the latest one is provided.
The relay station 200 is installed in a site such as a gas station or a company, for example.
By installing in a site such as a gas station or a company and automatically detecting the travel history information collected by each in-vehicle device 100 to the relay station 200 when each in-vehicle device 100 detects the presence of the relay station 200, Collection can be performed without making the user aware of the operation of transmitting the travel history information.
Further, the user of the in-vehicle device 100 can store the latest road map data in the storage unit 102 without being aware of the road map update operation.
In this case, in the form in which the travel history information collected by each in-vehicle device is recorded in a storage medium such as a card memory or in a contactless manner, the storage medium such as the card memory is not connected via the communication unit 201. The data is directly captured and stored in the storage unit 203.
The travel history information in the storage unit 102 collected by the relay station 200 is deleted by a command from the relay station 200 in order to prevent duplicate collection to the road map providing device 300.
In the form in which the travel history information collected by the user of the in-vehicle device 100 in the storage unit 102 is directly transmitted to the road map providing server 300 via the Internet or the like, it is not necessary to install the relay station 200.

The road map providing server 300 includes a communication unit 301 that receives a road map search request from the in-vehicle device 100 and travel history information from the relay station 200, and travel history information of a plurality of vehicles received from the relay station for each travel purpose and attribute. Information that performs statistical processing, creates a road map according to driving purpose and attribute, stores it in the database 303, and periodically transmits the latest road map information stored in the database 303 to the relay station 200 A processing unit 302 is provided.
In this case, the road map providing server 300 creates road map information based on the travel history information collected up to, for example, 10 minutes before the current time, and immediately transmits the road map information to the relay station 200 as the latest road map information. .
If the in-vehicle device 100 can communicate with the road map providing server 300 and the relay station 200 via a network such as the Internet, the road map can be obtained by transmitting a road map search request from the in-vehicle device 100. The providing server 300 returns the search result information directly without going through the relay station 200.

FIG. 2 is a diagram illustrating a configuration example of travel history information recorded in the storage unit 102 by the in-vehicle device 100, and includes date, time, day of the week, vehicle identifier, passing point latitude, passing point longitude, passing point direction, and passing point speed. It consists of vehicle attribute information.
The vehicle identifier is a unique identification number (numerical value) assigned to the vehicle on which the in-vehicle device 100 is mounted at the time of member registration.
As shown in the example of FIG. 3, the vehicle attribute is a use form of a vehicle such as a private vehicle, a business vehicle, a two-wheeled vehicle, a cargo transporter, a passenger transport vehicle (taxi), a passenger transport vehicle (bus), It represents a classification of a vehicle type such as a car and a small car, and can be arbitrarily set depending on what kind of road map is created. For example, the vehicle weight and height, the weight and height when loading a load, and the like may be set.

FIG. 4 is a diagram showing a configuration example of member information registered in the database 303 of the road map providing server 300, which includes information such as vehicle identifier, vehicle attribute, purpose of use, user name, address, and contact information. Yes.
As shown in FIG. 5, the purpose of use is the purpose of mainly using vehicles owned by the respective members, such as sightseeing, commuting, shopping, and passenger business.
In this case, the private car is often used for various purposes such as shopping, commuting, and sightseeing. However, the main purpose is to be registered in the database 303, and the input unit of the in-vehicle device 100 is used for actual use. The purpose of use input from 105 is used when collecting the travel history.
When collecting the travel history information, the actual use purpose is input at the input unit 105 of the in-vehicle device 100 to travel.
In the storage unit 102 of the in-vehicle device 100, the vehicle type and the vehicle attribute are registered in advance at the time of member registration.

  FIG. 6 is a diagram showing a specific example of member information registered in the database 303, and the vehicle identifier, vehicle type, purpose of use, user name, address, and contact information are registered according to the data structure of FIG.

FIG. 7 shows an example of the travel history information recorded in the database 303, and shows the travel history of the vehicles with vehicle identifiers = 101 and 501.
A travel history is registered for a private car member with vehicle identifier = 101 and a taxi company vehicle with vehicle identifier = 501.
In this example, the point of latitude 43.3.41 and longitude 141.21.11 is Sapporo Station, the point of latitude 43.3.6 and longitude 141.21.15 is Susukino Station, latitude 42.46.27 The point of longitude 141.39.31 is New Chitose Airport. It can be seen that the private car in this example left Sapporo Station at 7:00, passed through Susukino Station at 7:05, and passed through New Chitose Airport at 7:50. In this way, the time when the plurality of vehicles have passed around Sapporo Station and New Chitose Airport is stored in the database 303.
In this example, since the date is also included in the items of the database 303, it is possible to determine the required time and the optimum route according to the season and day of the week.
It can also be seen that the taxi in this example was at Sapporo Station from 8:00 to 8:30. It is assumed that the customer waiting time was 30 minutes. After that, it goes to Susukino Station, but it is also possible to create a daily report from such driving history.
In this example, the travel point data is acquired at 10-minute intervals, but this may be arbitrarily determined. If the setting is short, more detailed driving data can be acquired.
By acquiring the travel history information of many vehicles, the travel history information collected in the server 300 is increased, and statistical significance comes out. If there is a road that is closed during the winter season, the travel history information for that section is not collected in the server 300 during the winter. Members of large vehicles such as dump trucks gather large roads through which large vehicles can pass reliably. By creating a road map based on the data collected in this way, it becomes possible to provide a member with a map that meets the needs of the member.

FIG. 8 is a sequence diagram illustrating processing of the in-vehicle device 100, the relay station 20, and the map information providing server 300.
When the user of the vehicle equipped with the in-vehicle device 100 starts the engine, the information processing unit 108 of the in-vehicle device 100 opens a travel history file stored in the storage unit 102 (step 801).
Next, when the user inputs the purpose of use (sightseeing, commuting, etc.) from the input unit 105, the input purpose of use is registered in the storage unit 102 (step 802).
Next, if there is an interrupt from the timer built in the information processing unit 108, the current position (passage point latitude, passing point longitude) detected by the GPS receiving unit 101, the sensor unit 104 detects Travel data such as the travel speed and travel direction (step 804), the purpose of use input by the user for the travel data, the current date, time, day of the week information output by the clock 103, and the storage unit 102 A vehicle identifier stored in advance is added and written in the travel history file as travel history information (step 805).
Next, when the vehicle arrives at a gas station, for example, and receives a data transmission command transmitted from the relay station 200 installed at this time (steps 806 and 807), the system is unique to the relay station 200. Then, the travel history information stored in the travel history file of the storage unit 105 is transmitted to the relay station 200 (step 808).

The relay station 200 that has received the travel history information stores the received travel history information in the storage unit 203. And the latest road map information memorize | stored in the memory | storage part 203 is read, and the vehicle identifier which designates a transmission destination is added to this, and it transmits (step 809).
In this case, road map information corresponding to all of the purpose of use and vehicle attributes is stored in the storage unit 203 of the relay station 200, but if there is no special designation from the in-vehicle device 100, it corresponds to the attribute of the vehicle. Send road map information for all usage purposes. However, when the purpose of use is set in advance so as to be designated by communication with the relay station 200, only the road map information corresponding to the purpose of use is read and transmitted for the attribute of the vehicle.

The in-vehicle device 100 that has received the road map information confirms that the vehicle identifier is the same as its own vehicle identifier, causes the received road map information to be stored in the storage unit 102, and the road map stored in the storage unit 102. The information is updated to the latest one (step 810).
Next, when the user inputs a destination for route search, the optimum route from the current location to the destination is searched based on the latest road map information stored in the storage unit 102 (step 815). The result is displayed on a display unit (not shown) (step 816).
If a specific section of the route search result is designated, the moving speed and required time of the specific section are displayed on the display unit (step 818). The user can predict the degree of congestion in a specific section based on the display content.
Next, it is determined whether or not the engine has been stopped (step 819). If not, the process returns to step 803 and the same operation is repeated. If the engine is stopped, the travel history file is closed and the process ends (step 820).

On the other hand, when the traveling history information for a predetermined number of vehicles is accumulated (step 811), the relay station 200 transmits the accumulated traveling history information to the road map information providing server 300 via the network 400 (step 811). 812).
The road map information providing server 300 that has received the travel history information statistically processes the received travel history information, creates road map information for each purpose of use and attribute, and stores it in the database 303 (step 818). Then, the road map information is transmitted to the relay station 200, and the road map information stored in the relay station 200 is updated to the latest one.

The statistical processing in the road map information providing server 300 is to map the position information (latitude and longitude) in the travel history information on the white map as shown by the black circles in FIG. 9, and recognize the presence of the road based on the result. This is a process for creating a road map.
This statistical processing is performed for each purpose of use and attribute.
As a result, as shown in the map information configuration diagram of FIG. 10, a plurality of maps in which the purpose of use and the attributes are combined are created.
For example, if the map for which the purpose of use is “sightseeing” is as shown in FIG. 11 (a), when attribute = bus and attribute = taxi are combined with this, FIG. 11 (b), (c) ) Is created.
The in-vehicle device 100 can acquire from the relay station 200 road map information that matches the purpose of use of the host vehicle or the purpose of use and attributes.

As described above, the present invention creates road map information in which physically existing roads are classified according to actual usage purposes and vehicle attributes based on the travel history information collected from the in-vehicle device 100, and the road map. Information is provided to the user.
Therefore, it is not necessary to take time and effort such as a field survey, and road map creation costs and maintenance costs can be reduced.
In addition, on the in-vehicle device side, the latest road map created by the road map providing device can be obtained by travel purpose and attribute, so it is optimal for travel purposes such as travel, luggage transportation, commuting, etc. and vehicle attributes This makes it possible to search for a simple route.
In addition, the road map providing device changes depending on, for example, a school zone where traffic is prohibited at 8am, a road where right turns are prohibited during busy hours, bus lanes where traffic is prohibited from 7am to 10am, and time of day. The road map according to the actual traffic condition can be provided such as the center line to be used and the section where the loading weight and height are limited. Note that the road map creation processing time interval in the road map creation device can be arbitrarily set. However, when the processing time is long, the road map creation device can be configured to be installed in each region for distributed processing.
In addition, the number of vehicles in the section unit equipped with the in-vehicle device is measured by the position signal from the in-vehicle device and the vehicle identifier, and for example, a ratio with the average value in the monthly unit is calculated, and the traveling in the section according to the ratio The color of the lane can be changed so that the degree of congestion can be understood.

One road map information providing server 300 may be installed nationwide, or in units of prefectures or counties, cities, towns or villages.
In addition, the relay station 200 installed at a gas station or the like can be configured to provide, for a fee, map information only for the municipality where the installation is located.
