Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention belongs to the technical field of a vehicular map processing system that obtains update information of map data used in a vehicle-mounted device from a vehicle-mounted device and updates map data stored in a center.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, when a road is newly constructed or disappears due to road expansion work or the like, road map information is updated by aerial photography or actual surveying at the site.
According to this method, a great deal of cost and man-hours are required, so that the information update itself is performed once a year. In such a case, a route guidance other than the actual shortest route is performed, for example, when a route is searched, and the original function cannot be sufficiently exhibited.
On the other hand, the conventional road map information updating system performs map matching between the traveling locus of the vehicle and the map data, sets a road outside a predetermined range of the map data as a road leaving state, and updates the map data with the traveling locus. (For example, see Patent Document 1).

[0004]
[Problems to be solved by the invention]
However, in the conventional vehicular map processing system, roads adjacent to the existing road are updated by map matching in order to update the road information when it is determined that the vehicle has departed from the existing road by map matching. Could not be detected because it was determined that the vehicle had not left the road.
For this reason, a branch road from an existing road to a newly-built building or road, a newly created detour, a new road running alongside an existing road, and the like are not detected, and the update of map data by a conventional method is awaited. There was a problem that had to be.
[0005]
The present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicular map processing system that can detect a road adjacent to an existing road as a new road. It is in.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, a vehicle includes a trajectory calculation unit that calculates a trajectory of the vehicle from vehicle position information and road map information, and a vehicle information collection device that includes a communication unit with the outside. Communication means with the vehicle information collecting device, locus storage means for temporarily storing the running locus from the vehicle information collecting device which does not match the road map information, and running locus from the vehicle information collecting device obtained by the communicating means And a comparison determination unit that at least compares and determines whether the traveling locus of the locus storage unit substantially matches the travel locus of the locus storage unit or the road map information. A map information processing device comprising updating means for updating road map information with the traveling locus as a new road is provided outside the vehicle,
The means is constituted by a vehicle information collection device and a map information processing device.
[0007]
According to a second aspect of the present invention, the vehicle information collecting apparatus includes a vehicle determining unit that determines whether or not the traveling locus calculated by the locus calculating unit matches the road map information. And
[0008]
According to a third aspect of the present invention, the vehicle information collection device includes a vehicle trajectory storage unit that temporarily stores the traveling locus when the vehicle determining unit determines that the traveling locus does not match the road map information. It is a characteristic means.
[0009]
According to the fourth aspect of the present invention, the vehicle determining means of the vehicle information collecting device, when the running locus calculated by the locus calculating means and the running locus temporarily stored in the vehicle locus storing means coincide with each other a plurality of times, sends the running locus to the map information processing device. Is transmitted by the communication means.
[0010]
In the invention described in claim 5, the traveling locus includes information indicating the traveling direction, and the comparison determining means of the map information processing device determines that the traveling locus from the vehicle information collecting device is the same as the traveling locus of the locus storage means. The updating means determines that the road is a one-way road and updates the road when the vehicle substantially coincides a plurality of times and the traveling direction of the traveling locus coincides a plurality of times.
[0011]
In the invention according to claim 6, the traveling locus includes time information when the vehicle travels along the locus, and the comparison and determination unit of the map information processing apparatus determines that the traveling locus from the vehicle information collecting apparatus is a locus storage unit. When the traveling locus substantially coincides with the traveling locus a plurality of times and the time when the traveling locus travels does not exist in an arbitrary time zone, the updating unit determines that the road is time-regulated and updates the road. It is a characteristic means.
[0012]
According to the invention described in claim 7, the traveling locus includes a traveling direction, time information when the vehicle travels along the locus, and vehicle speed information. The road map information is updated by judging the road width from the information and the vehicle speed information.
[0013]
According to the invention described in claim 8, the map information processing apparatus detects sudden congestion from the traveling direction of the traveling trajectory from the vehicle information collecting apparatus, time information, vehicle speed information, and road width determined by the updating means. And congestion detecting means for transmitting congestion information by communication means.
[0014]
Function and Effect of the Invention
According to the first aspect of the present invention, the traveling locus that does not match the road in the road map information is temporarily stored in the locus storage unit without being applied to the road in the road map information by map matching. Therefore, even if the traveling locus is adjacent to the road of the road map information, it is not regarded as the road of the road map information. After that, the traveling trajectory sent from the vehicle information collecting device by the communication means is compared with the traveling trajectory stored in the trajectory storing means or the road map information by the comparing and judging means. Therefore, the road adjacent to the road of the road map information that is determined to match the road map information in the conventional map matching will coincide with the traveling locus of the locus storage means, and this is repeated a plurality of times, and When the property increases, the road map information is updated as a new road by the updating means. Therefore, a new road adjacent to an existing road can be detected and road map information can be updated without spending manpower and costs as in the related art.
The "substantially coincident" determined by the comparison determination unit is a substantial coincidence determined in consideration of the number of lanes, and a comparison is made so that the traveling locus or the own vehicle position, which has been conventionally performed, matches the road map information. It is not something that moves the target significantly.
[0015]
According to the second aspect of the present invention, the vehicle information collecting device is provided with a vehicle determining unit. Since the vehicle determination means compares and determines whether the traveling locus and the road map information match, the traveling locus when the traveling locus clearly matches the road map information can be prevented from being transmitted to the map information processing apparatus. The load on the information processing device can be reduced. This also reduces the equipment cost of the map information processing device.
[0016]
According to the third aspect of the invention, the vehicle information collecting device temporarily stores the traveling locus in the vehicle locus storage unit when the vehicle determining unit determines that the traveling locus does not match the road map information. Therefore, a part of the processing of the traveling locus that does not match the road map information can be performed by the vehicle information collection device, and the burden on the map information device can be reduced. This also reduces the equipment cost of the map information processing device.
[0017]
According to the fourth aspect of the present invention, when the travel locus calculated by the locus calculation means and the travel locus temporarily stored in the vehicle locus storage means match a plurality of times, the travel locus is transmitted to the map information processing apparatus by the communication means, so that the map information is transmitted. There is no need to sequentially transmit information to the device for processing, and the processing of the map information device is reduced. In addition, since the traveling locus that the traveling locus temporarily stored on the vehicle side matches a plurality of times is transmitted, the reliability of the information is improved.
[0018]
According to the invention described in claim 5, when the traveling directions of the traveling locus coincide with each other a plurality of times, it can be determined that the road is a one-way road that can only pass in the traveling direction. Judge and update. Therefore, it is possible to update the road map information at a very low cost without spending any manpower on whether the road is one-way.
[0019]
According to the invention described in claim 6, when the time when the vehicle travels along the traveling locus does not exist in an arbitrary time zone, it can be determined that the road is a time-regulated road that cannot pass in that time zone. The updating means determines that the road has time restrictions and updates the road. Therefore, it is possible to update the road map information at a very low cost without spending any manpower on whether or not the road is a time-regulated road.
[0020]
In the invention described in claim 7, the width intervals of the positions of the traveling trajectories for each traveling direction, the width intervals of the traveling trajectories of the same vehicle at different times in the same traveling direction, the vehicle speed regulated by the road width, and the vehicle running at the same time The width of the road is determined from the locus position of the vehicle to be updated, and the updating unit updates the road width. Accordingly, the road map information can be updated at a very low cost without spending labor on the road width.
[0021]
According to the invention described in claim 8, a plurality of traveling trajectories satisfying the road width in a certain traveling direction are determined from the traveling direction, the time information, the vehicle speed information, and the road width determined by the updating unit from the traveling information from the vehicle information collecting device. If the vehicle is present and the vehicle speed is very low, it is determined that the vehicle is suddenly congested and transmitted to the vehicle as congestion information. Therefore, even on a road where information cannot be obtained by the road traffic information communication system, smooth traffic can be performed by obtaining this congestion information.

[0053]
In step S402, processing related to sudden congestion is performed. Details will be described later.
[0054]
[Detection of new roads / change of road map]
In the vehicle map processing system according to the present embodiment, conventionally, when a road C1 running parallel to an existing road B1 is completed and the vehicle A1 passes, the map matching does not determine that the road is a new road. Therefore, the vehicle A1 equipped with the vehicle information collection device 1 will pass many times. The vehicle information collection device 1 always performs the processing shown in FIG. 3 at predetermined time intervals during traveling. That is, the position information indicating the vehicle positions at a plurality of points indicating the traveling locus is detected by the position detection unit 11 of the vehicle information collection device 1 and stored in the position information storage unit 12. This is performed in step S101.
[0055]
Next, the position information traveling on the road C1 running parallel to the existing road B1 is compared with the position information of the existing road in the road map information storage unit 16, but does not match. This is determined in step S103.
When the position information traveling on this new road is detected for the first time, the position information is stored in the position information temporary storage unit 13.
[0056]
At this time, the process proceeds from step S110 to step S111, so that the map matching is performed, and as in the conventional case, it is displayed as if the vehicle is running on an existing road as shown in FIG. It will be.
When the same vehicle travels on the new road a plurality of times again, the position information coincides with the position information temporarily stored in the position information temporary storage unit 13. This is determined in step S105 and counted in step S106. In this way, when the predetermined number of times is reached, the position information is transmitted to the server 2 and the position information indicating the road map data stored and stored in the road map information storage unit 16 of the vehicle information collection device 1. Is updated to add this location information. Therefore, after performing this processing, map matching is performed in step S111, so that the new road is written on the displayed map as shown in FIG. 5B, and the vehicle is running on the new road C2. Will be displayed.
In the present embodiment, by performing such processing before the map matching processing, it is possible to reliably detect a road that runs parallel to an existing road.
[0057]
Also, a large number of position information indicating that a new road has been detected a predetermined number of times is sent to the server 2 installed at a predetermined place.
The first one of them does not match the existing road position information and does not match the position information in the server position information temporary storage unit 22 in the judgments of steps S203 and S205 in FIG. This is temporarily stored in the position information temporary storage unit 22.
Since a plurality of other vehicles equipped with the vehicle information collecting device 1 pass on the new road, a plurality of pieces of this position information are sent, and the position information is temporarily stored in the server position information. It will match the position information of the unit 22 a plurality of times. When this reaches a predetermined number of times, position information indicating a new road is added to the road map data in the server road map information storage unit 23.
[0058]
The road map information in the server road map information storage unit 23 is distributed to the vehicle periodically or as needed, or is acquired by a request from the vehicle.
With this configuration, a new road that runs alongside an existing road is detected, and the vehicle information collection device 1 of another vehicle is detected while displaying the new road on the display of the navigation device of the vehicle. Will automatically update the road map information including the new road detected in step (1).
[0059]
[Control of manpower and costs]
In the present embodiment, information of a new road is automatically added, so that investigation and measurement of a new road and update work of road map information can be omitted, so that manpower and costs are greatly reduced. Further, by performing the update as described below, the work of investigating and measuring the road and updating the road map information can be further omitted, and the manpower and cost can be greatly reduced.
These determinations may be made by either the comparison / determination unit 14 of the vehicle information collection device 1 or the server comparison / determination unit 21 of the server 2.
[0060]
(1) One-way decision
When the traveling direction 32 included in the position information 3 is only one direction in the plurality of pieces of information, the road is updated as a one-way road. Therefore, the labor and cost for one-way investigation and registration can be saved.
[0061]
(2) Judgment of time regulation
When the traveling time 33 included in the position information 3 indicates that there is no traffic only in a certain time zone, the road is updated as a time-regulated road. Therefore, the labor and cost for investigating and registering whether there is a time restriction can be saved.
[0062]
③ Decision of road width
From the vehicle position 31, the traveling direction 32, the time 33 at that position, and the vehicle speed 34 included in the position information 3, the vehicle positions arranged in the same traveling direction or the vehicles arranged in the same direction at different times of the same vehicle The road width is determined and updated based on the position and the vehicle speed restricted by the road width. Therefore, labor and cost for the survey and registration of the road width can be saved.
[0063]
[Server load reduction effect]
In the vehicle map processing system according to the present embodiment, the position information detected by the position detection unit 11 of the vehicle information collection device 1 is not sent to the server 2 in that state, but the road map information storage unit of the vehicle information collection device 1 is used. 16 is compared with the position information in the position information temporary storage unit 13 to determine that the road is a new road a predetermined number of times before sending it to the server 2. Can be determined from the determination as to whether or not a plurality of vehicles are used. As described above, since part of the processing is performed on the vehicle side, the load on the server 2 becomes light.
[0064]
[Transport smoothing effect]
FIG. 7 is a flowchart showing the flow of the congestion information processing executed by the server 2 of the embodiment. Each step will be described below. Steps S411 to S416 shown in FIG. 7 are processed in step S402 in FIG.
[0065]
In step S411, the congestion information is called from the server location information temporary storage unit 22.
[0066]
In step S412, it is determined whether or not the congestion information acquired from the vehicle information collection device 1 and the congestion information called from the server location information temporary storage unit 22 match. If they match, the process proceeds to step S413, and if not, Moves to step S416.
[0067]
In step S413, the number of times of congestion information determined to match in step S412 is counted.
[0068]
In step S414, it is determined whether or not the count in step S413 reaches a predetermined number. If the count has reached the predetermined number, the process proceeds to step S415, and if not, the process proceeds to step S202. .
[0069]
In step S415, a plurality of congestion information is aggregated and transmitted to the vehicle.
[0070]
In step S416, the congestion information is stored in the server location information temporary storage unit 22.
[0071]
In the present embodiment, when the comparison determination unit 14 of the vehicle information collection device 1 determines sudden congestion from the vehicle position 31, the direction 32, the time 33, the vehicle speed 34, and the position information including the road width determined from these. The position information is sent to the server 2 as congestion information in steps S301 and S302 in FIG. As a result, when sudden congestion occurs on the road, the congestion information is sent from the vehicle information collection device 1 of a plurality of vehicles located there, so that the server 2 can determine the detailed situation in step S401. In this case, it is determined in step S414 that the congestion information indicating the same congestion state has a predetermined amount of data, and in that case, information obtained by consolidating the congestion information is stored in a nearby vehicle by the processing in step S415. The transmission is useful for other vehicles to avoid sudden congestion, and for vehicles involved in sudden congestion to grasp the situation. Therefore, even in a place where the traffic information by the road traffic information communication system cannot be obtained, the information from the vehicle is aggregated and distributed, which is useful for smooth traffic.
[0072]
Next, effects will be described.
[0073]
In the vehicle map processing system of the embodiment, the following effects can be obtained.
[0074]
(1) The vehicle is provided with a vehicle information collection device 1 including a comparison and determination unit 14 that calculates position information that is a traveling locus of the vehicle from the vehicle position information and the road map information, and a communication processing unit 18 that communicates with the outside. A server communication processing unit 24 that communicates with the vehicle information collection device 1; a server position information temporary storage unit 22 that temporarily stores position information from the vehicle information collection device 1 that does not match the road map information; A server comparison / judgment unit 21 that at least compares and judges whether the position information from the vehicle information collecting device 1 obtained by the communication processing unit 24 substantially matches the position information in the server position information temporary storage unit 22 or the road map information. The server road map information storage unit uses the position information as a new road when the position information substantially matches the traveling locus of the server position information temporary storage unit 22 a plurality of times based on the comparison judgment of the server comparison judgment unit 21. Since the server 2 comprising updating means for updating the position information 3 is provided outside the vehicle, and the vehicle information collecting apparatus 1 and the server 2 constitute a vehicle map processing system, the existing system can be used without spending manpower and costs as in the prior art. A new road adjacent to the road can be detected, and the road map information can be updated.
[0075]
(2) Since the vehicle information collecting apparatus 1 compares and judges whether or not the calculated position information and the road map information match, the load on the server 2 can be reduced, and the equipment of the server 2 can be reduced. Costs can be reduced.
[0076]
(3) Since the vehicle information collecting apparatus 1 has the position information temporary storage unit 13 for temporarily storing the position information when the comparison and determination unit 14 determines that the position information does not match the road map information, the server 2 can be reduced, and the equipment cost of the server 2 can be reduced.
[0077]
(4) When the calculated position information matches the position information temporarily stored in the position information temporary storage unit 13 a plurality of times, the comparison processing unit 14 of the vehicle information collection device 1 transmits the traveling locus to the server 2 by the communication processing unit 18. Therefore, the processing of the server 2 can be reduced, and the reliability of the information is improved.
[0078]
(5) The position information includes information indicating the traveling direction, and the server comparison / determination unit 21 of the server 2 determines that the position information from the vehicle information collection device 1 is the same as the position information of the server position information temporary storage unit 22. When the location information matches multiple times and the traveling direction of the location information matches multiple times, it is determined that the road is a one-way street and updated, so the cost is greatly reduced without any additional manpower. Can be updated.
[0079]
(6) The position information includes time information when the vehicle travels along the locus, and the server comparison / determination unit 21 of the server 2 stores the position information from the vehicle information collection device 1 in the server position information temporary storage unit 22. If the location information substantially matches the location information a plurality of times and the time when the location information travels does not exist in an arbitrary time zone, it is determined that the road is time-restricted and updated, so more manpower is required. The road map information can be updated at a very low cost without much cost.
[0080]
(7) It is assumed that the position information includes the traveling direction, time information when traveling along the locus, and vehicle speed information, and the server comparison / determination unit 21 of the server 2 determines the traveling direction, time information, and vehicle speed information of the position information. Since the road map information is updated by judging the road width, the road map information can be updated at a very low cost without further labor.
[0081]
(8) The server 2 detects sudden running congestion from the traveling direction, time information, vehicle speed information, and road width determined by the updating means of the position information from the vehicle information collecting device 1 and transmits congestion information to the vehicle. Therefore, even on a road on which information cannot be obtained by the road traffic information communication system, traffic can be smoothly obtained by obtaining this congestion information.
