Description

  The present invention relates to a map information generation technique, and more particularly, to a system for updating map information that informs an installation location of a charging facility (plug-in station) of a hybrid vehicle or an electric vehicle based on probe information.

  In recent years, electric vehicles and plug-in hybrid vehicles have become popular from the viewpoint of environmental protection. These automobiles have a great merit that they are more energy efficient than conventional gasoline cars and do not generate carbon dioxide when traveling.

  Since electric vehicles and plug-in hybrid vehicles use electricity as their power, a facility (plug-in station: PIS) for charging the mounted battery is required. Such a charging facility is similar to a conventional gas station. No major equipment is required. For this reason, it is relatively easy to install it in supermarkets, convenience stores, or parking lots in towns, and it is expected that it will enter the charging service provision business from various industries in the future.

  As business entry from a variety of industries becomes popular, the possibility of frequent new installations of charging facilities will increase, and on the other hand, the frequency of removal of existing charging facilities will increase. For the map information provider, it is important to provide the user with accurate information such as the installation location of the charging facility by frequently updating the map information.

  Conventionally, gasoline vehicles and diesel vehicles have been the mainstream, and the refueling place for these vehicles has been gas stations, and the cycle of opening and closing new stores has been relatively long. Therefore, there is no such inconvenience even if the cartographer collects information about the location of the gas station at a relatively long period of time and reflects the information on the map. In addition to being a relatively large facility, gas stations are often located along high-traffic roads, so even if they are not listed on the map provided to users, It is easy to catch the eyes of the driving user.

  On the other hand, in the case of charging facilities for electric vehicles and plug-in hybrid vehicles, the situation is greatly different. That is, when new installations of these charging facilities are frequently performed, it is difficult to provide accurate information such as the installation location of the charging facility to the user side by updating the map data by the conventional method. It is. That is, a person who provides map information is required to provide accurate information to the user by frequently updating information on the installation location of the charging facility.

  In addition, supermarkets, convenience stores, and parking lots in towns that are expected to be places where charging facilities are installed are not necessarily places that are easily noticed by users who drive automobiles. The size of is just a thing that is easy to miss. Therefore, the accuracy of the map information becomes important for a user who needs to find a charging facility based on the provided map information.

  One effective method for collecting map information is the probe car system. According to the probe car system, information is collected using an automobile as a sensor, information collected by the automobile is sent to the center together with GPS position information, and information such as road conditions is timely based on the information. It can be provided to the user.

  For example, Japanese Patent Laying-Open No. 2005-62854 (Patent Document 1) generates current road information of content in a road map from probe information of a probe car, and on-map road information and current road information associated with the road map regarding the content. When the two are different from each other, and the two are different, the content is manifested on the road map, or the road information on the map is replaced with the current road information, so that the content of the road map is automatically An invention of a method for enabling updating is disclosed.

  Japanese Patent Laying-Open No. 2008-164831 (Patent Document 2) discloses an invention of a map information generation system that generates new road information related to a new road to be added to map information stored in a navigation device or the like. Yes. In this invention, the travel locus information when the probe car travels on a road not included in the navigation map data included in the navigation device is transmitted as probe data to the map distribution center, while the travel locus information is transmitted from the navigation device of each vehicle. The map distribution center that has received is configured to collect the received data and further narrow down the target data by excluding the travel locus information that the vehicle is predicted not traveling on the new road. Yes.

  All of these inventions use a probe car as a means for collecting road information. However, the road information is merely information about the road itself, and does not include information that associates the driving route of the vehicle with various facilities. In other words, depending on the invention disclosed in the above prior art documents, the user can obtain location information of facilities that are expected to be frequently installed or removed, such as charging facilities for electric vehicles and plug-in hybrid vehicles. Cannot provide information accurately.

This is transmitted as probe information to the provided center device (probe server) 300.

  The center device 300 receives the PIS information from the in-vehicle device 200 mounted on the user vehicle that is a probe car, and receives the PIS information and map information that indicates the installation location of the plug-in station generated based on the PIS information. The map information is stored as data, and is further distributed to the in-vehicle device 200 of the user vehicle via the network 100.

  FIG. 2 is a block diagram for explaining the outline of the configuration of the map information generation system according to the first aspect of the present invention.

  The PIS information transmission device 400 is provided at a place where a charging facility (plug-in station) is installed, and includes a transmission unit 410 and a PIS information storage unit 420 that stores the above-described PIS information including point information of the charging facility.

  The in-vehicle device 200 includes a PIS information receiving unit 210 that receives the PIS information from the PIS information transmission device 400, a receiving unit 220 that receives distribution of map information from the center device 300, and a PIS that stores the received map information as data. A map storage unit 230, a PIS information reference unit 240 for updating the map information stored in the PIS map storage unit 230 to the latest one, and a transmission unit 250 that transmits the PIS information to the center apparatus 300 as probe information. It has.

  The PIS information reference unit 240 is not essential for the map information generation system of the present invention, and the in-vehicle device 200 can be configured without the PIS information reference unit 240 illustrated in FIG. However, the PIS information reference unit 240 refers to the PIS information received from the PIS information transmission device 400 to the map information stored in the PIS map storage unit 230, and when the PIS information is unregistered, the PIS information is newly updated. Since it has a function of updating the map information stored in the PIS map storage unit 230 by registering as PIS information of a new plug-in station, it does not wait for delivery of the latest map information from the center device 300. There is an advantage that map information can be quickly updated in a vehicle.

  The in-vehicle device 200 includes a user information storage unit 260 that stores user information associated with the in-vehicle device 200 as data, and the user information is transmitted to the center device 300 together with the probe information described above. Also good.

  Here, the user information is, for example, user ID or electronic signature information. This user information can also be used for the purpose of ensuring the reliability of the probe information transmitted to the center apparatus 300.

  The center apparatus 300 receives probe information (and user information) transmitted from the in-vehicle apparatus 200 by the receiving unit 310. The PIS information comparison / determination unit 320 refers to the probe information to the map information stored in the probe information storage unit 330, and the point information included in the probe information is not registered in the current map information. The PIS information including the unregistered point information is registered as the PIS information of the new plug-in station and updated as the latest map information.

      FIG. 3 is a diagram for explaining the update of the map information described above by way of example.

  FIG. 3A is a navigation image provided to the user based on the map information stored in the PIS map storage unit 230 of the in-vehicle device, and the point indicated by the plug mark in this image is the charging facility. It is an installation place.

  It is assumed that the user has charged at a charging facility provided in a certain place. As described above, the PIS information transmission device 400 including the PIS information storage unit 420 is provided at the installation site of the charging facility, and the charging facility is connected via a communication cable provided in the charging cable during charging. PIS information related to the charging facility is transmitted to the in-vehicle device 200 to the in-vehicle device 200 of the user vehicle.

  As a result of the PIS information reference unit 240 provided in the in-vehicle apparatus 200 referring to the map information stored in the PIS map storage unit 230, the PIS information is currently stored in the PIS map storage unit 230. If the map information is unregistered, as shown in FIG. 3B, the position of the unregistered charging facility is indicated by a star on the map.

  Since the user can know from the navigation image that the map information stored in the PIS map storage unit 230 is not the latest, the user updates the map information after confirming this. In the updated navigation image, a plug mark is displayed at the position indicated by the star in FIG. 3B, and it is displayed that the charging facility is installed at the point (FIG. 3). (C)) Update of the map information performed on the center device 300 side is also performed by the same procedure.

  Note that, as described above, the PIS information reference unit 240 is not essential for the in-vehicle device 200, and the map information in the vehicle is not updated if the PIS information reference unit 240 is not provided. Therefore, the navigation image shown in FIG. 3C is obtained only after receiving the latest map information distribution after the update on the center device 300 side.

  Since the provision of probe information as described above is performed by many users of electric vehicles and plug-in hybrid vehicles, the map information distributed from the transmission unit 340 to the in-vehicle device is frequently updated. The user can always search for a charging facility based on the latest information.

  The map information generation system according to the present invention may have various variations in addition to the above-described aspect (first aspect). For example, in the first aspect, the probe information is provided every time the user performs charging, but this may cause an adverse effect that the frequency of communication between the in-vehicle device 200 and the center device 300 increases more than necessary. . Therefore, there may be a mode in which the amount of communication of the entire system is limited to an appropriate level by transmitting probe information at regular intervals.

  FIG. 4 is a block diagram for explaining the outline of the configuration of the map information generation system according to the second aspect of the present invention. In this aspect, the PIS information received from the PIS information transmission apparatus 400 in the in-vehicle apparatus 200. Is stored as charge history data, and the charge history data is transmitted to the center apparatus 300 as probe information at regular intervals.

  In order to improve the reliability and accuracy of the map information generation system according to the present invention, when updating the map information on the probe information center side, whether the reliability and accuracy of the probe information is evaluated and registered as new PIS information It is preferable to determine whether or not. That is, the PIS information comparison / determination unit 320 provided in the map information generation system according to the first and second aspects is allowed to evaluate and judge the reliability and accuracy of the probe information, The map information generation system according to the third and fourth aspects may be used.

  The reliability and accuracy of unregistered PIS information is, for example, the point information included in the unregistered PIS information matches the unregistered point information extracted based on a plurality of probe information transmitted from a plurality of in-vehicle devices. You may make it evaluate by criteria, such as whether to do.

  In this case, in the PIS information comparison / determination unit 320, the spot information extracted as unregistered in the map information matches the unregistered spot information extracted based on the plurality of probe information transmitted from the plurality of in-vehicle devices. In this case, the probe information is registered as PIS information of a new charging facility. In addition to the above method, the reliability of the probe information may be ensured by confirming the electronic certificate included in the PIS information.

  Further, whether or not the charging facility is a private property may be added to the registration determination of the unregistered PIS information. If the charging facility is a private property, it is not necessary or desirable that the charging facility is included in the publicly distributed map information. On the other hand, as described above, owner information can be included in the PIS information.

  Therefore, if the determination unit (not shown) provided in the PIS information comparison / determination unit 320 rejects registration as new PIS information when the charging facility is private, the charging facility that is private. Can be prevented from being included in the map information.

  Any of the map information generation systems according to the above-described aspects uses PIS information that is provided at a charging facility installation location and includes point information of the charging facility. In the map information generation system of the aspect described below, a change in the remaining battery level of an automobile equipped with an in-vehicle device is used instead of the PIS information.

  FIG. 5 is a block diagram for explaining the outline of the configuration of the map information generation system according to the fifth aspect of the present invention. Also in this aspect, the basic configuration of the center apparatus 300 is the same as that in the first to fourth aspects described above.

  The in-vehicle device 200 includes a battery monitor 290 that measures the remaining amount of the battery 280 of the own vehicle. The receiving unit 220 receives the distribution of the map information from the center apparatus 300, and this map information is stored as data by the PIS map storage unit 230. The remaining battery level measured by the battery monitor 290 is sent from the transmission unit 250 to the center apparatus 300 as probe information together with the travel history information (point information and time information) recorded in the travel history information storage unit 270.

  As in the first to fourth aspects described above, the in-vehicle device 200 is further provided with a user information storage unit 260 that stores user information associated with the in-vehicle device 200 as data. You may make it transmit user information to the center apparatus 300 with the above-mentioned probe information.

  The center device 300 receives probe information (battery remaining amount information, travel history information, and user information) transmitted from the in-vehicle device 200 by the receiving unit 310.

  The PIS information comparison / determination unit 320 extracts the spot information of the installation location of the charging facility based on the probe information transmitted from the in-vehicle device 200, and refers to the map information stored in the probe information storage unit 330. . And when the extracted point information is unregistered in map information, the said point information is registered as an installation place of a new charging facility, and map information is updated.

  At the time of registration, the map information may be updated with the point information for which the registration determination is made after determining in advance whether or not to register the unregistered point information as a new charging facility installation location. Good. Prior judgments made prior to registration are made under the responsibility of the manager (provider of map information), so that the reliability and accuracy of the latest map information provided to the user can be improved.

  FIG. 6 is a diagram for explaining, by way of example, a method for extracting point information of the installation location of the charging facility based on the probe information. FIG. 6A is a navigation image provided to the user based on the map information stored in the probe information storage unit 330 of the center apparatus 300, and the point indicated by the plug mark in this image is the charging facility. This is the installation location.

  Assume that the travel history of the user vehicle is as shown in FIG. As shown in FIG. 6C, the remaining battery level gradually decreases during traveling from point A to point D. When this user finds a charging facility at point D and uses the charging facility, the remaining battery level is lost due to charging. As the amount increases and the vehicle is stopped during the charging operation, the remaining battery level at point D increases rapidly in a staircase pattern. When the vehicle departs after charging and travels from point E to G, the remaining battery level gradually decreases.

  The PIS information comparison / determination unit 320 provided in the center device 300 that has received the probe information has a charging facility at the point D due to a steep increase in the remaining battery level as at the point D in FIG. Judge that there is. That is, the presence / absence of the charging facility is determined from the remaining battery information included in the probe information. Then, the point information of the charging facility is extracted and referred to the map information stored in the probe information storage unit 330.

  As a result of this reference, if the extracted spot information is not registered in the map information, it is determined whether or not the spot information is to be registered as a new plug-in station installation location, and a registration judgment is made. Update map information with point information. In the updated navigation image, a plug mark is displayed at the position of the point D, and it is displayed that a charging facility is installed at the point (FIG. 6D).

  In addition, the said registration judgment is the unregistered spot information from which the above-mentioned unregistered spot information was extracted based on the several probe information transmitted from the several vehicle-mounted apparatus similarly to the 3rd and 4th aspect, for example. May be performed based on a criterion such as whether or not they match.

  In the map information generation system of the fifth aspect, it is not only unnecessary that the charging facility is included in the publicly distributed map information when the charging facility is privately owned. Not that.

  Therefore, for example, it is determined from the location information included in the PIS information whether or not the charging facility is installed in a residential area, and the charging facility installed in the residential area is determined to be private. If the registration as new PIS information is rejected, it is possible to avoid the charging facility which is a private property from being included in the map information.

  FIG. 7 is a block diagram for explaining an outline of the configuration of the map information generation system according to the sixth aspect of the present invention. A charge history information storage unit 265 is provided in the in-vehicle device 200. Except for the point that data is transmitted to the center apparatus 300 as probe information at regular intervals, it is the same as that of the map information generation system of the fifth aspect, and repeated description is omitted.

  So far, only the new registration of the PIS information of the charging facility has been described, but the map information generation system of the present invention is configured to provide the user with accurate information by deleting the registered PIS information from the map information. It is also possible.

  Charging facilities for electric vehicles and plug-in hybrid vehicles are expected to be newly installed frequently, and at the same time, it is expected that facilities will be frequently removed due to relocation and withdrawal from charging services. The Once the charging facility associated with the PIS information registered as the map information has already been removed for some reason, if the PIS information of the charging facility is left in the map information, it is accurate for the user. It becomes impossible to provide information.

  Therefore, for example, every time the charging facility is used, the PIS information of the charging facility is distributed from the in-vehicle device 200 to the center device 300 regardless of whether or not the PIS information of the charging facility is registered in the map information. To ensure the accuracy of the map information provided to the user by recording the distribution history and listing the PIS information of the charging facility that has not been used for a predetermined period as a target for deletion. It is also possible to do.

  As described above, in the present invention, an electric vehicle or a plug-in hybrid vehicle, which is a general vehicle, is used as a probe car, and information associated with a charging facility is transmitted to the center device every time these vehicles are charged. I did it.
