Description

  The present invention relates to an FCD in-vehicle device that acquires the position of a host vehicle from in-vehicle devices and in-vehicle sensors mounted on a vehicle and transmits probe information including position information indicating the position of the host vehicle to a probe information collection center, and the FCD in-vehicle device. The present invention relates to a probe information collection system including a probe information collection center that receives probe information transmitted from a machine, and an FCD in-vehicle machine used in the probe information collection system.

  In the probe information collection system, in an FCD (floating car data) onboard device mounted on a vehicle, for example, a position that represents the position of the vehicle by acquiring the vehicle position from a GPS receiver or a navigation device every certain period of time. Probe information including information is transmitted to the probe information collection center.

  By the way, in business vehicles such as buses and taxis, there are cases where the vehicle travels or stands by in the premises of a rotary or business office, for example, in front of a station. For this reason, in business vehicles such as buses and taxis, as described above, the position where the vehicle position is acquired every certain period of time and the position information indicating the position of the vehicle is transmitted to the probe information collection center is meaningless. Position information is transmitted to the probe information collection center, and there is a problem that extra communication costs are generated.

On the other hand, the following Patent Document 1 describes a configuration in which a navigation apparatus receives traffic jam statistical information created at a traffic information center and superimposes it on a map.
JP 2003-302229 A

  However, what is described in the above-mentioned Patent Document 1 has not yet solved the problem of transmitting probe information including useless position information as described above to the probe information collection center.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to avoid transmitting probe information including useless position information to the probe information collection center. An object of the present invention is to provide a probe information collection system and an FCD in-vehicle device that can avoid the occurrence of unnecessary communication costs.

According to the probe information collection system described in claim 1, the probe information collection center notifies the FCD vehicle-mounted device of an area where the vehicle is not substantially operating as a specific area, and the FCD vehicle-mounted device is a probe information collection center. When a specific area is notified from the vehicle, it is determined whether or not the road attribute of the vehicle position added to the link information that has been map-matched by the navigation device corresponds to the road attribute notified from the probe information collection center. In this way, it is determined whether the vehicle position is within or outside the singular area notified from the probe information collection center. When the FCD in-vehicle device detects that the vehicle position is outside the singular area, it transmits probe information including position information indicating the vehicle position to the probe information collection center, while the vehicle position is in the singular area. If it is detected that the vehicle is within the range, the probe information including the position information indicating the vehicle position is not transmitted to the probe information collection center.

  As a result, when the FCD in-vehicle device is mounted on a business vehicle such as a bus or taxi, for example, the rotary in front of the station or the premises of the sales office is set as a specific area, so that the rotary or business in front of the station etc. If it is an area other than the premises of the site (area that is actually operating), probe information including position information indicating the position of the vehicle will be sent to the probe information collection center, while the station front etc. If it is an area within the premises of a rotary or sales office in Japan (an area that does not operate substantially), probe information including position information indicating the position of the vehicle will not be transmitted to the probe information collection center. Transmission of probe information including unnecessary position information to the probe information collection center can be avoided, resulting in unnecessary communication costs. It would a can be avoided in advance.

According to the probe information collection system described in claim 2 , the FCD in-vehicle device determines whether the map matching in the navigation device is correct or not, and if the map matching is detected to be positive, the map matched link in the navigation device It is determined whether the road attribute of the own vehicle position added to the information corresponds to the road attribute notified from the probe information collection center. Probe information including positional information to be represented is not transmitted to the probe information collection center.

  Thereby, even when the map matching in the navigation device is not possible, it is possible to prevent the probe information including the position information indicating the vehicle position from being transmitted to the probe information collection center.

According to the FCD in-vehicle device described in claim 3 , an area where the vehicle is not substantially operating is notified as a specific area from the probe information collection center, and is added to the link information that is map-matched by the navigation device. By determining whether the road attribute of the vehicle position corresponds to the road attribute notified from the probe information collection center, the vehicle position is within or outside the singular area notified from the probe information collection center. Determine if there is. When detecting that the vehicle position is outside the singular area, probe information including position information indicating the vehicle position is transmitted to the probe information collection center, while the vehicle position is within the singular area. If detected, probe information including position information indicating the position of the vehicle is not transmitted to the probe information collection center.

  Accordingly, it is possible to avoid transmitting probe information including useless position information and the like to the probe information collection center in the same manner as described in claim 1 above, and extra communication cost. Can be avoided in advance.

In this case, the probe information collection center 4 is commissioned by, for example, a bus operating company or the like and collects bus position information as probe information.

  The FCD in-vehicle device 3 includes a communication device 5 that performs a communication operation with the probe information collection center 4 and a GPS receiver that receives a GPS radio wave transmitted from a GPS satellite (not shown) and calculates its own vehicle position. 6 and a control device 7 that controls the communication device 5 and the GPS receiver 6. In the above configuration, the probe information collection center 4 and the FCD in-vehicle device 3 are in a one-to-n (plural) relationship, that is, the probe information collection center 4 supervises the operation management of a plurality of buses. is there.

Next, the operation of the above configuration will be described with reference to FIG.
First, the probe information collection center 4 transmits a specific area to the FCD in-vehicle device 3 (step S1). Here, the singular area is an area corresponding to the site of a rotary or business office in front of the station, for example, which is notified in advance by the bus operator. In this case, the site of the rotary or business office in front of the station, etc. For example, it is a closed area represented by a predetermined radius centered on latitude and longitude coordinates. Further, for example, because of the fact that the sites of the rotary and the sales office are different for each bus route, the specific area may be different for each bus route.

  In the FCD in-vehicle device 3, when the control device 7 detects that the unique area transmitted from the probe information collection center 4 has been received by the communication device 5 ("YES" in step T1), the received unique area (Closed area) is stored (step T2). When the control device 7 detects that the vehicle position acquisition timing set in advance for every predetermined time has elapsed (“YES” in step T3), the control device 7 issues a vehicle position acquisition request to the GPS receiver 6. To wait for the vehicle position to be input from the GPS receiver 6 (step T4).

  When the control device 7 detects that the vehicle position is input from the GPS receiver 6 (“YES” in step T4), the latitude and longitude coordinates of the input vehicle position are stored in advance. By determining whether the vehicle is within the closed area or outside the closed area, it is determined whether the vehicle position is within the singular area or outside the singular area (step T5).

  When the control device 7 detects that the latitude / longitude coordinates of the vehicle position are outside the closed area and detects that the vehicle position is outside the singular area ("YES" in step T5), the control device 7 Probe information including position information representing the position is transmitted from the communication device 5 to the probe information collection center 4 (step T6), the process returns to the above-described step T3, and the above-described processing is repeated. In response to this, when the probe information collection center 4 detects that the position information transmitted from the FCD in-vehicle device 3 is received in this way ("YES" in step S2), the received position information Is stored in the database (step S3), and thereafter, valid information necessary for bus operation management is created.

  On the other hand, when the control device 7 detects that the latitude and longitude coordinates of the vehicle position are within the closed area and detects that the vehicle position is within the singular area ("NO" in step T5), the control device 7 Without transmitting the probe information including the position information indicating the position from the communication device 5 to the probe information collection center 4, the process returns to the above-described step T3 and the above-described processing is repeated.

  As described above, according to the first embodiment, in the FCD in-vehicle device 3, the latitude and longitude coordinates of the vehicle position acquired from the GPS receiver 6 are within the closed area notified from the probe information collection center 4. By determining whether the vehicle position is within the singular area or outside the singular area by determining whether the vehicle is outside the closed area, Probe information including position information indicating the position is transmitted to the probe information collection center 4. On the other hand, when it is detected that the own vehicle position is within the singular area, probe information including position information indicating the own vehicle position is probed. The information collection center 4 is not transmitted.

  As a result, for example, the area of the rotary or sales office in front of the station is set as a closed area, so that the area other than the area of the rotary or sales office in front of the station (area that is actually operating) For example, probe information including position information indicating the position of the host vehicle is transmitted to the probe information collection center 4. ), Probe information including position information indicating the position of the vehicle is not transmitted to the probe information collection center 4, so probe information including useless position information is transmitted to the probe information collection center. This can be avoided in advance, and the occurrence of unnecessary communication costs can be avoided in advance.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. In addition, description is abbreviate | omitted about the same part as above-mentioned 1st Embodiment, and a different part is demonstrated. In the first embodiment described above, the FCD in-vehicle device 3 determines whether the latitude / longitude coordinate of the vehicle position acquired from the GPS receiver 6 is within the closed area or outside the closed area, thereby In contrast to this, the second embodiment is added to the link information in which the FCD in-vehicle device is map-matched by navigation. By determining whether the road attribute of the current vehicle position corresponds to the road attribute notified from the probe information collection center 4, it is determined whether the vehicle position is within the singular area or outside the singular area It is the structure to do.

  That is, in the probe information collection system 11, the FCD in-vehicle device 12 includes a communication device 13 that performs a communication operation with the probe information collection center 4, a navigation device 14 that has a positioning function using, for example, a GPS receiver or a gyro, The communication device 13 and the control device 15 for controlling the navigation device 14 are provided.

Next, the operation of the above configuration will be described with reference to FIG.
First, the probe information collection center 4 transmits a specific area to the FCD in-vehicle device 12 (step S11). Here again, the singular area is the area corresponding to the premises of the rotary or sales office in front of the station, for example, which is notified in advance by the bus operator. A road attribute representing an area excluding the site. It is assumed that this road attribute is compatible with the road attribute that the map data of the navigation device 14 has.

  In the FCD in-vehicle device 12, when the control device 15 detects that the singular area transmitted from the probe information collection center 4 has been received by the communication device 5 ("YES" in step T11), the received singular area. (Road attribute) is stored (step T12). Then, when the control device 15 detects that the vehicle position acquisition timing set in advance every predetermined time has passed (“YES” in step T13), the control device 15 sends a vehicle position acquisition request to the navigation device 14. It outputs and determines the right or wrong of the map matching in the navigation apparatus 14 (step T14).

  Here, when the control device 15 detects that the map matching in the navigation device 14 is positive (“YES” in step T14), the own vehicle added to the link information map-matched in the navigation device 14 It is determined whether the road attribute of the position corresponds to the previously stored road attribute, and it is determined whether the vehicle position is within the singular area or outside the singular area (step T15).

  And the control apparatus 15 detects that the road attribute of the own vehicle position corresponds to the road attribute notified from the probe information collection center 4, and detects that the own vehicle position is outside the singular area (in step T15). "YES"), the probe information including the position information indicating the position of the vehicle is transmitted from the communication device 13 to the probe information collection center 4 (step T16), the process returns to the above step T13, and the above process is repeated. . In response to this, in this case as well, when the probe information collection center 4 detects that the position information transmitted from the FCD in-vehicle device 12 is received in this way ("YES" in step S12), the reception is performed. The stored position information is stored in a database (step S13), and thereafter, effective information necessary for bus operation management is created.

  On the other hand, the control device 15 detects that the map matching in the navigation device 14 is not possible ("NO" in step T14), or the road attribute of the vehicle position is notified from the probe information collection center 4. When it is detected that the vehicle does not correspond to the road attribute, and the vehicle position is detected to be within the singular area (“NO” in step T15), probe information including position information indicating the vehicle position is transmitted from the communication device 13. Without transmitting to the probe information collection center 4, the process returns to the above-described step T 13 and the above-described processing is repeated.

  As described above, according to the second embodiment, in the FCD in-vehicle device 12, the road attribute of the vehicle position added to the link information map-matched by the navigation device 14 is obtained from the probe information collection center 4. By determining whether or not the road attribute is informed, it is determined whether the vehicle position is within the singular area or outside the singular area, and detecting that the vehicle position is outside the singular area Probe information including position information representing the vehicle position is transmitted to the probe information collection center 4. On the other hand, if it is detected that the vehicle position is within the singular area, the probe includes position information representing the vehicle position. The information is not transmitted to the probe information collection center 4.

  As a result, for example, the area other than the rotary in the station and the area other than the premises of the sales office is set as a road attribute, so that the rotary or the station in front of the station or the like is the same as that described in the first embodiment. If it is an area excluding the site of the sales office, probe information including location information indicating the position of the vehicle will be transmitted to the probe information collection center 4, while it is within the site of the rotary or sales office in front of the station. In this area, probe information including position information indicating the position of the vehicle is not transmitted to the probe information collection center 4. Therefore, probe information including useless position information is transmitted to the probe information collection center. Therefore, it is possible to avoid the occurrence of extra communication costs.
