Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle management system, a mobile station apparatus, and a base station apparatus that manage operations of various business vehicles while performing communication between each vehicle and a center.
[0002]
[Prior art]
Conventionally, in order to efficiently operate business vehicles such as taxis and luggage carriers, each vehicle is equipped with a communication device and communicates with the management center. A vehicle management system is used. Each vehicle is equipped with a function for specifying its own vehicle position by GPS (Global Positioning System) or the like. The communication device mounted on each vehicle serves as a mobile station, and periodically notifies vehicle data including the vehicle position to the base station on the management center side. The management center receives vehicle data and provides information and gives instructions to operate each vehicle efficiently. When communication between the vehicle and the center is used, traffic information can be collected and traffic such as roads can be managed (see, for example, Patent Document 1 and Patent Document 2).
[0003]
In order to facilitate road traffic, a “non-stop automatic toll payment system” called ETC (Electronic Toll Collection System) that automates toll payment on toll roads is also available. The ETC is used by inserting an ETC card (IC card for ETC) in which contract information or the like is recorded in an in-vehicle device mounted on the vehicle. A roadside antenna is installed at the toll gate on the toll road, and information such as tolls is registered in both the computer system on the toll road side and the ETC card while performing wireless communication with the vehicle-mounted device. This process actually requires only a short time, and the vehicle can pass without stopping at the toll booth.
[0004]
For example, in the case of an entrance using ETC, a vehicle inserts an ETC card into the vehicle-mounted device in advance, and passes through an ETC dedicated gate having a display board indicating that ETC can be used. When the vehicle passes through the ETC dedicated gate, wireless communication is performed between the roadside antenna and the vehicle-mounted device. When wireless communication is normally performed, a sign of passage is displayed on the display board, and the bar or the like blocking the passage in front is released. By wireless communication, the user receives an invisible ticket.
[0005]
In the case of an exit that uses ETC, fee settlement is automatically performed by wireless communication when passing through an ETC dedicated gate having a display board indicating that ETC can be used. When the fee settlement is performed normally, a toll and a passage sign are displayed on the display board, and a bar or the like blocking the passage in the front is raised to allow the passage. A toll road use history generation apparatus that uses such an ETC function has also been proposed (see, for example, Patent Document 3).

[Problems to be solved by the invention]
For example, in the case of a taxi vehicle, if it is in an empty state, it is in a state of waiting for the appearance of a customer in the vicinity of its own vehicle position, and it is desired that the customer get on board in response to a dispatch instruction. However, if you are traveling on a toll road including a toll road, an elevated road, a tunnel, etc. where access is restricted, it is not always possible to respond immediately even if you receive a dispatch instruction. The place leaving the restricted access road may be far from the indicated position.
[0008]
If the vehicle is equipped with a device such as GPS that identifies its own vehicle location and the vehicle location data is notified to the management center, whether the vehicle is traveling on restricted access roads including toll roads such as expressways May be determined with reference to road map data or the like. However, since the identification accuracy of the vehicle position is not so high, it is difficult to identify the road on which the vehicle is traveling from the vehicle position of the vehicle in an area where the road density is high.
[0009]
For this reason, in order to change the management status depending on whether or not the vehicle is traveling on a toll road, an operation switch is provided on the mobile station device mounted on the vehicle, and a vehicle passenger such as a driver is traveling on the toll road. It is necessary to perform a switch operation indicating that In this way, the management center can recognize that the vehicle is traveling on a toll road or the like, but no special control is performed for communication with the mobile station device. Even if the mobile station apparatus periodically notifies the position of the vehicle on the toll road, it cannot respond to a command from the management center until it leaves the toll road.
[0010]
For this reason, even if the management center recognizes that the vehicle is traveling on a toll road, the vehicle management system has the following problems.
(1) An operation of a driver or the like is required to notify the management center of traffic on a toll road or the like.
(2) When notification of traffic on a toll road or the like is given by a driver's report by a switch operation, an operation error or the like is also assumed. In the management center, various processes are required to determine an operation error.
(3) Since a vehicle traveling on a toll road or the like is handled in the same manner as usual, the mobile station device needs to communicate data that is unlikely to be an effective target for vehicle operation management.
[0011]
An object of the present invention is to provide a vehicle management system, a mobile station apparatus, and a base station that can perform management different from other cases when the vehicle is traveling on an access restricted road such as a toll road where access is restricted. Is to provide a device.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a schematic configuration of a vehicle management system 1 according to an embodiment of the present invention. The vehicle management system 1 according to the present embodiment includes a mobile station device 3 mounted on a business vehicle 2 such as a taxi and a base station device 5 installed in the management center 4 while communicating with the management center 4 side. The operation of the vehicle 2 is managed by For convenience of explanation, only one vehicle 2 is shown, but the management center 4 manages a plurality of vehicles 2 in the same manner. The mobile station device 3 mounted on the vehicle 2 includes an in-vehicle terminal 10 that controls the entire mobile station device 3, a communication device 11 that performs wireless communication with the base station device 5, and a GPS antenna that receives radio waves from a GPS artificial satellite. 12 and an ETC device 13 that automatically settles a toll on the toll road. The base station device 5 installed in the management center 4 includes a personal computer 20 that performs vehicle management processing, a communication device 21 that performs wireless communication with the mobile station device 3, and an interface between the personal computer 20 and the communication device 21. A communication I / F device 22 to be performed and a display 23 for displaying current positions and dynamics of the plurality of vehicles 2 are included.
[0035]
The wireless communication between the communication devices 11 and 21 is performed using, for example, a 150 MHz band or a 400 MHz band radio wave. A mobile phone may be used as the communication device 11 or 21.
[0036]
In this embodiment, at least one vehicle 2 is an ETC that detects entry / exit on toll roads as entry / exit restriction road detection means for detecting whether or not the vehicle is passing through an entry / exit restriction road with restrictions on entry / exit. The device 13 is mounted. In response to the operation of the ETC device 13, the mobile station device 3 notifies the base station device 5 that the vehicle 2 enters or exits the toll road when entering the toll road and leaving the toll road, respectively. To do. The communication between the mobile station device 3 and the base station device 5 of the vehicle 2 is suppressed until the vehicle enters the toll road and leaves.
[0037]
By the operation of the ETC device 13, it is possible to know with high reliability the time of entry from a toll gate on a toll road such as an expressway and the time of exit from the toll gate. That is, it is possible to reliably determine whether or not the vehicle 2 is traveling from the entrance toll gate to the exit toll gate. When the vehicle is passing the toll gate on the entrance side and traveling toward the toll gate on the exit side, it cannot leave the toll road at least until it passes the toll gate on the exit side. Even if the vehicle 2 is instructed to leave the toll road during this time, it cannot be said to be an effective instruction. Since it is certain that the vehicle 2 is traveling on a toll road, even if the data of the vehicle position of the vehicle 2 is communicated frequently, it is a position on the toll road that is traveling and can be easily predicted. is there. Further, no change occurs in the dynamics of the vehicle 2.
[0038]
Therefore, the mobile station device 3 and the base station device 5 of the management center 4 suppress communication until the vehicle 2 enters the toll road between the toll gates and exits. As a result, it is possible to reduce the burden required for sending and receiving data that is not effective in terms of management of the vehicle 2. If the vehicle 2 is a taxi or the like, it is possible to prevent the vehicle from being dispatched at a position where the vehicle 2 cannot get out of the toll road. If there is a vehicle allocation request from the customer, even if the vehicle 2 traveling on the toll road is close, the customer cannot be picked up, so it is better to give a vehicle allocation instruction to other vehicles not traveling on the toll road etc. It is possible to reduce the waiting time until the vehicle is picked up and to realize quick customer service.
[0039]
The vehicle 2 is equipped with an ETC device 13 that performs wireless communication with a roadside antenna installed at a toll booth when entering or leaving a toll road, and automatically pays the usage fee. When a beacon or the like that performs local broadcasting is installed on a road or the like, if a device that receives the broadcast is installed, it can be detected that the vehicle is traveling on the road. In addition, it is equipped with an imaging device such as a camera, images a guide sign provided along the road, etc., and detects whether or not the vehicle is traveling on a toll road by character recognition of the guidance display included in the image You can also. Use image recognition to detect whether you are driving on restricted access roads where access is restricted, not only on toll roads, but also on elevated roads, long bridges and tunnels, and automobile-only roads. It can be used as an access restricted road detection means.
[0040]
When the vehicle 2 is traveling on the restricted access road, the vehicle 2 cannot freely leave the restricted access road as in the above-described toll road, and communication with the management center 4 during travel is not very effective. Because.
[0041]
FIG. 2 schematically shows a state in which the mobile station device 3 and the base station device 5 communicate with each other in the vehicle management system 1 shown in FIG. While the vehicle 2 is traveling on a general road, communication is periodically performed, and for management, data indicating the position of the own vehicle obtained by GPS and the dynamics of an actual vehicle or an empty vehicle as a taxi vehicle are periodically updated. For example, transmission is performed from the mobile station apparatus 3 to the base station apparatus 5 at times t1, t5, t9, and the like. The base station apparatus 5 gives an instruction for dispatching at times t3, t7, t11, etc. as a response to receiving data from the mobile station apparatus 3 at times t2, t6, t10. The mobile station device 3 receives an instruction from the base station device 5 at times t4, t8, t12, and the like. A system such as polling for sequentially calling a plurality of mobile station apparatuses 3 from the base station apparatus 5 can also be used.
[0042]
When the vehicle enters the toll road from the general road at time t20, the ETC device 13 in FIG. 1 operates when entering the toll gate on the toll road. When detecting the operation of the ETC device 13, the in-vehicle terminal 10 notifies the base station device 5 from the communication device 11. When the base station apparatus 5 receives the notification at time t21, the base station apparatus 5 transmits a control signal for performing no periodic communication to the mobile station apparatus 3 at time t22. When the mobile station apparatus 3 receives a control signal that does not perform regular communication at time t23, the mobile station apparatus 3 stops transmitting regular data. While passing the toll road, the dispatch data and the like are not transmitted from the management center 4 to the vehicle 2.
[0043]
When the ETC device 13 is activated when exiting the toll road exit toll gate at time t30, the mobile station device 3 notifies the base station device 5 from the toll road in response to the operation of the ETC device 13. I do. The base station apparatus 5 receives the notification at time t31, and at time t32, transmits a control signal for resuming regular communication for canceling the control signal transmitted at time t22 and not performing regular communication. After time t33 when the mobile station device 3 receives the control signal for resuming regular communication, regular communication is performed in the same manner as from time t1 to before time t20.
[0044]
In this way, when entering or leaving the toll road, the vehicle 2 side responds to the operation of the ETC device 13 that performs wireless communication with the roadside antenna installed at the toll gate and automatically settles the usage fee. The mobile station device 3 notifies the base station device 5 of entering or leaving the toll road, so that it can be surely notified of entering and exiting the toll road regardless of the operation of the driver or the like. it can. Since the information based on the operation of the ETC device 13 is highly reliable, it is certain that the vehicle 2 is traveling on the toll road, and data communication that is not very effective from the vehicle 2 side, and useless from the management center 4 side. Communication such as dispatch data can be avoided. As a result, communication traffic can be reduced, and communication charges can be reduced when communication is charged and charged according to the amount of data.
[0045]
In the present embodiment, communication between the mobile station device 3 and the base station device 5 is suppressed so as not to be performed while traveling on a toll road. Since the mobile station device 3 and the base station device 5 do not communicate until the vehicle 2 enters the toll road until it leaves, the management center 4 uses the time during which communication is not performed. Information on other vehicles that are not traveling on the access restricted road can be collected more effectively. On the vehicle 2 side traveling on the toll road, the burden of response to communication can be avoided.
[0046]
Further, the suppression of communication between the mobile station apparatus 3 and the base station apparatus 5 can be performed by increasing the time interval for performing communication. Since the communication between the mobile station device 3 and the base station device 5 is suppressed by increasing the communication time interval until the vehicle enters the toll road or the like and exits, the communication is not performed. By using this time, the management center 4 can collect information on other vehicles that are not traveling on toll roads more effectively. On the side of the vehicle 2 traveling on a toll road or the like, the frequency of communication is reduced, and the burden of response can be reduced.
[0047]
In addition, the suppression of communication between the mobile station device 3 and the base station device 5 can be performed by increasing the distance interval for communication. Communication between the mobile station device 3 and the base station device 5 is suppressed by increasing the distance interval for communication until the vehicle 2 enters and exits the toll road or the like. The same effect as when the time interval is increased and the time interval is increased can be obtained.
[0048]
In the present embodiment, communication between the mobile station device 3 and the base station device 5 is suppressed by an instruction by the base station device 5 transmitting a control signal to the mobile station device 3. Since the communication performed by the vehicle 2 while traveling on the toll road is suppressed by the command from the base station device 5, it is possible to suppress communication that is not effective in terms of vehicle management without requiring the operation of the passenger or the like of the vehicle 2. it can. The mobile station device 3 may notify the base station device 5 that the communication is to be suppressed while traveling on a toll road or the like, so that the communication is automatically suppressed.
[0049]
The mobile station device 3 can be provided with a function that operates according to data set from the base station device 5. As a result, communication between the mobile station device 3 and the base station device 5 can be suppressed by setting data from the base station device 5 to the mobile station device 3. Since the base station device 5 sets the data of the time interval or the distance interval to the mobile station device 3 to suppress communication, for example, if the data is set according to the degree to which the suppression is necessary, the vehicle 2 is traveling Appropriate communication suppression can be performed according to the type of toll road.
[0050]
FIG. 3 shows an example in which taxi dispatch is performed using the vehicle management system 1 of FIG. Assuming that the vehicle 2b traveling on the toll road 32 is closer to the vehicle 2a traveling on the general road 31 as a vehicle closer to the customer 30 requesting an incoming vehicle. When the customer 30 makes a telephone call to the wireless dispatch center 40 corresponding to the management center 4 in FIG. 1, the calling telephone number notification service provided by NTT is used, the customer database 41 is referred to, and the customer 30's home, etc. Information about where to use is automatically searched. The base station apparatus 5 of the present embodiment uses the general road 31 even when the vehicle 2b traveling on the toll road 32 is closer to the usage location of the customer 30 than the vehicle 2a traveling on the general road 31. A command to receive a vehicle is issued to the traveling vehicle 2a.
[0051]
In the embodiment described above, it is automatically detected that the vehicle 2 is traveling on an access restricted road such as a toll road, but the mobile station device 3 is provided with an operation switch or the like, and the vehicle 2 It is also possible to notify that the vehicle is traveling on a toll road or the like by the operation of a passenger such as a driver. If it is a passenger's operation, it can be easily notified regardless of the type of restricted access road. However, there is a possibility of operating mistakes, etc. When entering or exiting a toll road, the ETC device 13 that automatically settles the usage fee by wirelessly communicating with the roadside antenna installed at the toll gate However, it is possible to reliably detect entering and exiting toll roads and to perform highly reliable management.
[0052]
Moreover, the present invention can be similarly applied to not only a taxi but also a vehicle for parcel delivery, a baggage transportation to a store, and the like that are managed as the vehicle 2.
[0053]
【The invention's effect】
As described above, according to the present invention, the vehicle management system operates the vehicle on the center side while the mobile station device installed in each of the vehicles communicates with the base station device installed in the center. When managing the vehicle, communication is suppressed until the vehicle enters the restricted access road where the entrance is restricted. Since the entry / exit on the entry / exit restricted road is performed by the entry / exit restricted road detecting means, the entry / exit restricted road can be reliably detected without being operated by the vehicle passenger. If the vehicle is a taxi or the like, it is possible to perform vehicle management that is different from when traveling on other general roads and the like by not dispatching the vehicle at a position where it is not possible to exit from the road on which it is traveling.
[0054]
Further, according to the present invention, it is possible to automatically perform the notification of the vehicle entering or leaving the toll road with high reliability by using the operation of the ETC device. It is certain that the vehicle is traveling on a toll road, and communication such as ineffective data communication from the vehicle side and useless dispatch data from the center side can be avoided. As a result, communication traffic can be reduced, and communication charges can be reduced when communication is charged and charged according to the amount of data.
[0055]
Further, according to the present invention, the time interval for communication between the mobile station device and the base station device is increased while the vehicle is traveling on the restricted access road, so the time during which communication is not performed is used. The center can collect information on other vehicles that are not traveling on the restricted access road more effectively. On the vehicle side, the frequency of communication decreases, and the burden of response can be reduced.
[0056]
Further, according to the present invention, the distance between the mobile station device and the base station device for communication is increased while the vehicle is traveling on the restricted access road. Information about other vehicles that are not traveling on the restricted road can be collected more effectively. On the vehicle side, the frequency of communication decreases, and the burden of response can be reduced.
[0057]
According to the present invention, since the vehicle does not communicate between the mobile station device and the base station device while traveling on the restricted access road, the center stores information on other vehicles not traveling on the restricted access road. It can be collected more effectively. On the vehicle side, the burden of response to communication can be avoided.
[0058]
Moreover, according to this invention, the communication which is not effective on vehicle management can be suppressed with the instruction | command from a base station apparatus, while a vehicle drive | works the access control road.
[0059]
Further, according to the present invention, since the base station apparatus sets data to the mobile station apparatus and suppresses communication, it is possible to set data according to the degree to which suppression is necessary and perform appropriate communication suppression. it can.
[0060]
Furthermore, according to the present invention, from the mobile station device of a vehicle equipped with an ETC device that automatically settles a usage fee when entering or leaving a toll road, the base station device installed in the center is operated based on the operation of the ETC device. , When you enter the toll road and when you leave the toll road, you can automatically notify the entrance and exit of the toll road with high reliability, and the vehicle management can be done while the toll road is passing It is possible to effectively function a vehicle management system that performs differently when the vehicle is on the road.
[0061]
In addition, according to the present invention, communication performed between the ETC device and the base station device from the time when the ETC device detects entry to the toll road until it detects exit from the toll road according to data set by communication from the base station device. Therefore, useless communication while traveling on a toll road can be reliably suppressed based on a command from the base station device.
