<System configuration>
FIG. 1 is a block diagram illustrating a configuration example of a system used for taxi dispatch management. The communication system shown in FIG. 1 includes a customer portable terminal 10, a taxi dispatch center 20, a vehicle operation system 30, and a taxi vehicle 40.

  The customer portable terminal 10 is a terminal personally owned by each user who intends to use a taxi vehicle. Although various types of mobile terminals can be used as the customer mobile terminal 10, when the present invention is implemented, a predetermined dedicated application (application software) 12 is used as software necessary to realize the characteristic function. It is incorporated in the customer mobile terminal 10 in advance.

  Further, as shown in FIG. 1, the customer mobile terminal 10 has a wide area wireless communication unit 11 corresponding to a wireless communication standard such as LTE (Long Term Evolution) and a narrow area wireless communication corresponding to a wireless communication standard such as a wireless LAN. Part 14 is provided. Furthermore, the customer portable terminal 10 incorporates a screen display unit 13, a control unit (such as a microcomputer), an operation unit, and the like (not shown) as in a general portable terminal.

  The taxi dispatch center 20 receives a request for dispatch from a customer who wants to use a taxi and performs processing for reserving a taxi vehicle. The taxi dispatch center 20 includes a dispatch arrangement system 100 and a vehicle / traffic information management system 200.

  The dispatch arrangement system 100 includes a server that provides a predetermined website that exists on the Internet, for example, and can accept taxi reservations according to access from the customer mobile terminal 10 to the website. The vehicle / traffic information management system 200 manages the taxi vehicle status and various traffic information of each taxi company. Also, the vehicle / traffic information management system 200 can give a taxi dispatch instruction to the taxi company's vehicle operation system 30 in accordance with the taxi reservation accepted by the dispatch arrangement system 100.

  The vehicle operation system 30 of each taxi company individually manages the operation state of all taxi vehicles managed by this company. The vehicle operation system 30 is connected to the vehicle / traffic information management system 200 of the taxi dispatch center 20 via a predetermined communication line. Further, the vehicle operation system 30 includes a vehicle allocation wireless communication unit 31 such as an AVM (Automatic Vehicle Monitoring) system.

  That is, the vehicle operation system 30 grasps the operation status of each taxi vehicle such as the current position, empty / actual vehicle, and vehicle speed in real time by wireless communication with the vehicle-mounted device mounted on each taxi vehicle. Moreover, the vehicle operation system 30 can provide information or give an instruction to each taxi vehicle as necessary.

  Each taxi vehicle managed by the taxi company has a dispatching radio communication unit 41 such as an AVM system, and a navigation on-vehicle device 42. Further, the taxi vehicle of the present embodiment is also equipped with a narrow area wireless communication unit 43. The narrow-area wireless communication unit 43 corresponds to a wireless communication standard such as a wireless LAN and functions as an access point.

  Therefore, each taxi vehicle can always communicate with the vehicle operation system 30 of the taxi company that manages the taxi vehicle via the dispatch wireless communication unit 41. The on-vehicle navigation device 42 displays, for example, a screen for deciding a vehicle destination when picking up a customer, and presents a route to the vehicle destination, a route to the destination, map information, etc. to the taxi crew To display a screen for

<Overview of system operation>
When the communication system shown in FIG. 1 is used, a highly convenient taxi dispatch service can be realized as described below by performing the communications C01 to C14 shown in FIG.

  When a customer who wants to use a taxi reserves a taxi dispatch, the customer operates a dedicated application 12 incorporated in the customer mobile terminal 10 to access the reservation website of the taxi dispatch center 20, for example. That is, by communication C02 between the wide area wireless communication unit 11 and the vehicle allocation system 100, information necessary for taxi reservation, for example, personal information of the customer to be reserved, desired vehicle destination point, destination, time, etc. 10 transmits.

  The vehicle / traffic information management system 200 of the taxi dispatch center 20 generates dispatch information including taxi reservation contents from the customer received by the dispatch arrangement system 100, and this dispatch information is transmitted to the corresponding taxi company through a communication C03. 30. In addition, the vehicle operation system 30 transmits the dispatch information received from the vehicle / traffic information management system 200 to all taxi vehicles all at once by the communication C04.

  The vehicle-mounted device of each taxi vehicle sends the vehicle allocation information acquired by the vehicle allocation wireless communication unit 41 by communication C04 to the vehicle-mounted device 42 for navigation by communication C05. Therefore, information such as the vehicle allocation destination reserved by each taxi customer is displayed on the display screen of the on-vehicle navigation device 42. In an empty taxi vehicle, the crew member can confirm the reservation contents of the customer displayed on the screen of the on-vehicle navigation device 42, and can respond to the request for dispatch by the crew member's input operation. For example, the crew member performs an operation for accepting a reservation for a reservation in which a place close to the current position of the host vehicle is designated as a destination.

  When the crew member accepts the request for dispatch, the response to the dispatch information received by the in-vehicle navigation device 42 is transmitted from the taxi vehicle 40 to the vehicle operating system 30 of the taxi company by communication C06, C07. Further, this response is transmitted to the vehicle / traffic information management system 200 of the taxi dispatch center 20 by communication C08.

  When the vehicle / traffic information management system 200 detects the response received by the communication C08, the vehicle allocation system 100 of the taxi allocation center 20 generates taxi allocation information together with the reservation reception for the taxi reservation input as the communication C02 from the customer. These are transmitted to the customer portable terminal 10 by communication C09.

  Among the taxi dispatch information transmitted by the dispatch system 100, in addition to general information such as taxi car number (number plate number or radio number), car body color, car body appearance photograph, etc. Information on a unique identifier used when specifying a vehicle by distance is included.

  As a specific example, the taxi dispatch information includes a unique character string SSID (Service Set Identifier) for identifying the narrow area wireless communication unit 43 which is an access point of the wireless LAN. Of course, it is also possible to perform narrow-area wireless communication using a communication method other than wireless LAN. In this case, an identifier other than SSID is used.

  The dedicated application 12 in the customer mobile terminal 10 acquires the taxi dispatch information identifier (SSID) received by the wide area wireless communication unit 11 as a result of the taxi reservation by the communication C01, and uses this identifier (SSID). The narrow area wireless communication unit 14 is controlled by the communication C11.

  In this case, the narrow-area wireless communication unit 14 attempts to detect a wireless LAN access point having a target identifier (SSID) through wireless LAN communication C12. For example, when a taxi vehicle reserved by a customer has come to a position close to the customer, the taxi vehicle 40 exists within a range (for example, a radius of about 100 m or less) that can be communicated by wireless LAN. The narrow area wireless communication unit 14 of the customer mobile terminal 10 can detect the presence of the taxi vehicle 40.

  Further, for example, by using a plurality of antennas 15, it is possible to detect a relative direction with respect to the customer portable terminal 10 at a position where the taxi vehicle 40 exists, and it is also possible to detect a distance.

  The narrow area wireless communication unit 14 transmits the information of the taxi vehicle 40 detected by the communication C12 to the dedicated application 12 by the communication C13. The dedicated application 12 performs screen control of the screen display unit 13 by communication C14 based on the information on the taxi vehicle 40 acquired from the narrow area wireless communication unit 14. That is, the direction and distance regarding the current position of the taxi vehicle 40 reserved by the customer are displayed on the screen display unit 13 of the customer portable terminal 10.

  Therefore, even when there are a large number of taxi vehicles that are picked up by different customers near the customer, for example, in a nighttime downtown area, the customer can use the customer mobile terminal 10. From the contents of the screen display, it is possible to easily grasp the direction and distance of the target taxi vehicle reserved by the user, and to easily find the target taxi vehicle.

<Example of navigation screen display during taxi dispatch>
FIG. 2 is a front view showing a specific example of the display screen displayed by the navigation vehicle-mounted device 42 of the taxi vehicle 40. That is, in the communication system shown in FIG. 1, the on-vehicle navigation device 42 of each taxi vehicle 40 is based on the dispatch information (contents of the communication C04) transmitted from the vehicle / traffic information management system 200 and the vehicle operation system 30. For example, a display screen 44 as shown in FIG. 2 can be displayed.

  The display screen 44 shown in FIG. 2 assumes a case where dispatch information related to six or more taxi reservations is input. In the example shown in FIG. 2, the display order of each dispatch information is automatically adjusted so that the distance from the current position of the host vehicle to each placement destination is arranged in the order of closeness under the control of the on-vehicle navigation device 42. Has been.

  The display screen 44 shown in FIG. 2 includes a dispatch number display area 44a, a dispatch destination display area 44b, a destination display area 44c, a response button display area 44d, and a map display area 44e.

  The dispatch number display area 44a is used to display a list of numbers assigned to each dispatch information. The number “01” displayed in this area has the highest priority and represents the closest distance to the dispatch destination. Also, the number “02” represents the dispatch information with the second highest priority.

The dispatch destination display area 44b is used to display a list of addresses and customer names of dispatch destinations designated by customers for each dispatch information.
The destination display area 44c is used to display a list of destination addresses designated by the customer for each dispatch information.

  The response button display area 44d is used for a “response” input operation when the crew member accepts a dispatch service for the corresponding dispatch information. For example, when the crew member operates the response button 45 arranged at the top, it is possible to receive the vehicle allocation information to which the number “01” is assigned, that is, the vehicle allocation information of the vehicle allocation information closest to the vehicle allocation destination. .

  The map display area 44e is used for two-dimensionally displaying a map near the host vehicle. In addition, as shown in FIG. 2, a dispatch destination point icon 46 representing the dispatch destination point of each dispatch information and a host vehicle icon 47 representing the current position of the host vehicle are also displayed in the map display area 44e. be able to. The dispatch destination point icon 46 also represents a number assigned to the dispatch information.

  Therefore, in a taxi vehicle in an empty state, the crew member selects appropriate dispatch information from one or a plurality of dispatch information displayed on the display screen 44 as shown in FIG. Accept the appropriate dispatch service. Normally, when the crew member selects the dispatch information that is closest to the dispatch destination, the time required to pick up the train to the dispatch destination can be minimized, and taxi dispatch can be efficiently performed.

  However, if a place where the crew is not familiar with the location's geography is designated as the destination, even if the distance is close, it may be difficult to accurately deliver to the designated destination location. It may be difficult to operate a taxi efficiently in a short time. Therefore, when there are a plurality of vehicle allocation information, it is left to the crew member to decide which vehicle allocation information is selected.

<Vehicle allocation information processing in taxi vehicles>
FIG. 3 is a flowchart showing an example of dispatch information processing executed by the navigation vehicle-mounted device 42 of the taxi vehicle 40. That is, in the communication system as shown in FIG. 1, the on-vehicle navigation device 42 executes the processing shown in FIG. 3, thereby accepting the customer's dispatch reservation, receiving the vehicle to the destination, and reaching the destination. It becomes possible to operate efficiently. The process shown in FIG. 3 will be described below.

The navigation on-vehicle device 42 acquires all the vehicle allocation information transmitted from the vehicle operation system 30 by radio signals via the vehicle allocation wireless communication unit 41 (S11).
When a plurality of vehicle allocation information is acquired, the on-vehicle navigation device 42 calculates the distance by comparing the location of the vehicle allocation destination included in the vehicle allocation information with the current position of the host vehicle, and arranges them in order of increasing distance. In this state, a plurality of vehicle allocation information is displayed as a list, for example, as shown in FIG. 2 (S12).

  The in-vehicle device for navigation 42 identifies whether or not the own vehicle (own taxi) is in an empty state in S13, and if it is in an empty state, proceeds to the next S14. Information indicating whether or not the vehicle is in an empty state can be acquired from a taximeter (not shown) mounted on the host vehicle.

The on-vehicle navigation device 42 monitors the state of the response button 45 shown in FIG. 2 in S14, and when detecting that the response button 45 has been pressed, proceeds to the next S15.
The on-vehicle navigation device 42 generates response information for responding to one vehicle allocation information corresponding to the response button 45 pressed in S14 in S15. This response information is transmitted to the taxi dispatch center 20 via the dispatching radio communication unit 41 and the vehicle operation system 30.

  Since the on-vehicle navigation device 42 has a function equivalent to that of a general car navigation system, it is possible to generate route information representing an appropriate movement route for moving from the current position to a specific point. Therefore, the on-vehicle navigation device 42 generates route information to the destination location of the dispatch information corresponding to the response button 45 selected in S14, and sets the navigation function so that the taxi vehicle is operated according to this route. (S16).

  By this navigation function, the information on the current position of the host vehicle is automatically updated, and a road map including the latest host vehicle position and guidance information indicating an appropriate moving direction such as a right turn or a left turn are displayed. Accordingly, the crew member of the host vehicle operates while being guided by the guidance display of the navigation function, and moves along the generated route to the destination of the dispatch destination. When the host vehicle arrives at the destination location, the process proceeds from S17 to S18.

  The on-vehicle navigation device 42 generates route information representing an appropriate movement route for moving from the vehicle allocation destination of the vehicle allocation information, that is, the current position, to the destination included in the vehicle allocation information in S18, and along this route Reset the navigation function so that taxi vehicles can be operated.

  The reserved customer finds and rides the own vehicle at the destination, and the crew member operates the taxi vehicle to the destination while being guided by the navigation function with the customer on the own vehicle (S19). When arriving at the destination, the processing shown in FIG. 3 ends.

<Vehicle dispatch taxi exploration processing of customer mobile terminal>
An example of a dispatch taxi exploration process in the customer mobile terminal 10 is shown in FIG. Further, FIG. 5 shows a specific example of the processing related to position detection in S24 shown in FIG.
That is, the dedicated application 12 executed on the customer portable terminal 10 shown in FIG. 1 executes the dispatch taxi exploration process shown in FIG. 4 after the taxi reservation by the communication C02.

  The dedicated application 12 acquires the identifier (SSID) of the specific access point (wireless LAN on the reserved taxi vehicle) included in the dispatch information transmitted from the taxi dispatch center 20 to the customer portable terminal 10 by the communication C09. In S21, it is confirmed whether or not it has been completed.

  The dedicated application 12 assigns the identifier (SSID) acquired in S21 as a search target of a wireless LAN communication destination access point in the narrow area wireless communication unit 14 (S22), and starts searching for this access point. However, in this case, since the communication is wireless LAN communication, the search range is limited to a relatively narrow range.

  When the narrow area wireless communication unit 14 detects an access point that matches the identifier (SSID) assigned in S22, the process of the dedicated application 12 proceeds from S23 to S24, and a position detection process for specifying the position of the target taxi vehicle To start. That is, the position detection process shown in FIG. 5 is started.

  The dedicated application 12 acquires the position information of the reserved taxi vehicle 40 via the narrow area wireless communication unit 14 (S31). This position information is specified at predetermined time intervals by the GPS function of the taxi vehicle 40, for example, and is transmitted to the customer portable terminal 10 using narrow area wireless communication. Next, the dedicated application 12 specifies the direction in which the customer mobile terminal 10 is facing using the azimuth magnetic needle function of the customer mobile terminal 10 (S32).

  Further, the dedicated application 12 specifies the current position of the customer mobile terminal 10 using a GPS function (not shown) of the customer mobile terminal 10 (S33). Then, the dedicated application 12 specifies the relative position of the taxi vehicle 40 with respect to the customer mobile terminal 10 based on the location information of the customer mobile terminal 10 and the reserved taxi vehicle 40, and the position information and the customer Based on the direction in which the mobile terminal 10 faces, the relative direction of the taxi vehicle 40 with respect to the customer mobile terminal 10 is calculated.

  The above position detection process is an example. For example, if the customer portable terminal 10 can form directivity in the antenna 15 for narrow area wireless communication, the position where the GPS function is not used as follows. Detection processing is possible.

  The dedicated application 12 controls the narrow area wireless communication unit 14 to form directivity in the antenna 15 for narrow area wireless communication. For example, when a plurality of antennas 15 can be used, the reception characteristics of the antennas 15 can be given directivity by synthesizing the reception signals of the plurality of antennas 15 with the phases shifted from each other. In addition, the directivity can be changed by adjusting the phase difference of the received signal and the synthesis condition.

  The dedicated application 12 controls the narrow area wireless communication unit 14 to change the directivity peak direction (direction in which the sensitivity is maximum) in the antenna 15 for narrow area wireless communication so as to rotate the target identifier ( The reception intensity distribution of radio waves including SSID) is measured. Next, the dedicated application 12 detects the direction with the maximum reception intensity from the radio wave reception intensity distribution obtained by the measurement, and identifies the direction of the reserved taxi vehicle. Then, the dedicated application 12 calculates the distance from the current position of the customer mobile terminal 10 to the reserved taxi vehicle based on the reception intensity in the peak direction in the reception intensity distribution.

  The dedicated application 12 repeatedly executes the position detection process shown in FIG. 5 or the position detection process described above, and sequentially reflects the result of this process in the position data of the reserved taxi (S25 in FIG. 4).

  In the present embodiment, the dedicated application 12 has two display modes, “arrow mode” and “radar mode”. When the user of the customer mobile terminal 10 selects “arrow mode” as the display mode, the processing of the dedicated application 12 proceeds from S26 to S27. When the user selects “radar mode” as the display mode, the process proceeds from S26 to S28. .

  The dedicated application 12 uses the latest position data detected in S25 to display an arrow pattern indicating a relative direction when viewing the current position of the reserved taxi from the current position of the customer mobile terminal 10 on the screen display unit 13. It is displayed (S27).

  The dedicated application 12 displays the current position of the reserved taxi and the positional relationship with the customer portable terminal 10 on the screen display unit 13 in a display form such as a radar screen using the latest position data detected in S25 ( S28).

  The dedicated application 12 detects in S29 that the user of the customer mobile terminal 10 has boarded a reserved taxi, or ends the operation of FIG. 4 when the dedicated application 12 itself ends. Until then, the display of S27 or S28 and the update of position data (S25) are repeated.

  Further, the customer mobile terminal 10 uses the reserved taxi identifier (SSID) transmitted from the taxi dispatch center 20 at the time of reservation to identify the target access point by narrow area wireless communication such as wireless LAN, Can detect the current location of the taxi vehicle booked. Therefore, even in a situation where there are a large number of taxi vehicles, such as in a downtown area at night, a reserved taxi customer can easily find and board a taxi that he / she should ride.

  Further, by displaying the “radar mode” screen shown in FIG. 6A or the “arrow mode” screen shown in FIG. 6B, the user of the customer portable terminal 10 can confirm the reserved taxi vehicle. Since it can be easily grasped in real time in which direction it is with respect to its current position, it is possible to shorten the time required to get on the reserved taxi vehicle.

  Further, when searching for a taxi vehicle reserved by the customer mobile terminal 10, narrow-area wireless communication is used, so there is no need to use wide-area wireless communication that involves charging. Therefore, even if the dedicated application 12 of the customer mobile terminal 10 continues the taxi vehicle search operation continuously for a long time, it is not necessary for the customer to pay a special fee.

  Further, in each taxi vehicle 40 in an empty state, the on-vehicle navigation device 42 displays a screen as shown in FIG. 2 on the basis of the dispatch information transmitted from the vehicle operation system 30, so that the crew member can select an appropriate one according to his / her own judgment. It is possible to select the dispatch information and respond to the dispatch request. For example, the operation efficiency of a taxi can be increased in response to a vehicle allocation request of a vehicle allocation destination that is closest to the current position of the taxi vehicle. In addition, if the destination and destination of the crew are unfamiliar with the geography of the crew, it is possible to increase the taxi operation efficiency by selecting other dispatch information and responding. .
