Description

Technical Field

[0001] The present invention relates to an information processing system, an information processing program, and an information processing method.

Background Art

[0002] Normally, in a taxi, a taximeter installed in the vehicle measures the driving distance and calculates the fare. A conventional taximeter measures the actual measured value of the distance using a rotation gauge attached to the tire, and since it is subject to metrology, regular inspections are obligatory.

[0003] On the other hand, currently, the introduction of a taxi soft meter is being considered by the Ministry of Land, Infrastructure, Transport and Tourism. Different from a conventional taximeter, a taxi soft meter measures the distance using GPS and calculates the fare, and it is also possible to use a general-purpose Android / iOS terminal as a taximeter.

[0004] Patent Document 1 discloses a technique for calculating the fare in real time during driving using the position information of a vehicle specified by GPS.

Problems to be Solved by the Invention

[0006] However, in a soft meter that uses GPS, there is a problem that the meter display during driving becomes inaccurate due to the deterioration of the vehicle positioning accuracy in places where GPS is weak, such as inside a tunnel, a multipath area, or under an elevated structure.

[0011] Embodiments of the present invention will be described in detail below with reference to the attached drawings. In each drawing, components having equivalent functions are denoted by the same reference numerals, and detailed descriptions of components with the same reference numerals will not be repeated.

[0012] In the embodiments described below, a taxi may be used as an example to describe the "vehicle" to which the soft meter terminal 3 is installed. However, the "vehicle" is not limited to a taxi, as long as it is a vehicle to which fares are calculated according to the distance traveled to transport passengers. For example, it could be a welfare transport vehicle (care taxi) or an escort vehicle for a designated driver service. The "vehicle" could also be an autonomous vehicle. Furthermore, the "vehicle" could be a vehicle used for ride-sharing, specifically, a shared taxi used by an unspecified number of passengers.

[0013] (Configuration of the information processing system) Figure 1 is a diagram illustrating the schematic configuration of an information processing system 1 according to one embodiment. In this figure, each functional unit that performs a function can be considered a means for performing that function.

[0014] As shown in FIG. 1, the information processing system 1 includes a soft meter terminal 3 and a passenger terminal 2. The soft meter terminal 3 and the passenger terminal 2 are communicably connected to each other via a network 4 such as USB or Bluetooth. The network 4 may be either a wired line or a wireless line, and the type and form of the line are not limited. Note that at least a part of the soft meter terminal 3 and the passenger terminal 2 is realized by a computer.

[0015] First, the passenger terminal 2 will be described. The passenger terminal 2 is used or viewed by the passengers of the vehicle. For example, it may be a monitor for the rear seats attached to the back side or the ceiling of the headrests of the driver's seat and the passenger seat, or it may be a mobile terminal such as a smartphone or a tablet terminal held by the passengers. It may also be a terminal installed at a position where the display can be confirmed from the position of the rear seats near the driver's seat.

[0016] As shown in FIG. 1, the passenger terminal 2 has a communication unit 21 and a display unit 25. The communication unit 21 and the display unit 25 are communicably connected to each other.

[0017] The communication unit 21 is a communication interface between the passenger terminal 2 and the network 4. The communication unit 21 transmits and receives information between the passenger terminal 2 and the soft meter terminal 3 via the network 4.

[0018] The display unit 25 is an interface for displaying various information to the passengers from the passenger terminal 2, and is, for example, a video display means such as a liquid crystal display or an organic EL display.

[0019] Next, the soft meter terminal 3 will be described. The soft meter terminal 3 uses GPS to measure distance and calculate fares, and may be fixed in a location specified by laws and regulations, such as next to the driver's seat. A general-purpose Android / iOS device such as a smartphone or tablet may be used as the soft meter terminal 3. As shown in Figure 1, the soft meter terminal 3 has a communication unit 31, a control unit 32, a storage unit 33, a positioning unit 34, and a display unit 35. Each unit 31 to 35 is connected to each other so as to be able to communicate.

[0020] Of these, the communication unit 31 is the communication interface between the soft meter terminal 3 and the network 4. The communication unit 31 transmits and receives information between the soft meter terminal 3 and the passenger terminal 2 via the network 4.

[0021] The display unit 35 is an interface that displays various information to the driver and passengers from the soft meter terminal 3, and is, for example, an image display means such as a liquid crystal display or an organic EL display. The information displayed on the display unit 35 of the soft meter terminal 3 and the information displayed on the display unit 25 of the passenger terminal 2 may be configured to mirror each other.

[0022] The positioning unit 34 is a positioning means used by the location information acquisition unit 32a, described later, to obtain information about the current location of the soft meter terminal 3. The positioning unit 34 includes, for example, a radio wave receiving module such as GPS or the Quasi-Zenith Satellite System (QZSS). The positioning unit 34 may further include an acceleration sensor, a geomagnetic sensor, and the like.

[0023] The storage unit 33 is a non-volatile data storage device such as flash memory or a hard disk. Various types of data handled by the control unit 32 are stored in the storage unit 33. For example, the storage unit 33 includes a route network information database 33a containing traffic network information, a map information database 33b containing map information, and a positioning information database 33c.

[0024] Transportation network information defines transportation networks such as railways and buses, as well as road networks. Transportation network information includes route information, timetable information, and fare information for various modes of transport. Road network information is represented by a combination of node data, which represents points of connection in the road network such as intersections, and link data, which represents road sections between nodes.

[0025] Map information includes map data such as road maps for the entire country and each region, and map object information associated with the map data. Map object information includes shape information about the shapes of facilities displayed on the map, annotation information about notes displayed on the map, and symbol information about symbols displayed on the map. Map information may also include route map information related to public transportation routes.

[0026] The above transportation network information and map information may be updated at predetermined intervals.

[0027] The positioning information database 33c stores the vehicle's location information, acquired by the location information acquisition unit 32a (described later), along with time information and positioning reliability information.

[0028] Furthermore, the storage unit 33 does not necessarily have to be located within the soft meter terminal 3; part or all of the storage unit 33 may be located in another device that is connected to the soft meter terminal 3 via the network 4 in a manner that allows communication with it.

[0029] As shown in Figure 1, the control unit 32 includes a location information acquisition unit 32a, a fare calculation unit 32b, a fare display unit 32c, a positioning status determination unit 32d, a positioning failure information display unit 32e, a warning display unit 32f, and a traveled route display unit 32g. Each of these units 32a to 32g may be realized by the processor in the soft meter terminal 3 executing a predetermined program, or it may be implemented in hardware.

[0030] The location information acquisition unit 32a acquires information about the current location of the soft meter terminal 3 using the positioning information from the positioning unit 34. The location information acquisition unit 32a acquires the current location based on positioning information from radio navigation means such as GPS or the Quasi-Zenith Satellite System (QZSS). The location information acquisition unit 32a may also use positioning information from autonomous navigation means such as acceleration sensors or geomagnetic sensors for further positioning. Since the soft meter terminal 3 moves with the vehicle, the location information acquired by the location information acquisition unit 32a indicates the current location of the vehicle. The vehicle's location information acquired by the location information acquisition unit 32a is stored in the positioning information database 33c along with time information and positioning reliability information.

[0031] The fare calculation unit 32b refers to the map information database 33b and the positioning information database 33c, and calculates the fare by measuring the vehicle's mileage based on the vehicle's location information and map information acquired by the location information acquisition unit 32a.

[0032] The fare display unit 32c displays the fare calculated by the fare calculation unit 32b via the display unit 35, and also transmits a control signal to the passenger terminal 2 to display the fare, which is then displayed to the passenger via the display unit 25 of the passenger terminal 2 (see Figure 4).

[0033] The positioning status determination unit 32d determines whether the positioning status is good or bad based on the vehicle's location information acquired by the location information acquisition unit 32a. For example, if the acquisition of positioning information by radio navigation means such as GPS or QZSS fails, or if the acquisition of positioning information is successful but the reliability information of the positioning does not meet a predetermined standard, the positioning status determination unit 32d may determine that the positioning is poor, and if the reliability information of the positioning meets the standard, it may determine that the positioning is good. Alternatively, for example, the positioning status determination unit 32d may perform map matching to match the vehicle's location information to nearby roads obtained from map information, and if map matching fails, it may determine that the positioning is poor, and if map matching is successful, it may determine that the positioning is good. As for the "map matching" algorithm, for example, those described in Japanese Patent No. 3860474 and Japanese Patent No. 4175646 can be used. For mobile devices such as smartphones and tablets, it is possible to easily implement the "map matching" function by using, for example, the navigation development kit "NaviSDK" manufactured by Navitime Japan Co., Ltd.

[0034] When the positioning status determination unit 32d determines that positioning is inaccurate, the positioning failure information display unit 32e transmits a control signal to the passenger terminal 2 to display information regarding the uncertainty (variability) of the displayed fare, and displays it to the passenger via the display unit 25 of the passenger terminal 2. The manner in which the information regarding the uncertainty (variability) of the displayed fare is displayed is not particularly limited as long as it can attract the passenger's attention. For example, the fare display may be grayed out (see Figure 5), the degree of reliability of the information may be indicated by differences in shapes, numbers, or background colors, or a string of characters indicating that the fare is uncertain (variable) may be displayed (see Figure 6). When the positioning status determination unit 32d determines that positioning is inaccurate, the positioning failure information display unit 32e may also display the information regarding the uncertainty (variability) of the displayed fare on the display unit 35 of the soft meter terminal 3.

[0035] If the positioning status determination unit 32d determines that positioning is poor, the fare display unit 32c may stop updating the fare display on the passenger terminal 2 until the positioning status determination returns to good (i.e., the fare display may not be updated).

[0036] As one variation, if the positioning status determination unit 32d determines that positioning is poor, the fare display unit 32c may calculate the distance traveled based on map information and / or road images taken by the vehicle's camera (e.g., a drive recorder) to calculate an estimated fare, and display the calculated estimated fare as a guideline fare on the passenger terminal 2. Specifically, for example, if positioning is poor because the vehicle has entered a tunnel, the fare display unit 32c may identify the length of the tunnel based on map information, use the length of the tunnel as the distance traveled, predict how much the fare will increase by the time the vehicle exits the tunnel, and display this as a guideline fare on the passenger terminal 2.

[0037] Even if the positioning status determination unit 32d determines that positioning is inaccurate, the fare display unit 32c may display information indicating that the fare is being added on the display units 35 of the passenger terminal 2 and the soft meter terminal 3.

[0038] The warning display unit 32f may refer to the map information database 33b and the positioning information database 33c and, based on the vehicle's location information, map information, and / or road images taken by the vehicle's camera, detect in advance that the vehicle is about to enter a predetermined positioning failure area (e.g., inside a tunnel, a multipath zone, under an overpass, etc.) and display information regarding the uncertainty of the displayed fare on the passenger terminal 2 (see Figure 7). Specifically, for example, if map matching is performed to match the vehicle's location information to a nearby road obtained from map information, and the route obtained by map matching leads to a tunnel, the warning display unit 32f may determine that the vehicle will soon enter the tunnel and display information regarding the uncertainty of the displayed fare on the passenger terminal 2. Alternatively, for example, if a tunnel or a road sign is visible in the road images taken by the vehicle's camera, the warning display unit 32f may determine that the vehicle will soon enter the tunnel and display information regarding the uncertainty of the displayed fare on the passenger terminal 2.

[0039] The fare display unit 32c may display information on the display units 35 of the passenger terminal 2 and the soft meter terminal 3 indicating that fare accrual will continue even if the advance warning display unit 32f has detected in advance that a vehicle is entering a positioning failure area.

[0040] The traveled route display unit 32g refers to the map information database 33b and the positioning information database 33c, identifies the vehicle's traveled route based on the vehicle's location information and map information, and transmits a control signal to the passenger terminal 2 to display the traveled route, which is then displayed to the passenger via the display unit 25 of the passenger terminal 2 (see Figure 8).

[0041] If the positioning status determination unit 32d determines that positioning is poor, and then returns to determining that positioning is good, the traveled route display unit 32g may perform a route search (for example, a search for the shortest route or the optimal route) for the section where positioning was poor, based on the vehicle's position information and map information immediately before and after the section where positioning was poor, and display the route obtained by the route search as the traveled route for the section where positioning was poor on the passenger terminal 2. The fare display unit 32c may also display the fare 50 calculated based on the route obtained by the route search on the passenger terminal 2 (see Figure 9).

[0042] As one variation, if the positioning status determination unit 32d determines that positioning is poor, and then returns to determining that positioning is good, the traveled route display unit 32g may perform map matching to match the vehicle's position information for the section where positioning was poor with nearby roads obtained from map information, and display the route obtained by map matching as the traveled route for the section where positioning was poor on the passenger terminal 2. The fare display unit 32c may also display the fare 50 calculated based on the route obtained by map matching on the passenger terminal 2.

[0043] (An example of operation) Next, an example of the operation of the information processing system 1 will be described with reference to Figure 2. Figure 2 is a flowchart showing an example of the operation of the information processing system 1.

[0044] As shown in Figure 2, first, when the vehicle starts operating with passengers on board, the location information acquisition unit 32a of the soft meter terminal 3 acquires the vehicle's current location information using the positioning information from the positioning unit 34 (step S10). For example, the location information acquisition unit 32a acquires the vehicle's current location information based on positioning information from radio navigation means such as GPS or QZSS. The location information acquisition unit 32a may also use positioning information from autonomous navigation means such as acceleration sensors or geomagnetic sensors for further positioning. The vehicle's location information acquired by the location information acquisition unit 32a is stored in the positioning information database 33c along with time information and positioning reliability information.

[0045] Next, the positioning status determination unit 32d determines whether the positioning status is good or bad based on the vehicle's location information acquired by the location information acquisition unit 32a (step S11).

[0046] Then, if the positioning status determination unit 32d determines that positioning is good (step S12: YES), the fare calculation unit 32b refers to the map information database 33b and the positioning information database 33c, measures the vehicle's travel distance based on the vehicle's location information and map information, and calculates the fare (step S13).

[0047] Next, the fare display unit 32c displays the fare calculated by the fare calculation unit 32b via the display unit 35, and transmits a control signal to the passenger terminal 2 to display the fare, and as shown in Figure 4, the fare 50 is displayed to the passenger via the display unit 25 of the passenger terminal 2 (step S14).

[0048] On the other hand, if the positioning status determination unit 32d determines that positioning is inaccurate (step S12: NO), the positioning inaccurate information display unit 32e transmits a control signal to the passenger terminal 2 to display information regarding the uncertainty (variability) of the displayed fare, and displays it to the passenger via the display unit 25 of the passenger terminal 2 (step S16). For example, as one way of displaying information regarding the uncertainty (variability) of the displayed fare, the positioning inaccurate information display unit 32e may gray out the display of the fare 50, as shown in Figure 5. Alternatively, as another way of displaying information regarding the uncertainty (variability) of the displayed fare, the positioning inaccurate information display unit 32e may display a string 52 indicating that the fare is uncertain (variable), as shown in Figure 6. In this way, when the positioning status is determined to be inaccurate, information regarding the uncertainty (variability) of the displayed fare is displayed on the passenger terminal 2, so that the passenger can know that the currently displayed fare is inaccurate (may vary). As a result, even if the displayed fare suddenly changes significantly after the positioning system recovers, passengers will not be as surprised or anxious because they already know that the fare displayed immediately before was inaccurate. Therefore, it is possible to reduce passenger distrust of meter displays using soft meters.

[0049] Next, the fare display unit 32c stops updating the fare display on the passenger terminal 2 (i.e., the fare display is no longer updated) until it returns to a determination that the positioning is good (i.e., until it proceeds in the direction of YES at the branching in step S12) (step S17). By preventing the fare display on the passenger terminal 2 from being updated, it is possible to prevent the fare display from being incorrectly changed based on location information with poor positioning accuracy when the positioning status is determined to be poor, which could cause passengers to lose faith in the meter display.

[0050] As one variation, referring to Figure 3, instead of step S17, the fare display unit 32c may calculate the estimated fare by calculating the distance traveled based on map information and / or road images taken by the vehicle's camera, and display the calculated estimated fare 51 as a guideline fare on the passenger terminal 2, as shown in Figure 6 (step S19).

[0051] Next, the fare display unit 32c displays information indicating that the fare is being added on the display units 35 of the passenger terminal 2 and the soft meter terminal 3 (step S18). This allows passengers to know that the fare is continuing to be added even if the fare display update on the passenger terminal 2 has stopped (or if an estimated fare is displayed and the actual fare is not displayed), preventing the misunderstanding that the fare addition has also stopped because the fare display update on the passenger terminal 2 has stopped (or the fare is not displayed). After that, the control unit 32 returns to step S10.

[0052] In step S14, the fare display unit 32c displays the fare calculated by the fare calculation unit 32b on the display units 35 of the passenger terminal 2 and the soft meter terminal 3. Then, the advance notice display unit 32f refers to the map information database 33b and the positioning information database 33c and detects in advance that the vehicle will enter a predetermined positioning failure area (for example, a tunnel) based on the vehicle's location information, map information, and / or road images captured by the vehicle's camera. The advance notice display unit 32f then displays information 53 regarding the uncertainty of the displayed fare on the passenger terminal 2 in advance, as shown in Figure 7 (step S15). This allows passengers to know in advance that the displayed fare will soon become inaccurate (may fluctuate).

[0053] Even if the advance warning display unit 32f has detected in advance that a vehicle is entering a positioning failure area, the fare display unit 32c may display information 54 on the passenger terminal 2 indicating that fare accrual will continue, as shown in Figure 7. This allows passengers to know that fare accrual will continue even if the fare display on the passenger terminal 2 stops updating, preventing the misunderstanding that fare accrual will also stop when the fare display on the passenger terminal 2 stops updating.

[0054] Next, the traveled route display unit 32g refers to the map information database 33b and the positioning information database 33c and identifies the vehicle's traveled route based on the vehicle's location information and map information. Then, the traveled route display unit 32g transmits a control signal to the passenger terminal 2 to display the traveled route, and as shown in Figure 8, the traveled route 55 is displayed on the map via the display unit 25 of the passenger terminal 2 (step S21).

[0055] If the positioning status determination unit 32d determines that positioning is poor, and then returns to determining that positioning is good (i.e., after repeating the loop of steps S10→S11→S12→S16→S17→S18→S11 once or more times, the system proceeds in the order of steps S10→S11→S12→S13→S14→S15→S21→S22 for the first time), the traveled route display unit 32g refers to Figure 8 and, based on the vehicle's position information and map information immediately before and after the section 56 where positioning was determined to be poor, performs a route search (for example, a search for the shortest route or the optimal route) for the section where positioning was determined to be poor. As shown in Figure 9, the route 57 obtained by the route search is displayed on the passenger terminal 2 as the traveled route for the section where positioning was determined to be poor (step S22).

[0056] As one variation of step S22, the traveled route display unit 32g may, referring to Figure 8, perform map matching to match the vehicle's position information for section 56, which was determined to have poor positioning, with nearby roads obtained from map information, and as shown in Figure 9, display the route 57 obtained by map matching as the traveled route for the section that was determined to have poor positioning on the passenger terminal 2.

[0057] If the passenger terminal 2 is displayed with an incomplete route, it could cause anxiety among passengers. However, by supplementing the route for section 56, which was previously determined to have poor positioning, through route search and map matching, the completed route can be displayed, preventing passengers from feeling anxious.

[0058] If the positioning status determination unit 32d determines that positioning is poor, and then returns to determining that positioning is good, the traveled route display unit 32g may display the traveled route, which has been supplemented by route search and map matching, to the passenger via the passenger terminal 2 (step S22), and the fare display unit 32c may display the fare 50 calculated based on the supplemented traveled route to the passenger via the passenger terminal 2.

[0059] Subsequently, the control unit 32 of the soft meter terminal 3 determines whether the vehicle has arrived at its destination. If it has arrived, the process ends. On the other hand, if the vehicle has not arrived at its destination, the control unit 32 returns to step S10.

[0060] According to the embodiment described above, if the vehicle's location information is determined to be inaccurate, information regarding the uncertainty (variability) of the displayed fare is displayed on the passenger terminal 2. This allows the passenger to know that the currently displayed fare is inaccurate (may fluctuate). As a result, even if the displayed fare suddenly changes significantly after the positioning situation is restored, the passenger will not be as surprised or anxious because they know that the fare displayed immediately before was inaccurate. Therefore, it is possible to reduce the distrust that passengers have towards meter displays using soft meters.

[0061] Furthermore, at least a part of the information processing system 1 described in the above-mentioned embodiment may be configured as hardware or as software. In the case of hardware configuration, a program that realizes at least a part of the functions of the information processing system 1 may be stored on a recording medium such as a flexible disk or CD-ROM, and loaded into a computer for execution. The recording medium is not limited to removable ones such as magnetic disks or optical disks, but may also be a fixed recording medium such as a hard disk drive or memory.

[0062] Furthermore, a program that implements at least some of the functions of Information Processing System 1 may be distributed via communication lines such as the Internet (including wireless communication). In addition, the program may be encrypted, modulated, or compressed and distributed via wired or wireless lines such as the Internet, or stored on a recording medium.

[0063] Furthermore, the information processing system 1 may be made to function by one or more information processing devices. When multiple information processing devices are used, one of the information processing devices may be a computer, and the computer may execute a predetermined program to realize the function of at least one means of the information processing system 1.
