Description

The present invention relates to a taximeter system, a taximeter and a portable wireless terminal.

Currently, taxi fares are determined based on the distance and time of boarding, except in special cases, so they are not fixed until the taxi vehicle actually arrives at the destination. Therefore, when using a taxi in an unfamiliar land or an unfamiliar land, the taxi user may feel uneasy because he / she does not know the fare in advance.

On the other hand, the Ministry of Land, Infrastructure, Transport and Tourism has announced a policy to introduce a "fare pre-determination service" that allows taxi fare to be confirmed before boarding in FY2017.

As a prior art, the taxi fare is calculated before the fare determination device arrives at the destination, and the calculated taxi fare is determined as the taxi fare to be paid by the user. Patent Document 1 discloses a taxi fare predetermining system that does not change the fare.

Further, in Patent Document 2, the cheapest route information obtained by the actual machine simulator and the cheapest route information obtained by the verification simulator are compared, and the comparison result is output to verify the validity of the boarding fee. The boarding fee verification system is disclosed.

Further, in Patent Document 3, by interlocking the touch panel and the taximeter, even if the taximeter is installed at a position away from the driver's seat, the taxi driver can easily operate the taximeter by operating the touch panel. An operable taximeter device is disclosed.

Further, in Patent Document 4, when a payable amount for using a taxi is specified, the input amount is subtracted from the charge data taken from the taximeter to obtain the remaining amount, and the mileage based on the remaining amount is obtained. A toll management device that asks for and displays the found mileage is disclosed.

The meter charge information includes the fare and the state of the taximeter 10 (hereinafter referred to as the meter state).

The taximeter 10 includes a CPU 11, a ROM 12, a RAM 13, a card reader / writer (R / W) interface (I / F) 14, a communication unit 24, a display unit 15, an input unit 16, and an interface (I / F) 17A, 17B, RTC. It has a (clock IC) 18 and a navigation 22. A GPS receiver 20 is connected to the I / F17A. The ETC on-board unit 19 is connected to the I / F17B.

The CPU 11 controls the overall operation of the taximeter 10. The CPU 11 has a built-in input port for inputting a vehicle speed pulse signal or the like indicating the speed of the vehicle. The vehicle speed pulse signal is a signal output according to the rotation of the wheel. The CPU 11 calculates the fare from the mileage obtained from the vehicle speed pulse signal and the mileage measured by the RTC 18. During normal renting, the CPU 11 increases the charge when the mileage or the traveling time reaches a certain value. Further, when the expressway is rented, the CPU 11 stops the charge based on the travel time and only increases the charge based on the travel distance (charge increase). Similarly, under specific conditions such as when waiting for passengers, the CPU 11 may stop charging based on the mileage and only increase the charging based on the traveling time.

Further, the CPU 11 accepts the selection of various buttons as the input of the tariff. For example, when the actual vehicle button b2 is selected, the CPU 11 calculates the fare at the time of renting and displays the taxi fare screen during renting on the display unit 15. Further, when the high-speed button b11, the premium button b12, the discount button b15, or the like is selected, the CPU 11 can display the meter status of the high-speed, premium, discount, etc. on the taxi fare screen (see FIG. 4).

The ROM 12 stores a basic control program of the taximeter 10, a charge master file used for charge calculation, and the like. The RAM 13 is used as a working memory when the CPU 11 executes various programs.

A memory card 14A, which is possessed by a crew member and is used to read and write various data, is freely inserted and removed from the card reader / writer (R / W) interface (I / F) 14. As the memory card 14A, a memory card such as an SD card or a CF (registered trademark) card that reads / writes by contact, an IC card or a magnetic card that can read / write without contact is used.

In the present embodiment, the display unit 15 and the input unit 16 are integrally composed of the touch panel TP1. When the touch panel is used, the taximeter 10 receives the input information when the crew presses various buttons displayed on the touch panel TP1. The display unit 15 and the input unit 16 may be separate electronic components. In this case, the display unit is composed of a display device such as a liquid crystal display (LCD), an organic EL, a plasma display, and an LED. Further, the input unit is composed of an input device such as a touch sensor, a touch pad, a mouse, a keyboard, and a trackball.

The navigation 22 draws the current position with a marker on the map displayed on the display unit 15 based on the GPS position information of the taxi vehicle 8 during traveling, displays input items for navigation, and inputs the input unit 16. It has a function to guide the route to the destination entered in. Here, the navigation 22 is only displayed on the display unit 15, but if it has a voice output function, voice guidance may be output from the speaker or earphone terminal. Further, the navigation 22 may have a display unit capable of displaying a navigation screen separately from the display unit 15.

On the other hand, the smartphone 50 has a CPU 51, a memory 52, a communication unit 53, an operation unit 54, a display unit 55, and an audio input / output unit 56. The CPU 51 comprehensively controls each part of the smartphone 50.

The communication unit 53 has functions of short-range wireless (for example, BLE, Bluetooth (registered trademark), ZigBee (registered trademark)) and wireless LAN as narrow-range communication, and can communicate with the taxi meter 10. Further, the communication unit 53 has a mobile communication function, transmits / receives control data to / from a radio base station, and performs protocol control such as calling and incoming calls according to a control protocol.

The operation unit 54 includes a numeric keypad and various function buttons. The display unit 55 displays various information such as a map and meter charge information. In the present embodiment, the operation unit 54 and the display unit 55 are composed of the touch panel TP2. The operation unit 54 and the display unit 55 may be composed of separate electronic components.

The operation of the taximeter system 5 having the above configuration is shown. FIG. 2 is a flowchart showing the operation procedure of the taximeter 10. The CPU 11 of the taximeter 10 periodically executes this operation program. The CPU 11 of the taximeter 10 performs a wireless connection process when a passenger gets on board and receives a wireless connection request from the smartphone 50 possessed by the passenger (S1). As described above, the wireless connection is made by short-range wireless or wireless LAN. If there is no wireless connection request from the smartphone 50, the CPU 11 waits until there is a wireless connection request. Further, once the wireless connection is made, the passenger cuts off the connection of the smartphone 50, or when the smartphone 50 goes out of the wireless communication range of the taximeter 10, the wireless connection is cut off. Examples of the operation of disconnecting the connection include terminating the taxi use application and pressing the blocking button.

When the wireless connection is made, the CPU 11 transmits the current meter charge information (fare and meter status) to the smartphone 50 (S2). The CPU 51 determines whether or not the payment button b3 is pressed (S3). If the payment button b3 is not pressed, the CPU 51 returns to the process of step S2. On the other hand, when the payment button b3 is pressed, the CPU 51 transmits the payment information of the taximeter fee to the smartphone 50 (S4). This payment information includes taximeter fare information in which the fare calculated based on the mileage and time is adjusted according to the meter status (high speed, premium, discount, etc.).

Then, the CPU 11 determines whether or not the pre-determined charge information has been received from the smartphone 50 (S5). If the pre-determined charge information has not been received, the CPU 11 ends this operation. On the other hand, when the pre-determined fare information is received in step S5, the CPU 11 rewrites the taximeter fare based on the pre-determined fare information (S6). Here, the pre-determined fare information includes information including the predicted fare obtained as a result of starting the taxi use application before the taxi user uses the taxi (before boarding) and performing the route search process of the taxi use application. Is. In addition to the predicted fare, the taxi user may include the meter status such as "discount" in the pre-determined fare information so that the disabled person discount is applied in the case of a disabled person.

When the taximeter charge is rewritten, the CPU 11 transmits the charge rewrite confirmation information to the smartphone 50 (S7). After this, the CPU 11 ends this operation.

Subsequently, the operation of the smartphone 50 will be shown.
(Operation of taxi users before boarding)
Before boarding, the taxi user searches for a route using the smartphone 50 in which the taxi use application is installed in advance. FIG. 3 is a flowchart showing the operation procedure of the smartphone 50 before boarding. The CPU 51 of the smartphone 50 activates the taxi use application when the taxi use icon displayed on the home screen of the display unit 55 is touch-operated by the taxi user. The taxi use application determines whether or not there is a taximeter belonging to the communicable range. The presence or absence of a taximeter may be instructed by the taxi user to the taxi use application by operating a button, or the taxi use application may broadcast a wireless connection request and judge by itself depending on the presence or absence of the response.

Before boarding, the CPU 51 of the smartphone 50 performs a route search process (S21). The details of the route search process will be described later. After this, the CPU 51 ends this operation.

FIG. 4 is a flowchart showing the route search processing procedure in step S21. The CPU 51 waits until the route search operation is performed by the taxi user (S31). In this route search operation, information including the current location, the destination, and various conditions (for example, high speed possible, time priority, charge priority, congestion avoidance, waypoint designation, etc.) is input.

When the route search operation is performed, the CPU 51 performs a route search based on the information input by the taxi user, and outputs the route (guidance route), distance, time, predicted fare, etc. as a search result (S32). .. The route search result is displayed on the screen of the taxi use application. The CPU 51 holds the route search result in the memory 52 (S33). After this, the CPU 51 ends this operation.

(Operation of taxi users while riding)
FIG. 5 is a flowchart showing the operation procedure of the smartphone 50 while riding. The CPU 51 of the smartphone 50 performs wireless connection processing with the taximeter 10 (S41). The details of the wireless connection process will be described later.

The CPU 51 determines whether or not the route search result is held in the memory 52 (S42). When the route search result is held in the memory 52, the route search result when the taxi user performs the route search before boarding and the result is held in the memory 52, and when the taxi is used before. Is held in the memory 52.

When the route search result is held in the memory 52, the CPU 51 proceeds to the process of step S44. On the other hand, when the route search result is not held in the memory 52, the CPU 51 performs the route search process (S43). This route search process is the same as the route search process of FIG. 4 described above.

The CPU 51 performs reception data display processing for receiving meter charge information and payment information from the taximeter 10. (S44). The details of the received data display processing will be described later. The CPU 51 performs a fare comparison process of comparing the pre-determined fare acquired before boarding with the actual taximeter fare (S45). After this, the CPU 51 ends this operation. The details of the charge comparison process will be described later.

FIG. 6 is a flowchart showing the wireless connection processing procedure in step S41. The CPU 51 of the smartphone 50 determines whether or not it is wirelessly connected to the taximeter 10 (S51). When wirelessly connected to the taximeter 10, the CPU 51 ends this operation as it is.

On the other hand, when the taximeter 10 is not wirelessly connected, the CPU 51 determines whether the setting stored in the memory 52 is an automatic connection or a manual connection (S52). In the case of manual connection, the CPU 51 waits until the connection operation is performed by the passenger (S53). Examples of the connection operation include pressing the wireless connection button displayed on the screen of the taxi use application of the smartphone 50.

When the connection operation is performed, the CPU 51 executes the wireless connection process (S54). As described above, the wireless connection is performed by short-range wireless communication or wireless LAN. For short-range wireless communication, for example, when Bluetooth (registered trademark) is used, the smartphone 50 and the taximeter 10 are paired. Further, in the case of wireless LAN, the smartphone 50 sets the SSID (Service Set Identifier) and the encryption key of the network to which the taxi meter 10 is connected. Further, in the case of automatic connection in step S52, the CPU 51 proceeds to step S54 without waiting for the passenger connection operation. After this, the CPU 51 ends this operation.

FIG. 7 is a flowchart showing the received data display processing procedure in step S44. The CPU 51 determines whether or not the current meter charge information (fare and meter state) has been received from the taximeter 10 (S61). Upon receiving the meter fare information, the CPU 51 updates the taxi fare screen GM2 displayed as a window on the touch panel TP2 (S62). The updated fare and meter status (next fare increase rate bar, etc.) are displayed on the taxi fare screen GM2. On the other hand, when the meter charge information is not received in step S61, the CPU 51 determines whether or not the taximeter charge payment information has been received from the taximeter 10 (S63). If the payment information is not received, the CPU 51 returns to the process of step S61. On the other hand, when the payment information is received, the CPU 51 ends this operation.

FIG. 8 is a flowchart showing the charge comparison processing procedure in step S45. The CPU 51 compares the taximeter charge received from the taximeter 10 with the pre-determined charge (S71). As a result of the comparison, it is determined whether or not the taximeter charge is higher than the predetermined charge (S72). When the taximeter charge is higher than the predetermined charge, the CPU 51 transmits the predetermined charge to the taximeter 10 (S73).

Then, the CPU 51 determines whether or not the charge rewriting confirmation information has been received from the taximeter 10 (S74). When the taximeter charge is rewritten by the taximeter 10, the charge rewrite confirmation information is transmitted from the taximeter 10 to the smartphone 50. If the CPU 51 of the smartphone 50 has not received the charge rewriting confirmation information, the process returns to step S73 and repeats the process of transmitting the pre-determined charge. When the charge rewriting confirmation information is received in step S74, the CPU 51 ends this operation as it is. Passengers can settle the taximeter fare at a pre-determined fare. For example, even if the fare becomes high due to sudden traffic jams, passengers can settle the taximeter fare with a pre-determined fare, so they can take a taxi with peace of mind, and as a result, the use of taxis will increase. It leads to.

On the other hand, if the taximeter charge is the same as or lower than the predetermined charge in step S72, the CPU 51 ends the operation as it is. If the taximeter fare is cheaper than the pre-determined fare, passengers can settle the taximeter fare with the taximeter fare that remains low. Therefore, passengers can feel cheap and lead to an increase in taxi use. If the taximeter charge is lower than the pre-determined charge, the taximeter charge may be aligned with the pre-determined charge, and the taximeter charge can be made uniform. In this case, the driver's sales can be stabilized.

The pop screen pp1 includes the time, distance, and estimated fare for traveling from the current position to the destination along the route R1. Here, the time is "16 minutes", the distance is "6.1 km", and the predicted fare is "2,170 yen".

FIG. 10B shows a display screen of the touch panel TP2 while riding. On the touch panel TP2, in addition to the pop screen pp1, the taxi fare screen GM2 is displayed as a window. On the taxi fare screen GM2, the fare and the next fare increase rate bar br1 are displayed. Here, the amount of 2,170 yen is displayed as the fare.

The taximeter system 5 according to the first embodiment of the present invention includes a taximeter 10 and a smartphone 50 (portable wireless terminal). The taximeter 10 includes a communication unit 24 that wirelessly communicates with the smartphone 50, and the smartphone 50 has a CPU 51 (predetermined unit) that predetermines the taximeter charge (fare) to the destination, and a taximeter 10 and wirelessly. A communication unit 53 (terminal-side communication unit) for communicating is provided. The communication unit 53 can transmit the fare fixed by the CPU 51 to the taximeter 10, and the CPU 11 outputs the lower fare of the calculated fare and the fixed fare as the final fare. As a result, the fare paid by the passenger can be prevented from exceeding the fare fixed before boarding. Therefore, when using a taxi in an unfamiliar land or an unfamiliar land, the upper limit of the fare can be known before boarding (in advance), so that the taxi user can use the taxi with peace of mind. In addition, foreign tourists, who have been increasing in recent years, can also use taxis with peace of mind. As a result, the use of taxis is expected to increase.

Further, the communication unit 24 transmits the fare calculated at the destination to the smartphone 50, and the smartphone 50 determines which of the fare calculated by the CPU 11 and the fare determined by the CPU 51 is cheaper. Part). When the communication unit 53 determines that the fare determined by the CPU 51 is lower than the fare calculated by the CPU 11, the communication unit 53 transmits the determined fare to the taximeter 10, and the CPU 11 transmits the received fare. Output as the final fare. As a result, when the pre-determined fare is cheaper than the taximeter fare at the time of renting, the smartphone automatically sends the pre-determined fare, which can reduce the time and effort of passengers. Further, when the pre-determined fare is higher than the taximeter fare at the time of renting, the smartphone does not send the pre-determined fare to the taximeter, so that the rewriting process by the taximeter can be omitted. Further, in this case, the taximeter fee to be paid is cheaper than the predetermined fee, so that the passenger's cost is reduced. This is expected to increase the use of taxis.

Further, the communication unit 24 of the taximeter 10 and the communication unit 53 of the smartphone 50 are directly connected by short-range wireless communication (narrow area communication). As a result, the portable wireless terminal requires only the electric power required for narrow-range communication in connection with the taximeter, so that the electric power consumption can be suppressed. In particular, when BLE communication with low power consumption is used, it is possible to further reduce the power consumption. Therefore, even if the mobile wireless terminal is continuously connected to the taximeter while the taxi is on board, it is possible to prevent the battery drive time of the mobile wireless terminal from being significantly shortened. In addition, since communication is performed directly without going through other devices, the delay time required to display or update the fare information can be shortened.

The taximeter 10 according to the first embodiment of the present invention includes at least a CPU 11 (calculation unit) having a function of calculating a fare, and a communication unit 24 that wirelessly communicates with an external smartphone 50. The communication unit 24 transmits the fare calculated at the destination to the smartphone 50, and when the CPU 11 acquires the information representing the fare from the smartphone 50 at the destination, the calculated fare and the smartphone 50 determine the fare. The lower fare of the fare is output as the final fare. This makes it possible to prevent the final taximeter fare displayed on the taximeter from exceeding the fare fixed before boarding.

The smartphone 50 according to the first embodiment of the present invention includes a CPU 51 (predetermined unit) that predetermines the fare to the destination, a communication unit 53 (terminal side communication unit) that wirelessly communicates with the taximeter 10. When information representing a fare is received from the taximeter 10, the CPU 51 (determination unit) for determining which of the received fare and the fare determined by the CPU 51 is cheaper is provided. When the communication unit 53 determines that the fare determined by the CPU 51 is cheaper than the received fare, the communication unit 53 transmits the determined fare to the taximeter 10. As a result, the taximeter can display the fare suppressed so as not to exceed the fare fixed before boarding.

The technical scope of the present invention is not limited to the above-described embodiment. The above-described embodiments can be accompanied by various modifications, improvements, and the like within the technical scope of the present invention.
For example, the mobile wireless terminal is not limited to a smartphone, but may be a tablet terminal, a notebook PC, or the like.

Further, in the above embodiment, the case where the smartphone performs the comparison between the taximeter charge charged by the taximeter and the pre-determined charge acquired by the smartphone is shown, but the taximeter may perform the comparison. In this case, the taximeter receives the pre-determined charge information from the smartphone when it is wirelessly connected to the smartphone. The taximeter determines whether or not the taximeter fare exceeds the pre-determined fare during renting or at the time of payment, and if so, rewrites the taximeter fare to the pre-determined fare.

In addition, if the pre-determined fare is sent to the taximeter during the rent, the taximeter can display the pre-determined fare on the taxi fare screen GM0 during the rent, so that the passenger can go to the destination. You can feel at ease until you arrive at.

Further, in the above embodiment, when the taximeter charge is lower than the predetermined charge, the taximeter charge is not rewritten, but may be rewritten to the predetermined fixed charge. In this case, the taximeter fare that is charged sequentially will not be used as the fare to be paid, and the taximeter fare (fare) will be fixed at the time of boarding. As a result, neither the crew nor the passengers have to worry about the taximeter fee charged. Therefore, the driver can concentrate on driving and the passengers can take a taxi in a relaxed state.

(Second Embodiment)
The configuration of the taximeter system in the second embodiment is the same as the configuration of the taximeter system 5 of FIG. 1 described above. In the second embodiment, the difference from the first embodiment is that in the smartphone 50, the operation unit 54 (input unit) accepts the input operation of the budget amount, and the CPU 51 (point calculation unit) can reach the input budget amount. The point on the route is calculated, and the display unit 55 displays the calculated point. Further, the CPU 51 (point determination unit) determines the point as the destination. Further, the CPU 51 (predetermined unit) predetermines the fare to the confirmed point. The communication unit 53 (terminal-side communication unit) can transmit the fare to the point to the taximeter 10 as the fare determined by the CPU 51.

The operation of the taximeter system 5 according to the second embodiment having the above configuration is shown.

First, the operation of the smartphone 50 will be shown.
(Operation of taxi users before boarding)
FIG. 11 is a flowchart showing the operation procedure of the smartphone before boarding. As described in the first embodiment, the taxi use application is installed in the smartphone 50 in advance.

Before boarding the taxi user, the CPU 51 of the smartphone 50 performs a route search process (S81). The route search process S81 is the same as the route search process S21 described with reference to FIG. After the route search process (S81), the CPU 51 performs a budget determination process (S82). The details of the budget judgment process will be described later. After this, the CPU 51 ends this operation.

FIG. 12 is a flowchart showing the budget determination processing procedure in step S82. The CPU 51 determines whether or not the budget button B1 shown in FIG. 15A is pressed (S91). FIG. 15 is a diagram showing a display screen of the touch panel TP2 of the smartphone 50 according to the second embodiment. FIG. 15A shows an example in which the budget button B1 is displayed on the touch panel TP2. On the touch panel TP2, as described with reference to FIG. 10A, the route R2 determined by the route search of the taxi use application is drawn on the map mp1, and the budget button B1 is superimposed on the left corner. ing. If the budget button B1 is not pressed (NO in S91), the CPU 51 ends this operation. On the other hand, when the budget button B1 is pressed (YES in S91), the CPU 51 causes the touch panel TP2 to display the budget selection screen as shown in FIG. 15B. In FIG. 15B, the touch panel TP2 displays a cash button B2 and an electronic money button B3 as a budget selection screen.

When the budget button B1 is pressed (YES in S91), the CPU 51 determines which of the cash button B2 and the electronic money button B3 is pressed (S92). When the cash button B2 is pressed, the CPU 51 causes the touch panel TP2 to display the cash payment input screen G1 (S93). FIG. 16A is a diagram showing a cash payment input screen G1 displayed on the touch panel TP2. The cash payment input screen G1 is displayed as a window on the touch panel TP2, and has an amount display field c1 for displaying the amount input by the user, a numeric keypad tk for inputting numbers, and "return" and "back". It has operation buttons k1 and k2 for performing the operation of "decision". The user presses the numeric keypad tk and the operation buttons k1 and k2, and inputs the budget amount (S94). The entered amount is displayed in the amount display field c1. On the other hand, when the electronic money button B3 is pressed, the CPU 51 causes the touch panel TP2 to display the electronic money payment input screen G2.

FIG. 16B is a diagram showing an electronic commerce payment input screen G2 displayed on the touch panel TP2. The electronic money payment input screen G2 is displayed as a window on the touch panel TP2, and is similar to the cash payment input screen G1, but instead of the amount display field c1, the charge amount field c2 and the payment amount field c3 are displayed. It is different from the cash payment input screen G1 in that it has. The available electronic money balance is displayed in the charge amount column c2 (S95). The user presses the numeric keypad tk and the operation buttons k1 and k2, and inputs a budget amount that does not exceed the electronic money balance displayed in the charge amount column c2 (S96). The entered amount is displayed in the payment amount field c3.

When the budget amount is input by the user (S94, S96), the CPU 51 calculates a point on the route R2 that can be reached by the input budget amount and displays it on the touch panel TP2 (S97). FIG. 17 shows an example of a screen displayed on the touch panel TP2 that displays the point P on the route R2 that can be reached with the input budget amount. FIG. 17A shows an example of a display screen before the user gets on the taxi, and FIG. 17B shows an example of the display screen while the user is on the taxi.

As shown in FIG. 17A, on the display screen before the user gets on the taxi, the pop screens pp2 and pp3 are displayed on the map mp1 in addition to the route R2. The pop screen pp2 includes the time, distance and estimated fare for traveling from the current position to the destination along the route R2. Here, the time is "17 minutes", the distance is "5.2 km", and the predicted fare is "2,170 yen". The pop screen pp3 is displayed at a position indicating a point O on the route R2 that can be reached with the input budget amount. Here, the reachable point P when 2000 yen is input as the budget amount is displayed on the touch panel TP2. In step S97, the CPU 51 (predetermined unit) determines the point P as the destination, and determines the fare to the determined point P in advance. Then, the CPU 51 holds the input budget and the point P (reachable point) determined as the destination in the memory 52. After this, the CPU 51 ends this operation.

The CPU 51 is selected by displaying a plurality of points on the route R2 on the touch panel TP2 as reachable points with a budget amount and selecting one point from the plurality of displayed points by a touch operation. The point may be determined as the destination. In this case, the destination can be set near a point that can be reached with the budget amount, such as a station or a bus stop, and the user can easily move to the original destination even after getting off the taxi.

(Operation of taxi users while riding)
FIG. 13 is a flowchart showing the operation procedure of the smartphone 50 while riding in the second embodiment. The CPU 51 of the smartphone 50 performs wireless connection processing with the taximeter 10 (S101). The wireless connection process (S101) is the same as the wireless connection process of FIG. 6 described above. The CPU 51 determines whether or not the route search result is held in the memory 52 (S102). This discrimination process (S102) is the same as the process in step S42 of FIG. 5 described above. When the route search result is held in the memory 52, the CPU 51 proceeds to the budget transmission process in step S104. On the other hand, when the route search result is not held in the memory 52, the CPU 51 performs the route search process (S103). This route search process (S103) is the same as the route search process of FIG. 4 described above.

The CPU 51 performs a budget transmission process of transmitting the fare to the point P determined in step S97 of FIG. 12 to the taximeter 10 as the fare determined in advance (predetermined charge) (S104). The details of the budget transmission process will be described later.

After that, the CPU 51 performs a reception data display process for receiving meter charge information and payment information from the taximeter 10. (S105). The received data display process is the same as the received data display process of FIG. 7 described above. The CPU 51 causes the touch panel TP2 to display a screen showing a point P on the route R2 that can be reached with a budget amount, as shown in FIG. 17B. In FIG. 17B, the mark M indicating the current position of the own taxi is displayed on the screen shown in FIG. 17A, and the taxi fare screen GM3 is displayed as a window. The current meter fare information (fare and meter status) received from the taximeter 10 is displayed on the taxi fare screen GM3. Subsequently, the CPU 51 performs a fare comparison process for comparing the pre-determined fare acquired before boarding with the actual taximeter fare (S106). The charge comparison process (S106) is the same as the charge comparison process of FIG. 8 described above, but in the second embodiment, the fare to the point P determined in step S97 of FIG. 12 is used as the pre-determined charge. After this, the CPU 51 ends this operation.

FIG. 14 is a flowchart showing the budget transmission processing procedure in step S104. The CPU 51 of the smartphone 50 determines whether the budget has been input, that is, whether the input budget and the point P (reachable point) determined as the destination are held in the memory 52 (S111). When the budget is input (YES in S111), the CPU 51 transmits the budget and the reachable point (point P) held in the memory 52 to the taximeter 10 (S112), and ends this operation. On the other hand, when the budget is not input (NO in S111), the CPU 51 ends this operation as it is.

As described above, the taximeter system 5 according to the second embodiment of the present invention includes a taximeter 10 and a smartphone 50 (portable wireless terminal). In the smartphone 50, the CPU 51 (point calculation unit) calculates the reachable points on the route with the budget amount input by the operation unit 54 (numeric keypad tk), and the display unit 55 displays the calculated points. do. Further, the CPU 51 (point determination unit) determines this point as the destination, and the CPU 51 (predetermination unit) determines the fare to this point in advance (S97). Then, the fixed fare is transmitted to the taximeter 10 (S104). As a result, the user who intends to use the taxi can confirm the reachable point within the budget before boarding, so that it is possible to determine whether or not to use the taxi. On the other hand, as for the crew, since the reachable points within the passenger's budget are known in advance, for example, even if the passenger falls asleep while riding, the taxi continues to run beyond the passenger's budget and the passenger There is no shortage of fares paid by the crew, and the crew can safely carry the taxi.
