Description

  The present invention relates to an automatic toll collection system and an apparatus therefor, and more particularly, to an environment-friendly automatic toll collection system, a toll fee billing apparatus, and the like for performing appropriate charging for environment-friendly traveling on toll roads and highways. It relates to ETC onboard equipment.

Generally, tolls on expressways are determined for each type of vehicle such as ordinary vehicles, large vehicles, and light vehicles, and are not related to vehicle performance (fuel consumption, etc.). On the other hand, gasoline mileage of the vehicle is improved year by year, although emissions of C0 ₂ and N0x tend to be reduced, is the current situation is also equal toll in a vehicle environment-friendly with older types of vehicles .

On the other hand, the operation using the ETC (Electronic Toll Collection System) system on the expressway can be used for environmental driving like a discount system applied to large vehicles traveling on coastal areas (Wangan Line etc.) that have less impact on congestion and the environment. Corresponding discounts have been implemented. However, directed to a strictly traveling the travel route is environmentally friendly (alleviate congestion), and reduction of C0 ₂ and n0x, discount for travel in consideration of the environment itself has not been implemented.

  As described above, in the setting of tolls on conventional toll roads such as expressways, no discounts have been implemented for driving in consideration of the environment itself.

  The present invention has been made in view of the above-mentioned background, and an object thereof is to provide an automatic toll collection system, a toll fee charging apparatus, and an ETC on-board device that can be reflected in a toll fee in consideration of the vehicle performance. There is to do.

  In order to solve the above-mentioned problem, the automatic toll collection system according to the first aspect of the present invention is based on information stored in an IC card mounted on an ETC on-board device of a vehicle passing through an entrance gate and an exit gate of a toll road. In an automatic toll collection system that charges a fee, the gate identification information received from each gate when passing through the entrance gate and the exit gate and the fuel remaining information obtained from the vehicle at each time point are stored in the IC card. The standard toll and distance of the section are obtained by referring to a predetermined charge table based on the ETC in-vehicle device and the gate identification information stored in the IC card, and the determined distance and the fuel remaining stored in the IC card are stored. The average fuel consumption of the section is obtained based on the fuel consumption of the section obtained from the quantity information, and the standard toll is changed based on the obtained fuel consumption. And a charging means.

  In the present invention, by changing the standard toll based on the average fuel consumption of the toll section, eco-friendly driving can be encouraged, and the environment can be improved.

  In the second aspect of the present invention, the IC card further includes information on the remaining amount of fuel periodically acquired from the vehicle in the section from the entrance gate to the exit gate, and the toll fee charging means includes the IC card. The event indicating the vehicle driving content is determined based on the information on the fuel remaining amount stored in the vehicle, and the fuel consumption amount belonging to the driving event is extracted based on the determined event to determine the traveling fuel consumption of the section. The standard toll is changed based on the fuel consumption.

  In the present invention, the change in the remaining amount of fuel caused by a fueling event or a deoiling event in which the remaining amount of fuel changes abruptly is effectively observed by periodically monitoring the transition of the remaining amount of fuel in the middle of the section. It can be excluded, and it becomes possible to obtain an accurate travel fuel consumption of the section.

  A toll fee charging apparatus according to a third aspect of the present invention is an automatic toll collection system that charges a toll fee based on information stored in an IC card mounted on an ETC on-board unit of a vehicle passing through an entrance gate and an exit gate of a toll road. In the toll fee charging device, the information extraction means for obtaining the standard toll and distance of the section by referring to a predetermined toll table by each gate identification information of the entrance gate and the exit gate stored in the IC card, and the obtained Based on the distance and the fuel consumption amount of the section obtained from the fuel remaining amount of the vehicle at each passage time of the entrance gate and the exit gate stored in the IC card, the average fuel consumption of the section is obtained, and based on the obtained fuel consumption A toll changing means for changing the standard toll.

  In a fourth aspect of the present invention, the IC card further includes information on the remaining amount of fuel periodically acquired from the vehicle in the section from the entrance gate to the exit gate, and the toll change means includes the IC card. The event indicating the content of the vehicle travel is determined based on the remaining fuel information stored in the vehicle, and the fuel consumption belonging to the travel event is extracted based on the determined event to determine the travel fuel consumption of the section. The standard toll is changed based on the fuel consumption.

  In the fifth aspect of the present invention, the toll changing means determines that the fueling event has occurred because the remaining amount of fuel has increased by a predetermined amount within a predetermined time. This makes it possible to effectively distinguish between the fueling event and the traveling event.

  In a sixth aspect of the present invention, the toll changing means determines that the idling event has occurred because the remaining fuel amount has decreased within a predetermined time and greater than 0 and less than the first threshold. Thereby, an idling event and a running event can be distinguished effectively. Even if it is idling, a considerable amount of fuel is consumed when idling stops (rest) for a long time with heating and cooling, so the influence on the running performance cannot be ignored.

  In a seventh aspect of the present invention, the toll changing means decreases the fuel remaining amount within a predetermined time within a range from the first threshold value to a second threshold value that is greater than the first threshold value. It is determined as a running event. As a result, the actual running event in the section can be extracted effectively.

  In an eighth aspect of the present invention, the toll changing means determines that the oil removal event has occurred because the remaining amount of fuel has decreased beyond the second threshold value within a predetermined time. Thereby, a deoiling event and a running event can be distinguished effectively.

  In a ninth aspect of the present invention, the IC card further includes speed information periodically acquired from the vehicle in a section from the entrance gate to the exit gate, and the IC card stores the toll charge changing means. Judgment of event including information of speed to be performed.

  For example, when the speed is v = 0, it is possible to reliably determine the event of parking, stopping (including idling stop), refueling or deoiling. Further, for example, when the speed v is in the range of 1 to 20 km / h, it can be determined that the event is slow driving or traffic jam, and the deterioration of fuel consumption in the section can be understood. In addition, when the speed v is in the range of 40 km / h to 110 km / h, it can be determined that the vehicle is traveling in the normal ecology mode, and the core portion of the environment-friendly traveling can be extracted.

  In a tenth aspect of the present invention, the toll changing means compares the nominal travel fuel consumption of the vehicle stored in the IC card with the travel fuel consumption based on the determined travel event, and the nominal travel fuel consumption The standard toll is changed according to the deviation rate from Therefore, based on the nominal driving fuel consumption described in the catalog or the like, the driving performance in consideration of the environment by the driver is effective and can be evaluated fairly regardless of the difference in performance of the vehicle itself.

  In an eleventh aspect of the present invention, the ETC on-board device is an automatic toll collection system that charges a toll based on information stored in an IC card mounted on an ETC on-board device of a vehicle that passes through an entrance gate and an exit gate of a toll road. In the ETC on-board device, the IC card includes the identification information of the entrance gate and the information of the passage date and time notified from the gate when the entrance gate passes, and the information on the remaining amount of fuel of the vehicle acquired from the vehicle at the time. Recording means for storing, identification information of the inlet gate read from the IC card when passing through the outlet gate, information on the passage date and time, information on the remaining amount of fuel, and identification information of the outlet gate detected by the ETC on-board device Information of the passage date and time, the fuel remaining amount of the vehicle detected at that time, and the vehicle information registered in advance in the ETC on-board unit are sent to the roadside device of the exit gate. Transmitting means for transmitting.

  In a twelfth aspect of the present invention, the recording means further stores information on the remaining amount of fuel periodically acquired from the vehicle in the section from the entrance gate to the exit gate, and the transmission means reads from the IC card. Further information on the remaining amount of fuel from the entrance gate to the exit gate is transmitted.

  In the thirteenth aspect of the present invention, the vehicle information registered in the ETC on-board device includes one or more of information on engine displacement, engine type, fuel type, and environment-friendly vehicle type. Is included. As a result, it is possible to unconditionally preferentially pass an environment-friendly vehicle.

  According to the present invention, it is possible to provide an automatic toll collection system, a toll fee charging device, and an ETC in-vehicle device that can reflect the travel performance in consideration of the environment of the vehicle in the toll. As a result, it can be expected that by reducing the toll for driving eco-friendly vehicles, it will contribute to users and contribute to the improvement of the global environment, and will also accelerate the spread of environmentally friendly vehicles.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration of an environment-friendly road billing system according to an embodiment. For example, interchanges IC1 and IC2 on highways are provided with an entrance gate 20a and an exit gate 20b, which are connected to a central billing processing center 25 via a network (NW) 100.

  FIG. 2 shows a schematic configuration of the exit gate 20b. The exit gate 20b includes a gantry 1 installed so as to straddle the lane, and a roadside radio 2 that performs radio communication with the ETC vehicle-mounted device 30 of the vehicle 10 that is fixed to the top of the gantry 1 and passes through a predetermined area on the lane. Vehicle detectors 3 to 5 that detect the passage (intrusion and exit) of the vehicle 10 by a photoelectric sensor, a start controller 6 that performs opening / closing control of the passage gate 7, and controls these via the network 100. And a roadside device 21b connected online to the remote billing processing center 25. The same applies to the entrance gate 20a.

  3 and 4 show the configuration of the ETC vehicle-mounted device according to the embodiment. In general, the dashboard 12 of the vehicle 10 is already provided with a speedometer 12a, a fuel meter 12b, a mileage meter 12c, and the like. The fuel meter 12b indicates the remaining amount of fuel in the fuel tank 13 detected by the fuel sensor 14. indicate. In the present embodiment, this fuel remaining amount detection signal is also taken into the ETC vehicle-mounted device 30, and the transition of the remaining fuel amount sampled every predetermined time is recorded on the ETC card 40 as travel history information.

  The ETC vehicle-mounted device 30 is installed on, for example, a dashboard, and a radio communication unit 32 for wireless communication with the roadside wireless device 2 of the gate 20, its antenna 31, and main control / processing of the ETC vehicle-mounted device 30. Detected by the vehicle 10, a main memory (MM) 34 used by the CPU 33, a card accommodating portion (CHLD) 38 that detachably holds the ETC card 40, a card connection terminal (CN) 38 a, and the vehicle 10 An analog interface (AIF) 37 for selecting the remaining fuel amount and speed signals with an analog switch (ASW), A / D converting and taking them into the CPU 33, and a console (CSL) 35 operated by the user And a display unit 36 for displaying various information related to the ETC service.

  In addition to the application programs shown in FIGS. 5 and 6 executed by the CPU 33, the main memory 34 stores the ID number of the ETC on-vehicle device 30 and basic information of the vehicle 10 on which the ETC on-vehicle device 30 is mounted. I remember it. The basic information of this vehicle includes the type of vehicle and the registration number of the vehicle 10 as well as the displacement, engine type {(reciprocal engine / diesel engine / Various information such as rotary engine}, fuel type {gasoline (regular or high-octane) / light oil diesel / kerosene diesel / biodiesel}, environmentally friendly vehicle (hybrid car / fuel cell car / secondary battery car) Of these, information relating to the running performance of the vehicle is also used for a toll discount service at the billing processing center 25.

  Further, the ETC on-board device 30 includes a card insertion slot for inserting the ETC card 40. When the user inserts the ETC card 40 into the card insertion slot when getting on, the ETC on-board device 30 is connected to the ETC card 40. The card number is read and stored in the main memory 34. When the ETC card 40 is pulled out, the stored card number is cleared. Thereby, in this ETC onboard equipment 30, a plurality of different ETC cards 40 can be used.

  An example ETC card 40 (corresponding to the IC card of the present invention) is a credit card-sized plastic card in which an IC chip and a connection terminal (CN) 43 for connection to the ETC on-vehicle device 30 are embedded. is there. This IC chip includes a microprocessor unit (MPU) 41 that performs main control and processing of the ETC card 40 and a flash memory (FM) 42 used by the MPU 41. In addition to the card number for specifying the ETC card 40, the flash memory 42 stores in advance payment information such as the account number of the user deposit and the expiration date of the contract. Further, in this flash memory 42, as shown in FIG. 7, a travel history table 81 for recording a series of travel history information acquired from the passage of the input gate 20a to the passage of the exit gate 20b in time series. Is provided.

  With the above configuration, when the vehicle 10 passes through the entrance gate 20a, the CPU 33 receives information on the gate ID and the passage date and time notified from the gate 20a, and information on the remaining fuel amount acquired from the vehicle 10 at that time. Are recorded in the history table 81 of the ETC card 40. Preferably, information on the remaining amount of fuel periodically acquired from the vehicle quantity 10 is sequentially recorded in the history table 81 successively in the travel section from the entrance gate 20a to the output gate 20b. When the vehicle 10 passes through the exit gate 20b, the gate ID of the entrance gate 20a read from the history table 81, information on the passage date and time, information on the remaining fuel amount acquired from the vehicle 10 at the time, Information of the gate ID and passage date / time of the exit gate 20b received by the ETC on-board device 30, the remaining fuel amount acquired from the vehicle 10 at that time, and the travel history (remaining fuel amount) collected in the gate section of the entrance / exit And basic information of the vehicle registered in advance in the ETC vehicle-mounted device 30 is transmitted to the roadside device 21b of the exit gate 20b.

  The billing processing center 25 is provided with a toll table 82 shown in FIG. 11 and a rank table 83 for ranking the quality of driving fuel consumption shown in FIG. 12, and notified from the CPU 33 via the roadside device 21b. The standard toll of the vehicle 10 is obtained by the toll charge processing of FIG. 7 or FIG. 8 based on the passing information of the entrance / exit gates. At that time, the travel fuel consumption of the vehicle 10 is further calculated based on the travel history information. The fuel consumption is classified into rankings and reflected in the toll discount service. This will be described in detail below.

  FIG. 5 is a flowchart of the gate entry / exit process according to the embodiment, which is executed by the CPU 33 of the ETC vehicle-mounted device 30. In step S11, it waits for the vehicle 10 to enter the gate, and when it is detected, in step S12, it is determined whether or not the gate is the entrance gate 20a. In the case of the entrance gate 20a, the travel history table 81 of the ETC card 40 shown in FIG. 7 is initialized at step S13. In step S14, passage information of the entrance gate 20a (ID information of the entrance gate 20a, passage time information, etc.) is acquired via the wireless communication unit 32, and these are stored in the “time” and “event” columns of the history table 81. Record. In step S 15, the remaining fuel amount at the time of passing through the entrance gate is acquired from the vehicle 10 via the analog interface 37 and recorded in the “fuel remaining amount” column of the history table 81. In step S16, a measurement timer for periodically acquiring the remaining amount of fuel thereafter is started, and the process returns to step S11.

  If it is determined in step S12 that the gate is not the entrance gate 20a, it is determined in step S21 whether it is the exit gate 20b. If it is not the exit gate 20b, the process returns to step S11. In the case of the exit gate 20b, the measurement timer is stopped in step S22, and the measurement of the remaining fuel amount thereafter is stopped. In step S23, passage information (exit gate 20b ID information, passage time information, etc.) of the exit gate 20b is obtained via the wireless communication unit 32, and these are stored in the “time” and “event” columns of the history table 81. Record. In step S24, the remaining fuel amount at the time of passing through the exit gate is acquired from the vehicle 10 and recorded in the “fuel remaining amount” column of the history table 81. In step S25, the basic information of the passing vehicle 10 is read from the ETC vehicle-mounted device 30 and transmitted to the roadside device 21b via the wireless communication unit 32. In step S26, the history information of the travel history table 81 is transmitted to the roadside device 21b via the wireless communication unit 32.

  Note that the passage information of the entrance gate 20a (ID information of the entrance gate 20a, information of the passage time) is normally held by the ETC on-board device 30, and therefore the ETC card 40 in this case has only the fuel remaining amount at the time of passage through the entrance. May be recorded. In actual operation, there are cases where the ETC card 40 is extracted from the ETC on-board unit 30 and charged at a general exit toll gate as well as wirelessly traveling in the ETC lane. For this reason, if the ETC card 40 has received the passage information of another entrance gate again while holding the passage information of the entrance gate, the travel history table 81 is initialized in step S13, and the entrance passage information is again displayed. Start writing from.

  FIG. 6 is a flowchart of the travel history collection process according to the embodiment. When the measurement timer times out every time, the CPU 33 interrupts the process. In step S31, the “time” column of the travel history TB81 is updated at a predetermined time interval (for example, 5 minutes) when the timer times out. In step S32, the current fuel remaining amount is acquired from the vehicle 10 and recorded in the travel history TB81. In step S33, it is determined whether or not the current fuel remaining amount is significantly larger than the previous fuel remaining amount. If so, a fueling event is recorded in the “event” column of the history TB 81 in step S34. If the determination in step S33 is NO, it is further determined in step S35 whether or not the current fuel remaining amount is significantly smaller than the previous fuel remaining amount. Record the deoiling event in the column. If the determination in step S35 is NO, it is further determined in step S37 whether or not the current fuel remaining amount is substantially equal to the previous fuel remaining amount. If equal, in step S38, the "event" column is entered. Record parking (or stopping) events. If the determination in step S37 is NO, in step S39, whether the current fuel remaining amount is smaller than the previous fuel remaining amount, but is greater than the value obtained by subtracting the predetermined amount α from the previous fuel remaining amount. In the case of TES, an idling stop event is recorded in the “event” column in step S40. If the determination in step S39 is NO, in step S41, the current fuel remaining amount is smaller than the previous fuel remaining amount minus the predetermined amount α, but the previous fuel remaining amount is less than the predetermined amount. It is determined whether or not it is larger than the value obtained by subtracting β (> α). If YES, a running event is recorded in the “event” column in step S42. As described above, it is possible to distinguish between the actual fuel consumption associated with traveling and the fuel consumption due to other reasons, and thus it is possible to more accurately analyze the traveling performance (fuel consumption) in consideration of the environment of the section.

  FIG. 7 shows a travel history table 81 according to the embodiment. As time progresses, the remaining fuel amount [l] collected by the travel history collection process of FIG. 6 and the event determined based on the analysis are recorded. The “fuel consumption” column per predetermined time may not actually be recorded in the history table 81, but can be easily obtained by subtracting the current fuel remaining amount from the previous fuel remaining amount. By analyzing the transition of the remaining amount of fuel per predetermined time, the total fuel consumption related to the driving event can be extracted effectively, and the fuel efficiency faithful to the actual driving can be obtained.

  By the way, if the traveling performance of the vehicle 10 is judged only by the fuel consumption per predetermined time, it can be estimated that the vehicle 10 is traveling. However, even if the fuel consumption is the same, the vehicle 10 is traveling at high speed on the flat ground. It is not possible to distinguish whether it is driving on the second or third due to mountain roads or traffic jams. Therefore, in the second embodiment, information on the speed (km / h) is further acquired from the vehicle 10 and used for event determination.

  For example, when the speed is “0” km / h and the fuel consumption per predetermined time is “0” liter, it can be determined that the vehicle is parked (or stopped). On the other hand, even when the speed is “0” km / h, when the fuel consumption per predetermined time is “0.1” liter (that is, it is small but not “0”), it can be determined that the vehicle is idling. . Even when the vehicle is idling, if heating and cooling are involved, the fuel consumption of the section is deteriorated. This cannot be ignored. Further, the act of refueling or deoiling is also performed when the speed is “0” km / h. In addition, although it does not need to provide the column of "travel distance" km of a figure, it can obtain easily by integrating the travel distance per predetermined time (= predetermined time x speed).

  In the example of FIG. 7, the predetermined time is 5 minutes, but other predetermined time can be arbitrarily set. The shorter the predetermined time, the more accurately the travel history can be analyzed, but a lot of flash memory 42 is used. For example, when traveling on a relatively short section such as Tokyo Metropolitan Expressway, the predetermined time may be set relatively short, and when traveling on a relatively long section such as Tomei Expressway, the predetermined time may be set relatively long. .

  Moreover, although the example of FIG. 7 showed the case where each fuel residual amount acquired at the intermediate | middle time of the travel area was recorded, it is not restricted to this. In the process of step S16 in FIG. 5, if the measurement timer is not started, the remaining amount of fuel is not periodically acquired. For this reason, the history table 81 stores the entry gate passage time and the exit gate passage time. Only the passage time, the gate entry / exit event, and the remaining fuel amount acquired at the passage time of each gate are recorded. Therefore, the travel history information can be stored with a small memory capacity. FIG. 8 shows a graph of the travel history shown in FIG. If such a travel history graph is displayed on the display unit 36 in real time, the driver's manners can be effectively supported.

FIG. 9 is a flowchart of the toll fee charging process according to the first embodiment, and shows a case in which the toll fee is determined based on each gate entry / exit information. This process is executed at the accounting processing center 25. In step S51, the toll table 82 shown in FIG. 11 is referred to with each gate entry / exit information to obtain the standard toll and distance between the two ICs. In step S52, the fuel consumption amount of the section (= the remaining fuel amount at the inlet−the remaining fuel amount at the outlet) is obtained based on the information of each remaining fuel amount when passing through the entrance / exit gate. In step S53, the fuel consumption of the section is
Section fuel consumption = (section distance) / (section fuel consumption)
Ask for. That is, the average number of kilometers traveled per liter of fuel is obtained. In step S54, the travel performance (fuel consumption) in the section is ranked by referring to the rank table 83 of FIG. In step S55, a discount rate is determined according to the determined rank, and in step S56, a standard toll is discounted according to the determined discount rate. Alternatively, the reduced amount of the toll may be determined according to the rank and subtracted from the standard toll.

FIG. 10 is a flowchart of the toll fee charging process according to the second embodiment. By using information on the remaining amount of fuel periodically acquired between the gates at the entrance and exit, a charging process that is more faithful to the running record is performed. Shows the case. In addition, the same step number is attached | subjected to the process same as FIG. 9, or an equivalent. In step S51, the toll table 82 shown in FIG. 11 is referred to with each gate entry / exit information to obtain the standard toll and distance between the two ICs. In step S62, the total travel fuel consumption used in the travel event of the section is obtained with reference to the travel history table 81 of FIG. This travel fuel consumption amount can be easily obtained by summing up the fuel consumption amounts in the travel event column. This travel fuel consumption does not include an increase due to refueling, a decrease due to deoiling, or even a break due to idling stop, so a fuel consumption more faithful to actual driving performance can be obtained. In step S63, the travel fuel consumption of the section is
Section fuel consumption = (distance distance) / (distance travel fuel consumption)
Ask for. That is, the average number of kilometers traveled per liter of fuel is obtained. In step S64, the travel performance (fuel consumption) in the section is ranked by referring to the rank table 83 of FIG. In step S55, a discount rate is determined according to the determined rank, and in step S56, a standard charge is discounted according to the determined discount rate. Alternatively, a reduction in the toll is determined according to the rank, and is subtracted from the standard toll. In the second embodiment, since the fuel consumption can be obtained in accordance with the actual running amount, the rank classification (that is, the charge discount) that is faithful only to the actual running can be performed regardless of the presence or absence of refueling on the way. Yes.

  FIG. 11 shows an example of the charge table 82. Although the figure shows an example of application to a regular vehicle at Tomei Expressway, a similar charge table is provided for large vehicles and light vehicles, and it can be applied in the same manner as a regular vehicle. In the first column of this table 82, interchange names (however, only the main ones are shown) are arranged in order. For example, the charge from Tokyo to Yokohama is 750 yen, the distance is 19.7 km, The required time can be read as 14 minutes. The fare from Tokyo to Shizuoka is 4300 yen, the distance is 161.8 km, and the required time is 1 hour 53 minutes. In addition, the third column of this table 82 shows tolls to other ICs starting from Yokohama IC, and the fourth column is tolls to other ICs starting from Gotemba IC. The price is shown. The distance and required time in these cases can be easily obtained by simple subtraction.

  FIG. 12 shows a fuel efficiency rank table 83. Assuming that the fuel efficiency is expressed by how many kilometers per liter of fuel, it is ranked as 1, 2, 3, etc. in order of good fuel efficiency (long distance). For example, for a gasoline vehicle using gasoline as fuel, the range of fuel efficiency a to b (km) is ranked as rank 1, and the range of b to c that is shorter than this is ranked as rank 2. On the other hand, when the fuel (vehicle type) is different, the standard of fuel efficiency and the degree of influence on the environment are different. For example, for a diesel vehicle using light oil as fuel, the range of fuel efficiency a 'to b' (km) is ranked as rank 1, and the range of b 'to c' where the distance is shorter than this is ranked as rank 2. Although not shown, other fuel cell vehicles, biofuel vehicles, etc. can be ranked according to the same concept. In this way, the vehicle types that originally have good fuel economy are given preferential treatment on a separate scale, and in this table, vehicles that have performed relatively well among those vehicle type groups can be preferentially finely given.

  That is, if such a rank table 83 is used, a vehicle having any fuel that is relatively good in the same fuel group is given a high rank, and a vehicle that has poor fuel efficiency, regardless of which fuel is used. The quantity is given a low rank. That is, even a vehicle that is normally classified as rank 3 can be ranked as rank 2 if it travels corresponding to rank 2. This can encourage driving with good fuel economy. Similarly, the standard fuel consumption estimated from the basic information of the vehicle may be compared with the fuel consumption by actual driving, and the toll may be determined according to the degree of deviation from the standard. Of course, a high rank can always be given by purchasing a vehicle with good fuel efficiency (low-efficiency vehicle or low-pollution vehicle certified by a government agency or the like).

  As described above, according to the present embodiment, since the toll of the vehicle is discounted according to the good driving fuel consumption, the transfer to the environmentally-friendly vehicle type is promoted, the load of the cargo vehicle etc. is reduced, and the environment is considered. It is possible to promote vehicle driving, selection of a route without waste, and the like.

  The present invention can also be provided for a prepaid ETC card. In this case, the toll is directly deducted from the ETC card when passing through the exit gate 20b.
