BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a method for calculating a reduction amount of harmful substances in vehicle exhaust gas according to an embodiment of the present invention,
The calculation system, the trading method of emission rights of harmful substances, and the computer program will be described in detail with reference to the drawings.

First, when a user wants to receive a service for calculating the reduction amount of harmful substances in exhaust gas due to traveling of a vehicle, he / she registers as a member of a calculation service provider and receives a registration number. This membership registration is a vehicle related to the vehicle owned by the user, accessing the homepage owned by the calculation service provider from the computer owned by the user, along with the minimum personal information such as the user's name and email address. Do this by entering data. When the membership registration is completed, the computer of the calculation service provider notifies the computer of the user of the registration number. As the vehicle data, for example, the vehicle type of the vehicle owned by the user, the displacement of the vehicle, the type of fuel normally used, the component data in the exhaust gas, the maintenance history of the vehicle, the engine speed during normal traveling, the accelerator, etc. The operation status of the accelerator and the brake, such as the opening degree of the vehicle, are included. The computer of the calculation service company stores the vehicle data in the database in association with the registration number which is an identification symbol. These data are updated regularly as needed.

Next, when the user who is traveling the vehicle wants to receive a service for calculating the reduction amount of harmful substances, the first point, which is the current position of the vehicle, the second point, which is the target position to which the vehicle is heading, and A registration number, which is an identification symbol assigned to each vehicle of the user, is transmitted from the vehicle-mounted terminal to the computer of the calculation service provider. Further, the in-vehicle terminal has a function of receiving road / traffic information and notifying the position information of the vehicle to the detection device of the calculation service company, and also selecting an appropriate route from the current position of the vehicle to the destination position. The route is displayed. This suitable route is, for example,
The route with the shortest travel distance or the route with the shortest travel time. Here, normally, the route with the shortest travel distance and the route with the shortest travel time match, but when traveling in a congested area, it is better to make a roundabout and increase the travel distance. Due to the shorter length, the two routes may not match. The appropriate route displayed on the in-vehicle terminal is
The information is transmitted from the computer of the calculation service provider to the in-vehicle terminal, and the user drives the vehicle from the first point to the second point along the appropriate route. Specifically, as shown in FIG. 1, when the vehicle travels from the first point A to the second point G, an appropriate route displayed on the in-vehicle terminal is A.
In the case of → B → E → G, the user must select A → B → E → G
Drive the vehicle along the route.

After that, the computer of the calculation service company divides the appropriate route from the first point to the second point into a plurality of sections, and obtains the exhaust gas emission amount for each of these sections. This section is an interval divided for each position information of the vehicle sent from the vehicle-mounted terminal at a predetermined time or at a predetermined distance. Specifically, as shown in FIGS. 2 and 3, the vehicle position data and the predetermined reference points (A, B, etc.) that are periodically transmitted from the vehicle-mounted terminal every 2 to 10 minutes are calculated by the computer of the calculation service provider. The data is recorded in the movement route recording device via the detection device. When the vehicle state information is transmitted together with the vehicle position data, the vehicle state information together with the vehicle position data is recorded in the movement route recording device via the detection device. As shown in FIG. 3, the vehicle position data is data such as a section distance, a traveling time, an average vehicle speed, and an accelerator opening degree for each section. For example, in FIG. 2, when the vehicle is located at point S1, the latitude is 3 as shown in FIG.
The vehicle is located at 5 ° 21'31 "and the longitude is 139 ° 36'34", and the average speed when passing through point S1 is 20.
In km / h, the accelerator opening is 65%. The time when the vehicle passed the reference point A was 13: 2. further,
Passing time of A1 point is 13:05, A2 point is 13:10, B point is 13:13, B1 point is 13:15.
It was a minute.

Further, the exhaust gas emission amount is obtained by calculating the emission amount for each section based on the movement record shown in FIG. 3 and summing it. The emission amount for each section can be obtained by a function f having parameters such as traveling speed, travel time, vehicle type, fuel type, and accelerator opening degree, as shown below. Emission amount = f (section distance, running time, running speed, vehicle type, fuel type, accelerator opening degree, etc.) If there are unknown data items among the parameters, calculate using a predetermined standard value. . Further, it is also possible to obtain a standard value by inserting known parameters into the calculation function for each vehicle type, calculating all for each vehicle type, and multiplying the registered number ratio of vehicles for each vehicle type as a coefficient. In this case, the standard value can be calculated in advance by the function of emission amount = f (moving distance, moving time) based on the ratio of standard vehicles nationwide.

Then, the computer of the calculation service provider predicts an average travel route of the routes from the first point to the second point when the vehicle travels without receiving route guidance.
This average travel route should be the route that has the highest traffic volume from past traffic data and the route that considers the traffic ratio based on the probability that the user will select if the user does not receive route guidance. You can As shown in the vehicle traffic record of FIG. 4, at 13:00, A → C → G.
Since 60% of the vehicles pass through the route, the route with the most traffic is route A → C → G.
Is the average travel route. For the same reason, 1
Also at 3:20 and 13:40, the route A → C → G is set as the average movement route.

Further, when the average travel route is taken into consideration in consideration of the traffic ratio of the routes, the calculation is made based on the ratio of the routes selected by general traffic vehicles. For example, when traveling from a point A to a point G, the trend of a general passing vehicle at the relevant time is, as shown in FIG. 5, A → C → G is 58%, A → B →
When E → G is 21% and A → B → D → F → G is 7%, the average travel route is set in consideration of the ratio for each route.

After that, the amount of exhaust gas discharged when traveling on the average travel route is calculated. This amount of discharge is the amount of discharge =
It is calculated using a standard value calculation formula called f (moving distance, moving time). Specifically, when the route with the most traffic is set as the average travel route, the exhaust gas emission amount when passing through the route A → C → G is f (10 km, 44 minutes).
Further, the emission amount when the average travel route is taken into consideration in consideration of the passage ratio of the route is f (12 km, 51 minutes) × 0.21 + f
(10 km, 44 minutes) x 0.58 + f (15 km, 40
Min) × 0.07 + ...
In addition, the vehicle whose departure point and destination are the same as the relevant vehicle,
It is difficult to apply the above method to the whole process because many vehicles do not always travel at the same time, but if you divide by the main points in the route and consider each section, there are many vehicles traveling in the same section. Exists. Therefore, it is possible to obtain a comprehensive evaluation by appropriately dividing all traveling sections and applying the above method to obtain the total sum for each section.

Further, in the calculation means of the reduction effect of the calculation service company, the exhaust gas emission amount when the vehicle travels on the appropriate route which has been obtained so far and the exhaust gas when the vehicle travels without receiving the route guidance. Find the difference from the gas emission. Then, the reduction amount of the harmful substances in the vehicle exhaust gas can be calculated by multiplying the difference in the emission amount by the ratio of the amount of the harmful substances contained in the exhaust gas. The data of this reduction amount may be notified to the in-vehicle terminal when the vehicle reaches the destination. However, for example, it may be aggregated in units of one month and notified to the user or the corporation to which the user belongs. May be.

The method of calculating the reduction amount of harmful substances in vehicle exhaust gas has been described above, but a calculation system for performing these will be described below. The calculation system 1 according to the present invention, as shown in FIG.
Combined with the traffic information analysis / provision means 3, it forms a system. And analysis of road / traffic information
The providing means 3 includes a road / traffic situation detection device 5, a road / traffic situation analysis / prediction system 7, and a road / traffic information provision device 9.
The prediction system 7 is connected to the weather forecast information 11, the event information database 13, and the road traffic condition history database 15, and is configured to sequentially send these information to the road / traffic condition analysis / prediction system 7. Has been done.

The above-mentioned road / traffic condition detecting device 5 is used for the condition of traffic congestion on the road, the average traveling speed of vehicles, and the condition of facilities attached to the road.
It is a device that collects (for example, a parking lot full state). As a method of collecting information on traffic congestion and average traveling speed, there is a method of attaching a sensor to a highly public vehicle such as a taxi, a bus, or a truck of a delivery company to grasp the actual road condition. In addition, V attached to car navigation of general vehicles
The optical beacon of the ICS device functions as a sensor attached to the vehicle, and the roadside equipment not only sends data,
You can track individual vehicles and track vehicle position, route and speed. Furthermore, the status of road-related facilities such as parking lots can be easily collected by installing a notification device or the like for notifying each facility of the status.

Further, the road / traffic situation analysis / prediction system 7 analyzes and forecasts information necessary for providing information and an average vehicle flow based on the data collected by the road / traffic situation detection device. Is. Examples of information necessary for providing information include the following. Congestion / congestion status information indicating the current congestion status of the road, congestion / congestion prediction information indicating the predicted value of the congestion status up to several hours ahead, traveling time prediction information indicating the average travel time of a predetermined section, and parking lot Parking information that indicates the location of the vehicle and information on whether the vehicle is full or empty. The forecast is performed by referring to weather forecast information, event holding information, past road condition history information, and the like. The collected data is saved as history information in the road traffic situation history database each time.

On the other hand, in order to grasp the average vehicle flow, the average travel time of the cars between the reference points is set with one main intersection (main station, department store, amusement park) as one node (reference point). Is recorded every predetermined time. At the same time, an average travel route when moving from one point to another is also obtained for each time. It is desirable to set the reference point every several kilometers in the suburbs and every intersection or hundreds of meters in the city. In this case,
And in FIG. 7, the frequency of the route selected by the vehicle moving from the point A to the point G is recorded. At night, A → B → E →
The route is G, but the commuting time is A → B → D → F →
The frequency of each route is recorded every predetermined time, such as the route of G, the route of A → C → G during the day. In addition, point A,
The point G does not have to be the starting point or the destination of the vehicle to be recorded, and may be a main point on the way of the moving route. The road / traffic information providing device 9 provides an on-vehicle terminal having a communication function with road / traffic information that changes from moment to moment. Further, instead of the in-vehicle terminal, a display panel installed on the roadside or radio broadcasting may be used.

By installing a predetermined in-vehicle terminal, the latest information can be obtained at any place within the communication range. In addition, some information such as traffic congestion prediction information and recommended route information may be provided for a fee as a membership system. On the other hand, in the harmful substance reduction amount calculation system 1, a vehicle position / state detection device 21, a movement route recording device 23, an exhaust gas emission amount calculation means 25, an average movement route / movement time estimation means 27, an average Exhaust gas emission amount calculation means 29 and reduction effect calculation means 31 by route guidance are provided.

The vehicle position / state detecting device 21 is a device for notifying the position information of the vehicle from an on-vehicle terminal which is a road / traffic information receiving device. Also, vehicle type (manufacturer, model), fuel type, accelerator and brake operation status, running speed,
By adding a function of simultaneously reporting one or more vehicle state information such as engine speed, exhaust gas component data, and maintenance history, the accuracy of this system can be improved. Data that does not change during traveling, such as vehicle type and maintenance history, can be obtained from another database by notifying the vehicle number, and the communication load can be reduced.

The calculation system 1 corresponds to the period from when the user starts the connection to the computer of the calculation company by the in-vehicle terminal having the position notification function until the connection, that is, the usage period of the system 1. While moving, the moving route of the vehicle is detected based on the position information sent from the vehicle. In addition, the user has the advantageous effect of being able to obtain the latest road / traffic information. However, it is not necessary for the user to be aware that the vehicle position is recorded in the recording device 23 of the calculation service company by using the calculation system, and the calculation system 1 side also shows how the target vehicle moves. It is important to know the personal information of the driver or user who owns the vehicle. The movement route recording device 23 is a device that records the information sent from the vehicle position / state detection device for each vehicle at predetermined intervals. If vehicle status information is notified at the same time, record it as well. When a main point set by this system is passed, the passing point and its time are recorded as shown in FIG. The exhaust gas emission amount calculation means estimates the exhaust gas emission amount for each reference point section based on the movement record.

The calculation is obtained by a function having parameters such as traveling speed, traveling time, vehicle type, fuel used, and accelerator opening as shown below. this function is,
It can be identified by measuring each vehicle type in advance. Emission amount = f (section distance, travel time, traveling speed, vehicle type,
Fuel, accelerator opening, etc.) If there are unknown data items among the parameters, use the prescribed standard values. Further, it is also possible to obtain a standard value by inserting known parameters into the calculation function for each vehicle type, calculating all for each vehicle type, and multiplying by the ratio of the number of registered vehicles for each vehicle type as a coefficient. Then, in advance, based on the ratio of standard cars nationwide, the emission amount = f (moving distance, moving time)
The standard value can be calculated by the formula. The average travel route / travel time estimation means 27 predicts a travel route when the vehicle travels without receiving route guidance and sets it as an average travel route. As described above, this estimation method is a weighted average according to the route with the highest traffic volume and the probability of the user selecting.

The means 29 for calculating the average exhaust gas emission amount is, as described above, calculated by using the emission amount = f (moving distance, moving time), which is a standard value calculation formula. The means for calculating the reduction effect by the route guidance performs the route guidance by calculating the difference between the emission amount obtained by the exhaust gas emission amount calculation means and the emission amount obtained by the average exhaust gas emission amount calculation means. The reduction amount of exhaust gas when the vehicle receives the vehicle is calculated.

It should be noted that the present invention is not limited to the above-described embodiments, and various changes and modifications can be made based on the technical idea of the present invention. For example, by mounting a sensor for measuring the exhaust gas component on the vehicle and detecting the exhaust gas component at every predetermined time, it is possible to quantify the exhaust gas component actually discharged during traveling of the vehicle. In addition, the service provider does not provide the exhaust gas calculation service itself by operating the optimal route guidance service for automobiles with the profit obtained by transferring the emission rights of harmful substances obtained by reducing exhaust gas. Moreover, the optimum route guidance service can be provided to the user free of charge or at low cost.
