Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an environmental load reduction system.
[0002]
[Prior art]
In recent years, global environmental problems have increased, and exhaust gas emitted from vehicles such as automobiles has been apt to be more strictly regulated. NO _X CO, THC (Total Hydro Carbon), and soot (dust) and other harmful substances in exhaust gas (represented as environmentally hazardous substances in this specification) to reduce the burden on the global environment (environmental burden) Reducing their emissions is being considered. Along with this, a vehicle manufacturer has developed a vehicle with a reduced amount of environmental load, and has achieved some results.
[0003]
In addition, attention has been given to vehicle operators (crew members) in an effort to reduce the environmental burden, and conscientious crew members in response to this will encourage idling stop and start suddenly. Avoid sudden braking. In addition, in connection with this, the operator of the vehicle provides an operation management system for managing the operation of each crew member, so that the operation details of each crew member can be recorded, and driving with high safety and economy can be performed. Guidance to keep in mind.
[0004]
On the other hand, local governments in various regions are also considering setting an upper limit of the amount of environmentally hazardous substances that can be released within a given area and regulating it.
[0005]
It has been studied to calculate the amount of environmentally hazardous substances discharged by calculation as shown in the following formula (1) based on the type of vehicle and the distance traveled within a predetermined area.
Emissions of environmentally hazardous substances ≒ K x mileage ... Formula (1)
However, K is a coefficient determined by the specification of the vehicle, and indicates the discharge amount of environmental load substances per unit travel distance when traveling according to a predetermined travel pattern.
[0006]
[Problems to be solved by the invention]
However, the conventional calculation method as described above has not been able to determine the exact amount of environmentally hazardous substances discharged by each vehicle. In other words, even if the crew is suddenly starting and braking suddenly even if the mileage is the same, or if idling is not stopped when stopping for a long time, if the vehicle is insufficiently maintained, A larger amount of environmentally hazardous substances was released than the amount calculated by equation (1). On the contrary, the environmental load substance released when traveling on the expressway at a substantially constant speed is much smaller than the amount calculated by the equation (1).
[0007]
In other words, in the conventional calculation method as shown in the equation (1), the amount of release of environmental load substances is calculated only by the vehicle type, year and mileage regardless of the vehicle maintenance and driving conditions. However, it was only possible to calculate a value far from the actual environmental load situation, and it was not suitable for the actual situation. In addition, it is troublesome to add up the distance traveled in a predetermined area, and there is a possibility that the regulation has no meaning if a false report is made.
[0008]
On the other hand, in the current operation management system, the management items of the vehicle operators are mainly maintenance for vehicles and maintenance due to breakdowns, and for crews, safe driving and efficiency improvement of delivery. Since the release amount of the substance is unknown, it was not possible to promote the improvement of the driving ability effective in reducing the environmentally hazardous substance.
[0009]
In addition, it is not practical to install an expensive gas analyzer that can measure a plurality of environmentally hazardous substances in a vehicle just to measure the amount of environmentally hazardous substances released. In addition, since a gas analyzer that performs multi-component analysis cannot perform real-time measurement, even if it is mounted on a vehicle, it has not been possible to find a relationship with the driving situation.
[0010]
The present invention has been made in consideration of the above-mentioned matters, and is a vehicle operation management system that acquires time, speed, and distance data to improve driving safety and operation efficiency. It is a system for more effectively reducing the amount of environmental load together with operation management, and feeding back the measurement results to the vehicle and crew to ensure proper driving technology to reduce the environmental load. The objective is to provide an environmental load reduction system that encourages each crew member to learn and enables the setting or resetting of operation routes that take into account the reduction of emissions of environmentally hazardous substances.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides:
at least A rotational speed measurement unit that measures the engine rotational speed, a gas analyzer that measures the discharge concentration of environmentally hazardous substances in real time, car A position measurement unit that measures the current position of both, the emission concentration of environmentally hazardous substances discharged from the vehicle, at least the engine speed, Place A recording unit for recording operation management data together with , A wireless communication unit for transmitting the operation management data to the information processing device on the management center side In-vehicle device having

Has a function to instruct changes to directions Information processing device And a wireless communication unit that receives the operation management data from the in-vehicle device Management center with
An environmental load reduction system characterized by comprising:
[0012]
Among the above components, the engine rotation speed measurement unit and the vehicle position measurement unit are recorded as operation management data in the recording unit of the current operation management on-vehicle device.
Therefore, even though the current operation management in-vehicle device is equipped with a gas analyzer and a temperature measurement unit, and the configuration for recording the discharge concentration and temperature of environmentally hazardous substances measured as these as operation management data is extremely simple, The information processing apparatus can accurately calculate the discharge amount of the environmental load from the vehicle using the engine speed, the temperature, and the discharge concentration of the environmental load substance. In addition, since the operation management data also records position information, the information processing apparatus can analyze how much environmental load the vehicle discharges in which region (discharge distribution).
[0013]
In addition, it is possible to appropriately manage the vehicle and the crew using the environmental load emission distribution analyzed by the information processing apparatus, and as a result, it is possible to reduce the environmental load of the vehicle. A crew member can recognize which operation of his / her driving contributes to the reduction of the environmental load and which operation increases the environmental load, which can be used to improve driving skills. The manager can reduce the fuel consumption and achieve an economic effect by operating the driver with less environmental load, and can avoid the concentration of environmental load and avoid litigation problems related to air pollution.
[0014]
The in-vehicle device is Above A warning operator that issues a warning to the crew when the environmental load exceeds a preset standard value Step In this case, each crew member can know in real time the operation that increases the environmental load by his / her driving method, which can be used to improve driving skills.
[0015]
The in-vehicle device has a wireless communication unit that transmits operation management data to the information processing device on the management center side, and the management center has a wireless communication unit that receives operation management data from the in-vehicle device. Because The operation of each crew member increasing the environmental load can be monitored by the management center.
[0016]
The information processing apparatus is each Discharged from the vehicle Said Monitors the environmental impact and has a function to instruct a vehicle whose environmental impact is greater than the reference value to change to a route with a lower environmental impact. Because In addition, it is possible to eliminate an increase in the environmental load due to road congestion, avoiding the increase in the environmental load from being concentrated on one section, and shortening the delivery time.
[0017]
The reference value of the environmental load is determined in units of sections divided for each traveling direction between the intersections. Because In addition, it is possible to reliably grasp the congestion state of the road, and to accurately know a more efficient delivery route (delivery order).
[0018]
When the information processing apparatus has a function of instructing a route with a low environmental load from the relationship between the weight of the load and the delivery distance, a delivery route is set so that the heavy load is loaded as soon as possible and delivered first. Can effectively reduce the environmental load.
[0019]
The information processing device is connected to each vehicle. Asking for Based on the environmental load, depending on the driving conditions in the section Above If you have a database that sets or corrects the environmental load reference value, you can refer to this database to accurately determine the running state of each section, and deliver efficiently and efficiently with delivery operations. A route can be set.
[0020]
When the database aggregates the reference value of the environmental load for each section for each operation time zone, and the information processing apparatus has a function of instructing a route with a low environmental load taking the delivery time zone into consideration In this case, the delivery order can be set so as to aim at a time zone with relatively little congestion, so that a more effective delivery time zone can be set, and both environmental load reduction and efficient delivery can be achieved.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an overall view showing an example of the configuration of an environmental load reduction system 1 according to the present invention. In FIG. 1, 2 is a vehicle for carrying out transportation work, and 3 has a plurality of vehicles 2, for example, to carry out the transportation business. A management center managed by an operating carrier (business operator), 4 is an information processing device (hereinafter referred to as an operation management server) for performing operation management by each vehicle 2, and 5 is an in-vehicle device mounted on each vehicle 2. is there. In this example, the in-vehicle device 5 acquires and records the function as the operation management meter, that is, data of time, speed, and distance. In the following description, the in-vehicle device is described as the operation management in-vehicle device 5.
[0022]
The operation management server 4 and the operation management in-vehicle device 5 constitute an operation management system 6. That is, in the case of this example, by installing the operation management vehicle-mounted device 5 by incorporating it in the operation management system 6, an operator who has already adopted the operation management system 6 can easily introduce the environmental load reduction system 1. ing. Reference numerals 3a and 3b denote antennas of wireless communication units (not shown) that communicate with the operation management vehicle-mounted device 5 of each vehicle 2 to transmit and receive the operation management data D.
[0023]
The operation management server 4 executes a management program P for enabling more efficient transportation by instructing and monitoring the operation management vehicle-mounted device 5 of each vehicle 2. The management program P aggregates the operation management data D accumulated by each operation management device 5 and creates various databases DB. In particular, in the present invention, the reference value is accumulated as the database DB from the magnitude of the environmental load of each part in the jurisdiction.
[0024]
The reference value of this environmental load is initially set to be uniform, for example, and is corrected as the actual condition of the running state such as the degree of congestion and the inclination angle as the practice is repeated. It is also possible. Further, it is possible to install a reference value taking into consideration the actual situation to some extent from the beginning. Further, the management program P monitors the discharge amount of the environmental load, and makes it possible to set a vehicle dispatch route using the database DB so as to disperse the environmental load as much as possible.
[0025]
Further, the present invention does not limit the number of management servers 4 or the number of management centers 3. That is, although not shown, the management server 4 and the management center 3 of this example provide, for example, an information processing device (such as a personal computer) for acquiring the operation management data D as a part of the management server 4 at each business office. Thus, it is possible to prevent the processing from being concentrated on one management center 3 side. Further, it goes without saying that the management center 3 may be provided for each business office owned by the business operator, or conversely, the management center 3 that is not caught by the business operator's framework may be formed.
[0026]
On the other hand, the operation management vehicle-mounted device 5 shown in this example includes, for example, a handy terminal 7 for inputting work contents by a crew member, and a sensor box 8 connected to the handy terminal 7 for inputting various measurement results regarding the vehicle 2. , A recording unit 9 for recording various measurement results input via the sensor box 8, and the current position of the vehicle 2 as an artificial satellite S ₁ GPS (Groval Positioning System) measuring by communication with a position measuring unit 10 such as a receiver, a wireless communication unit 11 for communicating with the operation management server 4 of the management center 3, and the position measuring unit 10 connected to each And a car navigation system 12 that provides guidance such as directions to be delivered by the crew.
[0027]
In this example, although the example which uses the GPS receiver 10 as a position measurement part is disclosed, this does not limit this invention. That is, various configurations such as a gyro sensor, a position measuring unit using geomagnetism, and combinations thereof are conceivable.
[0028]
In addition to the GPS receiver 10, the sensor box 8 includes a temperature measurement unit 13 that measures the temperature of air that is taken into the diesel engine 2 a of the vehicle 2, and a rotation speed measurement unit 14 that detects the rotation speed of the diesel engine 2 a. And NO contained in the exhaust gas discharged to the outside through the exhaust pipe 2b _X A gas analyzer 15 for detecting the concentration of the gas is connected. In addition, although the rotation speed measurement part 14 of this example shows the example of the connection part which takes out the signal which shows engine rotation speed from the vehicle-mounted computer 2c, this invention does not limit this structure.
[0029]
The recording unit 9 includes a memory card 9a for recording operation management data D measured by the operation management vehicle-mounted device 5, and a card reader 9b of the memory card 9a. 3 and set in the card reader 9b. Then, when the vehicle 2 returns, the operation management data D for one day (after a series of collection and distribution operations) is sucked into the management center 3 by the memory card 9a.
[0030]
The data recorded as the operation management data D includes, for example, the current position L measured by the GPS receiver 10, the temperature T measured by the temperature measurement unit 13, and the rotation speed measurement unit 14. Engine speed R and NO measured by the gas analyzer 15 _X Is recorded together with other travel information such as the vehicle speed of the vehicle 2.
[0031]
Although not shown in FIG. 1, the operation management vehicle-mounted device 5 analyzes the measurement result input via the sensor box 8 and calculates the change over time of the environmental load discharged during traveling. For example, in the handy terminal 7.
However, this does not particularly limit which part of the in-vehicle device the arithmetic processing unit is provided. By the way, the calculation by the calculation processing unit is performed as shown in the following equation (2), for example.
Environmental load = C × R × 273 ÷ T × K (2)
Where C is NO _X The gas concentration, R is the engine speed, T is the absolute temperature, and K is a constant specific to the engine 2a that varies depending on the engine displacement.
[0032]
That is, in the case of the diesel engine 2a used as a power source of the transportation vehicle 2, the amount of exhaust gas discharged when the engine makes one revolution is more accurately determined by the temperature T of the air when the air is taken in and the exhaust amount. Can be sought. Therefore, engine speed R and NO _X By multiplying this by the gas concentration, the environmental impact (NO _X The instantaneous value of the gas emission amount can be calculated in real time.
[0033]
Note that the air temperature T is measured in order to perform an operation taking into account the difference in exhaust gas emissions caused by the expansion due to the temperature, but it can be omitted if a high degree of accuracy is not required. is there. On the contrary, when a supercharger is mounted on the engine 2a, it is necessary to attach a pressure sensor for measuring the boost pressure and multiply the formula (2) by this boost pressure.
[0034]
In the case of the diesel engine 2a, NO _X If the concentration measurement can be performed, other environmental load components, that is, CO ₂ The amount of discharge of soot (dust) and the like can also be obtained approximately, but it goes without saying that an analyzer capable of performing these concentration analyzes in real time may be attached to the operation management vehicle-mounted device 5. However, NO _X The gas analyzer 15 for detecting the concentration of the gas can be analyzed in real time simply by attaching the sensor unit 15a to the exhaust pipe 2a, so that the configuration can be simplified.
[0035]
The arithmetic processing unit monitors the change over time in the amount of discharge of the environmental load obtained by performing the calculation, and records the change over time in the amount of discharge of the environmental load as operation management data D in the memory card 9a. On the other hand, when the delivery route is determined, the memory card 9a is transferred from the operation management server 4 with a reference value of the environmental load discharge allowance in each section on the delivery route.
[0036]
Therefore, the operation management vehicle-mounted device 5 of this example is the environmental load (NO in this example) obtained by the above calculation. _X ) Is integrated for each section, and this is compared with the standard value of environmental load. When the environmental load discharged from the measured value exceeds the standard value, the environmental load discharged during driving An alarm or voice warning can be issued via the warning means 7a such as a speaker that the size of is larger than the reference. This allows crew members to know their driving method and which part of the kite is increasing the environmental load, and can improve their driving skills as seen from the cross section of the environmental load.
[0037]
In addition, although the example which recorded the reference value of discharge | emission allowable amount of environmental load for every area in the recording part 9 is given in this example, this invention is not limited to this. In other words, when the standard value of the environmental load that is emitted when performing a series of operation management is set, and if the current operation is continued, it will clearly exceed this standard value, A warning may be issued via the warning means 7a.
[0038]
The wireless communication unit 11 includes, for example, a wireless device 11a that performs wireless communication with the management center 3 using ground waves, and an artificial satellite S. ₂ And a wireless device 11b that communicates with the management center 3 by satellite relay via. Further, in this example, a fax printer 11c that is connected to the wireless communication unit 11 and outputs an instruction from the management center 3 is provided. Although the wireless communication unit 11 includes the wireless device 11a that performs terrestrial communication, it is possible to perform communication with reduced running cost. However, the wireless communication unit 11 includes the wireless device 11b that performs communication using satellite relay. Is possible. However, the present invention is not limited to including both communication devices 11a and 11b.
[0039]
When the discharge amount of the environmental load exceeds the reference value of the environmental load, the operation management data D including the temporal change of the environmental load at that time is included in various travel information via the wireless communication unit 11 on the management center 3 side. You may forward to. With this configuration, the operation management server 4 of the management center 3 can monitor the magnitude of the environmental load caused by each vehicle 2.
[0040]
Note that the transfer of the operation management data D to the management center 3 is not limited to when the amount of environmental load discharged exceeds the environmental load reference value, but may be sequentially performed at each intersection or every predetermined time. It may be. In this case, the management center 3 side monitors the amount of environmental load discharged by each vehicle 2 using the transferred operation management data D, and when this exceeds a reference value, the management center 3 side transmits the wireless communication. By configuring so that a signal for issuing a warning to each crew member is transmitted using the unit 11, the warning means 7a on the vehicle 2 side can issue a warning by alarm or voice to the crew member.
[0041]
That is, the management center 3 side considers the state of the vehicle 2 in which the environmental load is increasing and the surrounding situation, or contacts the crew member using the wireless communication unit 11 to investigate the cause of the increase in the environmental load. can do. When the management center 3 analyzes the operation management data D and it becomes clear that the cause of the increase in environmental load is caused by the failure of the vehicle 2 or the engine deterioration, the maintenance of the vehicle 2 is performed as soon as possible. Can be performed.
[0042]
If the cause of the increase in the environmental load is due to the driving method of the crew, an instruction for changing the driving method can be given to the crew on the spot using the wireless communication unit 11 or the like, for example. On the other hand, if the increase in environmental load is due to congestion, in order to avoid further increase in environmental load, another route can be searched and this can be instructed to the crew on the spot. At this time, the reference value of the environmental load in each section on the new delivery route is transferred to the recording unit 9 using the wireless communication unit 11.
[0043]
The in-vehicle navigation system 12 includes map information and the like, and shows directions to the crew. In addition, the navigation system 12 of this example includes, for example, the wireless communication unit 11 in addition to road traffic information from a vehicle information communication system (VICS: trade name) or ATIS (Automated Transit Information System). In accordance with the instruction received from the management center 3 via the route, the delivery route is determined and the route is instructed to the crew to support efficient transportation. The information from the vehicle information communication system and ATIS is received by the management center 3, and the management center 3 side searches for the route taking into consideration the reduction of the environmental load and transfers it to the navigation system 12. It may be.
[0044]
When a series of work is completed using the environmental load reduction system 1 described above, the operation management data D accumulated in the environmental load reduction system 1 is transferred to the operation management server 4 via the memory card 9a when the vehicle 2 is received. It is transferred to a database DB for optimizing future delivery.
[0045]
FIG. 2 is a diagram showing a flow of processing by the environmental load reduction system 1. As illustrated in FIG. 2, when the crew member performs delivery using the operation management on-vehicle device 5, the operation management on-vehicle device 5 discharges at least from the vehicle 2. _X The information such as the concentration C and the intake air temperature T is measured as data for operation management together with the traveling information such as the current position L and the engine speed R. (Step St ₁ )
[0046]
Further, the measured values C, R, T, L, etc., which are measured are accumulated by being recorded in the recording unit 9 as operation management data D together with other travel information, and this operation management data D is stored when the vehicle 2 is stored. Is transferred to the operation management server 4 (step St ₂ ).
[0047]
In this example, the operation management data D is transferred mainly through the memory card 9a, so that the information collection in the management center 3 is accurately performed. However, the present invention limits this point. Instead, the operation management data D may be transferred sequentially using the wireless communication unit 11 exclusively. In this case, since it is not necessary to use a recording medium such as the memory card 9a, it is more useful, and each operating sales person can monitor the discharge amount of the environmental load from each vehicle 2 almost in real time.
[0048]
The crew members who have completed a series of operations, after the completion of transportation, record the amount of environmental load calculated by the operation management server 4 and other operation records such as time, speed and work data recorded as other original operation management data. Therefore, it is possible to make efforts to recognize driving habits in the driving method and reduce the environmental load. Further, at this time, although not shown in the figure, a comparison between the own driving record viewed from the cross section of the environmental load and the in-house average, the national average, or the past self-average may be performed.
[0049]
Next, the operation management server 4 uses the accumulated operation management data D to integrate all environmental loads discharged from the vehicle 2 in all sections through which the vehicle 2 passes, and for example, together with the operation time It is stored in the database DB so as to be left as a parameter in each section. (Step St _Three )
[0050]
Further, the environmental load emission parameters remaining in the database DB for each vehicle 2 are used to optimize the environmental load reference value in each section, and the environmental load reference value in each section is more realistic. It is adjusted to match. (Step St _Four ) In other words, by adjusting the reference value based on the actual environmental load data obtained from actual driving, the environmental load reference value is reduced on, for example, downhill roads and roads with relatively low congestion. On the road, each crew member can be instructed so as to reduce the environmental load without difficulty by slightly increasing the reference value of the environmental load.
[0051]
The reference value of the environmental load recorded in the database DB is preferably a section partitioned for each traveling direction between the intersections. That is, it is possible to divide the road to be traveled between the intersections to the minimum, and to set the reference value of the environmental load in accordance with the inclination by dividing the traveling direction.
[0052]
In addition, it is desirable that the reference value of the environmental load is totaled for each operation time zone.
In other words, even in the same place, the traffic volume varies depending on conditions such as morning and evening commuting hours, meals, and daytime, and it is possible to take into account fluctuations in environmental load that fluctuate due to this. . It is also desirable to distinguish between the date, day of the week, and weather in the concept of the operating time zone. In other words, the overall environmental load may increase or decrease due to Saturdays, Sundays, national holidays, the end of the month, the beginning of the month, collection deadlines (5, 10, 15, 20, 25), weather conditions, etc. It is possible to take into account the increase or decrease of.
[0053]
Next, the operation management server 4 makes a route plan for the next delivery according to the environmental load reference value recorded in the database DB, thereby making a delivery plan with a smaller environmental load (step St). _Five ). And step St ₁ Return to and carry out work according to the new delivery plan.
[0054]
As described above, by using the environmental load reduction system 1, as the database DB grows, an optimal course with a smaller environmental load is set, and the delivery order and time zone are taken into consideration. It is possible to make a plan. Furthermore, selecting a delivery route that reduces the environmental load results in selecting a delivery route that is less congested and consumes less fuel, so that an economic effect can be expected.
[0055]
FIG. 3 is a diagram showing an example of a delivery route plan when the environmental load reduction system 1 having the above-described configuration is used. In FIG. 3, P ₁ ~ P _Five Are delivery destinations that perform collection and delivery operations, respectively, and are assumed to be company S, company A, company B, company H, and company C, respectively. Now, S Company P ₁ From Company C P _Five 800kg, Company A P ₂ To H Company P _Four 10kg, Company B P _Three To H Company P _Four Consider a delivery route that transports 15 kg of luggage.
[0056]
In FIG. 3, C ₁₁ ~ C ₄₆ Indicates each intersection in the illustrated area, and these intersections C ₁₁ ~ C ₄₆ The allowable discharge amount of the environmental load that is divided and adjusted for each section is indicated by a rectangle arranged in each section. In addition, since each section is a section that is divided between the intersections for each traveling direction, the environmental load discharge allowance is shown in two sections depending on the traveling direction even between the same intersections.
[0057]
In the example shown in this example, the intersection C ₁₄ ~ C ₄₄ The traffic volume and the environmental load of the road passing through ₁₁ ~ C ₄₁ Through the road and intersection C ₁₁ ~ C ₁₅ , C ₃₁ ~ C ₃₅ It can be seen that there is a relatively large amount of traffic and environmental load on the road that passes through. Also, especially on roads that extend from north to south, there is an increase in environmental load in the north direction, ₁₂ ~ C ₄₂ To intersection C ₁₁ ~ C ₄₁ It turns out that it is an uphill when heading for, and the environmental load increases so much in the section in the upward direction.
[0058]
Here, if the delivery of the package is performed taking into consideration only the shortest distance, the vehicle 2 will first be made up of company S as shown by the solid arrow. ₁ After loading 800kg of luggage at intersection C ₄₅ , C ₄₄ , C ₃₄ , C _{twenty four} Drive in the order of Company A P ₂ Heading for 10 kg of luggage, _{twenty four} , C ₁₄ , C ₁₃ , C ₁₂ Drive in the order of B company P _Three Load 15kg luggage at intersection C ₁₂ , C ₁₁ , C _{twenty one} , C ₃₁ Traveling in the order of H company P _Four And unload the 10kg and 15kg packages, and finally at intersection C ₄₁ C company P through _Five The route to unload 800kg can be considered.
[0059]
The above-mentioned route has a lot of traffic and not only frequently uses roads where congestion occurs, but also keeps loading 800 kg of heavy loads from the beginning to the end, so it is inevitable that the environmental load will be discharged. In addition, since the vehicle travels back and forth many times on the roads with different heights, the environmental load associated with this may increase.
[0060]
On the other hand, in the route search taking into consideration the environmental load using the environmental load reduction system 1 of the present invention, roads with a high environmental load are avoided as much as possible, and the load weight of the load is taken into consideration, so the route is selected. Therefore, the delivery of the same package described above is a route indicated by a virtual line.
[0061]
First, S Company P ₁ After loading 800kg of luggage at intersection C ₄₅ , C ₃₅ , C ₃₄ , C ₃₃ , C ₄₃ , C ₄₂ Drive in the order of Company C P _Five At the intersection C ₄₂ , C ₃₂ , C _{twenty two} , C _{twenty three} , C _{twenty four} Drive in the order of Company A P ₂ 10kg load at the intersection C _{twenty four} , C _{twenty three} , C _{twenty two} Drive in the order of B company P _Three Load 15kg of luggage at the intersection C _{twenty two} , C ₃₂ , C ₃₁ Traveling in the order of H company P _Four The route to unload the 10kg and 15kg loads can be considered.
[0062]
As shown in this example, by searching for a route that takes the environmental load into consideration, it is possible to reduce the discharge amount of the environmental load even when the same package is transported. In addition, by selecting routes that take environmental load reduction into consideration, it is possible to select routes with less traffic volume, which in turn can reduce transportation time and fuel consumption, and more efficient route search. It can be performed.
[0063]
In addition, although description using drawing is abbreviate | omitted in this example, by using an expressway, acceleration / deceleration by a signal can be eliminated and an environmental load can be made small by that much. Therefore, it is desirable that weighting can be set for the relationship between the increase in transportation costs associated with the use of the expressway and the reduction amount of the environmental load in the selection of the delivery route by the environmental load reduction system 1. Further, it is desirable to use road width and safety of roads in each section, and additional information such as information that changes every moment, such as construction information, when determining the route.
[0064]
Further, as already described in detail with reference to FIG. 2, the allowable discharge amount of the environmental load is continuously corrected based on the operation management data D collected from each vehicle 2 so as to match the actual situation. As the environmental load reducing system 1 of the present invention is used for a long time, more efficient delivery is possible, and the environmental load can be gradually reduced.
[0065]
【The invention's effect】
As described above, according to the environmental load reduction system of the present invention, the crew member can confirm whether his / her driving method is good or bad in the environmental load section after the operation is completed, and can improve the next operation. It can be reflected in education. In addition, when issuing a warning due to environmental load in real time when the vehicle is driving, the crew can recognize the driving method that causes the environmental load to increase, and renew the driving method to have a driving method with less environmental load. You can turn it on.
[0066]
Further, from the obtained results, it is possible to construct a delivery plan with less environmental load by reflecting it in course setting, vehicle dispatch setting, delivery time setting, etc. for reducing the environmental load.
