Description

The present invention is equipped with an evaluation apparatus that is effective in displaying on the instrument panel so that the carbon dioxide emissions of automobiles can be recognized to prevent global warming, and that allows the driver to understand driving operations that reduce carbon dioxide emissions. An automobile carbon dioxide display device is provided.

Currently, global warming gas of carbon dioxide is a problem on a global scale. Due to global warming, there are concerns about changes in sea level rise due to the melting of weather, climate, and glaciers, and the spread of tropical infectious diseases caused by mosquitoes.

According to the Ministry of the Environment's report on greenhouse gas emissions, carbon dioxide (CO2) emissions are divided into energy sources and non-energy sources, and the energy sources are industrial sectors (factories, etc.) and transport sectors (automobiles, ships). Etc.), business and other sectors (commerce, services, establishments, etc.), household sector, energy conversion sector (power plant, etc.), the non-energy origin comes from industrial processes, waste (incineration, etc.), fuel These carbon dioxide emissions are subdivided into leaks, and according to the preliminary figures for 2005, carbon dioxide emissions have increased from the base year of the Kyoto Protocol except for the industrial sector and industrial processes. Reduction is in a state that cannot be physically implemented.

Therefore, in an automobile manufacturer, an engine car that is an internal combustion engine that operates with fossil fuels such as gasoline, light oil, and natural gas and a car that uses hydrogen fuel as fuel emit carbon dioxide. The engine can be an injector direct injection engine with good combustion efficiency, the hydraulic power steering can be changed to an electric power steering of an electric motor to reduce the load on the engine, or the transmission can be a continuously variable transmission with little loss. Tire manufacturers have also made efforts to improve fuel consumption per liter of fuel throughout the automobile industry by reducing tire rolling resistance.

In addition, the government has also been giving preferential treatment for changing cars as a green tax system for fuel-saving vehicles.

However, compared to 1990, which is the base year of the Kyoto Protocol, automobiles in recent years have achieved a significant improvement in fuel efficiency in terms of performance. Carbon dioxide emissions from the transport sector, which emits 20%, have not decreased, but have increased by about 20%.
Homepage of the Ministry of the Environment (Global Warming and International Environmental Cooperation / Global Warming Countermeasures / Japan Greenhouse Gas Emissions and Emission Factors / Japan Greenhouse Gas Emissions / Greenhouse Effect in Fiscal 2004) About the amount of gas emissions and the preliminary figures for greenhouse gas emissions in FY2005).

Currently, the driver (user) cannot recognize the fact that the driver's own vehicle emits carbon dioxide while driving the car. It is in a state where the amount of carbon dioxide emitted by the operation position of the shift operation cannot be grasped.

In such a state, the driving operation for reducing the emission amount of carbon dioxide, which is a warming gas, is not learned. And since it is difficult to judge how much carbon dioxide the driver emits, we cannot share the sense of crisis of global warming.

Also, in vehicles, carbon dioxide emissions, which are a cause of global warming gas, are not indexed and standardized as equipment so that the driver can recognize them.

Therefore, the driver of the car in the transportation sector can recognize the exact amount of carbon dioxide emission of the car that he / she is driving while driving, and the engine is wasted or stopped. The amount of greenhouse gas emitted to the earth by actions such as idling, sudden start, and rapid acceleration, and the damage is caused by the carbon dioxide emission display device, the driver can reduce the carbon dioxide emission Make it possible to visually recognize the amount of carbon dioxide emitted from a car at any time while driving so that you can acquire driving operations that can be reduced.

And it enables it to drive | operate on the basis of the discharge | emission amount of the carbon dioxide discharged | emitted from a motor vehicle as a reference | standard of driving | operation operation.

The driving operation is evaluated from the carbon dioxide emission. The more drivers that aim to get good reviews, the more carbon dioxide emissions can be reduced.

And, in the case of automobile inspection and scrapped cars, it is possible to record the exact total amount of carbon dioxide emissions of this car in a record book such as a maintenance notebook, etc. Data can be fed back to government agencies such as the Ministry of the Environment and the Ministry of Land, Infrastructure, Transport and Tourism, and automobile manufacturers.

By leaving data on emissions, government agencies can take various measures because they gather data that can be analyzed in detail, such as region, year, model name, total distance, and total carbon dioxide emissions. (For example, it can be grouped by year or car name model), and the automaker can develop a fuel-saving car with improved carbon dioxide emissions that is further improved.

Although the present invention has developed a technology for reducing carbon dioxide emissions developed by automobile manufacturers, there are drivers who have a wealth of knowledge about automobiles because there are various people of young and old, Some drivers do not have knowledge, and even if the technology to reduce carbon dioxide emissions is developed, those who have no knowledge of automobile technology are driving vehicles that emit a lot of carbon dioxide emissions. .

Therefore, even a driver who has no knowledge of automobiles can display his / her own carbon dioxide emission in the instrument panel, and the carbon dioxide emission display device that displays the state of short-term emissions and long-term emissions related to changes. Knowledge of the name and function of the equipment of the technology that can reduce the amount of carbon dioxide emissions during driving operation by making it possible to realize how much emissions are generated by driving and using the carbon dioxide emissions as an indicator of driving People who don't have the ability to understand naturally through driving experience.

Therefore, the instrument panel equipped with a car speedometer is equipped with a display device that displays information on carbon dioxide emissions for a short time and a long time, and is used as an indicator to prevent global warming, which has been developed by automobile manufacturers. Even if the technology for reducing carbon dioxide is not understood as knowledge, accelerator operation and shift operation can be naturally acquired by the driver's driving using the display of carbon dioxide emission as an index. The technology for preventing global warming developed by automobile manufacturers is understood and enjoyed by many drivers.

For example, in an engine brake of an automatic vehicle with a general specification, when the accelerator is turned off and the overdrive is turned off, the overdrive off indicator light is lit, the shift is lowered by one step, the engine brake is applied, and the engine shaft rotates. Although everyone can understand that the engine speed increases as the speed (tachometer) speed increases, the fuel cut-off function is actually activated so that no fuel is consumed. This is because the display of carbon dioxide emissions is indexed as an instrument in the instrument panel, so that the amount of carbon dioxide emissions can be reduced while driving operations are repeated for drivers who have no knowledge of the fuel cut-off function. It is understood that this is a driving operation that can be reduced.

If it is understood, it becomes possible for anyone to naturally perform a driving operation that frequently uses the engine brake by turning off the accelerator and overdrive without using the foot brake frequently on a downhill or the like.

It is characterized in that the calculation of the rate of increase / decrease in carbon emissions is carried out separately.

The present invention eliminates the need for a shaft tachometer that displays the number of revolutions of an automobile engine that encourages sports operation, and allows the instrument panel instrument to “discharge” so that the instrument can be operated while checking the instrument panel speedometer and shift display. By providing standard equipment to display the carbon dioxide emissions, which is a centralized configuration of the "Amount per minute meter", "Emission hourly clock", "Section emission meter", and "Integrated total emission meter" The instrument panel instrument has become an environmentally-friendly display form, and interest in global warming gas has permeated to individuals, and driving operations in consideration of the global environment while confirming carbon dioxide emissions can be expected.

According to the present invention, the amount of carbon dioxide emission is displayed next to the speedometer and shift display of the instrument in the instrument panel, "Emission per minute meter", "Emission hourly clock", "Section emission meter", "Total emission totalization" It is possible to easily confirm and recognize the amount of carbon dioxide emission according to the driving situation from the display form that collects the four "meters".

The displayed values of “Section Emission Meter” and “Total Total Emission Meter” correspond to the “Section Distance Meter” and “Integration Distance Meter” of the speedometer odometer set in the device in advance. Stage of whether or not the operation is performed with the carbon dioxide emission suppressed from the reference value of the carbon dioxide emission (the reference value is the value of the carbon dioxide emission expected according to the distance traveled) Since the judgment of the evaluation by the evaluation display device that determines superiority or inferiority is displayed by the shape of the pattern, the characters, and the color of the illumination, the driver can easily judge whether the driving operation is good or bad.

Further, since the value indicating the magnitude with respect to the reference value is displayed on the digital display device as an increase / decrease rate, detailed judgment can be made. Since the evaluation display device and the display device for the rate of increase / decrease are also integrated in the display device of “Emissions per minute”, it is possible to confirm at a glance, so this was integrated during operation. Using the carbon dioxide display device as an indicator of driving, it is easy for the driver to understand which accelerator operation and shift operation is the optimal operation according to the specified speed of road signs and road markings. Driving operation that can suppress the discharge of wastewater can be expected.

According to the present invention, it is possible to record the total amount of carbon dioxide emitted by a vehicle at the time of a six-month inspection or vehicle inspection, etc. of a vehicle for each period and at the time of scrapping in a record book such as a maintenance notebook. Anyone can recognize how much carbon dioxide has been emitted.

In the case of vehicle inspections, the carbon dioxide evaluation device is used. If the evaluation is bad, the state of the devices related to carbon dioxide emissions, such as the intake system, exhaust system, and drive system, is inspected and maintained more than normal inspection and maintenance. Is the car bad? Or is it the driving skill of the driver? Therefore, if the car is getting worse, adjustments and parts replacement can be carried out effectively and regularly, so that reduction of carbon dioxide emissions caused by poor maintenance can be expected.

In addition, data can be fed back to automobile manufacturers, and carbon dioxide emissions due to different road conditions and road environments due to different use places (regions) for each model name can be understood as experimental data. Therefore, it can be expected that the engine characteristics for reducing the carbon dioxide emission adapted to the place of use and the equipment such as the transmission can be developed suitable for the place of use. In addition, since the data can be left in the record book, it is possible to collect the correlation with the transition of the carbon dioxide emission amount for each vehicle name model, the integrated distance, and the like.

By recognizing the amount of carbon dioxide emitted by the present invention, it is possible to improve the will of the automobile driver who takes the lead in performing maintenance such as tire pressure adjustment, engine oil replacement, and new tire replacement that can reduce carbon dioxide emissions. You can expect.

According to the present invention, the fuel cut-off function during engine braking developed to suppress fuel consumption and the function of suppressing fuel consumption such as lean burn that has improved fuel combustion efficiency have penetrated the entire driver as knowledge. It is considered that the recognition level is low and the driver as a whole does not effectively utilize, for example, the fuel cut-off function.

In the present invention, it is understood that the amount of carbon dioxide emission is eliminated by the accelerator operation and the shift operation during the driving operation because the carbon dioxide emission amount can be recognized in the instrument panel at any time visually. It is expected that the engine will be operated heavily without using the foot brake.

Therefore, even a driver who does not understand the meaning of fuel cut-off can recognize the amount of carbon dioxide emission during driving according to the present invention, so that any driver who does not know the function of fuel cut-off can perform any accelerator operation and shift operation. In some cases, the body will naturally learn that the amount of carbon dioxide emission is lost during driving.

In fact, the engine noise during engine braking is loud, and the rotational speed of the shaft tachometer in the instrument panel is large, so people without knowledge of automobiles consume a lot of fuel and consume it. It is misunderstood as a driving operation that emits a lot of carbon.

Therefore, it is difficult to recognize carbon dioxide emissions from the values of engine sound and shaft rotation speed, and people without knowledge of automobiles will make erroneous judgments. Regardless of the condition, it is possible to visually recognize the carbon dioxide emission in the instrument panel at any time, and the operator's evaluation makes it possible to understand the operation with low carbon dioxide emission.

And it is considered that there will be a new device that suppresses various carbon dioxide emissions that will be developed in the future, the new device has been developed, and the name and function of the device are described in the catalog and explanation of sales of automobile manufacturers Even if the driver who is not understood, such as an instruction manual, can start using the carbon dioxide emission as an index, it is possible to check each carbon dioxide emission during each driving operation even if it can not be understood by the head There is an effect that can be remembered naturally.

In accordance with the present invention, the amount of carbon dioxide emitted from a car traveling on a road can be determined hourly, day of week, weekly, monthly, yearly, regional, by transmitting carbon dioxide emissions to a radio base station. By being able to summarize each graph and the like, it is possible to provide feedback for land readjustment such as administrative city planning and to predict future road conditions, which can be used for road maintenance with low carbon dioxide emissions.

In addition, traffic congestion information of GPS VICS can be transferred to a navigation system because the traffic congestion location of an automobile can be understood based on the increase / decrease rate of the identification number, position information, and carbon dioxide emission.

The best mode for carrying out the invention is shown in the following, the diagram showing the configuration of the instrument panel of the first embodiment of FIG. 1, the diagram showing the configuration of the instrument panel of the second embodiment of FIG. 2, and the control device of FIG. FIG. 4 is a block diagram, FIG. 4 is a flowchart of the first embodiment, FIG. 5 is a flowchart of the second embodiment, FIG. 6 is a configuration diagram of an automobile using wireless means for the mixing ratio detection unit 13, and FIG. The figure which shows the structure of the instrument panel of Example 3, the block diagram of the control apparatus of Example 3 of FIG. 8, the figure which shows the structure of the instrument panel of Example 4 of FIG. 9, and the control apparatus of Example 4 of FIG. Details will be described with reference to a configuration diagram and a flowchart in the case where a wireless unit is used in the mixture ratio detection unit 13 of FIG.

First, description will be made with reference to the drawing showing the configuration of the instrument panel of Embodiment 1 in FIG. The instrument panel's instrument panel 1 carbon dioxide emission display device 2 is configured such that each display device is integrated on the right side of the same panel as the speedometer indicated by the dotted circle, and consumption data for each fuel consumption. The control unit 10 calculates and calculates the value of carbon dioxide emission, and the pointer 5 that operates to draw a circle around the central axis in the output signal of the control unit 10 and the carbon dioxide emission amount of the pointer 5 The carbon dioxide quantity display device which is an analog display of the “per minute emission meter” of the carbon dioxide emission amount which is designed to indicate the scale of the display scale 4 displayed on the circular instrument panel 1 corresponding to the output 3 and the control unit 10 calculates the carbon dioxide by calculating from the consumption data for each fuel consumption corresponding to the “distance distance meter” and the “cumulative distance meter” of the odometers that can be switched in display provided in the speedometer. The amount of discharge is calculated and the controller 10 It is composed of either a digital liquid crystal display, an organic EL display, or an LED display that switches and outputs the "distance emission meter" and "integrated total emission meter" that indicate a long-term state with a force signal. A digital notation type carbon dioxide display device 6 is provided so that a display screen can be stored and displayed at a lower position in the carbon dioxide amount display device 3. The units of the “section emission meter” and the “total emission meter” are displayed on the instrument panel 1 as kg-CO 2.

“Emissions per minute”, which displays the amount of carbon dioxide emitted per minute, is the largest display device on the instrument panel 1 to accommodate the short-term instantaneous emissions and is easy to see. Since the pointer 5 of the carbon dioxide amount display device 3 operates in a circular shape in real time with respect to an instantaneous increase / decrease of the amount, a change based on an accelerator operation, a shift operation, etc. during operation is controlled by the control unit 10. Calculates consumption data for each fuel consumption, calculates carbon dioxide emissions, and the pointer 5 operates within a specified range of 0 to 200 g-CO2 / min with a display scale 4 according to the processed output signal. Outputs and displays carbon dioxide emissions.

In addition, the amount of carbon dioxide emitted per hour for a short time can also be confirmed, and is displayed at the right position of the pointer 5 on the inner side of the same panel as the display scale 4 of the analog display carbon dioxide content display device 3. The display screen of the digital notation type carbon dioxide time display device 7 composed of any one of liquid crystal display, organic EL display and LED display is housed in the device, and the display screen is a fuel based on accelerator operation, shift operation, etc. The control unit 10 calculates the value of the carbon dioxide emission amount from the consumption data for each consumption, and outputs the “emission amount clock” of the carbon dioxide emission amount digitally displayed by the output signal of the control unit 10. It has become. The unit is displayed on the instrument panel 1 as kg-CO2 / h.

In addition, in the lower part of the display device of the digital notation type carbon dioxide display device 6, a reference value of the amount of carbon dioxide that is expected according to the number of mileage of the “section distance meter” and “cumulative distance meter” is shown in the car. A value obtained by calculating the rate of increase / decrease based on the comparison between the reference value and the emission amount calculated at the actual travel distance based on the comparison of the control unit 10 is displayed in detail in the lower row. It is displayed and output as a percentage value with a mark. The unit is displayed on the instrument panel 1 as a percentage.

An evaluation display device 9 adapted to display the driver's evaluation in a stepwise evaluation based on the value of the increase / decrease rate is provided with a display screen housed in the upper position inside the same panel as the display scale 4. .

In this system, the evaluation has three levels, “excellent”, “good”, and “impossible” from the top. The backlight color is “excellent” green, “good” yellow, “impossible” red. Therefore, the color can be easily recognized from the numerical value by the color, the design, and the shape of the character output to the evaluation display device 9.

The higher the evaluation, the more noticeable the symbol becomes larger than the circle. The evaluation is in the above three stages. However, if there is a person who feels that the driver is psychologically “impossible” during driving, the “impossible” evaluation may be omitted. On the other hand, it is better to always have an evaluation of a good judgment such as “excellent” because psychological joy of driving can be obtained.

In addition, as an example of setting the reference value, “excellent” setting lights up with an evaluation of −21% or less from the reference value, “good” setting lights up with an evaluation within ± 20% of the reference value, “impossible” The setting lights up at + 21% or more from the reference value.

The set value of the reference value is set by a program. The numerical value set for comparison with the reference value is an example, and the driver's evaluation for the reduction of carbon dioxide emissions can be optimally evaluated and can be safely driven well without psychological evaluation Set the reference value.

The reference values set by means other than the current 10.15 mode fuel efficiency measurement are predetermined stop and start signals that are close to the general road environment, waiting for traffic lights, hills, curve driving, back, national roads, city roads. The standard value of the amount of carbon dioxide emission corresponding to the travel distance is determined for each vehicle name model by a test that takes into consideration the road environment and road conditions in consideration of town roads, village roads, highways, and traffic jams.

In the case of an engine that burns fossil fuels such as gasoline, light oil, and natural gas, the amount of carbon dioxide emitted is the fuel consumption detector 12 provided in the path through which the fuel passes the amount of fuel discharged from the injection. The flow rate sensor measures the amount of fuel passing through the cylindrical fuel path, and the controller 10 calculates the carbon dioxide emission.

Moreover, when plant fuel such as bioethanol is included in the fossil fuel, the mixture ratio comparison of the mixture ratio detection unit 13 that determines the mixture ratio of the fossil fuel and the plant fuel provided in the path through which the fuel passes is compared. The control unit 10 calculates the flow rate of the fossil fuel and the vegetable fuel by calculating the ratio data of the fossil fuel and the ratio data of the fossil fuel and the vegetable fuel measured by the sensor. And the amount of carbon dioxide emission of fossil fuel and vegetable fuel is calculated.

Each time the fuel consumption of the fuel is calculated by the control unit 10 and the value of the carbon dioxide emission in the storage unit 11 is updated, the carbon dioxide content display device 3, the digital notation type carbon dioxide display device 6, the digital notation type The data of the carbon dioxide time display device 7 is also updated, and the value of the amount of carbon dioxide emission is output by analog processing using the pointer 5 and digital display using each digital notation by the processing of the control unit 10.

Further, the amount of carbon dioxide emitted from the engine that burns hydrogen fuel is determined by the flow rate sensor of the fuel consumption detector 12 provided in the path through which the fuel passes through the fuel consumed by the injection. The amount of fuel passing through the fuel path is measured, and the carbon dioxide emission is calculated by the control unit 10.

In addition, when the fuel path cannot include the mixing ratio detection unit 13 that detects the mixing ratio of fossil fuel and vegetable fuel, the opening / closing sensor that detects the opening / closing of the fueling port is opened at the fueling port. In this case, it is possible to provide an infrared sensor or the like as a wireless means at the sheet metal part of the vehicle body near the fuel filler opening. Details will be described with reference to a configuration diagram of an automobile in which wireless means is used for the mixture ratio detection unit 13 of FIG.

FIG. 6 shows a drawing in which the filler opening cover constituting a part of the vehicle body that is covered so that the filler opening portion is not visible is opened. When using wireless means for the mixing ratio detection unit 13, is the lid filler port cap 18 that can be attached to and detached from the filler port that is open in a circular shape attached? Or has it been removed? An open / close sensor unit 19 composed of an automatic return type sensor switch, an optical sensor switch, or the like that detects this is attached to the vehicle body sheet metal portion on the vehicle body side of the fuel filler opening.

When the fuel filler cap 18 is removed from the fuel filler, the open / close sensor 19 outputs a signal indicating "open" to the controller 10, and the lamp composed of the LED of the indicator lamp 20 is turned on. Then, the fuel in the fuel tank before refueling is measured by a fuel gauge, and the amount of remaining fuel is stored in the storage unit 11.

Then, a person who refuels managing the fuel mixture ratio transmits the mixture ratio to the wireless receiver 21 composed of an infrared sensor or the like adjacent to the fuel filler port by a wireless transmission device provided in the fueling stand. If the signal is received, the voice output A unit 22 constituted by a speaker, a buzzer, etc. outputs a notification of the completion of reception of the mixture ratio data by voice, and the mixture ratio data is stored in the storage unit 11. Yes. In addition, the driver uses a digital notation such as the digital notation type carbon dioxide display device 6 or the digital notation type carbon dioxide time display device 7 in addition to the original display function, and flashes or lights to notify that the mixture ratio data has been received. The mixture ratio data can be displayed for a predetermined time by the processing of the control unit 10.

When refueling is completed and the refueling port cap 18 is attached to the refueling port, the open / close sensor unit 19 outputs a signal indicating “closed” to the control unit 10, and the refueling port is closed by the control unit 10. In this case, the amount of fuel in the fuel gauge is compared with the amount of fuel remaining before refueling to calculate the mixing ratio in the fuel tank, and the storage unit 11 stores and updates the value of the mixing ratio. ing. When the open / close sensor unit 19 outputs a “closed” signal, the function of the wireless reception unit 21 and the control of the indicator lamp unit 20 are turned off and the control unit 10 performs processing so that the power is turned off. Yes.

In addition, the amount of fuel remaining in the fuel tank is measured before fuel supply, and after the fuel supply, the wireless reception unit 21 is used to wirelessly transmit the fuel supply amount data and the mixture ratio data provided in the fuel station. It is also possible to transmit the fuel supply amount data and the mixture ratio data by the apparatus, receive the data by the wireless reception unit 21, and calculate the fuel amount and the mixture ratio in the fuel tank by the control unit 10.

Further, when the opening / closing switch 19 is replaced with the opening / closing of the filling port cap 18 and the opening / closing state of the filling port cover corresponds to the opening / closing state of the filling port cover, the wireless reception unit 21 and the indicator lamp unit 20 It is also possible to turn off the power by turning off the control when it is turned on and in the “closed” state.

In addition, the ETC, which can automatically pay for highway tolls and toll roads, uses the wireless means to receive the fuel amount data and the mixture ratio data at the time of settlement, and automatically compares the remaining amount of the fuel gauge with the amount of fuel at the time of settlement. It is also possible to calculate the value of the mixing ratio.

Each time the fuel consumption of the fuel is calculated by the control unit 10 and the value of the carbon dioxide emission in the storage unit 11 is updated, the carbon dioxide content display device 3, the digital notation type carbon dioxide display device 6, the digital notation type The data of the carbon dioxide time display device 7 is also updated, and the value of the amount of carbon dioxide emission is output by analog processing using the pointer 5 and digital display using each digital notation by the processing of the control unit 10.

When vegetable fuel such as biofuel enters the fossil fuel by the mixing ratio detection unit 13, the fuel consumption meter, the instantaneous fuel consumption meter, and the shaft rotation speed meter (tachometer) cannot recognize the carbon dioxide emission at all. When plant fuel is mixed with fossil fuel at a mixing ratio of 20 to 80 from 100 usage conditions, the fuel consumption meter, instantaneous fuel consumption meter, and shaft rotation speed meter are effective in reducing carbon dioxide emissions. It is difficult to visually recognize the reduction amount in detail, but by providing a display device that displays the carbon dioxide emission amount, it is possible to directly see the carbon dioxide emission amount, so what is a fuel consumption meter and an instantaneous fuel consumption meter? In the idling state where the engine is operated without requiring different driving, the driver can detect the mixing ratio of the vegetable fuel by the control unit 10 by the mixing ratio detection unit 13. By using the “Emissions per minute meter” and “Emissions per hour clock” display devices that show a short-term display that the amount of raw emissions will be reduced by 20%, anyone can read the plant fuel of the fuel. It has become easier to understand the effects of greenhouse gas reduction by using it and it can be realized.

And anyone can read that 20% reduction in carbon dioxide emissions in the actual mileage can be read by the “section emission meter” and “total total emission meter” that show a long time display. It has become easier to understand the effect of reducing greenhouse gases by using fuel, and it can be realized. Therefore, it has the potential to contribute to the spread of bioethanol, a vegetable fuel.

In addition, the amount of CO2 emission reduction due to vegetable fuel can be switched from “Section Emission Meter” and “Total Total Emission” by pressing the switch on the operation unit 8 on the digital notation type carbon dioxide display device 6. Thus, it is possible to display the reduction amount of carbon dioxide in the case of “section emission amount” and “total emission amount” by the processing of the control unit 10.

In addition to the engine using the biofuel of the above plant fuel, when an apparatus for reducing carbon dioxide as a separate substance by chemical change or the like is developed on the exhaust side, for example, a shaft tachometer during idling (tachometer) The number of revolutions is the same, and the car with the same model and engine displacement is 100 g-CO2 / min for the old model, but the new model has another carbon dioxide that can be 50 g-CO2 / min. If a driver changes from an old model to a new model, the reduction in carbon dioxide emissions can be visually observed with a fuel consumption meter, instantaneous fuel consumption meter, or shaft tachometer (tachometer). Although it is not possible to recognize, in the present invention, the setting to reduce the carbon dioxide as a separate substance by chemical change or the like is stored in the storage unit 11, so “emissions per minute” or “emissions per emission” Carbon dioxide emissions are to be able to realize with which it is possible to easily recognize the reductions from anyone old car that has been reduced by the device by a display device of the meter. "

Global warming is possible because anyone can read that 50% reduction in carbon dioxide emissions in the actual mileage is possible with the “section emission meter” and “total total emission meter” that show long-time displays. This makes it easier to understand the effects of gas reduction and allows you to feel it.

The carbon dioxide content display device 3 has a variety of accelerator operations and shift operations for stopping, accelerating and decelerating on roads with traffic lights or intersections such as ordinary roads. The amount of instantaneous discharge can be easily recognized by displaying the amount of discharge.

And the digital notation type carbon dioxide time display device 7 recognizes sensuously by displaying the amount of carbon dioxide emission per hour on a road that can be traveled for a long time at a constant speed with little accelerator operation or shift operation like an expressway. It's easy to do.

From the above, the instrument panel 1 is the carbon dioxide emission display device 2, the carbon dioxide emission amount display device 3 of the “emission amount per minute meter” that displays the emission amount of carbon dioxide per minute, the “zone emission meter” and “ Digital notation type carbon dioxide display device 6 that displays the value of carbon dioxide emissions and rate of increase / decrease of the “total emission meter” and “emission hourly clock” that displays the amount of carbon dioxide emissions per hour The digital notation type carbon dioxide time display device 7 is configured, and the digital notation type carbon dioxide display device 6 and the digital notation type carbon dioxide time display device 7 are integrated inside the display scale 4 of the carbon dioxide amount display device 3. Because it is configured to display information related to carbon dioxide emissions on the same panel, space-saving and efficient visual confirmation and judgment is easy even for people without knowledge of automobile equipment Kill.

The carbon dioxide emission display device 2 is provided with an evaluation display device 9 on the same panel so as to indicate the carbon dioxide emission amount, and the evaluation display device 9 is also a display scale of the carbon dioxide content display device 3. By being configured inside 4, the space-saving and efficient visual confirmation and judgment can be easily performed even for those who have no knowledge of automobile equipment.

The position of the carbon dioxide emission display device 2 in the instrument panel 1 according to the first embodiment is not limited to the right side of the speedometer, but is arranged at a position in the instrument panel 1 that is optimal for each vehicle model. Is. The configuration position and the symbol shape of each display device are not limited to the first embodiment.

Moreover, the combination of the structure of the carbon dioxide emission amount display device 2 can select each display device for each size and shape of the instrument panel 1 and for each vehicle name type.

Further, it is possible to change the analog display of the carbon dioxide amount display device 3 to the instrument panel 1 changed to digital display, or to change the digital display of the digital notation type carbon dioxide time display device 7 to the instrument panel 1 changed to analog display. .

Further, the three-stage evaluation of the evaluation display device 9 of the first embodiment is not limited to this. This is an example, and expressions of evaluation are “EXCELLENCE”, “GOOD”, and “BAD” from the top. Alphabetic characters are also possible, and the present invention is not limited to the color of the backlight, the design and the shape of the characters output to the described display device. And it responds by the instrument panel design according to the model name of the car.

The display scale 4 of the carbon dioxide content display device 3 is determined to be the display scale 4 in the range of the optimal carbon dioxide emission range according to the displacement of the automobile and the vehicle name model, and can be recognized visually by the driver. If there is a shape and notation, it is not limited to this. And it responds by the instrument panel design according to the model name of the car.

Therefore, the present invention uses the signal of the fuel consumption detector 12 that measures the flow rate of the fuel path for supplying fuel to the injector, and uses the signal of the fuel consumption detector 12 to shorten the instrument panel 1 panel equipped with the speedometer of the instrument panel. By the carbon dioxide quantity display device 3 that displays “Emissions per minute” that enables time display and displays instantaneous carbon dioxide emissions, and the digital notation carbon dioxide time display device 7 that displays “Emissions per hour”, When the engine is on and operating, the amount of carbon dioxide emitted from the car is displayed in real time, so that the “emissions per minute” and “emissions per hour” are displayed. By making it possible to perform accelerator operation, shift operation, brake operation, etc. as an indicator of driving operation, make it possible to recognize efficient driving operation that is close to the minimum fuel for automobiles It makes it possible to be implemented can bets.

And even if you do not understand the combustion control of the engine equipped with the carbon dioxide emission suppression such as the fuel cut-off function, in the case of the fuel cut-off function, the control is activated when the engine brake is detected, and the fuel to the injector Since the supply is stopped, the flow rate sensor of the fuel consumption detection unit 12 detects the stop of the flow rate of the fuel supply, and the control unit 10 processes the carbon dioxide by the “discharge amount minute meter” or “discharge amount clock” display device. Emissions will be zero, that is, the value of zero will be zero, and the "total emission meter" and the "total emission meter" will be in a suspended state, so anyone with no knowledge of automobiles and any men and women of all ages It is possible to understand and recognize the equipment and functions that reduce the amount of carbon dioxide emitted from automobiles, so that driving operations can be performed.

In addition, equipment that suppresses carbon dioxide emissions by improving the combustion efficiency of lean burn engines, etc., when the engine control mode changes from normal engine control to lean burn engine control mode, the percentage of air increases and fuel consumption increases. Since the fuel supply to the injector decreases because the control state decreases, the flow sensor of the fuel consumption detector 12 detects that the flow rate of the fuel supply has decreased. Since a decrease in the numerical value of “Emissions every clock” appears and can be felt, if the equipment that controls all carbon dioxide emissions, not just lean burn engines, is in control state, Changes in the numerical values of the "quantity per minute" and "emission hourly clocks" can be experienced while driving, so it is possible to determine which accelerator operation and which shift operation, etc. It is possible for anyone with no knowledge of automobiles about the equipment and functions to suppress the carbon dioxide emissions, and for both men and women of all ages, and anyone can perform driving operations that suppress carbon dioxide emissions It becomes. Therefore, it is a driver-friendly display device that makes it easy to understand and understand the emission amount in detail, rather than providing an indicator lamp that indicates the operating state of the equipment that suppresses the emission of individual carbon dioxide.

In addition, by recognizing the instantaneous change in carbon dioxide emissions on the display device of “Emissions per minute meter” and “Emissions per hour clock”, if you change the tires of a car, etc. Since the superiority and inferiority of the tires appear, it is possible to directly feel that the environment is adversely affected by replacing the standard tires with wheel-in or flat tires.

Therefore, while driving, it is possible to realize and understand the amount of change in the amount of depression of the accelerator and the amount of change due to the flying of the accelerator on the display device related to the fuel consumption such as the fuel consumption meter and the instantaneous fuel consumption meter. However, the “emission amount minute meter” and the “emission amount clock” that display a short time of the carbon dioxide emission amount indicate the fuel discharged from the injector at a predetermined time (for example, every second). The amount of carbon dioxide emission is calculated from the flow rate detected by the flow rate sensor of the fuel consumption amount detection unit 12 provided on the route, so that the accelerator is depressed in the accelerator operation like a shaft tachometer. Since the control unit 10 measures the amount of fuel flow per second in real time corresponding to the amount, the carbon dioxide emission display device 2 During operation the carbon dioxide content display device 3 and the digital representation type carbon dioxide time display device 7 can be an indicator of a driving operation with the speed meter.

The predetermined time for processing in real time by the control unit 10 is 1 second in the example, but the processing interval of the flow rate measurement can be freely set according to the processing capability of the CPU that performs arithmetic processing. However, if the processing interval is increased, the instantaneous accuracy is deteriorated.

And it is considered that the driving skill of the driving operation which suppresses the carbon dioxide emission limit is expected as much as possible in the future, and the instrument panel 1 which displays the carbon dioxide emission amount at the driving school or the like when acquiring the automobile license. The CO2 emission display device 2 is equipped so that the current instruments that cannot visually recognize carbon dioxide emission due to practical skills explain the operation operation with low carbon dioxide emission and the fuel cut off function by engine brake, etc. Although it is difficult to easily understand by practical instruction, it is easy to give practical guidance to driving operation with confirmation while showing the carbon dioxide emission display device 2. This makes it possible to learn driving operations that can suppress the problem before graduation. Because of this effect, new drivers after obtaining a car license can start driving operations to reduce carbon dioxide emissions from the beginning.

Further, in the present invention, the signal of the fuel consumption detector 12 that measures the flow rate of the fuel path for supplying the fuel to the injector is used for the long time to the instrument panel panel equipped with the instrument panel speedometer. The digital notation type carbon dioxide display device 6 that can display the “distance emission amount” that displays the emission amount of carbon dioxide at the section distance at the actual travel distance and the “total emission amount of accumulation” of the integration distance. When the vehicle is operating with ON, if the vehicle emits carbon dioxide, the value stored in the digital notation carbon dioxide display device 6 in the storage unit 11 is stored and updated regardless of whether or not the vehicle is running. The amount is integrated and displayed in real time.

In addition, the value of the “distance emission amount” of the interval distance and the “total emission amount of integration” of the integrated distance of the digital notation type carbon dioxide display device 6 that indicates the emission amount of carbon dioxide of the actual travel distance by the processing of the control unit 10. Using the reference value (the reference value is the value of the amount of carbon dioxide that is expected according to the distance traveled) and the amount of increase or decrease calculated by comparing the amount of carbon dioxide emitted during the actual distance traveled By providing the display device and the evaluation display device 9 for performing the stage evaluation of “excellent”, “good”, and “impossible” processed using the increase / decrease rate on the same panel of the instrument panel, the driver can The “section emission amount” can be arbitrarily evaluated every day, and the “total accumulated emission amount” is evaluated with respect to the total carbon dioxide emission amount. Evaluation of the quality of driving skills It is adapted to be.

The stage evaluation of the evaluation display device 9 is based on the estimated value of carbon dioxide emission according to the distance traveled in consideration of the road environment and road conditions for each car model and car model. The standard value for each formula and car name model is evaluated fairly.

Next, a diagram illustrating the configuration of the instrument panel of the second embodiment in FIG. 2 will be described. In the second embodiment, by operating the switch of the operation unit 8, the display of the carbon dioxide emission amount display device 3 of the carbon dioxide emission amount shown in the first embodiment can display the shaft rotation speed of the engine. .

In this case, the control of the pointer 5 is switched from the signal of the carbon dioxide emission amount to the signal corresponding to the shaft tachometer at the judgment of the control unit 10, and the display scale 4 of the carbon dioxide emission amount displayed on the instrument panel 1. The display scale 4 is switched from 0 to 10 and the unit of x1000 rpm / min according to the judgment of the controller 10 so that the unit g-CO2 / min indicates the shaft rotation speed, and the shaft rotation speed of the engine is changed. It can be displayed.

The display showing the shaft rotation speed, the digital notation carbon dioxide display device 6 and the digital notation carbon dioxide time display device 7 can be displayed together. And the evaluation of the same evaluation display apparatus 9 as Example 1 is also output.

When it is desired to provide a conventional display of the shaft rotation speed in the instrument panel 1, the same saving in the instrument panel 1 is provided by providing a display switching function in the instrument panel 1 by operating the operation unit 8 as in the second embodiment.

The set value of the effective range is a value of carbon dioxide emission indicating the short time of the carbon dioxide amount display device 3 of “Emissions per minute” or the digital notation type carbon dioxide time display device 7 of “Emissions per hour clock” The effective range setting value is set for each gear ratio.

For example, the effective range setting value is set to 0 to 50 g-CO2 / min in the case of neutral, and the setting value is set to 0 to 130 g-CO2 / min in the case of the first speed ratio. When 24 is neutral, the driver blows the engine and the carbon dioxide emission becomes 50.1 g-CO2 / min or more, or when the gear ratio is 1st, the carbon dioxide emission is 130. When it becomes more than 1g-CO2 / min, the control unit 10 judges that it is excessive (excessive emissions) and informs the driver that the accelerator operation and the shift operation are performed to exhaust the carbon dioxide emissions excessively. The determination display device unit 23 to be lit is turned on.

By setting the operation unit 8 so that the increase / decrease rate can be easily recognized without resetting the value and visually confirming the value, the instrument panel 1 is set to the right side of the “Emissions per minute”. The increase / decrease rate can be output by voice from the provided speaker.

When the engine is operated, the controller 10 calculates the increase / decrease rate of carbon dioxide automatically according to the actual travel distance from this place. Although the increase / decrease rate is not displayed on the digital notation type carbon dioxide display device 6, if the operation of the engine is stopped and the engine stop is judged by the control unit 10, the increase / decrease rate of the carbon dioxide up to the stop position is spoken by voice. It outputs more and notifies the driver. Therefore, as a simple means, it is possible to output the value of the carbon dioxide increase / decrease rate during ON / OFF of the engine operation without resetting the “section emission meter” every day for driving practice or emission check. It is like that.

In addition to the rate of increase / decrease, the content output from the speaker can output the actual travel distance, the amount of carbon dioxide emission, and the evaluation content of the stage evaluation by voice processing through the processing of the control unit 10.

First, the amount of carbon dioxide emission per minute is calculated from the value of consumption at predetermined intervals (for example, every second) derived every time the consumption of fossil fuel or hydrogen fuel is calculated (S207). The pointer 5 of the carbon dioxide content display device 3 of the display device which is an analog display is operated according to the discharge amount by the driving device and displays the value of the display scale 4 (S208). .

Second, the amount of carbon dioxide emission per hour is calculated from the value of consumption at predetermined intervals (for example, every second) derived every time the consumption of fossil fuel or hydrogen fuel is calculated (S212). In addition, the digital notation of the digital notation type carbon dioxide time display device 7 of the display device which is a digital display operates according to the discharge amount and is displayed as a digital numerical value (S213).

The third is a digital notation type carbon dioxide in which the total emission amount of the carbon dioxide emission amount from the production of this automobile to the present is stored in the storage unit 11 and the total emission amount is displayed. The display device 6 is configured to output a digital display in response to switching of the display screen by selection based on the operation of the operation unit 8.

The total emission amount of carbon dioxide is calculated (S214) from the consumption value at predetermined intervals (for example, every second) derived for each calculation of the consumption amount of fossil fuel and hydrogen fuel, and stored in the storage unit 11. The new total emission value is added to the previous total emission value stored and updated (S215), and the latest total stored carbon dioxide emission is digitally displayed on the display device. The digital notation of the carbon dioxide display device 6 operates in accordance with the discharge amount and is displayed as a digital numerical value (S216).

Then, the increase / decrease rate is calculated from the setting of the reference value of the total discharge amount of carbon dioxide with respect to the total travel distance, that is, the integrated distance stored in the storage unit 11 (S217), and the value of the increase / decrease rate is calculated in the storage unit 11 for each calculation. The storage is updated (S218), and the driver's stage evaluation indicating the evaluation of superiority or inferiority of the total discharge amount of carbon dioxide with respect to the integrated distance is determined by the control unit 10.

And when this display is selected with the operation part 8, the total discharge | release amount of the integrated carbon dioxide is displayed on the digital notation type | formula carbon dioxide display apparatus 6, and the value of an increase / decrease rate is displayed on the lower stage. And a driver | operator's stage evaluation is displayed according to evaluation of the evaluation display apparatus 9 (S219).

The fourth is a digital notation type dioxide dioxide which is designed to integrate and store the carbon dioxide emissions in the section corresponding to the section distance meter of the speedometer of the automobile and store it in the storage unit 11. The carbon display device 6 is configured to output a digital display in accordance with the switching of the display screen by selection based on the operation of the operation unit 8.

The section emission amount of carbon dioxide is calculated (S220) from the consumption value at predetermined intervals (for example, every second) derived for each calculation of the consumption amount of fossil fuel and hydrogen fuel, and stored in the storage unit 11. The new section emission value is stored and updated by adding to the section emission value being stored (S221), and the stored latest carbon dioxide section emission is digitally displayed. The digital notation of the carbon dioxide display device 6 operates in accordance with the discharge amount and is displayed as a digital numerical value (S222).

Then, the increase / decrease rate is calculated from the setting of the reference value of the carbon dioxide emission amount with respect to the section distance stored in the storage unit 11 (S223), and the increase / decrease rate value is stored and updated in the storage unit 11 for each calculation (S224). ), The control unit 10 determines the driver's stage evaluation indicating the superiority or inferiority of the carbon dioxide emission with respect to the section distance.

And when this display is selected with the operation part 8, the discharge | emission amount of the carbon dioxide discharged | emitted in the area is displayed on the digital notation type carbon dioxide display apparatus 6, and the value of an increase / decrease rate is displayed on the lower stage. And a driver | operator's stage evaluation is displayed according to evaluation of the evaluation display apparatus 9 (S225).

In addition, the digital notation type carbon dioxide display device 6 is linked to the operation of the operation unit of the speedometer for switching the display indicating “section distance meter” and “integrated distance meter” provided in the speedometer. When “distance distance meter” is selected, the digital notation type carbon dioxide display device 6 switches to the display screen of “distance emission meter” of carbon dioxide, and the backlight color of the display screen changes to orange.

When “Integrated distance meter” is selected, the display screen of the “total integrated emission meter” of carbon dioxide is switched, and the backlight color of the display screen is switched to green, thereby reducing the troublesome operation. It is possible to confirm both numbers at the same time at a glance as well.

When the section distance is reset in the case of the “section distance meter”, the digital notation type carbon dioxide display device 6 is set so that the section emission value of the “section emission meter” of carbon dioxide is reset to zero. It has become.

In addition, when “accumulated distance” and “total accumulated discharge amount” are described in a record book such as a maintenance notebook, a display error does not occur because the display screen is switched. In addition, the section discharge amount and the total total discharge amount can be identified by the color of the backlight of the display device.

Next, a flowchart in the case where wireless means is used for the mixture ratio detection unit 13 in FIG. 11 will be described. This is a means when the mixture ratio detector 13 does not use a mixture ratio comparison sensor that directly detects the mixture ratio from the fuel in the fuel path or the fuel tank. Therefore, (S101) to (S102) in the flowchart diagram of the first embodiment in FIG. 4 and (S201) to (S202) in the flowchart diagram of the second embodiment in FIG. .

Is the fuel filler cap part 18 removed from the fuel filler opening by the open / close sensor part 19 that detects the state of the fuel filler cap part 18 of the lid by opening the filler cover that forms part of the body of the automobile? The control unit 10 determines (S301).

And when the control part 10 judges that the fuel filler cap part 18 is removed from the fuel filler, the lamp | ramp comprised by LED etc. of the indicator light part 20 near a fuel filler will light (S302). It has become.

Then, the control unit 10 automatically measures the amount of fuel remaining in the fuel tank from the fuel gauge provided in the fuel tank (S303) and stores it in the storage unit 11. And the radio | wireless receiving part 21 will be in an operation state (S304).

Then, the wireless reception unit 21 waits to receive the mixture ratio data (S305), and transmits the mixture ratio data to the wireless reception unit 21 from the wireless transmission device that transmits the mixture ratio data provided in the gas station. The control unit 10 stores the mixture ratio data in the storage unit 11 (S306).

When the filler cap 18 is attached (S307), the value of the mixture ratio before the memory update is automatically updated from the fuel gauge, the amount of fuel remaining in the fuel tank, and the newly transmitted mixture ratio data The mixing ratio of fossil fuel and vegetable fuel is calculated from the amount of fuel in the fuel tank increased by refueling (S308), and the value of the mixing ratio in the storage unit 11 is stored and updated (S309).

According to the present invention, it is considered that equipment for reducing carbon dioxide emissions, fuel cut-off and lean burn engines, and various other equipment will be developed in the future. Even if it is not understandable by the manual etc., the confirmation of the amount of carbon dioxide emission in the instrument panel 1 equipped with a speedometer is "Emission per minute meter", "Emission hourly clock", "Section emission meter", " Each display function of the “total emission meter” can be recognized during operation, and the short-term carbon dioxide emissions can be easily understood by visual inspection of the “emissions minute meter” and “emission hourly clock”. The long-distance stable driving operation can be handled from the driving operation.

The long-term emission of carbon dioxide allows the driver to visually recognize the “distance emission” and the “total emission” so that the driver can judge whether the operation is good or bad for each zone. Can make bad judgments.

In addition, the above-mentioned judgment is provided on the instrument panel 1 with a display device for displaying the evaluation of the driver's “section emission” and “total emission”, so that the accelerator operation or shift based on the carbon dioxide emission is used. The driving operation is learned by the driver. And wasteful discharge of carbon dioxide can be prevented.

The “section emission meter” allows the driver to recognize the amount of carbon dioxide emission for each section that the driver wants to measure arbitrarily, and the driver can perform daily driving so that the evaluation judgment of the evaluation display device 9 can be improved. It becomes possible to study the driving skill of operation.

Then, the total carbon dioxide emissions emitted over the total accumulated distance that this vehicle has been shipped and traveled to date can be visually recognized by the “total emission meter”. By being able to recognize how much carbon dioxide has been discharged, if the engine is on and carbon dioxide is discharged in the operating state, it will be integrated into the “total emission” parking lot It can be expected to suppress driving operations such as idling neglected, sudden acceleration, and flying sky often seen on roads.

Therefore, according to the present invention, in the current shaft rotation speed meter (tachometer), fuel consumption meter, and instantaneous fuel consumption meter, the amount of carbon dioxide emitted by the driver actually depends on the driver's accelerator operation, shift operation, brake operation, and the like. This makes it difficult for drivers who are unable to understand which driving operation can reduce the amount of carbon dioxide emissions and how to drive the vehicle. It is possible to provide an environment that can be recognized and judged.

And it is also considered that there is a driver whose meaning of fuel consumption is not understood. Even if an instrument panel equipped with a current speedometer is equipped with a shaft tachometer, a fuel consumption meter and an instantaneous fuel consumption meter, all men and women of all ages This is not a friendly instrument panel that allows drivers to recognize carbon dioxide emissions, making it difficult for drivers to take action to reduce carbon dioxide emissions to prevent global warming. This makes it possible to provide an environment where drivers who make it difficult to share their feelings can easily recognize the amount of carbon dioxide emissions and make judgments.

In addition, if the driver's evaluation of carbon dioxide emissions is “excellent”, this will prove that the driver's driving skill is excellent at every vehicle inspection, and will not interfere with driving. A sticker that proves that the driving skill is excellent is put on the glass on the front or rear surface of the car at the location and commended.

For example, characters such as “CO2”, “Excellent”, and “Skill” are designed on the design of an image of the earth so that it can appeal that it is driving in consideration of the global environment. Since the above evaluation is appealing to automobiles, it is possible to judge who is excellent, so those who have received excellent evaluation also suppressed carbon dioxide by teaching environmentally friendly driving skills to those who wish By increasing the number of drivers, it is possible to reduce carbon dioxide emissions. We can expect the effect that said.

The evaluation of the driving skill of the above-mentioned driving operation can be carried out by the country or administrative organization by determining the evaluation setting of the evaluation display device 9 for each vehicle name type, and the country or administrative organization can make public evaluation such as the Internet. By providing information exchanges that can be performed, people who have an “excellent” rating for each vehicle model can also teach driving operations nationwide, and those who do not have a good rating can consult It is also possible to discuss driving operations that reduce carbon dioxide emissions, and the more people who are concerned about the evaluation of the same model name, the more carbon dioxide emissions can be reduced. There is growing interest and this will further reduce carbon dioxide emissions from cars.

For example, the model name of car A is a highway with a carbon dioxide emission rate of 70 km / h and 100 g-CO2 / min between 80 km / h and 100 km / h abruptly 40 g-CO2 / min. It becomes possible to exchange information such as the function that reduces

Therefore, the instrument panel 1 can recognize the carbon dioxide emission to the driver who drives the car so that anyone who has no knowledge about the equipment and functions of the automobile and any man and woman of all ages can reduce the carbon dioxide emission. An environment where the operation can be easily understood and reduced by the experience of the operation using the carbon dioxide display device 2 of the instrument panel 1 as an index by understanding and improving the environment. Therefore, it is possible to realize a driving operation without excessively discharging carbon dioxide by the driver.

In addition, the service is marked with an award to evaluate the ability to drive with reduced carbon dioxide emissions on the front or back of the driver's license. As the number of drivers for this purpose increases, the amount of wasteful carbon dioxide emissions increases and the reduction becomes possible.

If the driver's evaluation of carbon dioxide emissions is “excellent”, those who receive this award will be able to obtain benefits such as a reduction in automobile tax at the time of vehicle inspection and services from automobile manufacturers. .

Currently, the national government and administrative organizations are implementing tax incentives to reduce automobile tax on automobiles with good fuel economy as XX year compatible cars, but it is difficult to stop the automobile society as a whole and driving that is a consumer The lack of measures to reduce carbon dioxide after the purchase of the driver is considered to be a stop for the entire automobile society, and if the driver is not conscious of reducing carbon dioxide, fuel efficiency is good. Since it is not possible to prevent cases where idling is left unattended, abusing, sudden acceleration, etc., or remodeling or doing bad things to the global environment, the evaluation results of the evaluation display device 9 at the time of vehicle inspection Based on the above, by making tax incentives to reduce automobile weight tax and automobile tax, drivers can be encouraged to reduce carbon dioxide emissions and be a goal to reduce It may be pawl more carbon dioxide emissions.

As a result, driving operations that reduce carbon dioxide emissions are promoted by the display device and evaluation of carbon dioxide, and driving operations that reduce carbon dioxide emissions are also promoted by awards. Reducing carbon dioxide emissions of chemical gas can be expected to lead to national movements in driving operations.

In addition, at the time of vehicle inspection, the Land Transportation Bureau in each prefecture makes it possible to record the total distance and “total emissions” in the record book for each year and vehicle name type, and the year in each region. By managing the formula and vehicle name type together, the correlation between the accumulated distance and the total accumulated emissions can be summarized in a graph, thereby verifying regional differences for each year type and vehicle name type. It becomes possible.

Verification of carbon dioxide emissions with respect to the mileage inspected before shipment for each vehicle model and “total accumulated emissions” of carbon dioxide in the accumulated distance of actual travel emitted by various drivers, both young and old It is also possible to do. As supplementary data, more detailed statistical verification can be performed by adding a parameter for verifying the amount of reduction by vegetable fuel.

Based on the verification results of the total distance and “total emissions”, the location of use is identified from the location of the headquarters of use and the vehicle inspection location described in the vehicle verification, and the road conditions (average traffic time difference or average Driving speed, etc.) and road environment (average slope of road, maximum speed of road, etc.) can be used to verify carbon dioxide emissions. Development that is adapted to each region, such as engine characteristics, drive device, transmission, etc., becomes possible, and it is possible to further reduce the amount of carbon dioxide emission reduction. Moreover, it becomes possible to summarize in more detail according to sex and age.

In addition to the above description, carbon dioxide emissions, particularly “total accumulated emissions”, are stored in the storage unit 11 and displayed on the digital notation carbon dioxide display device 6. Accurate information on the state of the engine can only be confirmed by the odometer's total distance and the year of the car (the engine sound becomes quieter when the oil is changed or additives are added, However, it cannot be accurately determined.)

The current accumulated distance is not the only way to know the state of use of the engine. For example, if only the accumulated distance is recorded, even if the accumulated distance is short, the engine usage time (such as cars with a lot of idling) is long. Although it is impossible, the total amount of carbon dioxide accumulated remains in the memory and is displayed on the display screen, so that everyone can know the correct use state of the engine.

For example, in a car model of the same model year, the longer the accumulated distance but the smaller the total carbon dioxide emission, the shorter the accumulated distance, but the shorter the total operating time of the engine than the automobile with the larger total carbon dioxide emission. It is understood that the degree is good.

Also, in the used car market, the state of the engine can compare the accumulated distance with the “total accumulated emissions”, so is this car an eco-friendly engine for anyone of all ages and men? Or did you drive badly in an environment where idling was left unattended in the environment, flying in the sky, suddenly starting or accelerating frequently? Can be estimated, and a correct judgment can be made about the engine state.

Therefore, an erroneous determination occurs only with the current accumulated distance, but since there is a display device for the amount of carbon dioxide emission, the total amount of carbon dioxide emission can be added to the index, so that By comparing the total amount of emissions, anyone can understand the exact state of use of the engine.

In addition, in the case of people who cannot inevitably compare the integrated distance and the total emission amount of carbon dioxide, it is possible to easily make a determination on the display device of the evaluation display device 9 that displays the stage evaluation with respect to the set reference value. If it is desired to make a more detailed determination than the stage evaluation, a detailed determination can be made based on the value of the increase / decrease rate displayed on the display device of the digital notation type carbon dioxide display device 6.

Therefore, by using the carbon dioxide emissions as an index, this kind of usage is newly born. In addition, when you let go of a trade-in or sale of a car, the total amount of carbon dioxide emissions will be an indicator for assessment, so if anyone gives up their own car, they will be assessed financially Since the evaluation is desired to be better, the effect of constantly reducing carbon dioxide emissions will work during operation.

Therefore, it is considered that the emission reduction of carbon dioxide from the automobile, which is a global warming gas, can be achieved by providing the instrument panel 1 with the carbon dioxide emission display device 2 according to the present invention.

According to the present invention, the current automobile is not easy to operate and is not an easy-to-operate automatic car like a manual car, and anyone can easily drive it, but on the other hand, it corresponds to the driver's carbon dioxide emission Other than the will of reduction, there are people who are familiar with the equipment and functions of the car, while there are people who are not familiar with the driver, and the driver is driven by various people with a wide age range of young and old. Driving operation to reduce carbon dioxide emissions by providing the instrument panel 1 with a carbon dioxide emission display device 2 that shows that the difference in the ability of driving skills of operation greatly affects the carbon dioxide emissions. It becomes possible to reduce the difference in ability of driving skills. This makes it possible to reduce carbon dioxide emissions from automobiles.

And it becomes possible to share the awareness of the supervisor's country, government agencies, suppliers 'automakers and consumers' drivers (users) to reduce carbon dioxide, and change the national awareness of carbon dioxide. By becoming a means of encouraging, the automaker developed a car with performance in consideration of the global environment, so that the driver can drive a car with good performance with driving skill to reduce carbon dioxide, It is possible to achieve the Trinity to reduce carbon dioxide emitted from automobiles.
