DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Embodiment 1 First, with reference to FIG. 1, a mobile body equipped with an air purifying device 12 according to the first embodiment will be described. FIG. 1 is a schematic side view of a mobile body equipped with an air purifying device 12 according to the first embodiment. As shown in FIG. 1, a vehicle 1 as a mobile body according to the first embodiment includes an air purifying device 12 mounted on a vehicle body 11. For example, the air purifying device 12 is detachably held on the vehicle body 11. The air purifying device 12 is configured to take in air A1 outside the vehicle 1 through an intake port 12a, remove some or all of specific substances or particles that degrade air quality from the taken-in air, and discharge air A2 with improved air quality from an exhaust port 12b. For example, the air purifying device 12 takes in air by natural intake according to the airspeed of the vehicle 1 while the vehicle 1 is moving forward, and discharges the air by natural exhaust. Note that in the first embodiment, specific substances or particles that degrade air quality are also referred to as "air quality degraders." Furthermore, among the substances that degrade air quality, specific substances or particles that are to be removed by the air purifying device 12 are also referred to as "substances to be removed."

[0010] For example, the air purifying device 12 captures the substances to be removed contained in the taken-in air by filtering them with a filter. Alternatively, for example, the air purifying device 12 captures the substances to be removed contained in the taken-in air by adsorbing them to a charged filter. Alternatively, for example, the air purifying device 12 captures the substances to be removed contained in the taken-in air by adsorbing them to a charged electrode. Alternatively, for example, the air purifying device 12 decomposes the substances to be removed contained in the taken-in air using an oxidation-reduction catalyst. Alternatively, for example, the air purifying device 12 removes the substances to be removed, i.e., gases, contained in the taken-in air, by adsorbing, absorbing, or decomposing them.

[0011] Air purifier 12 may have any one of the above-mentioned functions, or may have multiple functions among the above-mentioned functions, or may remove some or all of the substances to be removed from the air taken in by a function other than the above-mentioned functions. The substances to be removed by air purifier 12 include, for example, ozone, carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides, hydrocarbons, PM10, PM2.5, pollen, yellow sand, volcanic ash, aerosols, microplastics including tire wear particles, and other chemical substances or particles that degrade air quality. Air purifier 12 may be configured to remove only one of these substances to be removed from the air, or may be configured to remove multiple of these substances to be removed from the air.

[0012] The vehicle 1 also includes an information processing device 100 and a display device 60. The display device 60 displays an image generated based on information from the information processing device 100. For example, the display device 60 is disposed on an instrument panel (not shown) of the vehicle 1, and displays an image relating to the improvement in air quality achieved by the air purifying device 12 so that the image can be viewed by the user of the vehicle 1. Details of the information processing device 100 and the display device 60 will be described later.

[0013] Next, a schematic configuration of an information processing system according to embodiment 1 will be described with reference to Figures 1 and 2. Figure 2 is a block diagram showing a schematic configuration of the information processing system according to embodiment 1. As shown in Figure 2, the information processing system according to embodiment 1 includes a positioning device 20, a mobile object information detection device 30, an air quality detection device 40, a database 50, a display device 60, and an information processing device 100, which are connected wirelessly or by wire so as to be able to communicate with each other.

[0014] The positioning device 20 measures the position of the vehicle 1. For example, the positioning device 20 has a GNSS (Global Navigation Satellite System) receiver, receives GNSS signals from GPS (Global Positioning System) satellites, and measures the absolute position and time of the vehicle based on the received signals. The positioning device 20 outputs positioning information, which is the positioning result of the vehicle 1, to the information processing device 100.

[0015] The mobile object information detection device 30 detects the operation and state of the vehicle 1. For example, the mobile object information detection device 30 includes sensors such as a rotation speed sensor for detecting the rotation speed of the tires of the vehicle 1, a speed sensor for detecting the speed of the vehicle 1, an acceleration sensor for detecting the acceleration received by the vehicle 1, a gyro sensor for detecting the angular velocity of the vehicle 1, a sensor for detecting the position of the shift lever of the vehicle 1, a sensor for detecting the position of the accelerator pedal of the vehicle 1, a sensor for detecting the position of the brake pedal of the vehicle 1, a weight sensor for detecting the weight of loads including passengers carried by the vehicle 1, a sensor for detecting the energy consumption of the vehicle 1, a sensor for detecting the cumulative usage time of the air purification device 12, and a sensor for detecting the amount of air taken in by the air purification device 12, and outputs information indicating the detection results of these sensors to the information processing device 100.

[0016] The air quality detection device 40 is a device for detecting substances to be removed that are contained in the air. For example, the air quality detection device 40 is disposed near the intake port 12a of the air purifier 12, detects substances to be removed that are contained in the air taken in by the air purifier 12, and outputs information indicating the detection results to the information processing device 100. Alternatively, for example, the air quality detection device 40 is disposed near the exhaust port 12b of the air purifier 12, detects substances to be removed that are contained in the air discharged from the air purifier 12, and outputs information indicating the detection results to the information processing device 100. Alternatively, for example, the air quality detection device 40 is disposed in an area that includes at least a part of the travel route along which the vehicle 1 travels, detects substances to be removed that are contained in the air in the area according to the location where the air quality detection device 40 is disposed, and outputs information indicating the detection results to the information processing device 100.

[0017] The air quality detection device 40 may be configured to detect substances to be removed contained in any one of the air taken in by the air purifying device 12, the air discharged from the air purifying device 12, and the air in an area including at least a part of the travel route along which the vehicle 1 travels, or may be configured to detect substances to be removed contained in more than one of these air sources. In the first embodiment, the area including at least a part of the travel route along which the vehicle 1 travels is also referred to as the "target travel area."

[0018] The database 50 stores various types of information used by the information processing device 100 for processing. For example, the database 50 stores information indicating the performance of the vehicle 1. Specifically, the database 50 stores information indicating the performance of the vehicle 1, such as the energy consumption per unit travel distance of the vehicle 1, the amount of air quality degrading substances emitted per unit fuel consumption of the vehicle 1, and the amount of tire wear per unit travel distance of the vehicle 1. Also, for example, the database 50 stores information indicating the performance of the air purifying device 12. Specifically, the database 50 stores information indicating the amount of substances to be removed by the air purifying device 12 per unit travel distance of the vehicle 1, and the amount of air taken in by the air purifying device 12 per unit travel distance of the vehicle 1. Also, for example, the database 50 stores information indicating the useful life of parts of the vehicle 1, including the air purifying device 12.

[0019] Furthermore, for example, the database 50 stores information on substances that degrade air quality, such as the trading price of greenhouse gases in the carbon credit market, the costs of collecting and disposing of substances that degrade air quality, and the amount of economic loss caused by the environmental load caused by substances that degrade air quality. Furthermore, for example, the database 50 stores reward acquisition condition information related to the conditions for acquiring rewards that a user of the vehicle 1 can acquire based on the use of the air purification device 12. The information stored in the database 50 is updated as needed based on information from an input device (not shown) that accepts input operations by an operator and information from other devices (not shown) connected via a communication network.

[0020] For example, the map information stored in database 50 includes road information including information on the location of roads, road shapes, road types, and intersection locations in the travel area; facility information including information on the names, types, and locations of facilities; topographical information including information on the shapes of mountains, rivers, and coastlines; and other information.

[0021] The display device 60 acquires information from the information processing device 100 and displays the acquired information as visual information, thereby notifying the user of the vehicle 1 of the information from the information processing device 100. For example, the display device 60 is configured with a liquid crystal display panel, an organic or inorganic EL (Electroluminescence) panel, a dot matrix display, an LED (Light Emitting Diode), or other device that displays information as visual information. The display device 60 may have an input device (not shown) configured as a touch panel or a keyboard, or may have a speaker (not shown) that can output sound based on the information from the information processing device 100.

[0022] The information processing device 100 includes a positioning information acquisition unit 101, a map information acquisition unit 102, a mobile object information acquisition unit 103, an air quality degradation information acquisition unit 104, an air quality improvement information acquisition unit 105, a reward acquisition condition information acquisition unit 106, a reward acquisition determination unit 107, a reward information generation unit 108, and a display control unit 109.

[0023] The positioning information acquisition unit 101 acquires positioning information of the vehicle. For example, the positioning information acquisition unit 101 acquires positioning information indicating the absolute position of the vehicle using latitude and longitude and time information indicating the positioning time based on information from the positioning device 20. Note that the positioning information acquisition unit is not limited to acquiring positioning information based only on the GNSS signal from the positioning device 20. The positioning information acquisition unit may be configured to acquire positioning information based on other information. For example, the positioning information acquisition unit may be configured to acquire positioning information based on information such as the speed and acceleration of the vehicle 1 acquired by the mobile object information acquisition unit 103, or may be configured to acquire positioning information based on the information acquired by the mobile object information acquisition unit 103 and the GNSS signal, or may be configured to acquire positioning information using RTK (Real Time Kinematic)-GNSS that corrects the GNSS signal based on a signal transmitted from a base station (not shown), or may be configured to acquire positioning information using a high-precision locator (not shown) provided in the vehicle.

[0024] The map information acquisition unit 102 acquires map information from the database 50. For example, the map information acquisition unit 102 acquires map information of the periphery of the vehicle 1 from the database 50 based on the position of the vehicle 1 indicated by the positioning information acquired by the positioning information acquisition unit 101.

[0025] The mobile object information acquisition unit 103 acquires mobile object information about the vehicle 1 based on information from the mobile object information detection device 30 and the database 50. For example, the mobile object information acquisition unit 103 acquires mobile object information about the vehicle 1, such as information indicating the travel distance of the vehicle 1 and the energy consumption of the vehicle 1, information about the performance of the vehicle 1, information indicating the amount of air quality degrading substances emitted during the manufacture of the vehicle 1 and the amount of air quality degrading substances emitted as the vehicle 1 is operated, and the accumulated usage time of the air purifying device 12. Note that the mobile object information acquisition unit 103 may be configured to acquire only one of these pieces of information, or may be configured to acquire multiple pieces of information.

[0026] The air quality degradation information acquisition unit 104 acquires air quality degradation information indicating the amount of degradation in air quality caused by the vehicle 1. For example, the air quality degradation information acquisition unit 104 acquires air quality degradation information indicating the amount of degradation in air quality caused by the movement of the vehicle 1 based on the amount of air quality degradants emitted as the vehicle 1 moves. For example, air quality degradants emitted as the vehicle 1, which is an internal combustion engine vehicle, moves include air quality degradants emitted when fuel is burned and tire wear debris generated during driving. Furthermore, for example, air quality degradants emitted as the vehicle 1, which is an electric vehicle, moves include tire wear debris generated during driving. Note that in the first embodiment, the air quality degradation information indicating the amount of degradation in air quality constitutes air quality change information indicating the amount of change in air quality.

[0027] For example, the air quality degradation information acquisition unit 104 acquires the amount of air quality degrading substances emitted as the vehicle 1 moves based on the information acquired by the mobile object information acquisition unit 103, and acquires air quality degradation information indicating the amount of degradation in air quality associated with the movement of the vehicle 1 based on the amount of air quality degrading substances emitted as the vehicle 1 moves. Specifically, the air quality degradation information acquisition unit 104 acquires air quality degradation information indicating the amount of degradation in air quality associated with the movement of the vehicle 1 based on information acquired by the mobile object information acquisition unit 103 indicating the travel distance of the vehicle 1, the fuel consumption per unit travel distance of the vehicle 1, and the amount of air quality degrading substances emitted per unit fuel consumption of the vehicle 1, and information acquired by the mobile object information acquisition unit 103 indicating the amount of tire wear per unit travel distance of the vehicle 1.

[0028] Furthermore, for example, the air quality degradation information acquisition unit 104 acquires air quality degradation information indicating the amount of degradation in air quality at the time of manufacturing the vehicle 1, based on the amount of air quality degraders emitted during the manufacturing of the vehicle 1. For example, air quality degraders emitted during the manufacturing of the vehicle 1 include air quality degraders emitted from the production factory of the vehicle 1, and air quality degraders emitted during the transportation of the vehicle 1, vehicle 1 parts, and vehicle 1 materials. For example, the air quality degradation information acquisition unit 104 acquires air quality degradation information indicating the amount of degradation in air quality at the time of manufacturing the vehicle 1, based on information indicating the amount of air quality degraders emitted during the manufacturing of the vehicle 1, acquired by the mobile object information acquisition unit 103.

[0029] Furthermore, for example, the air quality degradation information acquisition unit 104 acquires air quality degradation information indicating the amount of degradation in air quality associated with the operation of the vehicle 1, based on the amount of air quality degradants emitted in conjunction with the operation of the vehicle 1. For example, air quality degradants emitted in conjunction with the operation of the vehicle 1, which is an internal combustion engine vehicle, include air quality degradants emitted during the mining of fuel consumed by the vehicle 1, the refining of fuel consumed by the vehicle 1, the transportation of fuel consumed by the vehicle 1, and the manufacturing of replacement parts for the vehicle 1. For example, air quality degradants emitted in conjunction with the operation of the vehicle 1, which is an electric vehicle, include air quality degradants emitted during the generation of electricity consumed by the vehicle 1, the construction of a power generation facility for the electricity consumed by the vehicle 1, and the operation of the power generation facility for the electricity consumed by the vehicle 1. For example, the air quality degradation information acquisition unit 104 acquires air quality degradation information indicating the amount of degradation in air quality at the time of the manufacture of the vehicle 1, based on the information indicating the amount of air quality degradants emitted in conjunction with the operation of the vehicle 1, acquired by the mobile object information acquisition unit 103.

[0030] Furthermore, for example, the air quality degradation information acquisition unit 104 acquires air quality degradation information indicating the amount of degradation in air quality, using a value calculated based on the amount of air quality degraders emitted by the vehicle 1 as the amount of degradation in air quality caused by the vehicle 1. Specifically, the air quality degradation information acquisition unit 104 calculates the amount of air quality degraders emitted by the vehicle 1 converted into a monetary amount, and acquires air quality degradation information indicating the amount of degradation in air quality, using the calculated amount as the amount of degradation in air quality caused by the vehicle 1. More specifically, the air quality degradation information acquisition unit 104 calculates the cost of treating the air quality degraders emitted by the vehicle 1 based on the information indicating the amount of air quality degraders emitted by the vehicle 1 and information acquired from the database 50, and acquires air quality degradation information indicating the amount of degradation in air quality, using the calculated amount as the amount of degradation in air quality caused by the vehicle 1. More specifically, the air quality degradation information acquisition unit 104 calculates the cost of treating the air quality degrading substances emitted by the vehicle 1 based on information indicating the amount of air quality degrading substances emitted by the vehicle 1 and information obtained from the database 50, such as the trading price of greenhouse gases in the carbon credit market, the cost of recovering the air quality degrading substances, the cost of recovering and treating the air quality degrading substances, and the amount of economic loss caused by the environmental load caused by the air quality degrading substances, and acquires air quality degradation information indicating the amount of air quality degradation using the calculation result as the amount of air quality degradation caused by the vehicle 1.

[0031] Also, for example, the air quality degradation information acquisition unit 104 acquires air quality degradation information indicating the amount of degradation in air quality, using the value calculated by the following formula (1) based on the amount of air quality degrading substances emitted by the vehicle 1 as the amount of degradation in air quality caused by the vehicle 1. (Decrease in air quality) W = α × A + β × B + γ × C + (1) In equation (1), A, B, C... are the amounts of each air quality degrading substance emitted by vehicle 1, and α, β, γ,... are coefficients for weighting each air quality degrading substance.

[0032] The air quality improvement information acquisition unit 105 acquires air quality improvement information indicating the amount of improvement in air quality due to the vehicle 1. For example, the air quality improvement information acquisition unit 105 acquires information indicating the performance of the air purifying device 12 from the database 50, calculates the amount of removal targets removed by the air purifying device 12 based on the information acquired from the database 50 and the information acquired by the positioning information acquisition unit 101, and acquires air quality improvement information indicating the amount of improvement in air quality due to the vehicle 1 based on the calculation result. Specifically, the air quality improvement information acquisition unit 105 acquires information indicating the amount of removal targets removed by the air purifying device 12 per unit travel distance of the vehicle 1 from the database 50, calculates the travel distance of the vehicle 1 based on the amount of removal targets removed by the air purifying device 12 per unit travel distance and the travel distance of the vehicle 1, and acquires air quality improvement information indicating the amount of improvement in air quality due to the vehicle 1 based on the calculation result. The air quality improvement information indicating the amount of improvement in air quality is not necessarily limited to a positive value, and may be a negative value depending on the function of each component. Also, in the first embodiment, the air quality improvement information indicating the amount of improvement in air quality constitutes air quality change information indicating the amount of change in air quality.

[0033] In addition, the air quality improvement information acquisition unit 105 may be configured to calculate the amount of removal targets removed by the air purifying device 12 based on information indicating the amount of air taken in by the air purifying device 12 per unit travel distance of the vehicle 1 obtained from the database 50, the detection results of the removal targets contained in the air obtained from the air quality detection device 40, and the positioning information obtained by the positioning information acquisition unit 101, or may be configured to calculate the amount of removal targets removed by the air purifying device 12 based on information indicating the amount of air taken in by the air purifying device 12 per unit travel distance of the vehicle 1 obtained from the database 50, the detection results of the removal targets contained in the air obtained from the air quality detection device 40, and information indicating the travel distance of the vehicle 1 obtained by the mobile object information acquisition unit 103.

[0034] Furthermore, for example, the air quality improvement information acquisition unit 105 calculates the amount of removal targets removed from the air taken in by the air purification device 12 mounted on the vehicle 1, converting the amount into a monetary value, and acquires air quality improvement information indicating the amount of improvement in air quality, using the calculated result as the amount of improvement in air quality due to the vehicle 1. The method of converting the amount of removal targets into a monetary value is the same as the method used by the air quality degradation information acquisition unit 104 to convert the amount of air quality degrading targets emitted by the vehicle 1 into a monetary value, and therefore a description thereof will be omitted.

[0035] Furthermore, for example, the air quality improvement information acquisition unit 105 acquires air quality improvement information indicating the amount of improvement in air quality by using the value calculated by the following formula (2) based on the amount of removal target removed from the air taken in by the air purifying device 12 installed in the vehicle 1 as the amount of improvement in air quality by the vehicle 1. (Improvement in air quality) I = α' × A' + β' × B' + γ' × C' + (2) In equation (2), A', B', C'... are the amounts of each substance to be removed removed from the air taken in by the air purifying device 12 mounted on the vehicle 1, and α', β', γ',... are coefficients for weighting each substance to be removed.

[0036] For example, in formula (1), the coefficients α, β, γ, ... are set in consideration of the magnitude of the environmental impact of each air quality degrading substance emitted by vehicle 1. Also, for example, in formula (2), the coefficients α', β', γ', ... are set in consideration of the magnitude of the environmental impact of each removal target substance removed from the air taken in by air purifying device 12 mounted on vehicle 1. Also, for example, in formula (2), for the removal target substance corresponding to the air quality degrading substance emitted by vehicle 1, the same coefficient as the coefficient in formula (1) is used.

[0037] It is also considered that the values ​​of the coefficients in formula (1) and formula (2) change the willingness of the user of vehicle 1 to act, and change the amount of improvement in local air quality. Based on this idea, for example, the coefficients α, β, γ,... and the coefficients α', β', γ',... may be set by the trained model so that the amount of improvement I in air quality becomes larger. For example, {(α1, α'1, β1, β'1, γ1, γ'1,...), (α2, α'2, β2, β'2, γ2, γ'2,...),..., (α n , α' n , β n , β' n , γ n , γ' n , ···)} and (I1, I2, I3, ···, I n ) and set the coefficients by a trained model that outputs coefficients that increase the value of the air quality improvement amount I. n The coefficient (α n , α' n , β n , β' n , γ n , γ' n , ...), the average value of the improvement in air quality over a specific period of time for multiple users. The information processing device may also include a trained model generation unit that acquires air quality improvement information from multiple users and generates the trained model based on the acquired air quality improvement information.

[0038] The reward acquisition condition information acquisition unit 106 acquires reward acquisition condition information relating to the conditions for acquiring a reward that the user of the vehicle 1 can acquire based on the use of the vehicle 1, based on information from the database 50. The user of the vehicle 1 can acquire various rewards by achieving the conditions for acquiring a reward indicated by the reward acquisition condition information. For example, the conditions for acquiring a reward indicated by the reward acquisition condition information include the amount of improvement in air quality due to the vehicle 1 being equal to or greater than a predetermined threshold, the amount of improvement in air quality due to the vehicle 1 minus the amount of decrease in air quality due to the vehicle 1 being equal to or greater than a predetermined threshold, the cumulative usage time of the air purifying device 12 being equal to or greater than a predetermined threshold, the amount of air taken in by the air purifying device 12 being equal to or greater than a predetermined threshold, etc.

[0039] Further, for example, the reward acquisition conditions indicated by the reward acquisition condition information include the vehicle 1 passing through a predetermined specific point, the vehicle 1 traveling along a predetermined specific route, the vehicle 1 traveling through a predetermined specific area, the vehicle 1 traveling on roads in a predetermined specific area at a rate equal to or greater than a predetermined threshold. In the first embodiment, the user of the vehicle 1 is a person who has the right to acquire a reward based on the use of the vehicle 1 equipped with the air purifying device 12, and may be the driver of the vehicle 1, the owner of the vehicle 1, the owner of the air purifying device 12, or any other person. The vehicle user may be a single user of multiple vehicles, a corporation, or a user of a single vehicle shared by multiple users. The reward acquisition condition information acquisition unit 106 sets reward acquisition conditions for the user of the vehicle 1 to acquire a reward based on the acquired reward acquisition condition information.

[0040] The reward acquisition determination unit 107 determines whether the user of the vehicle 1 has achieved the reward acquisition condition preset by the reward acquisition condition information acquisition unit 106, based on the details of how the vehicle 1 was used. For example, the reward acquisition determination unit 107 determines whether the preset reward acquisition condition has been achieved, based on the air quality improvement information acquired by the air quality improvement information acquisition unit 105. Also, for example, the reward acquisition determination unit 107 determines whether the preset reward acquisition condition has been achieved, based on the passing points of the vehicle 1 when it moved, which is obtained from the information from the positioning device 20. Also, for example, the reward acquisition determination unit 107 determines whether the preset reward acquisition condition has been achieved, based on the travel route of the vehicle 1, which is obtained from the information from the positioning device 20.

[0041] The reward information generation unit 108 generates reward information regarding the reward to be granted to the user of vehicle 1 based on the determination result by the reward acquisition determination unit 107. For example, the reward information generation unit 108 generates reward information indicating that the user of vehicle 1 has been granted a local currency that can be used in the area through which vehicle 1 has traveled, in accordance with the acquisition condition that has been achieved, and reward information indicating the balance with which the user of vehicle 1 can use the local currency. Furthermore, for example, the reward information generation unit 108 generates reward information indicating that the user of vehicle 1 has been granted the right to receive preferential treatment at a specific store in the area through which vehicle 1 has traveled, in accordance with the acquisition condition that has been achieved, and reward information indicating the content of the preferential treatment.

[0042] Furthermore, for example, the reward information generation unit 108 generates reward information indicating that tokens issued by a specific company, organization, local government, or national government agency have been granted to the user of vehicle 1 in accordance with the achieved acquisition conditions, and reward information indicating the balance of the tokens. Furthermore, for example, the reward information generation unit 108 generates reward information indicating that points to be used in a specific application program have been granted to the user of vehicle 1 in accordance with the achieved acquisition conditions, and reward information indicating the number of granted points. The specific application program in which the points are used is, for example, an application program for indicating the user of vehicle 1's contribution to the environment, an application program for the user of vehicle 1 to play games, etc. The reward information generation unit 108 generates reward information for deleting the reward earned by the user of vehicle 1 when the user of vehicle 1 loses ownership of the reward based on, for example, the user having consumed the earned reward or the expiration of the reward's validity period.

[0043] For example, when there are multiple users of vehicle 1, the reward information generation unit 108 generates reward information such that a reward is granted to each of the multiple users. Also, for example, when there are multiple users of vehicle 1, the reward information generation unit 108 generates reward information such that a reward is granted to one of the multiple users who was in vehicle 1 when vehicle 1 moved. Also, for example, when there are multiple users of vehicle 1, the reward information generation unit 108 generates reward information such that a reward is granted to each user according to the riding time when vehicle 1 moved.

[0044] The display control unit 109 controls the display device 60 by causing the display device 60 to display, as visual information, information indicating the results of various processes performed by the information processing device 100, information stored in the information processing device 100, and information acquired by the information processing device 100 from other devices. For example, the display control unit 109 causes the display device to display a cumulative value of the improvement in air quality due to the vehicle 1 over a specific period, based on the air quality improvement information acquired by the air quality improvement information acquisition unit 105. Specifically, the display control unit 109 causes the display device to display a cumulative value of the improvement in air quality due to the vehicle 1 over a period from when the air purifying device 12 was installed in the vehicle body 11 of the vehicle 1 to the present, based on the air quality improvement information acquired by the air quality improvement information acquisition unit 105.

[0045] Furthermore, for example, the display control unit 109 causes the display device 60 to display the cumulative values ​​of the improvement and decrease in air quality caused by the vehicle 1 during a specific period, based on the air quality improvement information acquired by the air quality improvement information acquisition unit 105 and the air quality decrease information acquired by the air quality decrease information acquisition unit 104. Specifically, the display control unit 109 causes the display device 60 to display the cumulative value of the improvement in air quality caused by the vehicle 1 during a specific period and the cumulative value of the decrease in air quality caused by the vehicle 1 during a specific period, in a manner that allows them to be compared with each other, based on the air quality improvement information acquired by the air quality improvement information acquisition unit 105 and the air quality decrease information acquired by the air quality decrease information acquisition unit 104. More specifically, based on the air quality improvement information acquired by the air quality improvement information acquisition unit 105 and the air quality degradation information acquired by the air quality degradation information acquisition unit 104, the display control unit 109 displays on the display device 60 the cumulative value of the improvement in air quality due to vehicle 1 during the period from the completion of vehicle 1 to the present and the cumulative value of the degradation in air quality due to vehicle 1 during the period from the time of material production of vehicle 1 to the present in a manner that allows them to be compared with each other.

[0046] Specifically, the display control unit 109 causes the display device 60 to display a value obtained by subtracting the cumulative amount of air quality degradation caused by the vehicle 1 during a specific period from the cumulative amount of improvement in air quality caused by the vehicle 1 during that specific period, as the cumulative values ​​of the amount of improvement and amount of degradation in air quality caused by the vehicle 1 during that specific period, based on the air quality improvement information acquired by the air quality improvement information acquisition unit 105 and the air quality degradation information acquired by the air quality degradation information acquisition unit 104. More specifically, the display control unit 109 causes the display device 60 to display a value obtained by subtracting the cumulative amount of degradation in air quality caused by the vehicle 1 during the period from the time of material production of the vehicle 1 to the present from the cumulative value of the amount of improvement in air quality caused by the vehicle 1 during the period from the completion of the vehicle 1 to the present, based on the air quality improvement information acquired by the air quality improvement information acquisition unit 105 and the air quality degradation information acquired by the air quality degradation information acquisition unit 104. The display control unit 109 may be configured to display the cumulative values ​​of the improvement and decrease in air quality on the display device 60 as text, or as a pie chart, a bar graph, or in other formats. The display control unit 109 may be configured to display only one of the cumulative value of the improvement in air quality, the cumulative value of the decrease in air quality, and the value obtained by subtracting the cumulative value of the decrease in air quality from the cumulative value of the improvement in air quality on the display device 60, or may be configured to display multiple of these values. The cumulative value of the improvement in air quality, the cumulative value of the decrease in air quality, and the value obtained by subtracting the cumulative value of the decrease in air quality from the cumulative value of the improvement in air quality are all information related to the cumulative value of the amount of change in air quality caused by the vehicle 1.

[0047] Furthermore, for example, the display control unit 109 causes the display device 60 to display map information acquired by the map information acquisition unit 102. Specifically, the display control unit 109 causes the display device 60 to display an image showing a map of the periphery of the vehicle 1 and an image showing the position of the vehicle 1 on the map, based on the map information acquired by the map information acquisition unit 102 and the positioning information acquired by the positioning information acquisition unit 101. Specifically, the display control unit 109 causes the display device 60 to display an image showing a map of the periphery of the vehicle 1 and an image showing the travel route traveled by the vehicle 1, based on the map information acquired by the map information acquisition unit 102 and the positioning information acquired by the positioning information acquisition unit 101.

[0048] Specifically, the display control unit 109 causes the display device 60 to display an image showing a map of the area where the vehicle 1 is located and an image showing an area where the air quality has been improved by the vehicle 1, based on the map information acquired by the map information acquisition unit 102, the positioning information acquired by the positioning information acquisition unit 101, and the air quality improvement information acquired by the air quality improvement information acquisition unit 105. Specifically, the display control unit 109 causes the display device 60 to display an image showing a map of the area where the vehicle 1 is located and an image showing an area where the air quality has been improved by the vehicle 1, based on the map information acquired by the map information acquisition unit 102, the positioning information acquired by the positioning information acquisition unit 101, and the air quality improvement information acquired by the air quality improvement information acquisition unit 105.

[0049] More specifically, the display control unit 109 causes the display device 60 to display an image showing a map of the area where the vehicle 1 is located and an image showing the range in which the air quality has been improved by the vehicle 1, based on the map information acquired by the map information acquisition unit 102, the travel route of the vehicle 1 obtained from the positioning information acquired by the positioning information acquisition unit 101, and the amount of improvement in air quality per unit travel distance of the vehicle 1 obtained based on the air quality improvement information acquired by the air quality improvement information acquisition unit 105. Note that the information processing device 100 may be configured to acquire information showing the amount of improvement in air quality per unit travel distance of the vehicle 1 based on information showing the performance of the air purifying device 12 stored in the database 50, or may be configured to acquire information showing the amount of improvement in air quality per unit travel distance of the vehicle 1 based on information showing the performance of the air purifying device 12 stored in the database 50 and information acquired from the air quality detection device 40.

[0050] Specifically, the display control unit 109 controls the display device 60 to display an image showing a map of the area where the vehicle 1 is located and an image showing an area where air quality has been improved by the vehicle 1, the image showing an area where air quality has been improved over time, based on the map information acquired by the map information acquisition unit 102, the positioning information acquired by the positioning information acquisition unit 101, and the air quality improvement information acquired by the air quality improvement information acquisition unit 105. For example, the area where air quality has been improved by the vehicle 1, which changes over time, can be calculated by a simulation based on the elapsed time since the vehicle 1 passed, which is obtained from the positioning information of the vehicle 1. The display control unit 109 may also be configured to calculate, by a simulation, the concentration of air quality degraders, which changes over time, in the area where air quality has been improved by the vehicle 1, and to display an image showing the calculation result on the display device 60. The display control unit 109 may also be configured to display, on the display device 60, an image that visualizes the concentration of air quality degraders in the air in the area, based on the detection result of the substances to be removed by the air quality detection device 40 installed in the area where the vehicle 1 travels.

[0051] Furthermore, for example, the display control unit 109 causes the display device 60 to display information regarding the reward that the user of the vehicle 1 can earn based on the use of the vehicle 1, based on the reward earning condition information acquired by the reward earning condition information acquisition unit 106, the result of the determination by the reward earning determination unit 107, and the reward information generated by the reward information generation unit 108. Specifically, the display control unit 109 causes the display device 60 to display information indicating the degree of achievement of the reward earning condition and information indicating the content of the reward that the user of the vehicle 1 can earn by achieving the reward earning condition, based on the reward earning condition information acquired by the reward earning condition information acquisition unit 106 and the air quality improvement information acquired by the air quality improvement information acquisition unit 105. Note that both the information indicating the degree of achievement of the reward earning condition and the information indicating the content of the reward that the user of the vehicle 1 can earn by achieving the reward earning condition are information generated based on the cumulative value of the amount of change in air quality caused by the vehicle 1, and therefore, are information regarding the cumulative value of the amount of change in air quality caused by the vehicle 1.

[0052] Furthermore, specifically, the display control unit 109 causes the display device 60 to display information indicating that the user of vehicle 1 has fulfilled the reward earning conditions, based on the reward earning condition information acquired by the reward earning condition information acquisition unit 106 and the air quality improvement information acquired by the air quality improvement information acquisition unit 105. Furthermore, specifically, the display control unit 109 causes the display device 60 to display information indicating that the user of vehicle 1 has earned a reward and information indicating the content of the earned reward, based on the reward information generated by the reward information generation unit 108. For example, the display control unit 109 causes the display device 60 to display information such as a number, barcode, or two-dimensional code indicating the tokens earned by the user of vehicle 1, as information indicating the content of the reward earned by the user of vehicle 1. Furthermore, for example, the display control unit 109 causes the display device 60 to display the accumulated value of points earned by the user of vehicle 1, as information indicating the content of the reward earned by the user of vehicle 1. Furthermore, for example, the display control unit 109 causes the display device 60 to display an image indicating the degree of contribution made by the user of the vehicle 1 to the environment, as information indicating the content of the reward acquired by the user of the vehicle 1.

[0053] The display control unit 109 may also be configured to work in conjunction with a car navigation system (not shown) included in the vehicle 1 to suggest a travel route for the vehicle 1 based on the reward acquisition condition information acquired by the reward acquisition condition information acquisition unit 106. For example, the display control unit 109 may be configured to select, from multiple travel routes for the vehicle 1 calculated by the car navigation system, a route that will result in the largest reward being acquired by the user of the vehicle 1, and present the selected travel route to the user via the car navigation system. The display control unit 109 may also be configured to work in conjunction with a car navigation system (not shown) included in the vehicle 1 to suggest a travel route for the vehicle 1 based on information from air quality detection devices 40 installed in the area. For example, the display control unit 109 may be configured to select, from multiple travel routes for the vehicle 1 calculated by the car navigation system, a route that will result in the largest improvement in air quality due to the vehicle 1, and present the selected travel route to the user via the car navigation system.

[0054] Next, the hardware configuration of the information processing device 100 will be described with reference to Figures 3 and 4. Figure 3 is a diagram showing an example of the hardware configuration of the information processing device 100, and Figure 4 is a diagram showing an example of the hardware configuration of the information processing device 100 that is different from that shown in Figure 3. For example, as shown in Figure 3, the information processing device 100 is a computer having a processor 100a, a memory 100b, and an I / O port 100c, and is configured so that the processor 100a reads and executes a program stored in the memory 100b.

[0055] 4, the information processing device 100 is a computer that has a processing circuit 100d, which is dedicated hardware, and an I / O port 100c, and executes a program. The processing circuit 100d is configured, for example, by a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof. Each function of the information processing device 100 is realized by the processor 100a or the processing circuit 100d, which is dedicated hardware, executing a program. Note that the information processing device 100 may also have hardware other than those described above, such as a hardware timer.

[0056] Next, details of the processing performed by the information processing device 100 will be described with reference to Fig. 1, Fig. 2, Fig. 5, and Fig. 6. Fig. 5 is a flowchart showing an example of the processing performed by the information processing device 100 according to the first embodiment. As shown in Fig. 5, when the information processing device 100 starts the processing, it first acquires positioning information (step ST01). In this processing, the information processing device 100 acquires positioning information indicating the latitude and longitude at which the vehicle is located based on information from the positioning device 20, for example, at predetermined time intervals.

[0057] After performing the process of step ST01, the information processing device 100 acquires map information (step ST02). In this process, the information processing device 100 acquires, for example, map information indicating a map of the area around the position of the vehicle 1 indicated by the positioning information acquired in step ST01.

[0058] After performing the process of step ST02, the information processing device 100 acquires mobile object information (step ST03). In this process, the information processing device 100 acquires, for example, mobile object information indicating the amount of energy consumption of the vehicle 1 since the last time the mobile object information was acquired. Note that in this process, the information processing device 100 may be configured to acquire mobile object information indicating the cumulative value of the amount of energy consumption of the vehicle 1 over a specific period of time.

[0059] After performing the process of step ST03, the information processing device 100 acquires air quality degradation information (step ST04). In this process, the information processing device 100 acquires, for example, air quality degradation information indicating the amount of degradation in air quality caused by the vehicle 1 since the last time the information on degradation in air quality was acquired. Note that in this process, the information processing device 100 may be configured to acquire air quality degradation information indicating the cumulative value of the amount of degradation in air quality caused by the vehicle 1 over a specific period of time.

[0060] After performing the process of step ST04, the information processing device 100 acquires air quality improvement information (step ST05). In this process, the information processing device 100 acquires, for example, air quality improvement information indicating the amount of improvement in air quality due to the vehicle 1 since the last time the information on air quality improvement was acquired. Note that in this process, the information processing device 100 may be configured to acquire air quality improvement information indicating the cumulative value of the amount of improvement in air quality due to the vehicle 1 over a specific period of time.

[0061] After performing the process of step ST05, the information processing device 100 acquires reward acquisition condition information (step ST06). In this process, the information processing device 100 acquires the latest reward acquisition condition information based on information from the database 50. Note that if the update frequency of the reward acquisition condition is sufficiently lower than the frequency at which the positioning information acquisition unit 101 acquires the positioning information, the information processing device 100 may be configured to perform the process of step ST06 less frequently than the processes other than step ST06 among the processes of steps ST01 to ST09.

[0062] After performing the process of step ST06, the information processing device 100 determines whether or not the reward acquisition condition has been met (step ST07). In this process, the information processing device 100 determines whether or not the user of the vehicle 1 has met a new reward acquisition condition for which a reward has not yet been granted, based on the reward acquisition condition information acquired last.

[0063] In the process of step ST07, if the reward acquisition condition is met (YES in step ST07), the information processing device 100 generates reward information (step ST08). In this process, the information processing device 100 generates reward information regarding a reward according to the achieved reward acquisition condition, based on the fact that the user of the vehicle 1 has achieved a new reward acquisition condition.

[0064] If the reward acquisition condition is not met in the processing of step ST07 (NO in step ST07), and if the processing of step ST08 is performed, the information processing device 100 causes the display device 60 to display an image (step ST09). If the processing of step ST08 is performed, the information processing device 100 causes the display device 60 to display, for example, an image showing the content of the acquired reward, an image showing a map of the surroundings of the vehicle 1, an image showing the position of the vehicle 1 on the map, an image showing the range in which air quality has been improved by the vehicle 1, and the cumulative values ​​of the improvement and decrease in air quality due to the vehicle 1. Furthermore, if the reward acquisition condition is not met in the processing of step ST07, the information processing device 100 causes the display device 60 to display, for example, an image showing a map of the surroundings of the vehicle 1, an image showing the position of the vehicle 1 on the map, an image showing the range in which air quality has been improved by the vehicle 1, and the cumulative values ​​of the improvement and decrease in air quality due to the vehicle 1.

[0065] In addition, the information processing device 100 may be configured to display an image indicating the degree of fulfillment of the reward acquisition condition if the reward acquisition condition is not fulfilled in the processing of step ST07, or may be configured to display an image indicating the degree of fulfillment of the reward acquisition condition in response to an input operation by the user of the vehicle 1 on an input device (not shown) performed at any time.

[0066] FIG. 6 is a diagram illustrating an example of an image that the information processing device 100 according to the first embodiment displays on the display device 60. As illustrated in FIG. 6, for example, the information processing device 100 causes the display device 60 to display a map of the area around the vehicle 1, an image indicating the position of the vehicle 1 on the map, an image indicating a travel path P1 of the vehicle 1, and an image indicating an area K1 in which air quality has been improved by the vehicle 1. The information processing device 100 also causes the display device 60 to display, for example, images indicating specific points T1 and T2 related to a condition for receiving a reward. For example, point T1 is located on a road near a school S1, and indicates that a local government in that area has set a condition for the user of the vehicle 1 that the vehicle 1 passes through point T1 as a condition for receiving a reward. For example, point T2 is located on a road near a hospital S2, and indicates that the hospital has set a condition for the user of the vehicle 1 that the vehicle 1 passes through point T2 as a condition for receiving a reward.

[0067] Furthermore, for example, the information processing device 100 displays an image indicating an area K2 related to a condition for obtaining a reward on the display device 60. The area K2 is an area set around the factory S3, and indicates that the factory S3 has set a condition for the user of the vehicle 1 that the vehicle 1 must pass through the area K2 to obtain a reward. The database 50 updates the stored contents of the reward obtaining condition information and the reward information related to the condition for obtaining a reward based on input information from a specific store, specific company, organization, local government, national government agency, etc. that sets the condition for obtaining a reward for the user of the vehicle 1. For example, the stored contents of the reward obtaining condition information and the reward information related to the condition for obtaining a reward are updated based on input information from a local government indicating areas where the local government in the area where the vehicle 1 travels has set a condition for the vehicle 1 to pass through as a condition for obtaining a reward, such as areas where the local government particularly requires improvement in air quality, such as areas with low air quality, areas near tourist facilities, areas near sports facilities, areas near parks, areas near childcare facilities, areas near nursing homes, areas near educational facilities, areas near medical facilities, and areas prone to traffic congestion due to vehicles.

[0068] As described above, the information processing device 100 according to the first embodiment includes the air quality improvement information acquisition unit 105 that acquires air quality improvement information indicating the amount of improvement in air quality due to the vehicle 1 equipped with the air purifying device 12, and the display control unit 109 that causes the display device 60 to display the cumulative value of the amount of improvement in air quality due to the vehicle 1 over a specific period, based on the air quality improvement information acquired by the air quality improvement information acquisition unit 105. With this configuration, the information processing device 100 can know the extent to which the user of the vehicle 1 equipped with the air purifying device 12 has contributed to improving air quality. Furthermore, by knowing the extent to which the user of the vehicle 1 has contributed to improving air quality, the user's motivation to take action to improve local air quality can be increased, thereby improving local air quality.

[0069] Furthermore, the information processing device 100 according to the first embodiment includes an air quality degradation information acquisition unit 104 that acquires air quality degradation information indicating the amount of degradation in air quality caused by the vehicle 1, and the display control unit 109 is configured to cause the display device 60 to display the cumulative values ​​of the improvement and degradation in air quality caused by the vehicle 1 over a specific period, based on the air quality improvement information acquired by the air quality improvement information acquisition unit 105 and the air quality degradation information acquired by the air quality degradation information acquisition unit 104. With this configuration, the information processing device 100 causes the display device 60 to display the cumulative values ​​of the improvement and degradation in air quality caused by the vehicle 1, thereby enabling the user of the vehicle 1 to know the impact on air quality, including the amount of degradation in air quality caused by the vehicle 1. This helps the user understand the degree to which the user's use of the vehicle 1 contributes to improving local air quality, and increases the user's motivation to take action to improve local air quality, thereby enabling the improvement of local air quality.

[0070] Furthermore, the information processing device 100 according to the first embodiment includes a positioning information acquisition unit that acquires positioning information of the vehicle 1 and a map information acquisition unit that acquires map information including a travel route, and the display control unit is configured to cause the display device to display an area on a map where air quality has been improved by the movement of the vehicle 1, based on the air quality improvement information acquired by the air quality improvement information acquisition unit, the positioning information acquired by the positioning information acquisition unit, and the map information acquired by the map information acquisition unit. With this configuration, the information processing device 100 visualizes the degree of contribution of the user to improvement of local air quality through use of the vehicle 1, thereby increasing the user's motivation to take action to improve local air quality, and thereby enabling the improvement of local air quality.

[0071] Furthermore, the information processing device 100 according to the first embodiment includes a reward acquisition determination unit that determines whether a preset reward acquisition condition has been achieved based on the details of how the vehicle 1 is used, and a reward information generation unit that generates reward information regarding a reward to be granted to the user of the vehicle 1 based on the determination result by the reward acquisition determination unit. With this configuration, the information processing device 100 can increase the user's motivation to take action to improve local air quality, thereby improving local air quality.

[0072] Note that, although the information processing device 100 according to the first embodiment is configured to acquire air quality improvement information indicating the amount of improvement in air quality due to the vehicle 1 equipped with the air purifying device 12, the present invention is not limited to this. The information processing device only needs to be configured to acquire air quality improvement information indicating the amount of improvement in air quality due to a mobile body equipped with an air purifying device, and for example, the mobile body may be an unmanned vehicle, a railway vehicle, an aircraft, a construction vehicle, an agricultural vehicle, a drone, a light vehicle without a motor, or any other mobile body equipped with an air purifying device.

[0073] Furthermore, the display device 60 on which the information processing device 100 according to the first embodiment displays information is not limited to one provided in the vehicle 1. The display device on which the information processing device displays information may be one that can be viewed by the user of the vehicle 1, and for example, the display device may be a monitor of a computer that functions independently of the vehicle 1 and is used by the user of the vehicle 1, or may be a mobile terminal such as a smartphone or tablet terminal that is used by the user of the vehicle 1.

[0074] The information processing device 100 may be provided outside the vehicle 1, or may include some or all of the other components of the information processing system, or some of the components may be provided in another device that is communicatively connected to the information processing device, or may be communicatively connected to the other components of the information processing system via other devices, computers, or communication networks not shown. Furthermore, in the first embodiment, the display control unit 109 is configured to cause the display device 60 to display the cumulative value of the improvement in air quality due to the vehicle 1 over a specific period of time, based on the air quality improvement information acquired by the air quality improvement information acquisition unit 105. However, this is not limiting. The display control unit may be configured to cause the display device 60 to display air quality-related information, which is information regarding the change in air quality due to the vehicle 1 over a specific period of time, based on air quality change information consisting of either or both of air quality deterioration information and air quality improvement information acquired by an air quality change information acquisition unit including at least one of the air quality deterioration information acquisition unit 104 and the air quality improvement information acquisition unit 105. For example, the display control unit may be configured to cause the display device 60 to display only one or both of reward information regarding a reward to be granted to the user and an image showing an area on a map where air quality has been improved by the vehicle 1, based on the air quality change information acquired by the air quality change information acquisition unit.
