≪Configuration of CO ₂ capture device≫
As shown in FIG. 2, the CO ₂ capture device 20 includes a CO ₂ capture unit 21, a suction pump 22, and a cooling unit 23.

As shown in FIG. 2, the CO ₂ capture unit 21 communicates with the exhaust pipe 12 via the communication passage 24. A cooling unit 23 is provided in the communication passage 24. Further, the CO ₂ capture unit 21 leads to the outside of the vehicle via the discharge passage 25. A suction pump 22 is provided in the discharge passage 25. Further, the CO ₂ capture unit 21 is communicated with the CO ₂ recovery port 26a via the recovery passage 26.

The CO ₂ capture unit 21 is a device that captures _{CO 2 in the gas supplied to the CO 2} capture unit 21 (in the present embodiment, the exhaust gas discharged from the internal combustion engine 10). In the present embodiment, the CO ₂ capture unit 21 is arranged in or below the luggage space located behind the vehicle 1. Since the CO ₂ capture device 20 is a heavy object, it is desirable to arrange it downward in the vertical direction as much as possible in the luggage space.

_{Examples of the method for capturing CO 2 in} the gas by the CO ₂ capturing unit 21 include a physical adsorption method, a physical absorption method, a chemical absorption method, and a deep cold separation method.

Physical adsorption method, for example including a solid adsorbent and CO _2, such as activated carbon or zeolite by contacting the gas adsorbing the CO ₂ to the solid adsorbent, CO from the solid adsorbent by heating (or reduced pressure) _This is a method of desorbing and collecting 2.

When the physical adsorption method is adopted, the CO ₂ capture unit 21 is configured as, for example, a container containing pelletized zeolite. _{CO 2} is adsorbed on the zeolite by circulating a gas containing _{CO 2} in this container.

In the physical absorption method, _{an absorption liquid capable of dissolving CO 2} (for example, methanol or N-methyl hiroridone) is brought into contact with a gas containing _{CO 2} to physically absorb _{CO 2 under high pressure and low temperature.} This is a method of recovering _{CO 2} from the absorption liquid by absorbing it into an absorbent solution and heating (or reducing the pressure).

When the physical absorption method is adopted, the CO ₂ capture unit 21 is configured as, for example, a container containing methanol. _{CO 2} is absorbed by methanol by flowing a gas containing _{CO 2} into the methanol contained in this container.

Chemical absorption method, the absorption absorbing solution capable of selectively dissolving the CO ₂ (for example, an amine, potassium carbonate solution) the CO ₂ by a chemical reaction by contacting a gas containing the CO ₂ absorption liquid This is a method of dissociating and recovering carbon dioxide from the absorption liquid by heating the mixture.

When the chemical absorption method is adopted, the CO ₂ capture unit 21 is configured as, for example, a container containing an amine. _{CO 2} is absorbed by methanol by flowing a gas containing _{CO 2} into the methanol contained in this container.

In the present embodiment, the CO ₂ capture unit 21 uses a method that employs a physical adsorption method as a method for recovering _{CO 2 in the exhaust gas.} Therefore, the CO ₂ capture unit 21 is configured as a container containing pelletized zeolite.

The suction pump 22 is provided in the discharge passage 25 communicating with _{the CO 2 capture unit 21.} The suction pump 22 is arranged on the downstream side _{of the CO 2} capture unit 21 in the flow direction of the exhaust gas.

The suction pump 22 is _{configured to suck gas from the CO 2} capture unit 21 and discharge it into the atmosphere. In other words, the suction pump 22 is configured to forcibly send gas _{from the exhaust pipe 12 to the CO 2 capture unit 21 via the communication passage 24.} Further, the suction pump 22 is configured so that its output can be changed. As the output of the suction pump 22 increases, the flow rate of gas flowing through the _{CO 2 capture unit 21 increases.}

The cooling unit 23 is provided in the communication passage 24 and cools the exhaust gas flowing in the communication passage 24. The cooling unit 23 communicates with the CO ₂ capture unit 21 via the communication passage 24. Therefore, the gas cooled in the cooling unit 23 flows into the _{CO 2 capturing unit 21 through the communication passage 24.} In other words, the cooling unit 23 is arranged on the upstream side _{of the CO 2 capturing unit 21 in the flow direction of the exhaust gas.}

The cooling unit 23 is configured as a refrigeration circuit including, for example, a compressor, a condenser, an expansion valve, and an evaporator. In the cooling unit 23, the refrigeration cycle is realized by circulating the refrigerant through these components. In particular, the evaporator cools the exhaust gas by directly exchanging heat with the exhaust gas flowing through the communication passage 24 or indirectly through the medium. Since the refrigerant in the refrigeration circuit drops to a temperature lower than the temperature of the atmosphere, in the present embodiment, the cooling unit 23 sets the temperature of the exhaust gas flowing into the cooling unit 23 to a temperature lower than the temperature of the atmosphere (normal temperature). Can be reduced to.

The cooling unit 23 does not necessarily have to be configured as a refrigeration circuit. The cooling unit 23 may be configured in any way as long as it can cool the exhaust gas flowing through the communication passage 24. Therefore, for example, the cooling unit 23 may be provided with the radiator of the vehicle 1 and may be configured to cool the exhaust gas flowing through the communication passage 24 by the cooling liquid cooled by the radiator. The cooling unit 23 may be configured to be arranged around the CO ₂ capture unit 21 for cooling the CO ₂ capture unit 21.

Further, the CO ₂ capture device 20 includes various sensors. Specifically, as shown in FIG. 2, the CO ₂ capture device 20 includes a CO ₂ concentration sensor 51, a flow rate sensor 52, and a temperature sensor 53.

CO ₂ concentration sensor 51, than CO ₂ capture unit 21 is provided in the communication passage 24 of the exhaust gas flow upstream side, detects the CO ₂ concentration of the gas flowing into the CO ₂ capture unit 21. Flow sensor 52, than CO ₂ capture unit 21 is provided in the communication passage 24 of the exhaust gas flow upstream side, to detect the flow rate of the gas flowing into the CO ₂ capture unit 21. The temperature sensor 53 detects the temperature of the _{CO 2 capture unit 21.}

Be prepared. The input port and output port of the ECU 30 are connected to various actuators, various sensors, and the like of the internal combustion engine 10. Output signals from various sensors and the like are input to the input port of the ECU 30. In addition, the output port of the ECU 30 outputs _{control signals to various actuators of the internal combustion engine 10, the CO 2} capture device 20, the HMI 40, and the like. Therefore, the various actuators of the internal combustion engine 10, the CO ₂ capture device 20, and the HMI 40 are controlled by the ECU 30.

As shown in FIG. 2, the ECU 30 is connected to various sensors. Specifically, the ECU 30 is connected to the positioning sensor 50, the CO ₂ concentration sensor 51, the flow rate sensor 52, and the temperature sensor 53, and the output values of these sensors are input.

FIG. 3 is a functional block diagram of the ECU 30. As shown in FIG. 3, in the present embodiment, the ECU 30 includes a CO ₂ capture control unit 31 and a display control unit 32 as functional modules. _{In the present embodiment, the ECU 30 functions as a CO 2} capture control unit 31 and a display control unit 32 by executing a program or the like stored in the memory.

The CO ₂ capture control unit 31 executes general control in the _{CO 2 capture device 20.} For example, the CO ₂ capture control unit 31 can control the discharge capacity and the stop of suction in the suction pump 22, the cooling temperature and the stop of cooling in the cooling unit 23, and the like.

The display control unit 32 executes general control in the HMI 40. The information display device according to the present embodiment is configured by the display control unit 32 and the HMI 40. As shown in FIG. 3, the display control unit 32 includes an acquisition unit 33 and a display unit 34. Acquisition unit 33 acquires facility information including the CO ₂ recovery condition in the position information and the CO ₂ recovery facility 2 of the CO ₂ recovery facility 2 from an external server 5. Further, the acquisition unit 33 acquires the position information of the vehicle 1 from the positioning sensor 50. The display unit 34 creates a navigation map based on the position information of the vehicle 1 acquired from the positioning sensor 50, the facility information described later, and the like, and displays the created navigation map via the HMI 40.

≪Composition of HMI≫
The HMI 40 is an interface for inputting / outputting information between the user and the ECU 30. The HMI 40 includes, for example, a display for displaying character information and image information, an operation button or a touch panel for the user to perform an input operation, and the like. In the present embodiment, for example, the navigation map and the _{amount of CO 2} captured by the _{CO 2} capture device 20 are displayed via the HMI 40.

≪Overview of positioning sensor≫
The positioning sensor 50 generates position information indicating the current location of the vehicle 1. The position information generated by the positioning sensor 50 is output to the ECU 30. The positioning sensor 50 is, for example, a GPS (Global Positioning System) of a car navigation system installed in the vehicle 1.

≪Overview of CO ₂ capture method≫
Hereinafter, a method of capturing _{CO 2 in the CO 2} capture device 20 will be described. In the CO ₂ capture device 20 described above, when the suction pump 22 is operated, a part of the exhaust gas flowing through the exhaust pipe 12 flows through the communication passage 24. Even if the suction pump 22 is not operated, if the amount is small, the exhaust gas will flow through the communication passage 24. The exhaust gas flowing through the communication passage 24 flows into the cooling unit 23. Further, among the exhaust gas flowing through the exhaust pipe 12, the exhaust gas that has not flowed into the communication passage 24 flows through the exhaust pipe 12 as it is and is released to the atmosphere.

When the exhaust gas discharged from the internal combustion engine 10 is at a high temperature, the cooling unit 23 is activated so that the exhaust gas is targeted by the cooling unit 23 before flowing into the _{CO 2 capturing unit 21 in the communication passage 24.} It is cooled to the cooling temperature. _{For example, when zeolite is used as the CO 2 adsorbent of the CO 2} capture unit 21 as in the present embodiment, the exhaust gas flowing through the communication passage 24 is _{the CO 2 of the zeolite in the CO 2} capture unit 21 in the cooling unit 23. It is cooled to a cooling temperature below room temperature (for example, about 30 ° C.) so as to optimize the capture capacity of carbon dioxide. Therefore, low-temperature exhaust gas is allowed to flow into _{the CO 2 capture unit 21.}

When the exhaust gas cooled in the cooling unit 23 flows into the CO ₂ capture unit 21 flows through the communication passage 24, the exhaust gas flowing with CO ₂ adsorbent of CO ₂ capture unit 21 is in contact. As a result, the CO ₂ capture unit 21, CO ₂ is adsorbed and removed from the exhaust gas.

_{The exhaust gas after CO 2} is adsorbed and removed by the CO ₂ capture unit 21 flows through the discharge passage 25 and is released to the atmosphere.

≪Overview of CO ₂ recovery method≫
CO ₂ captured in CO ₂ capture device 20, the vehicle 1 equipped with CO ₂ capture device 20 when visiting the CO ₂ recovery facility 2, is recovered by using the CO ₂ recovery facility 4. As described above, when CO _{2 is recovered by a physical adsorption method using zeolite, CO 2} can be desorbed from the zeolite by heating or reducing the pressure of the zeolite. Therefore, the heating of the CO ₂ adsorbent of the CO ₂ recovery facility 2, CO ₂ capture unit 21 is performed.

Moreover, upon recovering CO ₂ in the CO ₂ recovery facility 2, specifically, first, the hose 4a of the CO ₂ recovery facility 4 is connected to the CO ₂ recovery port 26a. After that, _{the CO 2 adsorbent of the CO 2} capture unit 21 is heated. The heating of the CO ₂ adsorbent is performed, for example, by allowing high-temperature exhaust gas to flow into the _{CO 2 capture unit 21 from the exhaust pipe 12 without operating the cooling unit 23.} Alternatively, the heating of the CO ₂ adsorbent may be effected by heating the CO ₂ capture unit 21 by the heater disposed outside of the heater around the CO ₂ capture unit 21. Then, _{at the same time as heating the CO 2} adsorbent, suction is performed using the hose 4a. As a result, the CO ₂ from the CO ₂ adsorbent of CO ₂ capture unit 21 is released, it desorbed CO ₂ is collected in the storage tank 4b through the return passage 26 and hose 4a. At this time, the user of the vehicle 1, for example to give like selling CO ₂ trapped in the CO ₂ recovery facility 2 in CO ₂ capture device 20, an amount corresponding to the recovery of CO ₂ from the CO ₂ recovery facility 2 May be good.

Display and the actions and effects »of recoverable CO ₂ recovery facility «CO ₂
By the way, the user of the vehicle 1 _{often does not know which facility the CO 2} recovery facility 4 is installed in. Therefore, even when the _{amount of CO 2 captured by the CO 2} capture device 20 is sufficiently large and the CO ₂ capture facility 2 is present _{near the user's vehicle 1, the user captures the CO 2} by the CO 2 capture device 20. in some cases in order to recover the CO ₂ which is not directed to the CO ₂ recovery facility 2. As a result, for example, even if the CO ₂ capture device 20 _{cannot capture CO 2} any more, the user continues to operate as it is, resulting in deterioration of the _{CO 2 recovery efficiency.}

On the other hand, in the present embodiment, the display unit 34 displays the CO ₂ recovery facility 2 on the navigation map based on the facility information described later acquired from the server 5. As a result, the user can grasp the position of the _{CO 2 recovery facility 2.} Therefore, for example, when the trapping amount of CO ₂ in the CO ₂ capture system 20 of the vehicle 1 becomes sufficiently large, CO users vehicle 1, which is captured by the CO ₂ recovery facility 2 to CO ₂ capture device 20 ₂ can be directed to the CO ₂ recovery facility 2 in order to recover. As a result, for example, even if the CO ₂ capture device 20 cannot capture _{CO 2 any more, it is suppressed that CO 2} is not recovered, so that _{the deterioration of the CO 2} recovery efficiency is suppressed.

On the other hand, when the user _{collects CO 2} captured by the _{CO 2} capture device 20 at the CO ₂ recovery facility 2, the CO ₂ recovery facility 2 does not want to recover _{the CO 2} depending on the conditions of the vehicle 1. There is. For example, when CO ₂ trapped in CO ₂ capture system 20 of the vehicle 1 is too small, CO ₂ recovery facility 2 is considered not to perform the recovery of CO _2. In such case, even if the user went to the CO ₂ recovery facility 2, CO ₂ trapped in the CO ₂ capture unit 20 it is not recovered. As a result, since in order to recover the CO ₂ trapped in the CO ₂ capture unit 20, there is a user need is directed to a different CO ₂ recovery facility 2 that look for another CO ₂ recovery facility 2, CO ₂ This has led to deterioration of recovery efficiency and fuel efficiency.

Therefore, in the present embodiment, the display unit 34 sets the _{CO 2} recovery facility 2 that _{satisfies the CO 2} recovery condition described later by the vehicle 1 as a facility that recovers _{CO 2 on the navigation map based on the facility information described later.} indicate. As a result, the user, in addition to the location of the CO ₂ recovery facility 2 may be the CO ₂ recovery facility 2 to grasp that the CO ₂ can be recovered. Therefore, it is suppressed that the CO _{2 captured by the CO 2 capture device 20 cannot be recovered, so that the deterioration of the CO 2} recovery efficiency and the deterioration of the fuel consumption are suppressed.

≪Flowchart≫
FIG. 4 is a flowchart showing a control routine in the ECU 30 according to the present embodiment. The illustrated control routine is executed at regular time intervals.

In step S11, the facility information including the CO ₂ recovery condition in the position information and the CO ₂ recovery facility 2 for the CO ₂ recovery facility 2 is acquired from an external server 5. For example, the ECU 30 is a facility that requests facility information regarding _{each CO 2} recovery facility 2 in response to the detection that the vehicle 1 has entered another area from one area based on the output signal of the positioning sensor 50. The information request is transmitted to the server 5. _{In the present embodiment, the server 5 transmits the facility information about each CO 2} recovery facility 2 to the ECU 30 in response to receiving the facility information request from the ECU 30. The ECU 30 receives the facility information of _{each CO 2} recovery facility 2 transmitted from the server 5. In step S11, for example, the ECU 30 may periodically receive facility information about _{each CO 2 recovery facility 2 from the server 5.}

Here, the CO ₂ recovery conditions in each CO ₂ recovery facility 2, for example, the necessity of the CO ₂ recovery from each vehicle, CO ₂ capture device captures the amount of the lower limit of the CO ₂ in 20, the CO ₂ recovery facility 2 times can correspond to the recovery of CO _2, CO ₂ recovery facility CO ₂ per unit gram of 2 recovery rate (hereinafter, simply referred to as "recovery rate") includes one or more conditions such as. For example, in this embodiment, the CO ₂ recovery facility 2 administrator, via the client computer 3, to set the CO ₂ recovery conditions suitable for the CO ₂ recovery facility 2. The client computer 3 of the CO ₂ recovery facility 2, for example, in response to the CO ₂ recovery conditions are set by the administrator of the CO ₂ recovery facility 2, and transmits the set CO ₂ recovery condition to the server 5 .. However, _{the client computer 3 of the CO 2 recovery facility 2 may transmit the CO 2} recovery condition to the server 5 in response to a request from the server 5, for example. The CO ₂ recovery conditions are not limited to those described above, and are appropriately set according to the purpose and the like. After step S11, the control routine proceeds to step S12.

In step S12, it is determined whether or not _{the vehicle 1 satisfies the CO 2 recovery condition in each CO 2} recovery facility 2 based on the facility information acquired in step S11. For example, if the CO ₂ recovery condition comprises the recovery of CO ₂ from all of the vehicle is not required, ECU 30 determines that the vehicle 1 does not meet the CO ₂ recovery conditions in each CO ₂ recovery facility 2. As a result, when the CO ₂ recovery facility 2 does not want to recover the _{CO 2} , the vehicle 1 is suppressed from going to the _{CO 2 recovery facility 2.}

Further, for example, when the CO ₂ capture condition _{includes the lower limit of the CO 2} capture amount, the ECU 30 determines that _{the CO 2} capture amount _{captured by the CO 2} capture device 20 of _{the vehicle 1 is the CO 2 capture facility 2 for each CO 2} capture facility 2. It is determined whether or not it is larger than the lower limit of the amount of each CO ₂ captured under the CO _{2 recovery conditions of.} As a result, for example, CO ₂ recovery facility 2 is to prevent the vehicle 1 that does not have a trapping amount of only small amounts of about CO ₂ visits for recovery of CO _2, a sufficient amount of recovery of CO ₂ Only the vehicle 1 having the amount of CO ₂ captured can be accepted for the recovery of _{CO 2.} Therefore, it is possible to recover a lot of CO ₂ in a smaller number of recovery, the recovery efficiency of the CO ₂ in the CO ₂ recovery facility 2 is improved.

Hereinafter, an example of a method of calculating the amount of captured CO ₂ in the CO ₂ capturing apparatus 20 according to this embodiment. _{First, the ECU 30 calculates, for example, the amount of CO 2} captured Xt per unit time in the _{CO 2} capturing device 20 based on the following equation (1).
Xt = CQE _CO2 ... Equation (1)

Here, in the formula (1), C is the CO ₂ concentration detected by the CO ₂ concentration sensor 51, Q is the flow rate of the gas detected by the flow rate sensor 52, the E _CO2 is CO ₂ capture unit 21 CO ₂ capture efficiency. Incidentally, CO ₂ capture efficiency E _CO2 is calculated based on the temperature of the CO ₂ capture unit 21 detected by the temperature sensor 53.

_{Next, the ECU 30 multiplies the CO 2} capture amount Xt per unit time calculated using the equation (1) by the execution cycle T of this control routine, from the previous step S11 to the current step S11. to calculate the trapped amount Xt · T of the captured CO ₂ in CO ₂ capture apparatus 20 before. After that, the ECU 30 _{adds the calculated CO 2 capture amount Xt · T to the CO 2} capture amount X in _{the CO 2} capture device 20 updated in the previous step S11, _{thereby accumulating the CO 2} capture amount. (X + Xt · T) is calculated. Then, the ECU 30 stores and updates the cumulative value (X + Xt · T) in _{the memory as the current CO 2} capture amount X, as shown in the following equation (2).
X = X + Xt · T ... Equation (2)

Further, for example, when the CO ₂ recovery condition _{includes a time zone in which CO 2} can be recovered, the ECU 30 has a range of the time in which the vehicle 1 _{arrives at the CO 2} recovery facility 2 in the above-mentioned available time zone. Determine if it is within. For example, the ECU 30 calculates the estimated arrival time at _{each CO 2} recovery facility 2 based on the position information output from the positioning sensor 50 and the position information of each CO _{2 recovery facility 2 included in the facility information, and this arrival schedule} It is determined whether or not the time is within the above-mentioned available time zone. As a result, for example, it is possible to prevent a situation in which _{the vehicle 1 visits the CO 2} recovery facility 2 outside business hours and the CO _{2 is not recovered.}

Further, for example, when the CO ₂ recovery condition includes the above-mentioned recovery rate, the ECU 30 _{determines whether the recovery rate set in each CO 2} recovery facility 2 is higher than the recovery rate set in the vehicle 1 via the HMI 40. Is determined. As a result, for example, after the vehicle 1 _{visits the CO 2} recovery facility 2, it is possible to prevent a situation in which _{CO 2 is not recovered due to a price compromise.}

If it is determined in step S12 that the vehicle 1 _{does not satisfy the CO 2 recovery conditions in each CO 2} recovery facility 2, this control routine is terminated. On the other hand, if it is determined in step S12 that the vehicle 1 _{satisfies the CO 2 recovery condition in each CO 2} recovery facility, the control routine proceeds to step S13.

In step S13, the vehicle 1 is CO ₂ recovery satisfies the CO ₂ recovery facility 2 is displayed on the navigation map. Specifically, based on the facility information, the vehicle 1 is CO ₂ recovery satisfies the CO ₂ recovery facility 2 is displayed as the facility for recovering CO ₂ on the navigation map.

FIG. 5 shows an example of a navigation map displaying the _{CO 2 recovery facility 2.} 5 shows a navigation map indicating the own vehicle is traveling on a road, and the CO ₂ recovery satisfies the CO ₂ recovery facility, and CO ₂ recovery facility that does not meet the CO ₂ recovery condition, and other buildings, It is shown. In the navigation map shown in FIG. 5, for example, for the CO ₂ recovery facility that does not meet the CO ₂ recovery condition display normal it is made, whereas for other buildings have been made of displaying a dotted line, the CO ₂ recovery _{CO 2} recovery facilities that meet the conditions are highlighted (for example, displayed in a different mode (red, bold, etc.) from _{CO 2} recovery facilities that do not meet the _{CO 2 recovery conditions and other buildings).} As a result, the user viewed navigation map shown in FIG. 5, the CO ₂ to grasp a possible CO ₂ recovery facility 2 places recovery, it is possible to go to the CO ₂ recovery facility 2. Further, the present invention is not limited to the example shown in FIG. 5, and for example, even _{if the recovery rate set in the CO 2} recovery facility 2 is displayed on the navigation map for _{each CO 2} recovery facility 2 that _{satisfies the CO 2} recovery condition. Good. Moreover, CO ₂ for recovering satisfies CO ₂ recovery facility 2, indicating that the CO ₂ recovery satisfies the CO ₂ recovery facility 2 may be displayed on the navigation map.

Returning to FIG. 4, after step S13, the control routine is terminated.

<Second embodiment>
Next, the information display device according to the second embodiment will be described. The configuration of the information display device according to the second embodiment is basically the same as the configuration of the information display device according to the first embodiment. Hereinafter, a part different from the configuration of the information display device according to the first embodiment will be mainly described.

In the present embodiment, the display unit 34, on the navigation map, among the vehicle 1 is CO ₂ recovery satisfies the CO ₂ recovery facility 2, the user satisfying the CO ₂ recovery facility 2 set by the user the vehicle 1 , Highlight in a manner different from _{CO 2} recovery facility 2 that does not meet user requirements. As a result, the user vehicle 1 among the vehicle 1 is CO ₂ recovery satisfies the CO ₂ recovery facility 2 can grasp the user satisfies the CO ₂ recovery facility 2. Therefore, the user of the vehicle 1 can positively go to the _{CO 2 recovery facility 2 that satisfies the user condition.}

FIG. 6 is a flowchart showing a control routine in the ECU 30 according to the present embodiment. The illustrated control routine is executed at regular time intervals. Since the control in steps S21, S22 and S24 is the same as the control in steps S11, S12 and S13 of FIG. 4, the description thereof will be omitted.

After step S22, when the control routine proceeds to step S23, in step S23, whether the vehicle 1 is out of the CO ₂ recovery satisfies the CO ₂ recovery facility 2, there is a user satisfies the CO ₂ recovery facility 2 not Is determined. User conditions are set, for example, by the user of vehicle 1 via the HMI 40.

Examples of user conditions, among the vehicle 1 is CO ₂ recovery satisfies the CO ₂ recovery facility 2, price efficiency (hereinafter, simply referred to as "cost-effective") for CO ₂ recovery is higher than the predetermined reference value CO ₂ It can be mentioned that it is a collection facility 2. The predetermined reference value is appropriately set by the user of the vehicle 1 via the HMI 40, for example. Here, "cost-effective" indicates the cost effectiveness when the vehicle 1 is to recover the CO ₂ at a CO ₂ recovery facility 2. The price efficiency is calculated based on, for example, the difference between the estimated selling price _{of CO 2 at the target CO 2} recovery facility 2 _{and the fuel cost until the CO 2 recovery facility 2 is reached.} In this case, for example, assuming that the recovery rate is R, _{the mileage to the CO 2} recovery facility 2 is D, and the fuel cost per km in the vehicle 1 is F [yen / km], the ECU 30 uses the following equation (3). based on, for calculating the price efficiency E _p of CO ₂ recovery facility subject. In the following formula (3), X indicates the current amount _{of CO 2 captured, as described above.}
E _p = (estimated sales price)-(fuel cost) = R / X-D / F ... Equation (3)

Here, the average price of gasoline regions vehicle 1 is currently operated Circle / l] and F _G, the fuel consumption of the vehicle 1 [km / l] and F _E, the fuel cost F per km in the vehicle 1 Is calculated based on the following equation (4).
F = F _G / F _E ... formula (4)

The average gas prices F _G in the formula (4), for example, in response to on the basis of the output signal of the positioning sensor 50 that enters in the area from the area where there is the vehicle 1 is detected ECU30 Is acquired via the server 5. Moreover, fuel consumption F _E of the vehicle 1 in the formula (4) are, for example, is stored in advance in the memory of the ECU 30, it is acquired by being read out from the memory of the ECU 30.

_{The ECU 30 determines the CO 2} recovery facility 2 whose price efficiency calculated in this way is higher than a predetermined reference value. The method for calculating price efficiency represented by the above formulas (3) and (4) is merely an example, and is not limited thereto.

Further, for example, when the facility information _{further includes the CO 2} necessity information indicating whether or not the _{CO 2 necessity in the CO 2} recovery facility 2 is high, as another example of the user condition, the vehicle 1 has the CO ₂ recovery condition. of CO ₂ recovery facility 2 satisfying the need of the CO ₂ and the like to be high CO ₂ recovery facility 2. In this case, ECU 30, based on CO ₂ necessity information to determine the CO ₂ recovery facility 2 needs of the CO ₂ is shown to be high by the CO ₂ necessity information. In this case, for example, _{the administrator of the CO 2} recovery facility 2 sets such _{CO 2} necessity information via the client computer 3.

_{If it is determined in step S23 that there is no CO 2} recovery facility 2 that satisfies the user condition, the control routine proceeds to step S24. On the other hand, _{if it is determined in step S23 that there is a CO 2} recovery facility 2 that satisfies the user condition, the control routine proceeds to step S25.

In step S25, on the navigation map, with the vehicle 1 is CO ₂ recovery satisfies the CO ₂ recovery facility 2 is displayed as the facility for recovering CO ₂ based on the facility information, the vehicle 1 is CO ₂ recovery condition is satisfied Of the CO ₂ recovery facilities 2, the CO ₂ recovery facility 2 that satisfies the user conditions is highlighted in a manner different from _{that of the CO 2 recovery facility 2 that does not meet the user conditions.} For example, of the CO ₂ recovery satisfies the CO ₂ recovery facility 2, if the CO ₂ recovery facility 2 which does not satisfy the user condition is displayed in blue, the user satisfies the CO ₂ recovery facility 2 is displayed in red .. Further, for the CO ₂ recovery facility 2 that satisfies the user _{, the fact that the CO 2} recovery facility 2 satisfies the user condition may be displayed on the navigation map. After step S25, this control routine is terminated.
