Abstract

A vehicle includes a battery and a CO2 recovery device using electric power of the battery to recover CO2 contained in inflowing gas. A control device mounted in the vehicle controls the CO2 recovery device. The control device permits operation of the CO2 recovery device in the case where a high efficiency recovery condition, at which it is predicted that the efficiency of recovery of CO2, showing a ratio of the amount of recovery of CO2 in the CO2 recovery device with respect to the electric power consumed by the battery, will become equal to or greater than a preset predetermined efficiency, is satisfied, and prohibits operation of the CO2 recovery device in the case where the high efficiency recovery condition is not satisfied.

First claim

The invention claimed is:

1. A control device mounted in a vehicle including a battery and a CO 2 recovery device configured to use electric power of the battery to recover CO 2 contained in gas flowing into the CO 2 device, the control device being programmed to:
control the CO 2 recovery device, including:
operate the CO 2 recovery device under a high efficiency recovery condition, wherein it is predicted that an efficiency of recovery of CO 2 , measured as a ratio of the amount of recovery of CO 2 in the CO 2 recovery device with respect to the electric power consumed by the battery, will become equal to or greater than a preset predetermined efficiency, and
prohibit operation of the CO 2 recovery device in the case where the high efficiency recovery condition is not satisfied.

2. The control device according to claim 1 , wherein
the gas flowing into the CO 2 recovery device is a gas discharged from an internal combustion engine mounted in the vehicle,
the CO 2 recovery device includes:
a CO 2 recovery part configured to recover CO 2 in the gas flowing into the CO 2 recovery device;
a cooling part configured to use the electric power of the battery to cool the CO 2 recovery part; and
a suction pump configured to use the electric power of the battery to suck in the gas and make the gas flow to the CO 2 recovery part, and
the control device is configured to operate the cooling part and the suction pump when the high efficiency recovery condition is satisfied, and prohibit operations of the cooling part and the suction pump when the high efficiency recovery condition is not satisfied.

3. The control device according to claim 1 , wherein
the control device is programmed to:
operate the CO 2 recovery device under the high efficiency recovery condition when it is predicted that the vehicle will be driven a predetermined distance or more; and
prohibit the operation of the CO 2 recovery device when the high efficiency recovery condition is not satisfied, and it is predicted that the vehicle will not be driven a predetermined distance or more.

4. The control device according to claim 1 , wherein
the control device is programmed to:
operate the CO 2 recovery device under the high efficiency recovery condition when a water temperature of the internal combustion engine of the vehicle is equal to or greater than a predetermined temperature; and
prohibit the operation of the CO 2 recovery device when the high efficiency recovery condition is not satisfied, and the water temperature is lower than the predetermined temperature.

5. The control device according to claim 1 , wherein
the control device is programmed to:
operate the CO 2 recovery device under the high efficiency recovery condition when a predetermined time has elapsed from cold start of the internal combustion engine of the vehicle; and
prohibit the operation of the CO 2 recovery device when the high efficiency recovery condition is not satisfied, and the predetermined time has not elapsed from cold start.

6. The control device according to claim 1 , wherein
the gas flowing into the CO 2 recovery device is air around the vehicle,
the CO 2 recovery device includes:
a CO 2 recovery part configured to recover CO 2 in the gas flowing into the CO 2 recovery device; and
a suction pump configured to use the electric power of the battery to suck in the gas and make the gas flow to the CO 2 recovery part, and
the control device being programmed to:
operate the CO 2 recovery device under the high efficiency recovery condition when a concentration of CO 2 contained in the air around the vehicle is equal to or greater than a predetermined threshold value; and
prohibit the operation of the CO 2 recovery device when the high efficiency recovery condition is not satisfied and the concentration of CO 2 is lower than the predetermined threshold value.

7. The control device according to claim 1 , wherein
the vehicle further includes a user interface screen configured for receiving an operation prohibit instruction for prohibiting the operation, from a user of the vehicle, and
the control part is programmed to prohibit the operation even when the high efficiency recovery condition is satisfied, when the user interface screen receives the operation prohibit instruction.
