Engineering Contradiction Analysis
1Quantity of substance
If the CO2 recovery device is operated continuously, then the amount of CO2 recovered increases, but the electric power consumed by the battery increases proportionally, resulting in poor recovery efficiency
Solution Approach 1:
The control device operates the CO2 recovery device periodically rather than continuously, activating it only during high efficiency recovery conditions (such as when CO2 concentration is above a threshold or during specific driving patterns). This periodic operation maintains CO2 recovery effectiveness while significantly reducing overall battery power consumption.
Solution Approach 2:
The system dynamically adjusts operational parameters based on detected conditions, including activating the recovery device only when CO2 concentration, driving distance, or engine temperature parameters meet predetermined thresholds. This parameter-based control optimizes the balance between CO2 recovery quantity and energy consumption.
2Reliability
If the CO2 recovery device is operated under all conditions, then CO2 recovery is maintained, but energy is wasted during low efficiency conditions such as short driving distances or cold engine operation
Solution Approach 1:
The control device evaluates predetermined conditions (driving distance, engine temperature, CO2 concentration) before activating the CO2 recovery device. By performing this preliminary assessment, the system ensures that recovery operations only commence when efficiency thresholds are met, preventing energy waste during unsuitable conditions while maintaining recovery reliability when conditions are favorable.
Solution Approach 2:
The system continuously monitors operational parameters and feedback from sensors (CO2 concentration, engine temperature, driving distance) to dynamically control recovery device operation. This feedback mechanism ensures the device operates only when efficiency conditions are satisfied, optimizing the balance between recovery consistency and energy conservation.
3Productivity
If the CO2 recovery device is activated during cold engine operation or short driving distances, then CO2 recovery occurs, but the recovery efficiency becomes poor due to insufficient operating conditions
Solution Approach 1:
The control device dynamically adjusts its operation based on real-time conditions, transitioning between active recovery mode and standby mode according to detected parameters such as engine temperature and driving distance. This dynamic control ensures high productivity during favorable conditions while avoiding energy waste during unfavorable conditions like cold operation or short trips.
Solution Approach 2:
The system uses predetermined parameter thresholds (engine temperature, driving distance, CO2 concentration) to control activation. By changing operational state based on these parameter changes, the system maintains high recovery rates when parameters indicate favorable conditions while preventing inefficient energy consumption when parameters indicate unsuitable conditions.

AI summary
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.
