Control device controlling co2 recovery device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CO2 recovery devices often operate at poor efficiency, failing to recover a sufficient amount of CO2 relative to the electric power consumed by the battery, leading to inefficient use of energy.
Innovation Solution
A control device is implemented to manage the operation of the CO2 recovery device, ensuring it operates only under high efficiency conditions, such as when the vehicle is driven a long distance or for an extended period, thereby optimizing CO2 recovery by adjusting the suction pump and cooling part's power usage based on predetermined criteria.

Engineering Contradiction Analysis
1Quantity of substance
If the CO2 recovery device is operated continuously to maximize CO2 recovery, then the amount of CO2 recovered increases, but the electric power consumed by the battery increases proportionally, reducing overall efficiency
Solution Approach 1:
The control device operates the CO2 recovery device periodically rather than continuously. It determines operation timing based on predicted driving patterns, operating the recovery device during periods when high CO2 recovery is expected (such as during sustained driving conditions) and stopping during periods when recovery efficiency would be low, thereby achieving periodic action that optimizes the balance between CO2 recovery quantity and energy consumption
2Productivity
If the CO2 recovery device operates under all driving conditions, then CO2 recovery opportunity increases, but recovery efficiency deteriorates under poor conditions
Solution Approach 1:
The control device performs preliminary determination of driving patterns and predicts future driving conditions before actually operating the CO2 recovery device. By analyzing current and predicted driving patterns in advance, the system pre-determines the optimal timing for operation, ensuring that the recovery device only operates when high recovery efficiency is anticipated, thus maintaining high reliability while maximizing recovery opportunities

AI summary
A vehicle (1) includes a battery (50) and a CO2 recovery device (20) using electric power of the battery (50) to recover CO2 contained in inflowing gas. A control device (30) mounted in the vehicle (1) controls the CO2 recovery device (20). The control device (30) permits operation of the CO2 recovery device (20) 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 (20) with respect to the electric power consumed by the battery (50), will become equal to or greater than a preset predetermined efficiency, is satisfied, and prohibits operation of the CO2 recovery device (20) in the case where the high efficiency recovery condition is not satisfied.
