Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for remote air conditioning in hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) do not adequately control the air conditioner based on remote operation, potentially leading to excessive fuel consumption or environmental impact.
Innovation Solution
An information processing device that controls a vehicle to execute two modes: a first mode using electric power from the battery and a second mode using electric power generated from the internal combustion engine's dynamic power, based on remote operation requests and battery and fuel thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the air conditioner is actuated by electric power from the battery in remote operation mode, then the fuel consumption is reduced, but the battery may be depleted too quickly when the remaining amount is below the first threshold
Solution Approach 1:
The system changes the power source parameter dynamically based on the battery's remaining amount. When the remaining amount is above the first threshold, the air conditioner uses battery power. When it drops below the threshold, the system switches to using the internal combustion engine's generated power, thus adapting the power source parameter to current battery status to ensure continuous reliable operation.
Solution Approach 2:
The control device acts as an intermediary that manages power source selection. It monitors the battery's remaining amount and automatically switches between battery power and engine-generated power, serving as a mediator that ensures continuous power supply while optimizing fuel consumption based on real-time battery status.
2Reliability
If the internal combustion engine is actuated to generate power for the air conditioner, then the continuous power supply is ensured, but the fuel consumption and environmental impact increase
Solution Approach 1:
The system applies partial action by using the internal combustion engine only when necessary (when battery remaining amount is below the first threshold). This partial engagement of the engine avoids continuous operation, thereby ensuring power supply reliability only when needed while minimizing fuel consumption and environmental impact.
Solution Approach 2:
The system changes the power source parameter dynamically based on the battery's remaining amount. When the remaining amount is above the first threshold, the air conditioner uses battery power. When it drops below the threshold, the system switches to using the internal combustion engine's generated power, thus adapting the power source parameter to current battery status to ensure continuous reliable operation.
3Ease of operation
If the air conditioner is controlled based on remote operation without considering battery status, then the user convenience is maintained, but the system may not optimally manage power resources
Solution Approach 1:
The control device incorporates feedback by continuously monitoring the battery's remaining amount and automatically adjusting the power source selection. This feedback mechanism allows the system to maintain user convenience through remote operation while optimizing power resource management by switching between battery and engine power based on real-time battery status.
Solution Approach 2:
The system performs self-service by automatically managing power source selection without requiring user intervention. The control device autonomously monitors battery status and switches power sources as needed, maintaining ease of remote operation while improving power resource management efficiency through automated decision-making.

AI summary
An information processing device controls a vehicle that executes a first mode in which an air conditioner is actuated by electric power of a battery and a second mode in which the air conditioner is actuated by electric power generated using dynamic power of an internal combustion engine. The information processing device includes a processor. The processor determines whether the remaining amount of the battery is equal to or higher than a first threshold, in response to receiving an actuation request for the air conditioner by a remote operation. The processor determines whether a predetermined condition as an execution condition for the second mode is satisfied, when determination is made that the remaining amount of the battery is less than the first threshold. The processor controls the vehicle such that the second mode is executed, when determination is made that the predetermined condition is satisfied.
