Solution Overview

Problem

Existing remote air conditioning technologies for hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) often operate in modes not intended by the user, reducing convenience due to automatic mode selection.

Innovation Solution

An information processing device that allows users to specify and control two modes for remote air conditioning operation: one without operating the internal combustion engine, and another with the engine operating to charge the battery, ensuring user-preferred mode execution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If automatic mode selection is implemented for remote air conditioning, then the system can operate autonomously without user input, but user convenience deteriorates because the system may execute modes not intended by the user

Engineering Contradiction:
Improveautomatic mode selectionVSAvoiduser convenience
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The system performs preliminary action by having the user specify their preferred mode in advance through a setting screen before actual remote air conditioning operation. This pre-specification ensures that when the user later activates remote cooling or heating, the system executes the pre-defined user-intended mode rather than making automatic decisions that may not align with user preferences.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the system provides detailed mode selection options, then user control and convenience improve, but device complexity increases due to additional control interfaces and processing

Engineering Contradiction:
Improveuser controlVSAvoidcontrol interface complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system applies local quality by providing detailed mode selection options specifically at the setting phase (when the user initially configures preferences), while keeping the actual remote operation phase simple (where the user just needs to activate pre-configured settings). This concentrates the complexity management in one localized area of the user experience rather than distributing it throughout all operations.

Inventive Principle:
Principle #3Local quality

AI summary

An information processing device that executes remote control on a vehicle that executes a first mode in which an air conditioner is operated without operating an internal combustion engine, and a second mode in which the air conditioner is operated by operating the internal combustion engine. The information processing device include one or more processors. The one or more processors are configured to acquire a user-specified mode that is the first mode or the second mode and is specified by a user of the vehicle, and transmit an execution request for the user-specified mode to an external device related to the vehicle in response to acquiring of the user-specified mode.
