Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle control devices do not adequately determine whether to approve control requests from user applications based on vehicle status, potentially compromising safety or reducing user value.

Innovation Solution

A control device that includes a first obtainer to receive control requests from user applications, a second obtainer to obtain vehicle status, and a determiner to approve or reject the control requests based on the vehicle's status, ensuring safety and user value.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If control requests from user applications are approved without checking vehicle status, then user value and application functionality are improved, but vehicle safety deteriorates

Engineering Contradiction:

Improveuser application control capabilityVSAvoidvehicle safety

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The control device obtains vehicle status information before approving control requests from user applications. By performing this preliminary check, the system ensures that control actions are only approved when the vehicle is in a safe state, preventing safety issues while maintaining user application functionality.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If control requests are strictly approved based on vehicle status, then vehicle safety is improved, but user value and application functionality deteriorate

Engineering Contradiction:

Improvevehicle safetyVSAvoiduser application control capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The control device dynamically adjusts approval decisions based on real-time vehicle status. When the vehicle is in a safe state, control requests are approved to maintain user value; when the vehicle status indicates potential danger, requests are rejected to ensure safety. This dynamic approach resolves the contradiction by adapting the approval behavior to current conditions.

Inventive Principle:

Principle #15Dynamics

3Reliability

If vehicle status checking is implemented for control requests, then vehicle safety is improved, but device complexity increases

Engineering Contradiction:

Improvevehicle safetyVSAvoidcontrol device structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The control device leverages existing vehicle status monitoring infrastructure that is already present in modern vehicles. By reusing these existing sensors and status indicators for the purpose of control request approval, the system achieves enhanced safety without adding significant complexity, as the status checking functionality is integrated into the existing control architecture.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A control device provided to a vehicle includes: a first obtainer that obtains, from a user application, a control request for controlling a vehicle device of the vehicle; a second obtainer that obtains a vehicle status of the vehicle; and a determiner that determines whether to approve the control request, based on the vehicle status.
