Solution Overview

Problem

Existing vehicle entry systems that use image authentication for door operation are cumbersome when allowing non-registered individuals to board, as they require advance registration of all potential users, compromising security and convenience.

Innovation Solution

A vehicle control system that includes exterior and interior image acquisition units, a person recognition unit, a door control unit, and a motion determination unit, which allows authorized individuals to perform specific motions to unlock doors via near-field wireless communication, ensuring security while enabling smooth boarding for non-registered users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If all potential users are registered in advance in the vehicle, then any registered person can board the vehicle smoothly, but the preparation work becomes cumbersome and the system cannot accommodate unregistered persons

Engineering Contradiction:
Improveboarding convenienceVSAvoidregistration management complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system introduces a terminal device as an intermediary between the vehicle and unregistered persons. The terminal device stores motion information and communicates with the vehicle's recognition system, enabling unregistered persons to board by performing recognized motions without requiring advance registration in the vehicle's system.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary action by having the terminal device store motion information in advance. This pre-stored motion information is then used during the boarding process, allowing the vehicle to recognize and authorize specific motions without needing to register each person individually.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If iris recognition is used for door unlocking, then security is ensured for registered users, but the system cannot accommodate persons without registered iris data

Engineering Contradiction:
Improvevehicle securityVSAvoiduser acceptance flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system replaces the biological iris recognition mechanism with an artificial motion recognition system. Instead of relying on unique biological characteristics that require advance registration, the system uses observable physical motions that can be recognized and authorized through the terminal device, thereby accommodating unregistered persons while maintaining security.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the authentication parameter from static biological data (iris patterns) to dynamic behavioral data (motion sequences). This parameter change allows the system to authenticate unregistered persons based on their performance of specific motions rather than requiring pre-registered biological identifiers.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If motion recognition is implemented for door opening, then unregistered persons can board the vehicle, but the system complexity increases with image acquisition and motion analysis

Engineering Contradiction:
Improveunregistered user acceptanceVSAvoidimage processing system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the motion recognition functionality into two parts: the vehicle's image acquisition unit that captures motion data, and the terminal device that stores and provides motion information for comparison. This segmentation reduces the processing burden on the vehicle system while enabling comprehensive motion recognition capabilities.

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention includes: a vehicle exterior image acquisition unit acquiring a vehicle exterior image, a vehicle interior image acquisition unit acquiring a vehicle interior image, a person recognition unit recognizing, based on the vehicle exterior and interior images, a presence of a person in the vehicle and a motion of a person outside the vehicle, a door control unit controlling a state of a door of the vehicle, and a motion determination unit determining a specific motion to be carried out when the person outside the vehicle instructs an opening operation of the door, wherein the door control unit executes the opening operation when the person outside the vehicle has performed the specific motion, if the presence of a person in the vehicle has been recognized based on a recognition result of the person recognition unit.
