Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In automated valet parking, occupants face uncertainty and anxiety due to unpredictable vehicle movement routes and delays, which degrade the convenience of the automated exit process.

Innovation Solution

A vehicle control device and method that transmits information on the vehicle's route, position, and external environment to a terminal device, including route changes and delay notifications, to inform occupants about the vehicle's status during automated exit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If automated exit process is implemented with variable movement routes, then automation level is improved, but occupant anxiety increases due to inability to infer delay causes

Engineering Contradiction:

Improveautomated exit processVSAvoidoccupant anxiety

Core Design Contradiction:

Extent of automationVSObject-affected harmful factors

Solution Approach 1:

The system provides real-time feedback to occupants about vehicle status during automated exit. The notification device transmits information about current position, route progress, and delay causes to the occupant's terminal device, allowing occupants to understand what is happening even though they cannot control the process. This feedback mechanism reduces anxiety by making the automated process transparent and predictable.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The notification device acts as an intermediary between the automated vehicle control system and the occupant. It translates complex automated operations into understandable information about position, route, and status, bridging the gap between the automated system and human understanding without requiring direct occupant control.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If route information is transmitted to terminal device, then information transparency is improved, but communication data load increases

Engineering Contradiction:

Improveinformation transparencyVSAvoidcommunication data

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The system extracts and transmits only the most essential information needed for occupant awareness: current position, route progress, and delay causes. Rather than transmitting all possible vehicle data, the notification device selectively outputs only critical status information, reducing communication load while maintaining transparency.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The information transmission is targeted and context-specific. The notification device provides different types of information at different stages of the automated exit process, such as position information during movement and delay cause information when stopped, optimizing data transmission based on the current operational context.

Inventive Principle:

Principle #3Local quality
