Solution Overview

Problem

Existing parking support systems fail to address the issue of an automatically driven vehicle becoming immobile in a parking lot due to an abnormality, which can hinder the movement of other vehicles.

Innovation Solution

A management device equipped with an abnormality determiner and a notification instructor, which detects abnormalities in automatically driven vehicles and sends notifications to users via portable terminal devices, instructing them to collect their vehicles at designated positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automatic driving is implemented in parking facilities, then parking efficiency and convenience are improved, but the risk of vehicle abnormalities causing obstruction to other vehicles increases

Engineering Contradiction:

Improveparking efficiencyVSAvoidobstruction to other vehicles

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary abnormality detection before the vehicle completes its parking task. The management device monitors vehicle status during automatic driving and notifies the user in advance if an abnormality is detected, allowing the user to retrieve the vehicle before it can obstruct other vehicles in the parking facility.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements continuous feedback monitoring of vehicle status during automatic driving. The management device receives status information from the automatically driven vehicle, determines whether abnormalities have occurred, and provides feedback to the user through notifications, enabling real-time response to potential obstruction risks.

Inventive Principle:

Principle #23Feedback

2Object-affected harmful factors

If abnormality detection and notification systems are added, then vehicle obstruction is reduced, but device complexity increases

Engineering Contradiction:

Improvevehicle obstructionVSAvoidsystem complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The management device serves as an intermediary between the automatically driven vehicle and the user. It centralizes the abnormality detection logic and notification functionality, so that individual vehicles do not need complex onboard systems. The management device monitors vehicle status, determines abnormalities, and communicates with users, simplifying the overall system architecture while maintaining effective obstruction prevention.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A parking support device configured to support an automatic valet parking of a vehicle includes: an abnormality determiner configured to determine a presence or absence of an abnormality in an automatically driven vehicle when the automatically driven vehicle moves in a parking facility by automatic driving; and a notification instructor configured to issue, when determining an abnormality, a notification instruction for a portable terminal device held by a user of the automatically driven vehicle, notifying contents including (i) collection information indicating a collection position where the user should collect the automatically driven vehicle, and (ii) prompter information prompting that the user should go to the collection position.
