Solution Overview

Problem

Autonomous driving vehicles lack the ability to independently determine if they are parked at a correct reference parking location, as they do not have a vehicle occupant to observe the surroundings.

Innovation Solution

A vehicle parking finder support system that uses a combination of cameras and object recognition processing to compare image data of the vehicle's surroundings with stored reference image data, determining if the vehicle is at the correct parking location based on identified objects and their attributes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a vehicle occupant manually observes surroundings to verify parking location, then parking accuracy can be maintained, but the system cannot be applied to autonomous vehicles without occupants

Engineering Contradiction:
Improveautonomous parking capabilityVSAvoidparking location verification accuracy
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The system enables the autonomous vehicle to perform its own parking verification independently without human intervention. The vehicle captures images of surroundings, automatically processes them through object recognition, and compares identified objects with pre-stored reference data to determine if it is parked at the correct location.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual observation and verification process performed by the vehicle occupant is replaced with an automated computer vision system. Cameras capture visual data, object recognition algorithms process the images to identify relevant objects and features, and automated comparison logic determines parking accuracy without mechanical human involvement.

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

2Ease of operation

If GPS is used to determine vehicle location, then positioning capability is provided, but accuracy is insufficient near buildings, trees, or underground areas

Engineering Contradiction:
Improvelocation determination capabilityVSAvoidparking location accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system combines multiple positioning approaches by integrating visual recognition of environmental features with GPS coordinates. Object recognition identifies distinctive objects and features in the captured images, and this visual location information is merged with GPS data to achieve accurate parking verification even in areas where GPS alone is insufficient.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Visual features and objects captured in the environment serve as intermediary reference points between the vehicle and the parking location verification system. Instead of relying solely on direct GPS signals, the system uses recognized objects (buildings, trees, signs, etc.) as intermediate references to determine if the vehicle is at the correct parking location.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If reference image data is stored for comparison, then parking location verification is enabled, but the system must handle changes in surroundings over time

Engineering Contradiction:
Improveparking verification accuracyVSAvoidhandling of environmental changes
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The reference data system is made dynamic rather than static. The system stores multiple sets of reference image data captured at different times, and the object recognition process adapts to identify consistent objects across temporal changes. This allows the system to maintain reliable verification accuracy while adapting to environmental changes such as seasonal variations, construction, or moved objects.

Inventive Principle:
Principle #15Dynamics
