Parking Guidance Indicator Switching for Stage Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assistance apparatuses require drivers to understand different display images and guidance methods at various parking stages, making it difficult to align the vehicle with the completion position of each stage.
Innovation Solution
A parking assistance apparatus that switches between first, second, and third parking guidance indicators to guide the vehicle to specific positions, maintaining constant relative positional relationships between the indicators and the vehicle's image data throughout each guidance stage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple different display images and guidance methods are used for different parking stages, then the guidance information is comprehensive and covers all parking phases, but the driver finds it difficult to understand and align the vehicle with the completion position of each stage
Solution Approach 1:
The parking guidance is divided into three distinct stages (first parking guidance to parking start position, second parking guidance to steering wheel reversal start position, and third parking guidance to final parking position), with each stage having its own dedicated indicator. This segmentation allows the driver to focus on one stage at a time, understanding only the current guidance requirement rather than trying to comprehend multiple different guidance systems simultaneously.
Solution Approach 2:
Each parking guidance indicator uses distinct color coding to represent different parking stages. The first parking guidance indicator, second parking guidance indicator, and third parking guidance indicator are displayed in different colors, providing intuitive visual differentiation. This color-coding system enables drivers to quickly identify which stage they are in and what alignment action is required, eliminating confusion from multiple different display images.
2Measurement precision
If conventional parking assistance displays different marker positions for each stage, then the guidance is stage-specific, but the driver cannot easily understand how to align the vehicle with the completion position
Solution Approach 1:
The parking guidance indicators serve as visual intermediaries that represent the relationship between the vehicle's current position and the target completion position for each stage. Rather than displaying abstract marker positions that require interpretation, the indicators directly show the alignment relationship, making it intuitive for drivers to understand how to position the vehicle at each stage's completion point.

AI summary
Disclosed is a parking assistance device such that it is easy to understand the process for aligning the vehicle with the guidance completion position of each stage of parking, specifically the parking start position, the steering wheel reversal position and the intended parking position. Specifically disclosed is a parking assistance device wherein a control device (11) switches to a first parking guidance indicator (45A) during first parking guidance for guiding the vehicle to the parking start position, switches to a second parking guidance indicator (45B) during second parking guidance for guiding the vehicle to the steering wheel reversal start position, and switches to a third parking guidance indicator (45C) during third parking guidance for guiding the vehicle to the final parking position.
