Parking Assistance Control for Undefined Space Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In parking areas without defined boundary lines, vehicles often inefficiently utilize space, leading to unsatisfactory parking conditions when adjacent vehicles leave, as existing technologies fail to consider the potential use of space by other vehicles during parking.
Innovation Solution
A parking assistance device that includes a recognition part to acquire surroundings information, a parking region determiner to identify spaces between vehicles, and an automatic parking controller to park the vehicle centrally or closer to another vehicle based on entry width, ensuring efficient space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the host vehicle parks in a parking region with available space without considering future usage by other vehicles, then the parking operation is simple and quick, but efficient utilization of space by individual vehicles within the parking area is jeopardized
Solution Approach 1:
The parking location determiner performs preliminary analysis of the parking region characteristics (entry width) before finalizing the parking location. When the entry width is equal to or greater than a predetermined value, the system proactively selects a location closer to one other vehicle to reserve space for future arrivals, rather than simply choosing any available spot.
Solution Approach 2:
The parking location determination is made dynamic based on the entry width condition. The system adapts its parking location selection strategy according to the specific characteristics of the parking region, switching between central location (narrow entry) and offset location (wide entry) to optimize both current parking ease and future space utilization.
2Ease of operation
If the host vehicle parks in a parking region with no consideration regarding efficient use of space, then the parking operation is straightforward, but the host vehicle would be left with unsatisfactory spaces on both its sides once an adjacently parked vehicle has left
Solution Approach 1:
The system changes the parking location parameter based on the entry width parameter. When entry width is sufficient (≥ predetermined value), the parking location is shifted closer to one vehicle, creating an asymmetric arrangement that optimizes future space utilization while maintaining adequate current accessibility.
3Device complexity
If the parking location is determined without considering entry width, then the parking system is simpler, but efficient space utilization cannot be achieved in parking regions with sufficient width
Solution Approach 1:
The parking location determiner uses entry width as a key parameter to determine parking location strategy. This parameter-based approach allows the system to adapt its behavior to different parking region characteristics without requiring complex algorithms, achieving efficient space utilization through simple conditional logic.

AI summary
A parking assistance device including a recognition part configured to acquire recognition information through recognition of surroundings, a parking region determiner configured to determine a space between other vehicles as a parking region of the host vehicle based on the recognition information, an automatic parking controller configured to perform a parking operation to park the host vehicle in the parking region, and a parking location determiner. In response to determining that an entry width of the parking region is less than a predetermined value, the parking location determiner is configured to determine a parking location of the host vehicle in the parking region that is at a central location as viewed from an entry side of the parking region. In response to determining that the entry width is equal to or greater than the predetermined value, the parking location determiner is configured to determine the parking location that is closer to one of the other vehicles as viewed from the entry side.
