Automatic Parking Control Using Illuminance-Based Feature Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic parking systems struggle with accurately recognizing feature points in varying environments, leading to potential failure in automatic parking control due to mismatches in feature point information caused by environmental changes.
Innovation Solution
A moving body control device that utilizes outside recognition units to acquire data, receives user-designated parking positions, and performs automatic parking control based on illuminance patterns, registering feature points to ensure accurate parking even with changing environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If feature point information is stored in memory for automatic parking control, then automatic parking can be performed based on stored information, but the target parking space may not be recognized when there is a mismatch due to environmental changes
Solution Approach 1:
The system performs preliminary registration of feature points at the parking space before automatic parking is executed. Multiple feature points are registered in advance under different illuminance conditions (daytime, nighttime, etc.), creating a library of reference data that can be matched during actual parking operations to ensure reliable recognition regardless of environmental changes.
Solution Approach 2:
The system changes the parameter of illuminance conditions by registering feature points under multiple different illuminance levels. This allows the automatic parking control to select and compare against appropriate reference data based on current lighting conditions, maintaining recognition accuracy across varying environments.
2Adaptability or versatility
If feature point information is acquired during manual driving and parking, then automatic parking control can be performed based on this information, but mismatches occur when the environment around the vehicle changes
Solution Approach 1:
The system segments the feature point information by dividing it into multiple categories based on illuminance conditions (daytime, nighttime, etc.). Each segment contains feature points registered under specific lighting conditions, allowing the system to select the appropriate segment for comparison during automatic parking, thereby maintaining measurement precision across different environments.
3Ease of operation
If a single pattern of feature points is used for parking recognition, then the system is simple to operate, but it cannot adapt to different illuminance conditions
Solution Approach 1:
The system achieves universality by creating a multi-functional feature point registration system that handles multiple illuminance conditions. The same automatic parking operation can adaptively use different feature point patterns based on current lighting conditions, making the system universally applicable across daytime, nighttime, and other lighting scenarios without requiring different operations.

AI summary
A moving body control device includes an outside recognition unit configured to acquire recognition data of an outside of a moving body, a reception unit which receives designation of a predetermined parking position from a user of the moving body, and a control unit configured to perform automatic parking control for parking the moving body at the predetermined parking position based on the recognition data of the outside and the predetermined parking position, and register the predetermined parking position as a designated parking position. The control unit is configured to register feature points related to the designated parking position by using a plurality of patterns based on illuminance of the outside calculated from the recognition data of the outside.
