Parking Control for Narrow-Space Positional Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking support systems do not adequately consider the movement space breadth available for a vehicle's movement path when determining parking control, leading to potential interference with obstacles and inconsistent ride comfort based on the presence or absence of an occupant.
Innovation Solution
A parking support system that includes a space recognition part to determine the movement space breadth, applying narrow environment settings to increase positional accuracy when the space is narrow and normal settings when space is ample, ensuring both accurate parking and occupant comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle control part applies a narrow environment setting to increase positional accuracy when movement space breadth is narrow, then the positional accuracy of the vehicle is improved, but the motion of the vehicle is restricted
Solution Approach 1:
The control setting is dynamically adjusted based on the determined movement space breadth. When the movement space breadth is narrow, the narrow environment setting is applied to increase positional accuracy. When the movement space breadth is sufficient, the normal environment setting is applied to allow greater vehicle motion. This dynamic adjustment resolves the contradiction by adapting the control characteristics to the actual spatial conditions.
2Ease of operation
If the vehicle control part applies a normal environment setting to allow increased vehicle motion, then the ride comfort of the occupant is improved, but the positional accuracy of the vehicle decreases
Solution Approach 1:
Different control settings (narrow environment setting and normal environment setting) are applied locally based on the specific condition of movement space breadth. The normal environment setting with more permissive motion parameters is applied only when the movement space breadth is sufficient, providing improved ride comfort. The narrow environment setting with stricter position control is applied when space is constrained, ensuring positional accuracy. This local quality approach allows each control mode to optimize for its intended purpose.
3Device complexity
If the system only considers whether an occupant is present in the vehicle for parking control, then the control logic is simple, but it cannot adequately handle cases where movement space breadth is narrow
Solution Approach 1:
The space recognition part performs preliminary recognition of the movement space breadth before the vehicle control part executes parking control. The breadth determination part determines the movement space breadth in advance, and based on this preliminary information, the appropriate control setting (narrow environment or normal environment) is selected before parking control begins. This preliminary action allows the system to adapt to narrow movement spaces without significantly increasing control logic complexity during execution.

AI summary
A parking support system includes: a space recognition part configured to recognize a travel space (M) and a parking space (P); a breadth determination part configured to determine at least one of a width (B1) of an entrance (E) and a length (B2), of the travel space (M), in a direction orthogonal to the width (B 1) of the entrance (E), as a movement space breadth (B); and a vehicle control part configured to perform parking control through which a vehicle (50) is moved into and stopped in the parking space (P), on the basis of relative positions of the parking space (P) and the travel space (M) with respect to the vehicle (50). The vehicle control part is configured to apply, in a case in which the movement space breadth (B) is determined to be narrower than a determination criterion, a narrow environment setting that is a control setting for a narrow environment to increase positional accuracy of the vehicle (50) by allowing increased motion of the vehicle (50), as compared with a case in which the movement space breadth (B) is determined to be a breadth of the determination criterion or more.
