Parking Path Correction for User-Selected Vehicle Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assistance systems often result in vehicles being parked in undesirable orientations despite user preferences, necessitating repetitive teacher traveling to correct the parking mode.
Innovation Solution
A parking assistance method that stores information on a teacher path, allows for user instruction to change parking modes, and corrects the teacher path accordingly to achieve the desired parking orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated parking assistance is performed using a learned teacher path, then parking automation is achieved, but the vehicle is parked in an undesirable mode (e.g., oblique stopping) when the teacher traveling was performed in that mode
Solution Approach 1:
The system performs preliminary correction of the teacher path after teacher traveling is completed. The correction information generation unit generates correction information based on the difference between the actual parking mode and the desired parking mode, which is then used to correct the teacher path before subsequent automated parking operations. This preliminary action ensures that automation does not perpetuate errors.
Solution Approach 2:
The system implements feedback by comparing the actual parking mode achieved during teacher traveling with the desired parking mode, generating correction information from this difference. This feedback loop allows the system to learn from past parking attempts and continuously improve parking accuracy in subsequent automated operations.
2Manufacturing precision
If the user retries teacher traveling to achieve the desired parking mode, then parking position accuracy can be improved, but the user burden and time consumption increase
Solution Approach 1:
The system performs self-correction of the teacher path automatically without requiring user intervention or retrying of teacher traveling. The correction information generation unit autonomously generates correction information based on the difference between actual and desired parking modes, and the teacher path correction unit automatically applies these corrections. This self-service capability eliminates the need for users to repeatedly perform teacher traveling to achieve accurate parking.
Solution Approach 2:
The system performs preliminary correction of the teacher path after a single teacher traveling session, rather than requiring multiple retries. By generating and applying correction information immediately after the initial teacher traveling, the system prepares an accurate reference path for future automated parking operations, saving user time and effort.
3Manufacturing precision
If the teacher path is corrected based on user input, then parking in the intended mode is achieved, but the system complexity increases
Solution Approach 1:
The system extracts only the essential correction information needed for path correction, separating the correction functionality from the overall automated parking system. The correction information generation unit specifically extracts the difference between actual and desired parking modes, and the teacher path correction unit applies only the necessary corrections to the relevant portions of the teacher path, minimizing added complexity.
Solution Approach 2:
The correction information generation unit and teacher path correction unit serve multiple functions: they not only correct parking position accuracy but also adapt to different desired parking modes (e.g., parallel, perpendicular, oblique parking). This multi-functionality allows a single correction mechanism to handle various parking scenarios without proportionally increasing system complexity.
