Parking Assist Candidate Position Ranking by Vehicle Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assist systems do not effectively determine a candidate position for smoother or less inconvenient parking, as they lack a method to rank potential positions based on vehicle orientation and obstacle detection results.
Innovation Solution
A parking assist system that includes an electronic control unit to set candidate positions, determine vehicle orientation at each position, and rank these positions based on vehicle and candidate position orientations, allowing for the selection of the most suitable target position for parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a parking assist system selects a parking space based on simple rules (e.g., opposite to turning direction), then the system complexity is reduced, but the parking smoothness and convenience deteriorate
Solution Approach 1:
The system performs preliminary actions by calculating and ranking multiple candidate positions and their associated vehicle orientations before executing the parking maneuver. The ECU evaluates potential target positions, determines the orientation required at each position, ranks them based on orientation changes, and selects the optimal target position in advance, ensuring smooth and convenient parking execution.
2Ease of operation
If the system evaluates multiple candidate positions with orientation analysis, then the parking smoothness is improved, but the computational complexity increases
Solution Approach 1:
The system segments the parking decision-making process into distinct components: identifying candidate positions, determining vehicle orientation at each position, ranking positions based on orientation changes, and selecting the optimal target. This segmentation allows the ECU to systematically evaluate multiple factors without overwhelming computational complexity, as each segment can be processed independently and efficiently.

AI summary
A parking assist system includes an electronic control unit configured to: set at least one candidate position that is a candidate for a target position of a moving path of a vehicle on the basis of at least one of a detection result of an obstacle and a detection result of a parking boundary; set an orientation of the vehicle at each of the at least one candidate position, as a candidate position vehicle orientation, on the basis of at least one of the detection result of the obstacle and the detection result of the parking boundary; rank each of the at least one candidate position on the basis of an orientation of the vehicle and the candidate position vehicle orientation; and determine one of the ranked at least one candidate position as the target position.
