Dynamic Parking Track Adjustment for Obstacle Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assisting apparatuses face challenges in setting an efficient target track for vehicles, leading to inconvenience when the target parking position changes, as they often require a rigid parking start position setting, which can depart from the ordinary start position and impair convenience.
Innovation Solution
A parking assisting apparatus that detects the positional relationship between obstacles and a parking section line to dynamically adjust the target track's turning radius and length, allowing for efficient path calculation even without detected parking section lines, by using sensors and image recognition to determine the optimal target track based on obstacle positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the parking start position is set farther with respect to the target parking position to obtain a sufficient margin, then the situation where it becomes impossible to create the target track is not likely to occur, but the parking start position has to be inefficiently set under a rigid constraint and may largely depart from the ordinary parking start position
Solution Approach 1:
The parking assistance device dynamically adjusts the target track based on the detected positional relationship between obstacles and parking section lines. The control section modifies the target track in real-time according to obstacle positions, allowing the system to maintain reliability while adapting to different parking scenarios and avoiding the need for a fixed, conservative start position.
Solution Approach 2:
The system changes parameters of the target track (turning radius, length of straight line section) based on detected obstacle positions and parking section line relationships. By adjusting these parameters dynamically, the system can create efficient target tracks for various situations without requiring a uniformly distant start position.
2Reliability
If the parking start position is set farther to ensure sufficient margin, then the target track can be calculated with a large margin, but the improvement in convenience of the parking assist may be impaired due to the rigid constraint
Solution Approach 1:
The system transitions from a static, fixed-margin approach to a dynamic approach where the target track is adjusted based on actual obstacle positions and parking section line detections. This allows the system to adapt to different parking scenarios while maintaining sufficient safety margins where needed.
Solution Approach 2:
The system applies different levels of conservatism to different parts of the parking maneuver. By detecting the positional relationship between obstacles and parking section lines, the system can locally adjust the target track parameters (turning radius, straight line length) to provide sufficient margin only where obstacles require it, while allowing more efficient paths in clear areas.
