Autonomous Parking Offset Control Near Pillars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous parking systems often cause interference between vehicle doors or side mirrors and pillars when parking next to them, leading to inconvenience and potential damage, as they do not adequately consider the driver's preference for parking close to pillars for convenience.
Innovation Solution
An apparatus and method for controlling autonomous parking that includes a sensor unit, storage for driver tendency information, and a controller to search for available parking spaces, determine pillar proximity, and set parking offsets to avoid interference by adjusting the parking target position based on driver input and sensor data, ensuring the door and side mirror do not collide with the pillar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the autonomous parking system parks the vehicle close to the pillar for convenience, then the ease of operation is improved, but the door and side mirror may collide with the pillar causing damage
Solution Approach 1:
The system performs preliminary detection of the pillar position using sensors before the parking maneuver, and pre-calculates the safe parking offset distance to prevent collision. This advance preparation allows the vehicle to park close to the pillar while maintaining safety margins.
Solution Approach 2:
The system dynamically adjusts the parking offset parameter based on detected pillar position, vehicle type, and door opening requirements. By changing the offset parameter, the system optimizes the balance between parking convenience and collision prevention.
2Reliability
If the autonomous parking system increases the parking offset to avoid collision, then the reliability is improved, but the convenience of getting on and off deteriorates
Solution Approach 1:
The system optimizes the parking offset parameter to achieve the minimum safe distance that prevents collision while maximizing convenience. This parameter optimization ensures reliability without excessive reduction in ease of operation.
Solution Approach 2:
The system applies different offset strategies for different vehicle components - the door offset is calculated separately from the side mirror offset based on their respective collision risks and functional requirements, allowing optimized protection for each component.
3Device complexity
If the autonomous parking system uses fixed parking offset values, then the device complexity is reduced, but the adaptability to different parking scenarios deteriorates
Solution Approach 1:
The system uses adjustable offset parameters that can be modified based on parking scenario, vehicle type, and detected pillar position. This parameter-based approach provides adaptability without requiring complex restructuring of the parking control algorithm.
Solution Approach 2:
The system pre-stores multiple offset values corresponding to different vehicle types and parking scenarios. During autonomous parking, the appropriate pre-stored offset is selected based on the current situation, providing adaptability without real-time complex calculations.
