Vehicle Park Assist Using Virtual Segment Intersection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art automatic parking systems fail to accurately map positions of vehicles with respect to small or tight parking spots, leading to inefficiencies in vehicle alignment and parking maneuvers.
Innovation Solution
A vehicle equipped with sensors and processors that load a stored parking spot, map the surrounding area, intersect virtual segments with physical boundaries, compare current and desired headings, and automatically adjust the vehicle's steering to align with the parking spot, enabling precise positioning and parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If prior art automatic parking systems are used, then the system structure is simple, but the positioning accuracy in tight parking spots is poor
Solution Approach 1:
The patent divides the parking spot mapping into multiple virtual segments (first virtual segment, second virtual segment, etc.) that correspond to different sensor detection zones. Each segment is independently processed and intersected with physical boundaries, enabling precise positioning in tight spaces through segmented spatial analysis.
Solution Approach 2:
The patent introduces virtual segments as a dimensional abstraction layer between sensor data and physical parking spots. By creating a virtual mapping dimension that intersects with physical boundaries, the system achieves accurate positioning without requiring complex direct sensor-to-position calculations.
2Manufacturing precision
If virtual mapping and sensor data processing are implemented, then positioning accuracy improves, but computational complexity increases
Solution Approach 1:
The patent pre-divides the parking spot into multiple virtual segments before executing the parking maneuver. This preliminary segmentation allows the system to process and intersect virtual segments with physical boundaries in a structured manner, reducing the computational complexity of real-time positioning calculations.
Solution Approach 2:
The virtual segments act as an intermediary between sensor data and the desired parking position. By introducing this intermediate virtual mapping layer, the system simplifies the complex direct calculation of vehicle position and orientation, enabling precise alignment through virtual-physical intersection operations.
