Parking Position Selection Using Vehicle Geometry and Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parking systems for autonomous vehicles lack an efficient method to determine parking positions that minimize collisions with other vehicles and infrastructure during entry and exit operations, as they do not account for vehicle geometry and maneuverability parameters.
Innovation Solution
A method and device that ascertain a vehicle's geometry and maneuverability parameters to select an optimal parking position from multiple options in a parking lot, ensuring sufficient maneuvering space and minimizing the number of required maneuvers, by classifying vehicles as 'large' or 'small' based on these parameters and strategically positioning them to maximize available space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed or arbitrary parking position is selected for autonomous vehicles, then the parking operation can be simplified, but the likelihood of collision with already parked vehicles and infrastructure increases during entry and exit maneuvers
Solution Approach 1:
The system changes the parameter of parking position selection from fixed/arbitrary to dynamic and adaptive. By considering vehicle geometry parameters (length, width, height) and maneuverability parameters (turning radius, steering angle), the system selects optimal parking positions that accommodate each vehicle's specific characteristics, thereby reducing collision likelihood during maneuvers
Solution Approach 2:
The system performs preliminary assessment of vehicle geometry and maneuverability parameters before selecting a parking position. This advance planning allows the system to pre-determine safe entry and exit paths, avoiding collisions with already parked vehicles and infrastructure elements
2Reliability
If vehicle geometry and maneuverability parameters are considered for parking position selection, then collision likelihood is reduced, but the complexity of the parking system increases
Solution Approach 1:
The system enables vehicles to self-assess their own geometry and maneuverability parameters and communicate them to the parking management system. This self-service approach reduces the need for complex external measurement devices, as vehicles provide their own data for optimal parking position selection
Solution Approach 2:
The parking management system serves multiple functions: it manages parking positions, receives vehicle parameter data, performs collision risk assessment, and optimizes parking assignments. This multi-functionality consolidates complexity into a single centralized system rather than requiring separate specialized systems for each function
