Accessible Vehicle Parking with Biased Positioning Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in parking vehicles is to automatically guide and park them in a manner that provides sufficient space for occupants to enter and exit, considering the vehicle's profile and accessibility requirements, while navigating through crowded spaces and potential obstacles.
Innovation Solution
A system that creates a vehicle accessibility profile, ranks parking locations based on this profile, and uses onboard sensors to adjust the vehicle's position within the parking space, potentially requesting adjacent vehicles to move if necessary, to ensure optimal accessibility and clearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle is parked closer to maximize space utilization, then productivity is improved, but accessibility for occupants deteriorates
Solution Approach 1:
The system applies different quality requirements to different regions of the parking space. The accessible side requires additional clearance space for ramps and occupant movement, while the opposite side can be positioned closer to maximize overall space utilization. This local differentiation resolves the contradiction by allowing tight parking overall while maintaining accessibility where needed.
Solution Approach 2:
The system performs preliminary assessment of accessibility requirements before finalizing the parking position. By evaluating the accessibility profile and determining biasing needs in advance, the system can pre-calculate the optimal parking position that satisfies both space utilization and accessibility requirements, rather than adjusting after parking.
2Ease of operation
If the vehicle requires additional clearance space for accessibility equipment, then accessibility is improved, but the area occupied by the vehicle increases
Solution Approach 1:
The system applies additional clearance requirements locally only to the side of the vehicle where accessibility equipment (ramps, lifts) is installed, rather than increasing clearance uniformly around the entire vehicle. This localized approach maintains accessibility while minimizing the total area occupied.
Solution Approach 2:
The system dynamically adjusts the required clearance space based on the specific accessibility profile and equipment configuration. The biasing distance is calculated adaptively according to the actual accessibility needs, allowing the parking space requirement to vary rather than being fixed, thus optimizing space utilization while maintaining accessibility.
3Ease of operation
If the vehicle autonomously adjusts its parking position to ensure accessibility, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system enables the vehicle to autonomously determine and adjust its own parking position based on its accessibility profile and sensor data about the parking environment. The vehicle self-calculates the required biasing distance and self-adjusts its position without requiring external intervention or complex manual coordination, improving ease of operation while managing complexity through self-service automation.

AI summary
A system and method for vehicle accessibility parking including creating an accessibility profile associated with a vehicle and also creating a profile of the vehicle. Based on the profile of the vehicle and the accessibility profile, one or more parking locations are identified. The method includes a ranking, based on the profile of the vehicle and the accessibility profile, the identified one or more parking locations. The vehicle is then routed to a highest ranking identified one or more parking locations. Once routed, a sensor in the vehicle determines if a biasing of the vehicle in a parking space in the highest ranking identified one or more parking locations is required. Based on the biasing, an adjusting of a target parking position for the vehicle in the parking space is performed.
