Parking Garage Navigation Using Geometric Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking systems in garages fail to geographically localize free parking spaces, making it difficult for vehicles to quickly find available spaces, leading to inefficiency and discomfort for drivers.
Innovation Solution
A parking system that uses an evaluation and control unit with a transceiver and distance sensors to receive and update information about parking garage geometry and occupancy status, allowing vehicles to automatically navigate to free spaces and provide navigation instructions, thereby recognizing only correct parking spaces and ignoring irrelevant areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If parking spaces are measured using distance sensors and transmitted to a central database, then the number of free parking spaces can be displayed, but the free parking spaces cannot be geographically localized
Solution Approach 1:
The system divides the parking garage into individual parking space segments, each with unique geometric coordinates. Distance sensors in vehicles measure and identify specific parking spaces by comparing measured distances with stored geometric data of individual spaces, enabling precise geographic localization rather than just counting available spaces.
Solution Approach 2:
Geometric data of the parking garage serves as an intermediary between the distance sensors and the central database. The geometric data contains coordinate information of all parking spaces, allowing the system to translate distance measurements into specific geographic locations and transmit this localized information to vehicles.
2Productivity
If all parking spaces are used including corners and restricted areas, then parking capacity increases, but incorrect areas are identified as valid parking spaces
Solution Approach 1:
Different areas of the parking garage are assigned different qualities or statuses in the geometric data. Valid parking spaces have specific geometric characteristics and accessibility parameters, while corners and restricted areas have different properties. The system evaluates each area's local characteristics to determine if it qualifies as a valid parking space.
Solution Approach 2:
The system changes evaluation parameters when identifying parking spaces, considering not just distance measurements but also geometric coordinates, accessibility parameters, and area characteristics. By adjusting which parameters are considered valid for parking space identification, the system can accurately distinguish usable spaces from restricted areas.
3Loss of time
If vehicles manually search for parking spaces, then drivers have full control, but parking time and driver workload increase
Solution Approach 1:
The parking system provides self-service by automatically calculating optimal routes to free parking spaces using the vehicle's current position and the geographic locations of available spaces. The system independently performs route optimization and navigation guidance without requiring driver intervention in the calculation process, reducing both time and operational complexity.
Solution Approach 2:
The system performs preliminary actions by pre-calculating routes to multiple free parking spaces before the driver needs to park. When a vehicle enters the parking garage, the system has already identified available spaces and prepared navigation instructions, eliminating the need for manual searching and reducing parking search time.
