UWB Parking Assistance for Autonomous Space Finding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large parking lots and multi-storey car parks, finding and accessing suitable parking spaces is challenging due to reduced visibility, varying space sizes, and the need for manual guidance, which complicates the parking process for vehicles like minibuses.
Innovation Solution
A comfort system utilizing UWB module units for communication and detection, enabling autonomous navigation to free parking spaces by exchanging data with external devices and using UWB technology for precise location determination and obstacle avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual guidance systems are used in parking garages, then parking space availability can be indicated, but the complexity of the parking process increases and automation is reduced
Solution Approach 1:
The vehicle's own sensors and processing systems are used to detect parking spaces and guide the vehicle, eliminating the need for external attendants or complex centralized guidance systems. The vehicle performs the guidance function itself through its detection and navigation systems.
Solution Approach 2:
Manual mechanical guidance systems are replaced with electronic sensor-based detection and automated navigation systems. The patent uses optical, acoustic, or electromagnetic sensors to detect parking spaces and electronic control systems to automate the guidance process.
2Adaptability or versatility
If parking space information is provided without vehicle-specific data, then information exchange is simplified, but the suitability of parking spaces for specific vehicles cannot be determined
Solution Approach 1:
The vehicle's dimensions and characteristics are pre-stored in its control system before entering the parking garage. This allows the vehicle to automatically compare its specifications with available parking space dimensions and selectively identify suitable spaces without complex real-time data exchange.
Solution Approach 2:
A standardized data interface serves as an intermediary between the vehicle's detection system and the parking space information system. This interface enables efficient data exchange by using predefined parameters for vehicle dimensions and parking space characteristics, simplifying the matching process.
3Productivity
If the vehicle searches for parking spaces at reduced speeds, then energy consumption is reduced, but the time required to find and access parking spaces increases
Solution Approach 1:
The detection system operates at full capability to identify all available parking spaces, but the vehicle only navigates to the most suitable one. This partial action approach allows comprehensive detection without requiring continuous high-speed operation throughout the entire parking process.
Solution Approach 2:
The system continuously monitors detection results and provides feedback to adjust the search strategy. When parking spaces are detected, the system feedback-controls the vehicle's navigation to guide it directly to the selected space, optimizing the balance between search thoroughness and energy consumption.
