Parking Facility Server Map Segmentation for Autonomous Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems for autonomous vehicles in parking facilities lack digital maps, making navigation difficult and inefficient, and require significant memory and bandwidth for data transmission.
Innovation Solution
A server-based system that stores digital maps of parking facilities, processes target positions, and transmits only necessary sections of the map via a communication network to the vehicle, reducing memory requirements and data volume, allowing for efficient autonomous navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the entire digital map is transmitted to the vehicle via communication network, then the vehicle has complete navigation information available, but the data transmission time and memory requirements become excessively large
Solution Approach 1:
The digital map is divided into multiple sections corresponding to different areas or floors of the parking facility. Only the relevant map section for the current navigation task is transmitted to the vehicle, rather than the entire map. This segmentation reduces data transmission time while providing sufficient navigation information for the specific route.
Solution Approach 2:
The system extracts and transmits only the necessary portion of the digital map that corresponds to the route from the current position to the target parking space. This extraction principle eliminates unnecessary data transmission, reducing both transmission time and memory requirements while maintaining complete navigation capability for the intended route.
2Loss of information
If the entire digital map is stored in the vehicle, then complete navigation information is available, but the memory requirements become excessively large
Solution Approach 1:
The digital map is segmented into multiple sections, and only the relevant section for the current navigation task is stored in the vehicle's memory. This segmentation approach significantly reduces the memory capacity required while ensuring that complete navigation information for the intended route is available.
Solution Approach 2:
The system extracts only the necessary map section corresponding to the navigation route and stores it in the vehicle. This extraction principle eliminates the need to store the entire digital map, reducing memory requirements from potentially gigabytes to much smaller sizes while maintaining complete navigation capability for the specific route.
3Loss of time
If high bandwidth is allocated for map transmission, then complete digital map can be transmitted quickly, but the system complexity and infrastructure requirements increase
Solution Approach 1:
Instead of transmitting the entire digital map (excessive action), the system transmits only the necessary portion of the map required for navigation to the target position. This partial transmission approach achieves adequate navigation capability with minimal data transfer, reducing the required bandwidth and simplifying communication infrastructure requirements.
