Parking Lot Mapping System Using Vehicle Position Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle navigation systems lack complete and up-to-date map data for parking lots, as these areas frequently change configurations and are often inadequately represented in existing map data, hindering effective path planning.
Innovation Solution
A remote server-based parking lot mapping system that collects and processes vehicle position data to create and update maps of parking lots by determining entry and exit points, routes, and parking spots based on transmitted data from vehicles, using a combination of GPS, sensors, and controllers to infer and store this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If map data for parking lots is not updated frequently, then the complexity of the mapping system is reduced, but the reliability of path planning deteriorates due to incomplete or outdated data
Solution Approach 1:
The system enables parking lots to self-map by automatically collecting vehicle position data from multiple vehicles and using this accumulated data to generate and update maps without requiring manual intervention. The electronic controller determines vehicle positions and routes autonomously, and the map is continuously updated based on accumulated vehicle data, allowing the system to maintain itself
Solution Approach 2:
The mapping system serves multiple functions: it collects vehicle position data, determines vehicle routes, identifies parking spots, generates maps, and continuously updates the map data. This multi-functional approach consolidates what would otherwise require separate systems into a single integrated solution that improves reliability while managing complexity
2Adaptability or versatility
If manual mapping of parking lots is performed, then the initial map data can be obtained, but the adaptability to frequent configuration changes deteriorates
Solution Approach 1:
The system continuously collects feedback from vehicle position data as vehicles traverse the parking lot. This feedback loop allows the system to detect changes in parking lot configuration and automatically update the map data, making the system adaptable to frequent changes without requiring manual remapping
Solution Approach 2:
The mapping system operates continuously by constantly collecting vehicle position data and updating the map in real-time. This continuous operation ensures the map remains current with parking lot configurations, providing adaptability without the need for periodic manual updates that would reduce productivity
3Measurement precision
If comprehensive vehicle position data is collected from all vehicles, then the measurement precision of parking lot routes and spots is improved, but the loss of time for data processing increases
Solution Approach 1:
The system performs preliminary actions by continuously collecting and accumulating vehicle position data in the background as vehicles use the parking lot. This ongoing data collection prepares the map data in advance, so when updates are needed, the information is already accumulated and ready for processing, reducing the time loss associated with data gathering
Data Source
AI summary
A parking lot mapping system includes a server. The server is remote from a plurality of vehicles, and includes a receiver, an electronic controller and a storage device. The receiver is configured to receive data transmitted from the vehicles, the data including a route traveled and a stopping position of each of the vehicles. The electronic controller is configured to determine that each vehicle has entered a parking lot, and form a map of the parking lot including parking lot routes and parking spots based on accumulation of the data including the stopping position of each vehicle and the route traveled by each of the vehicles after determination that each vehicle vehicles has entered the parking lot. The storage device is configured to store the map of the parking lot.
