Parking Space Detection via Demand-Adaptive Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for determining unoccupied street parking spaces face inefficiencies due to redundant information reports from road users, leading to bandwidth wastage and increased processing loads, as well as challenges in maintaining accurate data collection.
Innovation Solution
A method where a central instance determines demand for reports from multiple vehicles and selectively suppresses redundant information transmission, using wireless signals to manage reporting frequency and reduce environmental scanning stress, ensuring optimal bandwidth utilization and accurate data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all second motor vehicles continuously report parking space information to the central instance, then data completeness and accuracy are improved, but bandwidth consumption and processing load increase significantly
Solution Approach 1:
The system dynamically adjusts the reporting behavior of second motor vehicles based on real-time demand signals from the central instance. When parking space information is scarce, the central instance requests reports from more vehicles; when information is sufficient, it reduces reporting requirements. This dynamic adaptation resolves the contradiction by making the system flexible rather than static.
Solution Approach 2:
The central instance implements a feedback mechanism where it evaluates the sufficiency of received parking space information and sends control signals back to second motor vehicles to adjust their reporting behavior. This closed-loop feedback system allows the central instance to maintain data accuracy while optimizing bandwidth usage based on actual information needs.
2Loss of information
If all second motor vehicles continuously scan and report environmental data, then information availability is improved, but processing load on board the second motor vehicle increases
Solution Approach 1:
The system allows second motor vehicles to operate autonomously in scanning and reporting mode without continuous central control. Vehicles self-manage their scanning and reporting activities based on received demand signals, reducing the need for complex centralized coordination and lowering individual vehicle processing loads while maintaining information availability.
Solution Approach 2:
Instead of requiring all second motor vehicles to continuously scan and report, the system implements partial action where only a subset of vehicles are activated to report at any given time, based on central instance demand. This reduces the overall processing load across the network while still gathering sufficient information to maintain data availability.
3Measurement precision
If environmental scanning is performed continuously by all second motor vehicles, then detection accuracy is improved, but environmental stress from electromagnetic waves and ultrasonic vibrations increases
Solution Approach 1:
The system replaces continuous environmental scanning with periodic scanning triggered by demand signals from the central instance. Second motor vehicles scan their environment only when requested, rather than continuously, which maintains detection accuracy when needed while significantly reducing cumulative environmental stress from repeated electromagnetic and ultrasonic emissions.

AI summary
A street parking space for a first motor vehicle is located within a predefined area. A method for determining an unoccupied street parking space includes steps of scanning environmental data of a second motor vehicle in the predefined area; determining an item of information regarding an unoccupied parking space in the area of the second motor vehicle on the basis of the environmental data; and reporting the item of information to a central instance. The central instance determines a demand for reports in the area on the basis of received information from a plurality of second motor vehicles, and suppresses further reports from a second motor vehicle as a function of the demand.
