Vehicle Parking Detection via External Server Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control units have limited processing power and memory capacity, restricting their ability to accurately and efficiently detect and store data for parking space detection, especially for longer parking spaces that require more memory and complex calculations.
Innovation Solution
A method and system where vehicle-side sensors transmit measurement values to a vehicle-external server unit for evaluation, leveraging greater processing power and memory capacity to accurately detect and store parking spaces, allowing for real-time data collection and transmission of parking positions along streets or city districts, and providing this information to vehicles before they reach a location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement values are stored and processed in the vehicle's control unit, then parking space detection can be performed, but the limited processing power and memory capacity restrict accurate detection of longer parking spaces
Solution Approach 1:
The patent extracts the data processing function from the vehicle's control unit and relocates it to an external server. The control unit only collects measurement values from sensors and transmits them to the external server, which performs the complex evaluation and storage. This extraction resolves the contradiction by removing the memory capacity constraint from the vehicle system while maintaining detection accuracy.
Solution Approach 2:
The patent introduces an external server as an intermediary between the vehicle's sensor system and the parking space database. The server acts as a mediator that receives measurement values from multiple vehicles, evaluates parking space availability, and stores results for retrieval. This intermediary resolves the contradiction by providing unlimited processing power and memory capacity outside the vehicle's constrained environment.
2Measurement precision
If complex calculations are performed on the vehicle's control unit to detect parking spaces, then detection can be achieved, but the processing power is insufficient for accurate detection of longer parking spaces
Solution Approach 1:
The patent extracts the complex calculation and evaluation functions from the vehicle's control unit and transfers them to an external server. The control unit only performs simple data collection and transmission, while the server handles the computationally intensive tasks of evaluating measurement values and determining parking space availability. This resolves the processing power contradiction by moving computational demands to a system with unlimited resources.
3Speed
If parking space detection is performed using vehicle-side sensors and processing, then real-time detection is possible, but the limited resources prevent accurate detection of longer parking spaces requiring more memory
Solution Approach 1:
The patent extracts the memory-intensive evaluation and storage functions from the vehicle's control unit to an external server. The vehicle system maintains real-time detection capability by only performing sensor data acquisition and transmission, while the server handles the memory-intensive tasks of storing measurement values and evaluating parking spaces of any length. This resolves the contradiction by separating real-time data collection from resource-intensive data processing.

AI summary
A method for ascertaining a free parking position for a vehicle, in which at least one measurement value is ascertained by at least one vehicle-side sensor, the at least one ascertained measurement value is transmitted by a vehicle-side communication device of at least one vehicle to a vehicle-external server unit, the at least one ascertained measurement value is evaluated with respect to a free parking position by the vehicle-external server unit, and the evaluated at least one free parking position is provided in a retrievable manner on the vehicle-external server unit. A system for implementing the method is also described.
