Parking Base Station Data Segmentation for Valet Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fully automated valet parking systems, vehicles experience long waiting times in the entry area due to the need to transmit a large amount of data required for navigation from the starting position to the target position, which can lead to inefficiencies and reduced throughput.
Innovation Solution
A method and device that determine and transmit only the minimum amount of data needed for a vehicle to transition between base stations, using a digital transmission power map to optimize data transmission based on the transmission powers of each base station, ensuring that the vehicle receives only the necessary data for its immediate journey, thereby reducing waiting times and increasing throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all navigation data for the entire journey is transmitted to the vehicle at the entrance, then the vehicle has complete information for the full journey, but the transmission time increases causing long waiting times
Solution Approach 1:
The navigation data transmission is segmented into multiple portions corresponding to different base station radio ranges. The vehicle receives data for the first segment (from entrance to first base station boundary) before leaving the entrance area, then receives subsequent data segments from subsequent base stations. This divides the large data transmission task into smaller, manageable portions that can be transmitted quickly.
Solution Approach 2:
The system performs preliminary action by transmitting only the minimum necessary data portion that enables the vehicle to reach the next base station boundary, rather than waiting to transmit all data. This preliminary data transmission allows the vehicle to proceed immediately without waiting for complete navigation information.
2Reliability
If the vehicle waits for complete data transmission before leaving the entry area, then it ensures all necessary information is received, but the throughput of the parking lot decreases
Solution Approach 1:
The system applies partial action by transmitting only the sufficient portion of data needed for the vehicle to reach the next base station boundary, rather than transmitting all possible navigation data. This partial data transmission is sufficient for the immediate next step, enabling the vehicle to proceed without delay while maintaining reliability for the current segment.
3Productivity
If the system transmits data based on actual transmission power conditions, then data transmission efficiency improves, but the system complexity increases due to digital transmission power map requirements
Solution Approach 1:
The digital transmission power map is created in advance through preliminary measurements and characterizations of each base station's actual transmission power in different directions. This pre-computed map allows the system to efficiently determine appropriate transmission parameters without real-time complexity, as the power characteristics are already known and stored.

AI summary
The invention relates to a method for operating a parking space, within which multiple base stations are arranged, a) wherein a minimum data amount of data required from a vehicle for travel to the parking space is determined in such a way that, based on the data corresponding to the minimum data amount, the vehicle leaves a radio range of a first base station and can travel into radio range of a second base station, b) wherein the first base station transmits the determined minimum data amount of data to the vehicle located in the radio range of the first base station so that, based on the data, the vehicle can leave the radio range of the first base station and travel into the radio range of the second base station. The invention additionally relates to a corresponding device, a corresponding parking system, and a computer program.
