Parking Energy Assessment for Automatic Valet Vehicle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale parking lots, vehicles with insufficient energy may become stuck, causing congestion and interfering with the entry and exit of other vehicles, especially in automatic valet parking systems where vehicles are unmanned.
Innovation Solution
A vehicle control device that calculates the remaining energy of a vehicle, acquires parking lot information, predicts travel speed and time, calculates the required energy for entry and exit, and determines parking availability based on these factors to prevent vehicles from becoming stuck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicles are automatically driven and parked in large-scale parking lots, then parking convenience is improved, but the risk of vehicles becoming stuck due to insufficient energy increases
Solution Approach 1:
The system performs preliminary energy assessment before vehicle entry into the parking lot. The calculation unit computes the required energy amount based on map information and predicts traveling speed and movement time, then compares this with the vehicle's actual remaining energy. This preliminary check prevents vehicles with insufficient energy from entering, thereby avoiding the risk of vehicles becoming stuck while maintaining automatic parking convenience.
2Adaptability or versatility
If vehicles with insufficient energy are allowed to enter the parking lot, then entry flexibility is improved, but congestion and interference with other vehicles occurs
Solution Approach 1:
The system applies preliminary anti-action by preventing vehicles with insufficient energy from entering the parking lot in the first place. The control unit receives the required energy amount and actual remaining energy, then prohibits entry when the remaining energy is insufficient. This preemptive measure eliminates the potential harmful effect of vehicles becoming stuck and causing congestion, while still allowing flexible entry for vehicles with adequate energy.
3Quantity of substance
If the parking lot size is increased to accommodate more vehicles, then parking capacity is improved, but the traveling distance and energy consumption increase
Solution Approach 1:
The system performs preliminary calculation of the required energy amount based on the specific parking lot map information and vehicle route before entry. By comparing this pre-calculated required energy with the vehicle's actual remaining energy, the system ensures that only vehicles with sufficient energy for the specific distance in larger parking lots are allowed to enter, thereby accommodating increased parking capacity without causing energy insufficiency problems.
