Autonomous Vehicle Intersection Priority Control in Parking Lots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face collisions or delayed passage at intersections within parking lots due to overlapping movement paths without a standard for vehicle prioritization.
Innovation Solution
A server communicates with vehicles to generate and transmit priority information, adjusting driving lines for collision avoidance and managing entry and exit paths based on transit times and order, ensuring efficient passage through intersections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple autonomous vehicles enter an intersection area within a parking lot without a prioritization standard, then vehicles can move freely, but collisions occur or passage is delayed
Solution Approach 1:
A server acts as an intermediary between multiple autonomous vehicles at the intersection. The server receives driving information from each vehicle, generates priority information based on predetermined criteria (entry order, transit time, vehicle type), and transmits control information to each vehicle. This centralized mediation resolves the contradiction by coordinating vehicle movements to prevent collisions while maintaining operational freedom.
Solution Approach 2:
The system changes the parameter of vehicle priority dynamically based on multiple factors including entry order into the intersection, predicted transit time through the intersection, and vehicle type. By adjusting priority parameters in real-time, the system ensures safe passage while maintaining efficient traffic flow.
2Reliability
If a server generates and transmits priority information to multiple vehicles, then collision avoidance is improved, but system complexity increases
Solution Approach 1:
Each autonomous vehicle autonomously receives and processes the priority information and control information transmitted by the server. The vehicles' own control systems execute the prioritization logic locally, meaning each vehicle serves itself by implementing the server's directives without requiring complex centralized control mechanisms beyond information transmission.
Solution Approach 2:
The server simplifies the overall system complexity by acting as a centralized intermediary that handles all priority calculations and decision-making. Instead of requiring complex inter-vehicle communication and negotiation protocols, the server centralizes the complexity in one location, transmitting simple priority directives to each vehicle.
3Productivity
If vehicles follow predetermined priority rules at intersections, then passage efficiency is improved, but flexibility in response to dynamic conditions decreases
Solution Approach 1:
The priority information is not static but dynamically determined based on real-time conditions. The server calculates priority based on entry order, predicted transit time, and vehicle type for each specific situation. This dynamic approach maintains high passage efficiency through structured priority rules while adapting to varying traffic conditions and vehicle characteristics.
Solution Approach 2:
The system changes priority parameters dynamically based on multiple factors including entry order into the intersection, predicted transit time through the intersection, and vehicle type. This allows the system to maintain efficient structured passage while adapting to different dynamic conditions.

AI summary
An autonomous driving system includes a server, and a plurality of vehicles configured to communicate with the server. The server is configured to obtain driving information on each of the plurality of vehicles entering an intersection area within a parking lot, generate priority information on each of the plurality of vehicles based on the driving information on each of the plurality of vehicles, and transmit control information including the priority information to each of the plurality of vehicles based on the priority information so that the plurality of vehicles pass through the intersection area.
