Autonomous Vehicle Competition Control via Dynamic Priority Arbitration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In situations where multiple autonomous vehicles attempt to enter the same space simultaneously, there is a risk of inefficient entry failures due to the lack of an arbitrator to control competition, leading to potential collisions and traffic inefficiencies.
Innovation Solution
An apparatus and method for controlling autonomous vehicle competition, which includes determining whether an autonomous vehicle can enter a competitive space, calculating waiting times based on priority and number of entries, and controlling the vehicle to re-attempt entry after a determined waiting period, using devices such as cameras and sensors to assess the surrounding situation and predict collision risks.

Engineering Contradiction Analysis
1Extent of automation
If multiple autonomous vehicles attempt to enter the same competitive space simultaneously without an arbitrator, then each vehicle can pursue its own driving goal independently, but entry failures are repeated and traffic efficiency deteriorates
Solution Approach 1:
The patent introduces a competition control device as an intermediary mechanism that mediates between multiple autonomous vehicles competing for the same space. This device receives entry requests from multiple vehicles, determines priority based on predefined criteria (such as right-of-way rules, vehicle positions, and speeds), and grants entry permission to the highest-priority vehicle while denying or delaying entry to others, thereby resolving conflicts without sacrificing autonomous decision-making capabilities
Solution Approach 2:
The system performs preliminary determination of entry priority before actual entry attempts. The competition control device pre-establishes the hierarchy of vehicles based on their characteristics and positions, and vehicles are granted entry permission in advance based on this predetermined priority order, preventing simultaneous conflicting entries and reducing repeated entry failures
2Reliability
If autonomous vehicles use determination references to control competition situations, then collision risk is reduced, but the complexity of the control system increases
Solution Approach 1:
The patent employs parameter-based priority determination where vehicles are assigned priority levels based on measurable parameters such as position coordinates, speed values, distance to intersection, and vehicle type. The competition control device compares these parameters objectively to determine entry priority, providing a reliable and systematic method for conflict resolution that avoids complex behavioral algorithms while maintaining high safety standards
3Reliability
If vehicles wait for competition waiting time before re-attempting entry, then collision risk is reduced, but the time required to complete the entry action increases
Solution Approach 1:
The competition waiting time is not a fixed value but a dynamic parameter that adjusts based on the priority of the vehicle and the characteristics of the competition situation. High-priority vehicles experience shorter or no waiting periods, while lower-priority vehicles are assigned longer waiting times. This dynamic adjustment ensures safety by preventing simultaneous entries while minimizing unnecessary time losses for vehicles that are entitled to priority access

AI summary
An apparatus for controlling competition of an autonomous vehicle may include an autonomous drive determination device that determines whether the autonomous vehicle is capable of entering a competitive space in a situation where the autonomous vehicle is required to move into the competitive space during autonomous driving, a vehicle control device that controls the autonomous vehicle such that the autonomous vehicle enters the competitive space when the autonomous vehicle is capable of entering the competitive space, and when the autonomous vehicle fails to enter the competitive space after attempting to enter the competitive space, a vehicle competition control device that controls such that the attempt to enter the competitive space is held for a first competition waiting time.
