Vehicle Merge Determination Using Gap Creation on Main Roads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving technologies face challenges in ensuring safe and smooth merging of vehicles from a side lane into a main lane, particularly when drivers have low skills, which can lead to congestion and safety issues.
Innovation Solution
A determination device and method that utilize vehicle-to-vehicle communication to assess the state of both lanes and adjust the acceleration of vehicles on the main lane to create a safe space for merging vehicles, considering factors like driver skill and vehicle attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vehicle on the side lane merges into the main lane, then the vehicle can enter the main lane, but congestion on the side lane may occur and safety may be compromised
Solution Approach 1:
The system performs preliminary determination of merging safety before the actual merging action occurs. The determination device assesses whether it is safe for the second moving object to merge into the first road by evaluating the traveling states of multiple vehicles and the merging vehicle's attributes, ensuring safety is verified in advance rather than reactively
Solution Approach 2:
The system continuously monitors the traveling states of vehicles on both the main lane and side lane, and uses this feedback information to dynamically determine merging safety. The determination device receives updated state information and adjusts its assessment based on real-time conditions, including vehicle speeds, intervehicular distances, and merging vehicle attributes
2Reliability
If a vehicle merges into the main lane without considering acceleration of main lane vehicles, then merging can occur, but the merging may not be smooth and safety cannot be ensured
Solution Approach 1:
The determination process is segmented into distinct evaluation components: assessing the traveling state of reference vehicles on the main lane, evaluating the traveling state of vehicles ahead and behind the reference vehicle, analyzing the merging vehicle's attributes and state, and determining acceleration requirements. This segmentation allows each aspect to be evaluated systematically
Solution Approach 2:
The system calculates the required acceleration of the reference vehicle before the merging action occurs. By determining in advance how much acceleration is needed to create a safe merging gap, the system ensures both safety and smoothness of the merging operation without requiring complex real-time adjustments during the actual merge

AI summary
Provided is a determination device capable of safely and reliably causing a vehicle on a side road to enter and merge into a main road when merging into the main road. Information is acquired that indicates the vehicle status of vehicles CA, etc., and vehicles Ca, etc., that are traveling on a side road SR that merges with a main road MR on which the vehicles CA, etc., are traveling. When, on the basis of said information, an intervehicular space is to be formed between the vehicles CA, etc., that will make it possible for a vehicle Ca, etc., to enter, the vehicles CA, etc., are caused to form an interval on the basis of the acceleration applied to each of the vehicles CA, etc., and the entering vehicle Ca, etc., is allowed to move to a position in the intervehicular space.
