Vehicle Intersection Control via Opposing Lane Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems do not effectively manage the transition to an intersecting road when an opposing vehicle is present at an intersection, leading to potential delays or unsafe maneuvers.
Innovation Solution
A vehicle control apparatus and method that includes a road recognizer, a second-vehicle recognizer, and a driving controller, which assess the road layout and opposing vehicle's position to control steering and acceleration/deceleration, allowing the vehicle to safely proceed to the intersecting road by selecting an appropriate lane based on the presence of the opposing vehicle, even if it has entered a lane on the rear side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle waits for the opposing vehicle to clear the intersection before proceeding, then collision risk is reduced, but passage time increases and traffic flow efficiency deteriorates
Solution Approach 1:
The control system dynamically adjusts the vehicle's passage decision based on real-time detection of opposing vehicle position and lane entry status. When the opposing vehicle enters a rear-side lane, the system dynamically changes from a conservative waiting policy to an aggressive passage policy, allowing the vehicle to proceed through the intersection immediately.
Solution Approach 2:
The system continuously monitors the opposing vehicle's lane entry behavior through the lane recognizer and uses this feedback to adjust passage control. The feedback loop detects when the opposing vehicle has entered a rear-side lane and triggers the appropriate passage response, creating a closed-loop control system that adapts to changing traffic conditions.
2Productivity
If the vehicle enters the intersecting road when the opposing vehicle is present, then passage efficiency improves, but the risk of collision or unsafe maneuver increases
Solution Approach 1:
The system performs preliminary detection of the opposing vehicle's lane entry status before making the passage decision. By using the lane recognizer to detect in advance whether the opposing vehicle has entered a rear-side lane, the system prepares the passage control in advance, ensuring that passage is only permitted when safe conditions are predicted to exist.
3Reliability
If the vehicle strictly follows traditional intersection control rules and waits for opposing vehicles to clear, then safety is maintained, but excessive waiting occurs and traffic flow is disrupted
Solution Approach 1:
The system changes the control parameter from a fixed waiting rule to a dynamic decision based on opposing vehicle lane entry status. When the opposing vehicle enters a rear-side lane, the control parameter changes to permit passage, effectively adjusting the safety threshold based on the specific traffic situation rather than applying a uniform waiting rule.

AI summary
A vehicle control apparatus includes: a road recognizer that recognizes a road form around a vehicle; a second-vehicle recognizer that recognizes a state of another vehicle around the vehicle; and a driving controller that allows the vehicle to travel by controlling one or both of steering and acceleration/deceleration of the vehicle and that prevents, upon passing of the vehicle through an intersection, passing of the vehicle through the intersection based on a presence of the other vehicle recognized by the second-vehicle recognizer, wherein in a case where the driving controller recognizes, by the road recognizer, that a plurality of lanes are present in a road of a right/left turn destination of the vehicle and recognizes, by the second-vehicle recognizer, that the other vehicle, which was an opposing vehicle approaching from a direction opposing the vehicle, has entered a lane on a rear side in a view from the vehicle among the plurality of lanes in the road of the right/left turn destination, the driving controller continues an entry control to the road of the right/left turn destination of the vehicle.
