Mobile Body Merge Control Around Regulation Body Boundaries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile body control systems struggle to execute appropriate movement control in merging areas where regulation bodies are present, leading to potential interference between mobile bodies and discomfort for occupants.
Innovation Solution
A mobile body control device that includes a detector for acquiring positions of mobile bodies and regulation bodies, a distance calculator to determine distances between mobile bodies and regulation bodies, and a movement controller to execute movement control by accelerating or decelerating mobile bodies based on these distances, ensuring appropriate movement control in merging areas with regulation bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If movement control is executed to avoid interference between mobile bodies in merging areas, then traffic safety is improved, but occupant comfort deteriorates due to unnecessary control actions in regions where lane change is regulated
Solution Approach 1:
The control system applies different control strategies based on the local road environment. When a regulation body is detected in the merging area, the system switches to a first control pattern that prioritizes safety by preventing lane changes. When no regulation body is present, it switches to a second control pattern that prioritizes comfort by allowing smooth merging. This local adaptation resolves the contradiction by matching control behavior to local conditions.
Solution Approach 2:
The movement control system dynamically adjusts its behavior based on real-time detection of regulation bodies. The controller transitions between different control patterns (first pattern with regulation body, second pattern without) depending on the detected environment. This dynamic adaptation allows the system to optimize both safety and comfort according to actual road conditions rather than using a fixed control strategy.
2Reliability
If movement control is continuously executed in merging areas, then interference between mobile bodies is reduced, but device complexity increases due to additional detection and control logic
Solution Approach 1:
The system performs preliminary detection of regulation bodies in the merging area before executing movement control. By detecting the presence or absence of regulation bodies in advance, the system can pre-determine which control pattern to apply, simplifying the control logic structure and avoiding complex real-time decision-making during the control execution phase.
Solution Approach 2:
The control system uses feedback from the detection unit that monitors regulation bodies and mobile body positions. This feedback mechanism allows the controller to adjust control patterns based on actual system state and environmental conditions, creating a closed-loop control system that maintains reliability while managing complexity through structured feedback processing.

AI summary
A mobile body control device includes, a mobile body detector configured to acquire a position of a first mobile body and a position of a second mobile body, a regulation body detector configured to detect a position of a regulation body, a distance calculator configured to acquire a first distance from the first mobile body to the second mobile body and a second distance from the first mobile body to an end of the regulation body, and a movement controller configured to execute movement control of at least one of the first mobile body and the second mobile body. The movement controller is configured to execute the movement control in a case where the first distance is equal to or more than the second distance, and not to execute the movement control in a case where the first distance is less than the second distance.
