Platoon Vehicle Distance Control for Cut-In Traffic Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic traveling vehicles face instability and platoon disruption when a moving body enters between the vehicle and the leading vehicle, causing the platoon to break and fail in maintaining stable traveling.
Innovation Solution
A vehicle equipped with detectors to identify potential entering moving bodies between itself and the preceding vehicle, and a controller that adjusts the inter-vehicle distance by accelerating or decelerating based on the detected distance to prevent entry and ensure stable platoon travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle stops traveling when a moving body enters between the vehicle and the leading vehicle, then safety is improved, but platoon stability deteriorates
Solution Approach 1:
The controller changes the inter-vehicle distance parameter dynamically based on the presence of moving bodies. When a moving body is detected in the detection area, the controller increases the inter-vehicle distance to prevent collision while maintaining platoon formation, rather than stopping the vehicle entirely.
2Stability of the object's composition
If the vehicle maintains a fixed inter-vehicle distance, then platoon formation is stable, but safety is reduced when moving bodies enter the area
Solution Approach 1:
The system transitions from a static inter-vehicle distance to a dynamic adjustment mechanism. The controller continuously monitors the detection area and adjusts the inter-vehicle distance in real-time based on the presence of moving bodies, allowing the system to adapt to changing conditions while maintaining overall platoon stability.
3Reliability
If the vehicle accelerates or decelerates based on moving body detection, then safety is improved, but control complexity increases
Solution Approach 1:
The controller implements a feedback mechanism where the detector continuously provides information about moving bodies in the detection area, and the controller responds by adjusting the inter-vehicle distance accordingly. This closed-loop control system automatically manages safety without requiring complex manual intervention or overly sophisticated control algorithms.

AI summary
The present invention provides a vehicle with which it is possible to realize stable platoon travel. This vehicle (100) travels autonomously by following a leading vehicle while maintaining a prescribed distance between vehicles, wherein the vehicle (100) has: a detection unit (110) that detects moving bodies present around the vehicle; and a control unit (160) that determines an entering moving body, among the moving bodies detected by the detection unit (110), that may enter an area between the vehicle and the leading vehicle, and causes the vehicle to accelerate or decelerate on the basis of the distance between the entering moving body and the area.
