Light Irradiation Control for Vehicle Platoon Configuration Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light-irradiation control systems for autonomous vehicle platoons fail to effectively inform surrounding drivers of changes in vehicle configuration due to mergence, separation, or other dynamic changes, leading to potential safety issues and increased control burdens.
Innovation Solution
A light-irradiation control apparatus and method that includes an irradiation controller, a vehicle-platoon-information acquiring unit, and a controller to dynamically adjust light modes based on vehicle platoon configuration changes, switching between steady-state and transition modes to indicate merging or leaving vehicles, thereby enhancing driver awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the vehicle platoon uses a steady-state light irradiation mode to indicate vehicle presence, then the driver awareness of the platoon is maintained, but the driver awareness of configuration changes (mergence/separation) is not effectively communicated
Solution Approach 1:
The light irradiation system transitions from a static steady-state mode to a dynamic transition mode when platoon configuration changes occur. The controller detects mergence or separation events and switches the irradiation pattern accordingly, enabling the system to adapt its behavior based on real-time platoon state changes while maintaining a simple underlying hardware structure
Solution Approach 2:
The system changes the light irradiation parameters (such as intensity, pattern, or temporal characteristics) between steady-state and transition modes to encode different platoon configuration states. By modifying light parameters rather than adding hardware components, the system communicates configuration changes effectively without increasing device complexity
2Adaptability or versatility
If the vehicle platoon frequently changes configuration through mergence and separation, then the system adaptability is improved, but the safety risk due to undetected changes by surrounding drivers increases
Solution Approach 1:
The system implements a feedback mechanism where the light irradiation pattern provides visual feedback to surrounding drivers about platoon configuration changes. When mergence or separation occurs, the transition mode light pattern serves as immediate visual feedback, allowing surrounding drivers to perceive and respond to configuration changes in real-time, thereby maintaining safety despite frequent platoon reconfigurations
Solution Approach 2:
The system utilizes changes in light characteristics (such as color, intensity, or pattern) to signal different platoon states. By encoding configuration change information through light parameter variations, the system provides clear visual cues to surrounding drivers, enabling them to distinguish between steady-state operation and dynamic reconfiguration events

AI summary
An object is to provide a light-irradiation technique that are capable of making the driver of a vehicle around a vehicle platoon aware of changes in the vehicle configuration of the vehicle platoon. During no changes in the vehicle configuration of a vehicle platoon, a controller performs control in such a manner that an irradiation device of the vehicle casts light in a steady-state mode common in the vehicle platoon. In a process where the vehicle merges with another of the vehicle alone or another of the vehicle platoon, the controller performs control in such a manner that the irradiation device of the merging vehicle casts light in a transition mode. In a process where the vehicle leaves the vehicle platoon, the controller performs control in such a manner that the irradiation device of the leaving vehicle casts light in the transition mode.
