Vehicle Illumination Layout for 360° Autonomous Mode Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic driving vehicle systems fail to effectively communicate their driving mode to other vehicles and pedestrians, particularly from the front, which can lead to safety concerns during interactions on public roads.
Innovation Solution
A vehicle illumination device that surrounds the vehicle's circumference, using an illumination control unit to set specific lighting states based on the vehicle's driving mode and environmental illuminance, ensuring that information about the automatic driving mode is visibly conveyed to others, preventing confusion and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an illumination device is installed on the front of the vehicle to display automatic driving information, then the information can be recognized by vehicles following behind, but the information cannot be visually recognized from the front of the vehicle
Solution Approach 1:
The illumination device is divided into multiple independent illumination units arranged around the vehicle's circumference. Each unit can be independently controlled to display different information, allowing the system to present automatic driving status from multiple directions including the front, where previously no illumination was provided.
Solution Approach 2:
The illumination device transitions from a single-direction (rear-facing) display to a multi-directional arrangement surrounding the vehicle. This spatial dimensionality change enables information to be visible from the front and all sides of the vehicle, not just from behind.
2Reliability
If the illumination unit is always on to ensure visibility of automatic driving mode, then safety is improved, but energy consumption increases
Solution Approach 1:
The illumination control unit dynamically adjusts the illumination state based on real-time driving mode changes and environmental conditions. The system transitions from static constant illumination to dynamic adaptive illumination, turning on specific illumination units only when needed based on the vehicle's operational state.
Solution Approach 2:
The system changes illumination parameters (on/off state, intensity) based on environmental illuminance levels and driving mode. In bright conditions or when not in automatic driving mode, the illumination is reduced or turned off, conserving energy while maintaining visibility when necessary.
