Vehicle Side Display Mode Switching for Traffic Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information providing devices struggle to effectively display information to passengers while minimizing the influence on nearby vehicles, leading to inadequate information visibility and understanding due to restricted display settings for traffic safety.
Innovation Solution
An information providing device equipped with a display unit on the side surface of a vehicle, a detection unit that sets a broader detection area, and a control unit that switches between main and sub display modes or stops the display based on the proximity of nearby vehicles, reducing light intensity and color changes to minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display unit displays information with high light intensity towards the outside of the vehicle, then the information visibility to passengers is improved, but the influence on nearby vehicles travelling within the predetermined area increases
Solution Approach 1:
The display unit dynamically changes its light emission characteristics based on the detected position and movement of nearby vehicles. When a vehicle is detected in the predetermined area, the display unit switches from a first light emission state (high intensity for visibility) to a second light emission state (reduced intensity or turned off to minimize influence on nearby vehicles). This dynamic adjustment resolves the contradiction by making the light intensity adaptive rather than fixed.
Solution Approach 2:
The system changes the parameters of light emission (intensity, color, or emission state) based on the operational context. The control unit adjusts the light emission parameters of the display unit according to the presence of nearby vehicles, transforming the display from a static high-intensity state to a variable state that balances visibility requirements with safety considerations for surrounding traffic.
2Reliability
If the display unit minimizes influence on nearby vehicles by reducing light intensity, then the traffic safety is improved, but the information becomes unnoticeable and hard to understand
Solution Approach 1:
The display unit employs dynamic light emission control that adapts to the presence of nearby vehicles. When no vehicles are detected in the predetermined area, the display operates in a first light emission state with high intensity to ensure information is clearly visible and understandable to passengers. When vehicles are detected, it transitions to a second state that minimizes influence. This dynamic behavior ensures information visibility is maintained when safe to do so.
Solution Approach 2:
The system modifies the light emission parameters (intensity, color, duration) of the display unit based on real-time detection of nearby vehicles. By changing these parameters dynamically, the system ensures that information remains noticeable and understandable during periods when traffic safety conditions permit, while still prioritizing safety when vehicles are present in the predetermined area.

Function Achieved in This Case
The device ensures sufficient information provision to passengers while reducing the impact on nearby vehicles by dynamically adjusting display modes, maintaining visibility and safety standards.

AI summary
An information providing device includes a display unit configured to display information to a preset view area by emitting light, a detection unit, a first determination, a second determination unit, and a control unit configured to perform an operation control of the display unit. The display unit displays the information in a main display mode and a sub display mode having a less influence on a travelling of a nearby vehicle than the main display mode has. While the information is displayed in the main display mode, the control unit switches the main display mode to the sub display mode or stops an operation of the display unit when the first determination unit determines that the possibility of entry exceeds the threshold, or when the second determination unit determines that the nearby vehicle exists in the view area.
