Vehicle Road Surface Display Control for Conditional Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses for vehicles cannot selectively turn off the notification display on a road surface when it is unnecessary, potentially leading to inconvenience and failure to notify other traffic users when needed.
Innovation Solution
A display apparatus for a vehicle equipped with a road surface drawing unit and a control unit that allows turning off the light of the notification display under specific conditions, such as when the vehicle is in the P range or when there are no approaching objects while reversing, thereby reducing unnecessary drawing of the notification display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the notification display is always drawn on the road surface, then other traffic users can be notified of the vehicle's presence, but inconvenience occurs when the notification is unnecessary
Solution Approach 1:
The notification display dynamically adjusts its visibility based on real-time driving conditions. The control unit automatically controls the notification display unit to draw or stop drawing notifications by light according to the shift lever position and vehicle motion state, making the system adaptive rather than static.
Solution Approach 2:
The system continuously monitors the shift lever position and vehicle motion state as feedback signals. Based on this feedback, the control unit determines whether to activate or deactivate the notification display, creating a closed-loop control system that responds to changing conditions.
2Ease of operation
If the driver manually turns off the notification display, then inconvenience is reduced when notification is unnecessary, but the notification cannot be drawn when it is needed
Solution Approach 1:
The system performs self-service by automatically determining when notification is needed based on shift lever position and vehicle motion state. The control unit autonomously controls the notification display unit without requiring manual driver intervention, allowing the system to serve itself in deciding when to activate or deactivate the notification.
Solution Approach 2:
The notification display dynamically adjusts its visibility based on real-time driving conditions. The control unit automatically controls the notification display unit to draw or stop drawing notifications by light according to the shift lever position and vehicle motion state, making the system adaptive rather than static.
3Reliability
If the notification display is drawn in all situations, then notification reliability is maintained, but energy is wasted when notification is unnecessary
Solution Approach 1:
Instead of continuously operating the notification display in all situations, the system applies partial action by activating it only when specific conditions are met (P range with reverse motion, or non-P range without reverse motion). This reduces energy consumption while maintaining notification reliability when needed.
Solution Approach 2:
The notification display dynamically adjusts its visibility based on real-time driving conditions. The control unit automatically controls the notification display unit to draw or stop drawing notifications by light according to the shift lever position and vehicle motion state, making the system adaptive rather than static.

AI summary
A vehicle has a function of drawing a notification display on a road surface with light. In a case where a shift position of the vehicle is a P range and a switch for turning off the drawing is selected, it is permitted to turn off the light of the drawing of the notification display. As another condition, in a case where there is no approaching object around the vehicle when the vehicle moves rearward and the switch for turning off the drawing is selected, it is permitted to turn off the light of the drawing of the notification display.
