Vehicle Height Warning Display for Regulatory Sign Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driver assistance devices fail to notify drivers when the vehicle height exceeds the regulatory limit due to loaded goods, despite the vehicle height being within the limit before loading.
Innovation Solution
A display controller that receives vehicle height settings, acquires regulatory sign height limits, and displays or outputs warnings if the vehicle height exceeds these limits, ensuring accurate notification based on the actual vehicle height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the notification system uses a fixed vehicle height threshold, then the device structure is simple, but the notification accuracy deteriorates when loaded goods change the vehicle height
Solution Approach 1:
The notification system dynamically adjusts the vehicle height threshold based on detected changes in vehicle height, rather than using a fixed threshold. This allows the system to adapt to changing vehicle conditions (such as loaded goods) and maintain notification accuracy without requiring complex additional sensors
Solution Approach 2:
The notification device uses its existing display and detection capabilities to monitor vehicle height changes and automatically adjust notification thresholds, making the system self-adapting without requiring external intervention or complex additional hardware
2Reliability
If the notification is always displayed, then the driver is ensured to receive warnings, but redundant notifications occur when vehicle height is within limits
Solution Approach 1:
The system continuously monitors vehicle height and compares it against dynamically adjusted thresholds, providing feedback-based notification control. Notifications are triggered only when the vehicle height exceeds the current threshold, preventing redundant warnings while ensuring reliable alerts when needed
Solution Approach 2:
The notification threshold parameter is dynamically changed based on detected vehicle height variations. When the vehicle height increases due to loaded goods, the threshold is adjusted accordingly, ensuring that notifications are reliable and context-appropriate rather than redundant

AI summary
A display controller includes a receiving part that receives setting of a vehicle height of a vehicle, an acquisition part that acquires a height limit of a vehicle height indicated by a vehicle height restriction regulatory sign installed in a region ahead of the vehicle, and a display control part that cause a display part to display an image corresponding to the regulatory sign, wherein the display control part causes the display part to display the image if the set height of the vehicle received by the receiving part is greater than the height limit of the vehicle height acquired by the acquisition part, and does not cause the display part to display the image if the set height of the vehicle is equal to or less than the height limit of the vehicle height.
