Auxiliary Identification Device for Vehicle Road Signs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle auxiliary devices fail to provide real-time information about road conditions and signs, leading to driver negligence and potential accidents due to cluttered visual fields, weather issues, and outdated information.
Innovation Solution
An auxiliary identification device with a camera module, controller, and display that captures and identifies video in the vehicle's direction, sorting and prioritizing road signs for display to ensure the driver receives critical information in a timely manner, with adjustable settings based on user needs or environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the driver's field of view is expanded to see more road signs, then the driver can notice more indicator objects, but the image becomes disorderly and causes driver fatigue
Solution Approach 1:
The patent extracts critical road sign information from the complex visual field and presents it in a simplified, organized manner through the display device. The system identifies and extracts only the most important indicator objects (road signs, traffic signals, etc.) from the cluttered road environment, separating them from irrelevant visual noise to prevent driver fatigue while maintaining information completeness
Solution Approach 2:
The patent segments the driver's field of view into multiple display regions, with different importance levels assigned to different areas. Critical road signs are displayed in prominent positions while less important information is placed in secondary regions, creating an organized hierarchical structure that improves readability and reduces cognitive load
2Productivity
If the vehicle travels at high speed, then productivity is improved, but the driver's field of view becomes limited and reaction time is reduced
Solution Approach 1:
The patent performs preliminary identification and prioritization of road signs before the driver needs to react. The system continuously monitors and pre-processes visual information, identifying critical indicator objects in advance and preparing them for immediate display, thereby reducing the driver's reaction time even at high speeds
Solution Approach 2:
The patent introduces a display device as an intermediary between the road environment and the driver. This intermediary processes visual information, identifies critical road signs, and presents them in a simplified format, allowing the driver to react quickly without directly scanning the complex road environment at high speeds
3Loss of information
If all road signs are displayed equally, then complete information is provided, but the driver cannot quickly identify critical signs
Solution Approach 1:
The patent applies local quality by assigning different display priorities and visual characteristics to different regions of the display and different types of road signs. Critical indicator objects receive prominent positioning, larger display size, and enhanced visual characteristics, while less important information is displayed with reduced emphasis, allowing the driver to quickly identify critical signs while maintaining information completeness

AI summary
An auxiliary identification device for indicator objects and an auxiliary identification and display method therefor are provided. The auxiliary identification device includes a camera module, a controller, and a display. The camera module is configured to obtain a video in a first direction. The controller is coupled to the camera module and is configured to capture and identify multiple indicator objects in the video. Each of the indicator objects includes indication information. The controller sorts the indicator objects to determine a priority display order of the indicator objects, and further generates a display image signal according to the priority display order. The display is coupled to the controller and is configured to sequentially display the indicator objects according to the display image signal.
