Electronic Rearview Distance Display With Moving Color Cursor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers struggle to accurately determine the distance between their vehicle and vehicles behind them, especially in low visibility conditions such as at night or in tunnels, leading to safety hazards due to the limitations of traditional rearview mirrors.
Innovation Solution
A vehicle distance reminder system that uses a display device with a cursor that moves and changes color based on the relative distance to the vehicle behind, providing visual feedback through an electronic rearview mirror.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional rearview mirrors are used, then the device structure is simple, but the driver cannot accurately determine the distance to vehicles behind in low visibility conditions
Solution Approach 1:
The patent replaces the traditional optical mechanical rearview mirror system with an electronic display system that uses sensors (such as radar or cameras) to detect distance and electronically renders visual information on a display screen, enabling accurate distance measurement while maintaining a user-friendly interface
Solution Approach 2:
The patent introduces a cursor as an intermediary visual element on the display screen that represents the distance to the vehicle behind. The cursor's position, size, or color encodes distance information, serving as a mediator between the sensor data and the driver's perception, allowing accurate distance assessment without directly viewing the complex sensor system
2Loss of information
If no visual feedback is provided, then the display device is simple, but the driver cannot assess the distance to vehicles behind
Solution Approach 1:
The patent employs color changes in the cursor or display elements to encode distance information. For example, the cursor may change color based on the detected distance to the vehicle behind, providing intuitive visual feedback about distance assessment while maintaining a relatively simple display structure
Solution Approach 2:
The patent transforms one-dimensional distance data into a two-dimensional visual representation on the display screen through the cursor's position, size, or color attributes. This dimensional transformation makes abstract distance information visually perceivable and easier to interpret by the driver
3Ease of operation
If the cursor position is used to indicate distance, then the visual feedback is intuitive, but the display area required increases
Solution Approach 1:
The patent places the cursor in a specific localized region of the display screen (such as the corner or edge) rather than using the entire display area. This localized approach provides intuitive distance feedback through the cursor's position within a confined space, maintaining ease of operation while minimizing the display area required

AI summary
A vehicle distance reminder system, a vehicle distance reminder method, a storage medium, and a vehicle are provided. The vehicle distance reminder system includes: a distance detection unit configured to detect a relative distance between a target vehicle and the ego vehicle, where the target vehicle is located directly behind or laterally behind the ego vehicle; a display screen configured to display an image of the target vehicle and an image of the ego vehicle, where the display screen is provided with a cursor, the cursor is used to reflect the relative distance, and the cursor is able to move within a target area of the display screen, and a color value of the cursor changes in response to a motion of the cursor.
