Adaptive Rearview Mirror Control for Blind Spot-Free Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual adjustment of rearview mirrors during driving is distracting and inefficient, potentially compromising driving safety by creating blind spots and diverting attention from the road.
Innovation Solution
An adaptive rearview mirror adjustment method that uses a combination of camera systems to automatically adjust the mirror's angle based on the driver's eye position, the position of the mirror, and the position of nearby vehicles, calculating auxiliary angles and adjustment angles to ensure optimal viewing without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver manually adjusts the rearview mirror during driving, then the driver can customize the viewing angle to personal preference, but the driver's attention is diverted from the road and driving safety is compromised
Solution Approach 1:
The system enables automatic rearview mirror adjustment by detecting the driver's eye position and calculating the optimal viewing angle, allowing the mirror to adjust itself without requiring manual intervention from the driver during driving operations
Solution Approach 2:
The patent replaces the manual mechanical adjustment system with an automated optical-detection-based system that uses eye position detection and angle calculation algorithms to determine and execute mirror positioning automatically
2Adaptability or versatility
If the driver manually adjusts the rearview mirror, then the viewing angle can be customized, but the adjustment process is time-consuming and creates blind spots
Solution Approach 1:
The system performs preliminary detection of the driver's eye position and calculates the optimal mirror angle in advance, enabling the mirror to be pre-positioned correctly before the driver needs to view it, eliminating the need for time-consuming manual adjustment during driving
Solution Approach 2:
The system continuously detects the driver's eye position and uses this feedback to automatically adjust and maintain the optimal mirror viewing angle, ensuring adaptability without requiring manual intervention or creating blind spots during adjustment
3Reliability
If automatic mirror adjustment is implemented, then driving safety is improved by eliminating manual adjustment distractions, but the system complexity increases due to additional sensors and calculation requirements
Solution Approach 1:
The system integrates multiple functions into a unified automatic adjustment mechanism that combines eye position detection, angle calculation, and mirror positioning control, reducing the need for separate manual adjustment controls and simplifying the overall interaction model

AI summary
An adaptive rearview mirror adjustment method includes obtaining a spatial position of a human eye of a driver of a current vehicle and a spatial position of a target rearview mirror, obtaining a horizontal field of view of the driver in the target rearview mirror based on the spatial position of the human eye of the driver and a spatial position of a target rearview mirror, obtaining a next-vehicle image, obtaining a first auxiliary angle of a target next vehicle based on the next-vehicle image, calculating a second auxiliary angle based on the horizontal field of view, the spatial position of the human eye, and the position of the target rearview mirror, obtaining a horizontal adjustment angle of the target rearview mirror based on the first auxiliary angle and the second auxiliary angle, and adjusting a horizontal angle of the target rearview mirror based on the horizontal adjustment angle.
