Solution Overview

Problem

Manual adjustment of rearview mirrors during driving is distracting and inefficient, potentially impacting driving safety by creating blind spots and reducing attention on the road.

Innovation Solution

An adaptive rearview mirror adjustment method that uses computer vision and sensor data to automatically adjust the mirror angles based on the driver's eye position, the vehicle's surroundings, and the position of next vehicles, ensuring optimal viewing angles without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the driver manually adjusts the rearview mirror during driving, then the viewing angle can be optimized for the driver's position, but the driver's attention is distracted from the road, reducing driving safety

Engineering Contradiction:
Improvemanual mirror adjustment capabilityVSAvoiddriving safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The rearview mirror system automatically adjusts itself based on detected driver eye position and next vehicle position, eliminating the need for manual driver intervention. The system uses sensors to detect driver position and cameras to identify next vehicles, then autonomously calculates and applies the optimal mirror angle, allowing the driver to maintain full attention on the road

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical adjustment system with an automated electronic control system. Instead of the driver physically moving the mirror, the system uses electronic actuators controlled by a processing unit that calculates the optimal angle based on sensor data, substituting mechanical manual operation with automated electronic control

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The present invention discloses an adaptive rearview mirror adjustment method in the field of artificial intelligence. The 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, and obtaining a horizontal field of view of the driver in the target rearview mirror based on the spatial position of the human eye and the spatial position of the target rearview mirror; obtaining a next-vehicle image, and 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. The present invention further discloses an adaptive rearview mirror adjustment apparatus. According to embodiments of the present invention, impact on driving safety when a driver is distracted by manual adjustment of a rearview mirror is avoided.
