Rear View Mirror Auto-Adjustment for Travel Status Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual adjustment of rear view mirrors in vehicles during different traveling states is complex, leading to poor driving experience and compromised safety, especially when the traveling status is frequently switched.
Innovation Solution
A control apparatus intelligently adjusts the rear view mirror based on the user's control intention and human eye location data, automatically adjusting the mirror to a target location that matches the preferred angle of view, reducing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of rear view mirror is used, then the mirror can be positioned to match user preference, but the operation complexity increases and safety is compromised during frequent traveling status switches
Solution Approach 1:
The control apparatus pre-determines the optimal rear view mirror position based on the vehicle's traveling status (forward or backward) before the user needs to observe. When the traveling status changes, the mirror is automatically adjusted to the pre-calculated position, eliminating the need for manual adjustment during critical moments and ensuring safety is maintained.
Solution Approach 2:
The rear view mirror adjustment system serves itself by automatically detecting the traveling status and adjusting its own position without user intervention. The control apparatus monitors the vehicle status and autonomously controls the mirror actuator to maintain optimal viewing angles, freeing the user from manual adjustment tasks.
2Speed
If automatic adjustment based on traveling status is implemented, then the adjustment speed and responsiveness improve, but the device complexity increases due to additional sensors and control systems
Solution Approach 1:
The control apparatus leverages existing multi-functional components in the vehicle system. The same sensors that detect vehicle status for other control functions (gear position, brake status, steering angle) are also used to determine traveling status for mirror adjustment. This approach achieves fast automatic adjustment without adding dedicated sensors or complex subsystems specifically for mirror control.
Solution Approach 2:
The mirror adjustment control function is merged with the existing vehicle status monitoring system. The control apparatus integrates traveling status detection (combining gear position, brake, and steering signals) with mirror position control in a single unified control logic, eliminating the need for separate detection and control systems.
3Adaptability or versatility
If the rear view mirror is frequently adjusted during frequent traveling status switches, then the preferred angle of view is maintained, but the loss of time and user experience deteriorate
Solution Approach 1:
The system pre-calculates and prepares the optimal mirror position for each traveling status (forward traveling, backward traveling) in advance. When a status change is detected, the mirror is immediately adjusted to the pre-determined position without requiring the user to manually search for the correct angle, thus eliminating adjustment time loss while maintaining adaptability.

AI summary
A rear view mirror control method is provided and may be performed by a control apparatus. The control apparatus may be implemented as a component in a vehicle, for example, a chip, a chip system, or another functional module that can invoke a program and execute the program. The method includes: The control apparatus determines an intention of a user for controlling the vehicle to enter a traveling status or an intention of the user for controlling the vehicle to switch the traveling status, where the traveling status may include, for example, a forward traveling state or a backward traveling state, to automatically adjust a rear view mirror and avoid manual adjustment on the rear view mirror, so as to improve driving experience and traveling safety of the user especially when the traveling status is frequently entered or the traveling status is frequently switched.
