Electronic Rear-View Mirror Automatic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle rear-view mirror systems are inconvenient as they require manual switching between display and reflecting modes, which can be less efficient for drivers depending on vehicle circumstances.
Innovation Solution
A vehicle mirror system with an electronic rear-view mirror that automatically switches between display mode and reflecting mode based on determination criteria related to the rear field of view, using a control component to manage the switching between displaying captured images and showing what is behind the vehicle optically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual switching between display mode and reflecting mode is implemented, then the driver can control the mirror mode, but the operation convenience deteriorates when frequent switching is needed
Solution Approach 1:
The mirror system automatically determines and switches between display mode and reflecting mode based on detected circumstances (such as roof opening/closing, parking detection, image quality assessment) without requiring manual driver input. The system serves itself by autonomously selecting the appropriate mode based on environmental conditions and vehicle state.
Solution Approach 2:
The system continuously monitors various parameters (roof position, vehicle motion state, image quality metrics such as blur and distortion levels) and uses this feedback to automatically switch mirror modes. The control component receives feedback from sensors and image processing results to make real-time mode switching decisions.
2Measurement precision
If display mode is used to show rear-view images, then the driver can see clear images, but the device complexity increases compared to simple optical reflection
Solution Approach 1:
The mirror system dynamically adjusts its operational mode based on real-time conditions. The control component enables the mirror to switch between simple optical reflection and complex display modes, utilizing the display component and image capturing device only when necessary, thereby managing complexity adaptively rather than permanently.
Solution Approach 2:
The mirror system integrates multiple functions into a single device: it can operate as a simple optical reflector, an electronic display showing captured images, or an imaging device that processes and analyzes scene quality. This multi-functionality allows the system to provide clear images when needed while maintaining simplicity for routine operation.

Function Achieved in This Case
Enables convenient switching between display and reflecting modes according to various circumstances, enhancing driver convenience by automatically adapting to changes in the vehicle's rear field of view, such as during roof operations or when blurring/distortion occurs.
Implementation Method 1
an image capturing component provided in a rear portion of the vehicle
Implementation Method 2
displays, by means of a display component, vehicle rear-view images captured by an image capturing component
Implementation Method 3
calculates degrees of distortion and blurring of the recognition target objects and textures in captured images

AI summary
A vehicle mirror system that includes: an electronic rear-view mirror that is switchable between a display mode in which the electronic rear-view mirror displays, by means of a display component, vehicle rear-view ages captured by an image capturing component provided at a rear portion of the vehicle, and a reflecting mode in which the electronic rear-view mirror shows, by optical reflection, what is behind the vehicle; and a control component that causes switching of the electronic rear-view mirror to either the display mode or the reflecting mode in a case in which a determination criterion relating to a field of view in a rear direction of the vehicle has been met.
