Adaptive Vehicle Side Mirror Switching Between Reflection and Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing side mirrors for vehicles lack the ability to adaptively switch between mirror and display modes based on traveling conditions, limiting their functionality in terms of visibility and information output.
Innovation Solution
A side mirror system equipped with a camera, a mirror panel, a display panel, and a processor that determines the operational mode (mirror or display) based on vehicle traveling information, allowing the mirror to function as a conventional mirror or display a side-rear image captured by the camera, and providing visual effects for ambient situation information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a side mirror uses only a conventional mirror panel, then it provides simple and reliable reflection of the side-rear area, but it cannot output additional information such as blind spot detection or ambient situation data
Solution Approach 1:
The side mirror assembly is designed to perform multiple functions: conventional mirror reflection, camera-based side-rear image display, blind spot detection visualization, and ambient situation information output. The control unit enables the mirror assembly to adaptively switch between these functions based on vehicle operating conditions, transforming a single-function mirror into a multi-functional information display system that reduces information loss without proportionally increasing complexity
2Adaptability or versatility
If a side mirror uses only a display panel to show camera images, then it can output side-rear images and information, but it cannot function as a conventional mirror when needed
Solution Approach 1:
The side mirror assembly incorporates dynamic switching capability between mirror mode and display mode based on vehicle traveling conditions. The control unit receives vehicle state information and automatically transitions the mirror assembly between reflecting mode (when mirror function is needed) and camera image display mode (when information output is prioritized). This dynamic adaptability ensures the system maintains reliability for mirror functions when required while achieving versatility in different operating scenarios
Solution Approach 2:
The control unit acts as an intermediary that manages the transition between mirror panel and display panel operations. It processes vehicle traveling information and determines the appropriate operating mode, ensuring reliable switching between conventional mirror reflection and camera-based image display. This intermediary control mechanism maintains system reliability by making intelligent decisions about when to use each function based on real-time vehicle conditions
3Loss of information
If a side mirror provides comprehensive information display, then it enhances driver awareness, but it increases energy consumption
Solution Approach 1:
The side mirror assembly uses periodic or conditional activation of the display function rather than continuous operation. The control unit activates the display panel and information output only when specific vehicle traveling conditions are met (such as when blind spot detection is relevant or when the vehicle is in appropriate operating states). This periodic action approach provides comprehensive information to enhance driver awareness when needed while minimizing energy consumption by keeping the display and processing functions inactive during unnecessary periods
4Object-affected harmful factors
If a side mirror is folded to reduce air drag, then it improves fuel efficiency, but it cannot provide mirror reflection or camera image display
Solution Approach 1:
When the side mirror is folded and cannot provide physical reflection, the system uses a camera to capture images of the side-rear area and displays them on the display panel. This creates a visual copy of the scene that would normally be seen in the mirror, allowing the driver to maintain awareness of the side-rear environment even when the physical mirror is retracted to reduce air drag. The camera-based image copying function compensates for the loss of mirror reflection capability

AI summary
A side mirror for a vehicle includes a camera, a mirror panel disposed at a portion of the side mirror, a display panel stacked on the mirror panel, and at least one processor configured to cause the side mirror to enter one of a mirror mode or a display mode based on vehicle traveling information, based on the side mirror being in the mirror mode, to output, on a portion of the display panel, a visualization on a mirror image that appears in the mirror panel, based on the side mirror being in the display mode, to output, on the display panel in the display mode, a side-rear image captured by the camera, and based on the side mirror being in the display mode, to provide, a visual effect to a portion of the side-rear image regarding ambient situation information.
