Simulated Rearview Mirror Display With Dynamic Camera Perspective
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle mirrors have limitations in providing a clear rearward view, especially with obstructions like rear decks, and lack advanced safety features beyond basic reflection.
Innovation Solution
A 'smart mirror' system that uses wireless connectivity and imaging devices to simulate a mirror, offering real-time video feeds and integrating advanced safety features like hazard detection, communication technologies, and AI for enhanced driver assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mirrors are used for rear visibility, then the basic reflection function is provided, but the visibility is obstructed by rear decks and trunk structures
Solution Approach 1:
The patent uses camera devices to capture images of the rear environment and displays them on a display device, creating a digital copy of the mirror function. This electronic mirror system replaces the optical reflection of traditional mirrors, allowing the driver to see behind the vehicle without being blocked by the rear deck or trunk structures.
2Adaptability or versatility
If traditional mirrors are used, then the basic viewing function is provided, but advanced safety features and communication capabilities are lacking
Solution Approach 1:
The patent integrates multiple functions into a single system: the display device not only shows rear camera images for visibility but also detects hazards, provides warnings to the driver, and enables communication with external devices. This multi-functional approach consolidates what would otherwise require separate systems, making advanced features accessible without proportionally increasing overall system complexity.
3Reliability
If video cameras are mounted on the rear bumper to improve rear visibility, then better rear vision is achieved, but the system only works during limited operations like reversing
Solution Approach 1:
The patent makes the mirror simulation dynamic by detecting the driver's head position and eye direction using sensors. The system adjusts which camera feeds are displayed and how the images are processed based on the driver's actual viewing angle and position, allowing the electronic mirror to provide continuous rear visibility assistance throughout various driving operations, not just during reversing.

AI summary
A vehicle system includes a display device that simulates a rear-facing mirror (e.g., rearview mirror). The display device displays a first video captured by a first camera to simulate the rear-facing mirror. The system detects a change in an orientation of the display device from a first orientation to a second orientation and, in response, causes the display device to display a second video captured by a second camera to maintain the simulation of the rearview mirror but from the second orientation. Alternatively, the system causes a corresponding change in the perspective of the first video being displayed on the display device thereby maintaining the effect of the rearview mirror.
