Electronic Rearview Mirror View Adjustment for Driver Head Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle rearview systems, which rely on cameras and displays, fail to adjust images in real-time to match the driver's changing posture, making it inconvenient for the driver to observe different directions and scene ranges during driving.
Innovation Solution
An electronic rearview mirror system with cameras, displays, sensors, and processors that adjust image position and zoom based on the driver's head and eye movements to provide real-time, optimized viewing angles and details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cameras and displays are installed to capture and show rearward images, then the driver can observe the scene behind the vehicle, but the driver cannot adjust the displayed images to match different driving situations and postures
Solution Approach 1:
The system dynamically adjusts the displayed image position and zoom level based on real-time detection of driver head position and eye direction. The processor modifies the rearward image parameters dynamically as the driver moves their head or changes viewing angle, making the system adaptive to different driving situations and postures without requiring manual intervention.
Solution Approach 2:
The system uses sensors to detect driver head position and eye direction, then feeds this information back to the processor which adjusts the displayed image accordingly. This closed-loop feedback mechanism ensures the displayed rearward image always matches the driver's current posture and viewing preferences, resolving the contradiction between system adaptability and ease of operation.
2Ease of operation
If the displayed image is adjusted to match driver head position and eye direction, then viewing convenience is improved, but system complexity increases
Solution Approach 1:
The electronic rearview mirror system integrates multiple functions into a single device: it captures rearward images, detects driver head position, tracks eye direction, processes this data, and adjusts the displayed image accordingly. By making the electronic rearview mirror a multi-functional universal device, the system achieves convenient adaptive viewing without proportionally increasing overall system complexity.
Solution Approach 2:
The system merges the camera, display, head position sensors, eye direction sensors, and processing unit into an integrated electronic rearview mirror assembly. This consolidation of multiple components into a single unified system provides the adaptive viewing functionality while minimizing the increase in device complexity through component integration.
