Rear-View Mirror Control for Driver Position Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear-view mirror systems in vehicles have limited visibility when drivers change their position during driving, especially on curved roads or slopes, and manual adjustments are unsafe and inefficient.
Innovation Solution
A control system that uses a camera to monitor the driver's body movements and adjust the rear-view mirror's field of view dynamically, allowing for proportional changes based on the driver's behavior and posture to maintain optimal visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mirror field of view is fixed in the vehicle's reference frame, then the mirror adjustment is simple and stable, but the visibility becomes suboptimal when the driver changes their driving position
Solution Approach 1:
The patent applies the dynamics principle by transitioning the mirror system from a static, fixed field of view to a dynamic system that automatically adjusts the mirror field of view based on real-time detection of driver position changes. The control system continuously monitors driver position via camera and adjusts mirror angles accordingly, enabling the system to adapt to varying driving conditions while maintaining optimal visibility throughout the driving sequence.
2Ease of operation
If the driver manually adjusts the mirror during driving, then the visibility can be optimized for the current position, but the driver's attention is diverted from the road
Solution Approach 1:
The patent implements the self-service principle by enabling the mirror system to automatically adjust itself based on detected driver position changes, eliminating the need for manual intervention. The control system autonomously processes camera data to determine driver position and相应地 adjusts mirror angles, providing the adjustment function while allowing the driver to maintain full attention on the road.
Solution Approach 2:
The system employs feedback by continuously monitoring driver position through the camera and using this information to automatically adjust mirror settings. The control system creates a closed-loop system where driver position data feeds back to the mirror control, enabling real-time optimization of visibility without requiring driver action.
3Device complexity
If a standard mirror adjustment is used for normal driving scenarios, then the setup is simple and quick, but the visibility is inadequate for curved roads or changing driving conditions
Solution Approach 1:
The patent transforms the static mirror adjustment system into a dynamic one that automatically adapts to different driving scenarios including curved roads, slopes, and varying driver positions. The system uses real-time driver position detection to determine appropriate mirror angles for each scenario, providing comprehensive scenario coverage while maintaining system simplicity through automated control.
Data Source
AI summary
A vehicle system includes at least one rear view device, a sensor, and at least one processor. The sensor is for capturing data relating to a vantage point of an occupant within a vehicle. The processor is configured to (i) determine, from the captured data, a vantage point characteristic and (ii) based on a classification of the determined characteristic, generate a signal for adjusting a field of view of the at least one rear view device.
