Vehicle Mirror Adjustment via Driver Eye Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vehicle mirror adjustment systems require manual input by drivers, which is cumbersome and often not adjusted for multiple users, leading to suboptimal viewing angles and increased risk during operation.
Innovation Solution
An in-vehicle computing system that uses cameras and sensors to automatically adjust mirror angles based on the driver's eye position relative to the mirrors, determining the ideal viewing angle through image analysis and geometric calculations to ensure optimal field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual mirror adjustment is used, then device complexity is reduced, but ease of operation deteriorates and time consumption increases
Solution Approach 1:
The system automatically detects driver eye position and adjusts mirror angles without manual intervention. The control section computes proper mirror angles based on detected eye positions and automatically instructs the door mirror driving sections to set mirrors at optimal angles, making the system self-adjusting rather than requiring manual operation.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated optical-detection-and-control system. Instead of physical switches or buttons, the system uses eye position detection (optical/visual methods) and electronic control signals to automatically position mirrors, substituting mechanical user interaction with automated sensing and actuation.
2Productivity
If automated mirror adjustment is implemented, then ease of operation improves, but device complexity increases
Solution Approach 1:
The system automatically detects driver eye position and adjusts mirror angles without manual intervention. The control section computes proper mirror angles based on detected eye positions and automatically instructs the door mirror driving sections to set mirrors at optimal angles, making the system self-adjusting rather than requiring manual operation.
Solution Approach 2:
The system performs mirror adjustment automatically upon driver entry or system activation, determining optimal mirror positions before driving begins. This preliminary automated adjustment eliminates the need for manual setup and ensures proper mirror configuration is established in advance.
3Loss of time
If manual adjustment is required, then device complexity is minimized, but loss of time increases
Solution Approach 1:
The system automatically detects driver eye position and adjusts mirror angles without manual intervention. The control section computes proper mirror angles based on detected eye positions and automatically instructs the door mirror driving sections to set mirrors at optimal angles, making the system self-adjusting rather than requiring manual operation.
Solution Approach 2:

AI summary
Technologies for mirror adjustment include an in-vehicle computing system of a vehicle to determine a position of a feature of a face of a driver of the vehicle in an image captured by a camera of the vehicle. The in-vehicle computing system determines a position of the feature of the face of the driver relative to a mirror of the vehicle based on configuration data of the vehicle and the captured image. The in-vehicle computing system further determines an angle between the feature of the face of the driver, the mirror, and an ideal normal of the mirror. The configuration data identifies a location of the camera relative to the mirror, and the ideal normal is an imaginary line normal to the mirror and extending therefrom when the mirror is positioned in a reference position. The in-vehicle computing system adjusts an orientation of the mirror based on the determined angle.
