Touchscreen Electronic Rearview Mirror Camera Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic rearview mirrors with display devices lack intuitive and easy-to-understand options for adjusting the viewing angle, particularly for drivers, as they offer numerous complex settings beyond just panning and zooming, including display parameters and interactions with driver assistance systems.
Innovation Solution
A touch-sensitive, multi-touch capable display system is integrated into the electronic rearview mirror, allowing drivers to intuitively control camera orientation, image section selection, and other vehicle systems through familiar gestures and settings, such as panning, zooming, and adjusting display parameters like brightness and contrast, with the ability to configure additional information and vehicle system parameters directly on the touchscreen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device with multiple setting options is provided in the electronic rearview mirror, then the functionality and adaptability are improved, but the ease of operation deteriorates due to the complexity of adjustments
Solution Approach 1:
The patent replaces mechanical adjustment mechanisms with a touch-sensitive display interface. The driver can adjust display parameters, camera angles, and image sections by touching the display surface, eliminating the need for physical knobs, switches, or buttons. This substitution maintains full adjustability while dramatically improving ease of operation through intuitive touch gestures.
Solution Approach 2:
The display device allows the driver to independently adjust all settings directly through the display interface without requiring external controls or complex mechanical systems. The touch-sensitive display serves both as the output medium and the control interface, enabling the system to serve itself for both display and adjustment functions.
2Ease of operation
If a touch-sensitive display is used for controlling multiple parameters, then the ease of operation is improved through intuitive gestures, but the device complexity increases
Solution Approach 1:
The touch-sensitive display serves multiple functions simultaneously: it displays camera images, allows adjustment of display parameters (brightness, contrast, color), controls camera pivoting angles, selects image sections, and interfaces with driver assistance systems. This multi-functionality consolidates what would otherwise require separate controls into a single universal interface, improving ease of operation while managing complexity through integration.
Solution Approach 2:
The patent merges the display function and control function into a single touch-sensitive display unit. The display surface itself becomes the control interface, combining visual output and input reception into one component. This merging eliminates the need for separate mechanical controls, buttons, or switches, thereby improving ease of operation while consolidating system complexity into a single integrated device.
