Digital Side-View Mirror Displays for Familiar Driver Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital vehicular vision systems replace side-view mirrors but require drivers to adapt to a new viewing configuration, affecting driving safety due to the display's location at the vehicle's center, which differs from traditional side-view mirror usage.
Innovation Solution
A vehicular vision system with digital side-view mirror assemblies and thin-film displays or projectors positioned at the vehicle's exterior sides or interior surfaces, allowing drivers to view surroundings similar to conventional mirrors, enhanced by image processing and obstacle detection for improved safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the display is located at the center of the front portion of the passenger compartment, then the system provides a consolidated view of surroundings, but drivers need time to adapt to the new configuration affecting driving safety
Solution Approach 1:
The patent divides the display system into multiple segments: thin-film displays are placed on both front door windows and the windshield, rather than using a single centralized display. This segmentation allows different portions of the surround view to be displayed at locations familiar to drivers, reducing adaptation time while maintaining comprehensive surveillance capability
Solution Approach 2:
The patent introduces thin-film display technology as an intermediary between the cameras and the driver's view. These thin-film displays can be transparent or translucent, allowing drivers to see through them while simultaneously viewing the captured images, thus bridging the gap between traditional mirror viewing and digital display systems
2Ease of operation
If conventional side-view mirrors are used, then drivers can easily view surroundings, but visibility is poor in bad weather or dark conditions
Solution Approach 1:
The patent replaces the passive optical reflection mechanism of conventional mirrors with an active electronic imaging system. Cameras capture images that are then displayed on thin-film displays or projectors, substituting the mechanical mirror reflection with an electronic image generation and display system that can be enhanced for various weather conditions
Solution Approach 2:
The patent changes the parameters of the viewing system by using cameras with adjustable sensitivity and displays with variable brightness and transparency. The thin-film displays can adjust their transparency and brightness levels to maintain visibility in different lighting and weather conditions, unlike fixed mirrors

AI summary
A vehicular vision system adapted to be mounted on a vehicle is provided. The vehicular vision system includes two digital side-view mirror assemblies adapted to be disposed respectively at left and right exterior sides of the vehicle, two thin-film displays adapted to be disposed respectively on front door windows of the vehicle, or respectively at a left side portion and a right side portion of a windshield of the vehicle, and a control device. Each of the digital side-view mirror assemblies includes a rear camera configured to capture a rear-side image. The control device is configured to control, one of the thin-film displays to display at least a portion of the rear-side image of one of the exterior sides of the vehicle, and another one of the thin-film displays to display at least a portion of the rear-side image of another one of the exterior sides of the vehicle.
