Full Display Mirror Assembly for Dynamic Blind Spot Turn Warnings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional rearview mirrors do not effectively alert drivers to blind spots or provide adequate warnings when a vehicle is about to turn into a blind spot with an object present, leading to potential collision risks.
Innovation Solution
A full display mirror assembly with an electro-optic assembly, display module, and imager modules that generate distinct warning indicia in different regions based on the detection of objects in blind spots and the vehicle's turning intentions, using electrochromic components and processors to dynamically adjust display states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional rearview mirrors are used, then the device complexity is low, but the driver's situational awareness of blind spots is insufficient
Solution Approach 1:
The patent combines multiple functions into a single mirror assembly: the electro-optic medium integrates blind spot detection display, rearview reflection, and warning indicia presentation capabilities. The imager modules, electro-optic medium, and display regions are merged into one cohesive system that performs both traditional rearview and advanced blind spot monitoring functions simultaneously.
Solution Approach 2:
The electro-optic medium serves multiple purposes: it acts as a reflective surface for traditional rearview functionality, a display medium for blind spot detection imagery, and a dynamic warning system that can enlarge regions and change transparency based on detected conditions. This multi-functionality eliminates the need for separate blind spot detection devices.
2Reliability
If static warning indicia are displayed, then the device complexity is low, but the effectiveness of warning during turning maneuvers is insufficient
Solution Approach 1:
The system dynamically adjusts the display characteristics based on real-time conditions. The processor controls the electro-optic medium to enlarge the display region and adjust transparency when turning maneuvers are detected, creating a dynamic warning system that adapts to the driver's actions and enhances warning effectiveness during critical moments.
Solution Approach 2:
The system incorporates feedback loops where the processor continuously monitors imager module data and steering input, then adjusts the display parameters accordingly. When a turn is detected, the system feedbacks by enlarging the warning region and adjusting transparency to match the turning maneuver, creating a responsive warning system.

AI summary
A full display mirror assembly for a vehicle includes an electro-optic assembly containing an electro-optic medium, a display module, and at least one imager module configured to capture a blind spot. A processor and a memory including instructions that, when executed by the processor, cause the processor to, in response to a detection of an object in the blind spot, generate a first warning indicia in a first region of the full display mirror assembly. The processor is further caused to, in response to a detection that a vehicle containing the full display mirror assembly is turning or about to turn towards the blind spot with the object, generate a second warning indicia in a second region of the full display mirror assembly by enlarging the first region.
