Vehicle A Pillar Blind Spot Visualization via Camera and Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The A pillars of vehicles create visual blind areas for drivers, affecting safety due to their width, which if too small compromises structural integrity or too large restricts the field of view.
Innovation Solution
A vehicle auxiliary display device comprising a first camera to capture the driver's position, a second camera to image the area outside the pillar, and a processor to determine and display the shielding area, allowing the driver to visualize the blind spot through a display on the pillar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the width of the A pillar is increased to improve structural strength, then the bearing capacity is improved, but the driver's field of view is reduced due to increased visual blind areas
Solution Approach 1:
The patent introduces an auxiliary display device as an intermediary between the driver and the blind area. The display shows real-time images captured by cameras positioned to view areas obscured by the A pillar, allowing the driver to see around the pillar without reducing its structural width. This mediator compensates for the visual obstruction caused by the strengthened pillar.
Solution Approach 2:
The system creates a visual copy of the blind area by using cameras to capture images of the region obscured by the A pillar and displaying these images on the auxiliary display. This copy allows the driver to perceive the environment in the blind area without requiring a change to the physical pillar structure.
2Object-affected harmful factors
If the width of the A pillar is decreased to improve the driver's field of view, then the visual blind area is reduced, but the structural bearing capacity is compromised
Solution Approach 1:
The auxiliary display device serves as an intermediary that compensates for the visual deficiency created by a thinner A pillar. By providing real-time images of the blind area through the display, the system allows the pillar to be made narrower without sacrificing the driver's effective field of view, thus resolving the contradiction between structural strength and visual accessibility.
3Reliability
If the A pillar width is optimized for structural integrity, then the bearing capacity is maintained, but the driver's awareness of the environment around the pillar is reduced
Solution Approach 1:
The system implements feedback by continuously capturing images of the blind area with cameras and displaying them in real-time on the auxiliary display. This feedback loop provides the driver with ongoing information about the environment that would otherwise be obscured by the A pillar, maintaining environmental awareness while preserving structural integrity.
Solution Approach 2:
The auxiliary display acts as an intermediary information channel that supplements the driver's direct vision. It provides additional environmental information that compensates for the visual blockage caused by the structurally optimized A pillar, ensuring the driver maintains comprehensive environmental awareness.

AI summary
A vehicle auxiliary display device includes: a first camera configured to acquire a first image of a position of a user; a second camera configured to acquire a second image within a first range on an outside of a pillar of a vehicle; and a processor configured to determine a shielding area of the pillar shielding the user's line of sight based on the first image, extract an image of the shielding area from the second image based on the second image, and send the image of the shielding area to the user.
