Rearview Display Overlays for Open Tailgate Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rearview camera systems in vehicles, particularly in pickup trucks and SUVs, do not always provide optimal images due to changes in camera location and orientation when the rear gate moves between closed and opened configurations, necessitating an augmented display that accounts for the vehicle's configuration and potential configurations.
Innovation Solution
A method and system that collect dynamic pixel images using a camera mounted on a moveable gate, such as a tailgate or liftgate, and display graphical overlays on a display screen to depict the gate's outline and projected path, using a processor and sensors to adjust the camera perspective and generate overlays based on user requests or automatic detection of gate status and vehicle dynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rear vision camera is mounted on a moveable gate (tailgate or liftgate), then the camera can provide rearview images in different gate configurations, but the camera location and orientation change dynamically, causing suboptimal images in certain situations
Solution Approach 1:
The system dynamically adjusts the graphical overlay display based on real-time gate position and vehicle motion state. When the gate is opened during reverse operation, the display transitions from showing the closed gate outline to showing the opened gate outline with projected path, adapting to the changing configuration while maintaining reliable visual information for the driver
2Ease of operation
If the rearview display shows only the static closed gate outline, then the display is simple and clear, but it does not provide accurate spatial information when the gate is actually opened
Solution Approach 1:
The system changes the display parameters (gate outline state and projected path visualization) based on the detected gate position and vehicle motion parameters. When the gate is opened and the vehicle is in reverse, the display parameter changes from closed gate outline to opened gate outline with dynamic projected path, providing accurate spatial information while maintaining display clarity through conditional parameter adjustment
3Loss of information
If the system automatically displays graphical overlays based on gate status and vehicle dynamics, then accurate spatial information is provided, but the system complexity increases
Solution Approach 1:
The graphical overlay system serves multiple functions: it displays the gate outline in different configurations, shows the projected path of the moving gate, and adapts to different gate positions and vehicle motion states. This multi-functionality is achieved through a single integrated display system that processes gate position signals and vehicle dynamics to provide comprehensive spatial information, reducing the need for separate systems for each function

AI summary
Vehicles and methods for augmenting rearview displays for vehicles are provided. An exemplary method is provided for augmenting a rearview display for a vehicle having a gate moveable between a closed configuration and an opened configuration. The method includes collecting dynamic pixel images of an area behind the vehicle using a camera connected to the vehicle. Further, the method includes, in response to a command, displaying graphical overlays to the collected dynamic pixel images on a display screen, via a processor, wherein the graphical overlays depict an outline of the gate and/or projected path of the gate in the opened configuration.
