Vehicle Rearview Display Cropping for Open and Closed Tailgates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rearview camera systems in vehicles, particularly in pickup trucks and SUVs, often fail to provide optimal images due to the dynamic movement and orientation of cameras mounted on movable gates, leading to suboptimal views when the gate is in different configurations.
Innovation Solution
A system comprising multiple cameras with specific viewing angles, a processor, and a display screen that adjusts the image cropping and overlays to provide an augmented rearview display, identifying and removing gate shadows, and activating hitch lights when necessary, to ensure clear and relevant views regardless of the gate's configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the rear vision camera is mounted on a movable gate, then the camera can be integrated into the vehicle structure, but the image quality becomes suboptimal when the gate is in different configurations
Solution Approach 1:
The system dynamically adjusts image processing parameters based on gate configuration. The processor detects whether the gate is closed or open and automatically applies different image cropping and enhancement algorithms to maintain optimal image quality in both configurations.
Solution Approach 2:
The system changes image processing parameters including crop regions, enhancement levels, and display configurations based on the detected gate configuration. This allows the same camera to provide optimal images for both closed and open gate states without physical repositioning.
2Adaptability or versatility
If the camera location and orientation change with gate movement, then the system adapts to gate configuration, but the rearview display becomes inconsistent
Solution Approach 1:
The system uses feedback from gate position sensors to automatically adjust image processing. The processor receives signals about gate configuration and dynamically modifies image cropping and enhancement to maintain consistent, reliable rearview displays regardless of gate position.
Solution Approach 2:
The system pre-defines optimal image processing parameters for both closed and open gate configurations. When a configuration change is detected, the appropriate pre-configured processing parameters are immediately applied, ensuring consistent display quality without delay.
3Loss of information
If image cropping is applied to show relevant portions, then the display becomes more relevant, but the field of view is reduced
Solution Approach 1:
The system applies different cropping strategies based on gate configuration. When the gate is closed, it crops to show the lower portion relevant for backing up. When the gate is open, it crops to show the upper portion relevant for viewing around the open gate, maximizing relevance for each specific configuration.

AI summary
Vehicles and systems and methods for providing rearview displays for vehicles are provided. An exemplary system is provided for a vehicle having a gate moveable between closed configuration and opened configurations. The system includes a camera mounted to the gate and configured to collect dynamic pixel images of an area behind the vehicle; a display screen configured to display the collected dynamic pixel images; and memory configured to include executable instructions and a processor configured to execute executable instructions that enable the processor to crop the collected dynamic pixel images to display a lower portion of the collected dynamic pixel images on the display screen when the gate is in the closed configuration, and to crop the collected dynamic pixel images to display an upper portion of the collected dynamic pixel images on the display screen when the gate is in the opened configuration.
