Camera-Wing View Control for Trailer Rear-End Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trailer tracking systems struggle to accurately track and monitor the rear end of trailers, and vehicle viewing systems provide limited and unclear views of critical areas, especially in adverse weather conditions, leading to difficulty in identifying potential collision zones.
Innovation Solution
A camera-wing-system for vehicles that includes a camera, an electronic control unit, and an image section, which updates the displayed view based on the vehicle's driving situation to maintain the trailer's rear end in view, using a ToF sensor to measure distance and adjust the image section accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the area of concern is enlarged in the display, then the visibility of critical areas is improved, but the resolution of the area of concern deteriorates
Solution Approach 1:
The display is segmented into multiple regions with different characteristics. The area of concern is displayed in a first region with enhanced visibility (enlarged, brighter), while other areas are displayed in a second region with standard resolution. This segmentation allows critical areas to be enlarged without sacrificing overall image quality.
Solution Approach 2:
Different regions of the display are assigned different quality characteristics. The area of concern receives enhanced local quality through enlargement and increased brightness, while maintaining standard resolution elsewhere. This allows optimization of visibility for critical areas without degrading the overall image resolution.
2Adaptability or versatility
If multiple viewing options are provided for different areas, then the versatility of the viewing system is improved, but the device complexity increases
Solution Approach 1:
The camera system captures a single wide-angle field of view that serves multiple purposes: it provides both the area of concern and surrounding areas in one image, eliminating the need for multiple cameras or complex switching mechanisms. The processing system then selectively enhances different regions based on driving situations.
Solution Approach 2:
The system dynamically adjusts which area is designated as the area of concern based on the driving situation. The ECU determines the area of concern in real-time and adjusts the display accordingly, providing versatility without requiring multiple fixed viewing modes or complex mechanical adjustments.
3Area of stationary object
If the field of view is widened to capture more areas, then the coverage is improved, but the resolution of individual areas deteriorates
Solution Approach 1:
The wide field of view image is segmented into different regions, with the area of concern receiving enhanced processing. The system divides the captured image into a first region (area of concern) and a second region (surrounding areas), allowing selective enhancement of resolution and visibility for critical areas while maintaining wide coverage.
Solution Approach 2:
The system changes display parameters selectively for different regions. The area of concern is displayed with enhanced brightness and enlargement, while surrounding areas maintain standard parameters. This allows wide field of view coverage while providing high resolution for critical areas through parameter optimization.
