Trailer Surround View Adaptation for Obstruction-Free Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mirror replacement systems for vehicles with trailers, such as those using cameras and screens, struggle to provide a sufficient field of vision, especially at different trailer alignments, leading to obscured views and difficulties in monitoring surroundings during maneuvers.
Innovation Solution
The method and device adapt the image representation of vehicle surroundings by adjusting the image section, image ratio, and resolution based on the trailer's alignment, ensuring the trailer does not obscure the view and providing a comprehensive field of vision using image capturing and reproducing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the image capturing device is arranged to monitor lateral and rear surroundings, then the field of vision is improved, but the trailer obscures the view at certain curve radii
Solution Approach 1:
The image reproducing device dynamically adapts the represented section of the surrounding area based on detected trailer alignment. The system continuously monitors trailer position and adjusts the displayed image section to maintain visibility of relevant surrounding areas despite trailer obstruction, transforming a static mirror replacement into an adaptive monitoring system.
Solution Approach 2:
The system changes the parameters of the reproduced image based on trailer alignment conditions. When the trailer obscures the view at certain curve radii, the system modifies which section of the surrounding area is represented, ensuring continuous visibility of critical zones by adapting the display parameters to current driving conditions.
2Area of stationary object
If a large screen is used to provide sufficient field of vision, then the visibility is improved, but the device complexity and cost increase
Solution Approach 1:
Instead of using a permanently large screen to cover all possible viewing angles, the system dynamically adjusts the represented section based on trailer alignment. This allows a smaller screen to effectively provide sufficient field of vision by adapting its content to current driving conditions, reducing device complexity and cost.
3Device complexity
If the image section is fixed, then the device complexity is reduced, but the ability to monitor surroundings during trailer maneuvers is impaired
Solution Approach 1:
The system implements dynamic adaptation of the image section based on detected trailer alignment conditions. The image reproducing device adjusts which section of the surrounding area is represented according to the trailer's position, providing situation-specific monitoring capability that enhances adaptability without requiring overly complex processing.
Solution Approach 2:
The system changes the parameters of the reproduced image section based on trailer alignment. By detecting trailer position and adapting the displayed section accordingly, the system achieves versatile monitoring capability across different driving scenarios while maintaining manageable device complexity through targeted parameter adjustments.
Data Source
AI summary
A method and a device are for detecting and reproducing a lateral and/or rear surrounding area of a vehicle with a trailer, so that the driver can monitor the surrounding area. The surrounding area is detected by at least one image capturing device which produces image data of the surrounding area. The image data is reproduced by at least one image reproducing device arranged in a field of vision of the vehicle driver. A characteristic of the reproduced image section is adapted dependent on an alignment of the trailer relative to the vehicle.
