Trailer Striking Area Prediction in Vehicle Camera Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During forward turning operations of tractor-trailer configurations, it is challenging for vehicle operators to gauge the motion of the trailer side using conventional mirror and camera systems, leading to wider turns than necessary to avoid striking objects inside the turn arc.
Innovation Solution
A camera monitoring system (CMS) with a CMS controller connected to multiple cameras around the vehicle, including side and rear cameras, which uses a trailer striking area prediction module to define a striking area geometry by predicting future positions of prediction points along the trailer edge, and overlays this geometry onto the rear view display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional mirror and camera systems are used to monitor the surrounding environment, then the vehicle operator can see the surrounding environment, but it is difficult to gauge the motion of the trailer side during turning operations
Solution Approach 1:
The system performs preliminary action by predicting the future striking area of the trailer before the actual turn occurs. The prediction module calculates where the trailer will be positioned during the turning maneuver based on current vehicle state and turning parameters, allowing the operator to see the potential hazard area in advance and adjust the turning path accordingly.
Solution Approach 2:
The system introduces an intermediary visual overlay (striking area indicator) that mediates between the raw camera footage and the operator's understanding of trailer motion. This overlay acts as a visual intermediary that translates complex trailer dynamics into an intuitive graphical representation showing the potential striking area.
2Reliability
If operators use wider turns to ensure objects are not struck, then collision risk is reduced, but turning efficiency and productivity decrease
Solution Approach 1:
The system provides real-time feedback by displaying the predicted striking area overlay during turning operations. This feedback loop allows the operator to see the exact area that could be struck, enabling precise adjustments to the turning path that maintain safety while optimizing turning efficiency.
Solution Approach 2:
The system enables parameter changes by providing information that allows the operator to adjust turning parameters (such as turning radius and speed) based on the displayed striking area. This leads to optimized turning parameters that balance safety and efficiency.
3Reliability
If the striking area is predicted and displayed as an overlay, then operators can adjust turning path to avoid collisions, but the system complexity increases
Solution Approach 1:
The system achieves universality by integrating multiple functions into a single integrated module. The striking area prediction module combines trailer tracking, motion prediction, and visual overlay generation within the existing camera monitoring system framework, avoiding the need for separate complex subsystems.
Solution Approach 2:
The system uses copying by creating a virtual representation (visual overlay) of the predicted striking area based on real camera feeds and calculated trajectory data. This graphical copy allows the operator to visualize potential hazards without requiring physical markers or additional hardware in the environment.
