Trailer Predictive Guide Display for Clearer Towing Maneuvers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to adequately improve visibility of guide lines when a vehicle is towing a trailer, leading to complexity and reduced visibility, which is undesirable for a sustainable transportation system.
Innovation Solution
A control device that acquires the movement state and relative position of a vehicle towing a trailer, and adjusts the display of predictive guides based on these states and positions, including changing visibility modes and hiding or displaying guide lines accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If guide lines for both vehicle and trailer are displayed simultaneously, then complete trajectory information is provided, but visibility deteriorates due to complexity
Solution Approach 1:
The display control unit dynamically adjusts the visibility of guide lines based on real-time movement state and relative position data. When the vehicle and trailer are in specific positional relationships, the system selectively reduces or hides certain guide lines to maintain visibility while preserving essential trajectory information.
Solution Approach 2:
The system changes display parameters (visibility, opacity, or presence) of guide lines based on calculated movement states and relative positions. By adjusting these display parameters dynamically, the system optimizes the balance between providing complete trajectory information and maintaining visual clarity.
2Loss of information
If multiple guide lines are displayed to show predicted paths, then navigation information is comprehensive, but the display becomes complicated and hard to read
Solution Approach 1:
The system extracts and displays only the essential guide lines needed for safe navigation based on the current movement state and relative position. By selectively removing redundant or less critical guide lines, the system reduces display complexity while preserving vital navigation information.
Solution Approach 2:
The display configuration changes dynamically according to the vehicle's movement state and trailer position. The system adaptively determines which guide lines to display or hide, transforming the static display into a dynamic one that responds to real-time conditions.

AI summary
A control device includes a movement state acquisition unit 55 that acquires a movement state of a vehicle 10 towing a trailer 60, a relative position acquisition unit 56 that acquires a relative position between the vehicle 10 and the trailer 60, and a display control unit 57 that displays a first predictive guide indicating a predicted passing area of the vehicle 10 and a second predictive guide indicating a predicted passing area of the trailer 60. The display control unit 57 changes display of at least one of the first predictive guide of the vehicle 10 and the second predictive guide of the trailer 60 based on the movement state of the vehicle 10 and the relative position between the vehicle 10 and the trailer 60.
