3D Vehicle Path Guidelines for Trailer Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Two-dimensional guidelines for vehicle navigation are inadequate in ensuring the vehicle fits within a space along a potential path, particularly when aligning with objects like trailers or navigating through tight spaces.
Innovation Solution
A vehicle guidance system that overlays three-dimensional guideline walls on a camera image, based on the vehicle's steering angle, height, and width, to assist drivers in aligning the vehicle within a space, with adjustable height, width, and position of the guideline walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two-dimensional guidelines are used for vehicle navigation, then the system complexity is low and ease of operation is maintained, but the accuracy of representing the vehicle's path and ensuring proper alignment with objects is insufficient
Solution Approach 1:
The patent transitions from two-dimensional guidelines to three-dimensional guideline walls that extend vertically to represent the vehicle's profile. This dimensional enhancement allows the guidelines to accurately depict the vehicle's height and width, enabling precise alignment assessment with objects like trailers while maintaining visual clarity through overlay on camera images.
2Reliability
If two-dimensional guidelines are used, then the device complexity is low, but the ability to ensure the vehicle fits within a space along the potential path is inadequate
Solution Approach 1:
By adding the vertical dimension to create three-dimensional guideline walls, the system can now represent both the horizontal path and the vertical profile of the vehicle. This enables reliable determination of whether the vehicle will fit within available space, particularly for tall vehicles like pickup trucks navigating through gates or alongside trailers.
Solution Approach 2:
The guideline walls create a visual copy of the vehicle's profile extended along the potential path. This virtual representation allows the driver to see exactly where the vehicle will be positioned in three-dimensional space without physically being there, enabling accurate alignment judgment before executing the maneuver.
3Measurement precision
If three-dimensional guideline walls are implemented, then the alignment accuracy and path representation improve, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical or physical guidance structures with a computational visual overlay system. The three-dimensional guideline walls are generated through software processing of camera images and vehicle parameters, eliminating the need for physical guidance infrastructure while achieving high alignment precision through digital rendering and display.

AI summary
System, methods, and other embodiments described herein relate to aiding a user navigating a vehicle by displaying on a display device, a view of a front or rear of the vehicle with three-dimensional guideline walls overlaying the view. In one embodiment, a method includes, acquiring data that specifies a steering angle for the vehicle. The method includes determining, based on the steering angle data, a left three-dimensional guideline wall and a right three-dimensional guideline wall that together identify a potential path of travel for the vehicle. Each three-dimensional guideline wall has a height based at least on a height of a portion of the vehicle, and wherein the left and right three-dimensional guideline walls have a distance therebetween based at least on a width of the vehicle.
