AR Overlay for Vehicle Service Component Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Technicians face difficulties in intuitively accessing and servicing complex vehicle systems due to non-matching wiring schematics and intricate wiring designs, which lack visual representation of actual vehicle components.
Innovation Solution
The implementation of augmented reality and virtual reality technologies using a VR/AR device that superimposes virtual components over real-time video feed, allowing technicians to select components for detailed information and navigate through virtual or augmented reality views to locate and understand vehicle assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional wiring schematics and manual documentation are used, then technicians can access vehicle system information, but the information is not visually intuitive and difficult to match with actual vehicle components
Solution Approach 1:
The patent creates a virtual copy of the vehicle and its components that can be overlaid onto the real vehicle. This virtual model replicates the physical vehicle's structure, wiring, and components, allowing technicians to view detailed information about actual components by looking at their virtual representations through the AR device. The virtual copy maintains spatial relationships and visual characteristics of the real vehicle, making it easy to match schematics with actual components.
Solution Approach 2:
The patent transitions from two-dimensional wiring schematics and manual documentation to a three-dimensional virtual model that can be overlaid onto the physical vehicle. This adds a spatial dimension to the information presentation, allowing technicians to view vehicle systems from multiple angles and perspectives while maintaining direct visual correspondence with the actual vehicle components.
2Loss of information
If detailed information about vehicle components is provided in traditional formats, then technicians have access to comprehensive data, but the information is not easily accessible in context during service operations
Solution Approach 1:
The AR system allows technicians to independently access detailed component information by simply viewing the virtual model overlaid on the actual vehicle. The system automatically provides context-relevant information without requiring technicians to search through manuals or cross-reference documentation. The virtual model itself serves the technician by displaying all necessary information in the field of view.
Solution Approach 2:
The AR device acts as an intermediary between the technician and the vehicle components. It captures the real vehicle through the camera, overlays the virtual model with detailed information, and presents this combined view to the technician. This intermediary system bridges the gap between physical components and their digital representations, making information instantly accessible in context.
3Loss of information
If complex vehicle systems are documented using traditional methods, then all necessary information can be recorded, but technicians struggle to visualize and understand the spatial relationships of components
Solution Approach 1:
The patent creates a precise virtual replica of the vehicle's complex systems, including wiring harnesses, components, and their spatial relationships. This virtual copy maintains all the complexity of the original system but presents it in a visually intuitive format that can be overlaid onto the physical vehicle, allowing technicians to understand complex spatial relationships without navigating complicated 2D schematics.

AI summary
In some embodiments of the present disclosure, augmented reality and/or virtual reality technologies are used to present information for a vehicle to a technician. A virtual object model file that includes a context model and at least one assembly detail model is created based on a vehicle design model. A VR/AR device uses its camera to generate video of a vehicle, and superimposes a depiction of a vehicle component or assembly from the virtual object model file over the video in the location in which the vehicle component or assembly is actually located, as if the vehicle were “see-through.” The VR/AR device may then also allow the technician to select specific components of the depicted assembly in order to retrieve and display detailed information about the component.
