Vehicle Interior Simulation Using Extrinsic Reference Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test apparatuses for vehicle passenger compartments fail to accurately simulate real vehicle conditions and do not provide a sufficiently immersive virtual environment, limiting the evaluation of physical element configurations and their ergonomic, design, and aesthetic performance.
Innovation Solution
A method and apparatus that adjust physical elements to match a pre-processed virtual model using an electronic processing unit, virtual reality viewer, and wearable sensors to align the user's view with the virtual model, allowing for complete immersion and recreation of the vehicle's interior, including non-physical components and features like colors and finishes.

Engineering Contradiction Analysis
1Adaptability or versatility
If motion capture technique with markers is used to superimpose virtual scene on real environment, then immersive virtual environment is achieved, but computational cost increases due to absence of extrinsic reference system
Solution Approach 1:
The patent introduces an extrinsic reference system comprising reference points positioned in the physical environment as an intermediary between the physical test apparatus and the virtual simulation environment. This reference system serves as a mediator that enables accurate alignment and reduces computational complexity by providing a stable coordinate framework, eliminating the need for complex marker-based motion capture techniques.
2Manufacturing precision
If physical elements are adjusted to match virtual model positions, then alignment between physical and virtual environments is improved, but adjustment time and complexity increase
Solution Approach 1:
The patent replaces manual mechanical adjustment of physical elements with an automated optical measurement and control system. Optical devices capture the positions of reference points, the electronic processing unit calculates the transformation parameters, and the system automatically adjusts the physical elements to match the virtual model, significantly reducing adjustment time while maintaining high precision.
Solution Approach 2:
The system enables self-adjustment of the physical test apparatus by using the captured optical data and automatically computing the required transformations. The electronic processing unit processes the reference point positions and determines the adjustment parameters without requiring manual intervention, allowing the system to self-calibrate and align with the virtual model efficiently.

AI summary
A method for checking and/or configuring the arrangement of physical elements of a vehicle includes providing a test apparatus configured to simulate the arrangement of the physical elements of the vehicle and having a support structure to which one or more physical elements are joined, adjustable relative to the support structure, acquiring or processing a virtual model representative of an arrangement of the one or more physical elements relative to the support structure and physically positioning the one or more physical elements according to the virtual model arrangement, defining a first reference point, a position of the first reference point relative to the support structure being known, and measuring a relative distance between the first reference point and a second reference point on a virtual reality viewer, interfacing a user with an electronic processing unit, and acquiring and transmitting data indicative of the user's movements to the electronic processing unit.
