3D Vehicle Simulator for ECU Embedded System Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle simulator systems are limited in testing the stability and suitability of ECU embedded systems, as they primarily focus on engine signals and require actual vehicle tests, which are costly, time-consuming, and pose safety risks, while also failing to provide a comprehensive view of the vehicle's moving status.
Innovation Solution
A 3D vehicle simulator system that connects an ECU embedded system to a virtual vehicle, using external sensors, a status processing algorithm, and a 3D model rendering engine to display the vehicle's status in real-time, allowing for continuous observation of data and simulation of complex vehicle dynamics without physical testing.

Engineering Contradiction Analysis
1Reliability
If actual vehicle test is performed to test ECU embedded system, then testing reliability is improved, but development time and cost increase significantly
Solution Approach 1:
The patent creates a virtual copy of the vehicle system (virtual vehicle model) that replicates the physical vehicle's dynamics, sensors, and ECU behavior. This virtual model allows repeated testing without the time and cost constraints of actual vehicle tests, while maintaining testing reliability through accurate modeling of vehicle physics and control systems.
Solution Approach 2:
The patent replaces the physical mechanical vehicle system with a computational simulation system. Instead of using actual vehicles for testing, the system uses software-based virtual models that calculate and display vehicle status through 3D graphics and data visualization, eliminating the need for physical testing while maintaining test validity.

4Ease of operation
If engine signal simulation is performed using existing simulator, then engine control testing is improved, but comprehensive vehicle status observation is not achieved
Solution Approach 1:
The patent extends the simulation system to handle multiple types of vehicle data and control systems simultaneously. The virtual vehicle model integrates engine control, transmission, braking, steering, and other vehicle systems, allowing comprehensive observation of all vehicle status parameters through unified 3D visualization and data display interfaces.
Solution Approach 2:
The patent transitions from traditional 2D graph-based data display to 3D visual representation of vehicle status. The system renders three-dimensional models of the vehicle and its components, with real-time status information overlaid in spatial context, enabling intuitive observation of complex vehicle states that cannot be captured by conventional 2D graphs.
