Digital Twin Technology and High-Fidelity Vehicle Model 2026/09/29

Introductions

For vehicle manufacturers, accurately predicting performance and handling during the early stages of vehicle development is a challenging task. Previously, validating with actual vehicles required significant testing resources and was time-consuming, leading to excessively long product development cycles.

Technical Advantages and Features

• High-Fidelity Vehicle Model: Using multibody dynamics to construct models, the accuracy of control simulations exceeds 90%. Reducing models from 3D to 1D retains 80% accuracy and achieves real-time simulation calculations.
• Electric Vehicles Database: Suitable for electric vehicles. Customized vehicle/power system modeling. 7~12 meter buses. 3.5~26 tons trucks. The battery's SOC (State of Charge) estimation accuracy is up to 97%.
• Full Vehicle System Simulation: Based on model development and employing Functional Mock-up Units (FMU), this approach ensures model sharing and interoperability.

Industrial Applications and Business Opportunities

• Industry Applications
  • Electric/Fuel cell commercial vehicles (buses/trucks).
  • Autonomous and Electric Vehicle.
• Application Examples
  • This technology has been transferred to the electric bus manufacturer Tron-e, which has obtained Lane Keeping Assist CSF/ACSF certification, enhancing safety.
  • For electric buses operating on specific routes, whole-vehicle simulations were conducted; the battery status simulations correlate with actual test results.
