Deterministic Digital Twin Architecture for Connected Vehicles
DigitalVehicleTwin establishes a mathematically synchronized cloud replica of an individual software-defined vehicle. By fusing high-rate CAN-XL and Ethernet telemetry with physics-based component models, it mirrors powertrain, chassis, and battery degradation in real time.
Digital Vehicle Twin Core Zonal Architecture
Central Controller: Digital Vehicle Twin Core — ISO 23247 Synchronization Hub
Zonal Control Units & TSN Ring
- High-Rate Telemetry Ingestion Ingress
- Multi-Physics Co-Simulation Runtime
- Virtual State Sensor Observer
- Cryptographic Twin Attestation
- Bidirectional Parameter Actuation
Closing the Loop Between Road Telemetry and Virtual Physics Models
Traditional fleet management stores tabular time-series logs without component context. DigitalVehicleTwin continuously computes state-space differential equations inside the virtual shadow, enabling non-invasive virtual sensing of stresses, temperatures, and wear.
Core Engineering Areas
- Physical-to-Virtual Synchronization — Synchronizing discrete vehicular telemetry frames with continuous ordinary differential equation (ODE) physics solvers.
- Virtual Sensing of Mechanical Stress — Combining wheel speed, steering torque, and accelerometer data with finite element reduced-order models (ROM) to monitor chassis fatigue.
- Degradation Digital Thread — Recording every thermal excursion, hard acceleration, and fast-charge cycle into an unalterable component lifecycle ledger.
