Why Cabin Twins Matter
- As vehicles morph into rolling experience hubs, Tier-1 suppliers and OEMs need a unified model that links mechanical, electronic, and software states to occupant well-being. Cabin
Twin VP–co-developed by VSI and leading interior supplier partners–creates a physics-based, sensor-fed replica of air-flow, acoustics, haptics, and cognitive load. Multi-Physics Core
- CFD meshes simulate micro-climate, while ray-tracing renders lighting and reflection on digital dash surfaces. Biometric APIs ingest heart rate and galvanic skin response from seat sensors, updating comfort algorithms at 50 Hz. A material model accounts for VOC off-gassing and UV aging, predicting cabin freshness over life-cycle. Software-Defined Control
- A ROS-compatible middleware orchestrates HVAC vanes, ambient LEDs, seat massage, and AR HUD elements as composable services. OTA frameworks push new ambience "themes" in under five minutes with cryptographic roll-back. Validation & Compliance
- Virtual-HIL loops connect the twin to real ECUs for ISO 26262 safety validation; UNECE R155 cyber-resilience tests run nightly. Early integration shaved nine months off Series-C prototype validation, cutting wind-tunnel hours 40 %. Monetization Path
- Data exhaust–heat-map-of-comfort, posture shift trends–feeds subscription wellness analytics for fleets. A ride-hail OEM already charges $4/month for adaptive mood lighting powered by Cabin
