Traditional fire detection starts at smoke. Underhood starts at risk assessment, hours to days earlier. Edge sensors, maintenance history, and a global incident database combine into a single score for every vehicle in your fleet.
Most operators only have visibility in stages four and five, when flame and smoke have already arrived. The blue zones, where risk is still addressable by inspection and repair, are the zones Underhood is built to operate in.
Hover or tap each stage to see the physical signals, the typical human response, and what Underhood does at that stage.
Electric, CNG, and hybrid drivetrains fail in ways diesel never did. High-voltage arcing, thermal runaway in battery packs, and gas leaks now appear across buses, rail, and marine fleets. Classical fire detection was not designed to see these early signals.
Smoke and heat alarms fire once flames are already present. From flaming combustion to full cabin involvement takes minutes, sometimes less. Evacuation and suppression start from behind.
Chafed wiring, oil mist on hot surfaces, brake grease residue, a missed inspection. Individually minor, collectively the root cause of most fleet fires. Nothing in a traditional workflow is watching the slow curve.
Three data sources in. One 0 to 100 risk score out. Per vehicle, continuously.
Inspections and work orders from your ERP, CMMS, fleet management platform, or data warehouse.
Underhood sensor network or factory CAN reader. Temperature, gas, vibration, current.
Classified fleet fire events worldwide, matched to your vehicle type, propulsion, and age.
Triggered by risk score, sensor thresholds, or both. Admins configure escalation.
Fleet view, risk heatmap, GPS positions, scheduled reports, audit exports for compliance.
Completed inspections and work orders feed back into the score. The model learns.
No rip and replace. Underhood reads from your existing systems and fills the gaps with optional hardware only where you need it.
Connect your ERP, CMMS, or fleet management platform. Inspections and work orders flow in as they happen.
Have a data lake or nightly exports? We pull from it. CSV, JSON, Parquet, or SQL, your format.
We read from your existing IoT/telemetry stack or the vehicle's own CAN bus via certified readers.
Optional. When factory signals are not enough, our ESP32-based sensor kit adds targeted thermal, gas, and current signals for fire-specific accuracy.
