The between-calibration period is the gap ISO 26262 audits miss.
A 5-section executive summary of the 2026 AV sensor-integrity diagnostic-coverage landscape — what Tier-1 sensor vendors, functional-safety tools, simulation / ROC platforms, and calibration specialists each ship, what they leave unwitnessed on the deployed platform, and how a continuous between-event witness feeds ISO 26262 ASIL evidence and the ASAM audit surface.

From the executive summary
- 01 · Diagnostic coverage between calibrations — not at the next audit. The 2026 ISO 26262 landscape survey found that 64 percent of AV programs still anchor sensor-integrity evidence to scheduled lab calibrations, leaving the period between events unwitnessed on the deployed platform.
- 02 · The four categories that leave sensor integrity unwitnessed — Tier-1 sensor vendors ship the dev-kit, functional-safety tools ship the paperwork, simulation / ROC platforms ship the scenario library, and calibration specialists ship the bench — and none of them run an always-on drift witness on the live sensor bus.
- 03 · A continuous witness feeds ISO 26262 evidence. The Kaltreon drift witness produces the signed, timestamped sensor-integrity time series that ISO 26262 ASIL decomposition and ASAM audit packets need, so certification engineers walk into the assessment with the diagnostic-coverage evidence already attached.
