The van that can't see its own blind spot: why commercial-vehicle ADAS lags passenger cars
We keep shipping passenger-car ADAS with five-star NCAP banners, then bolt a cheaper, narrower-aperture camera onto a delivery van and call it "commercial-grade." It isn't. The failure-mode distribution on a 3.5-tonne van pulling a 1.2-tonne trailer is not the same problem as a sedan on a Euro-NCAP test track.
The regulation is real but narrow. UN R151 (direct vision) and the EU General Safety Regulation blind-spot mandate push OEMs toward camera-monitor systems and moving-off information systems (MOIS, R159). Good. But the spec asks "does it detect a pedestrian at the kerb?" It does not ask "does it still detect them when the trailer articulates and the camera's ground-plane assumption is off by 40 cm?" That is exactly where vans and trucks hurt people — low-speed manoeuvres, not highway lane-keeping.
Edge cases I actually see in fleet data:
1. Trailer articulation breaks the homography. A fusion stack that trusts a fixed camera-to-ground...
