Tesla HW4.0 Upgrades Near‑Infrared Broad‑Spectrum Sensitivity, Enhancing FSD Perception Robustness for All Driving Conditions

Pure‑vision autonomous driving solutions have long faced insufficient perception accuracy under extreme scenarios such as rain, fog, night, backlighting and strong light. Traditional RGB cameras feature limited spectral coverage and weak identification capability under harsh weather. Tesla upgrades Sony‑custom global‑shutter CMOS sensors in its HW4.0 autonomous‑driving hardware platform, expanding the 400‑1000nm visible‑to‑near‑infrared broad‑spectrum sensitivity range with improved dynamic range, greatly enhancing target‑identification stability under extreme conditions. Adhering to the pure‑vision route, it realizes all‑scenario perception upgrades for high‑level autonomous driving.
