The California car maker wants permission to use unlicensed millimeter-wave sensors that would operate at higher power levels than allowed under existing rules.
The radar-based system “provides depth perception and can 'see' through soft materials, such as a blanket covering a child in a child restraint”. Radar imaging, Tesla adds, can assess body size to optimise airbag deployment in a crash depending on whether an adult or child is seated, which it says would be more effective than existing weight-based, in-seat sensor systems.The FCC is seeking public comment on Tesla's request until September 21.
