Tesla Inc. requested the Federal Communications Commission (FCC) for permission to market a close-range interactive motion-sensing device that could be helpful in avoiding children from being left behind in hot cars and encourage theft-prevention set-ups.
The California based auto manufacturer seeks consent to use unlicensed millimeter-wave sensors that would function at better power levels than the ones permitted under present regulations.
Tesla’s device would make use of four transmit and three receive antennas powered by a radar front-end unit. Tesla even states that its millimeter-wave radar technology has several benefits compared to the other sensing systems like the camera-based or in-seat occupant detection systems.
Considering the radar-based system, it “provides depth perception and can ‘see’ through soft materials, such as a blanket covering a child in a child restraint.”
Tesla further added that it “can differentiate between a child and an object left on the seat, reducing the likelihood of false alarms” and that it can even identify “micromovements like breathing patterns and heart rates, neither of which can be captured by cameras or in-seat sensors alone.”
Tesla even states that its radar imaging can evaluate body size to maximize airbag deployment in a crash hinging upon whether an adult or a child is seated, which Tesla mentions that would be more effective in comparison with existing weight-based, in-seat sensor systems.
This new system would even correctly assess when exactly to involve seat-belt reminders.
The FCC is on the lookout for public comment on Tesla’s request through Sept 21.
