Smart Mobility
Ensuring No Child
Left Inside
by Lindsay Brooke
Up-armed with new key technologies, Gentex is making
'holistic' driver and cabin monitoring a core-brand hallmark.
A step-change in sensing precision is underway
for vehicle interior applications, with increased capabilities
spurred by new technology, customer interest
in occupant safety and entertainment, and global
regulations. Gentex is among those setting the pace in
this fast-moving and hyper-competitive field, as it integrates
its long experience in mirror-based opto-electronic
systems and sensor fusion with the 2021 acquisition
of Tel Aviv-based Guardian Optical Technologies
and the 2020 purchase of Vaporsens.
The Holland, Mich.-based Tier 1 uses the term
" holistic driver and cabin monitoring " to describe the
interconnection of the two main development thrusts.
There is discrete driver monitoring, vital for SAE
Levels 2 and 3 of driving automation, with a subset of
features aimed at driver distraction, drowsiness, weariness,
sudden sickness, etc. And there's the 'holistic'
approach encompassing full-cabin monitoring using
wide-field-of-view (WFoV) imaging as well as sensing
of tactile surfaces and air quality involving particulates
and airborne chemicals.
" As we develop these new capabilities with
Vehicle cabin view, looking backward from the Gentex rear-view mirror
fitted with the new Guardian occupant-sensing tech. The system's micro-vibration
sensing has detected a child's breathing in a 3rd-row seat.
Guardian and Vaporsens, our scalable approach is
opening up opportunities in the cabin, both for AVs
and conventional vehicles, " Neil Boehm, Gentex's
CTO, told SAE Media. He noted that while each
OEM has different motivations for applying in-cabin
monitoring, a new Euro NCAP [New Car Assessment
Program] mandate has the industry's attention. The
ruling plans to add driver/occupant monitoring to
Euro NCAP's 5-Star safety rating, beginning 2022.
And it factors in child-presence detection - a response
by policymakers to heatstroke fatalities suffered by
children left alone in vehicles.
