Automated Driving Is Transforming the Sensor and Computing Market
currently being delivered to OEMs including
BYD, Arcfox, BMW and Mercedes.
Eyes-off driving applications are not as
simple as just adding more sensors and com-
puting power to the car. They are also linked
to a new generation of more performant
sensors that can detect smaller objects at a
greater range.
Cameras are improving not just in res-
olution, with 8-MP image sensors being
embedded, but also in terms of dynamic
range, so that low light and intense light are
less of an issue. Twelve-megapixel image sen-
sors have appeared, and discussions are being
held on future design wins. Radar is evolving
from legacy radar, with its range, Doppler and
azimuth capabilities, to 4D radar, which offers
an additional, elevation capability. And imag-
ing radar now offers better angular resolution
and the ability to track more objects.
Eyes-off driving applications
are not as simple as
just adding more sensors
and computing power to
the car.
Finally, LiDAR is emerging quite rapidly,
and its performance is increasing, especially
its range and resolution. The latest LiDAR
technology will be able to generate up to
12 million points per second to enrich the
point cloud.
Despite this new generation of sensors,
eyes-off driving remains exceedingly chal-
lenging for the handful of OEMs engaged
in this direction. As already mentioned,
they will be responsible during automated
driving. Therefore, they are restricting the
operational domain design to ensure safety.
The current use case is highway driving up to
