dependable. " He said that will come from a combination
of technology, consumer trust and dependable
electronics. " The other underlying topic to solve is
to make the systems safe, secure, and highly available, "
Schaefer added at the conference. " If we have
a wonderful Level 4 system and it's not available,
consumers will ultimately lose trust in new systems. "
Stefan Poledna, CTO of TTTech Auto, added that
the ultimate path to public trust is to demonstrate
that automated vehicles are safer than human drivers.
Current system abilities are good, the speakers agreed,
but to get to 100% reliability " might be a long journey, "
Schaefer conceded. Nonetheless, Indu Vijayan, director
of Product Management at AEye, a developer of software-defined
lidar sensing, said she believes Level 4
automation will be available for private vehicles in a
decade or sooner.
Hardware, software and systems
Asked whether hardware or software improvement
is more crucial to advancing high-level vehicle automation,
the panelists weren't in agreement, effectively
saying that both are important. " It's a very holistic
approach to get a system that is dependable, " stated
Infineon's Schaefer.
Vijayan offered data about how perception-system
performance is advancing to provide more sophistication
- and margin for safety. She said that 120 to 160
meters (394 to 525 ft.) is now the target for " seeing a
small object at long range " for highway-oriented Level
4 automated driving systems. Several automakers
currently market " hands-off " driver-assist systems
designed largely for highway driving, but all are Level
3 category - meaning that although the system will
accelerate, decelerate and steer the vehicle, the driver
must at all times be prepared to take control if necessary.
In addition to vehicle OEMs and technology suppliers, The Autonomous
ecosystem invites stakeholders from governmental, academic, regulatory and
standardization institutions to ensure an integrated approach to the various
autonomous-mobility safety challenges.
This distinction is one that Vijayan said is
important, noting that system limitations need to be
clearly defined for end-users. A recent study released
by the Insurance Institute for Highway Safety (IIHS)
supported this point, finding in a survey of 600 users
of various automakers' ADAS systems that those users
had " poor understanding of the technology's limits, "
according to IIHS President David Harkey.
The panel agreed that safety considerations should
not be dictated by any specific strategic choices about
hardware, such as chipsets, or software - and that a
guarantee of system safety shouldn't be regarded in a
competitive sense but in a collaborative framework. " It's
very clear that we need to have redundancy; no single
chip, sensor or software component can do it alone, "
