SAE International Sections

SAE International Sections are local
units comprised of 100 or more SAE
International Members in a defined
technical or geographic area. The purpose
of local Sections is to meet the technical,
developmental, and personal needs of the
SAE Members in a given area. For more
information, please visit sae.org/sections
or contact SAE Member Relations Specialist
Abby Hartman at abby.hartman@sae.org.

SAE International
Collegiate Chapters

Collegiate Chapters are a way for SAE
International Student Members to get
together on their campus and develop
skills in a student-run and -elected
environment. Student Members are vital
to the continued success and future of
SAE. While your course work teaches
you the engineering knowledge you
need, participation in your SAE Collegiate
Chapter can develop or enhance other
important skills, including leadership,
time management, project management,
communications, organization, planning,
delegation, budgeting, and finance. For
more information, please visit students.

Heavy-duty trucks still are disproportionately
involved in deadly crashes on U.S. roadways.
" Ten percent of the fatalities involve large
trucks when large trucks only account for 4%
of the registered vehicles, " Kevin Chronicle,
who's responsible for commercial-vehicle strategy in North America for Bosch, said at the
2021 SAE Government/Industry Digital Summit.
New accident research from Bosch reveals
that equipping heavy trucks with advanced
driver assistance systems (ADAS) such as lateral actuator systems may significantly reduce
the costs of accidents influenced by heavy
trucks. Lateral actuator systems are ADAS solutions that provide automated steering input for
functions like Lane Change Assist (LCA) and
Lane Keeping Support (LKS).
The Bosch accident research, " Safety +
Enhanced Driver Comfort: Steering in Commercial
Vehicle ADAS Systems, " finds that lateral actuator
systems in Class 7 and 8 trucks can reduce the
costs of accidents by up to $0.04 per mile, or
$3,700 annually per heavy truck.
" Increasing levels of automation and driver
assistance help to reduce accidents and make
drivers' lives easier, " said Kevin O'Keefe, regional
president of Automotive Steering for Bosch in
North America. " The Bosch accident research
findings illustrate how features like Lane Change
Assist and Lane Keeping Support can contribute
positively in multiple ways - reducing property
damage, injuries and fatalities. "

Calculating Field of Effect

The Bosch accident research reviewed public
crash data to identify correlating statistics between vehicle types and the severity of crashes. This data was utilized to calculate a Field
of Effect (FoE) for accidents involving large
trucks. To calculate FoE, crashes were examined that could have been mitigated or avoided by using lateral actuator systems - more
specifically, LCA and LKS.
Based on the accident research, the data
shows injuries from Class 7 and Class 8 truck
crashes could be reduced by up to 23 percent
and fatalities by up to 19 percent when they
are the accident-triggering vehicle. LCA and
LKS systems also could reduce the property
damage from Class 7 and Class 8 trucks by up
to 35 percent.
The introduction of Level 2 steering systems
in North America in 2020 aims to make roadways safer. Safety features such as hydraulic
failure detection and added steering assist can
support the driver during hydraulic failure or
drastic events like tire blowouts. Systems that
provide active pull compensation, active steering damping, and reduced steering effort also
help to increase driver comfort in the cab.
" With active pull compensation, let's say
you're driving down an embankment for an
extended period of time. The steering has a
smart algorithm to learn that and adjust - less
strain on the driver, " Chronicle said.
