TECHNICAL INNOVATIONS
He explained that a group of 10 or
more companies, possibly a mix of tool
suppliers and system developers, could
develop common platforms or interfaces
that would help engineers and
programmers integrate data created
using different tools. The need for simplified
data sharing was echoed by other
speakers at the conference.
" The industry needs clear, unambiguous
exchange of data between tools. We need
standards people can trust, and standards
that can evolve rapidly to stay abreast of
technical advances, " said Benjamin Engel,
CTO at ASAM, a standards body.
Digital continuity
As complexity increases, there's a
strong push to ensure that data developed
in one area can be made useful in
others. A strategy that goes from design
to manufacturing to over-the-air
(OTA) software updates is becoming a
necessity. That dovetails with the
growth of design software that addresses
many parameters, such as software,
hardware, mechatronics, testing and
manufacturing.
" Companies need to be able to use
cloud technology to link all the players
together, said Udo Lange, VP digital engineering
and R&D, Capgemini Invent, a
consulting company. " Digital continuity
means not just data collection - companies
need to integrate data for use in
different areas like manufacturing. They
need to integrate everything to their
back-end processes, extending to distribution
of OTA updates that are managed
well and distributed accurately. "
BMW is making standards a centerpiece
of its efforts to reduce complexity;
AUTOSAR and Ethernet are standards
that are seeing increased use at
the automaker. Employing standards
helps in validation and verification as
well as in basic product design.
" The only way to reduce complexity is
REDUCED EMISSIONS
From inventing compression release technology to developing
next-generation valvetrains and advanced braking systems, we
are continually raising the levels of performance - for power, fuel
economy, and reduced emissions - that heavy-duty commercial
vehicles can achieve.
Jacobs®
Cylinder Deactivation (CDA) system aids in meeting stringent
fuel economy standards such as the new ultra-low NOx standards
and drive cycle. Independent testing has shown up to a 25% fuel
savings, a 77% decrease in NOx, and a 12% reduction in CO2
.

with harmonization and standards, " said
Kirsten Matheus, senior expert at BMW
Group. " Without standards, we don't get
the right tools, and complexity rises. "
Several conference speakers noted
that creating and organizing virtual and
DOUBLE ENGINE
BRAKING POWER
Jacobs®
High Power Density®
engine brake offers a 100% increase in
engine braking power at low cruise RPM (1200 - 1400) and has established
itself as an impressive alternative to existing braking technologies. It is a
milestone in the evolution of Jacobs Engine Brake®
