Electronic suspension preferred over conventional suspension in all tested situations
Tenneco Inc. has published results of a
survey showing that consumers experience
a feeling of increased comfort, control
and safety when driving cars equipped
with intelligent (electronically-adjusted)
suspension systems versus the same cars
equipped with conventional suspension
systems. They are also willing to pay
for electronic systems. In the survey,
conducted for Tenneco by TNS Infratest,
94% of sports utility vehicle drivers rated
the overall driving experience with a semiactive suspension system as very good
or excellent, compared with a rating of
73% for passive suspension systems. In
the compact car segment, 86% of drivers
rated their overall driving experience as
very good or excellent compared with
61% for passive systems, while 88%
of upper middle class) segment drivers
rated semi-active suspension systems
as very good or excellent versus 77% for
passive systems. The most significant
improvement with intelligent suspension
systems reported across all segments
➲ CVSA2 is Tenneco’s newest
generation of lightweight
semi-active dampers.
Each damper features two
independent electro-hydraulic
CES valves for the rebound
and compression motions to
provide an increased tuning
range to reach even higher
comfort levels. CVSA2 uses
electronic (CES) valves
developed by Tenneco in
conjunction with Öhlins Racing
was vehicle comfort with road holding,
stability, agility, control and safety all
scoring strongly versus conventional
systems. In addition, the ability to change
the suspension mode at will resulted in a
strong increase in scores for flexibility and
driving fun versus conventional systems.
Following the consumer survey, a series
of quantitative tests by TÜV SÜD using
vehicles equipped with MonroeIntelligent
Suspension confirmed better wheel to
road contact, which helps avoid sideslip
and over steer, especially during cornering
on uneven road surfaces. In more dynamic
driving situations, such as lane changes or
obstacle avoidance, the reduction in body
movement was found to bring greater
stability, which helps increase the feeling
of comfort and safety.
ITWeb Security Summit Spooks the Delegates
The ninth annual ITWeb Security Summit
was held from 27 to 29 May 2014 at the
Sandton Convention Centre, with a stellar
panel of international and South African
speakers bringing their global expertise on
world trends in surveillance and piracy, indepth insights into the failures of the infosec
community, the impact of the Snowden
revelations, and much more. And for anyone
attending the summit the message was
stark and clear: No matter your station
in life, you are being monitored, and you
can basically do nothing about it, except
to know that you are a surveillance target
and that your only defence is awareness
and continuous monitoring of your
system. International keynote speakers
included Jacob Appelbaum, Charlie Miller,
Christopher Soghoian and Haroon Meer.
In addition to the extensive agenda and
interactive workshops, an expo ran
adjacent to the 2014 summit, showcasing
the latest in products, solutions and
services. Endorsed by ISACA and the
(ISC)² Gauteng Chapter, the summit
served as the most important annual
gathering of South Africa’s business
and ICT decision makers with a security
mandate. aBr will be revisiting this
summit in future issues.
