X-by-Wire Technologies to Digitalise Cars
X-by-Wire Technologies to Digitalise Cars
Imagine this: You are driving up the Alps climbing at 50 mph using your
joystick to steer the car on the sharp corner, you push the sports button
to get the extra power and suddenly on the sharp turn you hit a puddle and
start to skid. Almost instantaneously and simultaneously, the various
sensors in your car feed data into the microcontrollers which transmit
commands to various functions and within milli-seconds, perfectly balanced
brakes applied on each wheel stabilise the car as you skid, damping levels
of the car's suspension reach optimum levels to steady the car, the
accelerator reduces speed instantly (even if your foot is on it) and the
steering automatically corrects itself and helps you bring the car back to
your original driving line.
Thanks to rapid developments in the X-by-Wire technology, driving European
cars will be a lot smoother, safer and easier in the future. According to a
new study in progress by Frost & Sullivan European Automotive team,
X-by-Wire technologies will revolutionise and alter the in-car componentry,
the driving experience and change the landscape of the car industry. Frost
& Sullivan's initial estimates suggests that 40% of cars produced in
Europe by 2010/12 will have almost all X-by-wire technologies aboard. These
are, but not limited to, brake-by-wire, drive-by-wire (or
throttle-by-wire), steer-by-wire, shift-by-wire and damper-by-wire.
Some of these technologies have already achieved good penetration and
others are in advanced stages of development. For example, throttle by
wire, damper-by-wire, clutch-by-wire have been in use for sometime. ABS
brakes with ESP stability control can be classified as the first generation
of brake-by-wire systems. The second generation of brake-by-wire is
expected to make debut next year when Bosch launches its Elektro-hydraulic
braking (EHB) in end of 2001/beginning 2002 on DaimlerChrysler produced
cars. Steer-by-wire systems (Quadrasteer)are expected to be launched by
Delphi in 2002/03. DaimlerChrysler expects steer-by-wire systems in all its
models by 2005. Says Dr Juergen Guldner of BMW, "almost every BMW vehicles
by 2006/07 will be equipped with all X-by-wire technologies starting with
launch of steer-by-wire and brake-by-wire technologies in the next BMW
vehicle generations". The "true" by-wire systems which will eliminate the
need for hydraulic back?up, are expected to make debut from 2006 onwards.
All these technologies not only contribute to safety, stability, reduced
fuel economy and lower value chain costs for vehicle manufacturers but also
reduce the number of traditional mechanical components such as steering
column, brake fluid, etc. and replace them with advanced electronics
including actuators, sensors and microcontrollers. This means good news for
all electronic suppliers. According to Wolfgang Agert and Arthur Kreutzer
of Texas Instruments, "The silicon content in Automotive which is about 5%
now is expected to double to around 10% with X-by-wire technologies. Where
you now need one microcontroller, in the future you will need multiples of
them or a much powerful one". Motorola sees upto 20% increase in their
revenues from this technology.
Frost & Sullivan analysts also perceive a 'jockeying for positions' within
the suppliers. Bosch is expected to consolidate its 2nd position in the
world market through its pioneering role in brake-by-wire and its leading
position in the European market in electric motors, sensors and other
electronic devices. Delphi is the other significant player in this market
with leading position in steer-by-wire systems. Others who are in advanced
stages of development are TRW and Continental Teves. In the
semi-conductors market, Motorola is likely to strengthen its position in
the market over Infineon in Europe. Electronics market leader, Siemens is
also expected to gain additional sales from this technology. Those
suppliers who lack electronic content in their product portfolio are
expected to be involved in host of JVs or mergers and acquisition activity.
Vehicle manufacturers who are expected to lead from the front are the
German manufacturers of the likes of BMW, DC and Audi. The American
companies are the ones being conservative and doing a 'wait and watch' over
their German counterparts.
The road to success for X-by wire is however filled with a lot of potholes.
For the technology to succeed, the cars need higher power and 42V power
systems need to be ushered in. The vehicle manufacturers also need to
settle on one communication protocol. Presently, there are two major
protocols under discussion; Flexray championed by BMW, DC, Philips, Bosch,
Motorola and some others and Time-Triggered Protocol led by Audi, VW and
Tttech Computertechnik AG. The dark horse in the reckoning is TT-CAN.
According to Dr Gerd Teepe of Motorola, "Initial signs are showing that
Flexray will be the leader as it offers both time-triggered as well as
event-triggered functionality".
X-by-Wire technologies are a reality today. A few years back, people would
have dismissed it as fictional stuff. However, success will only come if
the auto industry can overcome the key challenges and co-operate in fixing
standards and specifications.
These findings have been taken from Frost & Sullivan upcoming report,
"European Market for X-by-Wire Technolgies", due to be published in October
2001. Authors: Hester Stolk and Sarwant Singh, Frost & Sullivan, London
