With car sales plunging, demand for automotive
electronics is dropping as well. Only Electronic Stability Control
(ESC) systems sales seem to be braving the dip and are expected to
generate attractive opportunities for suppliers of
Microelectromechanical Sensors (MEMS). MEMS find use in ESC
systems, which build on Anti-lock Braking System (ABS) technology
by correcting vehicle direction to help drivers maintain control
of their vehicle during rapid steering and counter-steering
changes, which may occur during events like sudden lane changes or
swerves to avoid obstacles.
With worldwide penetration of ESC technology in
new cars will grow to 57 per cent in 2012, up from 28 per cent in
2006, according to research findings from iSuppli’s report
entitled: Mandates Reshape the Market for Electronic Stability
Control Systems. This is attributed mainly to government mandates
requiring stability control in the United States and later in
Europe.
Sources at iSuppli express that government
mandates on ESC should provide opportunities for at least six
players new to the ESC market, either in development or sampling
gyroscopes, and likewise four companies developing product for
accelerometers. While new offerings are expected to begin in the
truck market before attacking the large automotive OEM, it is
companies like VTi, Bosch, Mobis, Systron Donner and Panasonic,
which are expected to gain the most.
VTi specialises in accelerometers, which
measure the measuring lateral slip. VTI Technologies, which
supplies all the MEMS accelerometers used by Continental
Automotive Systems, was the accelerometer market leader in 2007
with a 53 per cent share of industry revenue. Bosch was second,
supplying accelerometers for its own systems and to Mobis. It held
a 29 per cent share of ESC accelerometer revenue in 2007. In the
gyroscope (yaw rate measuring device) market, Systron Donner was
the market leader with a 44 per cent share of market revenue in
2007. The company was the only supplier to Continental Automotive
Systems, with its high-performance quartz tuning fork design.
Bosch was second with 30 per cent of revenue due to sales of
gyroscopes for its own ESC systems. Panasonic, which held the
fourth place for ESC gyroscope revenue in 2007 managed to surpass
Silicon Sensing Systems in terms of unit shipments in 2007, giving
it the No3 ranking based on volume.
Bosch led the pressure sensor market in 2007
with 54 percent share of revenue. Sensata, a 2006 spin-off from
Texas Instruments Inc., stood second with a 34 percent share of
revenue. Denso was a distant third.
