Abstract:
In
the
process
of
high-speed
vehicles,
vehicle
speed
odometer
is
important
instrument
driver
to
provide
dynamic
driving
information,
which
directly
affects the running safety of vehicles. The speedometer tradition has two defects: one
is
the
traditional
speedometer
flexible
shaft
driving
the
vehicle
high
speed
running
condition,
the
shaft
rotating
speed,
the
flexible
shaft
steel
wire
stress
limit,
often
resulting in fatigue fracture of the wire flexible shaft, so that the speedometer failure;
two is a flexible wiring is too long due to deformation, appear too large and the motion
lag, lead to dynamic indicating slow or indication error. In order to be more reliable and
timely
to
the
driver's
driving
dynamic
information,
guarantee
the
driving
safety,
the
problem
of
high
failure
rate,
the
speedometer
dynamic
indicating
slow
service
traditional flexible
shaft
driving,
the
use
of electronic technology,
sensor technology
and
computer
intelligence
technology
advanced,
the
improvement
of
the
traditional
odometer is very necessary.
