Tyre pressure
monitoring systems provided by the car manufacturers are not
always the driver's most advantageous solutions. These
systems evaluate tyre pressure relative to the other tyres
on the vehicle. So, if all four tyres were subjected to the
same irregularity, nothing would be detected. The new
Pirelli system, on the other hand, monitors each tyre
individually, providing the most accurate and efficient
detection system.
Usually linked
to the size of the tyre: they do not evaluate directly, but
relative to a comparison with the other tyres fitted to the
vehicle. With the result - improbable, but technically
possible - that if all four tyres should be subjected to the
same anomaly at the same time, that fact would not be
diagnosed. The Pirelli systems work by surveying the tyre
pressure directly and are divided into various systems. The
company puts its weight behind each one. The important new
development starts on the basis of the long studies carried
out by Pirelli. But the results are astonishingly new. Pirelli's latest
system, the K-PRESSURE, will be available soon on the
replacement market and is built around a sensor system that
is fitted to the tyre's valve. Inserted into the valve cap,
the mechanism can be used for both conventional tyres and
the Run Flat, and measures the eventual pressure changes in
real time (different caps, dependant on the reference
value). It then communicates any changes in one of three
different ways:
AcousticBlue: signal via wireless link to the mobile phone;
The system incorporates high-tech
valve sensors that communicate with
a mobile phone via wireless link.
After ensuring that tyre
inflation pressures are correct,
the sensors are screwed onto the
valves (replacing the valve
caps). As soon as the car begins to
move, the sensors transmit data
to a mobile phone. In the event of a drop in
pressure, the phone emits an
acoustic alarm and the display
indicates which of the tyres is
under-inflated.
Acoustic:
signal via the onboard electronic management system;
High-tech valve sensors transmit data to the
display/receiver installed in the car. Acoustic and optical
warning as to which tyre is under-inflated. After ensuring
that tyre inflation pressures are correct, the sensors are
screwed onto the valves (replacing the valve caps). As soon as the car begins to
move, the sensors transmit
data via radio frequency to
the display/receiver inside
the car. In the event of a drop in
pressure, the receiver emits
an acoustic alarm and the
display indicates which tyre
is affected.
