Tire Pressure Monitoring System
Electronic Tire Pressure Monitoring System
More mobility. More safety. More comfort.
1. lntrod uction
The vehicle tire and thus the tire infla—
tion pressure is one of the few safety-
reIevant factors in a vehicle which are
not subject to permanent control.
Despite that the tires hold one of the
first positions among the technical
reasons for accidents with personal in
jury or severe material damage in the
accident statistics of the German
Association of Automotive Manu~
facturers.
Former attempts to introduce systems
for tire pressure control were not
successful due to either the insuffi-
cient functionality [electromechanical
threshold value systems), or excessive
costs (inductively coupled measuring
systems]. It was only in the last few
years that the progress in the miniatu—
rization of electronic parts and the
increase in the capacity of batteries,
allowed the development of electronic
battery-powered sensors which are
installed in automotive tires and
transmit data by means of high»fre-
quency transmission. Tire pressure
monitoring systems based on this
principle can be made at costs which
allow a wide distribution in passenger
cars.
in 1992, the car manufacturers AUDI.
BMW, DAlMLERfBENZ, PORSCHE and
VOLKSWAGEN established a work-
group for the development of a tire
pressure monitoring system, with the
target of defining a standard for basic
functions to create the preconditions
for an economical system by means of
standardization of the components. in
1995, the project partners ALLIGATOR —
valve and housing engineering — and
BERU — electronic and connection en-
gineering ~ were entrusted with the
development of the system which is
now ready for series production,
BERU was given responsibility for the
system.
2. Description of Function
2.1 An Overview of the Function
The tire pressure monitoring system is
applied for the permanent control of
the tire pressure during driving and
also during standstill periods.
An electronic system which is installed
in the interior of the tire measures the
tire pressure and the temperature i
regular” intervals and transmits infor
mation to a central control unit by‘
means ofa high—frequency transmissi» ‘
on line. The control unit evaluates the
incoming data and transmits the
information to the driver, if required.
In the case of a puncture, the driver is
given a warning, and he is also infor~
med when the tire pressure should be
corrected.
The advantages of this tire pressure
monitoring system are:
I Safety
An early warning is given in the case
of slow loss of pressure. The bursting
