Measurement
The tire pressure is measured by sensors. The measured values are repeatedly
transmitted to the electronic control unit by radio signal.
The actual tire pressure of each wheel is transmitted to a central ECU. The
signals of all wheels are evaluated there and the information is conveyed to a
display in the driver's cab.
Evaluating
In the ECU, the measured values are compared to one another and to standard
values stored as a parameter set in the ECU.
A single OptiTire
TM
ECU can monitor up to 20 2 spare wheels. Dual
tires are sensed separately.
A warning is signalled in the event of a critical deviation.
