IVTM
stands for Integrated Vehicle Tire Pressure
Monitoring. It is the tire pressure monitoring system,
which is installed in the vehicle.
IVTM
continuously
monitors the pressure in all tires. This monitoring is
performed by the pressure sensors in all tires, which
relays information to the display in the cabin and warns
driver about critical pressure drop.
IVTM
makes transport
safer and more efficient, because more than 80 % of tire
damage could be recognized before serious damage
occurs, which requires repair.
IVTM
thus cuts down
operational costs, as continually maintained optimized
pressure in all tires results in minimal fuel consumption
and extension of service life of tires.
Let us present some information:
Tire manufacturers estimate that total losses caused by
improper maintenance of tires of commercial vehicles are
more than 10 millions of Euro in Germany. Lot of vehicle
users unfortunately tend to overlook this important factor
of operational costs. By selecting correct tires and proper
maintenance it is possible to save up to 2500.- €per
vehicle for one year. The unnecessary expanses are
further increased by widely spread carelessness of
driving with under-inflated tires. Tires with 20 % lower
pressure are no exception in everyday life. This under-
inflation reduces service life of tires by 20 % and
unnecessarily increases fuel consumption.
In order to minimize these costs WABCO company
designed new system IVTM, which also increases traffic
safety.
