FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it as a
flat tire.
Functional requirement
In order to ensure that a flat tire is reported cor-
rectly, the system must be initialized while the
tires have the correct inflation pressure.
3.
Start to drive.
The initialization finishes during driving
without feedback.
The initialization must be repeated after
each time the tire inflation pressure is cor-
rected and after every tire or wheel change.<
Via iDrive, for operating principle refer to
page 16:
System limits
1.
Press the
button.
This opens the start menu.
The Flat Tire Monitor cannot indicate sudden
severe tire damage caused by outside factors
and does not detect a natural, even pressure
drop in all four tires.
2.
Press the controller to open the menu.
In the following situations, the system could be
delayed or malfunction:
>
