The concept
The Flat Tire Monitor detects a pressure loss in
a tire based on comparing the speeds of the
individual wheels while driving.
In the event of a pressure loss, a change occurs
in the rolling circumference and therefore the
rotation speed of the corresponding wheel.
This change is detected and signaled as a flat
tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
3.
Begin driving.
The initialization is completed while driving,
without requiring any further input from you.
The initialization must be carried out after
each correction of the tire inflation pres-
sure and after every tire or wheel change.<
Indication of a flat tire
