2. Configuration
In order to display tire pressure and trailer warnings to
driver during driving it is in general case necessary to
install IVTM to both parts of vehicle, i.e. one control unit
to trailer and one unit to motor vehicle. Any vehicle
equipped with IVTM could be connected to any trailer
equipped with IVTM. Control unit of vehicle identifies
control unit of trailer automatically: Synchronization is
ensured through the break lights wiring, data are
transported wirelessly.
As trailers are usually not permanently powered, it is
possible that due to the frequency of wheel modules
transmission the tire pressure data for all the wheels
could be available after up to 15 minutes after the drive
start.
In combination with WABCO-TCE (Trailer Central
Electronics) or EBS systems the information about the
pressure could be transmitted into control unit through
standardized bus connection CAN according to 11992.
Future vehicles will be able to display the data from CAN
bus on multifunction display on the dashboard. If such
vehicles will not be available, data will be transferred to
the vehicle control IVTM unit wirelessly.
Certificates
Certificates for mounting and additional mounting of
IVTM are available, which significantly facilitate approval
of vehicle registration papers. Certificates are not part of
this booklet, however in case of need they could be or-
dered in WABCO or by Internet at www.wabco-auto.com
