Objective

TCE

1

In modern motor vehicles the onboard information for
drivers becomes more and more extensive. In future
drivers will be able to read information about truck and
trailer via a display on their dashboard They will get this
information via data buses, i.e. via communication
connections between different electronics having a CAN
interface. As a result the connected electronic systems
will be able to exchange, evaluate and further process
information. In future lighting on vehicles will also be
controlled via data buses and errors will be displayed in
trucks.

Trailers will be included in this exchange of information
via a 7-pin ABS/EBS plug connection acc. to ISO 7638
and in parallel via a 15-pin plug connection acc. to
ISO 12098. In both cases the data connection
corresponds to ISO 11992 part 1.

By a consequent use of the available data connections
between motor vehicle and trailer WABCO creates the
precondition for new innovative vehicle functions while
at the same time the number of the required electrical
connections is limited.

In summary the objectives are as follows:

 System data bus in trailers

 Integration of trailers into the motor vehicle

system

• Limitation of number of electrical connections

• Extension of the motor vehicle system functions

to trailers

 Integration of trailer system functions

• Level control and lifting axle control

• Ramp approach help

• Lighting control

• Telematic connection

• Additional functions

TCE II

Modifications due to the introduction of TCE II are
marked in the following text in expanded type.

• New trailer system functions via data exchange

• More simple realisation of current system

TCE

Objective

1.1 Concept and Realisation

As trailer central electronic TCE enables the
communication between motor vehicle and trailer res.
motor vehicle and trailer systems. Moreover TCE
supports the connection of intelligent individual systems
in trailers to a powerful system like in the towing vehicle.
TCE itself assumes the following electronic and
electrical functions:

 Electrical supply of trailer systems including battery

supply and battery charging equipment. With a trail­er battery diagnostic and ramp operations are pos­sible without a motor vehicle.

 Motor vehicle - trailer communication for brake and

”running gear“ systems (ISO 7638), as well as for
general vehicle systems (ISO 12098). ”Running
gear“ means components concerning the driving
safety, e.g. chassis, tires, steering and suspension.

 Trailer data bus for EBS, running gear, tire systems

and vehicle systems with separate CAN connec­tions. As a result an exchange of electrical consum­ers and transmission of information via data
connection is possible.

 Future central diagnostic connection for TCE and

all systems connected via CAN. Future diagnosis
from the motor vehicle is provided (e.g. via an on­board display).

 Brake lining wear sensing system with up to six

sensors.

 In future reading and processing of analogue and

digital information will be possible.
e.g.
Programmable inputs and outputs for recording of
switch positions and analogue values, as well as for
controlling modulators and additional lighting. Indi­vidual customer modules will be created by
WABCO. These are adjustable via diagnosis.

 Integrated electronic level control (ECAS) for semi-

trailers and trailers with one or two level sensors.

 Integrated electronic lift axle control with automatic

functions as traction help, load dependent lowering
/ lifting and manoeuvring aid.

 Ramp approaching help with automatic braking

when backing and approaching the ramp.

 Electronically secured lighting control and monitor-

ing with status reports to the motor vehicle.

 tire pressure recording and tire pressure monitoring

with connected IVTM system.

 Service support (operating hours counter, mileage

counter, electronic notebook, battery hours coun­ter).

The following data can be transmitted to the motor
vehicle provided the respective system is installed:

• Axle loads:

• Tire pressure values

• Status of vehicle lighting

• Distance to ramp

• Brake lining wear

• Status of ramp approach help RAH

• Lift axle status

Under same conditions as in the motor vehicle the
following data can be transmitted to a telematic system:

• Error in lighting

• Error in RAH function

• Vehicle stopped before ramp

• Service date achieved

• Vehicle overloaded

• Red /yellow/green warning light

• Axle load

• Tire pressure values

• Error in RAH function

• Vehicle hitched/unhitched

• Battery status

• Vehicle door open/closed

• Operating hours

• Mileage

• Brake lining wear

2.1 External Communication
Possibilities

When a telematic system is connected to the TCE
location of the vehicle resp. recall of vehicle specific data
is possible.

The following transmission systems can be used:
 The Global Positioning System, shortly called

GPS, enables identification of the vehicle position.

 The Global System for Mobile Communication

(GSM) enables wireless data transmission. Thus
remote diagnosis will also be possible in future.

 The 'Short Range Communication' is only possible

in the yard near a correspond. transmitting / receiv­ing station.

TCE

General

The different systems may be used from trucks with
trailer connection or separately on trucks and on trailers
(e.g. for cooler and service information).
Thus the carrier resp. the controller can check for
instance position of the vehicle, temperature of the
cooling system and state of the vehicle. On short term
he may have the vehicle turned around and pick up
another load. In case of vehicle problems the controller
can inform a nearby repair shop in advance about the
vehicle state and can care for spare parts if required.

Telematic problems can only be corrected by the
respective telematic manufacturer in his service
repair shops.

2.2 Standards

TCE observes the following standards:

TCE II

Telematic systems in trucks and trailers can retrieve
more special information from the TCE II.

– event and profile data
– Service schedule
– Vehicle master data

Telematic systems in trailers will automatically be
informed on additional events

– Vehicle door open/closed
– Vehicle hitched/unhitched
– Tire pressure changes
– Service intervals etc.

Do not open the electronic remote control unit!

All terminals have to be closed.

All plug in connections are marked with an X and a
number and fitted with special locking clips. To connect

a cable, it is necessary to fold up the locking clip, push
in the plug and then close the locking clip.

Since the terminals are located very close, cables
should be plugged into the electronic in the order from
X11 to X41, X12 to X42, etc.

The front of the electronic consists of coded plug-in
terminals and thus is protected against interchange of
plugs. Unused terminals have to be closed by means of
cap 894 110 139 2.

TCE I:

A maximum of two pressure sensors can be connected
to the TCE. The 1
has to be connected. Among others is is used for axle
load calculation for the trailer EBS system.

pressure sensor (1st PS) always

TCE II

For the TCE II system it is not compulsory under certain
circumstances (dependent on the connected EBS
modulator) to connect one or two pressure sensors.

The required pressure sensor signal is directly sent from
the EBS modulator (D version) to the TCE II. If the ECAS
is to actuate a lateral or a drawbar trailer control, a
pressure sensor can be connected to the TCE.

If two pressure sensors are to be installed, the red
marked cable end is to be connected to the pressure
sensor (2
The blue marked cable end is to be connected to the
pressure sensor (1
