2.1 Introduction

The term "Telematics" is a combination of the words "Telecommunication" and "In-formatics". Telematics indicates the possibility of processing information and trans-porting it over a distance at the same time.

Telematics, as an application in the commercial vehicle industry, makes it possible to transfer data and information that is sensed in the trailer to a computer via a wireless connection for further processing. Normally, the access to the information occurs via an Internet portal.

Utilisation of this information is complex and depends on the business processes of the user.

Areas of use

The range of applications for a Trailer Telematics system can be:

• Location-detection for the trailer

• Documentation for the condition of goods, such as e.g. the temperature in the trailer

• Monitoring of the technical characteristics of the trailer, e.g. the tire pressures

The Trailer Telematics System is designed for geographical Europe (including Tur-key). Operation of TrailerGUARD is only possible in areas with GPS- and mobile reception.

The area of application for the Trailer Telematics system is mainly dependent on

the technical boundary conditions, e.g. the GSM coverage in the respective coun-tries.

2.4 Configuration / Power supply

2.4.1 Trailer EBS / ABS

The power supply via terminal 15/30 through the Trailer EBS is implemented by the POWER / EBS slot on the TTU. This slot is also used to transfer the CAN data to the Trailer EBS.

Corresponding modulator parameters generally need to be defined for the correct

power supply of the TTU, siehe publication „TrailerGUARD – System Descrip-tion“ => chapter „Installation of the TTU“.

In this regard, always observe the documentation of the respective manufacturer for the modulator and strictly follow the specifications and instructions!

WABCO Trailer EBS

The WABCO Trailer EBS as of generation D1 Premium supplies the TTU with in-formation on the trailer EBS as well as the voltage. The trailer EBS also transfers data from the tyre pressure monitoring system IVTM and the brake lining wear in-dicator BVA to the TTU via the second CAN bus (5 V).

Modulators of the Trailer EBS of generation D0 (production date up to 09/2003,

serial number up to 75000) do not support the power supply of the TTU can there-fore cannot be used for connecting a TTU.

Please refer to the TEBS E documents for a detailed description of the TEBS E

system.

WABCO Vario Compact ABS (VCS II)

The WABCO Vario Compact ABS "VCS II" allows operation of the TTU without a 5 V CAN interface. However, no CAN data (e.g. loading and brake lining wear) is transferred from the VCS II modulator to the TTU.

The vehicle speed and the odometer reading are determined by the TTU on the basis of the received GPS data.

System

2.4.2 TTU battery

The TTU battery supplies the TTU with power, if the trailer is disconnected and the TTU is not supplied via terminal 15/30. The TTU battery is charged through the TTU when the power supply is connected.

2.4.3 Refrigerator battery

In addition to or instead of the TTU battery, the battery for the refrigerator can also be used to supply the TTU with power when the ignition is switched off.

The refrigerator battery is not charged by the TTU. This causes the danger of run-

ning down the battery if the refrigerator is not run for longer periods of time.

To prevent this discharge, the telematics system is equipped with a preset under-voltage limit for the refrigerator battery. When the value drops below this limit and the TTU is also equipped with a TTU battery, the TTU disables the refrigerator bat-tery as a power source and supply is continued from the TTU battery. Only when there is sufficient voltage available again is the battery used as a power source for the TTU again.

2.4.4 Vehicle electrical system

The vehicle electrical system (12 V or 24 V) can be used as another power source, connected to the POWER/EBS slot on the TTU.

The TTU can also be connected directly to the vehicle electrical system of a vehi-cle such as e.g. delivery vehicle or passenger vehicle. Prerequisite for this is a constant supply voltage via terminal 30 (even with ignition OFF). There is no re-quirement for using a TTU battery this way.

This configuration is not suitable for a trailer vehicle however, since the constant power supply via terminal 30 is not assured when the trailer vehicle is not con-nected.

If the vehicle electrical system is used as a power source, no CAN data is available

on the trailer EBS.

Connecting the TTU directly to the power supply of the ISO 7638 plug connection (ABS/EBS connector) is not permitted according to applicable regulations.

3.1 Trailer Telematic Unit (TTU)

Purpose

The TTU is the central component for Telematics in trailers. It handles the following tasks:

• Collecting and temporarily storing the data from the individual system compo-nents and sensors

• Managing the individual tasks for reading, temporarily storing and transferring the data.

• Bidirectional communication between the Telematics Portal and the vehicle.

• Determining the position using a GPS signal. Coordinating the operating modes and the power supply of the LIN sensors.

Function

Operating modes

The TTU can switch operating modes for extending the standby time with discon-nected trailers. The TTU chooses the respective operating mode automatically, however, many components may not be available depending on the mode of op-eration.

Interfaces

The TTU has three interfaces for connecting components and sensors:

Interface Slot Description

CAN 1, OPTIONS 3, POWER/EBS

Interface to the Trailer EBS or other CAN-capable modulators (slot 1) and for diagnosing via CAN (slot 3). Downstream from the trailer EBS are diagnostic port, IVTM and BVA.

LIN 2, BATTERY 4, LIN

Interface to battery, door- and coupling sensor and the LIN-based sensors. The individual sen-sors are connected with Y-distributors.

RS232 1, OPTIONS Interface to refrigeration system and to diagnostics. The information of the cooling device is transferred directly via the temperature logger.

3.1.3 TTU battery

Purpose

The TTU battery supplies the TTU with power if the TTU is not supplied via termi-nal 15/30.

Function

The TTU battery is charged through the TTU when the power supply is connected.

In exclusive battery operation, the TTU can be supplied with voltage for approxi-mately 8 weeks. The duration depends on the application conditions and the in-stalled components and can greatly deviate from this value.

Notes for battery operation

The TTU battery has logic that protects it from deep discharge. As soon as the voltage drops below a defined value, the battery switches off automatically. It is ac-tivated again by the power supply of the TTU through terminal 15 / 30.

If the TTU has switched off for self-preservation, the TTU cannot record, save or

send any data via terminal 15 / 30 if no power is supplied.

CAUTION

Damage to the battery cells due to lack of charging – Completely charge the TTU battery even when not used (e.g. putting the trailer

out of service for a longer period) no later than after three months.

By charging the battery you avoid irreparable damage to the battery cells.

The maximum storage duration of the TTU battery is 1 year from the production date. WABCO provides no guarantee for the TTU battery after the storage time elapses.

3.2.1 Door sensor

Purpose

The door sensor detects by means of the magnet whether the door is open or closed.

The door sensor can also be used to sense the tailgate on a dumping body or a box with fittings.

Function

The door sensor is a non-contact switch, consisting of a hall sensor and a magnet. Up to 4 door sensors can be connected to the TTU. The door sensor detects whether the door is open or closed by means of the magnets and sends the door status and a change of the door status to the TTU. In the Telematics Portal, the status "Door open" is indicated as soon as one of the doors has been opened

Each door sensor is recognised via its own ID in the LIN bus. Therefore, when us-ing multiple door sensors, different item numbers have to be used. The door sen-sors must be used in combination with magnet 446 290 261 0.

Thermo King "SmartReefer 2"

The i-Box supplies the temperature data of the SmartReefer 2 from up to 4 sensors and the corresponding Set Point values (may. three) to the TTU. In addition, the re-frigerator status, information on the defrost cycle, refrigerator service messages and the diesel engine's operating hours are transmitted to the TTU and displayed in the Telematics Portal.

If the refrigerator is switched off, the i-Box does not send any data of the refrigera-

tor to the TTU. The message Temperature monitoring not possible appears in the Telematics Portal in this case.

Carrier "Data Cold 500"

The "Carrier Data Cold 500" temperature logger can be used for temperature moni-toring in combination with the TTU.

Data Cold 500 supplies temperature data from up to 4 sensors and the corre-sponding Set Point values (max. three). In addition, the refrigerator status, informa-tion on the defrost cycle and the electric motor's and the diesel engine's operating hours are transmitted to the TTU and displayed in the Telematics Portal.

Data Cold 500 uses a special algorithm for data processing that, when there are

great temperature fluctuations, can result in deviations between the temperatures indicated in the display of the Data Cold 500 and those in the Telematics Portal or the diagnosis.

Connection

– Connect the temperature logger to the OPTIONS slot on the TTU.

3.3.2 Cooling unit

In addition to the data from the temperature logger, cooling device data (e.g. Set Points or messages) can also be sent to the TTU. This is only possible however if the temperature logger supports this option and a data line is installed between the cooling device and the temperature logger.

Up to 3 Set Points can be processed and transferred by the TTU. The temperature loggers listed in the table below support the transmission of data from the cooling unit. The scope of data is different however and depends on the system used.

3.3.3 Refrigerator battery

Purpose

In addition to or instead of the TTU battery, the battery for the refrigerator can also be used to supply the TTU with power when the ignition is switched off.

The refrigerator battery is not charged by the TTU. This causes the danger of run-

ning down the battery if the refrigerator is not run for longer periods of time.

To prevent this discharge, the telematics system is equipped with a preset under-voltage limit for the refrigerator battery. When the value drops below this limit and the TTU is also equipped with a TTU battery, the TTU disables the refrigerator bat-tery as a power source and supply is continued from the TTU battery. Only when there is sufficient voltage available again is the battery used as a power source for the TTU again.

When connecting the refrigerator battery to the TTU, a 5 A fuse is to be installed in the + line

4 Communication and the Telematics Portal

Besides the components in the vehicle, the Telematics system also consists of the data transmission, the data management and the user interface. The data man-agement and user interface are combined in the Telematics Portal or the API inter-face. The data transmission occurs in the background and can only be influenced indirectly.

The communication between the vehicle and the Telematics Portal occurs at fixed intervals and in the case of a message from the connected sensors or components (event-based) via the mobile phone network.

The communication between the Telematics Portal and the Telematics user takes place via the Internet. The notification for defined events is implemented via e-mail and SMS and can be freely configured in the Telematics Portal.

4.3 API interface

WABCO TrailerGUARD provides an interface for application programming, abbre-viated as. This interface allows use of online services to transfer telematics data to an ERP system or other software for direct further processing.

The API is included in all service packages so that telematics vehicle data can also be used separately from the web portal. A Pull-API (to retrieve telematics data when requested) and a Push-API (to obtain telematics data automatically) are sup-ported.

The implementation of a Pull-API client is described in the TrailerGUARD SOAP-API documentation, which can be obtained from WABCO Service administrator@wabco-telematics.com and also includes the configuration files "API.wsdl" and "API.zip".

A description of the implementation of a Push-API client, also including the configu-ration file "PushAPI.wsdl" is also available.

A Java client can be used to set up API and a data connection.

The following items relate to the API service and it is essential to take them into account:

• Java environment: http://java.sun.com/downloads/index.html

• ANT: http://ant.apache.org/bindownload.cgi

• AXIS: http://ws.apache.org/axis/

• WSDL file with definitions (<HTTP address>/api/API.wsdl)

• Javadoc for API (<HTTP-address>/api/doc/index.html)

• Login and password for using API (identical to the login for the web portal)

• IP address (name of the computer) and port for API users
