system INTEGRATION As a vehicle manufacturer or supplier, you are supplied with ECUs by several companies. You would like to integrate these ECUs in the vehicles overall structure, assure their functions, and make sure that they can be integrated with other ECUs. Each step in your process ends with a test before the next step is started.  The connection between your ECUs and the PC is made via a FlexCard ( page 36). We can offer you different variants of these interface cards.  One big vehicle manufacturer already uses Caromee ( page 32) intensively to test and integrate the electrical and electronic components in the overall system. The range of applications includes Reference project: ACTIVESOUND ECU

The amplifier controls a speaker coupled to the exhaust pipe. The whole system can be integrated into test vehicles of OEMs. The OEMs can create their own sound characteristics via the FlexSound PC software. So this ECU allows to modify especially the sound of Diesel driven vehicles to let them sound more powerful. In a next step a sound cancelation feature will be integrated into the ActiveSound ECU.

ecu lab testing

Development Test bench In your development planning, you have identified the need for a component test bench. We support you in design, development and implementation of test benches. If you wish, we can take your existing systems into consideration.  For the connection between your test bench and the FlexRay and/or CAN bus of the test device we offer the FlexCard PMC and PMC II ( page 36). These fit in a mezzanine slot, and provide with multiple FlexRay A/B and CAN high-speed channels. For PCI systems, there is a PCI and PCIe adapter available. Integration in your test bench is possible with our FlexCard drivers for Windows, Linux and LabVIEW ( page 40).  As part of a test bench project, we provide optimal operating and evaluation software that is oriented towards your needs for efficient test bench utilisation.  For your Hardware-in-the-Loop (HiL) test bench we provide support for network, diagnostics and electrical tests. We integrate 3rd party equipment (e.g. LabVIEW) and develop custom hardware and software for your specific use case. Our solutions include CAN and FlexRay bus access, simulation and test. Starting in the concept phase we provide turn-key-solutions for your development testing needs.

Reference project: PORTING THE REmaining BUS SIMULATION For a large automotive supplier, we have integrated our remaining bus simulation in the real-time operating system of the companys test bench hardware. With the help of a remaining bus simulation configuration generated from FIBEX or AUTOSAR, our customer can test his development and series ECUs on his test benches. The customer can now make the adaptation for new ECUs or ECU variants themselves. The flexibility thus achieved speeds up development and significantly shortens the time taken for adaptation to changed software variants, for example.

One channel is the clock-master and the other FlexRay channel is synchronized to the first channel. With this synchronization the gateway provides deterministic routing times. When separating an ECU from the rest of the network the gateway is configured automatically using a FIBEX File and naming the ECUs to be separated.

caromee - network analysis

Caromee is a software product that provides the basic functions for measuring and analyzing networks in vehicles. It has a large number of open interfaces in several directions, thus reconciling individual requirements with high cost-efficiency. It can not only be adapted to different interface hardware from different manufacturers, but also integrated in existing process sequences and can have specially adapted evaluation functions added on. Whether on a test bench in the car plant or with special laboratory vehicles, Caromee helps you to acquire network data in many areas of vehicle development. Application / solution DATA ANALYSIS Because of the elaborate networks in test vehicles, you will receive a very large volume of data, and this has to be processed and evaluated. Both online and offline evaluations are possible. The MessageViewer provides comprehensive functions for displaying messages in a list. Convenient navigation, filter and search functions for the message lists, which can be very long, make it easier to work with the lists. The diagram display allows graphical presentation of signals. It is possible to show a time-correlated, graphical display of different signals, even from different busses. Signals are represented graphically in one diagram or separately. Time differences can be measured in the graphical signal display.

Caromee TopEd

FAST ONLINE DATA MEASUREMENT You will often want to make a quick measurement on a cluster. With Caromee, guided by a wizard, you can carry out measurements on CAN or FlexRay clusters with little configuration effort. The MessageViewer provides comprehensive functions for displaying messages in a list. Sophisticated filter functions from bus level through message level down to bit level are also part of Caromee.

caromee - network analysis

Application / solution logging In vehicle tests, the main task is to process and evaluate the very large volumes of data that are generated in the test vehicle. This requires a logging tool that supports the engineers in a purposeful manner. Unexpected errors in the vehicle are possible at any time, so all the data that is exchanged in the course of test drives must be acquired, if possible. This allows you to investigate the data deliberately for defects, without having to take a further test drive with the vehicle. Caromee is capable of displaying all the data that have been acquired in the vehicle over a long period in a clear format in the form of a “log”, and of clearly marking events such as error frames or changes of terminal status in it. Further important features of the tool are the analysis filters, because they not only enable you to search a log for certain events. They also allow you to store only

certain data when filling the log, because the interesting events in particular can be associated with a large number of coupled conditions.

FlexOpto optical


PC system

galvanic isolation FlexOpto can be used as galvanic isolation for FlexRay, CAN or LIN networks. Areas with high voltage can be isolated and groundshifts


can be eliminated. Measurement equipment can be protected and the operator is safe because of the non conducting connection.

PC system

range extender



FlexOpto works as a range extender for FlexRay, CAN or LIN



networks. It avoids reflexions because of unterminated tabs or



distortion, e.g. caused by magnetic fields from electric motors etc.

up to 100 m



Because of the optical connection, the signal is not affected.


The optimal solution for your business.
