IAV Electrics/ElectronicsTest House
IAV brings together and coordinates all
testing activities under the roof of one
test house. At central level, our com-
pany's quality policy provides the basis for
defining a testing policy which, in turn, is
translated into testing manuals and guide-
lines. These establish uniform and binding
quality standards for all testing activities.
The foundation of the Test House is not only
test management and testing but also de-
veloping test cases and test environments.
It adapts and enhances processes and also
provides coaching tailored to the client's
specific needs.

System or component testing
System and component testing for
automobile manufacturers and
component suppliers are services
from IAV. Automated testing processes and
evaluations permit reproducible test results
in a very short time. System data recordings
provide comprehensive fault documenta-
tion and facilitate fault analysis. Test man-
agement is an important aspect of testing.
To this end, IAV uses, among other test
management tools, the HPTM TestDirector /
QualityCenter and our in-house off-line ver-
sion, IAV Mobile Test. System and compo-
nent testing allow OEMs and component
suppliers to plan their costs.
Electrical/Electronic System Testing
as an All-In-One Service at Fixed Price Packages
Test Domains
and Scope of Electrical/Electronic System Testing
The basis for this is feature and prototype
planning. Our experience in estimating the
cost of testing a system produces firm
prices. Breaking down activities into test
packages, the effect on prices remains
transparent if changes are made to the
overall project schedule.

Today, electrics/electronics extend
into all parts of the vehicle. In addi-
tion to the sophistication of individ-
ual domains it is the complexity of
distributed systems which is constantly in-
creasing. Therefore, IAV always regards the
vehicle as a whole, both at the early stage of
development and during test procedures.
This is where our engineers demonstrate
their expertise in the overall vehicle.
Our services in electrical/electronic
system testing
• Functions
• FailSafe
• Software
• Control units
• Energy management, quiescent current
• Interfaces
• Buses (CAN, LIN, FlexRay, K-Line etc.)
• Diagnostics (ODX, UDS, KWP, OBD etc.)
• Protocols (network management, TP,
BAP etc.)
• Environment, EMC

For a large part, electrical/electronic
functions are realized through the in-
teraction of distributed components
(several control units, sensors/actuators,
operating and display de vices). In this
context, individual components provide
sub-functions (e.g. speed sensing) and
resources (e.g. display field, computing
capacity) that are used by several distrib -
uted functions (e.g. ACC or ESP interven-
tion). As part of system integration testing,
distributed functions are checked for their
operating and failure behavior within a
nearly realistic component network. Before-
hand, those components had been vali-
dated at other test stages.
Beyond this, the interaction of features
sharing the same components is tested in
order to achieve a certain intended interac-
tion (e.g. mutual interlocking) and exclude
unintentional reactions (e.g. blocking a
warning device). In addition to validating
functional behavior, particular significance
is attached here to the detectability of mal-
functions as well as to behavior in response
to typical disturbances (e.g. in relation to the
voltage supply).
Tailored to your requirements, IAV
can provide the following services:
• Designing the validation process at com-
ponent, sub-system and system level
• Performance of validation processes for
vehicle projects:
- Coordination of system integration
process
- Planning, setting up and operating test
environments (e.g. domain HIL, network
HIL, laboratory vehicle)
- Generating and updating test catalogs
- Implementing automatically executable
test cases
- Defining the test scope for user accept-
ance test on vehicle (intensive vehicle
test)
• Testing, tracking anomalies and rectifying
faults

IAV can offer you comprehensive expert-
ise in testing and validating distributed
driver assistance systems based on en-
viromental sensors. Here, we attach particu-
lar importance to using efficient test design
methods, testing procedures and testing
tools that are geared specifically to the par-
ticular test objective concerned. Partially or
fully automated solutions are used for
larger-scale or frequently recurring test ac-
tivities. Flexibly configurable HIL simulators
are available for this purpose. All activities
are supported by comprehensive require-
ments, test, valida tion and problem man-
agement. This way, the development
process remains transparent for you as the
customer from the requirement to the test
result.

Electrics/Electronics – Test Examples
To adapt and test parking assistants,
IAV has developed a test bench to
measure the detection properties of
typical environmental sensors in an auto-
mated and reproducible way. The aim is to
assess these properties of ultrasound-
based sensors at all stages of the produc-
tion-vehicle development process.
The sound radiated from the sensors has a
substantial influence on the system proper-
ties of parking assistants. In order to in-
clude, for example, the effects of mounting
position, angle of incidence and sensor
holder in the measurement, result sensors
are installed during tests as closely as pos-
sible to the way in which they would be in a
production vehicle. For testing, various test
objects, such as the replica of a roadside
guide pole, are made to traverse paths run-
ning vertically to the contour of the vehicle
with the aid of robots. In addition to the en-
tire vehicle, it is also possible to test front
and rear ends separately. To ensure fault-
free operation of the parking assistant, the
vehicle’s electrical system is in this case
substituted for rest bus simulation. To simu-
late reproducible enviromental conditions,
measurements can also be conducted in
climate chambers.
Among other sources, signal output to the
driver serves as measurement data. These
signals are measured in the vehicle and au-
tomatically displayed in graphic form in rela-
tion to object position. This is necessary
from the user’s point of view in order to ob-
tain an OEM-independent system assess-
ment of the vehicle feature. Using these

is possible to produce conclusive evalua-
tions very quickly.

Radio test drives, navigation field
tests and the testing of system sta-
bility form an important part of sys-
tem testing. For this purpose, IAV has a
comprehensive catalog of routes for Euro-
pean-wide test drives. Testing also involves
the use of IAV measurement systems.
Navigation Field Tests/ Country-Specific Road Tests
Prominent testing points to validate the
functionality of navigation, radio or tele-
phone features are elements of the route
catalog.
Voice Laboratory
The technical realization of voice-process-
ing systems in motor vehicles differs de-
pending on the objective (e.g. telephony,
communication inside the vehicle, control
or exchanging information). From the
consum er’s point of view, however, all so-
phisticated systems come with fundamen-
tal demands regarding voice quality. In view
of rising quality demands, the necessity of
measuring the voice quality reproducibly
has never been greater.
In view of rising quality demands, the ne-
cessity of measuring the voice quality of the
particular system under analysis reliably and
on a reproducible basis has never been
greater.. This is the only way to verify in-de-
velopment changes for their efficacy, per-
form target/actual comparisons, analyze
faults or compare competitor products.
Voice and Audio Laboratory
At IAV’s Voice Laboratory, these quality cri-
teria can be measured objectively in test
processes developed in-house.
Audio Laboratory
The audio laboratory is optimized for sound
reproduc tion and is extensively equipped
with measuring systems. It is specially
equalized for assessments according to D.
Clark.

into three areas
• Electrics: load tests, pulse strength, im-
pedance, harmonic distortion test
• Mechanics: climate, acceleration, pres-
sure, tightness, dust

Active and Passive Safety
Achieving the targets derived from
accident statistics for reducing ac-
cident numbers demands a combi-
nation of passive and active safety
measures. Passive safety electronics prima-
rily focus on minimizing accident severity.
Active safety electronics widen the field of
effective action through to the point of
avoiding accidents.
Active safety electronics rely on a broad
range of sensor information from the vehi-
cle and its surroundings. The many potential
traffic scenarios along with the amount of
information to be processed lead to spe-
cific requirements on testing and validation
of such complex safety systems. The depth
of testing required in this context can only
be achieved with the support of special
simulations.
To optimize the protection given to vehicle
occupants in case of an accident, active
and passive safety electronics have to meet
the highest requirements on reliability. The
complex electronics are checked in system
tests by automated and thus reproducible
test procedures. Targeted and tool-aided
methods of analysis can quickly localize
and report on problems occurring.
IAV's range of activities in the field of safety
electronics covers the entire bandwidth be-
ginning with individually planned and exe-
cuted system tests up to a complete
system integration.
IAV can offer its clients the following
benefits
• Ensuring conformity without tying up OEM
resources
• Fusion between “active“ and “passive”
safety
• Reproducible test procedures
• Specification and setting-up of
test facilities
• Simulating scenes for inclusion in

In modern vehicles, system information is
transported via data bus systems. IAV
conducts conformity tests in the power-
train and comfort domain on behalf of
OEMs and component suppliers to validate
distributed functions. This testing work
checks adherence to formats and fault
mechanisms at all levels from the physical
layer to higher protocols, such as network
management, TP and KWP2000. Testing is
partially automated. The test methods and
automatic testing equipment used are certi-
fied by the OEMs and constantly adapted in
consultation with them. As a result, our test
reports fully meet with our customers’ ap-
proval.

Today’s infotainment components not
only contain analog amplifier stages
but also a variety of signal and micro-
processors. Among other functions, these
take care of controlling devices, signal pro-
cessing and CAN communication.
On starting the engine, vehicle voltage can
drop to a critical level, restricting the func-
tion of devices and resulting in undefined
operating states of devices. This test
checks the required system stability after
the starting pulse has expired. Given the de-
vices’ different operating states (e.g. AM-
FM, audio CD, navigation system use) as
well as the variance of the test pulse, each
device under test often demands more than
1000 measurements.
The vehicle power supply generator in use
possesses the necessary circuitry topolo-
gies, such as the voltage supply of the de-
vice under test as well as a system for
absorbing energies fed back from the test
set-up.
Test features for minimizing testing
effort per test specimen
• Computer-controlled test procedures
• Automated generation of result documen-
tation
• Flexible adaptation and extension of test
parameters to accommodate new test cy-
cles

The consumption of electrical energy
in a vehicle is responsible for a signifi-
cant share in a vehicle’s total fuel
consumption. In view of legal and social de-
mands to reduce CO2 emissions and with
respect to the growing electrical energy
needs of power control and comfort sys-
tems, the layout of electrical systems for
optimised energy consumption will play a
key part in developing future vehicles.
IAV tests, measures and analyses the quies-
cent current consump tion and energy bal-
ance of the overall vehicle, control units and
individual electrical components. The aim of
the analyses is to identify measures for op-
timizing electrical power consumers and
energy management. To assess the energy
balance of vehicles, indicators are deter-
mined for rating the correlation between
electrical energy consumption and benefit
to the consumer.
Test planning
• Listing and grouping of power consumers
on the basis of technical vehicle docu-
mentation
• Preparation of a measurement plan
• Straightforward connection of measuring
transducers to the vehicle’s electrical sys-
tem by means of fuse adapters
• Straightforward extension and configura-
tion of measurement blocks of up to 96
channels
• Fitting out the vehicle with measuring
equipment, stripping measuring equip-
ment from the vehicle
Quiescent current measurement,
energy analysis
• Quiescent current measurements on the
overall vehicle with one or two-battery
electrical systems and also high-voltage
circuitry
• Analysing the share in total quiescent cur-
rent consumption per single component

The installation and distribution of
electronic components in vehicles
has seen a dramatic rise in recent
years. This is also accompanied by an in-
crease in the probability of malfunctions
and thus also in the work involved in fault
analysis. Evaluating malfunctions demands
more and more measurement data – some-
times making it necessary to record all vehi-
cle communication.
The data gathered are automatically evalu-
ated by IAV’s AMeDA software. It can be
used for importing and analysing all meas-
urement data commonly encountered in the
automotive field. A high level of perform-
ance is ensured as data can be accessed
through the local file system as well as
through a global network. On top of this,
large files and volumes of data can be
processed quickly and with effortless ease.
Test features:
• Platform-independent as programmed in
Java
• Easy processing of very large traces
• Parallel search for defined events
• Multiple-processor systems support
• Configuration and result generation by
means of XML files
• Support of all common vehicle
measurement data formats
• Modular approach for flexible extension
IAV’s portfolio covers services for monitoring
and operating test fleets with a view to col-
lecting and evaluating measurement data of
this type.

Based on the test processes them-
selves, IAV works with an established
tool architecture. In addition to the
usual standard tools, we use IAV-developed
tools to provide our customers with opti-
mum support. Open interfaces ensure
seamless integration into the client's
processes and tools. Exchanging individual
tool components is not a problem either.

IAV's TestSuite is an in-house tool that
supports the "test implementation" sub-
process. The consistent use of XML pro-
vides open formats for test projects,
including process information and configu-
ration data. Open interfaces for import/ex-
port filters and test components through an
add-in concept permit integration into any
process and test environment (e.g. Quality-
Center). Test components allow communi-
cation with any hardware and software. Test
projects can be conducted on a flexible
basis in different environments with differ-
ent levels of automation without changing
the test specification. Test reports and pro-
tocols are generated “by the flip of a switch”.

For test management to be effective in
the automotive industry or other sec-
tors of industry with mobile testing
needs, the functionality available in the on-
line system must be provided by an off-line
client.
IAV has developed the IAV MobileTest soft-
ware for this purpose. With this tool, fea-
tures relevant for testing can be used
off-line as well.
The IAV MobileTest software supports the
entire spectrum of testing and fault pro-
cessing. New test cases added while test-
ing is in progress can also be processed
off-line at any time.

Comprehensive and clearly struc-
tured documentation of faults oc-
curring in test drives makes it easier
for the software developer to analyze them.
IAV has developed the IAV MultimediaLog-
ger for this purpose.
Frequently, deficits in functionality and sta-
bility after a test drive are no longer repro-
ducible because information is not available
on the test driver’s operating and those re-
actions from other control units which have
thereby been set in motion. The IAV Multi-
mediaLogger permits the automatic and
synchronous recording of data from differ-
ent control units. This provides the capabil-
ity of studying the root of a fault in detail.
Functions:
• Tool for recording audio, video, GPS, CAN
and mobile telephony data
• Tool for selecting and downloading cho-
sen databases from the recording tool’s
overall stock of databases
• Tool for the audio-visual playback of
recorded data
Hardware:
• Laptop with FireWire card and CANcardXL
• Two FireWire cameras with lenses
• Microphone
• GPS receiver
• Remote control
• Case
• Two camera mounts
