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

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.

Our services exemplified by info-

tainment system testing

• Test project and test management

• HMI testing (structure, layout, colors,

fonts, symbols etc.)

• Functional testing from the aspect

of the client

• Testing of navigation, telephone, radio,

DAB, CD/CDC/mp3, antennas etc.

• Distributed functions

• Diagnostics, software downloads

• Internal system functions

(clock, language etc.)

• ON/OFF behavior, starting pulse

• Endurance testing

• Data logger for fault documentation and

analysis

• Project-related test automation and sys-

tem integration tests

Processes

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

11

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.

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.

Testing activities at our

Audio Laboratory

• Analysis and measurement of

audio systems

• Audio recordings and playback

• Processing of audio signals

• Component simulation

loud speak er component testing according

to technical specifications of OEMs.

The audio testing activites can be divided

into three areas

• Electrics: load tests, pulse strength, im-

pedance, harmonic distortion test

• Mechanics: climate, acceleration, pres-

sure, tightness, dust

• Material: resistance to reagents,

vibrometry

Radio Laboratory

The laboratory is equipped with a

measurement rack and tools devel-

oped in-house for verifying the char-

acteristic electrical data of radios.

The radio laboratory station fea-

tures the following components:

• Several test transmitters

• 2-channel analyzer

• Radio interface box with load simulation

• Control computer

• Supply devices

• Test speakers

UKW, MW, UHF, VHF, DAB, DVB-T stationary

antenna signals are available for connec-

tion. Various models have been developed

to provide the capability of simulating test

drives in the laboratory.

A comprehensive test catalog forms the

basis of automated, partially-automated

and manual tests. The results are analysed

and displayed.

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

HIL/SIL Tests

Focal aspects of testing active

safety

• Pre-crash

• Predictive pedestrian protection

• Scene simulation using the

IAV Scene Suite

• Test set-ups for non-destructive collision

testing

Focal aspects of testing passive

safety

• Airbag control units with and without

roll-over sensing

• Occupant detection systems

• Sensor signal analysis

• Test automation for airbag electronics

• Pedestrian protection electronics


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

• Measurement of operating current of indi-

vidual components up to approx. IQC

[1000 A]

• Measurement of quiescent and operating

currents of control units and electrical

components

• Simultaneous recording and evaluation of

CAN and LIN communication

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.

Range of fleet testing services

• Planning the test fleet

• Constructing/modifying/maintaining

vehicles

• Fitting out with measuring equipment

• Hardware and software version

management

• Operating vehicles with a domain-specific

focus

Analysis of DistributedControl Unit Systemsand Fleet Testing


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
