2. Important remarks

2.1 For your safety

Observe the following remarks before you commission

the device. Kistler accepts no responsibility for damages

that could arise from improper use of this product.

Prerequisite for the proper and safe use of the device

is that it be correctly stored, professionally installed and

commissioned, as well as operated as intended and

carefully maintained. Only persons who are familiar

with the installation, commissioning, operation and

maintenance of comparable devices and who possess the

qualicationsnecessaryforthegiventaskmayworkwith

the device.

Mounting a device on a vehicle invalidates the general

operating permit of the vehicle for use on public roads.

Observe the relevant legal requirements!

Do not look into the lamp; there is a risk of eye damage!

The lamp can become very hot; take this into account

when changing the lamp.

If the sensor is operated for a longer period of time, the

sensor head may become very hot, possibly resulting in

burn injuries. This applies in particular if the sensor is

operated in hot ambient conditions.

Do not use any defective or damaged devices.

Makenounauthorizedmodicationsandchangestothe

device and/or its accessories.

Improperinstallationofthedevicewillaectthesafetyof

the vehicle and the occupants! Install the device in such

a way that equipment necessary for the safety of the

vehicle is not impaired or disabled.

2055A_002-860e-10.20Page 6

When connecting to the power supply, data acquisition

and evaluation systems and other usable components,

pay attention to the proper pin assignment and correct

operating voltage.

The sensor and/or sensor components could be damaged

if the sensor is operated for a long period of time in hot

ambientconditions.Switchothesensorifthevehicleis

not moved for a longer period of time.

Only use the original components included in the scope

of delivery.

Should it be necessary to use your own cables, always

pay attention to the correct pin assignment.

Kistler accepts no liability for damages caused by the use

of cables other than those supplied by Kistler.

2.2 Disposal instructions for electrical and electronic equipment

Waste electronic equipment must not be disposed of with

household waste. At the end of its service life, return the

device to the nearest electronic disposal point or contact

your Kistler sales outlet.

2.3 Software upgrades and updates

If Kistler supplies upgrades or updates for embedded

software, they must be installed.

Kistler assumes no liability for direct or consequential

damages caused by products whose embedded software

is not up-to-date.

3. Product description

3.1 General

Correvit S-Motion DTI sensors enable direct, slip-free

measurement of longitudinal and transverse speed as

well as slip angle in vehicle driving dynamics tests.

Due to their properties, the high-resolution variants

(S-Motion DTI HR) are particularly suitable for low speeds

(e.g. industrial trucks, parking tests).

Correvit S-Motion DTI sensors use the proven Correvit

technology. A new algorithm signicantly reduces the

signal noise. This algorithm and the high measurement

frequency of 500 Hz enable a minimal signal delay of 6

ms.

A built-in 5 Hz GPS receiver enables determination of

position data and time. The external magnetic antenna

allowsexibleandquickmountingonthevehicle.

Integrated accelerometers enable the determination

of additional measurands like longitudinal and trans-

verse acceleration of the vehicle. Integrated angular rate

sensors enable measurement of the pitch and roll angle

as well as the rotation around the vertical axis of the vehi-

cle.

Moreover, further signals such as leveled acceleration

or curve radius are already calculated inside the sensor.

A conversion of speed to any point of the vehicle, e.g.

center of gravity or rear axis is possible.

The output of these additional signals provides the option

to perform a large number of measurands required for

drivingdynamicsstandardtests.Thissimpliestheinstru-

mentation of the vehicle and minimizes application errors.

Correvit S-Motion DTI sensors produce unparalleled

accuracy on all standard testing surfaces, even under the

most challenging conditions. They feature high-quality

optical elements, the newest optoelectronical components

and state-of-the-art high-performance signal processing

based on DSP and FPGA’s. Speed and distance informa-

tion is updated at 500 Hz to track every highly dynamic

maneuver.

5. Mounting and connection

5.1 Mounting options

For optimum performance and accuracy, the mounting

distance between the bottom of the sensor (without splash

guard) and the road surface must be in the specied

range (see chapter 4.1).

Fig. 3: Possible mounting positions

longitudinal sensor type

350 mm 350 mm 350 mm

transverse sensor type

Note the mounting direction of the S-Motion DTI sensor:

longitudinal/transverse variant.

In case of rain or snow, mount the sensor at the front of

the vehicle. This will prevent the measurement from being

impacted by splashing water or snow.

No special running-in procedure is necessary!

2055A_002-860e-10.20Page 18

5.3.3 Bandwidth or cut-o frequency

The cut-o frequency of a system is dened as the fre-

quency where the amplitude of the original signal is

reduced by factor 1/sqrt(2) = 0.707.

The bandwidth is the range between upper and lower cut-

ofrequency.

Usually, we are dealing with low-pass lters where low

frequency or DC signals pass uninuenced but higher

frequencies are blocked. In that case the bandwidth is

identicaltothecut-ofrequency.

In case of a sensor - as for example Correvit S-350 - the

main limitation will be the processor cycle rate.

AS-350 sensor with a processor rate of250 Hz and l-

ter deactivated has a bandwidth of approximately 110 Hz.

Theuseofamovingaveragelterwillreducetheband-

width. As a rule of thumb the following formula can be

used:bandwidth=110Hz*4ms/ltertime

On the other hand, without ltering the resolution of the

signals will decrease. So it is only possible to detect mea-

sure signals whose frequency is below the cut-o fre-

quency and whose amplitude is higher than the sensor

resolution.

5.3.4 Filter setting and acquisition rate

If the acquisition rate is lower than the processor rate of

the sensor, the data acquisition system will only pick sin-

gle values from the sensor. To prevent loss of information

andaliasingeectthemovingaveragelterofthesensor

shouldbeactivated.Theltertimeshouldbeatleastthe

time between two acquisition samples. For example, if the

acquisitionrateis100Hztheltertimeshouldbeatleast

10 ms. The same applies if the CAN send rate of the sen-

sor is reduced.
