Road Load Data Acquisition highlights

Any Sensor Connection

Virtually any analog, counter, and digital sensor can be connected and data acquired synchronized down to microseconds. Measure vibration, strain & stress, voltage, etc.

Simple MTS Controller Integration

Any SIRIUS data acquisition system equipped with an EtherCAT interface can use EtherCAT and USB interfaces to provide real-time data to a 3rd party control system (MTS) and full-speed data to Dewesoft X software in parallel.

Other Data Sources

Additional synchronized acquisition of other sources is possible within the same system - CAN, CAN FD, GPS, GYRO, OBDII, J1939, FlexRay, XCP/CCP, Video, etc.

High-channel DAQ Systems

The system can easily be scaled from 8 to 1000's of channels.

High Isolation

All inputs offer high ±1000V galvanic channel-to-channel and channel-to-ground isolation to prevent ground loops and keep the maximum signal quality.

Sampling Rate up to 1MS/sec

Analog inputs are available with a simultaneous sampling rate of up to 1 MS/sec per channel.

High Dynamic 160 dB

Our highest-performing SIRIUS waterproof offers dual 24-bit ADC with a high dynamic range of 160 dB in time and frequency domain.

Anti-aliasing Filter

All input offers high-quality 24-bit aliasing free sampling.

TEDS sensor support

Our data acquisition systems utilize TEDS sensor technology in compliance with the IEEE 1451.4 standard. Sensors equipped with TEDS are automatically recognized and configured within our software, enabling zero configuration by default.

One DAQ System for Road and Lab Testing

R8rt system and SIRIUS modular can be used to record the data on the real roads or proving ground and also in the lab to replay the recorded data on the road simulator. Included EtherCAT slave port can feed the data to any EtherCAT master controller in real-time. The solution offers very easy integration with an MTS road simulator with one cable only.

Additional Analysis

Possibility to combine different applications and analyses with the same system. Vehicle dynamics, combustion analysis, vibrations, etc. are just a few applications that can be combined with the same solution in one synchronized data file.

Export Data

The software exports data in several formats like RPC III for use with testbeds or for additional post analysis in Matlab, Excel, Diadem, FlexPro, FAMOS, UNV, and others.

Software included

Every Dewesoft data acquisition system is bundled with award-winning DewesoftX data acquisition software. The software is easy to use but very rich and deep in functionality. All software updates are free forever with no hidden licensing or yearly maintenance fees.

Dewesoft quality and 7-year warranty

Enjoy our industry-leading 7-year warranty. Our data acquisition systems are made in Europe, utilizing only the highest build quality standards. We offer free and customer-focused technical support. Your investment into the Dewesoft solutions is protected for years ahead.

Durability Testing Overview

Road load data acquisition (or RLDA) is an excellent method for measuring precise vehicle response. It takes into account all types of essential vehicle and driving parameters, such as mass, inertia, air and rolling resistance, road characteristics, engine loads, and vehicle speed. These road load data are used to derive a durability target.

A road load data acquisition system is capable of recording the data during real test drives under extreme conditions. Various smart technologies ensure to avoid re-runs and shorten the time of testing dramatically.

Our road load acquisition system can be extended to thousands of channels and is capable of recording analog, digital, counter, CAN, CAN FD, XCP/CCP, FlexRay, Video, GPS, and many other data other sources, all inside a single box with perfect synchronization. Virtually any sensor can be connected and acquired during the drive.

The system is very easy to install, and configure and is ready in a matter of seconds after the sensors mount. Highly reliable and sophisticated DAQ hardware offers "worry-free" measurements.

Compact All-in-one Data Acquisition Systems

The R8 line of data acquisition instruments offers high channel count in a very compact and robust chassis. It also features built-in SSD data logging and a powerful data processing computer in a single box. The system can be powered directly from the vehicle battery and/or can be optionally configured with an internal high capacity Li-ion battery for maximum reliability.

The system can be configured with up to 128 analog channels, 64 counter channels, 192 digital channels, 8 CAN ports, a 100 Hz GPS sensor, and 64 analog outputs.

Dewesoft X software offers additional acquisition of CAN, CAN FD, XCP/CCP, FlexRay, GPS and Inertial measurement units, multiple video cameras, gyro platforms, and wheel force transducers - Kistler KiRoad.

Powerful Data Acquisition Software

Award-winning Dewesoft X software provides powerful and easy-to-use measurement and analysis features:

sensor autodetection with TEDS,
sensor database,
automatic unit conversion,
automated sensor balancing,
shunt calibration to quickly check the measurement chain of bridge amplifiers,
powerful storing capabilities - continuous, triggered on events, etc.
raw data storage,
online visualization and validation,
powerful analysis features and data export to several standard file formats.

Digital Interface to 3rd Party Durability Test Benches

R8rt and SIRIUS DAQ systems include dual EtherCAT and USB data interfaces. DAQ systems can feed real-time data to a 3rd party control system and record full-speed data to Dewesoft X software in parallel. This makes our durability recording system unique and allows the DAQ system to be used directly in the control loop and as a DAQ recording device at the same time.

DAQ systems can provide acquired samples in digital form to the test bench control (such as MTS road simulator) if it supports the EtherCAT interface. This reduces a cost for the customer dramatically as the solution requires only a single cable from our DAQ systems to the test bench controller. It also eliminates the need for a high-level analog input stage on the controller side. Slide the photo right to see the number of cables eliminated at one of our customers by replacing the existing system with our R8rt instrument.
