Vehicle Dynamics Testing highlights

Real-time Results

VTS and Dewesoft X software show all validation and visualize results in real-time during the test itself. Additional math or visualizing can be added later in post-processing if needed.

Automated Workflow

VTS offers pre-defined testing maneuvers for the test operator and easy-on screen controls for the operator to configure and run the tests.

Standardized by ISO and ECE

All the available test maneuvres are configured and performed according to ISO and ECE standards.

Automated Results and Statistics

VTS can show a summary table with statistics and can overlay results from a batch of test runs. 

Down to 2 cm Position Accuracy

We offer high-accuracy GPS or IMU (Inertial Measurement Unit) hardware with optional RTK support which offers highest possible velocity and positioning accuracy. 

Several Maneuvers

VTS offers several standard maneuvers like Steady-state cornering, Step steer input, Step steer non-linear, On center sinus steer, Pseudo Random Steer, Pulse Input Method, Slowly increasing steer, Sine with dwell, and more test maneuvers under the development.

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

Vehicle Dynamics Test Suite

In spite of the increasing adoption of virtual analysis tools in the vehicle development process, the amount of testing activity is all but decreasing, due to several reasons:

  • Detailed simulation models require reliable experimental data for validation.

  • The refinement of some vehicle attributes still need the “human touch”, delivered by subjective and objective test and development on physical prototypes.

  • The development and validation of advanced driving functions (ADAS, autonomous driving) still require extensive real-world testing.

In this context, in an extremely competitive global market, the testing process must be extremely efficient, considering:

The Overall Quality of the Measurement

  • Compliance and reproducibility of the test execution

  • Data accuracy: sensors and acquisition system

Cost Efficiency

  • Preparation time: easy vehicle sensor setup and DAQ system configuration

  • Actual test time: optimize the use of the time spent on the test track or on a test rig

Vehicle Dynamics DAQ System Overview

The image on the right shows the Vehicle Testing Suite data acquisition system which consists of:

  • SIRIUS DAQ system: for the acquisition of analog signals and vehicle CAN bus.

  • SBOX data logger and data processing computer: highly reliable SSD data logger and high-performance data processing computer.

  • DS-BP2 battery pack: a battery pack that provides backup power next to car power supply.

  • DS-IMU2 inertial measurement unit: for highly accurate GPS/GLONASS positioning and orientation.

  • DS-DISP-12 display: in-car mountable high-brightness and high-resolution touch-screen LED monitor.

  • Dewesoft X software with Vehicle Dynamics plugin and Vehicle Testing Suite package.

Standard Vehicle Test Maneuvers

Dewesoft Vehicle Test Suite provides easy-to-use automated testing for the following standard test maneuvers:

Test type Ref. standard
Steady-state corneringISO 4138
Step steer inputISO 7401
Step steer non-linearBased on ISO 7401
On center sinus steerISO 13674-1
Pseudo-Random SteerISO 7401, ISO TR-8726
Pulse Input MethodISO 17288-2
Slowly increasing steerECE 13H
Sine with dwellECE 13H
More test maneuvers in development

For every type of test, validation criteria and other objective parameters are calculated and made available as calculated channels in the measurement files.

Data Processing

Dewesoft Vehicle Dynamics plugin is designed to carry on the pre-processing of the raw signals in accordance with the requirements of ISO standards for vehicle dynamics objective data analysis. All the settings can be managed in the Dewesoft setup. The main features include:

Data processing

  • Catalog of standard test maneuvers

  • Management of the coordinate system

  • Filters

  • Compensation of the sensor position effect

  • Compensation of the g-force effect

Measured Data Processing

Coordinate system

Given the details of the input channels, the output channels are calculated in the desired coordinate system.

Filter and synchronization

The input channels are filtered according to ISO 15037-1 / -2 or ECE 13H standards. Known sensor delays are compensated. 

Compensation of the sensor position effect

Given the sensor location, the Dewesoft X Vehicle Dynamics plugin calculates speed and acceleration at the desired reference point.

Compensation for the gravity effect

The Dewesoft X Vehicle Dynamics plugin calculates the roll and pitch angle and compensates for the effect of g-force if the input acceleration is not in the horizontal plane.

Vehicle Test Suite Application

VTS is an easy-to-use test automation tool and test driver interface on top of Dewesoft X Software. It is designed in order to achieve the highest productivity on the test track with the DS Vehicle Dynamics plugin. Main features:

  • Support for the Dewesoft Vehicle Dynamics plugin.

  • Management of vehicle data and sensor coordinates data.

  • International standards or custom test procedures.

  • Dewesoft integrated into the VTS measurement panel.

  • Quick look display of the main parameters and execution check.

  • Automatic test file naming and storing in a custom folder structure.

  • Data overlay and statistics from multiple test runs

  • Modular architecture for easy extension and further customization.

The VTS application manages the configuration parameters of each type of test:

  • Info: basic information about the test.

  • Measurement settings: sample rate, Dewesoft screen ID, subfolder for data storage.

  • Trigger conditions.

  • Execution conditions: the allowed values of the nominal execution parameters, such as vehicle speed, path radius, steer frequency, etc.

  • Validation condition: the admissible threshold values used in the validation check.

  • The user can edit and store the default configuration of each type of test, based e.g. on the type of vehicle (passenger car or truck).

Easy Controls for the Test Driver

Everything that the test driver needs to control is available with a single touch on the bright and in-car mounted display. The test driver just selects the test session and the test maneuver to perform and set the parameters: 

  • Nominal conditions

  • Start / stop storing controls

  • Test setup

  • Test analysis

  • Save/cancel the test file

Right after stopping storing, the test results are available, and the driver can save or discard the data file and continue with the next test.

Wheel Force Transducers Support and Wheel Torque Measurement

Our data acquisition systems offer fully synchronized data acquisition from wheel force transducer systems such as:

  • Kistler KiRoad performance and RoaDyn: wireless wheel force transducers for rotating and stationary applications

  • Michigan Scientific wheel force transducers

Both devices integrate directly into the award-winning Dewesoft X data acquisition system and will synchronize all available data to our analog and GPS data acquisition devices. Channels from these devices will be available as any other channel and can be stored or used for further analysis directly in the software.

Vehicle Dynamics Case Study

This vehicle dynamics customer story tells how Dewesoft and LEANE, helped some friends, working in different departments of a large automotive OEM car maker, to implement new solutions to improve their daily vehicle testing job.

The result of this collaboration was the development of the Dewesoft R2DB data acquisition system and the Vehicle Test Suite software application, both perfectly suitable for different vehicle dynamics tests.

The customer sums it up:

Advantages of our solutions have improved our job, increasing quality, and efficiency in several ways:

  • optimize the time and competence of the people in the team,

  • reduce the vehicle setup time in the workshop,

  • reduce the test time on the track, and

  • increase the reproducibility of the test data.
