Vehicle Dynamics Testing

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

Standard Vehicle Test Maneuvers

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

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

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.
   

Vehicle Test Suite Application

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).

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.
