Test Automation System for Driveline Testing

STARS Driveline is an integrated automation, acquisition and control system that provides a broad range of application functionality in a single, powerful environment. It has been designed to fulfil the specialist requirements and applications for driveline testing from simple modal testing on two or four wheel drive systems, to RLS simulation or advanced applications such as service load replication (SLR).

STARS Driveline builds on the powerful STARS platform to deliver a flexible, powerful yet simple to use Automation System specially configured for driveline testing. A number of pre-configured display pages are delivered with the system that allows users to interactively control the complete test stand and instrumentation. STARS is able to interface to and control a wide range of intelligent instruments using simple to program test schedules. In addition, STARS has a dedicated real-time Ethernet interface to the SPARC driveline controller.

Under the covers, STARS keeps the central cluster server and all other workstations in the cluster up to date with the latest information and data. This allows you to access the very latest information wherever you are and whenever you want. With a wide range of user-friendly features, STARS can run the most complex of tests with the simple press of a button – making your test operation effective and efficient and above all, reliable. If necessary, STARS can fit your existing testing process, rather than dictate it. It allows you to centrally manage your results, projects, test stands and libraries; move test specimens and instrumentation within a test shop with no reconfiguration and structure your project in the way you want and with the scope of testing that is best for you.

Base product

Multi-configuration test stands

HORIBA can offer the mechanical solutions to handle many different test specimen configurations. This flexibility is also contained in the STARS and SPARC Driveline applications. Changing configurations is simple in both systems – simply select the system configuration in the list of STARS test stands and the configuration for the SPARC system is automatically loaded and run. Editing of the configuration of SPARC is fully supported in STARS using dedicated editors.

 

Real-time Capabilities

At the heart of STARS is a powerful and capable real time system that can operate at frequencies of up to 5 kHz. 

The real-time system hosts:

  • Test Schedules and real-time scripts operating at up to 5 kHz
  • Dataloggers and Data players that can record and replay data at rates of up to5kHz
  • Alarms and events operating up to 100Hz
  • Intelligent instruments drivers
  • Interface to the SPARC driveline controller at rates up to 1kHz
  • Real-time MATLAB Simulink generated models

 

Workflows

Use Workflows to capture your test processes - the key to increasing the repeatability and productivity of your test operations. By encapsulating complex test logic within Workflows, STARS is simple to use all levels of operator. The most complex of testing tasks can be performed with only a small amount of training. Workflows can be created in a very short time using the high level graphical editor.

 

Online Classification

STARS has a built-in Online Classification capabilitie to aid the process of analysing and classifying, in real-time at rates of up to 1kHz, signals with respect to their amplitude distribution over time. To do this the signal range is divided into a fixed number of classes and the number of events is counted for which the signal is level is within each class. Based on this information it is possible to evaluate the underlying characteristics of a signal and make comparisons between different signals. In powertrain testing, online classification gives insight into the degree of mechanical stress to which a test specimen or system is subjected during different duty cycles.

 

MATLAB Integration

STARS can simplify the operation of MATLAB models in driveline testing by providing interface blocks in the graphical workflow toolkit. These blocks allow users to specify which MATLAB model to run, options on the model and can specify the data that will flow into and out of the model. This allows a complete test process to be defined that integrates your MATLAB model and can hide the complexity of its operation from the test stand operator.

 

Instruments and Robots

STARS is able to interface to and control a wide range of intelligent instruments using simple to program test schedules. In addition, STARS has a dedicated real-time Ethernet interface to the SPARC driveline controller. This interface allows the STARS system to read variables and set demands at rates of up to 1kHz. Through this interface STARS can also control gearshift robots in a coordinated manner with the control of the test rig.

 

STARS Benefits

  • Familiar and intuitive user interface– STARS uses common Windows paradigms, such as the shortcut bar and Windows explorer trees, making it easy to use, no matter how infrequently you use the system. This reduces training time and therefore cost.
  • Graphical tools – Intuitive graphical ‘point and click’ user interfaces are used wherever possible. This also reduces training time and therefore cost.
  • Standard Instrument Plug-Ins– Instruments of the same type are controlled from Test Schedules via a common ‘plug-in’, regardless of the minor differences in the underlying functionality of a specific instrument. This allows tests to be designed using simple and familiar commands that are independent from the specific instrument that will be used during the test.
  • Powerful display pages – A number of pre-configured display pages will delivered with the system that allows users to interactively control the complete test stand and instrumentation. In addition by using the simple, graphical editor, users may quickly create their own displays to read and write data as well as control the test stand.
