Virtual Calibration in Non-Standard Conditions

Increase Quality and Reduce Effort With AVL Virtual Testbed™

With our Virtual Testbed we have created a testing environment that is capable of replacing in-vehicle or testbed setups. This provides our engineers with an additional environment to comprehensively test different system configurations.

Virtual Testbed

The Virtual Testbed is a testing solution that allows you to connect models to your control units for virtual testing and calibration. How does it fit into your established development processes? Simply use the same tools, development environment and testing workflows as your other testing facilities. How does it connect to the “real” world? Move some of your test cases and calibration tasks (up to 30 %) to the Virtual Testbed. Rely on our proven and tested use cases for optimal guidance.

Testing and validation is an expensive and complex activity. This calls for large numbers of prototypes, along with costly test trips to examine the capability of systems in different climatic regions. Even mitigating these costs by switching much of the test burden from on-road and on-vehicle to climatic testbeds can be costly. Testbeds, that accommodate tests within the relevant range of non-standard ambient conditions, often come with huge hourly costs. A solution is therefore vital, to manage the performance and the cost efficiency.

Meeting New Trends

Stringent emission and CO2 regulations drive the development of new propulsion concepts.

Variety Of Variants

The variety of different powertrain and vehicle variants is increasing.

Based on more than 10 years of experience using Virtual Testbeds in calibration projects at both AVL and our customers, the solution is ready to support your:

  • Engine development (e.g. calibration at non-standard conditions, robustness investigations)
  • Powertrain development (e.g. shift strategy optimization)
  • Hybrid systems development (e.g. optimization of operating strategies,  integration testing)
  • Fuel cell development (e.g. calibration at non-standard conditions)

Already applied in hundreds of development projects, our virtual testbed covers:

  • Passenger cars
  • Light-duty and medium-duty vehicles
  • Heavy-duty vehicles
  • Off-road machinery

Validated use cases are available for all of these configurations.
