State-of-the-Art Prototyping

  Product Brochure PROtroniC LINE

The classic development of a control unit with the associated software costs a lot of time – and, of course, a lot of money. Especially if concept errors are only discovered later and therefore hardware, software and possibly even system components have to be re-engineered at great expense.
With the PROtroniC, Schaeffler Engineering has created the revolution in the field of vehicle technology, thus significantly accelerating the development of mechatronic systems. This is because new approaches to solutions can be quickly and simply evaluated and secured using the flexibly adaptable prototyping control unit long before the series control unit is available.

Using the PROtroniC, customers work with a model-based tool chain which is also suitable for series development – from the graphics modeling and simulation and automatic code generation right through to calibration of the control algorithms and functions.

In this way, a smooth transition takes place from the prototyping phase to series development – and ideas are brought more quickly to the road.


What makes the PROtroniC LINE special

System Architecture


From ideas come automobiles

In order to simplify the everyday work with the PROtroniC, the development environment of PROtroniC units is based on the widespread tools used in the automobile industry. In this way, developers not only have the possibility to freely select the code generator, but also the existing measurement and application tools:

Model-based function development

Graphic modeling of the control functions with

  • Simulink®
  • Stateflow®

Offline Simulations

Testing and optimization of draft functions against a controlled system through offline simulations at the computer with

  • Simulink®
  • Stateflow®

Hardware Mapping

A link between the inputs and outputs of the function model and the PROtroniC control unit via an application controller interface for

  • Simulink®

Auto Code Generation

Automatic generation of efficient series codes and, if required, with

  • TargetLink®
  • Embedded Coder™


Download of the generated software via the supplied boot loader. Testing and verification of new functions on the test bench, in the vehicle or via hardware-in-the-loop simulation.

Measurement and application

Fine tuning and measurement of the control software with

  • MARC I
  • INCA
  • CANape

Arrive safely at your destination

The PROtroniC connects prototyping with series development. And with optimum safety – thanks to the unique "Safety on Board" concept:

  • A multi-stage monitoring system guarantees the realization of user-specific safety functions during prototyping.
  • Only development tools are used that are compatible with ISO 26262.
  • Enables the conception of safety-related functions in a model-based development environment.
  • Supports the realization of user-specific safety functions already during prototyping.
  • Helps to build an optimal system safety for fleet and road tests.
  • Offers one tool chain for everything – from prototyping to series production.

This sets you off on a safe journey in the direction of series production!
