PROtroniC - Prototyping ECUs for the mobility for tomorrow

From the drivetrain to comfort electronics: with the PROtroniC prototyping ECUs from Schaeffler Engineering, you work completely without complications and keep the serial goal firmly in your sights even during the development of the first prototype. And: You save time and money.

PROtroniC: Rapid Control Prototyping on the Fast Track

With the PROtroniCLINE, 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 PROtroniCTopLINE or BaseLINE, customers work with a model-based tool chain which is also suitable for series development. In this way, a smooth transition takes place from the prototyping phase to series development – and ideas are brought more quickly to the road.

As part of our projects, we as a research institute enter "new automotive territory" on a daily basis. In addition to maintaining sufficient hardware reserves, this requires a maximum degree of flexibility in order to meet the challenges of tomorrow with confidence. Whether in function development or the investigation and application of new hardware components, PROtroniC is the ideal tool for us to reach our goal effectively and reliably.

What makes the PROtroniC LINE so unique

1. Integrated Power Stage Outputs and Signal Conditioning

  • All PROtroniC variants come with extensive integrated signal conditioning and power stage outputs.

2. Customized solutions (HW / SW) for specific applications

  • State-of-the-art FPGA technology for a softwarebased, quick, and easy configuration of the I/Os according to the specific applications
  • Adjustment of the offered hardware modules for customer specific applications

3. "Safety on Board" concept to unite RCP and Functional Safety

  • A multilevel monitoring concept for developing application-specific safety functions in the prototyping system.
  • Use of development tools certified for developing according to ISO 26262.

4. Seamless Tool-Chain from Design to Series Production

  • Development environment based on tools used in the automobile industry for prototyping and series developments.
  • Supporting different code generators and different measurement as well as calibration tools.

The PROtroniC development control unit from Schaeffler Engineering was used in the development and testing of a test fleet of vehicles with fuel cell technology. Due to the limited installation space, special requirements were placed on the compactness of the prototyping control unit. The integrated signal conditioning and power output stages made it possible to meet the requirements for installation space. The necessary number of inputs and outputs for the complex application could also be provided. In order to be able to drive the vehicles on public roads, a multi-level safety concept was developed and integrated together with the BWM Group.

PROtroniC LINE as Engine, Transmission or Universal Control Unit

Engine Management Unit (EMU)

The EMU variant of the PROtroniC TopLINE and BaseLINE supports the development of common combustion engines (gasoline, diesel, gas engines) as well as of alternative drives.

Technical Features:

  • Configurable lambda and knock sensor inputs
  • Real-time combustion process calculation
  • Flexibly configurable crank-camshaft system
  • Support of nearly all electromagnetic injectors
  • Basic models for gasoline and diesel engines available

Transmission Control Unit (TCU)

Designed especially for transmission applications, the TCU variant of the PROtroniC TopLINE, which has been just released, features a new module for controlling transmission valves.

Technical Features:

  • 16 independent current controlled channels VFS (variable force solenoid) or proportional channels
  • Precise current measurement
  • Integrated and configurable PI controller
  • Configurable dither parameters
  • Extensive protection and diagnosis mechanisms

Universal Control Unit (UCU)

As a universal control unit, the UCU variant of the PROtroniC LINE can be used as a "Vehicle Control Unit" (VCU), "Hybrid Control Unit" (HCU) or "Chassis Control Unit" (CCU).

Technical Features:

  • Integrated signal conditioning and power stage outputs
  • Software configurable power stage outputs for controlling established automotive actuators
  • Simplified development of safety related functions with an the optional "Functional Safety" package incl. a multilevel monitoring concept

Highest flexibility with at the same time very good manageability: With the PROtroniC TopLINE used by us it is possible to test and analyse novel control strategies and function logics in real engine operation in a simple way. Schaeffler Engineering's support for all questions relating to engine control and the functional frame is exemplary.

High Performance when it comes to Rapid Control Prototyping

The PROtroniC TopLINE EMU from Schaeffler Engineering used at ABT Sportsline enables efficient pre-development of new vehicle systems and functionalities. In addition, the PROtroniC TopLINE offers versatile interfaces for the analysis of these systems, enabling us to optimally implement internal and external requirements.

The high class of Rapid Control Prototyping

The core of the PROtroniC TopLINE is a real-time processor unit with dual PowerPC architecture, extensive communication interfaces and state-of-the-art FPGA (Field-Programmable-Gate-Array) technology.

A PowerPC processor with 1 GHz processing power and doubleprecision floating-point unit is exclusively reserved for processing the application software. A second processor relieves the main processor from all peripheral and communication tasks.

The processing-intensive and time-critical preparation and pre-processing of the bus, sensor and actuator signals have been transferred to especially configured FPGAs. As a result, the system is not only flexibly adaptable and expandable for future tasks, but also sets standards in terms of processing power.

The basis for best performance in series production

The PROtroniC BaseLINE is the perfect solution for close-to-production working. The heart of this development control unit is provided by the high-performance microcontroller, while various analog and digital inputs provide for perfect connections. Compact, robust and perfect for otherwise costly applications or fleet tests.

As with production control units, a powerful microcontroller of the type Freescale MPC5554 is used in the PROtroniC BaseLINE. Similar to the TopLINE variant, state-of-the-art FPGA technology is used to assist the microcontroller in computing-intensive peripheral tasks and to ensure the required flexibility for the inputs and outputs.

A seamless development environment - from design to production

In order to simplify the everyday work with the PROtroniC, its development environment 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.

The PROtroniC ECU has been a vital tool in many of MAHLE Powertrain's recent advanced engineering projects. Its power, flexibility and ease-of-reconfiguration has allowed us to quickly provide control solutions that would have been difficult or impossible with other systems
