Virtual Drivetrain
Thanks to years of involvement in simulation technology, FKFS has gathered extensive experience in the field of drivetrain simulation. This has also resulted in the creation of a comprehensive, modular drivetrain simulation library, which can be used to rapidly model diverse drivetrain topologies with variable modeling depths, in order to answer all kinds of questions.
Our component models are easily scalable and parameterizable, so we can generate drivetrain models for your particular question very quickly. We are also able to model specific vehicles. Coupling with in-house driving dynamics simulations or with IPG Carmaker is also no problem.
Typical applications:
- Comparing variants
- Application-related component dimensioning
- (Pre-)application
Advantages of simulation compared with road testing:
- Reproducible situations
- Can conduct investigations before components are available
Drivetrain Simulation
Drivetrain Simulation
In recent years, FKFS has implemented an extensive model library for simulating diverse drivetrain topologies using the simulation tool Matlab/Simulink. This enables us to rapidly define and parameterize all kinds of hybrid drivetrain structures, conventionally-powered drivetrains, electric drivetrains in many variants, 4x2 or 4x4.
The modeling depths of the available component models are scalable so that, depending on the application, it is possible to investigate dynamic phenomena at extremely high resolutions as well as answering unspecific questions. This enables simulative investigations to be carried out very quickly on specific drivetrains. FKFS has years of experience in drivetrain simulation, gathered from a wide range of projects.

Application-related Component Dimensioning
Application-related Component Dimensioning
Thanks to our drivetrain model library, we can model specific drivetrain topologies very quickly. If an application is defined by a load profile, multidimensional parameter variation can be used to optimize the dimensions of various components. This enables optimum component designs with regard to wear, efficiency and cost to be found for defined application cases.
RapidCylinder®
RapidCylinder®
Conducting a reliable powertrain simulation with RDE (Real Driving Emissions) often represents a special challenge. Firstly, due to the increase in calculation time because of the numerous driving profiles to be tested, and secondly due to the need for high-quality results – necessitating resolution of the gas path. The dilemma: increasing the simulation speed in the gas path has a negative effect on the quality of the results regarding the combustion process and raw emissions. But these play an important role in reliable evaluation of the RDE.
To solve this problem, we have developed RapidCylinder® as a plug-in for the GT-Power flow simulation. The fundamental idea: as previously, the gas path is modeled physically and can depict all the relevant effects. However, at the same time, the calculation time can be drastically reduced thanks to data-based modeling of the high-pressure component in RapidCylinder®. This enables extremely accurate and reliable results. RapidCylinder® offers you a rapid, flexible, precise and therefore powerful tool for evaluating RDE for powertrains.

Concept Evaluation
Concept Evaluation
The initial RDE evaluation for powertrain concepts should be conducted as early on in the development process as possible. This is particularly important for hybrid powertrains. However, at this point, stationary measurement data from the engine test bench is generally not available. In this case, you can combine RapidCylinder® with our UserCylinder®, which enables you to simulate the combustion process as well.
Especially for high-efficiency concepts, switching off the combustion engine may result in the exhaust aftertreatment system cooling down. The advantage of hybridization may then be significantly reduced due to the heating requirement for exhaust aftertreatment. This should be taken into consideration early on in the design phase.
In addition to the sale of licenses for our development tools and the associated product support, we also offer a range of services.
Since – to achieve reliable results – the assessment of different powertrain concepts in particular requires a great deal of experience right from the start, we are happy to provide you with support in conducting concept studies at any time.
