Mechatronic systems support the driver and provide feedback about the current vehicle dynamics in modern vehicles. Our company is successful in the development auf such mechatronic systems since more than a decade.

Steering Systems

Our controls for electro-mechanical and -hydraulic steering systems meet highest requirements on driving safety and steering feel. By this we had serious impact on the development of electrical steering systems by using optimal controllers. These were tested in experiments successfully and are deployed in serial products. We program new tools for the design of modern steering systems. With these it is possible to design the shape of orifices of steering valves optimally or to determine optimal values for gear ratios or inertias for superposition steering systems. With our own hardware-in-the-loop systems we test EPS-actuators and new algorithms for steering feel.

Braking Systems

For fast and comfortable dimensioning of electro-mechanical and –hydraulic braking systems we develop models and customer specific tools. we achieve Optimal system behavior by developing innovative control algorithms. For example allows our controller for an electro-mechanical brake booster to deliver a brake force requested by the driver, the brake assistant or a vehicle dynamics controller, with high dynamics and precision.


For the setup of application specific drivetrain models we have an own library featuring models for components like dry or wet clutches, torque converter, differential gears and different actuators. For drivetrain systems we have developed and implemented controllers for throttle valves, cam shaft actuating, and automated clutches and have developed systems for optimal torque transmission.
For modern electrical vehicles we have developed models and software for energy management (recuperation).

Vehicle Simulation


Reliable vehicle models are essential for development and test of vehicle systems. We have developed our own environment for the real-time simulation of vehicles. The open and modular model structure allows to setup an application specific model with exchangeable component models for body, suspension, tires, engine, drivetrain, braking and steering system, road and driver. We use these models for the development of vehicle dynamic controllers and observers as well as for testing components in hardware-in-the-loop (HiL) simulation.
Commercial vehicle models like dSPACE ASM are familiar to us from several projects.


The electrification of the drivetrain creates new challenges in the development of vehicles. ECUs and control algorithms are getting more complex, the energy efficiency needs to be optimized and the connection to the power grid needs to be considered. In established development processes time and money consuming system analysis with test benches and prototypes gets necessary. By developing a suitable environment it becomes possible to replace tests and experiments with physical test objects by virtual tests with simulated test objects. This allows testing the design in an early stage of development, to reduce the effort for prototypes and by this to increase cost effectiveness. Therefore, electric-vehicle specific models and controllers have been developed and compounded to a full vehicle dynamics model. In the next step, the controllers have been integrated into an overall AUTOSAR architecture. The simulation results allow analyzing the controller on the functionality and software level as well.
