Power Trains

This research field is also named the Van Doorne Chair, after Dr. Hub van Doorne. He was the founder of DAF and the inventor of the DAF Variomatic; the first automotive application of a Continuously Variable Transmission.

The research field Power Trains is part of the Control Systems Technology Group of Prof. Dr. Ir. Maarten Steinbuch and performs research on Continuously Variable Transmission systems as well as (hybrid) power train components, under supervision of the part-time professor Nort Liebrand.

Coupling at drive-off and shifting, damping of engine vibrations, and transformation of a high engine speed to a low speed at the wheels, are only a few functions the power train of a vehicle has to perform. The design of a power train is mainly responsible for the performance, fuel consumption and emissions of a passenger car.

 


Because of the constantly changing demands of customers and governments, and the development of new technologies, numerous automotive engineers are performing research on the improvement of power trains. Some recent developments are: Hybrid vehicles, Continuously Variable Transmissions (CVT) and Automated Manual Transmissions (AMT).

If you would like to graduate in the research field of Power Trains, you will be part of in-depth research concerning CVT-technology, CVT-equipped power trains, hybrid vehicles and automated manual transmissions. Master's projects can be performed at an automotive company or at the university.

Research in the field of power trains is divided in two streams:

Component Research
This research stream focuses on the application of the latest technologies and methods to characterize power train subsystems and subsequently improve these systems.

Students who perform component research are mainly concerned with the making and testing of innovative designs, the development of motion control systems and application of these technologies within prototype vehicles.

System Research
The results of the component research stream have to be implemented and validated by application in such a way that the vehicle is functioning optimally.

Knowledge of interaction between the several subsystems, the driver and influences from the surroundings is required to come to an optimal performance. Students create new system-layouts and perform simulations. When the design is fulfilling the requirements, a prototype of the power train is built and implemented in a vehicle or test-rig to analyse its performance.
