The main activities of the team includes vehicle and vehicle sub-system modeling, parameter identification, validation and test measurements and vehicle control. Modeling is a useful and cost effective tool for analyzing, tune and develop vehicle systems and their interaction with the environment or with other sensing or control systems installed in the car. The definition and correct implementation is insufficient for the realistic behavior of numeric models, hence, a special emphasis should be put on the parameter identification and validation
For this purposes, a wide range of measurement equipment is needed. The teams work is supported by various sensors and measurement systems including but not limited to different kinds of dual antenna GNSS systems with RTK correction, a Correvit 2-axis optical sensor, IMU units, strain-gauge measurement system, etc. A direct access to the test platforms of the ZalaZONE Automotive Proving guarantees that a wide variety of test runs can be carried out such as highly dynamic test on the dynamic platform and the handling course as well as on different surface qualities on the braking platform.
The most commonly used platform for custom model implementation is MATLAB/Simulink that ensures quick and flexible model development, evaluation and documentation. Commercial modeling softwares are also available for simulation purposes such as IPG CarMaker, PreScan, VTD Vires. With the coupling between the above simulators and MATLAB/Simulink a suitable customization and improved flexibility can also be achieved. Based on the knowledge regarding vehicle modeling the other main field of the team activity incorporates the function and control software development for automated and regular vehicles. Our activity is focused both on component level (e.g. steering control, brake control, etc.) as well as high level functions (e.g. driver assistance systems and automated driving). Implementation, testing and data acquisition are usually carried out with dSpace AutoBox rapid prototyping units that are available in various types. The teams competency includes the modification of vehicle to enable steer-by-wire which is essential for reproducible testing and the development of self-driving functions. Current the research activities are focused on vehicle motion control at handling limits and vehicle-drone interactions.
