Effect of Suspension Kinematics on Vehicle Handling
Trnková, Lucie ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This diploma thesis deals with effect of suspension kinematics on vehicle handling. In the first part of the thesis, there are the basic parameters of suspension kinematics introduced. In order to perform the simulations, two multi-body vehicle models are created, one of which is derived from an off-road vehicle, for which there has been a significant change in suspension. For each model, there further is a description and comparison of the kinematic characteristics of different settings variants of their suspension introduced. The main part of the thesis deals with the analysis effect of individual suspension changes on vehicle handling during the selected driving maneuvers. The results of the simulations are qualitatively and quantitatively evaluated, and the resulting findings are in the conclusion summarized.

Optimisation of Race Car Suspension
Gašpar, Dominik ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
The thesis deals with the kinematic characteristics of vehicle suspension and its essential parameters, analysis and optimization for use on ride on unpaved surface. Subsequent analysis of change of kinematics on driving simulations shall verify the modifications made in terms of driving characteristics of the race car

Analysis of vehicles driving maneuvers at low coefficient of adhesion
Šabík, Matúš ; Sedlák, Robert (referee) ; Tokař, Stanislav (advisor)
This master’s thesis deals with driving maneuvers at low coefficient of adhesion, especially in winter season. It includes a list of adhesion coefficients on many surfaces, published by various authors. Figures were through the use of statistical methods divided into normal and exceeding. There are described terms having impact on adhesion. For determination of adhesion was used tests like emergency braking, circle test and slalom. The major part contains specification of used vehicles, surfaces, weather conditions, measuring devices and realized tests. In addition to using accelerometer, there was a successful attempt to use timekeeping facilities to determine deceleration of vehicle. Acquired data were processed and compared to another publications.

Driver Steering Model for Simulation Algorithms
Tmejová, Tereza ; Zháňal, Lubor (referee) ; Hejtmánek, Petr (advisor)
This diploma thesis deals with the creation of a computation driver model. In the first part, there is an overview on driver models for longitudinal and lateral control. Next, driving maneuvres that could be selected for testing of driver model are described. In the practical part, there is created a computational driver model, whose task is to follow required path. The resulting model is tested on three driving maneuvers - steady turning, moose test and slalom. Finally, this model is tested on the passage of a real track. For all these tracks, a comparison is made and the success of the model is evaluated.
