Torque Vectoring Implementation for Formula Student Monopost
Šimanský, Sebastian ; Veselý, Libor (referee) ; Václavek, Pavel (advisor)
This work deals with the design and implementation of an algorithm for adaptive torque vectoring, which is specifically designed to enhance vehicle dynamics and stability. This algorithm manipulates the torques of each wheel based on the vehicle’s angular velocity, allowing for optimization of traction and improvement in agility and control. By utilizing adaptive control strategies, the algorithm automatically adjusts to changing conditions and vehicle characteristics, ensuring efficient torque distribution in various driving situations. The functionality of the algorithm is further demonstrated through simulations, and the required algorithm model is implemented on the main control unit of a Formula Student race car via automatic code generation. The final outcome includes testing on a physical race car and evaluating the algorithm’s contribution to vehicle dynamics.

Logging of vehicle's position by a differential GPS with base station
Vala, Matěj ; Repka, Martin (referee) ; Straka, Tomáš (advisor)
The present work deals with the study of GPS, differential GPS and GPS with base station. The research focuses on the functioning, present status and future development of these systems. Further the thesis presents the actual measurement of the vehicle route using different GPS system. Base station, experimental vehicle, ADMA-G-PRO+, RT3000 and conventional GPS devices were used for the route measurement. The measurements were performed with and without correction. The analysis of the measured data was carried out in Matlab software in TeleMatrix, focusing on different parameters for each GPS system. The first analysis evaluates the route measurements using three GPS systems (RT3000, ADMA-G-PRO+ and a conventional GPS device). The results obtained show the effect of signal quality, horizontal speed, number of satellites, vehicle orientation, heading standard deviation and accuracy status during normal driving and during specific runs for the different GPS systems. The second analysis evaluates the RT3000 with and without correction for different manoeuvres. The evaluated results show that the RT3000 with correction provides higher accuracy than the RT3000 without correction. The RT3000 with correction shows a lower standard deviation of heading in the range of 0.210° - 2.228°, confirming its higher accuracy compared to the RT3000 without correction, where the standard deviation of heading ranges from 0.384° - 4.418°.

Experimental methodology of measuring
Lojková, Lea ; Hejtmánek, Petr (referee) ; Havlíková, Marie (advisor)
This work is focused on the development of a thorough study about ISO standards focused on the vehicle dynamics, standardized tests of vehicle dynamics and measured variables that allow us to describe and model the behaviour of riding vehicles properly. In the Appendix A of the thesis, there is a list of all known ISO standards dealing with given topic. The standard ISO 15037-1 Road vehicles – Vehicle dynamics test methods, Part 1: General conditions for passenger cars is described in detail, including the forms for test reports and the Appendix C and D. In the thesis, there is also described a model of minimal needed measuring system that is still in good accordance with the standard ISO 15037-1 and fulfills all its requirements. Detailed description of all used sensors that are used to measure required variables is given, as well as a short description of all sensors that are used for measurement of other variables. After that, measurement abilities of the instrumentation of measuring system RIO used in ÚADI FSI Brno is compared and confronted with requirements given by the standard, to see, if all given criteria are properly fulfilled. Because of the fact that standard-given criteria are quite mild, while the equipment of the faculty is high-level technology, mostly made directly for measuring of dynamic parameters of the vehicles, including racing vehicles, the system is in full accordance with the standard ISO 15037-1.

Analytical Methods in Motorsport
Růžička, Bronislav ; Dočkal, Aleš (referee) ; Čejka, Václav (referee) ; Karpíšek, Zdeněk (referee) ; Mazůrek, Ivan (advisor)
This dissertation is focused on proposal for simplified data analyze approach for sport-car vehicle dynamic evaluation with relationship to possibility for qualified estimation of set-up parameters influence for overall vehicle performance. In common practice can be usual overlapping effect caused by concurrent changes of car setup elements if performed in the same moment with resulting in not correct or hardly definable process determination for evaluation and decision about next steps in car development. For analyze of these multidimensional data is then chosen process with approach by Linear Regression Model (LRM). In dissertation is proposed basic philosophy with concern on specificity of car vehicle dynamics, performed experiment with defined inputs including analyze and interpretation method of obtained outputs. This methodic take into account also possibility for general application of multidimensional data analyses not only in motorsport, but as well for dynamic behavior diagnostics of technical systems where finding of optimal running condition depends on multi-parametric setup whose combination must reflect often changes of outer conditions too.

Time minimization for vehicles passing a given trajectory
Suja, Jerguš ; Mauder, Tomáš (referee) ; Porteš, Petr (advisor)
The diploma thesis deals with vehicle movement dynamics and defining a theoretical model for software simulation of vehicle passing a given trajectory, while main aim is time minimization driving mode. Simulation (algorithm for computing speed profile) is then applicated for passing experimental vehicle along Masaryk circuit in Brno. At the end, we optimize chosen vehicle parameters with derivate-free algorithms Multilevel Coordinate Search and Particle Swarm.

Influence of Vehicle Conception on Vehicle Dynamics
Hamada, Filip ; Belák, Michal (referee) ; Bilík, Martin (advisor)
Diploma thesis speaks about the influence of vehicle conception on vehicle dynamics, which means how a vehicle behaves in certain typical situations with respect to its driving axle. The first part of this diploma thesis describes the historical background of vehicles, as well as their conceptions and evolutions, with special focus on the conceptions used in the practical element of this work. The second part of this thesis covers the theoretical knowledge of vehicle dynamics and is arranged in a systematic order corresponding to the third section of this work. The third and final chapter then investigates various vehicle conceptions and their dynamics, by running several tests and measurements, in order to make a comparison. This comparison is the main purpose of this work, and from this we can then elucidate which conception, in a certain aspect, is practically more appropriate.

Tyres and Vehicle Dynamics
Kusyn, Petr ; Porteš, Petr (referee) ; Molliková, Eva (advisor)
Objective of this bachelor thesis is mainly the familiarization with factors, that affect vehicle dynamics and the explanation how are these factors reflected in the requirement on the construction of tyres. Another parts are dedicated to the construction itself and properties of the tyre and also to the tyre models, which become essential part in the development of new constructions and materials during manufacturing of the tyres.
