Impact of the Instantaneous Weight of Vehicles on their Stopping Distance
Motl, Jakub ; Ptáček,, Petr (referee) ; Vémola, Aleš (advisor)
This diploma thesis is engaged in analysis of braking process of vehicles, especially heavy utility vehicles, with regard to their instantaneous weight. This thesis features survey and division of braking systems and function of brakes including schemes and descriptions. Also there is introduce of some systems improving vehicle properties. Furthermore this work puts mind to possibilities of examination of brakes, measurement of braking distance and braking retardation namely in brake test rooms or by outdoor driving tests including descriptions of particular methods and equipment. There is also mention about legislative requirements for braking distance and braking retardation. The conclusion of this thesis compares numerically predicted braking distance and real braking distance measured for factual vehicle during outdoor driving test

Brake Pedal Design
Oravec, Peter ; Janoušek, Michal (referee) ; Ramík, Pavel (advisor)
This bachelor thesis is focused on brake pedal design of Formula Student vehicle. The first part of thesis is focused on main parts of car’s brake systems. Main goal of thesis is to determine value of pedal ratio to gain optimal operating force acting on pedal. Low weight and functionality of the pedal were important factors affecting the research. The design of pedal arm and its holder was checked by final element method and was redesigned according to results.

Train electric traction units brakes control system
Koukolíčková, Lucie ; Vojáček, Zdeněk (referee) ; Němec, Zdeněk (advisor)
Bachelor thesis is focused on improving main operating system of the electric traction units. The main theme is stronger safety for the unit during the ride and keeping the unit movable if there is some problem with the brakes. First par of the thesis is focused on electric traction units and their brake systems. Second part is most about the new screen implementation. This screen shows, if there is some problem with the brakes and the most important part is the speed controller. It is the instrument for the safety arrival of the unit with some brake damage.

Formula Student Braking System Design
Štylárek, Milan ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
Objective of this thesis is design of brake system of new car Formula Student class – Dragon 3. This car was built by students of faculty of mechanical engineering on Brno university of technology. Brake parts selection is described as well as designing hydraulic brake line circuits optimized for stable braking behavior on tracks of Formula Student competitions. One of main parts of this thesis is design of front and rear custom brake discs with related parts. These parts are FEM analyzed. In the end the whole brake system fitted on Dragon 3 car is tested on track and its performance is analyzed too.

Vehicles for driving schools
Rajnštajn, Jakub ; Rekem, Jakub (referee) ; Otipka, Václav (advisor)
This bachelor’s thesis is focused on a description of car adaptations made for driving school needs and the suggestion of another possible upgrades. In the first part, there is described the evolution of common automobiles, especially in spheres important for mentioned potential upgrades. That means the pedal system and active safety technologies above all. Then, there is made a summary of nowadays adaptations, which allow the instructor to control the vehicle during the driving lesson, especially the second pedal controls. Thereafter, there are suggestions of upgrades, which could come with increasing the safety level of the driving lessons. It means especially the possibility to release the brake force from the instructor’s seat, the evolution of additional function of infotainment system and the usage of assistance systems.

Conversion of Vehicle Brake System
Zavadil, Martin ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This diploma thesis is focused on conversion of Skoda Octavia RS mark I brake system. This vehicle will be used for race use. The aim of the thesis is to design adequate components of the brake system to achieve good brake deceleration and so that the design will be correspond to hard conditions on the race track. Thesis contains complete design of hydraulic system including control and brake forces, pressures, options of brake forces management and evaluate of brake stability. Followed by the design of brake caliper adapters and the static structural analysis by FEM. The thesis contains picture and assembly drawing attachment too.
