Formula Student Braking System
Trna, Lukáš ; Kučera, Pavel (referee) ; Blaťák, Ondřej (advisor)
Describe entire information about design of respective component in Formula (category Student) braking system is object of this thesis. Processing is divided to four main areas. The first one describes basic components in braking system, which goes on analysis of braking system in present used Formula Student Dragon 1. The second one, more spread part, consists of braking system proportioning for Formula Student Dragon 2, respecting pieces of knowledge from first generation Formula. The third part involves design single components of braking system for second generation Formula. This design is supported by measurements and results of calculations. The conclusion of master thesis involves design of caliper model and its FEM analysis.

Simulation model of ABS in passenger car
Svobodová, Jana ; Houfek, Lubomír (referee) ; Grepl, Robert (advisor)
The development of electronics caused revolution the automobile industry. Antilock-Brake-System have become a milestone in the development of electronic security systems. ABS detects susceptibility to locking the wheels, which may occur during braking for critical driving conditions, and then hits. Using of simulation programs is another milestone. Simulation allows repeating of tests and find the best solution of the problem before introduction in practice. Time and development costs are then significantly reduced. In the work is described the most important component of security systems - the braking system and the entire braking process of ABS system. With using a mathematical description of the wheel is in the Matlab-Simulink made quarter model of the vehicle to simulate driving conditions and then created to it a system of ABS. At the end is there an assessment and graphically shown the results of simulations braking.

Electronic stability systems
Musil, Jan ; Ambróz, Richard (referee) ; Zháňal, Lubor (advisor)
In this Bachelor’s thesis there are basic electronic stability systems described. These systems are mostly used as a precaution in safety of the traffic, but also to ensure comfort of the crew. The main part of the thesis is focused on systems ABS, ASR and ESP. The other parts aim to describe additional systems, which are still in development. In the end there is also view of various individual car companies and possible steps in the future.

Design concept six wheel small utility vehicle.
Horák, Šimon ; Píštěk, Václav (referee) ; Rasch, František (advisor)
This thesis deals with a conceptual design of small utility vehicle with three axles. The aim is to devise a suitable type of frame along with construction of all axles and a steering system, implementation of a drive train, a braking system and other basic equipment. Own solution is preceded by elaboration of a survey dealing with small utility vehicles produced nowadays as well as in the past together with a description of all variants of basic assemblies suitable for the construction of the specified vehicle.

Modelling and Analysis of Impacts of ABS to Behavior of Vehicle
Holec, Dominik ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
Bachelor thesis discusses the ABS braking system and its influence on the braking distance of the vehicle. The thesis includes design, description of the development and testing of the model in the UPPAAL verification environment. The resulting model is a system of intercommunicating timed automata. The analysis of the model properties is based on the method of statistical verification. The model allows us to investigate in particular the course and the length of the braking track. Other variables affecting the behavior of the model that can be tracked are skidding, friction coefficient, air resistance, braking force and vehicle speed. It is also possible to obtain the probability of the vehicle stopping within a certain distance under the chosen conditions and examine the impact of ABS on these results.

ABS Impact to Behavior of Vehicle
Zich, Jakub ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The bachelor thesis discusses the Anti-lock braking system and its impact on braking distance of a vehicle. The thesis contains research of this problem, a summary of suitable modeling tools, solution draft, its implementation in the UPPAAL modeling tool and tests performed with the model. The tests examine the course of progression of basic quantities associated with braking (velocity, braking distance, slip, angular velocity, friction coefficient) in simulations of emergency braking with and without the use of ABS, and compare the results. They also verify probability of the vehicle stopping in different circumstances on given distance. Lastly, the model can simulate brake or sensor defect, and results of those simulations can be compared to simulations without defect.
