Influence of Tyre Defect on the Driving Dynamics of a Vehicle
Kubík, Adam ; Bradáč, Albert (referee) ; Panáček, Vladimír (advisor)
In this thesis, an effect of a tyre defect on the driving dynamics of a vehicle is dealt with. The first part of the thesis is mainly concerned with the vehicle dynamics, road resistance, adhesion, orientation characteristics of the tyres and slowing down. This chapter is followed by an overview of the manufacturing process and construction of modern passenger car tyres. The practical part is focused on driving tests that are used to demonstrate the influence of tyre defects on handling characteristics of the vehicle. The main focus of this thesis is on directional variation, braking distance, deceleration and lateral acceleration. The very end of the thesis concentrates on tyre defect in higher speeds and its after-effects as well as precautions for mitigation of these after-effects.

Road Resistances of Vehicles
Prachař, Roman ; Dadák, Leo (referee) ; Rochla, Tomáš (advisor)
his thesis deals with the analysis of particular road resistances that affect the car. It describes their importance and factors that influence their size. This thesis defines steps that determine particular quantities that are necessary to assess road resistances. Describing, it qualifies transfer and sizes of driving force that is needed to overcome total road resistance, measuring methods of road range tests upon appropriation of road resistances and influence of road resistances on economy of traffic. Practical part discusses the plan and course of realized measuring of selected sample of cars. Final part deals with the evaluation of measured values of realized measuring.
