Study of torque vectoring clutch design
Cupák, Václav ; Porteš, Petr (referee) ; Fojtášek, Jan (advisor)
This work deals with the design of right and left torque vectoring control used in heavy commercial vehicle powertrains. The beginning of the work is focused on the description of the active differential system and on the clutches used in the automotive industry. Then the basic parameters of the experimental vehicle are defined and the choice of the clutch conception is made. Subsequently, calculations of geometric parameters of clutches and verification of their heat capacity is made. Conceptual design of the control mechanism is discussed in the last chapter. The aim of the work is the draft of the possible type of control mechanism for the given system with the possibility to use the information obtained for the further development of this system.

Torque vectoring differential utilization in the design of the current automobiles
Marek, Martin ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
The object of this bachelor thesis is to create analysis of the structural design ”Torque Vectoring” differentials and powertrain vehicles which use this type of differential. The project outset is devoted to an explanation of what the differential is and how it works, and then the distribution of differentials. The next section deals with active differentials, their principle function and design solutions. The end of thesis includes design solutions powertrain some models of vehicles using active differentials. The thesis has the character of search and contains no calculations or custom designs.

Torque Vectoring Differentials for Heavy Commercial Vehicles
Fojtášek, Jan ; Magdolen,, Ľuboš (referee) ; Tůma, Jiří (referee) ; Porteš, Petr (advisor)
This work deals with the assessment of the yaw moment control via active differential effects to the heavy commercial vehicle dynamics. Summarized are the findings about design of active differential, control algorithms and theoretical assumptions about overall effects to the vehicle dynamics. According to the described theory the own concept of the active differential for experimental heavy commercial vehicle is proposed. The main part of the work is focused on the effects of the active differential on vehicle manoeuvrability, controllability, stability and limits analysis. For this purpose, multibody dynamic model of the complete vehicle with standard open differential is assembled and results of the selected manoeuvre simulations validated by measurements of the real vehicle characteristics. The validated vehicle model is then extended by the model of the active differential with control algorithm. According to the simulations results the theoretical presumptions are confirmed and the effects of the active differential on vehicle dynamics in steady and transition states are evaluated. Based on the described findings the overall improvement of the vehicle dynamics by this technology, feasibility of the proposed concept and main advantages and disadvantages are evaluated.

Study of torque vectoring differential use for heavy commercial vehicles
Fojtášek, Jan ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
This work deals with the design of right-and-left torque vectoring systems used in heavy commercial vehicle powertrains. It is a new device for a commonly used vehicle differential. This study recommends design, kinematic and load parameters. Also the overall effect of the mechanism on vehicle dynamics and design of the experimental vehicle chassis is described. The study further describes how the mechatronic system works with necessary control systems. Purpose of this thesis is to summarize available information on a right-and-left torque vectoring and possible practical applications for further development of torque vectoring systems.
