Comparison of Hybrid Powertrain Topologies in Daily Commuting Regime
Ušiak, Michal ; Štětina, Josef (referee) ; Vondrák, Adam (advisor)
The master’s thesis deals with modelling of various architectures of hybrid powertrains for three vehicle sizes in GT-SUITE and compares them in daily commuting operating mode. On top of making of the hybrid vehicle simulation models, control algorithms had to be created to manage the energy split between the internal combustion engine and the electric motor for each of the architectures. Routes to work and back were logged using the GPS and postprocessed to obtain the speed and the road grade profiles. Resulting data was used as an input in simulations of daily commuting. To compare all hybrid powertrain architectures, fuel economy and electricity consumption were evaluated for WLTP and daily commuting operating modes. Finally, the environmental impact of each topology was assessed based on an estimation of corresponding well-to-wheel emissions.

Transmissions of Passenger Cars with Hybrid Drive
Vaňourek, Jakub ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This thesis deals with transmission systems of passenger cars with a hybrid drive. The main reason for choosing this topic was its topicality. With increasingly strict emission standards, hybrid cars are coming to the fore. The first part of the thesis deals with the division of hybrid drives into individual categories according to the selected criteria. An example of a specific solution is then given for the individual categories and its construction, functionality and its advantages and disadvantages compared to cars with an internal combustion engine are described. In the following chapters, more complex hybrid systems are described in more detail in connection with construction and functionality. The conclusion is dedicated to evaluating the mentioned hybrid systems and outlining their potential use in the future.
