First goal of the thesis is to give an overview of the current status of hybrid vehicle development. Elements of hybrid drive systems are examined and the main advantages and disadvantages of different hybrid drive types (parallel, serial and power-split), used machine types and energy storage options are shown (energy storage with batteries or supercapacitor). We give an overview description of the mechanical elements and their effects on drive properties. As conclusion, an exact hybrid drive system is outlined based on the previous results.
Another focus point is the simulation of a switched reluctance motor in Matlab - Simulink. The load on the simulated machine is varied following a real-life application (data is calculated taking the properties of a bus line in Budapest). Using the data from the simulation, electrical and mechanical power is measured at different rotor (vehicle) speed levels and switch angles and efficiency is calculated. This efficiency is then compared with the results of conventional vehicle driving solutions.
