Master's thesis deals with the field of hybridization of military off-road vehicle drive trains. In the thesis, we present their performance requirements, some concepts of hybrid electric drive assembly generic architectures and basics in the field of regenerative braking. Based on the analysis of the performed accelerating and braking tests of the 8 × 8 Svarun medium wheeled armoured vehicle driving dynamics, we assessed its accelerating and braking performance characteristics. Based on continuous measurements, we determined five characteristic operating driving cycles and calculated an estimation of the energy needs, as well as an estimation of the theoretically available regenerative braking energy for driving within them. We also performed measurements in order to determine the total running resistance of the vehicle. We combined results of the vehicle operation analysis with theoretical starting points of the performance requirements and estimated suitability of the presented individual hybrid architectures.
