Simulation of the hybrid propulsion system for the small unmanned vehicle

The paper presents a simulation model of an unmanned vehicle propulsion system designed and constructed at the Laboratory of Internal Combustion Engines WAT. The vehicle was modelled in the software environment AMESim. It is intended as a tool for modelling of mechatronic systems, and therefore it was possible to create a link between mechanical parameters such as gears, with elements from the fields of electrical engineering and electronics, such as electric motors and inverters. Presented undercarriage system modelled the platform with 6x6 and independent drive wheels. Presented model of the hybrid structure of a small unmanned vehicle and sub models driver module and the propulsion module battery charging electric current through a combustion engine (generator controls, the switching of electric current battery capacity following a drop below the desired value - for this calculation was 50% of battery capacity). Characteristics of parameters changes of sets are presented. Simulation study for two batteries of different capacities as an example of the synthetic driving test and analyzed the differences between the foundation and set of characteristics. It was found that the higher-capacity battery could provide a better change of speed.
