Opis:
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.

Opis:
Solution of the propulsion system of the unmanned vehicle elaborated and built in the Laboratory of Internal Combustion Engines Military University of Technology is shown in the paper. Unmanned vehicles are about to play key role in modern warfare. There are many types of unmanned vehicles. Those which can operate in urban areas, especially inside buildings are considered as a most useful for modern army. Most unmanned vehicles are battery operated, causing low range or low speed of the vehicle. Internal combustion engines are not proper for operation inside buildings, due to exhaust gases produced by engine. Connecting two types of propulsion system, defect of range in battery and gases in combustion engines are eliminated, because we can program vehicle to not turning on engine inside buildings. Using a module for those types of vehicles, we can design entire gamut of unmanned and even manned vehicles, decreasing design costs and repair time due to parts repeatability. Using a prepared propulsion module, design engineer can freely determine length, width and wheel track of designed vehicle. Designed modules enable vehicle fast return to combat ability, due to parts repeatability. One module, used as a host, can reconstruct damage vehicle. There is possibility of using different engines, enlarging list of available modules. Economic factor has also big meaning, due to parts repeatability.

Opis:
Investigation scheme of the unmanned vehicle is shown in the paper. It is the unmanned vehicle planned to use in military application. Using the unmanned vehicles on modern war field is increasingly popular. The unmanned vehicle is powered with a hybrid propulsion system. The main source of energy is diesel engine and electric generator. It supplies the battery and six propulsion electric motors. In the propulsion system is a lot of components: controllers and electric devices. Is important to know how it works in load condition. Investigation stand was constructed to break all drive wheels. There will be done measuring of electric parameters of the hybrid propulsion system. Temperature of the battery and electric motors, fuel consumption of internal combustion engine needed to appreciate of load and energy balance will be measured as well. Investigation equipment which will be used during investigation is also performed in the paper.

Opis:
In this article, both problems of the internal combustion-engine’s thermal equilibrium as well as improving the DC-DC converter’s operation in the hybrid-electric vehicle’s propulsion system. The purpose of the proposed amendments is to increase the energy efficiency of the hybrid-electric vehicle’s propulsion system. Such a hybridelectric vehicle in city traffic is characterized by intermittent operation of the internal combustion engine with long pauses, which causes difficulty in obtaining and maintaining the desired operating temperature of the internal combustion engine, especially at low outdoor temperatures and intensive use of the heating system inside the hybridelectric vehicle. The result is the increased emission of noxious exhaust gas components and increased fuel consumption. The proposed solution to this problem is to apply heat accumulator in the cooling system. It is stored in the waste heat from the cooling system used to obtain and maintain the internal combustion engine’s nominal operating temperature. The paper presents the results of simulation analyses the impact of applying heat accumulator in the hybrid-electric vehicle driving in city traffic, at different ambient conditions, such as: air temperature, internal combustion engine’s load and the frequency and length of stops. The proposed algorithm for controlling the circulation of the cooling liquid ensures as soon as possible to achieve and maintain the internal combustion engine’s temperature. Furthermore, the temperature of the operating medium can be adjusted depending on the operating conditions of the internal combustion engine. Experimental studies, on the example of the Toyota Prius and Yaris, confirmed the desirability of the use of the proposed solution. Improving the DC-DC converter’s current is to change the configuration by the use of a two-phase DC-DC converter – instead of a single-phase DC-DC converter, supplying a DC-AC inverter of the DC motoring the hybrid-electric vehicle’s propulsion system. This article also includes waveforms for comparison of the properties of both DC-DC converters.
