Supplying enough power and energy during vehicle operation is one of the key elements in competitive automotive industry. In other words, providing the feeling of smooth operation brings the vehicle a step further when compared to its competitors. So, the main goal behind this research is to examine vehicles with three different powertrain systems and observe their behavior over different drive cycles. Vehicle performances are analyzed under different categories such as consumption (i.e., electricity, fuel), economic perspective, and emission point of view. Since vehicle electrification is a hot topic in Turkey, researchers add a real-life road simulation of Istanbul-Adapazarı Road into perspective alongside regulative drive cycles to try and provide an insight of BEV and HEV behavior, in detail. All three vehicles are modeled on MATLAB/Simulink and the outcomes of simulations are presented in this study.
We describe a laser written, zebra patterned graphene saturable absorber with different ablation duty cycles, which works as a mode-locker with adjustable loss and demonstrate femtosecond pulse generation near 1250 nm with improved power performance.
World Solar Challenge (WSC) is a race held for solar powered vehicles from all around the world in every two years and multiple contestants from Turkey attend to this competition. The aim of this paper is to find a way of increasing the performance of vehicle during the qualifying lap of the race via modelling and dynamically simulating the solar vehicle. For this study, IPG/Carmaker software is used and a solar vehicle formed by two front and 1 rear wheel is modelled. Performance enhancer parameters including the vehicle design is selected and implemented to the model. Additional to vehicle model, race track is also modelled according to its physical features. According to gathered simulation results vehicle velocity and race duration is optimized. Vehicle is also tested on additional test cycles from literature and test outcomes are compared. Moreover, discussion between studies from literature is held.
With decrease in amount of carbon fuels and aims of creating a cleaner environment, researches on hybrid electric vehicle technology have increased in years. The purpose of this study is to observe the change in fuel consumption of a simulated hybrid electric vehicle in different driving cycles. For this research, a series hybrid electric vehicle is modelled on MATLAB/Simulink. Subsequently, for simulating the tour of the vehicle, multiple driving cycles are modelled on the software and fed to vehicle model. For instance FTP-75, NEDC and UDDS are benefited and also a route from Turkey, the road from Istanbul to Ankara is modelled and simulated. Behavior of the vehicle on this route is also observed. After analyzing vehicle behavior in all these cycles, fuel consumption in each case is calculated and compared. As the result of this research, the most affordable cycle for this vehicle model is selected and possible ways of decreasing fuel consumption in other driving cycles is discussed.
