Modelling and Control of Hybrid Vehicle

Environmental pollution is one the major issue for entire world. Burning of petroleum and gas in combustion engines of vehicles is one the biggest sources of harmful environmental pollution. To keep in mind this issue, hybrid technology is evolving as one of the latest way to get rid of this problem but obviously it will take much time to remove almost 70% gasoline engines overall in the world. In this study, same sort of issue is discussed. Improvement of fuel consumption in automobile by increasing the number of gears is explained in this paper with graphs. Parallel hybrid electric vehicle is modelled by using Matlab/simulink for 4th and 6th gear automatic transmission. 4th gear transmission is not much fuel economic due to which number of gears are increased up to 6 to improve the fuel economy of hybrid vehicle. The logic behind the increment of gears is also explained very well. Improvement of fuel consumption and mileage of vehicle is presented by theoretical and also by comparing the graphs by using different drive cycles for 4th and 6th gears automatic transmissions
