Driving cycles are series of data points that represent vehicle speed versus time sequenced profile developed for specific road, route, city or certain location. It is widely utilized in the application manufacturers, environmentalists and traffic engineers. Since vehicles one higher air pollution sources, driving cycle needed to evaluate fuel consumption exhaust emissions. The main objectives ...

three types of vehicles, pride, peugeot 405 glx and paykan were tested from the point of view of exhaust emissions (co, hc, nox) and fuel consumption, on chassis dynamometer running european standard driving cycle with three kinds of fuels, mtbe free unleaded regular gasoline (urg) as base fuel and 10 and 15 volume percent mtbe –gasoline blends as comparable fuels. utilizing mtbe blended fuels ...

The recognition and prediction of driving pattern is a prerequisite to minimize fuel consumption for plug-in hybrid electric buses with online adaptive energy management strategies. In this work, we present a methodology to develop a driving pattern prediction model from state-of-the-art technologies of cluster, evaluation, and Markov prediction based on the real-world driving speed-time data o...

the primary objective of this work is to introduce a gear ratio selection strategy for a CVT equipped vehicle and show its effectiveness on the fuel consumption reduction. AFuzzy control algorithm is designed for this purpose. Anonlinear model is developed for simulating the longitudinal vehicle dynamics with accelerator pedal applied by the driver as an input. In order that pedal input valu...

The transport sector in Greece has the largest share in the final energy consumption and the resulting emissions are one of the main sources of atmospheric pollution. This situation is worse in the region of Attica, where nearly half of the country’s private cars circulate in an area equal to 3 % of the total country area; the region’s climatic and geomorphological characteristics further aggra...

The vehicle driving cycles affect the performance of a hybrid vehicle control strategy, as a result, the overall performance of the vehicle, such as fuel consumption and emission. By identifying the driving cycles of a vehicle, the control system is able to dynamically change the control strategy (or parameters) to the best one to adapt to the changes of vehicle driving patterns. This paper stu...
