This paper proposes a control approach for the energy management of parallel hybrid electric vehicles based on stochastic model predictive control (SMPC). Apart from minimizing fuel consumption, the controller additionally accounts for CO2 emissions. Considering the vehicle’s velocity to be time-varying, the limits for both propulsion machines of the hybrid vehicle are determined over a multipl...

performances of electronic and mechanical draft control systems on a mf399 tractor were the objectives of the study to be evaluated and compared under field conditions. hence, the effects of two draft control systems (mechanical and electronic) under four ground speed levels and three set values of draft levels on rear wheel slippage, fuel consumption, compressive force within the top link and ...

* Corresponding author. ABSTRACT Designing vehicles specifically for city use is a topic of increasing interest in the transportation community. Hybrid vehicle design typically seeks to maximize fuel economy subject to acceleration performance and other constraints, based upon the expected driving needs of the average user. Fuel economy predictions are inaccurate when the vehicle’s expected and...

as motorcycles are named as one of the important air pollution emission sources in tehran, investigating their emission performance and finding a solution for reducing their emission is of high importance. in this study, emission factors from 60 motorcycles from tehran’s present fleet and 4 closed loop injection fuel supply system and catalytic converter equipped motorcycles were measured. meas...

Design and optimization of automotive engines present unique challenges on account of the large design space and conflicting constraints. A notable example of such a problem is optimizing the fuel consumption and reducing emissions over the drive cycle of an automotive engine. There are over twenty design variables (including operating conditions and geometry) for the abovementioned problem. Co...

Due to the necessity of using highly efficient power generation systems to reduce fuel consumption and air pollution, the integration of different energy systems is promising modification to achieve higher efficiency. In this paper, the integration of an Internal Reforming Solid Oxide Fuel Cell (IRSOFC)-Gas Turbine (GT)-Organic Rankine Cycle (ORC) system has been proposed. In this regard, therm...

In this paper a multi-variable LPV/H∞ control approach is applied to design a strategy for power source coordination within a multi-source energy system. Three different kinds of power sources – fuel cell, battery and ultracapacitor – compose the power supply system of an electric vehicle. All sources are current-controlled and paralleled together with their associated DC-DC converters on a com...

The difference in the dynamics of development motorization regions world, levels traffic organization, determines need to develop a methodology for specific operating conditions. Improvement existing driving cycles and methods their development, which characterize real conditions, is great importance. An important task considered implementation targeted research improve automobile operation eff...

Motivating car drivers to change their habitual driving behavior toward a less fuel consuming way is an ambitious task. In this paper a game like approach based on the concept of location based challenges will be presented in order to allow drivers to compare their fuel efficiency with other drivers of the same route section in real-time. A mobile device display was used to provide feedback on ...

The transient behavior of a Fuel Processor System to produce Hydrogen from bio-ethanol with high performance, coupled with a Proton Exchange Membrane Fuel Cell is modeled. The Ethanol Processor is based on a previous steady state design, optimized to work with maximum efficiency around 10 kW of rated power. From the dynamic rigorous model, a linearized model is identified to apply a systematic ...
