Hybrid Electric Vehicles (HEVs) are driven by two energy convertors, i.e., an Internal Combustion (IC) engine and an electric machine. To make powertrain of HEV as efficient as possible, proper management of the energy elements is essential. This task is completed by HEV controller, which splits power between the IC engine and Electric Motor (EM). In this paper, a Genetic-Fuzzy control strategy...

A good driving cycle is needed for accurate evaluation of a vehicle’s performance in terms of emission and fuel consumption. Driving cycles obtained for certain cities or countries are not usually applicable to other cities or countries. Therefore, considerable research has been conducted on developing driving cycles for certain cities and regions. In this paper, a driving cycle for a taxi in A...

Hybrid Electric Vehicles (HEV) offer the ability to significantly reduce fuel consumptions and emission. Management of energy is one of essential elements in the implementation of HEV. The parameters of HEV control strategy are always optimized on some one standardized driving cycle, but the different city has its own driving cycle. So the great advantage of parallel HEV is limited. This paper ...

Against a kind of parallel hybrid electric bus which is demonstrated in a city of China, a simulation model of the parallel hybrid powertrain system is established by referring to parameters of the demonstrating bus. Regarding the Chinese typical city bus driving cycle and the bus driving cycle of Harbin City, Heilongjiang Province as the driving cycles for the simulation, the fuel economy of t...

In order to transform conventional buses into electric ones, exact knowledge of the energy consumption vehicles is essential. Furthermore, for a proper design transition and avoid inefficiencies excessive costs, this information must be adjusted real operating scenarios. However, recurring problem in context lack data address all these issues. Previous studies have focused on use standard drivi...
