In recent years, due to emission reduction policies, research focused on alternative powertrains among which electric vehicles powered by fuel cells are becoming an attractive solution. Especially, proton-exchange fuel cell has more and more applications in hybrid vehicle. The main issues of these vehicles are the energy management system and the utilization rate of the fuel. In order to optimize...
The problem of vibration caused by frequent engine start-stop which improves fuel consumption is serious in hybrid electric vehicle (HEV). In the new HEV power train-electrical variable transmission, which based on dual mechanical port machine (DMPM), this problem is also severe. In this paper, a control method has been proposed to reduce vibration in the process of engine start-stop. This vibration...
The dual motor powertrain (DMP) configuration is composed of gasoline direct injection (GDI) engine, two motors(one motor connects with input shaft of transmission, namely I-motor, another motor connects with output shaft of transmission, namely II-motor), automatic mechanical transmission (AMT), battery package and hybrid control system. The DMP hybrid system has the functions of engine start/stop...
It has become apparent that a shift needs to be made in the USA from traditional vehiclespsila dependency on petroleum-based fuels to a more diversified source of fuels. Government, universities, and private sectors have begun to see the importance of fuel efficiency, fuel consumption, environmental factors, and health concerns to the population. The importance of these issues has begun to necessitate...
