Reducing fuel consumption, lowering emissions and improving driveability represent the main interests nowadays in automotive research centres from both academic and industry fields. The purpose is to develop more complex and accurate models for the automotive drivetrain in order to design and to apply different control strategies. In this paper, starting from the relations that describe the dynamical...
50 “zero emission” pure electrical buses BK6122EV have been running in Beijing for the whole year. As one of the core systems of the bus, the automatic mechanical transmission (AMT) has the enormous influence on its economical performance. In order to further optimize the economic gear-shifting schedule for BK6122EV, this paper uses three design methods of the conventional engine vehicle for reference,...
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 main objective of vehicle powertrain hybridization is to simultaneously improve the fuel consumption and environment pollutants impact (Eco-score) without decreasing the vehicle performances and other user satisfaction criteria. Based on a simulation model in ADVISOR, one can evaluate the performances, the emissions and then the Ecoscore and the user satisfaction for different driving scenarios...
The powertrain dynamic simulation model of an integrated starter/generator (ISG) hybrid electric vehicle (HEV) was established. Based on it, the parallel electric assist control strategy (PEACS) was analyzed and designed. The analysis of dynamics performance and fuel economy of the model was carried out under the FTP drive cycle, which can provide a design reference for the setup of the powertrain...
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...
Because of lower fuel consumption and emissions, especially unlimited drive mileage, hybrid electric vehicle (HEV) has long term potential for future main stream vehicle. Based on conventional vehicle CHERY A5, this paper analyzes the framework of powertrain and control strategy of the parallel hybrid electric vehicle. A method of powertrain parameters matching is presented. On the basis of engineering...
