Hybrid Electric

With the requirements for reducing emissions and improving fuel economy, it has been recognized that the electric, hybrid electric powered drive train technologies are the most promising solution to the problem of land transportation in the future. In this paper, the parameters of series hybrid electric vehicle (SHEV), including engine-motor, battery and transmission, are calculated and matched. Advisor software is chosen as the simulation platform, and the major four parameters are optimized in orthogonal method. The results show that the optimal method and the parameters can improve the fuel economy greatly.

Line Pressure

An optimal line pressure control algorithm was proposed for the fuel economy improvement of an AT-based parallel hybrid electric vehicle (HEV). By performing lever analysis at each gear step, the required line pressure was obtained considering the torque ratio of the friction elements. In addition, the required line pressure of the mode clutch was calculated. Based on these results, the optimal line pressure map at each gear step of the EV and HEV modes was presented. Using the line pressure map, an optimal line pressure was performed for the AT input torque and mode. To investigate the proposed line pressure control algorithm, a HEV performance simulator was developed based on the powertrain model of the target HEV, and fuel economy improvement was evaluated. Simulation results showed that as the gear step became higher, the optimal line pressure control could reduce the hydraulic power loss, which gave a 2.2% fuel economy improvement compared to the existing line pressure control for the FTP-72 mode.

Fuel Consumption And Emissions

Recently, due to the reduction of oil and the deterioration of environment, people raised higher request for fuel economy and emissions, hybrid vehicle developed rapidly in most countries because of its low fuel consumption and emissions. In order to develop appropriate hybrid system, the text builds the model of prototype bus in the AVL-Cruise platform first, and then, establishes the model of PHB and accomplishes the control strategy of vehicle in the MATLAB/SIMULINK environment. The simulation data indicates: PHB can improve the fuel economy and emission performance effectively with guaranteeing a good dynamic performance of bus.
