Series Hybrid Eletric Bus Control Strategy Simulation And Optimization

In order to guarantee the sustainable development of society, people should urgentlysolve the problem of increasingly serious environmental pollution and resources shortage. Theelectric vehicle not only can reduce the consumption of energy, but also can effectively solvethe problem of air pollution, has been recognized by the automotive industry is the mostimportant direction for future development. In general, electric vehicles including pureelectric vehicles, hybrid vehicles and fuel cell electric vehicles. Among them, the pure batteryelectric vehicles because the existing driving range is shorter, higher costs and other issues,fuel cell vehicles because of the high cost of fuel cell technology has not been a breakthroughproblems and therefore the formation of large quantities into the market will also require arelatively long period of time. Therefore, hybrid cars have lower emissions and its good fueleconomy, as the current most popular car electric vehicle industrialization and marketizationhas prospects.Base on comprehensive analysis of SHEV, PHEV and SPHEV, combination with ourcountry city road condition characteristics, finally determines the HEV city bus to use theseries hybrid structure, and analyze the SHEV control strategy characteristics. First, developthe corresponding momentum indicators, a detailed description of SHEV principles andmethods of parameter matching, identifying improvements based on the traditional model ofXiamen Golden Dragon Bus XM6105travel on. Secondly, considering the performance of theoriginal model, Xiamen Golden Dragon Bus travel XM6105HEV powertrain components ofthe selection, parameter matching power XM6105HEV complete drive system. Then adetailed description of the file structure ADVISOR well ADVISOR input interface, set theinterface and output interface, and hybrid city bus powertrain and vehicle key components formodeling. Finally, the simulation results are analyzed and the power of the thermostat controlstrategy to follow two parameters, the parameters of the control strategy is improved. Bycomparing the simulation results, the power and economy performances of the electric citybus have reached the design requirements, and the performance of the HEV is satisfield.
