Abstract
Powertrain structure is introduced first; some important parameters of the power train are matched, according to the vehicle parameters and the driving requirements. The constraints of the transmission ratios are built up following the selecting of the motor parameters. For the purpose of the transmission ratios optimization, the transmission model and the whole vehicle dynamic mode is established on the software platform of MATLAB/Simulink. The optimal transmission ratios are identified by employing the multi-objective optimization genetic algorithm NSGA-II in the software ISIGHT, and the optimal transmission ratios are 7.34i1 13.9 and 5.44i2 8.49 .The optimum , .when it be taken as , , and the ratio of the main deceleration ratio is transmission ratio of the transmission system ig1 = 3.09 ig2 =1.83 i1 =11.75 i2 =6.98 iF =3.8 ig1 = 3.09 ig2 =1.83
