Abstract:This paper presented a two speed automatic transmission (AMT) drive scheme by calculating and matching Powertrain Parameters. Based on iSIGHT and cruise co-simulation platform, the power system was simulated and analyzed. Taking the maximum gradient, maximum speed and transmission speed ratio range as constraints, the multi-objective optimization was carried out with 0-100km / h acceleration time, maximum gradient and 100km power consumption as objectives. The influence of multi Island genetic algorithm, NSGA-II and pointer optimizer algorithm on the results was studied. The results show that the convergence of NSGA-II kkoptimization is more stable and the optimization results are more balanced.
