摘　　要：就燃料电池客车混合动力系统提出了一种基于电机功率分段组合优化算法,该方法是以路况为基础统计出电机功率的分布情况,并将分布离散化(分段),然后采用遗传算法进行优化组合,得出给定道路工况下的优化的功率组合分配方案。最后进行了仿真计算,结果表明该算法的可行性。In the paper,one optimization algorithm which is based on piecewise combination of electric motor power is presented for the hybrid power system of a fuel cell bus.The algorithm is to obtain distribution of electric motor power over road conditions with statistical methods,then to make it discrete,and then to get the optimized power combinatorial distribution solution under the given road condition by optimizing and combining with the genetic algorithm.In the end, simulation and calculation are carried out and it is shown by the results that the algorithm is feasible.
