Based on the drive train for series-parallel hybrid electric vehicle that can make more combination between engines, generators, motors and so on,and the system can be ensured to work under the better conditions from the structure. By matching and analyzing on the drive train for series-parallel hybrid electric city bus,it is advanced that matching scheme and control strategy were proposed on drive train for series-parallel hybrid electric city bus,also,a sample bus was developed successfully. By the demonstration, it is indicated that the vehicle performance of drive and economy meets the design demands. The sample vehicle has better result in saving oil and can provide the reference for the scale demonstration.%混联式混合动力系统能够使发动机、发电机、电动机等部件间有更多的组合,并在结构上保证系统能在复杂的工况下工作在最优状态.通过对混联式混合动力城市客车动力系统的匹配和分析,提出了一种混联式动力系统的匹配方案和控制策略并成功开发出样车.示范运行结果表明,整车动力性及经济性满足设计要求,节油效果良好,可为规模化示范运行提供依据.
