功率分流式混合动力系统的加速性能分析

Acceleration Performance Analysis of Power-split Hybrid Powertrain System

为满足功率分流式混合动力汽车的加速性能设计要求,使用构型矩阵对双行星排构成的功率分流式混合动力系统进行穷举,并根据构型合理性及设计目标进行筛选。对于各种构型的双行星排功率分流系统,提出了其能够输出最大转矩的系统解法。利用求解结果对各种构型的系统进行百公里加速仿真,得出最优构型。

To fulfill the design goal of acceleration performance of a power-split hybrid vehicle,constraint matrices of all possible configurations of power-split hybrid powertrain system that can be constructed by twoplanetary-gear system are derived and screened.A systematic solution to the maximum output torque of all types of two planetary gear power-split systems is introduced.Base on the solution,the 100 km acceleration performance of the derived configurations are simulated,so that the optimal configuration is found.
