柴油机开启转矩门限值、柴油机开启转速门限值以及气动发动机占总输出功率的转矩分配比是影响采用逻辑门限值控制策略的并联型气动柴油混合动力汽车性能的关键参数。以这三个关键参数为设计变量、以整车油耗量、气耗量以及原地起步加速时间为目标函数，采用正交优化设计方法研究了这三个参数对整车动力性和经济性的影响。研究结果表明：柴油机开启的转矩门限值、开启转速门限值以及转矩分配比的提高，能有效的降低柴油的消耗，但会引起压缩空气的消耗量的增加以及整车的动力性能的降低。

The threshold values of torque and speed for the diesel engine entering into working state and the torque assign ratio for air powered engine ( APE) are the key parameters to the parallel hybrid air-diesel vehicle ( PHAV) using logical threshold control strategy. The method of orthogonal optimization is used to study the effect of these key parameters on the diesel con-sumption, air consumption and in situ acceleration time for PHAV. The results show that the increase of the threshold values of torque and speed for the diesel engine entering into working state and the torque assign ratio for air powered engine ( APE) would effectively reduce the diesel consumption, however, it could increase the air consumption and degrade the dynamic per-formance of PHAV.
