The invention relates to a method for controlling a hybrid drive train (100) having an internal combustion engine (ICE), a crankshaft (KW) and a dual-clutch transmission (DKG) which transmits a drive torque (M (A)) to drive wheels (AR) and which has a first partial transmission (TG1) and a second partial transmission (TG2), the invention relates to a first sub-transmission (1, 3, 5, 7) which can be shifted between a first transmission input shaft (GE1) and a first transmission output shaft (GA1), and a first friction clutch (C1) which is arranged between a crankshaft (KW) and the first transmission input shaft (GE1), the second partial transmission (TG2) has a plurality of gears (2, 4, 6, R) which can be switched between the second transmission input shaft (GE2) and the second transmission output shaft (GA2), a second friction clutch (C2) which is arranged between the crankshaft (KW) and the second transmission input shaft (GE2), and an electric machine (EM) which is associated with the second partial transmission (TG2). In order to be able to reduce the load on the dual clutch (DK) and to be able to design the dual clutch (DK) more simply, the electric machine (EM) takes over at least part of the drive torque from the internal combustion engine (ICE) in a torque-overlapping manner before shifting between the gears of the two partial transmissions (TG1, TG2) and performs a change in the frictional engagement of the friction clutches (C1, C2) when the frictional power is at least reduced.
本发明涉及一种用于控制混动动力总成(100)的方法,所述混动动力总成具有内燃机(ICE)、曲轴(KW)和将驱动扭矩(M(A))传输到驱动轮(AR)上的双离合器变速器(DKG),所述双离合器变速器具有:第一子变速器(TG1)以及第二子变速器(TG2),所述第一子变速器具有多个在第一变速器输入轴(GE1)与第一变速器输出轴(GA1)之间可切换的挡位(1,3,5,7)和在曲轴(KW)与第一变速器输入轴(GE1)之间设置的第一摩擦离合器(C1),所述第二子变速器具有多个在第二变速器输入轴(GE2)与第二变速器输出轴(GA2)之间可切换的挡位(2,4,6,R)和在曲轴(KW)与第二变速器输入轴(GE2)之间设置的第二摩擦离合器(C2)和与第二子变速器(TG2)相关联的电机(EM)。为了能够减轻双离合器(DK)上的负载并且可以更简单地设计双离合器(DK),在两个子变速器(TG1,TG2)的挡位之间进行换挡之前,电机(EM)以扭矩重叠的方式从内燃机(ICE)接管驱动扭矩的至少一部分并且在摩擦功率至少减少时执行摩擦离合器(C1,C2)的摩擦接合的变换。
