The invention relates to a method for controlling a hybrid powertrain (10) for a motor vehicle, the hybrid powertrain (10) comprising an internal combustion engine (12), an electric machine (14), a hybrid transmission (16) and drive wheels, the hybrid transmission (16) having several shift units (S1; s2; (S3); s4), by means of which at least a first gear stage (G1c), a second gear stage (G2) and a third gear stage (G4) can occur, the transmission ratio between the crankshaft of the internal combustion engine (12) and the output shaft (AW) of the hybrid transmission continuously decreasing from the first gear stage (G1c) via the second gear stage (G2) to the third gear stage (G3), and the transmission ratio between the crankshaft of the internal combustion engine (12) and the output shaft (AW) of the hybrid transmission continuously decreasing from the first gear stage (G1c) via the third gear stage (G3) via the second gear stage (G2) to the third gear stage (G4). When operating in such a way that both the internal combustion engine (12) and the electric machine (14) introduce a drive torque for driving the drive wheel into the hybrid transmission, a third limit torque (G3R) for the third gear (G3) is set in the first mode and a second limit torque (G2H) for the second gear (G2) is set in the second mode, the maximum third limit torque (G3Rm) of the first mode is greater than the maximum second limit torque (G2Hm) of the second mode.
本发明涉及一种用于控制机动车用混合动力系(10)的方法,其中,混合动力系(10)包括内燃发动机(12)、电机(14)、混合变速器(16)和驱动轮,其中,混合变速器(16)具有若干换挡单元(S1;S2;S3;S4),借助于这些换挡单元能出现至少第一变速挡(G1c)、第二变速挡(G2)和第三变速挡(G4),其中,从第一变速挡(G1c)经第二变速挡(G2)到第三变速挡(G3)地在内燃发动机(12)的曲轴和混合变速器的输出轴(AW)之间的传动比连续减小,其中,当按照内燃发动机(12)和电机(14)都将用于驱动该驱动轮的驱动力矩传入混合变速器的方式运行时,在第一模式中设定用于第三变速挡(G3)的第三极限力矩(G3R),在第二模式中设定用于第二变速挡(G2)的第二极限力矩(G2H),其中,第一模式的最大第三极限力矩(G3Rm)大于第二模式的最大第二极限力矩(G2Hm)。
