The invention relates to a method for controlling a hybrid drive train (12) of a motor vehicle (10), comprising a first electric axle (20), a hybrid transmission (18) for a second axle, a planetary gear set (RS), the invention relates to a method for operating a hybrid transmission with a planetary gear set which is connected to a first transmission input shaft (24) for a first sub-transmission of the hybrid transmission and for connection to an internal combustion engine (16), to a second transmission input shaft (26) for a second sub-transmission, and to an electric drive machine (14), comprising the following steps: driving (S1) in a first gear by means of a hybrid drive train; detecting (S2) a state of the motor vehicle; and selecting (S3) one shift process from a plurality of available shift processes for shifting to another gear on the basis of the detected state of the motor vehicle for shifting to another gear. The invention also relates to a corresponding computer program product and to a controller (32).
本发明涉及一种用于控制机动车(10)的混合动力驱动传动系(12)的方法,该混合动力驱动传动系具有第一电动车轴(20)、用于第二车轴的混合动力变速器(18)、行星齿轮组(RS),该行星齿轮组与用于混合动力变速器的第一子变速器的且用于与内燃机(16)连接的第一变速器输入轴(24)、用于第二子变速器的第二变速器输入轴(26)和电驱动机(14)连接,该方法包括以下步骤:借助混合动力驱动传动系在第一挡位中行驶(S1);检测(S2)机动车的状态;并且基于检测到的机动车状态从多个可用的用于切换到另一挡位的换挡过程中选择(S3)一个换挡过程以切换到另一挡位。本发明还涉及一种相应的计算机程序产品和一种控制器(32)。
