The invention relates to a method for operating an automatic transmission of a hybrid vehicle having a traction motor, on which a drag torque (18) is reserved, starting from a maximum available electrical power for driving the traction motor, and having an internal combustion engine, according to the invention, a characteristic curve cluster (10) having a respective curve (12) for a respective gear of an automatic transmission of the hybrid vehicle is constructed, and the characteristic curve cluster (10) is adapted as a function of the drag torque (18) to be reserved in such a way that each curve (12) is reduced with the drag torque (18) to be reserved, and a switching logic is specified, in which each curve (12) is reduced with the drag torque (18) to be reserved. A respective shift point (14) for shifting the automatic transmission is defined at the intersection of the curves (12) of the adjacent gears of the adapted characteristic curve cluster (10), at which the automatic transmission is shifted by means of a shift logic.

    本发明涉及一种用于运行混合动力车辆的自动变速器的方法,混合动力车辆具有牵引电机和内燃机,在牵引电机上预留拖曳力矩(18),从用于驱动牵引电机的最大可用电功率出发,构建具有用于混合动力车辆的自动变速器的相应挡位的相应曲线(12)的特性曲线簇(10),并且根据要预留的拖曳力矩(18)适配特性曲线簇(10),其方式为每个曲线(12)以要预留的拖曳力矩(18)降低,并且预定切换逻辑,在切换逻辑中,在适配的特性曲线簇(10)的相邻挡位的曲线(12)的交点处定义用于切换自动变速器的相应切换点(14),借助切换逻辑在相应切换点(14)中切换自动变速器。
