The invention relates to a motor vehicle having at least two drive motors, at least one of which is an electric machine, having a high-pressure accumulator, an automatic transmission and an electronic control unit, the invention relates to an electronic control unit for an automatic transmission having at least one fixed gear ratio stage and at least one power split gear ratio stage and/or at least one tandem gear ratio stage for gear ratio adjustment towards the at least one fixed gear ratio stage, having a functional module, the invention relates to a method for controlling an internal combustion engine and an electric machine such that a torque curve of the following type can be predefined in the range of a transmission ratio adjustment between engagement of a shift element and load-bearing of the shift element in order to control the internal combustion engine and the electric machine:-the shift element to be engaged is loaded at a first point in time with a predefined torque gradient up to a second point in time; a first time at which at least a tooth-to-tooth position can be assumed,-limiting the predetermined torque to a maximum permissible torque from a second time to a third time during a predetermined waiting duration, and-limiting the predetermined torque to a maximum permissible torque after the end of the waiting duration or when the engaged state is identified,-limiting the maximum permissible torque from the second time to the third time during the predetermined waiting duration or when the engaged state is identified. The shifting element to be engaged continues to be carried with a previously specified torque gradient, preferably until a fully carried torque in the fixed gear is reached.

    本发明涉及一种具有至少两个驱动马达的机动车,至少一个驱动马达是电机,所述机动车具有高压蓄存器、自动变速器和电子控制单元,所述自动变速器具有至少一个固定传动比级和至少一个功率分流传动比级和/或至少一个用于朝向至少一个固定传动比级进行传动比调节的串联式传动比级,所述电子控制单元具有功能模块,使得在切换元件的挂入与切换元件的承载之间的传动比调节的范围内可以预定下述类型的转矩曲线,以便控制内燃机和电机:‑在第一时间点以预定的转矩梯度使待挂入的切换元件承载直至第二时间点,在所述第一时间点至少可以假定齿对齿位置,‑在预定的等待持续时段期间,从第二时间点直至第三时间点将预定的转矩限制到最大允许转矩,并且‑在等待持续时段结束之后或在识别挂入状态时,以之前预定的转矩梯度继续使待挂入的切换元件承载,优选直至达到完全承载的固定挡位中的转矩。
