The invention relates to a method for operating an electrified drive train of a working machine, in which an electric motor of the drive train is drivingly coupled to at least one wheel of the working machine, in which the working machine is subjected to a downhill force during downhill travel, which causes an acceleration torque (100) on the working machine, and in a generator operating mode, the electric motor of the drive train is drivingly coupled to the at least one wheel of the working machine. The generator torque of the electric motor is offset from the acceleration torque, the maximum generator torque being dependent on the actual motor speed of the electric motor, and wherein an automated braking intervention (102) is carried out when the work machine is accelerated (101) as a result of the downhill force. The method according to the invention is characterized in that the actual motor speed is reduced by braking intervention until the maximum generator torque is at least as large as the acceleration torque at the reduced actual motor speed (104). The invention also relates to a corresponding electrified drive train of a work machine and to a corresponding work machine.

    本发明涉及用于运行作业机械的电气化驱动系的方法,其中,驱动系的电动马达与作业机械的至少一个车轮存在能传动的联接,其中,作业机械在下坡行驶时承受下坡力,其引起作业机械上的加速力矩(100),其中,在发电机运行模式下,电动马达的发电机力矩与加速力矩相抵,其中,最大发电机力矩依赖于电动马达的实际马达转速,并且其中,当作业机械由于下坡力而加速时(101)实施自动化的制动干预(102)。根据本发明方法的特征在于,通过制动干预降低实际马达转速直至最大发电机力矩在已降低的实际马达转速下至少与加速力矩一样大(104)。本发明还涉及作业机械的相应的电气化驱动系以及相应的作业机械。
