In the proposed solution, the pressure level of the pump in the hydraulic transmission of the hydraulic work machine (1) or the power that can be supplied to the electric drive motor (20) of the electric work machine (1) is monitored, and/or the rotational speed at the output of the drive motor (20) of the work machine (1) and the rotation of the mobile device (13) of the work machine (1) are monitored. The pressure level of the hydraulic power transmission pump or the power that can be supplied to the electric drive motor (20) is compared to a lower threshold value to detect a fault condition, and/or the rotation speed at the output of the drive motor (20) is compared to the rotation of the mobile device (13) to also detect a fault condition. In the event that a fault condition is detected, a brake system of the work machine is controlled to apply a brake.

    在提出的解决方案中,液压作业机械(1)的液压传动系统中的泵的压力水平或能够供给至电动作业机械(1)的电驱动马达(20)的动力被监测,并且/或者作业机械(1)的驱动马达(20)的输出处的旋转速度和作业机械(1)的移动装置(13)的旋转被监测。液压动力传动泵的压力水平或能够供给至电驱动马达(20)的动力与较低阈值进行比较以检测故障情况,并且/或者驱动马达(20)的输出处的旋转速度与移动装置(13)的旋转进行比较也用以检测故障情况。在检测到故障情况的情况下,作业机械的制动系统被控制成应用制动器。
