摘要： The present disclosure relates to an emergency stop method for hybrid construction equipment and a brake control device, and more particularly, to an emergency stop method for hybrid construction equipment and a brake control device, which may confirm a failure occurrence location of the hybrid construction equipment, absorb inertial energy of the swing body using several functions for each generated failure location so as to stably stop the swing body in an emergency manner, and when the failure occurs in the hybrid construction equipment, create the brake pattern by using the swing speed or the front information, control a brake of the swing body by controlling a voltage control valve or a hydraulic valve in accordance with the created brake pattern, such that a user may smoothly stop the swing body in accordance with a desired stop speed profile.
摘要翻译：本公开涉及混合动力施工设备和制动控制装置的紧急停止方法，更具体地，涉及混合动力施工设备和制动控制装置的紧急停止方法，其可以确认混合动力施工设备的故障发生位置利用每个产生的故障位置的几个功能来吸收摆动体的惯性能量，以便以紧急方式稳定地停止摆动体，并且当在混合动力施工设备中发生故障时，通过使用摆动速度或者前部信息，通过根据所产生的制动模式控制电压控制阀或液压阀来控制摆动体的制动，使得使用者可以根据期望的停止速度曲线平滑地停止摆动体。
