    • The invention relates to a self-propelled construction machine, in particular a road-milling machine, recycler, stabilizer, or surface miner, comprising a machine frame (2), which is carried by a chassis (1), which has wheels or traveling units (1A, 1B). A milling roller (4) is arranged on the machine frame. The wheels or traveling units (1A, 1B) and the milling roller (4) are driven by a drive unit (8). Furthermore, the construction machine has a control unit (19) for controlling the drive unit (8) and a signal-capturing unit (18) for sensing at least one measured quantity (M(t)) characteristic of an operating state of the milling roller (4). The construction machine is distinguished in that the rotational speed of the milling roller (4) is adapted to the operating conditions of the construction machine in accordance with at least one measured quantity (M(t)) characteristic of a critical operating state of the milling roller in such a way that the milling roller is operated in a non-critical operating state. The adaptive control of the milling roller rotational speed makes allows for the construction machine to be operated at an optimal working point with respect to the milling roller rotational speed.
    • 本发明涉及一种自推式工程机械,尤其是一种路面铣刨机,回收器,稳定器或露天采矿机,其包括机架(2),该机架由底盘(1)承载,该底盘(1)具有车轮或行驶 单位(1A,1B)。 机架上设有铣刨辊(4)。 轮子或行走单元(1A,1B)和铣刨辊(4)由驱动单元(8)驱动。 此外,建筑机械具有用于控制驱动单元(8)的控制单元(19)和用于感测铣削操作状态的至少一个测量量(M(t))特征的信号捕获单元(18) 滚筒(4)。 该建筑机械的突出之处在于,铣刨辊(4)的转速根据铣刨的临界运行状态的至少一个测量量(M(t))特征与建筑机械的运行条件相适应 辊以这样的方式使得铣刨辊在非关键操作状态下操作。 铣刨辊转速的自适应控制使得施工机械可以在相对于铣刨辊转速的最佳工作点上运行。
