The invention relates to a method for avoiding overload in a drive unit of an electric bicycle which is driven in combination by means of a manual pedaling crank (2) and an electric motor (6), in which a torque (MS) determined via the pedaling crank (2) corresponding to the driver's expectation is determined by a driving controller (11), a downstream motor controller (12) takes into account the torque for generating a motor assist energy by means of a motor control device (13) of the motor (6), said motor assist energy being generated by means of the motor control device (13) of the motor (6), said motor assist energy being generated if an overload situation is detected from a curve of at least one measured or estimated variable # imgabs0 #, said overload situation being detected from a curve of at least one measured or estimated variable # imgabs0 #. If the driver's desired torque (MS) is detected, the torque (MS) corresponding to the driver's desired torque is adjusted by a load torque controller (15) in order to generate a limited torque (MSlim), which is supplied as an adjusted setpoint to the motor controller (12) in order to prevent overload damage to the drive train components.

    本发明涉及一种用于在电动自行车的驱动单元中避免过载的方法,借助手动踩踏曲柄(2)以及电动机(6)以组合的方式驱动所述电动自行车,其中,由行驶调节器(11)确定经由所述踩踏曲柄(2)求取的、相应于驾驶员期望的扭矩(MS),连接在下游的电动机调节器(12)考虑所述扭矩,用于通过所述电动机(6)的电动机操控装置(13)生成电动机辅助能量,其中,如果从至少一个测量或估计参量#imgabs0#的变化曲线中探测到存在过载情况,则通过负载力矩调节器(15)调整相应于所述驾驶员期望的扭矩(MS),以便产生受限的扭矩(MS_lim),所述受限的扭矩作为所调整的额定值被提供给所述电动机调节器(12),用于防止驱动系部件上的过载损坏。
