Abstract: A method for closed-loop control of a controlled variable to a given reference variable. The actual value and/or the measured actual value of the controlled variable is/are influenced by a fluctuating effect with a certain periodicity. The controlled variable is readjusted if there is a control difference between the reference variable and an average value of the actual value averaged over the period duration of the periodicity. Measurement values are determined within the period duration of each periodicity at measurement time points in a certain controller cycle, these measurement values correlating with a respective actual value or corresponding to the actual value, and/or being adapted to determine therefrom the control difference between the reference variable and the average value of the actual value. The control difference is determined at each measurement time point and the controlled variable is selectively readjusted.

Abstract: A torque-transmitting arrangement for the drive train of a muscle-power-operated vehicle with auxiliary motor includes an output shaft, a first input shaft for the transmission of a torque generated by muscle power to the output shaft, a second input shaft for the transmission of a torque generated by the auxiliary motor to the output shaft, and a freewheel function, which prevents a user from having to concomitantly rotate the auxiliary motor when the auxiliary motor is inactive. A mechanical clutch transmits a torque from the second input shaft to the output shaft if, at the first input shaft, a torque prevails which acts in a drive direction of rotation on the output shaft, and transmits no torque from the second input shaft to the output shaft if, at the first input shaft, a torque prevails which acts on the output shaft counter to the drive direction of rotation.
