Abstract
A soil compactor is described. The soil compactor includes at least two vibrating compacting rollers rotatable about a respective roller axis of rotation. The soil compactor further includes a vibration excitation arrangement assigned to each vibrating compacting roller of the at least two vibrating compacting rollers for generating a vibrating movement of the at least two vibrating compacting rollers. The soil compactor also includes a sensor arrangement assigned to the soil compactor for providing a feedback signal indicative of sound or a structural vibration of the soil compactor. The soil compactor yet further includes a control unit receiving the feedback signal for controlling at least one vibration excitation arrangement, based on the feedback signal, such as to act on a phase offset of the vibrating movements of the at least two vibrating compacting rollers with respect to one another.
