ABSTRACT:
The invention relates to a soil compacting device comprising a motion detection device for detecting an actual value for the travelling motion of the soil compacting device. Inside a travel control device, the actual value is compared with a set value that is predetermined by the operator. When a difference between these two values is determined, the travel control device corrects the travelling motion by controlling a steering device or a drive of the soil compacting device. In another embodiment of the invention, a number of vibration plates are connected by the means of connecting elements to form a soil compacting system, which is also provided with a travel control device. The travel control device controls the individual drives in order to steer the entire soil compacting system.
