System and method of the automatic compaction of soil
First Claim
1. A soil compacting system, comprising:
- a mobile, generally hand guided steerable soil compacting device; and
a control device;
the control device including;
a surface definition device allowing a local operator to establish a surface to be compacted by locally defining associated surface boundaries;
a position detection device for detecting the current position of the soil compacting device, at least in the vicinity of the surface boundaries;
a path planning device for setting a predetermination for a travel path, on the basis of the defined surface area and on the compaction needs of the surface, in such a way that the soil compacting device travels over at least substantially the entire surface, a sufficient number of times to achieve complete compaction of the soil in the surface;
a motion controller for changing a direction of travel by predetermining a target value for a traveling movement of the soil compacting device, such that the soil compacting device does not cross the respective surface boundary, but rather continues its travel within the surface, along the predetermined travel path, the motion controller changing the direction of travel by adjusting operation of at least one vibration excitation device.

Abstract
The invention relates to a soil compacting system which comprises a travelling and steerable soil compacting device and a control device. The control device is provided with an area definition device which allows a user to establish an area to be compacted and the area boundaries. A position detecting device detects the actual position of the soil compacting device. A traveler changes the direction of travel of the soil compacting device by presetting a standard value for a travelling movement of the soil compacting device in such manner that the soil compacting device does not travel past the respective area boundary but continues its travel within the area. A path planning device may be provided for fixing a presetting for a travel way which makes sure that the soil compacting device, when keeping to the preset travel way, travels at least once completely across the area to be compacted.

27. A method for automated soil compacting, comprising the steps of:
-
locally defining surface boundaries of a surface to be compacted by a normally hand guided soil compacting device, using a locally positioned surface definition device; planning a travel path of the compacting device, on the basis of the defined surface area and on the compaction needs of the surface, in such a way that the soil compacting device travels over at least substantially the entire surface a sufficient number of times to achieve complete compaction of the soil in the surface; controlling at least one vibration excitation device to cause the soil compacting device to automatically travel along the travel path within the surface boundaries in a generally straight line such that the position of the compacting device relative to a work surface is defined solely by the surface boundary; detecting an approach of the soil compacting device to one of the surface boundaries; and automatically modifying of the direction of travel of the soil compacting device from the generally straight line in such a way that the soil compacting device does not cross the respective surface boundary, but rather continues its travel within the surface in a direction crossing the generally straight line.

28. A method for automated soil compacting, comprising the steps of:
-
locally defining surface boundaries of a surface to be compacted by a normally hand guided soil compaction device by physically defining a perimeter of the surface to be compacted, and storing data representing the surface boundaries in a surface definition device; planning a predetermination for a travel path on the basis of the defined surface area and on the compaction needs of the surface, in such a way that the soil compacting device travels over substantially the entire surface to be compacted at a sufficient number of times to achieve complete compaction of the soil in the surface while adhering to the predetermined travel path; controlling at least one vibration excitation device of the soil compacting device to cause the soil compacting device to automatically travel along the predetermined travel path after the surface boundaries have been defined. - View Dependent Claims (29, 30)
