The present invention relates to a method and device for controlling a vehicle, more particularly, the power train of a compacting machine for earth moving operations, comprising a hydraulic travel pump and a hydraulic travel motor. Control is effected according to a specified control profile when a specified driving operation is to be carried out in that an adjustment of the travel pump is carried out which is independent of the rotational speed of the internal combustion engine. This makes it possible to retain, on the one hand, the rotational speed of the internal combustion engine in the case of abrupt stops of movement or changes in the direction of movement and, on the other hand, to adapt the rotational speed of the engine in the case of somewhat longer uninterrupted pauses between two changes in the traveling behavior, wherein comparatively large fluctuations in the rotational speed are avoided.

The present invention relates to a self-propelled ground milling machine for treatment of ground surfaces by means of a milling device, a transportation means and a drive device for driving the transportation means and the milling device. The milling device is mounted on a ground milling machine frame and can be switched between a working position, in which the milling device is in operative contact with the ground surface and a maneuvering position, in which the milling device is not in operative contact with the ground surface. The drive device comprises a drive control unit, which controls the driving power of the drive device. The ground milling machine further comprises a ground milling machine control unit. The ground milling machine control unit controls the interaction of the drive device, the transportation means, and the milling device such that the driving power of the drive device in the maneuvering position of the milling device is automatically caused to be lower than the driving power of the drive device in the working position of the milling device while at least sufficient driving power for the transportation means is maintained.

A multipurpose compactor with an automatic safety system is provided. The automatic safety system comprises at least one transmitter and one receiver. The transmitter is coupled mechanically fixed to the multipurpose compactor and/or to a unit movable relative to the multipurpose compactor. The receiver is coupled fixedly to the movable unit and/or the multipurpose compactor.
