METHOD FOR DRIVING A DRIVE TRAIN OF A VEHICLE AND APPARATUS FOR CARRYING OUT THE METHOD

摘要

The invention relates to a method and apparatus for driving a vehicle, in particular the drive train of a compaction machine for earthworks, having a hydraulic traction pump (12) and a hydraulic traction motor (11). The control is carried out in accordance with a predefined control profile when a predefined travelling mode is present, in that an adjustment of the traction pump that is independent of the rotational speed of the combustion engine (13) is generated. As a result, it is possible, firstly in the case of travel stoppages or travel direction changes occurring for a short time, to maintain the rotational speed of the internal combustion engine and, secondly, during somewhat longer lasting pauses between two changes of the driving behavior, to adapt the engine rotational speed, wherein larger fluctuations in rotational speed are avoided.
