Abstract
A method for starting up a vehicle includes driving a first wheel with an internal combustion engine vehicle drive and driving a second wheel with a hydrostatic additional drive. The hydrostatic additional drive has an adjustable hydraulic pump driven by the internal combustion engine, and at least one hydraulic motor coupled hydraulically thereto. The method further includes increasing and regulating a supply pressure of the at least one hydraulic motor in dependence on an accelerator pedal; determining a non-zero rotational speed of the first wheel; and synchronizing a rotational speed of the second wheel with the determined rotational speed of the first wheel. The method further includes increasing and regulating a supply pressure of the at least one hydraulic motor in dependence on an accelerator pedal; determining a non-zero speed of the vehicle; and adapting a rotational speed of the second wheel to the determined speed.
