Abstract:
The invention relates to a method and device for controlling a creep operation of a vehicle with a hybrid drive (1), comprising a parallel hybrid drivetrain (2), with an internal combustion engine (3), at least one electric motor (5), a first switching element (4) in the form of a friction element between the internal combustion engine (3) and the electric motor (5), a gearbox (7), an output (26) and a second switching element (6) arranged between the electric motor (5) and the output (26). According to the invention, a simple, effective and component-friendly continuous creeping can be achieved without additional constructional or economic costs can be achieved, wherein the creeping operation is carried out with the internal combustion engine (3) running and both switching elements (4,6) simultaneously operating with slip, wherein the total operating power required to generate a required creeping torque is variably distributed over both switching elements (4, 6).
