METHOD AND DEVICE FOR CONTROLLING A CREEP MODE OF A VEHICLE COMPRISING A HYBRID DRIVE

摘要

The invention relates to a method for controlling a creep mode of a vehicle comprising a hybrid drive (1), a drive train (2) which comprises an internal combustion engine (3), an electric machine (5), a first gear-shift element (4) arranged between the internal combustion engine (3) and the electric machine (5), a transmission (7), a power take-off (26) and a second gear-shift element (6) arranged between the internal combustion engine (3) and the electric machine (5). The aim of the invention is to allow a temporally unlimited and yet clutch-friendly creep mode. The method according to the invention is characterized in that the creep mode is implemented by controlling the electric machine (5) and the second gear-shift element (6) in a cyclically alternating manner. A device for carrying out the method comprises control means which are used to implement a creep mode of the vehicle optionally by operating the second gear-shift element (6) in a slip mode or by operating the electric machine (5) in a creep mode.
