Abstract:
The invention relates to a method and a device for controlling a creep mode of a vehicle having a hybrid drive system (1, 1′), having a parallel hybrid drivetrain (2, 2′) comprising an internal combustion engine (3), at least one electrical machine (5), a first switching element (4) designed as a frictional element and disposed between the internal combustion engine (3) and the electrical machine (5), by means of which the internal combustion engine (3) can be connected to the electrical machine (5), a gearbox (7), an output (26), and at least one second switching element (6) designed as a frictional element and disposed between the electrical machine (5) and the output (26), by means of which the electrical machine (5) can be operationally connected to the output (26). In order to allow low-cost, effective long-term creeping that is gentle on the components, and thereby ensures reliable availability of electrical energy for electrical loads of the vehicle, the creep mode is alternately implemented by an internal combustion engine creep mode generated by means of operating at least one switching element (6, 27) in slip, and an electrical motor creep mode at least supported by means of the electrical machine (5).
