Abstract (en)

[origin: WO2021123046A1] The invention relates to a method for coasting operation of a hybrid drivetrain (1) for a motor vehicle, in which an internal combustion engine (10) is separably connected through a first clutch (K0) to an electric traction motor (11), and the electric traction motor (11) for its part is separably connected via a second clutch (K1) to a transmission, wherein, for coasting operation, either the first clutch (K0) or the second clutch (K1) is disengaged and the decision as to which of the two clutches is disengaged is made as a function of one or more state parameters.
