Abstract (en)
[origin: WO2008098801A1] The invention relates to a method for operating a drive train (1) of a vehicle during trailing throttle operation using an internal combustion engine (2), an electric machine (3) and a transmission device (4). The electric machine (3) is disposed in the power flux between the internal combustion engine (2) and the transmission device (4). A shifting element (8) with continuously variable transmission capability is provided between the electric machine (3) and an output (5). A target output torque to be applied to the output (5) is dependent on a transmission capability of the shifting element (8). The transmission capability of the shifting element (8) is adjusted in a controlled manner as a function of the necessary target output torque such that the shifting element (8) has a transmission capability as is necessary for obtaining the target output torque at the output (5). A rotational speed of the electric machine (3) is adjusted in a controller manner during a shut-off process of the internal combustion engine (2) in order to maintain the shifting element (8) in a slipping operation at least during the shut-off process of the internal combustion engine (2) and guide the rotational speed of the internal combustion engine (2) to zero by means of the electric machine (3).
