  • Control method for a vehicle hybrid drivetrain
    Patent number: 11124175
    Abstract: A method for operating a hybrid drive train of a motor vehicle (X) which has a combustion engine (VM), a transmission (G), an electric machine (EM), as well as a separation clutch (KO) positioned between the combustion engine (VM) and the electric machine (EM). During a purely electric drive operation in which the separation clutch (KO) is disengaged and, when a gear is selected in the transmission (G), and during expectation, reaching, or exceeding a rotational speed difference of the separation clutch (KO) is larger or equal to a limit value, and/or in an expectation, reaching, or exceeding a rotational speed limit of the electric machine (EM), the separation clutch (KO) is engaged. Further, an electronic control unit (ECU) executes the method and a motor vehicle (X) having such an electronic control unit (ECU).
