The invention relates to a method for controlling an internal combustion engine of a drivetrain comprising a belt starter generator or an electric machine of a hybrid drivetrain for starting up theinternal combustion engine a cylinder and a piston running in the cylinder, which together bound a working space, wherein the working space is supplied with fresh air via inlet valves (2) with an intake tract, and is connected to an exhaust gas manifold via outlet valves; a system (1) for variably activating the inlet valves, wherein the system (1) for variably activating the inlet valves (2) ofthe internal combustion engine is actuated in such a way that the opening time and/or the closing time and/or the stroke of the inlet valves (2) are changed. During operation of the internal combustion engine with a negative drive torque and/or when powering down and/or when starting up the internal combustion engine the following strategy is applied: the valves (2) of individual working spaces or of all the working spaces are actuated in such a way that the transfer of fresh air from the intake tract to the exhaust gas manifold is controlled and that the drag torque of the internal combustion engine is reduced.
本发明涉及一种用于控制驱动系的内燃发动机的方法,该驱动系包括‑用于启动内燃发动机的混合动力驱动系的电机或皮带起动器发电机,‑气缸和在气缸中工作的活塞,气缸和活塞共同限界了做功腔,其中,做功腔经由进气门(2)利用吸气管段被供应新鲜空气,并且经由排气门与废气岐管处于连接中;‑用于可变地操纵进气门的系统(1),其中,对用于可变地操纵内燃发动机的进气门(2)的系统(1)进行驱控,从而改变进气门(2)的打开时间和/或闭合时间和/或升程。当内燃发动机以负的驱动力矩运行时和/或当关闭内燃发动机时和/或当启动内燃发动机时,采用以下策略:驱控各个或所有做功腔的进气门(2),从而管控新鲜空气从吸气管段向废气岐管的传输并降低内燃发动机的倒拖力矩。
