The invention relates to a control unit and method for a hybrid drive, which comprises an internal combustion engine and an electrical machine, the internal combustion engine comprising adjustment devices (for example, fully variable valve lift controllers, and/or valve opening actuators that can be switched on and off) at least for deactivating the intake and exhaust valve opening actuation. According to the invention, the control unit is designed in such a way (e.g. by means of a software program module in the form of a drag torque reduction functional module) that, in the case of at least one specified condition (in particular in the case of regeneration during unfired overrun or in the case of electric travel, in particular in the case of operation with high activation frequency of the internal combustion engine, e.g. in "charge sustaining" or HEV operation), the intake and exhaust valves are kept at least approximately (preferably completely) closed at least approximately simultaneously while the internal combustion engine is unfired. The internal combustion engine must be connected to the electrical machine. If there is a disconnect clutch, the disconnect clutch is brought into the closed state or remains closed.
本发明涉及用于混合动力驱动装置的控制单元和方法,该混合动力驱动装置包括内燃机和电机,其中,内燃机具有至少用于停用进气门和排气门的打开操作的调节装置(例如全可变气门升程控制装置和/或可开/关的气门打开执行器)。根据本发明,控制单元(例如通过以降低拖曳转矩功能模块形式的软件程序模块)设计成,使得在至少一个预定条件下(尤其是当在未点火的惯性运行中进行回收时,或尤其是在内燃机以高接通频率运行时、例如在“电量保持”或在HEV运行中电动行驶时)在未点火的内燃机中至少几乎同时并且至少几乎完全(优选完全)使进气门和排气门保持关闭。在此,内燃机必须与电机连接。如果在必要情况下存在分离离合器时,则该分离离合器闭合或保持闭合。
