用于控制混合动力传动系中的分离离合器的方法和传动系
摘要：
本发明涉及一种混合动力传动系(1)和一种用于控制机动车的混合动力传动系(1)的摩擦离合器(4)的方法，所述混合动力传动系具有借助于飞轮(10)与用于传输发动机力矩的变速器的变速器输入轴(3)耦联的内燃机和启动内燃机的和/或驱动机动车的电机(5)，所述摩擦离合器(4)将由用于借助于电机(5)启动内燃机的启动力矩和在传动系(1)超速运行时作用于内燃机上的推进力矩形成的总力矩传输到内燃机上。为了能够可靠地运行所述传动系(1)并且避免由于高的总力矩所引起的摩擦离合器(4)的超尺寸，将施加到摩擦离合器(4)上的力矩限制于预设的、可经由摩擦离合器传输的传输力矩。
摘要（英）：

A hybrid drivetrain and method for controlling a friction clutch of a hybrid drivetrain of a motor vehicle having a combustion engine which is coupled by means of a freewheel to a transmission input shaft of a transmission to transmit the engine torque, and having an electric machine which starts the combustion engine and/or propels the motor vehicle, which friction clutch transmits to the combustion engine a summed torque formed of a starting torque for starting the combustion engine by means of the electric machine and a drag torque which acts on the combustion engine when the drivetrain is in drag mode. To be able to operate the friction clutch reliably and to avoid over-dimensioning of the friction clutch as a result of high summed torques, a torque present at the friction clutch is limited to a predefined transmission torque which can be transmitted via the friction clutch.
