A method for shutting down an internal combustion engine of a powertrain of a vehicle wherein the powertrain further comprises a transmission and a clutch device connected to and arranged between the internal combustion engine and the transmission. The clutch arrangement includes a first clutch arranged to couple the internal combustion engine to a first input shaft of the transmission and a second clutch arranged to couple the internal combustion engine to a second input shaft of the transmission. The first input shaft is drivably connected to a first set of gears and the second input shaft is drivably connected to a second set of gears. The first and second sets of gears are connected to an output shaft of the transmission. The method includes the steps of: controlling the internal combustion engine in an idle state when the vehicle is in a rest position, wherein the first clutch and the second clutch are arranged in an open position; engaging the first input shaft with a first preselected gear of the first set of gears and engaging the second input shaft with a second preselected gear of the second set of gears; initiating an engine shutdown instruction; the internal combustion engine is stopped by at least partially closing the first clutch and the second clutch to simultaneously introduce torque transfer to the first clutch and the second clutch to a transmission stagnation state for controlled engine stop, wherein engine inertia of the internal combustion engine is collected in the first clutch and the second clutch.

    一种用于关闭车辆的动力传动系统的内燃发动机的方法,其中,动力传动系统还包括变速器和离合器装置,该离合器装置连接至内燃发动机和变速器并布置在二者之间。离合器装置包括被布置成将内燃发动机联接至变速器的第一输入轴的第一离合器和被布置成将内燃发动机联接至变速器的第二输入轴的第二离合器。第一输入轴能够驱动地连接至第一组档位,第二输入轴能够驱动地连接至第二组档位。第一组档位和第二组档位连接至变速器的输出轴。该方法包括如下步骤:当车辆处于静止位置时将内燃发动机控制在怠速状态,其中第一离合器和第二离合器布置在打开位置;使第一输入轴与第一组档位中的第一预选取档位接合,并且,使第二输入轴与第二组档位中的第二预选取档位接合;发起发动机关闭指令;通过至少部分地闭合第一离合器和第二离合器以同时将传递至第一离合器和第二离合器的扭矩传递引入到用于受控的发动机停止的变速器停滞状态,而使得内燃发动机停止,其中内燃发动机的发动机惯性被收集在第一离合器和第二离合器中。
