A method is provided for starting an internal combustion engine of a hybrid vehicle. The vehicle includes a single or a dual-clutch transmission for transmitting torque from the engine to the driving wheels; the transmission has at least one input shaft connected to a clutch. The single and dual-clutch transmission have each an output shaft and at least a first countershaft which are connectable to the first clutch or clutches, respectively. An electric machine is mechanically connected to the countershaft downstream of the clutches so that the clutches are interposed between the electric machine and the engine. The starting method involves detecting at least one engine related parameter to determine whether the electric machine is to be used for cranking the engine and opening the clutch to separate the electric machine from the engine. Subsequently, the at least one detected engine related parameter is used to select rotatable components to be used for assisting engine start. The selected components are rotated by connecting the countershaft to the clutch; and operating the electric machine. The clutch is then closed in order to start the engine. |
