Hybrid vehicle drive train controlling method for use during starting output drive, involves predetermining drive speed during starting moment source, where speed is small value fractionally larger than speed of shaft of drive

摘要

The method involves providing an electronic control unit (6) for controlling drive train components. A drive speed is predetermined by the control unit during starting a moment source (3), where the drive speed is around a predetermined small value fractionally larger than a speed of an input shaft of an output drive (5). A drive moment of the moment source is turned to the drive by a controllable transmission element (4) i.e. starting clutch, by increasing transmitted moment. The transmitted moment is increased by closing the transmission element.
