Drivetrain for use in motor vehicle, has gearbox arranged between drive assembly and output, and hydraulic system supporting hydraulic pressurization of hydraulic pump of internal combustion engine during starting of combustion engine

摘要

The drivetrain (1) has a drive assembly provided with an internal combustion engine (2), and a gearbox (5) arranged between the drive assembly and an output (4). A hydraulic system (8) supports hydraulic pressurization of a hydraulic pump (7) of the internal combustion engine during starting of the internal combustion engine, where the hydraulic system is designed as a storage system i.e. electrohydraulic storage that forms a storage oil volume during operation of the internal combustion engine. A controller (9) controls the storage system to output the storage oil volume.
