The hybrid power assembly system comprises a hybrid power transmission, an internal combustion engine, a motor generator and a transmission system with at least one drivable driving wheel. The hybrid transmission is configured to receive a drive power of the internal combustion engine, i.e. An internal combustion engine drive power, and to receive a drive power of the motor generator, i.e. An electric drive power, and to output at least one or both drive powers to the drivetrain, and the hybrid transmission further has at least three gears, the invention relates to a hybrid transmission having three gears, which are formed from at least two different types of gears, having a switchable transmission, i.e., a shift transmission, which is provided for providing at least one of the three gears, i.e., a fixed-ratio gear, which is formed from the first type of gears, and which is provided for providing at least one of the three gears, i.e., a fixed-ratio gear, which is formed from the second type of gears. The gears of the first type each have a transmission ratio for the internal combustion engine and the motor generator with respect to the drive train connection, said transmission ratio being determined by the structural type of the gearshift transmission, and the hybrid transmission also has a rotational speed superposition transmission, and a drive arrangement for providing at least one of the three gears consisting of a second type of gears, i.e. A power split gear having a variable rotational speed ratio and a fixed torque ratio with respect to the internal combustion engine joint and the drivetrain joint, the power split gear being a gear having a variable rotational speed ratio and a fixed torque ratio with respect to the internal combustion engine joint and the drivetrain joint, the variable rotational speed ratio is formed in the hybrid transmission by means of a rotational speed superposition of a rotational speed provided by the internal combustion engine and a rotational speed provided by the motor generator, the hybrid transmission having at least one operating mode, in which a shift is carried out only between different types of gears.
