    Abstract: In motor double-drive mode, a first rotation speed (Np1) and a second rotation speed (Np2) as a drive shaft rotation speed are calculated from rotation speeds (Nm1, Nm2) of motors (MG1, MG2) on the assumption that an engine rotation speed is zero (S110). A state where a difference (Npl - Np2) between the first rotation speed and the second rotation speed is larger than a threshold (Npref) continues, and, when a malfunction counter (CW) becomes larger than a threshold (CWref), it is determined that there is a malfunction in a one-way clutch (CL1) or pinion gears (S140 to S180). At a start of the engine, it is determined that there is a malfunction in the one-way clutch (CL1) when the engine rotation speed (Ne) is normally increasing (S240), and it is determined that there is a malfunction in the pinion gears when the engine rotation speed (Ne) is not normally increasing (S260).

    Abstract: The invention relates to a method of drivingly engaging a first motor (4) of a dual motor drive unit (1; 100) with an output shaft (14) driven by a second motor (7) of the dual motor drive unit (1; 100), the method comprising the steps of:
    actuating a clutching device (9) for drivingly engaging the first motor (4) with the output shaft (14);
    synchronizing a rotational speed (32) of the first motor (4) with a rotational speed of the output shaft (14);
    when the rotational speed (32) of the first motor (4) and the rotational speed of the output shaft (14) are synchronized, reducing an output torque of the first motor (4); and
    when the clutching device (9) drivingly engages the first motor (4) with the output shaft (14), increasing the output torque of the first motor (4).
    The invention further relates to a dual motor drive unit (1; 100) for carrying out the method.
