Abstract
A method of drivingly engaging a first motor of a dual motor drive unit with an output shaft driven by a second motor of the dual motor drive unit includes actuating a clutching device for drivingly engaging the first motor with the output shaft. Next, a rotational speed of the first motor is synchronized with a rotational speed of the output shaft. When the rotational speed of the first motor and the rotational speed of the output shaft are synchronized, an output torque of the first motor is reduced. When the clutching device drivingly engages the first motor with the output shaft, the output torque of the first motor is increased. The invention further relates to a dual motor drive unit for carrying out the method.
