See full text

A series hybrid transmission includes a first motor device for driving a first shaft, a second motor device for driving a second shaft. Drive gears on the first and second shafts can be simultaneously engaged in the same or different gears and torque from the two motor devices can he multiplied. When shifting up or down, the drive gear on one of the shafts can be disengaged while the drive gear on the other one of the shafts remains engaged to avoid interruption in application of torque.
