Abstract
A driving apparatus includes a first transmission mechanism receiving mechanical power from an engine output shaft by a first input shaft, a second transmission mechanism receiving the mechanical power from the engine output shaft and a motor by a second input shaft, and a first clutch capable of engaging the engine output shaft with the first input shaft. When performing cranking of an internal-combustion engine, an ECU selects a gear position of the first transmission mechanism and the second transmission mechanism to reduce speed of the mechanical power received by the second input shaft and transmit the power to the first input shaft, and puts the first clutch into an engaging state. The speed of the mechanical power from the motor is reduced by the first and second transmission mechanisms to increase torque, and power is transmitted to the engine output shaft through the first clutch.
