To provide a driving device for vehicles capable of preventing starting shock and starting slowness of an internal combustion engine.
A driving device includes a motor generator 3 capable of generating electric power by utilizing power of an internal combustion engine 2, a hydraulic clutch 7 capable of connecting/disconnecting power transmission between the internal combustion engine 2 and the motor generator 3, and operating by utilizing hydraulic pressure, and an oil pump 10 capable of supplying hydraulic pressure to the hydraulic clutch 7 by utilizing the power of the motor generator 3. The driving device actuates the oil pump 10 by the motor generator 3, in the process of starting the internal combustion engine 2, and subsequently causes the power of the motor generator 3 to be transmitted to the internal combustion engine 2, while subjecting the hydraulic clutch 7 to slip engagement from release state.
