Abstract
The apparatus may include an engine configured to supply a drive torque to the vehicle. A first motor generator directly connected to the engine and generates electric power and supplies the drive torque to a transmission. A clutch is interposed between the first motor generator and the transmission and selectively transmits rotational power between the first motor generator and the transmission. A second motor generator is electrically connected to the first motor generator and generates electric power and supplies the drive torque to the transmission at all times. A battery supplies the electric power to the first and second motor generators and is charged by the first and second motor generators.

An apparatus for driving a plug-in hybrid vehicle, comprising:
- an engine configured to supply a drive torque to the vehicle;
- a first motor generator directly connected to the engine and configured to generate electric power and supply the drive torque to a transmission;
- a clutch disposed between the first motor generator and the transmission and configured to selectively transmit rotational power between the first motor generator and the transmission;
- a second motor generator electrically connected to the first motor generator and configured to generate electric power and to supply the drive torque to the transmission continually;
- and
- a battery configured to supply the electric power to the first and second motor generators and charged by the first and second motor generators.
A method of controlling an apparatus for driving a plug-in hybrid vehicle, in which the apparatus includes a planetary gear set, the planetary gear set having a sun gear, a ring gear, and a planetary carrier, a first motor generator supplied with rotational power of an engine of the vehicle, a second motor generator electrically connected to the first motor generator, a battery configured to supply electric power to the first and second motor generators, and a clutch interposed between the first motor generator and the ring gear, wherein
- when a driving condition of the vehicle is set to an electric vehicle (EV) mode, a brake is operated to rotate or fix the ring gear and to release the clutch.
