A hybrid electric vehicle comprising:
- an engine clutch connected at one end of the engine clutch to a first motor and connected at another end of the engine clutch to a second motor, the first motor being directly connected to an engine;
- a battery electrically connected to the first motor and the second motor;
- and
- a controller configured, when the engine is driven in an engaged state of the engine clutch, to:
- determine an operating point of the engine based on a predetermined efficiency map,
- determine total motor torque to be output by a motor unit comprising the first motor and the second motor based on the operating point of the engine, and
- determine an operating point of each of the first motor and the second motor based on total motor applied torque causing the motor unit to output the total motor torque and whether the battery is charged or discharged.
