Abstract: A hybrid electric vehicle (HEV) includes an engine, a first motor directly connected to the engine through a first shaft, a second motor directly connected to a second shaft, and an engine clutch of which one end is connected to the first shaft and the other end is connected to the second shaft so as to selectively connect the first shaft and the second shaft. The (HEV) includes a first controller unit configured to control each of the first motor and the second motor and a second controller unit configured to determine whether a preconfigured touch point learning condition is satisfied, control the first and second motors to respective first and second speeds when the learning condition is satisfied, and learn a touch point of the engine clutch on the basis of a torque change of the first motor or the second motor.

Abstract: A hybrid electric vehicle and a method for compensating a motor torque thereof, may include a hybrid control unit (HCU) including a processor and a non-transitory storage medium containing instructions executed by the processor. The processor is configured to start motor torque intervention upon entering a predetermined shift phase during shifting, to determine a motor torque compensation amount by reflecting engine torque according to engine torque reduction control, and to perform motor torque compensation control based on the motor torque compensation amount.

Abstract: A power transmission apparatus may include a first motor-generator including a first stator fixed to a first housing, and a first rotor; a second motor-generator including a second stator fixed to a second housing and a second rotor; a first planetary gear set including first and third rotation elements connected to the first rotor and a first wheel, respectively, and a third rotation element; a second planetary gear set including fourth, fifth and sixth rotation elements connected to the second rotor, a second wheel, and the third rotation element, respectively; a first clutch selectively locking up the first planetary gear set by selectively connecting two out of the first to third rotation elements; a second clutch selectively locking up the second planetary gear set by selectively connecting two of the fourth to sixth rotation elements; and a brake selectively fixing the third and sixth rotation elements to a third housing.
