The present invention relates to a hybrid electric vehicle, which may distribute driving forces for each driving source more efficiently, and a driving control method therefor. The control method of the hybrid electric vehicle according to one embodiment of the present invention comprises: a step of determining an engine driving point in a hybrid electric vehicle (HEV) mode; and a step of determining a first torque for a first motor and a second torque for a second motor, respectively, based on an engine torque, required torque, and transmission input terminal's velocity according to the engine driving point. The first motor is directly connected to the engine. The second motor is directly connected to the transmission input terminal. The first and second motors can be connected in a specific driving mode using the engine's driving force.

    본 발명은 보다 효율적으로 구동원별로 구동력을 분배할 수 있는 하이브리드 자동차 및 그를 위한 주행 제어 방법에 관한 것이다. 본 발명의 일 실시예에 따른 하이브리드 자동차의 제어 방법은, HEV(Hybrid Electric Vehicle) 모드에서 엔진 운전점을 결정하는 단계; 및 상기 엔진 운전점에 따른 엔진 토크, 요구 토크 및 변속기 입력단의 속도를 기반으로 제1 모터에 대한 제1 토크 및 제2 모터에 대한 제2 토크를 각각 결정하는 단계를 포함하되, 상기 제1 모터와 상기 엔진은 직결되고, 상기 제2 모터는 상기 변속기 입력단과 직결되며, 상기 제1 모터와 상기 제2 모터는 상기 엔진의 구동력을 이용하는 특정 주행 모드에서 연결될 수 있다.
