Description

엔진-모터 결합 구조 및 이를 포함하는 하이브리드 시스템{CONNECTING STRUCTURE FOR ENGINE AND MOTOR, AND HYBRID SYSTEM INCLUDING THE SAME} Engine-motor combination structure and hybrid system including same

본 발명은 엔진-모터 결합 구조 및 이를 포함하는 하이브리드 시스템에 관한 것이다.The present invention relates to an engine-motor coupling structure and a hybrid system including the same.

하이브리드 차량(hybrid electric vehicle)은 내연기관(internal combustion engine)과 배터리 전원을 함께 사용한다. 즉, 하이브리드 차량은 내연기관의 동력과 모터의 동력을 효율적으로 조합하여 사용한다.Hybrid electric vehicles use both an internal combustion engine and battery power. That is, the hybrid vehicle efficiently combines and uses the power of the internal combustion engine and the power of the motor.

하이브리드 차량은 엔진과 모터의 파워 분담비에 따라 마일드(mild) 타입과 하드(hard) 타입으로 구분할 수 있다. 마일드 타입의 하이브리드 차량(또는 마일드 하이브리드 차량)은 알터네이터(alternator) 대신에 엔진을 시동하거나 상기 엔진의 출력에 의해 발전하는 시동 발전기(mild hybrid starter & generator; MHSG)를 포함한다. 하드 타입의 하이브리드 차량은 엔진을 시동하거나 상기 엔진의 출력에 의해 발전하는 시동 발전기와 차량을 구동하는 구동 모터를 각각 별도로 포함한다.A hybrid vehicle may be classified into a mild type and a hard type according to the power sharing ratio between the engine and the motor. The mild type hybrid vehicle (or mild hybrid vehicle) includes a mild hybrid starter & generator (MHSG) that starts an engine instead of an alternator or generates electricity by an output of the engine. The hard-type hybrid vehicle separately includes a starter generator that starts an engine or generates electricity by an output of the engine and a drive motor that drives the vehicle.

마일드 하이브리드 차량은 MHSG의 토크만으로 차량을 구동시키는 주행 모드는 없지만, MHSG를 이용하여 주행 상태에 따라 엔진 토크를 보조할 수 있으며, 회생제동을 통해 배터리(예를 들어, 48 V 배터리)를 충전할 수 있다. 이에 따라, 마일드 하이브리드 차량의 연비가 향상될 수 있다.The mild hybrid vehicle does not have a driving mode that drives the vehicle only with the torque of the MHSG, but the MHSG can be used to assist the engine torque depending on the driving condition, and the battery (eg, a 48 V battery) can be charged through regenerative braking. can Accordingly, fuel efficiency of the mild hybrid vehicle may be improved.
