즉, 클러치(4)가 입력축(S1)과 회전력 전달 기어열(5)의 제 1 기어를 연결하여 입력축(S1)의 회전력이 회전력 전달 기어열(5)을 통해 출력축(S2)에 전달되도록 하거나, 입력축(S1)과 회전력 전달 기어열(5)을 분리하여 입력축(S1)의 회전력이 회전력 전달 기어열(5)로 전달되지 않도록 함으로써 회전력이 출력축(S2)에 전달되지 않도록 한다. 또한, 클러치(4)는 입력축(S1)이 제 1 모터 제너레이터(2)의 전달기어에 연결되도록 하여, 입력축(S2)의 회전력이 제 1 모터 제너레이터(2)에 전달되도록 함으로써 제 1 모터 제너레이터(2)가 발전기로 동작하도록 할 수 있다.That is, the clutch 4 connects the input shaft S1 and the first gear of the rotational force transmission gear train 5 so that the rotational force of the input shaft S1 is transmitted to the output shaft S2 through the rotational force transmission gear train 5 or , By separating the input shaft S1 and the rotational force transmission gear train 5 so that the rotational force of the input shaft S1 is not transmitted to the rotational force transmission gear train 5, the rotational force is not transmitted to the output shaft S2. In addition, the clutch 4 allows the input shaft S1 to be connected to the transmission gear of the first motor generator 2, so that the rotational force of the input shaft S2 is transmitted to the first motor generator 2, so that the first motor generator ( 2) can be operated as a generator.

감속유닛(6)은 유성 기어로 이루어져 유성기어를 통해 제 2 모터 제너레이터(3)의 회전력이 감속되어 출력축(S2)을 통해 출력된다. 감속유닛(6)인 유성 기어는 출력축(S2)과 동심을 이루도록 구성되며, 유성 기어의 선 기어가 제 2 모터 제너레이터(3)에 연결되고, 유성 기어의 캐리어가 회전력 전달 기어열(5)의 제 2 기어와 연결된다. 또한, 유성 기어의 링 기어가 감속유닛(6)의 하우징에 의해 구속된다.The reduction unit 6 is made of a planetary gear, and the rotational force of the second motor generator 3 is decelerated through the planetary gear and output through the output shaft S2. The planetary gear which is the reduction unit 6 is configured to be concentric with the output shaft S2, the sun gear of the planetary gear is connected to the second motor generator 3, and the carrier of the planetary gear is of the rotational force transmission gear train 5 It is connected to the second gear.

상기와 같은 구성을 갖춘 하이브리드 차량은 SERIES 모드, PARALLEL 모드, ENG 모드, EV 모드 및 REV 모드를 수행한다.The hybrid vehicle having the above-described configuration performs SERIES mode, PARALLEL mode, ENG mode, EV mode, and REV mode.

SERIES 모드는 하이브리드 차량의 저속 및 도심 운행을 위한 모드이며, PARALLEL 모드는 하이브리드 차량의 고속, 추월 및 등판 운행을 위한 모드이며, ENG 모드는 하이브리드 차량의 고속 운행을 위한 모드이며, EV 모드는 하이브리드 차량의 저속 및 제동을 위한 모드이며, REV 모드는 하이브리드 차량의 후진 운행을 위한 모드이다.SERIES mode is a mode for low-speed and downtown driving of a hybrid vehicle, PARALLEL mode is a mode for high-speed, overtaking and climbing of a hybrid vehicle, ENG mode is a mode for high-speed driving of a hybrid vehicle, and EV mode is a hybrid vehicle It is a mode for low speed and braking, and the REV mode is a mode for reverse driving of a hybrid vehicle.

다음은 이와 같이 구성된 하이브리드 차량의 운행 모드들에 대해 설명한다.The following describes the driving modes of the hybrid vehicle configured as described above.

도 2에는 하이브리드 차량의 파워 트레인이 SERIES 모드를 수행할 경우가 도시되어 있다. 2 shows a case where the power train of the hybrid vehicle performs the SERIES mode.

도시한 바와 같이 하이브리드 차량이 저속 및 도심 운행할 경우 SERIES 모드가 수행된다. As shown, when the hybrid vehicle is traveling at low speed and in the city, the SERIES mode is performed.

도 2에 도시한 바와 같이 SERIES 모드에서는 엔진이 동작하여 입력축(S1)을 회전시키고, 제 1 모터 제너레이터(2)가 발전기로 동작하고, 제 2 모터 제너레이터(3)가 모터로 동작한다.As shown in FIG. 2, in the SERIES mode, the engine operates to rotate the input shaft S1, the first motor generator 2 operates as a generator, and the second motor generator 3 operates as a motor.

SERIES 모드에서 클러치(4)는 입력축(S1)과 회전력 전달 기어열(5)을 분리하여 입력축(S1)의 회전력이 회전력 전달 기어열(5)에 전달되지 않도록 하고, 입력축(S1)과 제 1 모터 제너레이터(2)를 연결하여 입력축(S1)의 회전력이 제 1 모터 제너레이터(2)에 전달되도록 하여 제 1 모터 제너레이터(2)가 발전기로 동작하도록 한다.In the SERIES mode, the clutch 4 separates the input shaft S1 and the rotational force transmission gear train 5 so that the rotational force of the input shaft S1 is not transmitted to the rotational force transmission gear train 5, and the input shaft S1 and the first By connecting the motor generator 2, the rotational force of the input shaft S1 is transmitted to the first motor generator 2 so that the first motor generator 2 operates as a generator.

따라서 엔진(1)에 의해 출력축(S2)이 회전하면, 발전기로 동작하는 제 1 모터 제너레이터(2)는 발전기로 동작하여 전력을 발생시키고, 발생한 전력은 배터리(7)에 전달되어 배터리(7)가 충전된다. Therefore, when the output shaft S2 is rotated by the engine 1, the first motor generator 2 operating as a generator operates as a generator to generate electric power, and the generated power is transmitted to the battery 7 and the battery 7 Is charged.

또한, 배터리(7)에 충전된 전력 중 일부가 모터로 동작하는 제 2 모터 제너레이터(3)로 전달되어, 제 2 모터 제너레이터(3)에서 회전력이 발생한다.In addition, a part of the electric power charged in the battery 7 is transmitted to the second motor generator 3 operating as a motor, and rotational force is generated in the second motor generator 3.

제 2 모터 제너레이터(3)에서 발생한 회전력은 감속유닛(6)을 통해 출력축(S2)에 전달되어 하이브리드 차량의 휠을 회전시키는데 사용된다. The rotational force generated by the second motor generator 3 is transmitted to the output shaft S2 through the reduction unit 6 and is used to rotate the wheel of the hybrid vehicle.

따라서, 하이브리드 차량이 저속 및 도심 운행할 수 있다.Thus, the hybrid vehicle can operate at low speed and downtown.

도 3에는 하이브리드 차량의 파워 트레인이 PARALLEL 모드를 수행할 경우가 도시되어 있다. 3 illustrates a case where the power train of the hybrid vehicle performs the PARALLEL mode.

도시한 바와 같이 하이브리드 차량이 고속, 추월 및 등판 운행할 경우에는 PARALLEL 모드가 수행된다.As illustrated, when the hybrid vehicle is running at high speed, overtaking, and climbing, the PARALLEL mode is performed.

PARALLEL 모드에서는 엔진(1)이 동작하여 입력축(S1)을 회전시키고, 제 1 모터 제너레이터(2)는 동작하지 않고, 제 2 모터 제너레이터(3)는 모터로 동작한다.In the PARALLEL mode, the engine 1 operates to rotate the input shaft S1, the first motor generator 2 does not operate, and the second motor generator 3 operates as a motor.

PARALLEL 모드에서 클러치(4)는 입력축(S1)과 회전력 전달 기어열(5)을 연결하여 입력축(S1)의 회전력이 회전력 전달 기어열(5)에 전달되도록 한다.In the PARALLEL mode, the clutch 4 connects the input shaft S1 and the rotational force transmission gear train 5 so that the rotational force of the input shaft S1 is transmitted to the rotational force transmission gear train 5.

따라서 엔진(1)에 의해 출력축(S2)이 회전하면, 클러치(4)를 통해 회전력이 회전력 전달 기어열(5)에 전달되어, 회전력 전달 기어열(5)을 통해 출력축(S2)에 전달된다.Therefore, when the output shaft S2 is rotated by the engine 1, the rotational force is transmitted to the rotational force transmission gear train 5 through the clutch 4, and is transmitted to the output shaft S2 through the rotational force transmission gear train 5. .

또한, 이와 동시에 배터리(7)에 충전된 전력 중 일부가 모터로 동작하는 제 2 모터 제너레이터(3)로 전달되어, 제 2 모터 제너레이터(3)에서 회전력이 발생한다.In addition, at the same time, a part of the electric power charged in the battery 7 is transmitted to the second motor generator 3 operating as a motor, and rotational force is generated in the second motor generator 3.

제 2 모터 제너레이터(3)에서 발생한 회전력은 감속유닛(6)을 통해 출력축(S2)에 전달된다.The rotational force generated in the second motor generator 3 is transmitted to the output shaft S2 through the reduction unit 6.

따라서, 출력축(S2)에는 엔진(1)에서 발생한 회전력과 제 1 모터 제너레이터(2)에서 발생한 회전력이 동시에 전달되므로 하이브리드 차량이 고속, 추월 및 등판 운행할 수 있다. Accordingly, since the rotational force generated by the engine 1 and the rotational force generated by the first motor generator 2 are simultaneously transmitted to the output shaft S2, the hybrid vehicle can operate at high speed, overtaking, and climbing.

도 4에는 하이브리드 차량의 파워 트레인이 ENG 모드를 수행할 경우가 도시되어 있다. 4 shows a case where the power train of the hybrid vehicle performs the ENG mode.

도시한 바와 같이 하이브리드 차량이 고속 운행할 경우에는 ENG 모드가 수행된다.As shown, when the hybrid vehicle is traveling at high speed, the ENG mode is performed.

ENG 모드에서는 엔진(1)이 동작하여 입력축(S1)을 회전시키고, 제 1 모터 제너레이터(2) 및 제 2 모터 제너레이터(3)는 동작하지 않는다.In the ENG mode, the engine 1 operates to rotate the input shaft S1, and the first motor generator 2 and the second motor generator 3 do not operate.

ENG 모드에서 클러치(4)는 입력축(S1)과 회전력 전달 기어열(5)을 연결하여 입력축(S1)의 회전력이 회전력 전달 기어열(5)에 전달되도록 한다.In the ENG mode, the clutch 4 connects the input shaft S1 and the rotational force transmission gear train 5 so that the rotational force of the input shaft S1 is transmitted to the rotational force transmission gear train 5.

따라서 엔진(1)에 의해 출력축(S2)이 회전하면, 클러치(4)를 통해 회전력이 회전력 전달 기어열(5)에 전달되고, 회전력 전달 기어열(5)를 통해 출력축(S2)에 전달된다. 즉, ENG 모드에서는 엔진(1)에서 발생한 회전력이 그대로 출력축(S2)에 전달된다.Therefore, when the output shaft S2 is rotated by the engine 1, the rotational force is transmitted to the rotational force transmission gear train 5 through the clutch 4, and is transmitted to the output shaft S2 through the rotational force transmission gear train 5. . That is, in the ENG mode, the rotational force generated by the engine 1 is transmitted to the output shaft S2 as it is.

따라서 하이브리드 차량이 고속 운행할 수 있다.Therefore, the hybrid vehicle can operate at high speed.

도 5에는 하이브리드 차량의 파워 트레인이 EV 모드를 수행할 경우가 도시되어 있다. 5 illustrates a case where the power train of the hybrid vehicle performs the EV mode.

하이브리드 차량이 저속 및 회생 운행할 경우에는 EV 모드가 수행된다.When the hybrid vehicle operates at low speed and regenerative operation, the EV mode is performed.

EV 모드에서는 엔진(1) 및 제 1 모터 제너레이터(2)는 동작하지 않고, 제 2 모터 제너레이터(3)가 모터 또는 발전기로 동작한다.In the EV mode, the engine 1 and the first motor generator 2 do not operate, and the second motor generator 3 operates as a motor or a generator.

따라서, 하이브리드 차량이 저속 운행할 경우에는 배터리(7)에 충전된 전력의 일부가 제 2 모터 제너레이터(3)에 전달되어 제 2 모터 제너레이터(3)가 회전력을 발생시킨다. Therefore, when the hybrid vehicle is running at a low speed, a part of the electric power charged in the battery 7 is transmitted to the second motor generator 3, so that the second motor generator 3 generates rotational force.

제 2 모터 제너레이터(3)에서 발생한 회전력은 감속유닛(6)을 통해 출력축(S2)에 전달된다. The rotational force generated in the second motor generator 3 is transmitted to the output shaft S2 through the reduction unit 6.

따라서, 하이브리드 차량이 저속 운행할 수 있다. Therefore, the hybrid vehicle can operate at low speed.

또한 EV 모드에서 하이브리드 차량이 제동 운행할 경우에는 제 2 모터 제너레이터(3)가 발전기로 동작하여 전력을 발생시키고, 제 2 모터 제너레이터(3)에서 발생한 전력은 배터리(7)에 전달되어 배터리(7)가 충전된다.In addition, in the EV mode, when the hybrid vehicle is braking, the second motor generator 3 operates as a generator to generate electric power, and the electric power generated by the second motor generator 3 is transferred to the battery 7 and the battery 7 ) Is charged.

도 6에는 하이브리드 차량의 파워 트레인이 REV 모드를 수행할 경우가 도시되어 있다. 6 illustrates a case where the power train of the hybrid vehicle performs the REV mode.

도시한 바와 같이 하이브리드 차량이 후진 운행할 경우에는 REV 모드가 수행된다.As shown in the figure, when the hybrid vehicle runs backward, the REV mode is performed.

REV 모드에서는 엔진 및 제 1 모터 제너레이터(2)는 동작하지 않고, 제 2 모터 제너레이터(3)가 모터로 동작한다. In REV mode, the engine and the first motor generator 2 do not operate, and the second motor generator 3 operates as a motor.

따라서, 하이브리드 차량이 저속 운행할 경우에는 배터리(7)에 충전된 전력의 일부가 제 2 모터 제너레이터(3)에 전달되어 제 2 모터 제너레이터(3)가 회전력을 발생시킨다. REV 모드에서 제 2 모터 제너레이터(3)는 EV 모드와는 반대 방향으로 회전력을 발생시킨다. Therefore, when the hybrid vehicle is running at a low speed, a part of the electric power charged in the battery 7 is transmitted to the second motor generator 3, so that the second motor generator 3 generates rotational force. In the REV mode, the second motor generator 3 generates rotational force in a direction opposite to the EV mode.

제 2 모터 제너레이터(3)에서 발생한 회전력은 감속유닛(6)을 통해 출력축(S2)에 전달된다. The rotational force generated in the second motor generator 3 is transmitted to the output shaft S2 through the reduction unit 6.

따라서, 하이브리드 차량이 후진 운행할 수 있다. Therefore, the hybrid vehicle can run backward.
