Description

하이브리드 자동차의 구동 시스템{Drive system of hybrid electric vehicle} [0001] The present invention relates to a drive system for a hybrid vehicle,

본 발명은 하이브리드 자동차의 구동 시스템에 관한 것으로, 더욱 상세하게는 차량을 주행시키기 위해 엔진과 전기모터를 사용하여 전륜과 후륜을 구동할 수 있는 하이브리드 자동차의 E-4WD 시스템에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a drive system of a hybrid vehicle, and more particularly, to an E-4WD system of a hybrid vehicle capable of driving front wheels and rear wheels using an engine and an electric motor to drive a vehicle.

일반적으로 하이브리드 자동차는 화석연료를 사용하는 내연기관 엔진(ICE:Internal Combustion Engine)과 전기에너지를 사용하는 전기모터를 구동원으로 사용하여 주행하는 차량으로, 주행시 화석연료의 에너지와 전기에너지를 함께 사용할 수 있으므로 배기가스 저감 및 연비 향상이 가능해지는 친환경 자동차이다.In general, a hybrid vehicle is a vehicle that uses an internal combustion engine (ICE) that uses fossil fuel and an electric motor that uses electric energy as a driving source. It can use both energy and electric energy of fossil fuel Therefore, it is an eco-friendly automobile that can reduce exhaust gas and improve fuel efficiency.

하이브리드 자동차의 파워트레인 형태로는 전기모터가 변속기 측에 배치된 TMED(Transmission Mounted Electric Device) 방식이 잘 알려져 있다.As a powertrain type of a hybrid vehicle, a TMED (Transmission Mounted Electric Device) system in which an electric motor is disposed on the transmission side is well known.

통상의 TMED 방식에서는 전기모터의 출력 측에 변속기가 배치되고 엔진과 전기모터 사이에 엔진 클러치가 배치되어, 엔진 클러치의 결합 상태에서 엔진과 전기모터의 동력이 변속기를 통해 구동륜인 전륜에 전달될 수 있도록 되어 있다.In a typical TMED system, a transmission is disposed on the output side of the electric motor, and an engine clutch is disposed between the engine and the electric motor. In the engaged state of the engine clutch, the power of the engine and the electric motor can be transmitted to the front wheels Respectively.

또한, TMED 방식의 2WD(2 Wheel Drive) 하이브리드 자동차에서는 차량의 두 구동원인 엔진과 전기모터를 구동륜인 전륜 측에 동력 전달 가능하게 함께 배치하고, 차량 주행시 엔진과 전기모터의 토크를 오버레이(overlay)하여 변속기를 통해 전달하는 방식으로 전륜의 구동토크를 제어한다. In addition, in a 2-wheel drive (2-wheel drive) hybrid vehicle of the TMED type, an engine and an electric motor, which are two driving motors of the vehicle, are disposed together so as to transmit power to the front wheels, And controls the drive torque of the front wheels in such a manner as to transmit them through the transmission.

도 1은 하이브리드 자동차의 파워트레인 구성을 나타낸 도면으로서, 차량을 구동하는 전기모터(이하 '구동모터'라 칭함)가 변속기 측에 붙어 있는 TMED 방식의 파워트레인 구성을 예시하고 있다. 1 is a diagram showing a power train configuration of a hybrid vehicle, which illustrates a TMED powertrain configuration in which an electric motor (hereinafter referred to as a 'drive motor') for driving a vehicle is attached to the transmission side.

도 1에 나타낸 바와 같이, 하이브리드 자동차의 파워트레인 구성은, 차량 주행을 위한 구동원으로서 직렬로 배치되는 엔진(1)과 구동모터(3); 엔진(1)과 구동모터(3) 사이에 동력을 선택적으로 연결 또는 차단하도록 배치되는 엔진 클러치(2); 엔진(1) 및 구동모터(3)의 동력을 변속하여 구동축으로 전달하는 변속기(4); 엔진(1)과 동력 전달 가능하게 직결된 하이브리드 스타터-제너레이터(HSG:Hybrid Starter and Generator, 이하 'HSG'라 칭함)(5)를 포함한다.As shown in Fig. 1, the power train configuration of a hybrid vehicle includes an engine 1 and a drive motor 3, which are arranged in series as a drive source for running the vehicle; An engine clutch (2) arranged to selectively connect or disconnect power between the engine (1) and the drive motor (3); A transmission 4 for shifting the power of the engine 1 and the drive motor 3 to transmit the power to the drive shaft; And a hybrid starter and generator (HSG) 5 directly connected to the engine 1 so as to transmit power.

이러한 구성에서 엔진 클러치(2)는 결합 및 분리의 선택적인 작동을 통해 차량을 구동하는 두 구동원, 즉 엔진(1)과 구동모터(3) 사이에 동력을 연결하거나 차단하게 된다.In this configuration, the engine clutch 2 is connected or disconnected between the two driving sources for driving the vehicle, that is, between the engine 1 and the driving motor 3 through the selective operation of engagement and disengagement.

상기 구동모터(3)는 차량 주행시 엔진(1)과 함께 또는 단독으로 차량을 구동하는 구동수단으로 사용되며, 차량 제동시나 관성에 의한 타행 주행시에는 구동모터(3)가 발전기로 작동하여 배터리(7)를 충전하는 에너지 회생 모드가 수행된다.The drive motor 3 is used as a drive means for driving the vehicle together with the engine 1 when the vehicle is running, and when the vehicle is braked or driven by inertia, the drive motor 3 operates as a generator, Is performed in the energy regeneration mode.

또한, 차량의 동력원(전력원)이 되는 배터리(7)가 인버터(6)를 통해 차량의 모터, 즉 상기 구동모터(3)와 HSG(5)에 충, 방전 가능하게 연결되는데, 인버터(6)는 구동모터(3)와 HSG(5)의 구동을 위해 배터리(7)의 직류전류를 3상 교류전류로 변환하여 구동모터와 HSG에 인가한다. A battery 7 serving as a power source of the vehicle is connected to the motor of the vehicle through the inverter 6 so as to discharge and charge the HSG 5 with the drive motor 3. The inverter 6 Converts the direct current of the battery 7 into a three-phase alternating current for driving the drive motor 3 and the HSG 5, and applies the three-phase alternating current to the drive motor and the HSG.

상기 HSG(5)는 시동모터와 발전기가 별도로 장착되는 일반 내연기관 자동차와 달리 하이브리드 자동차에서 시동모터와 발전기의 통합된 기능을 수행하는 장치로서, 구동시 자체 동력을 벨트 및 풀리 등의 동력전달기구를 통해 엔진(1)에 전달하여 엔진을 시동하거나, 엔진(1)에서 전달되는 회전력으로 발전을 수행하며, 발전 작동시 생성되는 전기에너지로 배터리(7)를 충전한다.

한편, 도 1은 전륜을 구동륜으로 하는 2WD 하이브리드 자동차의 구동 시스템을 나타낸 것으로, 도 1에 예시된 2WD 전륜 구동 차량의 구동 시스템을 기반으로 하는 4륜 구동(4WD:4 Wheel Drive) 하이브리드 자동차의 구동 시스템이 제시된 바 있다.1 shows a driving system of a 2WD hybrid vehicle having a front wheel as a drive wheel, which is driven by a 4WD (4WD) hybrid vehicle based on the driving system of the 2WD front wheel drive vehicle illustrated in FIG. 1 The system has been proposed.

도 2는 종래기술에 따른 E-4WD 시스템의 구성을 간략히 도시한 도면으로, 도시된 바와 같이 기계적 동력장치 부분인 프로펠러 샤프트를 제거하고, 전륜(F) 측 구동원인 엔진(1)과 구동모터(MG1:3)에 더하여 후륜(R)에 구동모터(MG2:9)를 추가로 장착하여 E-4WD(Electric-4WD) 기능을 구현한다.FIG. 2 is a view schematically showing a configuration of an E-4WD system according to the related art. As shown in FIG. 2, a propeller shaft, which is a mechanical power unit, is removed and an engine 1 and a drive motor 4WD (Electric-4WD) function by additionally mounting a drive motor MG2: 9 to the rear wheel R in addition to the MG1: MG1: 3.

상기와 같이 E-4WD 시스템이 적용된 하이브리드 자동차는 전륜(F)과 후륜(R)에 각각 독립적인 구동수단을 가지고 있으며, 각각의 구동수단이 주행 조건에 따라 독립적으로 구동되거나 함께 구동될 수 있다.As described above, the hybrid vehicle to which the E-4WD system is applied has independent driving means for the front wheel F and the rear wheel R, and each driving means can be independently driven or driven together according to driving conditions.

이와 같은 E-4WD 시스템은 기존의 2WD 시스템에서 큰 변경 없이 후륜 모터(9)를 추가하는 것으로 4WD 기능을 구현할 수 있으므로 개발이 용이하다는 장점이 있다.Such an E-4WD system is advantageous in that it can be easily developed since the 4WD function can be implemented by adding the rear wheel motor 9 without major modification in the existing 2WD system.

그러나, 후륜 모터(9)를 이용하는 운전점 제어가 어렵고, 후륜 모터를 이용하는 운전점 제어가 수행될 때 손실이 커서 시스템 효율이 낮으므로 후륜 모터 추가로 인한 연비 향상의 효과가 크지 않다는 단점이 있다.However, it is difficult to control the operating point using the rear wheel motor 9, and when operating point control using the rear wheel motor is performed, loss is large and system efficiency is low.

또한, 기존의 2WD 하이브리드 시스템을 최적화하여 변경하지 아니하고 후륜 구동을 위한 모터(9)로 전륜 모터(3)와 마찬가지로 대용량 모터를 사용하고 있는바, 전, 후륜 모터(3,9)의 기능 중복(redundancy) 등으로 인해 원가 및 중량 상승의 문제점이 나타나고 있다.In addition, a large-capacity motor is used as the front wheel motor 3 as the motor 9 for rear wheel drive without optimizing and changing the conventional 2WD hybrid system. redundancy, etc., are causing cost and weight increase problems.

또한, 도 2와 같은 E-4WD 시스템에서 후륜 모터(9)만으로 회생제동을 실시할 경우 차량 안정성이 저하되므로 후륜 모터를 이용하는 회생제동의 제한이 불가피하며, 이 또한 후륜 모터 추가로 인한 연비 향상의 효과를 감소시키는 요인이 되고 있다.
In addition, in the E-4WD system as shown in Fig. 2, when the regenerative braking is performed using only the rear wheel motor 9, the stability of the vehicle is lowered, so restricting braking using the rear wheel motor is inevitably restricted. It is becoming a factor to reduce the effect.

한국공개특허 제10-2014-0053701호(2014.5.8.)Korean Patent Publication No. 10-2014-0053701 (Aug. 8, 2014)

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 창출한 것으로서, 전륜과 후륜 구동을 위한 엔진과 모터의 적절한 조합을 통하여 시스템 효율이 향상될 수 있고, 회생제동량 증대 및 연비 향상을 가능하게 하는 하이브리드 자동차의 구동 시스템을 제공하는데 그 목적이 있다.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made in an effort to solve the above problems, and an object of the present invention is to provide an engine control apparatus and a control method thereof that can improve system efficiency through appropriate combination of an engine and a motor for front- And to provide a drive system for a hybrid vehicle.

상기한 목적을 달성하기 위하여, 본 발명에 따르면, 전륜의 좌측륜과 우측륜에 각각 설치되는 인휠 모터; 후륜을 구동시키기 위한 엔진; 상기 엔진의 출력 측에 배치되어 엔진 동력의 속도를 변속하여 출력하는 변속기; 상기 엔진과 변속기 사이에 동력 전달 가능하게 배치되는 모터 제너레이터; 및 상기 변속기와 후륜의 구동축 사이의 동력전달경로 상에 설치되어 변속기와 후륜 사이의 동력 전달을 단속하는 동력단속수단을 포함하는 하이브리드 자동차의 구동 시스템을 제공한다.In order to achieve the above object, according to the present invention, there is provided an in-wheel motor, comprising: an in-wheel motor installed on left and right wheels of a front wheel; An engine for driving rear wheels; A transmission disposed on an output side of the engine for shifting and outputting a speed of engine power; A motor generator arranged to be able to transmit power between the engine and the transmission; And power interrupting means provided on a power transmission path between the transmission and the drive shaft of the rear wheels for interrupting transmission of power between the transmission and the rear wheels.

여기서, 상기 엔진과 변속기가 하나의 동력전달축을 통해 직결되고, 상기 엔진과 변속기 사이의 동력전달축에 모터 제너레이터의 회전자가 구성되어 상기 모터 제너레이터가 엔진 및 변속기에 직결된 구조가 되도록 함이 바람직하다.Here, it is preferable that the engine and the transmission are directly connected through a single power transmitting shaft, and a rotor of the motor generator is formed in a power transmission shaft between the engine and the transmission so that the motor generator is directly connected to the engine and the transmission .

또한, 상기 변속기의 출력축이 프로펠러축을 통해 후륜의 구동축에 동력 전달 가능하게 연결되고, 상기 동력단속수단이 프로펠러축 상에 설치되거나 프로펠러축이 연결된 차동장치의 출력축과 후륜의 구동축 사이에 설치될 수 있다.The output shaft of the transmission may be connected to a drive shaft of a rear wheel through a propeller shaft so that the power interrupting means may be installed on a propeller shaft or may be installed between an output shaft of a differential device to which a propeller shaft is connected and a drive shaft of a rear wheel .

또한, HEV 모드 주행시, 차량 내 제어기에 의해, 엔진과 후륜 사이의 동력 전달이 가능해지도록 동력단속수단의 작동이 제어된 상태에서, 엔진이 구동되어 엔진 동력이 후륜에 전달되고, 인휠 모터가 구동되어 인휠 모터의 동력으로 전륜이 구동될 수 있다.In the HEV mode, the engine is driven to transmit the engine power to the rear wheels while the operation of the power interrupting means is controlled by the in-vehicle controller so that the power transmission between the engine and the rear wheels becomes possible, and the in- The front wheel can be driven by the power of the in-wheel motor.

또한, 에너지 회생 모드에서 전륜의 인휠 모터를 통해 에너지 회생이 수행될 때, 차량 내 제어기에 의해 변속기와 후륜 사이의 동력 전달을 차단하도록 동력단속수단의 작동이 제어될 수 있다.Further, when the energy regeneration is performed through the in-wheel motor of the front wheel in the energy regeneration mode, the operation of the power interrupting means can be controlled by the in-vehicle controller to interrupt power transmission between the transmission and the rear wheel.

또한, EV 모드 주행시, 차량 내 제어기에 의해, 전륜에 설치된 인휠 모터가 구동되어 인휠 모터의 동력으로 차량이 구동되고, 변속기와 후륜 사이의 동력 전달을 차단하도록 동력단속수단의 작동이 제어되며, 엔진이 구동되어 엔진 동력으로 모터 제너레이터가 발전 작동되면서 배터리 충전이 이루어질 수 있다.
In the EV mode, the in-vehicle motor driven by the in-vehicle motor is driven by the in-vehicle motor to drive the vehicle with the power of the in-wheel motor, and the operation of the power interrupting means is controlled so as to block the transmission of power between the transmission and the rear wheel. So that the battery can be charged while the motor generator is operated by the engine power.

이로써, 본 발명에 따른 하이브리드 자동차의 구동 시스템에서는 엔진과 변속기 사이의 클러치를 삭제하여 클러치로 인한 엔진과 변속기 사이의 구동 손실 발생을 방지할 수 있고, 엔진과 변속기 사이의 모터 제너레이터를 이용하여 기존의 HSG를 대체할 수 있으므로 부품 수 축소, 원가 절감 및 중량 저감을 달성할 수 있게 된다.Thus, in the drive system of the hybrid vehicle according to the present invention, the clutch between the engine and the transmission can be eliminated to prevent the occurrence of drive loss between the engine and the transmission due to the clutch, HSG can be replaced, so that the number of components can be reduced, cost can be reduced, and weight reduction can be achieved.

또한, 엔진과 전륜의 인휠 모터로 차량을 구동하는 4WD 방식의 HEV 모드 주행, 그리고 엔진과 변속기 사이의 모터 제너레이터를 발전기로 사용하면서 전륜의 인휠 모터로 차량을 구동하는 직렬 모드(EV 모드) 주행이 가능함에 따라, 저용량 HSG를 사용하는 종래의 전륜 TMED 시스템이 가지는 고질적인 문제점인 등판 주행 및 도심 정체 주행시 연비 저하의 문제점이 해결될 수 있게 된다. In addition, the 4WD HEV mode driving the vehicle with the engine and the front wheel in-wheel motor, and the serial mode (EV mode) driving the vehicle with the front wheel in-wheel motor while using the motor generator between the engine and the transmission as the generator. As a result, it is possible to solve the problems of the backlash driving and the fuel consumption deterioration when the vehicle is running in the center of the city, which is a chronic problem of the conventional front wheel TMED system using the low capacity HSG.

또한, 출력에 제한이 있는 모터를 사용하여 전륜을 구동하고 출력에 여유가 있는 엔진으로 후륜을 구동할 수 있으므로 선회 및 등판 주행시 후륜에 더 큰 토크가 인가되도록 할 수 있고, 이상적인 비율에 가까운 전, 후륜 토크 분배가 구현될 수 있다.In addition, since the rear wheel can be driven by an engine having a limited output, by driving a front wheel using a motor having a limited output, a larger torque can be applied to the rear wheel at the time of turning and backing, Rear wheel torque distribution can be implemented.

특히, 전륜의 인휠 모터 장착으로 차량의 동력 성능이 개선될 수 있는데, 예컨대 종래에 비해 높은 구배의 눈길 등판로에서도 등판이 가능해지는 등 차량의 등판 성능이 향상될 수 있고, 추가적인 인휠 모터 장착으로 제로백 성능이 개선될 수 있으며, 전륜의 인휠 모터를 이용하여 토크 벡터링(torque vectoring) 기능을 구현하는 것 또한 가능하다.Particularly, the power performance of the vehicle can be improved by installing an in-wheel motor of the front wheel. For example, it is possible to improve the back-up performance of the vehicle, Performance can be improved, and it is also possible to implement a torque vectoring function using an in-wheel motor of the front wheel.

또한, 구동 손실 및 변속이 없는 인휠 모터를 전륜에 설치하여 회생제동 효율의 극대화가 가능해지는바, 종래의 TMED 시스템에 비해 회생제동 효율을 크게 개선할 수 있게 된다.In addition, an in-wheel motor having no drive loss and no shifting can be provided on the front wheels to maximize the regenerative braking efficiency, which makes it possible to significantly improve the regenerative braking efficiency as compared with the conventional TMED system.

또한, 본 발명의 구동 시스템에서는 후륜으로의 동력 전달을 차단하는 디커플러와 같은 동력단속수단을 적용하여 EV 모드 주행시 동력단속수단을 오픈함으로써 프로펠러축의 회전을 방지할 수 있고, 이에 구동 손실이 최소화되는 EV 모드를 구현할 수 있게 된다.
Further, in the drive system of the present invention, the power interrupting means such as a decoupler which interrupts the power transmission to the rear wheels is applied to open the power interrupting means during EV mode travel, thereby preventing rotation of the propeller shaft, It is possible to implement the EV mode.

본 발명은 차량을 주행시키기 위해 엔진과 전기모터를 사용하여 전륜과 후륜을 구동할 수 있는 하이브리드 자동차의 E-4WD 시스템에 관한 것이다.The present invention relates to an E-4WD system of a hybrid vehicle capable of driving front wheels and rear wheels using an engine and an electric motor to drive a vehicle.

특히, 본 발명은 차량을 구동하는 구동원인 엔진과 모터의 적절한 조합을 통하여 기존의 E-4WD 시스템에 비해 시스템 효율이 향상될 수 있고, 동력 성능을 개선함은 물론 차량 연비를 향상시킬 수 있는 하이브리드 자동차의 4륜 구동(4WD) 시스템을 제공하고자 하는 것이다.Particularly, according to the present invention, the system efficiency can be improved as compared with the existing E-4WD system through appropriate combination of the engine and the motor that are driving the vehicle, and the hybrid performance, which improves the power performance, To provide a four-wheel drive (4WD) system for an automobile.

이를 위해, 본 발명에 따른 구동 시스템은 엔진 동력으로 후륜을 구동하는 후륜 구동 베이스의 차량에서 전륜의 좌측륜과 우측륜에 각각 인휠(in-wheel) 모터를 장착한 구성을 가지며, 엔진 동력이 전달되도록 한 후륜이 주 구동륜으로 사용되면서 인휠 모터로 전륜을 구동하도록 구성된다.To this end, the drive system according to the present invention has a structure in which an in-wheel motor is mounted on each of the left and right wheels of a front wheel in a vehicle of a rear wheel drive base that drives rear wheels with engine power, So that the front wheel is driven by the in-wheel motor while the rear wheel is used as the main driving wheel.

또한, 본 발명에 따른 구동 시스템에서는 후륜 구동을 위한 엔진과 변속기 사이에 모터 제너레이터(MG:Motor Generator)를 장착하고, 엔진으로부터 후륜으로의 동력 전달이 이루어지는 동력전달경로 상에 동력단속수단을 배치한다.Further, in the drive system according to the present invention, a motor generator (MG) is mounted between the engine for rear wheel drive and the transmission, and the power interrupting means is disposed on the power transmission path through which power is transmitted from the engine to the rear wheels .

이러한 본 발명의 실시예에 따른 구동 시스템에 대해 도 3을 참조하여 좀더 상세히 설명하면 다음과 같다.The driving system according to the embodiment of the present invention will be described in more detail with reference to FIG.

도 3은 본 발명의 실시예에 따른 구동 시스템의 구성을 나타내는 도면으로서, 도시된 바와 같이 본 발명의 실시예에 따른 구동 시스템은 후륜(R)을 구동하기 위한 엔진(11)을 포함한다.Fig. 3 is a diagram showing a configuration of a drive system according to an embodiment of the present invention. As shown in Fig. 3, the drive system according to the embodiment of the present invention includes an engine 11 for driving the rear wheel R.

여기서, 엔진(11)이 후륜(R)을 구동시킬 수 있도록 엔진(11)과 후륜(R)의 구동축(17) 사이에 동력을 전달할 수 있는 동력전달경로가 형성되는데, 엔진 동력이 전달되는 동력전달경로 상에 모터 제너레이터(MG:12)와 변속기(13)가 차례로 배치되고, 변속기(13)가 후륜(R)의 구동축(17)에 동력 전달 가능하게 연결된다.Here, a power transmission path for transmitting power between the engine 11 and the drive shaft 17 of the rear wheel R is formed so that the engine 11 can drive the rear wheel R. The power transmission path for transmitting the engine power A motor generator MG 12 and a transmission 13 are disposed in order on the transmission path and the transmission 13 is connected to the drive shaft 17 of the rear wheel R so as to transmit power.

즉, 엔진(11)과 모터 제너레이터(12), 변속기(13)가 서로 동력 전달 가능하도록 직렬 배치되는 것으로서, 엔진(11)의 출력 측에 모터 제너레이터(12)가, 모터 제너레이터(12)의 출력 측에 변속기(13)가 배치되어, 동력전달경로 상에서 모터 제너레이터(12)가 엔진(11)과 변속기(13) 사이에 위치되도록 한 것이다. That is, the engine 11, the motor generator 12, and the transmission 13 are arranged in series so as to be able to transmit power to each other. The motor generator 12 is connected to the output side of the engine 11, So that the motor generator 12 is positioned between the engine 11 and the transmission 13 on the power transmission path.

이러한 배치 구성에서 엔진(11)의 출력축과 모터 제너레이터(12)의 회전축(모터 제너레이터 입력축)이 동력 전달 가능하게 연결되고, 모터 제너레이터(12)의 회전축(모터 제너레이터 출력축)과 변속기(13)의 입력축이 동력 전달 가능하게 연결된다.In this arrangement, the output shaft of the engine 11 is connected to the rotation shaft (motor generator input shaft) of the motor generator 12 so as to be able to transmit power, and the output shaft of the engine 11 is connected to the output shaft of the motor generator 12 Is connected for power transmission.

이때, 엔진(11)의 출력축과 모터 제너레이터(12)의 회전축이 직결될 수도 있으나, 엔진(11)의 출력축과 모터 제너레이터(12)의 회전축 사이에 동력을 연결하거나 차단하는 미도시된 클러치가 개재될 수도 있다.At this time, although the output shaft of the engine 11 and the rotation shaft of the motor generator 12 may be directly connected, a clutch (not shown) for connecting or disconnecting power between the output shaft of the engine 11 and the rotation shaft of the motor generator 12, .

상기 엔진(11)의 출력축과 모터 제너레이터(12)의 회전축이 직결된 구조에서는 엔진(11)의 출력축과 변속기(13)의 입력축 사이의 축이 모터 제너레이터(12)의 회전자(rotor) 축이 되고, 이 축에 모터 제너레이터(12)의 회전자 구성요소가 장착된다. In the structure in which the output shaft of the engine 11 is directly connected to the rotation shaft of the motor generator 12, the shaft between the output shaft of the engine 11 and the input shaft of the transmission 13 is connected to the rotor shaft of the motor generator 12 And the rotor component of motor generator 12 is mounted on this shaft.

결국, 엔진(11)과 변속기(13)가 하나의 동력전달축을 통해 직결된 구성을 가지게 되며, 클러치를 삭제하여 엔진(11)과 변속기(13)가 직결된 구성에서는 엔진(11)과 변속기(13) 사이의 구동 손실이 발생하는 것을 방지할 수 있다.As a result, the engine 11 and the transmission 13 are directly connected via the single power transmission shaft. In the structure in which the clutch 11 is disengaged and the engine 11 and the transmission 13 are directly connected, the engine 11 and the transmission 13 can be prevented from being generated.

또한, 엔진(11)과 변속기(13) 사이의 동력전달축에 모터 제너레이터(12)의 회전자를 구성하여 모터 제너레이터(12)가 엔진(11)에 직결된 구성에서는, 상기 모터 제너레이터(12)가 엔진 시동 및 발전을 위해 사용되던 기존의 HSG 기능을 수행할 수 있으므로, HSG 삭제를 통한 부품 수 축소가 가능해지고, 원가 절감 및 중량 저감의 이점이 있게 된다.In the configuration in which the motor generator 12 is directly connected to the engine 11 by constituting the rotor of the motor generator 12 on the power transmission shaft between the engine 11 and the transmission 13, Can perform the conventional HSG function used for starting and developing the engine, so that it is possible to reduce the number of components by eliminating the HSG, and there is an advantage of cost reduction and weight reduction.

또한, 상기한 엔진(11)과 모터 제너레이터(12), 변속기(13)가 차체 전측의 엔진룸에 장착되는 경우에는 통상의 후륜 구동 차량과 마찬가지로 변속기(13)의 출력축이 프로펠러축(propeller shaft)(14)을 통해 후륜(R)의 구동축(17)에 동력 전달 가능하게 연결될 수 있다. When the engine 11, the motor generator 12 and the transmission 13 are mounted in the engine room on the front side of the vehicle body, the output shaft of the transmission 13 is connected to a propeller shaft, Can be connected to the drive shaft (17) of the rear wheel (R) through a drive shaft (14) so as to transmit power.

상기 변속기(13)는 자동변속기(AT:Automatic Transmission), 자동화 수동변속기(AMT:Automatic Manual Transmission), 또는 듀얼 클러치 변속기(DCT:Double Clutch Transmission) 등이 될 수 있다.The transmission 13 may be an Automatic Transmission (AT), an Automatic Manual Transmission (AMT), or a Double Clutch Transmission (DCT).

또한, 상기 변속기(13)는 엔진(11)으로부터 출력되는 토크를 완충시키는 역할을 수행하는 토션 댐퍼를 포함하는 변속기가 될 수 있고, 통상의 토크 컨버터를 포함하거나 토크 컨버터가 삭제된 형태의 자동변속기가 될 수도 있다.The transmission 13 may be a transmission including a torsion damper that functions to buffer torque output from the engine 11 and may include a normal torque converter or an automatic transmission .

또한, 상기 변속기(13)는 변속단수에 있어서 인휠 모터(18)의 용량이 충분히 큰 경우 저속단을 삭제한 것이 사용될 수 있는데, 예를 들어 1~6속의 변속단수를 가진 통상의 6단 자동변속기에서 1단을 삭제하여 2~6속의 변속단수를 사용하거나 R단을 삭제한 자동변속기가 적용 가능하며, 이를 통해 변속기의 부피 및 가격을 낮출 수 있다.If the capacity of the in-wheel motor 18 is sufficiently large in the speed change stage, the transmission 13 may be used in which the low speed stage is eliminated. For example, a normal six-speed automatic transmission , It is possible to apply the automatic transmission that eliminates the R-stage by using the 2- to 6-speed transmission stages, thereby reducing the volume and the price of the transmission.

한편, 상기와 같이 후륜(R)을 구동시키기 위한 구동수단과 더불어, 전륜(F)을 구동시키기 위한 구동수단으로서 전륜(F)의 좌측륜과 우측륜에는 각각 인휠 모터(18)가 장착된다.The in-wheel motor 18 is mounted on the left and right wheels of the front wheel F as driving means for driving the front wheel F, in addition to the driving means for driving the rear wheel R as described above.

또한, 엔진(11)과 후륜(R) 사이의 동력전달경로, 보다 상세히는 변속기(13) 출력 측과 후륜(R) 사이의 동력전달경로 상에 선택적으로 동력을 연결하거나 차단하는 동력단속수단(15)이 배치된다.A power transmission path between the engine 11 and the rear wheel R and more specifically a power interrupting means for selectively connecting or disconnecting power on the power transmission path between the output side of the transmission 13 and the rear wheel R 15 are disposed.

상기 동력단속수단(15)은 축과 축 사이에 동력을 연결하거나 차단하도록 구성되는 통상의 디커플러(decoupler) 또는 클러치가 될 수 있으며, 변속기(13)의 출력축과 동력 전달 가능하게 연결된 프로펠러축(14) 상에 설치되거나, 프로펠러축(14)이 연결된 차동장치(16)의 좌, 우 출력축과 후륜(R)의 구동축(17) 사이, 즉 차동장치(16)의 좌, 우 출력축과 후륜(R)의 좌측륜 및 우측륜의 구동축(17) 사이에 각각 설치될 수 있다.The power interrupting means 15 may be a conventional decoupler or clutch configured to connect or disconnect power between the shaft and the shaft and may include a propeller shaft (not shown) coupled to the output shaft of the transmission 13 for power transmission Or between the left and right output shafts of the differential device 16 to which the propeller shaft 14 is connected and the drive shaft 17 of the rear wheel R, that is, the left and right output shafts of the differential device 16 and the rear wheels R and the drive shaft 17 of the right and left wheels, respectively.

이와 같이 본 발명의 실시예에 따른 구동 시스템의 구성에 대해 설명하였는바, 엔진(11)과 변속기(13) 사이의 모터 제너레이터(12) 및 전륜(F)에 장착된 각 인휠 모터(18)는 인버터 시스템(21)를 통해 차량의 에너지 저장장치(ESS:Energy Storage System), 즉 동력원(전력원)이 되는 고전압 메인 배터리(22)에 충, 방전 가능하게 연결되고, 에너지 회생 모드 또는 직렬 모드(Series Mode) 주행시와 같이 각 모터(12,18)가 발전기로 작동할 경우 모터의 발전작동으로 생성되는 전기에너지에 의해 배터리(22)가 충전될 수 있도록 되어 있다. The motor generator 12 between the engine 11 and the transmission 13 and the respective in-wheel motor 18 mounted on the front wheel F have the same structure as that of the in- Is connected to the high voltage main battery 22 which is an energy storage system (ESS: Energy Storage System) of the vehicle, that is, a power source (electric power source), through an inverter system 21 and is connected in an energy regenerative mode or a serial mode Series Mode) When each of the motors 12 and 18 operates as a generator as in the case of traveling, the battery 22 can be charged by the electric energy generated by the power generation operation of the motor.

도 3에서는 전륜(F)의 각 인휠 모터(18) 및 엔진(11)에 마운트 된 모터 제너레이터(12)를 개별 구동할 수 있는 인버터들을 도면부호 21로 지시된 하나의 인버터 시스템(Inverter System)으로 통합하여 도시하였다. In Fig. 3, inverters capable of individually driving the respective in-wheel motor 18 of the front wheel F and the motor generator 12 mounted on the engine 11 are connected to one inverter system indicated by reference numeral 21 Respectively.

도 4는 본 발명의 실시예에 따른 구동 시스템이 적용된 4WD 하이브리드 자동차의 주행 모드를 설명하기 위한 도면으로, (a)는 엔진(11)과 인휠 모터(18)로 차량을 구동하는 모드, 즉 엔진 동력과 인휠 모터의 동력으로 후륜(R)과 전륜(F)을 각각 구동시켜 차량이 주행하는 HEV 모드를 나타낸다.4A and 4B are diagrams for explaining a traveling mode of a 4WD hybrid vehicle to which a driving system according to an embodiment of the present invention is applied. FIG. 4A shows a mode for driving a vehicle by an engine 11 and an in- And shows the HEV mode in which the vehicle travels by driving the rear wheel R and the front wheel F respectively by the power and the power of the in-wheel motor.

또한, (b)는 차량의 제동시나 타행 주행시 인휠 모터(18)로 차량의 운동에너지를 회수하는 에너지 회생 모드를 나타내고, (c)는 인휠 모터(18)만으로 차량을 구동하는 EV 모드를 나타낸다.(B) shows an energy regeneration mode for recovering the kinetic energy of the vehicle by the in-wheel motor 18 when the vehicle is braking or traveling in a line, and (c) shows an EV mode for driving the vehicle only with the in-wheel motor 18.

먼저, (a)에 나타낸 바와 같이 HEV 모드에서는 차량 주행을 위해 차량의 구동원이 되는 엔진(11)과 인휠 모터(18)가 작동되는데, 인휠 모터(18)가 차량 주행시 엔진 출력을 보조하는 토크 어시스트 용도로 사용된다.First, as shown in (a), in the HEV mode, the engine 11 and the in-wheel motor 18, which are the driving sources of the vehicle, are operated for running the vehicle. In the in-wheel motor 18, It is used for the purpose.

이때, 엔진 동력이 후륜(R)으로 전달될 수 있도록 디커플러 또는 클러치 등의 동력단속수단(15)은 닫힘(결합 또는 접합)(closed) 상태가 되도록 제어되며, 이에 인휠 모터(18)의 동력으로 전륜(F)이 구동될 때 엔진 동력은 후륜(R)으로 전달되어 후륜(R)이 구동될 수 있게 된다.At this time, the power interrupting means 15 such as a decoupler or a clutch is controlled to be closed (coupled or closed) so that the engine power can be transmitted to the rear wheel R, The engine power is transmitted to the rear wheel R and the rear wheel R can be driven when the front wheel F is driven.

상기와 같은 HEV 모드에서 엔진(11)에 마운트 된 모터 제너레이터(12)는 발전 제어를 통해 엔진 토크 저감(Engine Torque Reduction)을 위해 사용될 수 있으며, 이때 모터 제너레이터(12)의 발전작동으로 생성되는 전기에너지가 배터리(22)에 저장되는 배터리 충전이 이루어진다.In the HEV mode, the motor generator 12 mounted on the engine 11 can be used for engine torque reduction through power generation control. In this case, the electric power generated by the power generation operation of the motor generator 12 Battery charging is performed in which energy is stored in the battery 22.

또한, 상기 모터 제너레이터(12)는 전륜(F)의 각 인휠 모터(18)와 마찬가지로 엔진(11)의 출력을 보조하는 토크 어시스트 용도로 사용될 수도 있다. The motor generator 12 may be used as a torque assist for assisting the output of the engine 11 like the in-wheel motor 18 of the front wheel F. [

다음으로, (b)에 나타낸 바와 같이 에너지 회생 모드에서는 전륜(F)의 인휠 모터(18)를 이용하여 차량의 운동에너지를 회수하는 에너지 회생이 수행되고, 각 인휠 모터(18)의 발전작동으로 생성되는 전기에너지에 의해 배터리(22)가 충전된다.Next, as shown in (b), in the energy regeneration mode, energy recovery is performed to recover the kinetic energy of the vehicle by using the in-wheel motor 18 of the front wheel F, The battery 22 is charged by the generated electric energy.

이때, 동력단속수단(15)을 오픈(분리)(open) 상태가 되도록 제어하여 엔진(11) 및 모터 제너레이터(12), 변속기(13)와 후륜(R) 사이의 동력 전달이 단절되도록 함으로써 전륜(F)의 인휠 모터(18)에 의한 회생제동량이 극대화되도록 한다.At this time, by controlling the power interrupting means 15 to be in the open state, power transmission between the engine 11, the motor generator 12, the transmission 13 and the rear wheel R is cut off, The regenerative braking amount by the in-wheel motor 18 of the engine F is maximized.

물론, 필요한 경우, 예를 들어 보다 큰 회생제동력을 얻고자 하는 경우 동력단속수단(15)을 닫힘 상태가 되도록 제어한 뒤 엔진(11)과 변속기(13) 사이의 모터 제너레이터(12)를 이용하여 후륜(R)을 통한 회생제동이 수행되도록 할 수 있다.Of course, if necessary, for example, in order to obtain a larger regenerative braking force, the power interrupting means 15 is controlled to be in the closed state, and then the motor generator 12 between the engine 11 and the transmission 13 is used The regenerative braking through the rear wheel R can be performed.

다음으로, (c)에 나타낸 바와 같이 EV 모드에서는 전륜(F)을 구동륜으로 사용하는데, 이때 동력단속수단(15)을 오픈 상태가 되도록 제어하여 엔진(11)과 후륜(R) 사이에 동력이 차단되도록 하고, 동시에 인휠 모터(18)로 전륜(F)을 구동시켜 차량이 주행되도록 한다.Next, as shown in (c), in the EV mode, the front wheel F is used as a drive wheel, and at this time, the power interrupting means 15 is controlled to be in the open state so that power is supplied between the engine 11 and the rear wheel R And at the same time, the front wheel F is driven by the in-wheel motor 18 so that the vehicle is driven.

이때, 엔진(11)을 작동시켜 엔진 동력이 모터 제너레이터(12)에 전달되도록 하는 동시에, 발전기로 작동되는 모터 제너레이터(12)에 의해 배터리(22)의 충전이 이루어지도록 하고, 더불어 배터리(22)에 충전된 전기에너지로 각 인휠 모터(18)를 구동시키는 직렬 모드의 주행이 이루어질 수 있다.At this time, the engine 11 is operated so that the engine power is transmitted to the motor generator 12, the battery 22 is charged by the motor generator 12 operated by the generator, The in-wheel motor 18 is driven by electric energy charged in the in-line mode.

이와 같이 하여, 본 발명의 구동 시스템에서는 엔진과 변속기 사이의 클러치를 삭제하여 클러치로 인한 엔진과 변속기 사이의 구동 손실 발생을 방지할 수 있고, 엔진과 변속기 사이의 모터 제너레이터를 이용하여 기존의 HSG를 대체할 수 있으므로 부품 수 축소, 원가 절감 및 중량 저감을 달성할 수 있게 된다.In this manner, in the drive system of the present invention, the clutch between the engine and the transmission can be eliminated to prevent the occurrence of drive loss between the engine and the transmission due to the clutch, and the existing HSG can be prevented by using the motor generator between the engine and the transmission It is possible to reduce the number of components, reduce cost, and reduce weight.

또한, 엔진과 전륜의 인휠 모터로 차량을 구동하는 4WD 방식의 HEV 모드 주행, 그리고 엔진과 변속기 사이의 모터 제너레이터를 발전기로 사용하면서 전륜의 인휠 모터로 차량을 구동하는 직렬 모드(EV 모드) 주행이 가능함에 따라, 저용량 HSG를 사용하는 종래의 전륜 TMED 시스템이 가지는 고질적인 문제점인 등판 주행 및 도심 정체 주행시 연비 저하의 문제점이 해결될 수 있게 된다. In addition, the 4WD HEV mode driving the vehicle with the engine and the front wheel in-wheel motor, and the serial mode (EV mode) driving the vehicle with the front wheel in-wheel motor while using the motor generator between the engine and the transmission as the generator. As a result, it is possible to solve the problems of the backlash driving and the fuel consumption deterioration when the vehicle is running in the center of the city, which is a chronic problem of the conventional front wheel TMED system using the low capacity HSG.

또한, 출력에 제한이 있는 모터를 사용하여 전륜을 구동하고 출력에 여유가 있는 엔진으로 후륜을 구동할 수 있으므로 선회 및 등판 주행시 후륜에 더 큰 토크가 인가되도록 할 수 있고, 이상적인 비율에 가까운 전, 후륜 토크 분배가 구현될 수 있다.In addition, since the rear wheel can be driven by an engine having a limited output, by driving a front wheel using a motor having a limited output, a larger torque can be applied to the rear wheel at the time of turning and backing, Rear wheel torque distribution can be implemented.

특히, 전륜의 인휠 모터 장착으로 차량의 동력 성능이 개선될 수 있는데, 예컨대 종래에 비해 높은 구배의 눈길 등판로에서도 등판이 가능해지는 등 차량의 등판 성능이 향상될 수 있고, 추가적인 인휠 모터 장착으로 제로백 성능이 개선될 수 있으며, 전륜의 인휠 모터를 이용하여 토크 벡터링(torque vectoring) 기능을 구현하는 것 또한 가능하다.Particularly, the power performance of the vehicle can be improved by installing an in-wheel motor of the front wheel. For example, it is possible to improve the back-up performance of the vehicle, Performance can be improved, and it is also possible to implement a torque vectoring function using an in-wheel motor of the front wheel.

또한, 구동 손실 및 변속이 없는 인휠 모터를 전륜에 설치하여 회생제동 효율의 극대화가 가능해지는바, 종래의 TMED 시스템에 비해 회생제동 효율을 크게 개선할 수 있게 된다.In addition, an in-wheel motor having no drive loss and no shifting can be provided on the front wheels to maximize the regenerative braking efficiency, which makes it possible to significantly improve the regenerative braking efficiency as compared with the conventional TMED system.

또한, 본 발명의 구동 시스템에서는 후륜으로의 동력 전달을 차단하는 디커플러와 같은 동력단속수단을 적용하여 EV 모드 주행시 동력단속수단을 오픈함으로써 프로펠러축의 회전을 방지할 수 있고, 이에 구동 손실이 최소화되는 EV 모드를 구현할 수 있게 된다.Further, in the drive system of the present invention, the power interrupting means such as a decoupler which interrupts the power transmission to the rear wheels is applied to open the power interrupting means during EV mode travel, thereby preventing rotation of the propeller shaft, It is possible to implement the EV mode.
