본 발명은 소프트 타입 하이브리드 차량에 관한 것으로, 보다 상세하게는 초기 구동 시 EV 모드(Electric Vehicle Mode)를 구현할 수 있도록 한 소프트 타입 하이브리드 차량의 이브이 모드 구현장치 및 그 구현 방법에 관한 것이다.The present invention relates to a soft type hybrid vehicle, and more particularly, to an apparatus and a method for implementing the EVE mode of a soft type hybrid vehicle to implement an electric vehicle mode during initial driving.

일반적으로 내연기관 자동차에 의한 대기 오염을 줄이기 위한 환경 친화적인 하이브리드(Hybrid) 자동차는 내연기관인 엔진과 전기 모터를 사용하는 방식으로, 각각의 주행상황에 대응하여 내연기관의 연비가 가장 높게 운전되도록 제어되고 제동 시와 감속 시에 모터가 발전기로 작동하여 회생 제동 에너지를 전기 에너지로 회수하여 배터리를 충전시켜, 가솔린 엔진에 비해 연비 향상을 이룰 수 있으며 시내 구간에서 엔진을 작동하지 않은 상태에서 배터리의 전압만으로 주행할 수 있게 된다.In general, an environmentally friendly hybrid vehicle for reducing air pollution by an internal combustion engine vehicle uses an engine and an electric motor, which are internal combustion engines, so that the fuel economy of the internal combustion engine is driven to the highest in response to each driving situation. When braking and decelerating, the motor operates as a generator to recover the regenerative braking energy as electrical energy to charge the battery, resulting in improved fuel economy compared to gasoline engines. You can drive alone.

이러한, 하이브리드 차량은 동력원인 내연기관 엔진과 별도의 동력원인 모터를 이중으로 채용해, 엔진의 운전영역을 최고 효율점에 놓고 가속이나 감속 시 필요한 동력은 모터를 통해 부과하여 엔진의 부담을 줄임으로서, 연비와 배기가스를 줄일 수 있는 하이브리드용 동력시스템(Hybrid electric vehicle)이 사용되며, 이는 통상적으로 엔진과 변속기(Transmission)사이에, 내연기관의 운전영역을 최고 효율점에 놓고 가속이나 감속 시 필요한 동력을 부과하여 엔진의 부담을 줄이기 위한 전기모터가 장착되며, 모터와 엔진 사이에는 엔진과 모터간 회전을 일치하기 위한 이중 클러치가 구비되어진다.The hybrid vehicle employs a dual-use internal combustion engine engine and a separate power source motor so that the operating range of the engine is at the highest efficiency point, and the power required for acceleration or deceleration is imposed through the motor to reduce the burden on the engine. In addition, a hybrid electric vehicle is used to reduce fuel consumption and emissions, which is usually required between acceleration and deceleration between the engine and the transmission with the operating area of the internal combustion engine at the highest efficiency point. An electric motor is mounted to reduce the burden on the engine by applying power, and a double clutch is provided between the motor and the engine to match rotation between the engine and the motor.

이때, 하이브리드 차량은 통상 EV(electric vehicle)모드인 모터의 회전력만 을 이용하는 순수 전기자동차 모드나 또는, HEV(hybrid electric vehicle)모드인 엔진의 회전력을 주동력으로 하고, 상기 모터의 회전력을 보조 동력으로 이용하는 모드로 작동되어진다.At this time, the hybrid vehicle is a pure electric vehicle mode using only the rotational force of the motor in the EV (electric vehicle) mode, or the rotational force of the engine in the HEV (hybrid electric vehicle) mode as the main power, the rotational power of the motor is the auxiliary power It is operated in the mode used.

또한, 하이브리드 차량은 통상 모터의 구동 출력이 약 50KW인 하드(Hard)타입 하이브리드 구조와, 엔진의 출력을 보조하는 모터를 변속기(A/T, Auto Transmission)와 토크컨버터(T/CON, Torque Convertor)사이에 삽입함과 동시에 모터와 엔진과의 연결을 결합/차단 할 수 있도록 엔진클러치를 삽입해, 모터의 구동 출력이 약 13KW로 상대적으로 작은 소프트(Soft)타입 하이브리드 구조로 대별될 수 있게 된다.In addition, a hybrid vehicle has a hard type hybrid structure in which a drive output of a motor is generally about 50 kW, and a motor that assists the output of the engine includes a transmission (A / T, auto transmission) and a torque converter (T / CON, torque converter). ), And the engine clutch is inserted so that the connection between the motor and the engine can be combined and blocked, and the driving output of the motor can be roughly classified into a soft type hybrid structure having a relatively small power of about 13 kW. .

이에 더해, 이와 같은 하이브리드 차량 중 소프트(Soft)타입의 경우에는 통상 엔진의 시동 및 구도모터와의 속도 동기화를 ISG (Integrated Starter Generator)를 사용하게 되는데, 이러한 ISG의 경우 일반차량에서 사용하고 있는 스타터(Starter)모터와는 달리, 벨트-풀리를 사용하여 연결하며 엔진속도와 구동모터의 속도 동기화를 목적으로 사용하기 때문에 감속하여 엔진을 시동할 수는 없게 된다.In addition, in the soft type of such hybrid vehicles, ISG (Integrated Starter Generator) is usually used for starting the engine and synchronizing the speed with the old motor.In the case of such ISG, the starter used in the general vehicle is used. Unlike a motor, it is not possible to start the engine by decelerating because it is connected using a belt-pulley and used for the purpose of synchronizing the engine speed with the driving motor.

그러나, 소프트 타입 하이브리드 차량은 모터의 구동 출력이 상대적으로 작은 관계로 EV(electric vehicle)모드 시, 엔진이 아닌 순수한 모터에 의해서 차량이 출발하게 되므로 초기에 변속기(A/T)에서 1속을 유지하기 위한 유압이 변속기내 클러치 쪽에 반드시 공급되어야 함에 따라, 이를 위해 별도의 외장형 전동 식 오일 펌프를 구동하여 D 변속단(Range)에서 발진 직전까지의 변속기의 유압을 유지해주 게 된다.However, the soft type hybrid vehicle maintains the first speed in the transmission (A / T) initially because the vehicle is started by a pure motor instead of the engine in the electric vehicle (EV) mode because the driving output of the motor is relatively small. Since the hydraulic pressure must be supplied to the clutch in the transmission, a separate external electric oil pump is driven to maintain the hydraulic pressure of the transmission from the D shift range to just before the start.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 소프트 타입 하이브리드 차량의 초기 구동을 위한 EV 모드 시, 오일펌프를 구동모터에 연동해 작동시켜 변속기에서 요구되는 1속 유압을 공급하도록 함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and in the EV mode for initial driving of the soft type hybrid vehicle, the oil pump is operated in conjunction with the drive motor to supply the first speed hydraulic pressure required by the transmission. There is a purpose.

또한, 본 발명은 소프트 타입 하이브리드 차량의 초기 구동을 위한 EV 모드 시, 변속기에서 요구되는 유압을 공급하는 오일펌프를 구동 모터의 축상에 함께 장착할 수 있도록 함에 그 목적이 있다. In addition, an object of the present invention is to enable the oil pump for supplying the hydraulic pressure required in the transmission in the EV mode for the initial driving of the soft type hybrid vehicle can be mounted together on the shaft of the drive motor.

상기와 같은 목적을 달성하기 위한 본 발명은, 소프트 타입 하이브리드 차량의 이브이 모드 구현장치가 EV 모드 시 배터리의 전원을 통해 구동되어 초기 출발을 위한 구동력을 발생하는 구동모터와; The present invention for achieving the above object, the drive motor for generating a driving force for the initial start is driven by the power supply of the battery when the EVE mode implementation apparatus of the soft type hybrid vehicle;

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 소프트 타입 하이브리드 차량의 EV 모드 구현장치의 구성도를 도시한 것인바, 본 발명에 따른 소프트 타입 하이브리드 차량은 EV 모드 시 배터리의 전원을 통해 구동되어 초기 출발을 위한 구동력을 발생하는 구동모터(6)와, EV 모드 해제 시 동력 전환을 위해 ISG(2)를 통해 구동모터(6)와 동기화를 이루면서 동력을 발생하는 엔진(1), 토크컨버터(4)가 장착된 축 상에 구동모터(6)와 엔진클러치(5)를 구비하면서 변속단에 따른 변속을 수행하는 변속기(3) 및 EV 모드 초기 발진 시 변속기를 1속 상태로 유지하는 제어수단으로 이루어진다.1 is a block diagram of an apparatus for implementing an EV mode of a soft type hybrid vehicle according to the present invention. The soft type hybrid vehicle according to the present invention is driven through a power source of a battery in an EV mode to provide a driving force for an initial start. A shaft on which the engine 1 and the torque converter 4 which generate power while synchronizing with the driving motor 6 through the ISG 2 for switching power when the EV mode is released and the EV mode release are generated. A transmission motor 3 and an engine clutch 5 are provided on the transmission 3 for shifting according to the shift stage, and control means for maintaining the transmission at the 1-speed state when the EV mode is initially started.

여기서, 상기 제어수단은 엔진(1)으로 이어지는 변속기(3)의 축 상에서 구동모터(6)의 전단에서 축에 결합된 오일펌프(9)와, 변속레버위치센서(12)를 통한 변속 단 정보와 브레이크페달위치센서(13)를 통한 페달 조작 정보를 입력받아 초기 발진 시 EV 모드로 실행할지 HEV모드로 실행할지 판단하는 HCU(11) 및 구동모터(6)의 구동을 통해 함께 구동되는 오일펌프(9)로부터 변속기(3)로 공급된 유압을 시동 후 엔진클러치(5)가 엔게이지(Engage)되도록 밸브바디(8)의 유압 경로를 제어하는TCU(10)로 구성되어진다.Here, the control means is an oil pump 9 coupled to the shaft at the front end of the drive motor 6 on the shaft of the transmission 3 leading to the engine 1 and the shift stage information through the shift lever position sensor 12. And an oil pump driven together by driving the HCU 11 and the driving motor 6 to determine whether to run in the EV mode or the HEV mode at the initial start by receiving the pedal operation information through the brake pedal position sensor 13. It consists of the TCU 10 which controls the hydraulic path of the valve body 8 so that the engine clutch 5 may be Engaged after starting the hydraulic pressure supplied from the 9 to the transmission 3.

이때, 상기 HCU(11)는 ISG(2)와 구동모터(5)를 구동시키며, 상기 ISG(2)와 구동모터(5)는 인버터(7,Inverter)를 거쳐 작동됨은 물론이다. In this case, the HCU 11 drives the ISG 2 and the driving motor 5, and the ISG 2 and the driving motor 5 are operated through an inverter 7.

또한, 상기 밸브바디(8)는 오일펌프(9)와 엔진클러치(6)간 유압 흐름 경로를 형성함과 더불어, 변속기(3)로 공급되는 유압 흐름을 제어하는 TCU(10)를 통해 엔진클러치(6)쪽으로 유압을 공급하도록 제어된다.In addition, the valve body 8 forms the hydraulic flow path between the oil pump 9 and the engine clutch 6, and the engine clutch through the TCU 10 for controlling the hydraulic flow supplied to the transmission 3. It is controlled to supply hydraulic pressure toward (6).

이하 본 발명의 작동을 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 소프트 타입 하이브리드 차량의 초기 발진 시, HCU(11)가 EV 모드 에서 초기 시동 후 발진 시 완료까지 변속기(3)를 1속 상태로 유지하면서 EV 모드를 통한 원활한 차량의 초기 발진이 이루어지도록 제어를 수행하게 된다.In the present invention, when the initial start-up of the soft type hybrid vehicle, the HCU (11) so that the initial start of the vehicle smoothly through the EV mode while maintaining the transmission 3 in the 1-speed state until completion at the start-up after the initial start in the EV mode Control will be performed.

즉, 도 2에 도시된 바와 같이 HCU(11)는 브레이크페달위치센서(13)를 통한 페달이 조작된 정보를 입력받은 상태에서, 변속레버위치센서(12)를 통해 변속레버의 변속 단 위치에 대한 정보를 이용해 변속단이 P,N,D에 위치되었는가를 판단하게 된다.That is, as shown in FIG. 2, the HCU 11 receives the operation information of the pedal through the brake pedal position sensor 13, and at the shift end position of the shift lever through the shift lever position sensor 12. Information is used to determine whether the shift stage is located at P, N, or D.

이어, 브레이크 페달이 조작된 상태에서 변속단이 P,N,D에 위치된 상태이면 HCU(11)는, 차량이 발진하려는 상황으로 판단해 EV 모드의 실행을 준비하게 된다.Subsequently, if the shift stages are positioned at P, N, and D while the brake pedal is operated, the HCU 11 determines that the vehicle is to start and prepares to execute the EV mode.

이후, 상기 HCU(11)는 엔진클러치(5)가 해제 상태임을 인식한 다음 인버터(7)를 거쳐 구동모터(6)를 구동시켜 줌과 더불어 TCU(10)로 제어신호를 전송해, 상기 TCU(10)가 구동모터(6)와 함께 구동되는 오일펌프(9)에서 발생된 유압이 밸브바디(8)로 공급되어 변속기(3)가 1속 상태를 유지하도록 한다.Thereafter, the HCU 11 recognizes that the engine clutch 5 is in a released state, drives the driving motor 6 through the inverter 7, and transmits a control signal to the TCU 10. The hydraulic pressure generated by the oil pump 9 driven together with the drive motor 6 is supplied to the valve body 8 so that the transmission 3 maintains the first speed state.

이어, 상기 HCU(11)는 변속레버위치센서(12)를 통해 변속레버의 변속 단 위치가 D이면서 동시에, 가속페달위치센서를 통해 가속 페달이 조작되었는지를 인식한 후, D 변속위치와 가속페달 조작이 이루어진 상태에서 TCU(10)를 통해 밸브바디(8)의 유압을 엔진클러치(5)로 공급하게 된다.Subsequently, the HCU 11 recognizes whether the shift stage position of the shift lever is D through the shift lever position sensor 12, and at the same time recognizes whether the accelerator pedal is operated through the accelerator pedal position sensor. The hydraulic pressure of the valve body 8 is supplied to the engine clutch 5 through the TCU 10 while the operation is made.

이와 같이, 상기 엔진클러치(5)로 공급된 유압을 통해 엔게이지(Engage)되면서 엔진과 맞물린 상태에서 차량이 출발되면, 상기 HCU(11)는 엔진(1)을 통한 동력을 주 동력으로 전환시키도록 ISG(2)를 통해 엔진(1)을 구동시켜 HEV 모드로 차량을 주행시켜 주게 된다.As such, when the vehicle starts while being engaged with the engine while being engaged with the engine through the hydraulic pressure supplied to the engine clutch 5, the HCU 11 converts the power through the engine 1 into the main power. The engine 1 is driven through the ISG 2 to drive the vehicle in the HEV mode.

이상 설명한 바와 같이 본 발명에 의하면, 차량의 초기 시동 모드인 EV 모드 시 변속기를 1속 상태로 유지하는 유압을 공급하는 오일펌프가 구동모터를 통해 구동되도록 해, 별도의 외장형 오일펌프를 사용할 때에 비해 제어 로직이 간단해지면서 엔진룸의 공간을 보다 최적화할 수 있는 효과가 있게 된다.As described above, according to the present invention, the oil pump for supplying the hydraulic pressure that maintains the transmission at the first speed in the EV mode, which is the initial starting mode of the vehicle, is driven through the drive motor, so that a separate external oil pump is used. The simplicity of the control logic has the effect of further optimizing the space in the engine room.
