Description

하이브리드 차량의 제어방법 {METHOD FOR CONTROLLING OF HYBRID VEHICLE}[0001] METHOD FOR CONTROLLING OF HYBRID VEHICLE [0002]

본 발명은 EV모드로 정차 중인 상황에서 난방장치가 온(ON) 조작될 경우에 난방효과를 증가시키면서도 엔진 동력 에너지를 낭비하는 것을 줄이는 TMED 타입 하이브리드 차량의 제어방법에 관한 것이다.The present invention relates to a control method of a TMED type hybrid vehicle that reduces the waste of engine power energy while increasing the heating effect when the heating device is turned on in a state where the vehicle is stopped in the EV mode.

하이브리드 차량은 일종의 친환경 차량으로서 엔진과 모터를 동력원으로 하는 다양한 동력전달장치를 구성할 수 있으며, 엔진클러치가 구비되는 동력전달장치의 경우 엔진 동력의 전달을 위해 엔진을 기동하고 엔진클러치의 양단 속도를 동기화하여 엔진 동력을 차륜으로 전달할 수 있도록 마련된다. 이때, 통상 운전자의 요구를 바탕으로 엔진 동력이 필요한 상황에 엔진을 기동하게 된다.The hybrid vehicle is an eco-friendly vehicle, which can constitute a variety of power transmission devices using an engine and a motor as power sources. In the case of a power transmission device having an engine clutch, the hybrid vehicle is operated to start the engine for transmitting the engine power, So that the engine power can be transmitted to the wheels in synchronization with each other. At this time, the engine is started in a situation where engine power is required based on the demand of the driver.

한편, 하이브리드 차량의 실내 공조를 위한 제어는 쿨링 제어 및 히팅 제어로 구분된다.On the other hand, the control for the indoor air conditioning of the hybrid vehicle is classified into the cooling control and the heating control.

하이브리드 차량의 공조를 위한 제어, 즉 쿨링 제어와 히팅 제어는 그 방법에 있어서 차이가 있는데, 실내 냉방을 위한 쿨링 제어는 전동식 컴프레셔가 장착된 에어컨이 배터리를 에너지원으로 구동하여 이루어지고, 실내 난방을 위한 히팅 제어는 엔진의 구동열을 에너지원으로 사용하여 이루어진다.The control for air conditioning of the hybrid vehicle, that is, the cooling control and the heating control are different in the method. The cooling control for the indoor cooling is performed by the air conditioner equipped with the electric compressor driving the battery as the energy source, Is performed by using the driving heat of the engine as an energy source.

상기 히팅 제어에 의해 승온된 엔진 냉각수가 공조장치의 히터코어를 통과하여 실내로 유입되는 외기와 열교환함으로써 실내 난방이 이루어진다.The engine cooling water heated by the heating control passes through the heater core of the air conditioner and performs heat exchange with the outside air flowing into the room, thereby heating the room.

이러한 히팅 제어의 경우, 배터리 충전상태나 차량의 주행패턴과 상관없이 실내 온도를 맞추기 위한 조건에 의해 엔진을 오프 상태에서 온 상태로 제어하게 된다. 이때, 엔진은 단순히 구동열을 발생시키기 위해 공회전하게 마련되는바, 엔진 동력이 낭비된다는 문제점이 발생한다.In the case of such heating control, the engine is controlled from the off state to the on state by the conditions for adjusting the indoor temperature regardless of the battery charging state or the running pattern of the vehicle. At this time, since the engine is simply idled to generate driving heat, the engine power is wasted.

상기의 배경기술로서 설명된 사항들은 본 발명의 배경에 대한 이해 증진을 위한 것일 뿐, 이 기술분야에서 통상의 지식을 가진자에게 이미 알려진 종래기술에 해당함을 인정하는 것으로 받아들여져서는 안 될 것이다.It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

상기 확인단계 수행결과, 차량이 엔진 오프(OFF) 상태로 정차 중이면서 난방장치가 온(ON)일 경우, 상기 제1비교단계를 수행하기 전에 상기 제어부가 하이브리드 차량의 시동 후 주행여부를 판단하는 판단단계; 및 상기 판단단계 수행결과, 차량이 시동 후 주행이 이루어진 경우, 상기 제어부가 냉각수온을 상기 제1설정온도보다 높게 설정된 제2설정온도와 비교하는 제2비교단계;를 더 포함하고, 상기 제2비교단계 수행결과, 냉각수온이 제2설정온도 이하이면 상기 제어부는 상기 제어단계를 수행하는 것을 특징으로 할 수 있다.If it is determined that the vehicle is in the engine OFF state and the heating device is ON as a result of the checking step, the controller determines whether the hybrid vehicle is running after starting the hybrid vehicle before performing the first comparing step Determining; And a second comparing step of comparing the cooling water temperature with a second set temperature which is set higher than the first set temperature when the vehicle is running after the start of the vehicle as a result of the determining step, And the control unit performs the control step if the cooling water temperature is equal to or lower than the second set temperature as a result of the comparison step.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예에 따른 하이브리드 차량의 제어방법에 대하여 살펴본다.Hereinafter, a method of controlling a hybrid vehicle according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명의 일 실시예에 따른 하이브리드 차량의 제어방법을 도시한 순서도이고, 도 2는 본 발명의 일 실시예에 따른 하이브리드 차량의 제어장치를 간략히 도시한 도면이다.FIG. 1 is a flowchart showing a control method of a hybrid vehicle according to an embodiment of the present invention, and FIG. 2 is a view showing a control device of a hybrid vehicle according to an embodiment of the present invention.

도 1 내지 도 2를 참조하면 엔진(10)과 모터(30) 사이에 엔진클러치(20)가 구비된 TMED(Transmission Mounted Electric Device) 타입의 하이브리드 차량의 제어방법에 있어서, 본 발명은 제어부(50)가 하이브리드 차량이 엔진(10) 오프(OFF)된 상태로 정차 중이면서 난방장치(미도시)가 온(ON) 상태인지 확인하는 확인단계(S100); 상기 확인단계(S100) 수행결과, 차량이 엔진(10) 오프(OFF) 상태로 정차 중이면서 난방장치가 온(ON)일 경우, 상기 제어부(50)가 외기온을 제1설정온도와 비교하는 제1비교단계(S120); 및 상기 제1비교단계(S120) 수행결과, 외기온이 제1설정온도 이하일 경우, 상기 제어부(50)가 엔진클러치(20)를 결합하고, 엔진(10)을 온(ON) 제어하는 제어단계(S140);를 포함할 수 있다.1 to 2, a control method of a TMED (Transmission Mounted Electric Device) type hybrid vehicle in which an engine clutch 20 is provided between an engine 10 and a motor 30, (S100) for confirming whether the hybrid vehicle is in the stopped state while the engine 10 is turned off and the heating device (not shown) is in the ON state; As a result of the checking step S100, when the vehicle is stopped in the OFF state of the engine 10 and the heating device is ON, the control unit 50 determines whether the outdoor temperature is higher than the first set temperature 1 comparison step S120; And a control step of controlling the engine 10 by engaging the engine clutch 20 when the outside air temperature is equal to or lower than the first set temperature as a result of the first comparison step S120 S140).

일반적으로 TMED 타입의 하이브리드 차량은 도 2에 도시된 바와 같이 엔진(10), 엔진클러치(20), 모터(30), 변속기(40), 차동장치, 차륜 순으로 연결되는 파워트레인 구조를 가지도록 마련된다. 즉, 엔진(10)과 모터(30) 사이의 엔진클러치(20)는 체결/해제 제어됨으로써, 차량의 주행모드를 EV모드와 HEV모드로 절환하는 역할을 수행한다.In general, a hybrid vehicle of the TMED type has a power train structure connected in the order of the engine 10, the engine clutch 20, the motor 30, the transmission 40, the differential, . That is, the engine clutch 20 between the engine 10 and the motor 30 performs engagement / release control, thereby switching the running mode of the vehicle between the EV mode and the HEV mode.

주로 차량의 주행모드가 EV(Electric Vehicle)모드이면, 엔진(10) 구동에 의한 소음발생 및 연비저하 현상을 최소화하기 위해 상기 엔진(10)은 오프(OFF)된 상태를 유지한다. The engine 10 is kept in an OFF state in order to minimize the generation of noise due to the driving of the engine 10 and the deterioration of the fuel consumption rate when the driving mode of the vehicle is an EV (Electric Vehicle) mode.

하지만, 만약 EV모드 중 승객에 의해 난방장치(미도시)가 온(ON) 제어되면, 엔진(10)이 오프(OFF) 상태이기 때문에 승객이 요구하는 난방온도를 구현하기에 어려움이 발생한다. 이는 엔진(10)이 오프(OFF) 상태일 때, 엔진냉각수 온도가 저하되는데, 상기 난방장치가 엔진(10) 냉각수를 이용하여 차량 난방을 수행하기 때문이다.However, if the heating device (not shown) is controlled by the passenger during the EV mode, since the engine 10 is in the OFF state, it is difficult to realize the heating temperature required by the passenger. This is because, when the engine 10 is in the OFF state, the engine coolant temperature is lowered because the heating apparatus performs the vehicle heating using the engine 10 coolant.

따라서, 본 발명에서 제어부(50)는 하이브리드 차량의 시동이 켜진 상태에서, 차량의 주행모드가 EV(Electric Vehicle)모드이고, 정차 중이며, 승객에 의해 난방장치가 온(ON)된 상태일 경우에 외기온을 제1설정온도와 비교하고, 외기온이 제1설정온도 이하일 경우에 정상적인 난방이 이루어질 수 있도록 엔진(10)을 온(ON) 제어하는 것을 특징으로 한다.Accordingly, in the present invention, when the hybrid vehicle is in the ON state, the traveling mode of the hybrid vehicle is the EV (Electric Vehicle) mode, the vehicle is stationary, and the heating device is ON by the passenger The outdoor temperature is compared with the first set temperature, and the engine 10 is controlled to be turned on so that normal heating can be performed when the outdoor temperature is equal to or lower than the first set temperature.

상기 제1설정온도는 차량이 극저온 상황인지 판단하기 위해 설정된 값으로 예컨대 -30℃와 같이 극저온의 온도로 설정될 수 있다. 즉, 제어부(50)는 차량이 시동된 직후 초기 주행이 이루어지지 않은 상태에서 정차 중일 경우, 차량의 극저온 상황을 극복하면서 난방장치를 통한 난방 요구를 충족시키기 위해, 엔진(10) 및 엔진클러치(20)를 동작시키도록 제어한다.The first set temperature may be a value set to determine whether the vehicle is in a cryogenic temperature, and may be set to a cryogenic temperature, for example, -30 ° C. That is, when the vehicle is stopped while the vehicle is not in the initial traveling state immediately after the vehicle is started, the control unit 50 controls the engine 10 and the engine clutch (not shown) so as to satisfy the heating demand through the heating apparatus while overcoming the cryogenic condition of the vehicle 20 are operated.

특히, 본 발명은 엔진(10)을 온(ON) 제어하면서 엔진클러치(20)도 결합함으로써, 엔진(10) 동력이 난방장치 승온을 위해서만 공회전하여 동력 에너지가 낭비되는 상황을 방지한다. 즉, 엔진클러치(20)가 결합되면, 공회전하는 엔진(10)의 동력이 모터(30)로 전달되고, 모터(30)와 연결된 배터리(35)가 회전하면서 배터리 충전이 이루어진다.Particularly, the present invention prevents the situation where the power of the engine 10 is idling only for raising the temperature of the heating device and the power energy is wasted, by coupling the engine clutch 20 while controlling the engine 10 to be ON. That is, when the engine clutch 20 is engaged, the power of the idling engine 10 is transmitted to the motor 30, and the battery 35 connected to the motor 30 is rotated to charge the battery.

여기서, 하이브리드 차량은 정차 중인 상황이기 때문에 변속기(40) 측의 클러치가 모두 해제된 상태일 것이고, 그에 따라 엔진클러치(20)를 결합하더라도 엔진 동력이 차륜으로 전달되지 않아 EV모드가 강제적으로 종료되는 것을 방지할 수 있다. 즉, 제어부(50)는 하이브리드 차량이 정차 중일 경우에만 엔진클러치(20)를 결합하기 때문에, EV모드로 차량이 주행 중일 때에 엔진클러치(20)가 불필요하게 결합되어 EV모드가 종료되는 것을 막을 수 있다.Here, since the hybrid vehicle is in a stopped state, the clutch on the side of the transmission 40 is all released. Accordingly, even when the engine clutch 20 is engaged, the engine power is not transmitted to the wheels and the EV mode is forcibly terminated Can be prevented. That is, since the control unit 50 engages the engine clutch 20 only when the hybrid vehicle is stopped, the engine clutch 20 is unnecessarily engaged when the vehicle is running in the EV mode, have.

상기 제어부(50)는 엔진(10) 및 엔진(10)을 온/오프(ON/OFF)하는 HSG(Hybrid Start Generator,15)를 제어하도록 마련된 ECU(Engine Control Unit)일 수 있다. 본 발명에서 ECU는 엔진클러치(20)를 체결제어하기 위해 HCU(Hybrid Control Unit)에 전동유압식 액츄에이터(25)를 작동시키도록 제어신호를 출력하고, 제어신호에 따라 HCU는 LCU(Local Control Unit)에 동작신호를 출력하여 엔진클러치(20)를 작동시키도록 유도한다. The control unit 50 may be an ECU (Engine Control Unit) configured to control the engine 10 and the HSG (Hybrid Start Generator) 15 for turning the engine 10 on and off. In the present invention, the ECU outputs a control signal to actuate the hydraulic hydraulic actuator 25 to the HCU (Hybrid Control Unit) so as to control the engagement of the engine clutch 20. The HCU is connected to an LCU (Local Control Unit) So that the engine clutch 20 is operated.

상기 제어부(50)는 별도의 차속센서나, HCU와의 통신을 통해서 차량이 정차중인지, 난방장치가 동작 중인지 확인할 수 있고, 온도센서를 통해 외기온 데이터를 수신할 수 있다.The controller 50 can confirm whether the vehicle is stopped or heating by operating a separate vehicle speed sensor or communication with the HCU, and can receive outdoor temperature data through the temperature sensor.

본 발명의 상기 제어단계(S130)에서, 상기 제어부(50)는 엔진클러치(20)의 결합을 완료한 후, 엔진(10)을 온(ON) 제어할 수 있다. 즉, 엔진(10)을 구동시키기 전에 엔진클러치(20)를 모터(30)와 미리 연결함으로써, 엔진(10) 구동 중 모터(30)와의 결합으로 인해 충격이 발생하는 것을 방지할 수 있다.In the control step S130 of the present invention, the controller 50 may control the engine 10 to be ON after the engagement of the engine clutch 20 is completed. That is, by connecting the engine clutch 20 to the motor 30 in advance before driving the engine 10, it is possible to prevent the occurrence of an impact due to the engagement with the motor 30 during driving of the engine 10.

아울러, 본 발명에서 상기 확인단계(S100) 수행결과, 차량이 엔진(10) 오프(OFF) 상태로 정차 중이면서 난방장치가 온(ON)일 경우, 상기 제1비교단계(S120)를 수행하기 전에 상기 제어부(50)가 하이브리드 차량의 시동 후 주행여부를 판단하는 판단단계(S110); 및 상기 판단단계(S110) 수행결과, 차량이 시동 후 주행이 이루어진 경우, 상기 제어부(50)가 냉각수온을 상기 제1설정온도보다 높게 설정된 제2설정온도와 비교하는 제2비교단계(S130);를 더 포함하고, 상기 제2비교단계(S130) 수행결과, 냉각수온이 제2설정온도 이하이면 상기 제어부(50)는 상기 제어단계(S140)를 수행할 수 있다.If it is determined that the vehicle is stopped while the engine 10 is in the OFF state and the heating apparatus is turned on as a result of the checking step S100 of the present invention, (S110) in which the control unit (50) determines whether the hybrid vehicle is running after starting the hybrid vehicle; And a second comparing step (S130) of comparing the cooling water temperature with a second set temperature which is set higher than the first set temperature when the vehicle is running after the start of the vehicle as a result of the determining step (S110) The controller 50 may perform the control step S140 if the cooling water temperature is lower than the second set temperature as a result of the second comparison step S130.

즉, 제어부(50)는 차량이 시동된 후 초기 주행이 수행되어, EV모드로 차량이 주행되다가 정차한 상황이라면, 외기온뿐만 아니라 엔진(10)의 냉각수온을 기반으로 하여 엔진(10) 및 엔진클러치(20)의 동작여부를 판단한다.That is, if the vehicle is running in the EV mode and the vehicle is stopped, the control unit 50 controls the engine 10 and the engine 10 based on the cooling water temperature of the engine 10 as well as the outside temperature, It is determined whether or not the clutch 20 is operated.

만약, 냉각수온이 설정된 제2설정온도 이하일 경우에는 난방장치를 통해 승객이 요구하는 온도를 충족할 수 없다고 판단하여, 제어부(50)는 엔진클러치(20)를 결합한 후 엔진(10)을 온(ON) 제어한다.If the cooling water temperature is equal to or lower than the set second set temperature, the control unit 50 determines that the temperature required by the passenger can not be satisfied through the heating unit. Then, the controller 50 turns on the engine 10 after coupling the engine clutch 20 ON).

상기 제2설정온도는 난방장치의 목표온도와 비례하게 산출되는 값으로써, 냉각수온이 난방장치를 통해 목표온도를 구현할 수 있을 정도 온도인지 판별할 수 있는 기준값이라 할 수 있다. 이는 다수의 실험을 통해서 산출될 수 있고, 차량 또는 설계자에 따라 다양하게 설정될 수 있는바, 특정한 수치로 한정될 수 없다. 다만, 상기 제2설정온도는 극저온 상황을 판별하는 제1설정온도보다는 높은 값으로 설정되는 것이 바람직할 것이다.The second set temperature is a value calculated in proportion to the target temperature of the heating device, and may be a reference value that can determine whether the cooling water temperature is a temperature at which the target temperature can be realized through the heating device. This can be calculated through a number of experiments, and can be variously set depending on the vehicle or the designer, and can not be limited to a specific value. However, it is preferable that the second set temperature is set to a value higher than a first set temperature for discriminating a cryogenic condition.

한편, 상기 판단단계(S110) 수행결과, 차량이 시동 후 주행이 이루어지지 않은 경우라면, 상기 제어부(50)는 상기 제1비교단계(S120) 만을 수행할 수 있다.On the other hand, if it is determined that the vehicle has not been driven since the start of the vehicle as a result of the determining step S110, the controller 50 may perform only the first comparing step S120.

즉, 본 발명에서 제어부(50)는 차량이 초기 주행이 수행되지 전보다 후인 EV모드 주행 중인 상황에서 난방장치가 동작할 경우에 보다 적극적으로 엔진(10) 및 엔진클러치(20)를 구동한다. That is, in the present invention, the control unit 50 drives the engine 10 and the engine clutch 20 more actively when the heating apparatus is operated in the EV mode running state, in which the vehicle is running after the initial running.

따라서, EV모드 주행 중 승객이 요구하는 난방온도를 구현하면서도 고전압 배터리(35)의 충전이 이루어지도록 하여, EV모드 주행 중 난방성능을 확보하고, 방전상황을 효과적으로 예방할 수 있다.Therefore, the high-voltage battery 35 can be charged while realizing the heating temperature required by the passenger during the EV mode travel, thereby securing the heating performance during the EV mode travel and effectively preventing the discharge situation.

상술한 바와 같은 구조로 이루어진 하이브리드 차량의 제어방법에 따르면, 하이브리드 차량이 EV모드로 정차하고 있는 상황에서 난방장치가 동작할 경우, 외기온 및 냉각수온에 따라 엔진이 구동되면서 엔진클러치가 함께 결합되는바, 구동되는 엔진이 모터와 연결된 고전압 배터리를 충전시켜 동력 낭비가 발생하는 것을 최소화할 수 있다.According to the control method of the hybrid vehicle having the above-described structure, when the heating device operates in a state where the hybrid vehicle is stopped in the EV mode, the engine clutch is coupled together while the engine is driven according to the outside temperature and the cooling water temperature , It is possible to minimize the occurrence of power waste by charging the high voltage battery connected to the motor by the driven engine.
